Answer: D. 3 2/3 - 2
Step-by-step explanation: If you add up all of the boxes, you get 3 4/6, which is simplified to 3 2/3. Then, subtract the marked boxes (which equal 1 2/3) from 3 2/3 and you get 2. Hence, your answer: 3 2/3 - 2 (= 1 2/3)

Answers
Answer: B. 44.7
Step-by-step explanation: I believe it's the answer but I'm not sure.
A Z-score helps us to understand how far is the data from the mean. The correct option is D. The weight will be 54.6 grams.
What is Z-score?A Z-score helps us to understand how far is the data from the mean. It is a measure of how many times the data is above or below the mean. It is given by the formula,
Z = ( X - μ ) / σ
Where Z is the Z-score,
X is the data point,
μ is the mean and σ is the standard variable.
The weight of a randomly selected pack of gum has a z-score of 3.11. Therefore, The weight of this pack of gum is heavier than the mean weight by 3.11 standard deviations.
Z = ( X - μ ) / σ
3.11 X 2.4 = X - 47.1
X = 54.6 grams
Hence, the correct option is B.

Does anybody know what measures a, b, and c would be?
Answers
Answer: A = 28 B = 47 C = 105 in degrees
Step-by-step explanation:
OKAY JUST A DISCLAIMER:
I did Geometry last year and the concepts are basically gone but I think I remember how to do this one
So I think one of the theorems stated that the inner angle is half of the outer arc.
So.. angle a would be 56/2 = 28
Angle b would be 94/2 = 47
Angle C is a vertical angle to the angle in the triangle, so it would be 180-47-28=105

The proportion of twins born in a town is p = 0.12. Suppose we randomly select 100 women from this town who give birth in the next year.
Which of the following is the correct calculation and interpretation of the standard deviation of the sampling distribution of p hat ?
Sigma Subscript p hat Baseline = 0.001 In SRSs of size 100, the sample proportion of women in this town giving birth to twins typically varies 0.001 from the true proportion, p = 0.12.
Sigma Subscript p hat Baseline = 0.032 In SRSs of size 100, the sample proportion of women in this town giving birth to twins typically varies 0.032 from the true proportion, p = 0.12.
Sigma Subscript p hat Baseline = 0.035 In SRSs of size 100, the sample proportion of women in this town giving birth to twins typically varies 0.035 from the true proportion, p = 0.12.
Sigma Subscript p hat Baseline = 0.106 In SRSs of size 100, the sample proportion of women in this town giving birth to twins typically varies 0.106 from the true proportion, p = 0.12.
Answers
Answer:
B. Sigma Subscript p hat Baseline = 0.032 In SRSs of size 100, the sample proportion of women in this town giving birth to twins typically varies 0.032 from the true proportion, p = 0.12.
Step-by-step explanation:
took the quiz
The correct calculation and interpretation of the standard deviation of the sampling distribution of p hat is the sample proportion of women in this town giving birth to twins typically varies 0.032 from the true proportion, 0.12.
What is random sample?Random sample is the way to choose a number or sample in such a manner that each of the sample of the group has an equal probability to be chosen.
The standard deviation of the sampling distribution of p hat is given as,
[tex]\sigma_{ \hat p}=\sqrt\dfrac{p(1-p)}{n}[/tex]
Here, p is the proportion and n is the number of sample.
The proportion of twins born in a town is p = 0.12. Now there is randomly select 100 women from this town who give birth in the next year.
[tex]\sigma_{ \hat p}=\sqrt{\dfrac{0.12(1-0.12)}{100}}\\\sigma_{ \hat p}=\sqrt{0.001056}\\\sigma_{ \hat p}=0.032[/tex]
Thus, the correct calculation and interpretation of the standard deviation of the sampling distribution of p hat is the sample proportion of women in this town giving birth to twins typically varies 0.032 from the true proportion, 0.12.

Shaquana is playing a board game. The probability that Shaquana will lose a turn on
her next turn is 12. Which word or phrase describes the probability that Shaquana
will lose a turn?
Answers
Answer:
Unlikely
Step-by-step explanation:
50/50 means that there is half a chance to loose a turn or 6/12 which is not the case.
Certain is definitely not correct as there is only 1/12 of a chance.
And impossible is not possible because it would have to be 0/12. There is still a chance to loose a turn with 1/12
Write and solve an equation to find the value of x and the missing angle measures.
1.
2.
6x
(4 + 5x)
30°
(x + 2)
3.
Answers
Answer:
Step-by-step explanation:
1). Since, both the angles are vertically opposite angles,
Measure of both the angles will be same.
6x = 30
x = 5
2). Since, both the angles are the linear pair of angles,
(4 + 5x)° + (x + 2)° = 180°
6x + 6 = 180
6x = 180 - 6
x = [tex]\frac{174}{6}[/tex]
x = 29
Therefore, (4 + 5x)° = 4 + 5(29)
= 149°
And (x + 2)° = (29 + 2)
= 31°
3). Since, both the angles are linear pair of angles,
5x° + (3x + 12)° = 180°
8x + 12 = 180
8x = 180 - 12
x = [tex]\frac{168}{8}[/tex]
x = 21
Therefore, 5x° = 5(21)
= 105°
(3x + 12)° = 3(21) + 12
= 75°

Janice babysat 3 hours each night for 8 nights. She earned a total of $192 babysitting. What was her hourly rate?
A) $3 per hour
B) $8 per hour
C) $24 per hour
D) $192 per hour
Answers
Answer:
1) 7:10
2) $8 per hour
Step-by-step explanation:
Question 1
What we know:
- there are 10 seventh grade students
- there are 7 sixth grade students
Therefore, the ratio of sixth-grade students to seventh-grade students is 7:10.
Question 2
What we know:
- Janice babysat 3 hours each night
- Janice babysat for 8 nights
- she earned $192
First, we need to find the total number of hours that she babysat. Because she babysat for 3 hours each night for 8 nights, we can find this by multiplying 3 and 8:
3×8=24
Therefore, Janice babysat for 24 hours in total.
Because she earned a total of $192, divide 192 by 24 to find her hourly rate:
192÷24=8
Therefore, Janice has an hourly rate of $8 per hour.
