12 this is because my number for sports is 12 and i just need to answer a ? for point thanks have a good day
V=(π)(r^2)(h)
π=3
r=half of the diameter=4
h=12
V=(3)(4^2)(12)
= (3)(16)(12)
= 576 cm cubed

Given:
population mean, μ =135
population standard deviation, σ = 15
sample size, n = 19
Assume a large population, say > 100,
we can reasonably assume a normal distribution, and a relatively small sample.
The use of the generally simpler formula is justified.
Estimate of sample mean

Estimate of sample standard deviation


to 5 decimal places.
Thus, using the normal probability table,





Therefore
The probability that the mean weight is between 125 and 130 lbs
P(125<X<130)=0.0731166-0.0018308
=
0.0712858
Answer:
<u>$239.68</u>
Step-by-step explanation:
<u>Given</u>
- Cost = $224
- Sales Tax = 7%
<u>Solving</u>
- Cost w/ Tax = Cost (1 + Tax)
- Cost w/ Tax = 224 (1 + 0.07)
- Cost w/ Tax = 224 * 1.07
- Cost w/ Tax = <u>$239.68</u>
