The table shows the gallons filled in a pool overtime. complete the table. determine a unit rate for this situation.

Number of hours    1/8       1/4     1/2    5/8

Gallons filled          125      250    500   625

Step-by-step explanation:

Consider the provided table.

From the table it is given that, for 1/2 hours gallon filled in pool is 500.

This can be written as:

1/2 hours = 500 gallon

Multiply both the sides by 2.

1 hours = 1000 gallon

For 1/8 hours:

Divide both sides by 8.

1÷8 hours = 1000÷8 gallon

1/8 hours = 1000/8 gallon

1/8 hours = 125 gallon

For 1/4 hours:

Divide both sides by 4.

1÷4 hours = 1000÷4 gallon

1/4 hours = 1000/4 gallon

1/4 hours = 250 gallon

For 5/8 hours:

Multiply both the sides by 5/8

1×5/8 hours = 1000×5/8 gallon

5/8 hours = 125×5 gallon

5/8 hours = 625 gallon

Hence, the required table is:

Number of hours    1/8       1/4     1/2    5/8

Gallons filled          125      250    500   625

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;
