3. A triangle has angles described as follows: The measure of the first angle is four more than seven times a number,
the measure of the second angle is four less than the first, and the measure of the third angle is twice as large as the
first. What is the measure of each angle in degrees?

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3

idk

step-by-step explanation:

answer: the best estimate of the mean of the population = 14.

step-by-step explanation:

given: sheri surveyed eighty students, then generated three random samples of twenty-five student responses.

the sample mean=

⇒ the sample mean=

hence, the best estimate of the mean of the population = 14.
