A survey of 73 students found that 37% were in favor of raising tuition to pave new parking lots. The standard deviation of the sample proportion is 9.8%. How large a sample (to the nearest person) would be required to reduce this standard deviation to 4.7%?
Answers
Answer:
The value is [tex]n_2 = 317[/tex]
Step-by-step explanation:
From the question we are told that
The sample size is n = 73
The proportion that in favor of raising the tuition is [tex]\^{p} = 0.37[/tex]
The standard deviation is [tex]s_1 = 0.098[/tex]
The required standard deviation [tex]s_2 = 0.047[/tex]
Generally the requires standard deviation is mathematically represented as
[tex]s_2 = s_1 * \sqrt{\frac{n_1}{n_2} }[/tex]
=> [tex]\frac{s_2}{s_1} = \sqrt{\frac{n_1}{n_2} }[/tex]
=> [tex]\frac{n_1}{n_2} =[\frac{s_2}{s_1} ]^2[/tex]
=> [tex]\frac{73}{n_2} =[\frac{0.047}{0.098} ]^2[/tex]
=> [tex]\frac{73}{n_2} =0.2300[/tex]
=> [tex]n_2 = \frac{73}{0.2300}[/tex]
=> [tex]n_2 = 317[/tex]

the owner of an apple orchard ships apples in boxes that weigh 2 kilograms ( kg ) when empty. the average apple weighs 0.25 kg and the total weight of a box filled with apples is 12 kg. how many apples are packed in each box?
a. 14
b. 30
c. 40
d. 56
Answers
Given parameters:
Weight of box = 2kg
Average weight of an apple = 0.25kg
Total weight of box filled with apples = 12kg
Unknown:
Number of apples packed in each box = ?
Solution:
Since 1 apple weighs 0,25kg, let us find the weight of the apples in the box
Box + apples = 12kg
weight of box = 2kg
Weight of apples = 12kg - 2kg = 10kg
So;
0.25kg is the weight of 1 apple;
10kg of apples will equal [tex]\frac{10}{0.25}[/tex] = 40 apples
Therefore, 40 apples are packed in the box

Diego is buying shrimp and rice to make dinner. Shrimp
costs $6.20 per pound and rice costs $1.25 per pound.
Diego spent $10.55 buying shrimp and rice.
The relationship between pounds of shrimp s, pounds
of rice r, and the total cost is represented by the
equation 6.20s + 1.25r= 10.55.
Write an equation that makes it easy to find the number
of pounds of rice if we know the number of pounds of
shrimp purchased.
Answers
Answer:
r= (10.55−6.20s)
--------------------------
1.25
Step-by-step explanation:
Using the principle of subject of formula, we make number of pounds of rice, r the subject of the given equation. Hence, the equation would be r = (10.55 - 6.20s)/1.25
Given the expression :
6.20s + 1.25r = 10.55
Isolate 1.25r
1.25r = 10.55 - 6.20s
Divide both sides by 1.25 to isolate r
r = (10.55 - 6.20s)/1.25
Therefore, the required expression would be
r = (10.55 - 6.20s)/1.25

Answer:
x = 19
Step-by-step explanation:
the question tells you that the angle CBD is 90°.
so, that means that angle DBE and angle CBE add up to 90.
using this, you can make the following equation:
2x - 1 + 5x - 42 = 90
2x + 5x + -43 = 90
7x - 43 = 90
add 43 to both sides
7x = 90 + 43
7x = 133
x = 133/7
x = 19

Select the correct answer. Which number is a zero of h(x) = (x2 − 81)(x + 4)
A. 0
B. 4
C. 9
D. 81
Answers
Answer:
9 is a zero of h(x). C. Correct
Step-by-step explanation:
We want to find the zeros of the function
[tex]h(x) = (x^2 - 81)(x + 4)[/tex]
The zeros are the values of x that make h(x)=0, thus we need to solve the equation:
[tex](x^2- 81)(x + 4)=0[/tex]
Factoring:
[tex](x^2 - 81)=(x-9)(x+9)[/tex]
[tex](x-9)(x+9)(x + 4)=0[/tex]
This equation has 3 solutions:
x=9, x=-9, x=-4
A. 0 is not a zero of h(x). Incorrect
B. 4 is not a zero of h(x). Incorrect
C. 9 is one of the zeros of h(x) calculated above. Correct
D. 81 is not a zero of h(x). Incorrect
