Answer:
(D) y = 2x - 5
Step-by-step explanation:
First locate where the line touches the y axis or vertical axis. Then find the rise over run or rate of change (slope) by using the triangle method.
I call this the triangle method because it involves drawing vertical(up, and down), and horizontal(left, and right) lines from the original or diagonal line (hypotenuse or longest line) to create a right (90 degree, because the angle between them forms a square) triangle. First draw a line going to the right from a point on the original line, and form a triangle by connecting the next point with a line going up, and down (vertical line) with the line going to the right (horizontal line)
Then count the units of the vertical line and divide them by the units counted by the horizontal line.
This is k(for constant) or m(slope or steepness of a graph ) = change in or rise of y divided by the change in or rise of x = ∆y(change in or rise of y)/∆x(change in or run of x).
For this graph, starting from -5 or the point where the line touches the y axis. Draw a line going up 1 square to the right, and another going up 2 squares. Repeat this, and you will realise that it's the same pattern every time. Because the line goes up 2 squares, every time it goes to the right 1 square. There is a change of 2 in y every change of 1 in x or rise of 2 for every run of 1. Therefore, the slope is 2/1 = 2. Then since we know the graph touches the y axis at -5, y = 2x - 5

Suppose that E and F are points on the number line. If EF=5 and F lies at -3, where could E be located?
Answers
Answer:
There are two possible locations. E could be located in either -8 or 2.
Step-by-step explanation:
The number line is a one-dimensional graphing model for real numbers, in which each element is represented by points. Under this system, there are two directions:
[tex]-x[/tex] - Left semiaxis that corresponds to negative real numbers.
[tex]+x[/tex] - Right semiaxis that corresponds to positive real numbers.
Both semiaxis are divided by origin, which represents the real number zero.
Let E and F points on the number. If we know that [tex]F = -3[/tex] and [tex]EF = 5[/tex], there are two choices for the location of E. That is:
[tex]E_{1} = F+EF[/tex]
[tex]E_{1} = -3+5[/tex]
[tex]E_{1} = 2[/tex]
[tex]E_{2} = F-EF[/tex]
[tex]E_{2} = -3 -5[/tex]
[tex]E_{2} = -8[/tex]
There are two possible locations. E could be located in either -8 or 2.

Fran is making pancakes. The recipe for the pancakes calls for 1/8 teaspoon of salt for every 3/4 cup of flour. Fran makes an amount of pancakes that needs 18 cups of flour. How much salt, in teaspoons, does Fran need to use for the pancakes?
Answers
Answer:
3 teaspoon
Step-by-step explanation:
If for every 3/4 cup of flour we will need 1/8 teaspoon of salt, then:
1/8 teaspoon = 3/4 cup of flour
To get the amount of teaspoon needed for 18cups we will say:
x teaspoon = 18 cups
Solving both equalities for x:
1/8 teaspoon = 3/4 cup of flour
x teaspoon = 18 cups
Cross multiply
3/4 * x = 18 * 1/8
3x/4 = 18/8
cross multiply again
3x*8 = 4*18
24x = 72
x = 72/24
x = 3
Hence Fran needs 3 teaspoon of salt fir 18cups of flour

Roland’s remote control boat has a max speed of 25 miles per hour. How many miles can Roland’s boat travel in 1/3 of an hour?
Answers
We can set this problem up as a ratio (or as a proportional type of problem).
When somebody is traveling 25 miles per hour, for every hour passed they have rode (or driven) 25 miles. This ratio can be set up as 25:1. We want to get it to where the 1 in the ratio is 1/3 because we want it to be 1/3 of an hour.
When dealing with ratios, you always want to do one thing on both sides of it is ever changed. In this case we want to get 1 to 1/3. To get 1 to 1/3 we need to DIVIDE by 3 because 3 will be under 1, therefore 1/3.
The ratio will look like 25:1/3 WHEN IT IS INCOMPLETE. We then need to remember we need to do everything on one side to the other, therefore we need to divide 25 by 3 which will give us 8.333333 or 8 and 1/3 (8 1/3)

What are the coordinates of the x-intercept of the line 2x-5y=10 ?
Answers
Answer:
(5, 0) is the x intercept.
Step-by-step explanation:
Given equation of the line is 2x - 5y = 10
For y-intercept of the line we find the value of y by substituting x = 0 in the given equation.
Similarly, for x-intercept we will substitute the value y = 0 and find the value of x.
2x - 5(0) = 10
2x = 10
x = 5
Therefore, y-intercept of the given line is (5, 0).

