Find the values of x and y.
A. x = 73.3, y = 15.3
B. x = 73.3, y = 20.7
C. x = 100, y = 10
D. x = 100, y = 26
Answer:
C, (x = 100, y = 10)
Step-by-step explanation:
hi again,
(2x - 70) = (x + 30), by the Alternate Exterior Angles
x - 70 = 30
x = 100
(2x - 70) + 5y = 180, by the Linear Pair Theorem
2(100) - 70 + 5y = 180
200 - 70 + 5y = 180
130 + 5y = 180
5y = 50
y = 10
Movie critics claim that 68% of adults and 79% of teenagers would recommend seeing the newest action movie. Suppose random samples of 43 adults and 52 teenagers are selected. Let p hat Subscript Upper A and p hat Subscript Upper T be the sample proportions of adult and teenage moviegoers, respectively, who would recommend this movie.
Which of the following is the correct shape and justification of the sampling distribution of p hat Subscript Upper A Baseline minus p hat Subscript Upper T ?
bimodal because one population proportion is centered at 0.68, while the other is centered at 0.79
approximately Normal because the expected numbers of successes and failures for each sample are all at least 10
not approximately Normal because the expected numbers of successes and failures for each sample are all at least 10
not approximately Normal because the expected numbers of successes and failures for the adult group are not both at least 10
Answer:
approximately Normal because the expected numbers of successes and failures for each sample are all at least 10
Step-by-step explanation:
took the quiz
The simple random sampling is solved and is approximately normal because the expected numbers of successes and failures for each sample are all at least 10
What is simple random sampling ( SRS )?The most accurate type of probability sampling is random sampling. Each person in a population has an equal probability of getting selected for the sample thanks to this method of sampling.
This kind of sampling is perfect for highly controlled investigations where it is unacceptable to have human bias in the selection of the sample.
Each sampling unit in a population has an equal probability of being included in the sample when using simple random sampling (SRS). As a result, each potential sample has an equal probability of being chosen.
Given data ,
To determine the shape and justification of the sampling distribution of p hat Subscript Upper A Baseline minus p hat Subscript Upper T, we need to apply the Central Limit Theorem (CLT) since we have sample proportions from two populations.
The CLT states that if the sample size is sufficiently large, the sampling distribution of the difference between two sample proportions will be approximately normal, regardless of the distribution of the population proportions, as long as the expected numbers of successes and failures for each sample are all at least 10.
Since the sample sizes are n₁ = 43 and n₂ = 52, we can assume that the expected number of successes and failures for each sample are all at least 10, since both 0.68 * 43 = 29.24 and 0.32 * 43 = 13.76, and 0.79 * 52 = 41.08 and 0.21 * 52 = 10.92 are all greater than 10.
Hence , the sampling distribution of p hat Subscript Upper A Baseline minus p hat Subscript Upper T is approximately normal.

y = x2 – 7x - 6
Answer:
y = (x - 3.5)^2 - 18.25
Step-by-step explanation:
y = x^2 – 7x - 6
y = (x^2 – 7x) - 6
y = (x^2 – 7x + 3.5^2 - 3.5^2) - 6
y = (x^2 – (2)(3.5)x + 3.5^2) - 3.5^2 - 6
y = (x - 3.5)^2 - 3.5^2 - 6
y = (x - 3.5)^2 - 18.25

X + 4 < 6 help.......
Answer:
x<2
Step-by-step explanation:
Hello There!
Our objective for this problem is to isolate the variables
To do so we use inverse operations
x+4<6
subtract 4 from each side
4-4 cancels out
6-4=2
we're left with
x<2
Step-by-step explanation:
It is just like a normal x equation just with an inequality. So for now, just represent the < as and =
so we have x+4=6
subtract 4 from both sides
x+4-4=6-4
x=2
Now we insert the <
x<6
so all values for x are all less than 6
Hope that helps :)

