Answer:
x-intercept: 4 y-intercept: - 6
Step-by-step explanation:
To find the y-intercept, we must first solve for y.
Isolate variable y on the left side of the equation by subtracting 3x from both sides.
- 2y = - 3x + 12
Now divide both sides by - 2 to find y.
y = 3/2x - 6
The y-intercept is - 6. (remember formula y = mx + b, where b is the y-intercept)
To find the x-intercept, we must solve for x.
Isolate variable x on the left side of the equation by adding 2y to both sides.
3x = 2y + 12
Now divide both sides by 3 to find x.
x = 2/3y + 4
The x-intercept is 4. (remember formula x = my + b, where b is the x-intercept)
Answer:
4 and - 6
Step-by-step explanation:
3x-2y=12
x= 0 ⇒ -2y=12 ⇒ y= -6y=0 ⇒ 3x= 12 ⇒ x= 4Translate “ the sum of x and one- half into a mathematical expression

Three roots of a fifth degree polynomial function f(x) are -2, 2, and 4 + i. Which statement describes the number and nature of
all roots for this function?
Of(x) has two real roots and one imaginary root.
f(x) has three real roots.
f(x) has five real roots.
Of(x) has three real roots and two imaginary roots.
We know that imaginary roots always come in pairs, so we already know 4 solutions
-2, 2, 4 + i and a pair of 4 + i
Since imaginary roots always come in pairs we wont have more than 2 imaginary roots, since its a fifth degree root and we can only have 5 roots
So for sure, we will have 3 real roots and 2 imaginary roots
Last option, f(x) has three real roots and two imaginary roots
Answer: ITS D (f(x) has three real roots and two imaginary roots)
For a certain instant lottery game comma the odds in favor of a win are given as 19 to 81. Express the indicated degree of likelihood as a probability value between 0 and 1 inclusive. The probability is nothing.(Round to two decimal places as needed.)
Answer:
The probability is 0.19.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
Odds in favor of a win are given as 19 to 81.
This means that for each 19 + 81 = 100 games played, there are expected to be 19 wins.
Express the indicated degree of likelihood as a probability value between 0 and 1 inclusive.
Desired outcomes:
19 wins, so D = 19.
Total outcomes:
100 games, so T = 100:
Probability:
[tex]p = \frac{D}{T} = \frac{19}{100} = 0.19[/tex]
The probability is 0.19.

Question: A biotechnology firm is planning its investment strategy for future products and research labs. A poll found that 14% of a random sample of 1043 adults approved of attempts to clone a human. Use this information to complete arts a through e.
a) Find the margin of error for this poll if we want 95% confidence in our estimate of the percent of adults who approve of the cloning humans.
ME = ____ (Round to three decimal places as needed.)
b) Explain what that margin of error means. (Select One.)
i) The pollsters are 95% confident that the margin of error contains the true proportion of adults who approve of attempts to clone a human.
ii) The margin of error is the value that should be subtracted from the 95% confidence level to obtain the pollsters� true confidence level.
iii) The margin of error is width of the confidence interval that contains the true proportion of adults who approve of attempts to clone a human.
iv) The pollsters are 95% confident that the true proportion of adults who approve of attempts to clone a human is within the margin of error of the estimated 14%.
c) If we only need to be 99% confident, will the margin of error be larger or smaller?
i) A 99% confidence interval requires a smaller margin of error. A wider interval leads to decreased confidence.
ii) A 99% confidence interval requires a larger margin of error. In order to increase confidence, the interval must be narrower.
iii) A 99% confidence interval requires a smaller margin of error. A narrower interval leads to decreased confidence.
iv) A 99% confidence interval requires a larger margin of error. In order to increase confidence, the interval must be wider.
d) Find that margin of error.
ME = ___ (Round to three decimal places as needed.)
e) In general, if all other aspects of the situation remain the same, would smaller samples produce smaller or larger margins of error?
Answer:
Step-by-step explanation:
Confidence interval is written as
Sample proportion ± margin of error
a) Margin of error = z × √pq/n
Where
z represents the z score corresponding to the confidence level
p = sample proportion. It also means probability of success
q = probability of failure
q = 1 - p
p = x/n
Where
n represents the number of samples
x represents the number of success
From the information given,
n = 1043
p = 14% = 14/100 = 0.14
q = 1 - 0.14 = 0.86
To determine the z score, we subtract the confidence level from 100% to get α
α = 1 - 0.95 = 0.05
α/2 = 0.05/2 = 0.025
This is the area in each tail. Since we want the area in the middle, it becomes
1 - 0.025 = 0.975
The z score corresponding to the area on the z table is 1.96. Thus, the z score for a confidence level of 95% is 1.96
Therefore, margin of error is 1.96√(0.14)(0.86)/1043
Margin of error = 0.021
b) i) The pollsters are 95% confident that the margin of error contains the true proportion of adults who approve of attempts to clone a human.
c) iv) A 99% confidence interval requires a larger margin of error. In order to increase confidence, the interval must be wider.
d) The z score for 99% confidence interval is 2.58
margin of error is 2.58√(0.14)(0.86)/1043
Margin of error = 0.028
e) smaller samples would produce smaller margins of error.

