Amos is painting his room . he needs 1/4 of a gallon to paint all four walls . how much paint will he need for each of his 4 walls if he uses the same amount of paint on each .

he needs  1/4 gallon total

4 walls so need to divide 1/4 x 4

1/4 / 4/1 = 1/4 * 1/4 = 1/16 gallon on each wall

He needs of gallon to paint each wall.

Step-by-step explanation:

Given :  He needs 1/4 of a gallon to paint all four walls .

To Find : How much paint will he need for each of his 4 walls if he uses the same amount of paint on each .

Solution:

He needs 1/4 of a gallon to paint all four walls .

He need paint to color 1 wall =

                                               =

Hence he needs of gallon to paint each wall.

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;

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a
