Juan divided 126 ounces of orange juice evenly among 7 large cups. Natalie divided 168 ounces of pineapple juice evenly among 8 large cups. Juan and Natalie poured one cup of orange juice and one cup of pineapple juice into a container. Which equation could be used to solve for n, the number of ounces of juice in the container? n=126÷7−168÷8 n = 126 × 7 + 168 × 8

n = 294 ÷ 15

n = 126 ÷ 7 + 168 ÷ 8

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.

step-by-step explanation:

table 3 represents a direct variation function. : )

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;