The cone pictured has a surface area of____a0 square meters. (Use 3.14 for π .)
Answer: A=286.2 m²
Step-by-step explanation:
The surface area of a cone is [tex]A=\pi r(r+\sqrt{h^2+r^2} )[/tex].
We are given h=11 m and r=5 m. With these values, we can plug them into the equation to find the surface area.
[tex]A=\pi (5)(5+\sqrt{11^2+5^2} )[/tex]
[tex]A=5\pi (5+\sqrt{146} )\\[/tex]
[tex]A= 268.2 m^2[/tex]
Answer:
The cone pictured has a surface area of_268.2___a0 square meters
Step-by-step explanation:
SA of a cone = πr² + πrs
s = slant height
s = √h² +r²
so combined together
SA of a cone = πr² + πr(√h² + r²) = πr(r +√h² + r²)
SA of a cone = 3.14*5(5+[tex]\sqrt{11^{2}+ 5^{2} }[/tex] ) =268.2038

Suppose that we want to estimate the mean reading speed of second graders. The random sample of students' reading speeds we choose has a mean of 31.6 words per minute and a standard deviation of 2.4 words per minute. For each of the following sampling scenarios, determine which test statistic is appropriate to use when making inference statements about the population mean. (In the table, Z refers to a variable having a standard normal distribution, and t refers to a variable having a t distribution.) Sampling Scenario could use either Zort unclear (1) The sample has size 100, and it is from a non-normally distributed population with a known standard deviation of 2.6. (2) The sample has size 75, and it is from a non-normally distributed population. (3) The sample has size 12, and it is from a population with a distribution about which we know very little. (4) The sample has size 14, and it is from a normally distributed population with a known standard deviation of 2.6. (5) The sample has size 16, and it is from a normally distributed population with unknown standard deviation.
Answer:
Step-by-step explanation:
Hello!
Given the variable
X: reading speed of a second-grader. (words per minute)
From a random sample of second-grader the mean and standard deviation were:
X[bar]= 31.6 words per minute
S= 2.4 words per minute
To study the population mean (μ) you have the following sampling scenarios and need to choose the correct statistic.
Sampling scenarios:
(1) The sample has size 100, and it is from a non-normally distributed population with a known standard deviation of 2.6.
For this scenario you have to remember the Central Limit Theorem. The variable of study has a non-normal distribution but the sample is large enough (As a rule, a sample of size greater than or equal to 30 is considered sufficient to apply the theorem and use the approximation) you can approximate the distribution of the sample mean to normal: X[bar]≈N(μ;σ²/n); Then it is valid to use an approximation to the standard normal distribution to make inference statements about the population mean.
Statistic: Z
(2) The sample has size 75, and it is from a non-normally distributed population.
Same explanation as the statement before, except that the population variance is unknown. Since the distribution is already an approximation you can use its estimation (sample variance) for the statistic. (It would be less accurate than using the population variance but still valid)
Statistic: Z
(3) The sample has size 12, and it is from a population with a distribution about which we know very little.
To use a student's t the population needs to have a normal distribution, which is not the case, same goes for the standard normal.
To apply the central Limit Theorem you need a sample size equal or greater to 30, this is not the case.
For this sampling example neither distribution is applicable.
(4) The sample has size 14, and it is from a normally distributed population with a known standard deviation of 2.6.
The population has a normal distribution and the population standard deviation is known. The sample size is rather small but it isn't an impediment to apply the standard normal distribution. Also, even tough the population standard deviation is known, a student t is also applicable. In this case both statistics are a viable option.
Statistic: Z or t
(5) The sample has size 16, and it is from a normally distributed population with unknown standard deviation.
The population has a normal distribution, with unknown population standard deviation and the sample size is rather small. You can use a Student t to infer over the population mean.
Statistic: t

Step-by-step explanation:
The point-slope form of the equation of a line is ...
y -h = m(x -k)
for a line with slope m through point (h, k).
Comparing this to the given equation, you see that ...
h = -2, m = 1, k = -4
The line has a slope of 1 and goes through the point (-4, -2). This information is useful for graphing.

Answer:
19.4ft
Step-by-step explanation:
A parallelogram has two sides parallel and equal meaning the top and bottom length are the same;
Meaning if the top is C, the bottom is C.
Similarly the length at the right side equals that on the left;
That means the the left = 60.4ft
Perimeter means distance round
And perimeter =157.6ft
Meaning if we start from the Top, it means:
C+ 60.4ft + C + 60.4ft= 157.6ft
C + C + 60.4ft+ 60.4ft = 157.6ft
2C + 120.8 = 157.6
2C = 157.6 - 120.8
2C= 36.8
C = 36.8/2
C= 19.4ft
You can calculate C from here

