So first in a separate sheet of paper you have to look for how many members of fam and friends does Kimberly have. Then write down the amount of money she has in total.
Then subtract 120-36 cause she buys the book.
Which equals. 84
Then you have to subtract 84 from what I said at the beginning

PLEASE HELPPPPP!!!! (answer in decimal)

Answer:

$\approx 0.482659$

Step-by-step explanation:

The experimental probability is the chance of an event happening based on data, or rather the experiment results, and not on a theoretical calculation. In essence, a theoretical calculation can be described by the following formula:

$\frac{desired}{total}$

However, the experimental probability can be described with the following formula:

$\frac{number\ of\ desired\ outcomes}{number\ of \ trials}$

The number of trials is the sum of the number of outcomes. In this case, the desired outcome is tails. Therefore, the experimental probability can be described using the following formula:

$\frac{tails}{total}$

One can also rewrite the formula as the following. This is because the total is the sum of the number of the two outcomes:

$\frac{tails}{heads+tails}$

Substitute,

$\frac{167}{167+179}$

Simplify,

$\frac{167}{346}$

Rewrite as a decimal:

$\approx 0.482659$

Part 1:

Gnom [1K]

P = 2(L + W)
L = 4/3W

P = 2(4/3W + W) <=== part 1 is D

when P = 28
28 = 2(4/3W + W)
28/2 = 4/3W + 3/3W
14 = 7/3W
14 / (7/3) = W
14 * 3/7 = W
42/7 = W
6 = W....width is 6 inches

L = 4/3W
L = 4/3(6)
L = 24/3
L = 8....length is 8 inches

A = L * W
A = 8 * 6
A = 48 in^2 <==== part 2
