Answer:
22 in^2
Step-by-step explanation:
2*7 = 14
4*2 = 8
14 + 8 = 22
hope this helped :)
Y equals 3x-3 is the answer
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
So a diameter is twice the radius
The formula is:
V = π(r^2)(h/3)
the half of 300 is 150, so the radius is 150
V = π(150^2)(150/3)
V = π(22500)(50)
V is about <span>3534291.74</span>
Answer:
2.22 km
Step-by-step explanation:
Assuming initially both were at the same point ...
Distance from Rico = 5.98 km.
Distance from Josh = 8.2 km in the same direction.
If they were going in the same direction, then the final distance between the two can be written as follows:
d = 8.2 - 5.98 = 2.22 km
After 20 minutes, Rico and Josh were 2.22 km away. of distance between them.
