Question:

Which situation describes the best example of rotational motion?

A. Craig sent the pool ball spinning toward the side pocket.

B. The skater repeated the figure eight on the ice.

C. Sara spun the dreidel on its pointed end.

D. The mouse ran in circles around the mousetrap.

Answer :

C

Explanation:

It's C, because it is spinning. It can't be D because it's going in a circle, not spinning. it can't be A because it doesn't really make sense. It can't be B because the Skater is repeating, not rotating. So the only logical answer is C.

A political candidate has asked his/her assistant to conduct a poll to determine the percentage of people in the community that

Alexxandr [17]

Answer:

The size of the sample needed = 67.65

Explanation:

Given that :

The margin of error = 10% = 0.10

The confidence level = 90% = 0.90

Level of significance = 1 - 0.90 = 0.10

At ∝ = 0.10

$Z_{\alpha/2}= Z_{0.10/2} = 1.645$

Since the proportion of people that supported him/her is not given, we assumed p = 0.50

The margin of error formula can be expressed as:

$M.O.E = Z_{\alpha/2} \times \sqrt{\dfrac{p(1-p)}{n}}$

$0.10 = 1.645 \times \sqrt{{\dfrac{0.5(1-0.5)}{n}$

Squaring both sides; we have:

$0.10^2 = 1.645^2 \times {\dfrac{0.5(1-0.5)}{n}$

$0.01 = 2.706025 \times \dfrac{0.25}{n}$

$n= 2.706025 \times \dfrac{0.25}{0.01 }$

n = 67.65

Therefore, the required sample size = 67.65
