Answer:
a) We need a sample size of at least 2401.
b) We need a sample size of at least 1936.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of , and a confidence level of , we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of .
The margin of error is:
95% confidence level
So , z is the value of Z that has a pvalue of , so .
(a) you are unwilling to predict the proportion value at your school and
We use , which is when we are going to need the largest sample size.
So we need to find We need a sample size of at least 2401.
(b) you use the results from the surveyed school as a guideline.
Now the same calculation, just with . So
We need a sample size of at least 1936.

What is m
A. 56°
B. 68°
C. 112°
D. 124°
Answer:
I couldn't tell which angle you meant, so the two missing angles are Q = 56 and S = 68
Step-by-step explanation:
Q = 180 - 124
Q = 56
56 (angle Q) + 56 (angle R) = 112
S = 180 - 112
S = 68
A rectangular pyramid has a height of 10 meters. The base measures 8 meters in length and 12 meters in width. Two different triangular cross sections are formed through the vertex and perpendicular to the base. What is the difference in the areas of the cross sections? Enter your answer in the box.
_______m2
PLZ HELP
Answer:
The answer is 30 m²
Step-by-step explanation:
step 1
find the area of the first cross section
area1=b1*h/2
b1=8 m
h=10 m
area1=6*10/2------> 30 m²
step 2
find the area of the second cross section
area 2=b2*h/2
b2=12 m
h=10 m
area1=12*10/2------> 60 m²
step 3
find the difference in the areas of the cross sections
difference=60-30------> 30 m²

Solve and show your work for each question.
(a) What is 0. 36 expressed as a fraction in simplest form? (line over 36)
(b) What is 0.36 expressed as a fraction in simplest form? (line over 6)
(c) What is 0.36 expressed as a fraction in simplest form? (no line)
Answer:
I’m sorry if I’m wrong
Step-by-step explanation:
A) 0.36 with a line over both 36 means as a decimal the 36 repeats, so it would look like 0.363636
as a fraction it would be 36/99, divide both numbers by 9 to get 4/11
B) 0.36 with the line over the 6 means just the 6 repeats so it would look like 0.3666
as a fraction that would be 33/90 , divide both by 3 to get 11/30
C) 0.36 would be 36/100, divide both numbers by 4 to get 9/25

Answer:
Figure ABCD is translated 3 unit(s) right and 1 unit(s) up.
Step-by-step explanation:
Lets take the point C from the original figure and watch how it translates to it's prime point C' on the other figure. Start at point C and see how many units does it move right until it aligns with the point C', then from there how many points do you need to go up to reach exactly on the point C'. If done correctly, the answer would be: 3 units to the right and 1 unit up

Figure AA is a scale image of figure BB
Figure A maps to figure B with a scale factor of 1 1/2
Answer: x=3
Step-by-step explanation:
We know that the triangle got smaller. When you dilate by a scale factor of something, you multiply to make a number bigger or smaller. So x÷1.5= 2
x= 2x1.5
x= 3

Answer:
Formula of circumference: pie(use 3.14 or 22/7) x radius (half of diameter or already given radius) x 2
100 + 100 = 200.
Half of 50(diameter) is 25(new radius). 25(radius) x 3.14(pie) x 2(it always will be there when finding circumference) = 157.
200 + 157 is = 357.
357 is your answer.

A sign says that the price on all music equipment is 30% off the original price. you buy an electric guitar for the sale price of $315.
A-what is the original price?
B-How much money did you save off of the original price?
C-What percent of the original price is the sale price?
Answer:
Step-by-step explanation:
sale price = original price minus discount.
discount = original price * discount percent / 100.
let s represent the sale price.
let p represent the original price.
let d represent the discount.
let k represent the discount percent.
the above formulas become:
s = p - d
d = p * k/100
we know that s = 315.
we know that k = 30.
formulas become:
315 = p - d
d = p * 30/100
simplify these formulas to get:
315 = p - d
d = .3p
