Answer:

x=-18

Step-by-step explanation;

1/2x=-9

(2)1/2x=-9(2)

Answer:

x = -18

Step-by-step explanation:

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other.

Multiply 2 to both sides:

(x/2) * 2 = (-9) * 2

x = -9 * 2

x = -18

x = -18 is your answer.

The table represents a function.

zavuch27 [327]

Answer:

The correct option is 3. The rate of change in the function $y=x-6$ is less than the rate of change of the function represented in the table.

Step-by-step explanation:

The given table represents a function.

Choose any two points from the table. The two points are (0,-5) and (2,1).

Slope of a line is

$m=\frac{y_2-y_1}{x_2-x_1}$

Slope of the function that is represented by the table, is

$m=\frac{1-(-5)}{2-0}=\frac{6}{2}=3$

Therefore the rate of change of function is 3.

The given function is

$y=x-6$

It is a slope intercept form of a line.

$y=mx+b$

Where m is the slope and b is y-intercept.

Therefore the slope of the given function is 1.

Since 1<3, therefore rate of change in the function $y=x-6$ is less than the rate of change of the function represented in the table. Option 3 is correct.

The range of values for the sample mean that fall within 1 standard error of the mean in a sampling distribution is M39 to M43.

marusya05 [52]

The question is incomplete! The complete question along with answer and explanation is provided below.

Question:

The range of values for the sample mean that fall within 1 standard error of the mean in a sampling distribution is M = 39 to M = 43. What Is the mean of the sampling distribution, and what is the standard error

a) mean = 41, standard error = 2

b) mean = 39 or 43, standard error = 2

c) mean = 41, standard error = 4

e) the mean and standard error are unknowns

Given Information:

Standard error = 1

Range of values = 39 to 43

Required Information:

Mean and standard error = ?

Answer:

Mean is 41 and Standard error is 2

Explanation:

We know that the mean and standard error are related as

s = μ + (1)ο

s = μ - (1)ο

43 = μ + (1)ο

39 = μ - (1)ο

option (a) satisfies the above equations

43 = 41 + (1)2

43 = 43

39 = 41 - (1)2

39 = 39

Therefore, the correct option is (a)

Mean is 41 and standard error is 2
