Use the given data to find the minimum sample size required to estimate a population proportion or percentage. Margin of​ error:
Yakvenalex [24]

Answer: 112

Step-by-step explanation:

Given : Significance level : \alpha=1-0.95=0.05

Critical value: z_{\alpha/2}=1.96

Margin of error : E = 9%=0.09

The estimated proportion of caret : p =0.38

Now, the formula to find the sample size :-

n=p(1-p)(\dfrac{z_{\alpha/2}}{E})^2

i.e. n=(0.38)(1-0.38)(\dfrac{1.96}{0.09})^2

=111.738390123\approx112

Hence, the required minimum sample size = 112

tania brings 8.32 to the candy store. she wants to buy 21 jawbreakers does she have enough money? round your answer down to the
Neporo4naja [7]

Based on the information given regarding the equation, it can be noted that Tania doesn't have enough money.

<h3>How to solve an equation</h3>

Your information is incomplete. Therefore, an overview will be given. Let's assume that the price of a jawbreaker is 0.45.

Therefore, the cost of 21 jawbreakers will be:

= 21 × 0.45

= 9.45

In this case, the person has 8.32. Therefore, it can be noted that she doesn't have enough money.

1/4x + x = -3+ 1/2x, what is x?
USPshnik [31]

Answer:

x = -4

Step-by-step explanation:

Solve for x:

(5 x)/4 = x/2 - 3

Put each term in x/2 - 3 over the common denominator 2: x/2 - 3 = x/2 - 6/2:

(5 x)/4 = x/2 - 6/2

x/2 - 6/2 = (x - 6)/2:

(5 x)/4 = (x - 6)/2

Multiply both sides by 4:

(4×5 x)/4 = (4 (x - 6))/2

(4×5 x)/4 = 4/4×5 x = 5 x:

5 x = (4 (x - 6))/2

4/2 = (2×2)/2 = 2:

5 x = 2 (x - 6)

Expand out terms of the right hand side:

5 x = 2 x - 12

Subtract 2 x from both sides:

5 x - 2 x = (2 x - 2 x) - 12

5 x - 2 x = 3 x:

3 x = (2 x - 2 x) - 12

2 x - 2 x = 0:

3 x = -12

Divide both sides of 3 x = -12 by 3:

(3 x)/3 = (-12)/3

3/3 = 1:

x = (-12)/3

The gcd of -12 and 3 is 3, so (-12)/3 = (3 (-4))/(3×1) = 3/3×-4 = -4:

Answer:  x = -4