Find the probability of getting two numbers whose sum is
8.The probability of getting two numbers whose sum is 8 is
Answer:
Your first answer is in picture:8. The possible outcomes when two dice are thrown together are:(1,1),(1,2),(1,3),(1,4),(1,5),(1,6),
(2,1),(2,2),(2,3),(2,4),(2,5),(2,6),
(3,1),(3,2),(3,3),(3,4),(3,5),(3,6),
(4,1),(4,2),(4,3),(4,4),(4,5),(4,6),
(5,1),(5,2),(5,3),(5,4),(5,5),(5,6),
(6,1),(6,2),(6,3),(6,4),(6,5),(6,6).
Therefore, the number of possible outcomes when two dice are thrown is 36.
Now, the possible outcomes of getting a sum equal to 8 is {(2,6),(3,5),(4,4),(5,3),(6,2)}, which means the number of favourable outcome is 5.
Therefore, probability P of getting a sum equal to 8 is:
P= 36/5
Hence, the probability of getting a sum equal to 8 is 36/5 .

Maggie Jay owns her own car. Her June monthly interest was $250. The rate is 13 1/2 percent. Jay's principal balance at the beginning of June is: (Use 360 days)
Answer:
the principal balance at the beginning of June is $22,222.22
Step-by-step explanation:
The computation of the principal balance at the beginning of June is shown below:
Principal balance = Interest paid ÷ (Interest Rate ÷ 12 Months)
= $250 ÷ (13.5% ÷ 12)
= $22,222.22
Hence, the principal balance at the beginning of June is $22,222.22

The system of equations 2y = 14 - 2x and y = -x + 7 is
graphed. What is the solution to the system of equations?
A. (0,-7)
B. No solution
C. (0,0)
B. Infinitely many solutions
Answer:
Step-by-step explanation:
Note that the two equations are equivalent.
2y = 14-2x can be rearranged to y = -x+7, which is the same as the second equation. What you're looking is one line on top of the other.
Every shared point is a solution. Since there are infinitely many points on a line, and these lines share every point, there are infinitely many solutions.
Help me as much as you can please :)
Answer:
Step-by-step explanation:
1). System of equations is,
-2x - y = -22 -------(1)
4x - 8y = 4 -------(2)
By satisfying these equations with the given point (9, 4),
Equation (1)
-2(9) - 4 = -22
-18 - 4 = -22
-22 = -22
True.
Equation (2)
4(9) - 8(4) = 4
36 - 32 = 4
4 = 4
True.
Given point lies on both the equations.
Therefore, the given point is the solution of the system of equations.
2). 3x - 3y = 27 -----(1)
-2x + 9y = -11 ------(2)
Satisfy the equations with the given point (-10, -1)
Equation (1)
3(-10) - 3(-1) = 27
-30 + 3 = 27
-27 = 27
False.
Equation (2)
-2x + 9y = -11
-2(-10) + 9(-1) = -11
20 - 9 = -11
11 = -11
False.
Therefore, the given point is not the solution of the system of equations given.

Twenty-five randomly selected students were asked the number of movies they watched the previous week. The results are as follows. # of movies Frequency 0 5 1 9 2 5 3 5 4 1 (a) Find the sample mean x. (Enter your answer to two decimal places.) x = (b) Find the approximate sample standard deviation, s. (Round your answer to two decimal places.) s =
Answer:
a) x = 1.52
b) s = 1.16
Step-by-step explanation:
We have that:
5 students watched 0 movies.
9 students watched 1 movie.
5 students watched 2 movies.
5 students watched 3 movies.
1 student watched 4 movies.
(a) Find the sample mean x.
Sum divided by the number of students. So
[tex]x = \frac{5*0 + 9*1 + 5*2 + 5*3 + 1*4}{5 + 9 + 5 + 5 + 1} = \frac{38}{25} = 1.52[/tex]
(b) Find the approximate sample standard deviation, s.
Standard deviation of the sample.
Square root of the sum of the squares of the values subtracted from the mean, divided by the sample size subtracted by 1. So
[tex]s = \sqrt{\frac{5*(0-1.52)^2 + 9*(1-1.52)^2 + 5*(2-1.52)^2 + 5*(3-1.52)^2 + 1*(4-1.52)^2}{24}} = \sqrt{\frac{32.24}{24}} = 1.16[/tex]
