Find the unknown angles. please help

60°, 60°, 60°

Step-by-step explanation:

Since, two side of the given triangle are congruent l. Therefore, measures of both the interior angle will be equal.

By remote interior angle theorem:

120° = x + x

120° = 2x

120°/2 = x

60° = x

Third angle = 180° - 120° = 60°

Hence measure of all the three angles of the triangle are 60°, 60° and 60°

f(x) is going down by 4

step-by-step explanation:

(its either that or its going left by 4)

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;
