Answer:




Step-by-step explanation:
we are given

Calculation of A(4):
we can plug x=4

Since, this curve is below x-axis
so, the value of integral must be negative
and it is quarter of circle
so, we can find area of quarter circle
radius =4


Calculation of A(8):
we can plug x=8

we can break into two parts

now, we can find area and then combine them


Calculation of A(12):
we can plug x=12

we can break into two parts

now, we can find area and then combine them


Calculation of A(14):
we can plug x=14

we can break into two parts

now, we can find area and then combine them



Answer:
Sample size n = 1382
so correct option is D) 1382
Step-by-step explanation:
given data
confidence level = 99 %
margin of error = 3%
probability = 25 %
to find out
How large a sample size needed
solution
we know here P = 25 %
so 1 - P = 1 - 0.25
1 - P = 0.75
and we know E margin of error is 0.03 so value of Z for 99%
α = 1 - 99% = 1 - 0.99
α = 0.01
and
= 
= 0.005
so Z is here
= 2.576
so
sample size will be
Sample size n = 
put here value
Sample size n = (\frac{2.576}{0.03})^2 * 0.25 * 0.75
Sample size n = 1382
so correct option is D) 1382
29.98/24≈1.25
2.29-1.25= $1.04
Ok, so we know one point is (4,2) and the other is (-4, 0)
Slope: -2/-8 = 1/4
y ? 1/4x + b
0 = -1 + b
b = 1
y < 1/4x + 1
