- 3x² + 14x- 8
Answer =
= - 3x² + 14x - 8
= - 3x² + 12x + 2x - 8
= - 3x(x - 4) + 2(x - 4)
= (x - 4)(-3x + 2)
solve for a, 1/3 + a = 5/4
Answer:
[tex]a = \frac{11}{12}[/tex]
Step-by-step explanation:
[tex]a = \frac{5}{4} - \frac{1}{3}[/tex]
[tex]a = \frac{11}{12}[/tex]
Answer:
[tex] \frac{1}{3} + a = \frac{5}{4} [/tex]
[tex]a = \frac{5}{4} - \frac{1}{3} [/tex]
[tex]a = \frac{15 - 4}{12} [/tex]
[tex]a = \frac{11}{12} [/tex]

What is the slope of the line shown in the graph?
A. -3/2
B. -1/2
C. 3/2
Answer:
-3/2
Step-by-step explanation:
Answer:
The slope of the line shown is -3/2.
Step-by-step explanation:
You can find this by using the rise/run method between the two points.
Between the two points, the line falls 3 units down (this is the rise part) and goes 2 units to the right (this is the run part). Since the line falls 3 units down between the two points, this number would be -3, and since it runs to the right by two units, the slope can be identified as -3/2.

4/5 - 2/3 =
Find equivalent fractions and rewrite the problem and solve
Answer:
1001/1500
Step-by-step explanation:
The easiest method for doing this is to just average the two numbers.
e.g. to find a number x between the two numbers ab and cd
x=12[ab+cd]
=12[adbd+bcbd]
=ad+bc2bd
In this case…
x=(2×5)+(3×4)2×2×5=10+1230=2230=1115
You can easily see where that came from.
23=1015 and 45=1215
and the ‘common denominator’ means you just have to pick a value between 10 and 12 . i.e. 11
But you can also say…
23=100150 and 45=120150
and choose any of 101150,102150,...,119150
or
23=10001500 and 45=12001500
and choose any of 10011500,10021500,...,11991500
Answer:4/5 and 2/3 each have a common bottom of 15 so 4/5 is
12/15 and 2/3 will be 10/15
Step-by-step explanation:So than 12/15 forget the bottom don't subtract the bottom just look at it like [12-10] then you got 2 then you go back to the bottom and put it together so your answer is [2/15]

Consider the question of whether the home team wins more than half of its games in the National Basketball Association. Suppose that you study a simple random sample of 80 professional basketball games and find that 52 of them are won by the home team. Assuming that there is no home court advantage and that the home team therefore wins 50% of its games in the long run, determine the probability that the home team would win 65% or more of its games in a simple random sample of 80 games
Answer:
0.0037 = 0.37% probability that the home team would win 65% or more of its games in a simple random sample of 80 games
Step-by-step explanation:
To solve this question, we need to understand the normal probability distribution and the central limit theorem.
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]
The home team therefore wins 50% of its games
This means that [tex]p = 0.5[/tex]
Determine the probability that the home team would win 65% or more of its games in a simple random sample of 80 games
Sample of 80 means that [tex]n = 80[/tex] and, by the Central Limit Theorem:
[tex]\mu = p = 0.65[/tex]
[tex]s = \sqrt{\frac{p(1-p)}{n}} = \sqrt{\frac{0.5*0.5}{80}} = 0.0559[/tex]
This probability is 1 subtracted by the pvalue of Z when X = 0.65. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{0.65 - 0.5}{0.0559}[/tex]
[tex]Z = 2.68[/tex]
[tex]Z = 2.68[/tex] has a pvalue of 0.9963
1 - 0.9963 = 0.0037
0.0037 = 0.37% probability that the home team would win 65% or more of its games in a simple random sample of 80 games
José is making frult-filled tart shells for a party. He has 80 raspberries and 48 blueberrles. The tarts will each
have the same number of berrles. Raspberrles and blueberrles will not be in the same tart If he puts the
greatest possible number of fruits in each tart, how many tarts can he make?
When the greatest possible number of berrles Is In each tart, there are
tarts In total.
Answer:8
Step-by-step explanation:the GCF for 80 and 48 is 16 so divide 80 by 16 and you will get 5 and 48 by 16 and you’ll get 3 and when you and 5 and 3 you’ll get 8 as your answer.

Answer:
yes
Step-by-step explanation:
I think you mean
"Is the product of 3/6 × 5/4 equal to the product of 3/4 × 5/6?"
If we can turn 3/6 * 5/4 into 3/4 * 5/6 using only legal math steps, then the answer is yes.
3/6 * 5/4 =
Breakup each fraction into a product of fractions.
= 3/1 * 1/6 * 5/1 * 1/4
Use the associative and commutative properties of multiplication to change the order and grouping of the multiplication.
= (3/1 * 1/4) * (5/1 * 1/6)
Do each product in parentheses.
= 3/4 * 5/6
This shows that 3/6 * 5/4 = 3/4 * 5/6