At the Fidelity Credit Union, a mean of 7.1 customers arrive hourly at the drive-through window. What is the probability that, in any hour, less than 2 customers will arrive
Answers
Answer:
The probability that, in any hour, less than 2 customers will arrive is 0.0067.
Step-by-step explanation:
The random variable X can be defined as the number of customers arriving hourly at the drive-through window at the Fidelity Credit Union.
The random variable X describes a finite number of occurrences of an event in a fixed time interval.
The random variable X follows a Poisson distribution with parameter λ = 7.1.
The probability mass function of X is:
[tex]P(X=x)=\frac{e^{-7.1}(7.1)^{x}}{x!};x=0,1,2,3...[/tex]
Compute the probability of less than 2 customers arriving as follows:
[tex]P(X<2)=P(X=0)+P(X=1)[/tex]
[tex]=\frac{e^{-7.1}(7.1)^{0}}{0!}+\frac{e^{-7.1}(7.1)^{1}}{1!}\\\\=0.00083+0.00586\\\\=0.00669\\\\\approx 0.0067[/tex]
Thus, the probability that, in any hour, less than 2 customers will arrive is 0.0067.

Question 9 Of 1000 randomly selected cases of lung cancer, 841 resulted in death within 10 years. Construct a 95% two-sided confidence interval on the death rate from lung cancer. (a) Construct a 95% two-sided confidence interval on the death rate from lung cancer. Round your answers to 3 decimal places.
Answers
Answer:
0.818335 ≤ p ≤ 0.86366
Step-by-step explanation:
Given that:
Sample size (n) = 1000
Positive lung cancer = 841
n(p) = 841, p(p) = 841/1000 = 0.841
n(1 - p) = 1000 - 841 = 159
1 - p = 0.159
95% confidence interval
For a 95% confidence interval : z = 1.96
P ± z√p(1-p) / n
0.841 ± 1.96 * √0.841(0.159) / 1000
0.841 - (1.96 * 0.0115636) = 0.818335344
0.841 + (1.96 * 0.0115636) = 0.863664656
0.818335 ≤ p ≤ 0.86366
One package of blackberries costs $3. How many packages of blackberries can you buy for $15?
Answers
Answer:
5 packages
Step-by-step explanation:
One package of blackberries cost $3
Let x represent the number of packages that will cost $15
1 = $3
x= $15
3x= 15
Divide both sides by the coefficient of x which is 3
3x= 15/3
x= 5
Hence 5 packages of blackberries will cost $15

An airline promotion to business travelers is based on the assumption that two-thirds of business travelers use a laptop computer on overnight business trips. a. State the hypotheses that can be used to test the assumption. H 0: p Select H a: p Select b. What is the sample proportion from an American Express sponsored survey that found 355 of 546 business travelers use a laptop computer on overnight business trips
Answers
Answer:
a
The null hypothesis is [tex]H_o : p = 0.67[/tex]
The alternative hypothesis is [tex]H_a : p \ne 0.67[/tex]
b
The sample proportion is [tex]\^ p = 0.65[/tex]
Step-by-step explanation:
From the question we are told that
The sample size is n = 546
The number of people that use a laptop overnight is [tex]k = 355[/tex]
The population proportion is [tex]p = \frac{2}{3} = 0.67[/tex]
Generally
The null hypothesis is [tex]H_o : p = 0.67[/tex]
The alternative hypothesis is [tex]H_a : p \ne 0.67[/tex]
Gnerally the sample proportion is mathematically represented as
[tex]\^ p = \frac{ k}{n}[/tex]
=> [tex]\^ p = \frac{ 355}{546}[/tex]
=> [tex]\^ p = 0.65[/tex]
