In accounting, the acid-test ratio, or quick ratio, is one way to measure a company's liquidity, or how well equipped it is to pay off debts in cash.
the quick ratio, qqq, is calculated using the formula q = \dfrac{ca-i - p}{cl}q=
cl
ca−i−p

q, equals, start fraction, c, a, minus, i, minus, p, divided by, c, l, end fraction, where cacac, a is the value of the company's current assets, iii is inventory, ppp is prepaid expenses, and clclc, l is current liabilities.
rearrange the formula to solve for current assets (ca)(ca)left parenthesis, c, a, right parenthesis.

b

step-by-step explanation:

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls

85.560%

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560
