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
Answer:

Step-by-step explanation:

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 : 
a) The prior estimate of population proportion : p=0.08
Required sample size :-

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 :-

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