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:
x≤50
Step-by-step explanation:
100-3x≥-50
subtracting 100 at both side on inequality
-100+100-3x≥--50-100
-3x≥-150
Dividing both sides by 3
-3x/3≥-150/3
-x≥--50
Adding 50 on both sides
-x+50≥-50+50
-x+50≥0
Adding x on both sides
-x+x+50≥0+x
50≥x
so,
x≤50

Hey Kid!
Given:Length 14 cmWidth 7 cmHeigth 1.66 cm
Lateral area = 2lh + 2wh LA = 2(14cm)(1.66cm) + 2(7cm)(1.66cm) LA = 46.48 cm² + 23.24 cm² LA = 69.72 cm²
Surface area = 2(wl + hl + hw) SA = 2(7cm*14cm) + 2(1.66cm*14cm) + 2(1.66cm*7cm)SA = 196 cm² + 46.48 cm² + 23.24 cm²SA = 265.72 cm²
Hope this helps!

Answer:
63 metres
Step-by-step explanation:
A rectangle has 4 sides
2 of these sides are the lengths
The other 2 sides are the width
If the length of one side is 97 metres, the other side length must also be 97 metres
The two lengths then add together (97 + 97) to become 194 metres
Now we can use this information to calculate the width
320 (the total perimeter) subtract 194 (The total length) = 126 metres
This means that 126 metres is the total width
Because there are two sides which add up to the total width we divide 126 by 2
This allows us to get the measurement of the width
126 divided by 2 = 63 metres
