Answer:
A = 22.5 ft^2
Step-by-step explanation:
This shape is a rectangle of length 30' and width 3/4'.
The area of a rectangle of length L and width W is A = L * W.
Here, with L = 30' and W = (3/4)', A = (30')(3/4') = 45/2 ft^2, or A = 22.5 ft^2

Step-by-step explanation:
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.
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.

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.

Does anybody know what measures a, b, and c would be?
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
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.
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°
A square is 5 inches on each side. A small square, x inches on each side, is cut out from each corner of the original square. Represent the area of the remaining portion of the square in the form of a polynomial function A(x).
Answer:
A(x)= (5×5)-[4(x×x)]Hope this helps!4g + 12 < 60 solve and graph
Answer:
g<12
Step-by-step explanation:
4g+12<60
Subtract 12 from both sides.
4g<60−12
Subtract 12 from 60 to get 48.
4g<48
Divide both sides by 4. Since 4 is positive, the inequality direction remains the same.
g<48/4
Divide 48 by 4 to get 12.
g<12

The lengths in cm, of the sides of a triangle are 3x - 5, 2x-1 and x+1
3x - 5
2x - 1
(a) Write down an expression, in terms of x, for the perimeter of the triangle
(2)
The perimeter of the triangle is 31 cm.
(b) Work out the value of x.
Answer:
a) p = 6x - 5
b) x = 6
Step-by-step explanation:
a) p = a + b + c
p = 3x - 5 + 2x - 1 + x + 1
p = 6x - 5
b) p = 6x - 5 =31
6x - 5 = 31
6x = 36
x = 6

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
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.