The pitcher releases the ball at the highest point in the curve, and the catcher is located at the y-axis. According to the table, how high is the ball when it reaches the catcher?
Answer: 2.5 ft
Step-by-step explanation:
Ok, we know that the catcher is located in the y-axis.
As you know, the y-axis cuts the x-axis at x = 0, so the catcher is located at x = 0.
To see the heigth of the ball at x = 0 we can see the table, where we can see that when x = 0, f(x) = 2.5 ft
Then the correct option is the second one, 2.5 ft.
Answer:
The answer is A. 2.5
The first option
Step-by-step explanation:
If we look at the question you'll see this phrase "X represents the horizontal distance the ball travels in feet" and "f(x) represents the height of the ball in feet."
The question is "The pitcher releases the ball at the highest point in the curve, and the catcher is located at the y-axis. According to the table, how high is the ball when it reaches the catcher?" the underlined words are your clue.
When the graph hit zero, its hit its mark "The catcher" it REACHES the catcher.

Producția de carne pe animal obținută de la un porc de rasă non-superioară = 4,8 kg de carne pe o rasă de porc non-superioară.
Step-by-step explanation:
English Translation
A quarter of the number of pigs on the farm, being of superior breed, bring at the end of the year, on average, a production of 9.6 kg of meat per animal. The production thus obtained represents half of total meat production, Determine the meat production per animal obtained from a non-superior breed pig.
Solution
Let the meat production per animal for the non superior breed of pig be y
Let the total number of pigs be x
A quarter of the pigs are superior breed, 0.25x, bring in 9.6 kg of meat per superior breed of pigs.
Total amount of meat produced by the superior breed of pigs = 0.25x × 9.6 = (3.6x) kg
This means that there are three quarter pigs from the less superior breed, 0.75x, making y kg of meat per animal.
Total amount of meat produced by the non superior breed of pigs = 0.75x × y = 0.75xy kg
Total meat production = (3.6x + 0.75xy) kg
It is then given that the total amount of meat from the superior breed is half of the total meat production.
That is,
3.6x = (3.6x + 0.75xy)/2
7.2x = 3.6x + 0.75xy
7.2x - 3.6x = 0.75xy
3.6x = 0.75xy
y = (3.6/0.75) = 4.8 kg
Hence, the meat production per animal obtained from a non-superior breed pig = 4.8 kg of meat per non superior breed of pig.

Permiteți producția de carne pe animal pentru rasa non superioară de porc
Fie numărul total de porci x
Un sfert din rasa superioară, 0,25x, aduce 9,6 kg de carne pentru fiecare rasă superioară de porci.
Un sfert din porci sunt de rasa superioară, 0,25x, aduc 9,6 kg de carne pe rasă superioară de porci.
Cantitatea totală de carne produsă de rasa superioară de porci = 0,25x × 9,6 = (3,6x) kg
Aceasta înseamnă că există trei sferturi de porci de la rasa mai puțin superioară, 0,75x, ceea ce face y kg de carne pe animal.
Cantitatea totală de carne produsă de rasa non superioară de porci = 0,75x × y = (0,75xy) kg
Producția totală de carne = (3,6x + 0,75xy) kg
Se consideră că cantitatea totală de carne de la rasa superioară este jumătate din producția totală de carne.
Acesta este,
3,6x = (3,6x + 0,75xy) / 2
7,2x = 3,6x + 0,75xy
7,2x - 3,6x = 0,75xy
3,6x = 0,75xy
y = (3,6 / 0,75) = 4,8 kg
Prin urmare, producția de carne pe animal obținută de la un porc de rasă non-superioară = 4,8 kg de carne la o rasă de porc ne superioară.

Part 4
For this case since the p value is higher than the significance level so then we FAIL to reject the null hypothesis and we can conclude that the true proportion is not significantly less than 0.4
a. Fail to reject the null hypothesis
Find the value of x and y in the parallelogram below.
Answer:
x=4 and y = 12
Step-by-step explanation:
A diagonal of a parallelogram cuts the other diagonal in exactly 2 equal parts. So, we can say that x+12 = 16. That would give us x=4. And, we can say that 3y-14 = 22. If we solve for y, we get y = 12.
What is the value of the expression below?
Answer:
(7÷2)-(4.5*3)+8
(3.5)-(13.5)+8
3.5-5.5=-2
A chicken weighs t lbs. It needs to be cooked for 20 minutes per lb plus an extra 15 minutes. What is the total cooking time? Is this the correct written expression: 15t + 20? Why or why not?
Answer:
Total cooking time = 20t + 15
The expression 15t + 20 is wrong.
Step-by-step explanation:
weight of chicken = t lbs
cook time per lb = 20 minutes
This means that:
1 lb weight requires a cooking time of 20 minutes
1 lb = 20 minutes
∴ t lbs = 20 × t = 20t minutes.
We were also told that each chicken required an extra cooking time of 15 minutes, in addition to the total cooking time due to the weight. Therefore, the total cooking time is calculated thus:
Total cooking time = cooking time due to weight + 15 minutes
Total cooking time = 20t + 15
Hence the expression 15t + 20 is wrong, due to the explanation given above.
