A formula for 8 bottles of window cleaner calls for 6 cups of rubbing alcohol, 2 and one-fourth gallons of water, and 1 and one-half cups of ammonia. How many quarts of rubbing alcohol would the formula call for if a factory-made 1,280 bottles for stores to sell to customers? 24 quarts 48 quarts 240 quarts 480 quarts

240 quarts

Step-by-step explanation:

To make 8 bottles of window cleaner, we need:

Rubbing alcohol = 6 cups

Gallons of water= 2 1/4 gallons of water

Ammonia = 1 1/2 cups

We are asked to find out how many quarts of rubbing alcohol would the formula call for if a factory-made 1,280 bottles for stores to sell to customers.

Step 1

Find how many cups of alcohol is need to make 1,280 factory made bottles

If 8 bottle of window cleaner = 6 cups of alcohol

1280 factory made bottles =

We cross multiply

= (1280 × 6) ÷ 8

= 7680 ÷ 8

= 960 cups of alcohol.

Step 2

The question specify that they wanted to know the NUMBER OF QUARTS of rubbing alcohol needed

One quart of a cup = 1/4 of the cup

Therefore, the number of quarts of 960 cups of rubbing alcohol =

960 × 1/4 = 240 quarts

Therefore, the number of quarts of rubbing alcohol that the formula call would for if a factory-made 1,280 bottles for stores to sell to customers is 240 quarts.

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
