The length, l, that a spring is stretched varies directly as the amount of force, F, applied to the end of the spring. When a fo

Elina [12.6K]

Answer:

C. 4.5 inches

Step-by-step explanation:

Given the following data;

Force, F = 10 pounds

Extension, e = 3 inches

First of all, we would determine the spring constant (k) using the following formula;

Force = spring constant * extension

10 = spring constant * 3

Spring constant = 10/3

Spring constant = 3.33 pounds per inches.

Next, we would find the extension of the spring when a force of 15 pounds is applied;

F = ke

15 = 3.33 * e

Extension, e = 15/3.33

Extension, e = 4.5 inches.

Softa [21]

Answer:

Probability to pick 4 tiles which spell CATS will be $\frac{1}{70}$ .

Step-by-step explanation:

We have 8 scrabble tiles A, B, C, D, R, S, T, U in a bag.

Probability to pick 4 tiles C, T, A, and S out of 8 tiles = $^{8}C_{4}$

= $\frac{8!}{4!(8-4)!}$

= $\frac{8!}{4!\times 4!}$

= $\frac{8\times 7\times 6\times 5\times4!}{4!\times 4!}$

= $\frac{1680}{24}$

= 70

So we can choose C, T, A and S tiles in 70 different ways but the probability to pick 4 tiles which spell CATS will be

= $\frac{1}{70}$

Therefore, probability to pick 4 tiles which spell CATS will be $\frac{1}{70}$ .
