I think the answer is a=7b*9/2=31.5M
because the x values are identical the radius would be found by subtracting the y values.
6-2 = 4
the radius is 4
Answer:
The sample proportion is 0.36635
Step-by-step explanation:
A confidence interval has two bounds, a lower bound and an upper bound.
The sample proportion is the halfway point betwen those two bounds, that is, the sum of those bounds divided by 2.
In this problem, we have that:
Lower bound: 0.2931
Upper bound: 0.4396
What is the sample proportion?
(0.2931 + 0.4396)/2 = 0.36635
The sample proportion is 0.36635
I think that it's B, y = -x - 7 because first you'd subtract y to get it on the other side then add x and then you'd need to make the y positive so you would divide x + 7 by -1 and that would make it y = -x - 7.
Multiplying each side by 3/4, we get (3/4)V=pir^3. Dividing both sides by pi, we then get r^3=(3/4)V/pi
For the second part, we get that 381.51=(4/3)πr^3, so plugging 381.51 into the equation above we get (3/4)(381.51)/pi=around 91, and r= the cube root of r^3, which would equal around 4.5 here
