The Ferris wheel shown makes 16 revolutions per ride. How far
gizmo_the_mogwai [7]

Answer:The diameter of the Ferris wheel in the image is 63 feet, and so the circumference is equal to C=πd=63π C = π d = 63 π feet. So the distance traveled in one ride (12 revolutions) is 12C=12⋅63π=756π≈2375.044 12 C = 12 ⋅ 63 π = 756 π ≈ 2375.044 feet.

On a school bus, the female teacher sitting in front of me asked if I passed gas, why did she ask me that out of nowhere and whi
kobusy [5.1K]

Answer: She was buggin'

Step-by-step explanation:

If you divide  <u>the fact that she's a teacher</u>

                      kids can smell sometimes <u>       </u>

Logically you would get: maybe she thought she smelled something

But when you apply the 'mind your own business rule, it cancels out any chance of her turning around to ask you that

             so you're answer is: she was buggin'

Other possible answers:

"No that's just your upper lip sis"

"Did you?"

*rolls eyes and ignores the question all together

The diameter of holes for a cable harness is known to have a normal distribution with σ = 0.01 inches. A random sample of size 1
Rama09 [41]

Answer: (1.4964, 1.5126)

Step-by-step explanation:

We know that the confidence interval for population mean is given by :-

\overline{x}\ \pm z*\dfrac{\sigma}{\sqrt{n}}

, where {\sigma= population standard deviation.

n= sample size

\overline{x} = Sample mean

As per given , we have

σ = 0.01 inches

n= 10

\overline{x}=1.5045

Also, the critical value for 99% confidence interval = z*=2.576 [From x-value table.]

[Significance level =1-0.99=0.01 and z_{\alpha/2}\ at\ \alpha=0.01 is 2.576.]

Then, the 99% two-sided confidence interval on the mean hole diameter will be :-

1.5045\ \pm (2.576)\dfrac{0.01}{\sqrt{10}}\\\\\approx1.5045\pm(2.576)(0.00316)=1.5045\pm0.00814016=(1.5045-0.00814016,\ 1.5045+0.00814016)\\\\=(1.49635984,\ 1.51264016)\approx(1.4964,\ 1.5126)

Hence, the required confidence interval = (1.4964, 1.5126)
