Susan makes 5 fruit cups for the picnic. In each cup, she has 5 strawberries and 3 kiwi. Joanna uses the same number of total fr
evablogger [386]

she uses the same amount of fruit so Susan used 5 strawberries per cup ( 5*5 = 25 total strawberries) and 3 kiwi ( 3*5 = 15 total kiwis)

 25+15 = 40 total pieces of fruit.

Joanna made 4 cups with 8 strawberries each

8*4 =32

40-32 = 8 , so she can use 8 kiwis

8 kiwis / 4 cups = 2 kiwis per cup

In a prior sample of U.S. adults, the Center for Disease Control (CDC), found that 8% of the people in this sample had pinworm b
kow [346]

Answer: a) 453  b) 1537

Step-by-step explanation:

As per given , we have

Margin of error : E= 0.025

Critical value for 95% confidence interval : z_{\alpha/2}=1.96

a) The prior estimate of population proportion : p=0.08

Required sample size :-

n=p(1-p)(\dfrac{z_{\alpha/2}}{E})^2\\\\=0.08(1-0.08)(\dfrac{1.96}{0.025})^2\\\\=452.386816\approx453

The minimum sample size is 453 U.S. adults.

b) Since the prior estimate of population proportion is not available , so we take p= 0.5

Required sample size :-

n=0.5(1-0.5)(\dfrac{z_{\alpha/2}}{E})^2\\\\=0.25(\dfrac{1.96}{0.025})^2\\\\=1536.64\approx1537

The minimum sample size is 1537 U.S. adults.

If ||M and M6 = 4X - 15 and m7 = x + 30 then m 6 =​
TEA [102]

Answer:

<h2>15</h2>

Step-by-step explanation:

∠6 and ∠7 are Alternate Interior Angles.

The lines l and m are parallel, therefore ∠6 and ∠7 are congruent.

m∠6 = m∠7 → 4x - 15 = x + 30        <em>add 15 to both sides</em>

4x = x + 45          <em>subract x from both sides</em>

3x = 45            <em>divide both sides by 3</em>

x = 15
