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%

Does the Y-axis or X-axis come first?

Step-by-step explanation:
The X-axis is the one on the bottom if you are in the first quadrant. The y-axis is on the left or up and down. If you are writing location(I can't remember the name but it looks like this (2,3)) you would write the X-axis down first. Hope this helped!
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.

Circuit City is having a sale on computers. Max picks out a computer that was originally $1199.99 If the computer is 41% off, What is the final price of the computer? Round to the nearest penny.
Answers
Answer:
$707.9941 rounded is $707.99
Step-by-step explanation:
41%=0.41
1199.99*0.41=491.9959
$1199.99-$491.9959=$707.9941
$707.9941 rounded is $707.99
the four doesn't round up so it would just be $707.99.

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

Suppose the probability of a false positive result on a mammogram is 4%. Suppose that the probability of a false negative result on a mammogram is 2%. Assume that the probability that a randomly chosen woman has breast cancer is 0.0002. If a woman has a positive test result, what is the probability that she actually has breast cancer
Answers
Answer:
0.0049 = 0.49% probability that she actually has breast cancer
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
In which
P(B|A) is the probability of event B happening, given that A happened.
[tex]P(A \cap B)[/tex] is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: Positive test result
Event B: Breast cancer
Probability of a positive test result:
4% of (1 - 0.0002)
98% of 0.0002
So
[tex]P(A) = 0.04*(1 - 0.0002) + 0.98*0.0002 = 0.040188[/tex]
Having breast cancer and testing positive.
98% of 0.0002
So
[tex]P(A \cap B) = 0.98*0.0002 = 0.000196[/tex]
What is the probability that she actually has breast cancer?
[tex]P(B|A) = \frac{0.000196}{0.040188} = 0.0049[/tex]
0.0049 = 0.49% probability that she actually has breast cancer

c)A = 90°; C = 60°; c = 12
d)no solutions
Answers
Answer:
No solution.
Step-by-step explanation:
Given
[tex]a = 14; b= 12; B = 90^\circ[/tex]
Required
Find all possible solutions
If [tex]B = 90^\circ[/tex], then the triangle is right-angled and the hypotenuse is at b
Given that [tex]a = 14; b= 12;[/tex]
This implies that a > b
In a right-angled triangle, the hypotenuse (side b) is the longest.
Since this is not true for the given sides, then the triangle has no solution.

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
