If ∠I has a measure of 134∘, what is the measure of ∠A?
the angles are supplementary.

46

Step-by-step explanation:

angles that are supplementary add up to 180 so make equation x + 134 = 180

solve.

∠A = 46°

Step-by-step explanation:

Supplementary means that 2 or more angles add up to the sum of 180°, So we can say;

∠I + ∠A = 180

134 + ∠A = 180

∠A = 180 - 134

∠A = 46°

Therefore, we can conclude that the measure of ∠A is 46°.

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;
