Amar thinks of a number If he takes away 6 from ⅔ ? of number, the result is
22. Find the number.
Answers
Let's assume the number as x
According to the question,
2/3x-6=22
2x-6=22×3
2x= 66-6
2x=60
x=60/2=30
Therefore, as x=30, The number is 30 itself.
AT&T would like to test the hypothesis that the average revenue per retail user for Verizon Wireless customers is greater than $50. A random sample of 32 Verizon Wireless customers provided an average revenue of $54.70. It is believed that the population standard deviation for the revenue per retail user is $11.00. Using LaTeX: \alpha=0.05α = 0.05 , answer the following questions: a. Identify the null and alternative hypotheses to conduct an appropriate hypothesis test of mean. (3 points) b. Use the critical value approach to test this hypothesis. (3 points) State your decision and conclusions explicitly. (3 points) c. Use the p-value approach to test this hypothesis. (3 points) State your decision and conclusions explicitly. (3 points) d. Assume that the actual population mean for revenue per retail user is $44.30. Calculate the probability of type II error. (5 points)
Answers
Answer:
H0; u = 50 average revenue equals 50
H1: u not equal to 50, average revenue not equal to 50
This is 2 tailed
Alpha = 0.05
Z critical = 1.6449
We find the test statistics
Mean = 54.7
Sd = 11
n = 32
barX - u/sd/√n
= 54.70-50/11/√32
= 4.70/1.9435
= 2.418
Decision rule: reject H0 if test statistic > critical value. Accept if otherwise
2.418>1.6449
We reject H0
We conclude that average revenue is not equal to zero
C. P(z>=2.418) = 0.9922
1 - 0.9922
= 0.0078 (I used Ms excel here)
0.0078 < 0.05
So we Reject h0

A group of tenth grade students responded to a survey that was asked which Math course they were currently enrolled in. The survey data were broken down as shown in the table above. Which of the following categories accounts for approximately 19% of all survey respondents?
A. Females taking Geometry
B. Females taking Algebra II
C. Males taking Geometry
D. Males taking Algebra I
Answers
Answer:
C.
Step-by-step explanation:
The bottom-right most cell tells us that the total number of students that responded to the survey is 310 students.
To find the answer, we can go through each choice.
A. Females taking Geometry
Row 1 Column 2 tells us that 53 females are taking geometry. 53/310 is about 17%.
B. Females taking Algebra II.
Row 1 Colume 3 tells us that 62 females are taking Algebra II. 62/310 is 20%.
C. Males taking Geometry.
Row 2 Colume 2 tells us that 59 males are taking Geometry. 59/310 is about 19%. Choice C is correct.
D. Males taking Algebra I.
44 out of the total 310 respondents are male and is taking Algebra I. 44/310 is about 14%.
Answer:
C
Step-by-step explanation:
59/310 *100 = 19.03%
so 19%

7x + 3y = 8
6x – 3y = 5
For the solution (x,y) to the system of equations
above, what is the value of x - y ?
Answers
Answer:
2/3
I have made in above picture
hope it helps
For the solution [tex](3,\frac{1}{3})[/tex] of the given system of equations, the value of x - y is [tex]2\frac{2}{3}[/tex]
To determine the value of x - y, we will solve the two equations simultaneously
We have
7x + 3y = 8 ------ (1)
6x – 3y = 5 ----- (2)
Solving by the elimination method
Add equations (1) and (2) together
We get
[tex]7x + 6x +3y -3y = 8 + 5[/tex]
Then,
[tex]13x = 13[/tex]
Now, divide both sides by 13
[tex]\frac{13x}{13} = \frac{13}{13}[/tex]
∴ [tex]x = 1[/tex]
Now, substitute the value of x into equation (1)
[tex]7x + 3y = 8[/tex]
We get
[tex]7(1) + 3y = 8[/tex]
[tex]7 + 3y = 8[/tex]
[tex]3y = 8-7[/tex]
Then,
[tex]3y = 1[/tex]
Divide both sides by 3
[tex]\frac{3y}{3} =\frac{1}{3}[/tex]
∴ [tex]y = \frac{1}{3}[/tex]
The solution to the system of equations is [tex](3,\frac{1}{3})[/tex]
Now, for the value of x - y, we will input the values of x and y
That is,
[tex]x -y = 3 -\frac{1}{3}[/tex]
[tex]= 2\frac{2}{3}[/tex]
∴ [tex]x-y =2\frac{2}{3}[/tex]
Hence, the value of x - y is [tex]2\frac{2}{3}[/tex]

How many solutions does the inequality x > 12 have? Explain.
Answers
Answer:
Infinite solutions
Step-by-step explanation:
Suppose there are finite solutions to x > 12
Then there exists a largest solution, which we call X
But X + 1 > X, and X > 12, so by transitivity X + 1 > 12 and thus is an even larger solution
this means X is not the largest solution
Therefore, by contradiction, the assumption that there are only finite solutions is false

If you roll two six-sided dice, what is the probability that at least one dies shows a 5 ?
Answers
Answer:
[tex]\frac{11}{36} = 0.3056[/tex] probability that at least one dies shows a 5.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
Each dice:
6 sides, one of which is 5.
So 6-1/6 = 5/6 probability of rolling a 5.
Probability of not rolling a five in two rolls:
(5/6)^2 = 25/36
Probability of rolling a five in at least one of the rolls:
[tex]p = 1 - \frac{25}{36} = \frac{36}{36} - \frac{25}{36} = \frac{11}{36} = 0.3056[/tex]
[tex]\frac{11}{36} = 0.3056[/tex] probability that at least one dies shows a 5.
