Answer:
The fencing will cost $330.09
Step-by-step explanation:
First we have to calculate the perimeter of the semicircle for that we use the following formula:
d = diameter = 29ft
s = semicircle
π = 3.14
s = d * 1/2 * π
we replace the values that we know
s = 29ft * 1/2 * 3.14
s = 45.53ft
Now we multiply the number of feet by the price of what comes out 1 foot of fence
45.53 * $7.25 = 330.0925
Round to the nearest hundredth
$330.0925 = $330.09

Step-by-step explanation:
G(3)= 6+9-2=13
Answer:
y-3x-9=0
Step-by-step explanation:
(x1,y1)=(-3,0)and (x2,y2)=(-2,3)
Now,
y-y1=(y2-y1)/(x2-x1) (x-x1)
y-0=3-0/-2-(-3) (x-(-3))
y-0=3/1 (x+3)
y=3x+9
y-3x-9=0
there are 10 girls if the whole class is 70% and the boy's are 62% the the girls are 8%
Answer: p = 0.73
Step-by-step explanation:
Given that,
73% of the audience was under 20 years old :
so, probability (p) = 0.73
n = 146
Mean of the distribution of sample proportion = ?
According to central limit theorem,
np(1-p) ≥ 10
146 × 0.73(0.27) ≥ 10
28.77 ≥ 10
∴ Central limit theorem assumes that the sample distribution of the sample proportion is normally distributed.
Hence, the mean of the distribution of sample proportion:
μ = p = 0.73
