A sociologists was investigating the ages of grandparents of high school students. From a random sample of 10high school students, the sociologist collected data on the current ages, in years, of the students' maternal grandparents. A. One of the sociologist's research questions was about the mean difference in age without regard to which grandparent is older. The interval constructed in part (a) does not address such a question. Based on the sample of high school students, give the value of the point estimate for the mean difference in age that could be used to address the sociologist's question.

What is the coefficient of the variable in the expression 4 − 3x − 7 + 6?

Answers

Answer:

the coefficient of the variable in the given expression is, -3

Step-by-step explanation:

Coefficient states that a number which is used to multiply a variable.

For example:

here, y is the variable and 4 is the coefficient.

As per the statement:

Given the expression:

$4-3x-7+6$

Here, x is the variable

By definition of coefficient, we have;

⇒-3 is the coefficient

Therefore, the coefficient of the variable in the given expression is, -3

the coefficient of the variable in the expression 4-3x-7+6 is 3

Is the ordered pair (–8, –7) a solution to the equation 3x + 10 = 2y? Show your work.

Answers

Answer:

yes

Step-by-step explanation:

Substitute x = - 8 and y = - 7 into the equation

If both sides are equal then (- 8, - 7) is a solution

left side = 3x + 10 = 3(- 8) + 10 = - 24 + 10 = - 14

right side = 2y = 2(- 7) = - 14

Since both sides are equal then (- 8, - 7) is a solution to the equation

Final answer:

The ordered pair (-8, -7) is a solution to the equation 3x + 10 = 2y. This is determined by substituting the values of the ordered pair into the given equation leading to -14 on both sides of the equation.

Explanation:

To determine if the ordered pair (-8, -7) is a solution to the equation 3x + 10 = 2y, we can substitute -8 for x and -7 for y in the equation.

This would result in 3*(-8) + 10 = 2*(-7), which simplifies to -24 + 10 = -14. So the left side of the equation equals -14, and the right side of the equation equals -14 as well. Because both sides equal the same value, the ordered pair (-8, -7)is a solution to the given equation.
