Answer:

41/10 or 4.1

Step-by-step explanation:

To find the mean of a set of numbers, you add all the numbers together then, divide it by the number of numbers. So,

1+2+10+6+4+4+6+3+1+4=41

There are 10 numbers. So we do 41/10.

This is equal to 4.1

A scientist is interested in the effect of time spent with parents and number of hours

gladu [14]

Answer: If X = 5, z=<u>-3</u>

If X = 37, z= <u>3.4</u>

Step-by-step explanation:

We know that the formula to find the z-score for any random variable x is given by :-

$z=\dfrac{x-\mu}{\sigma}$

, where $\mu$ = Population mean

$\sigma$ = Population standard deviation.

As per given , we have

$\mu=20\\\\\sigma=5$

Then , the z-score for x =5

$z=\dfrac{5-20}{5}=\dfrac{-15}{5}=-3$

i.e. If X = 5, z=<u>-3</u>

When x =37,then $z=\dfrac{37-20}{5}=\dfrac{17}{5}=3.4$

i.e. If X = 37, z= <u>3.4</u>

a rabbit's fur grows at a rate of 5/2 per month. How many months will it take for the rabbit's fur to grow 15/4 inches

UkoKoshka [18]

The answer is 1.5 months

explanation:

5/2 = 2.5

15/4 = 3.75

2.5 per month

3.75 per x months

x = (3.75×1)/2.5

x = 3.75/2.5

x = 3/2 = 1.5 months

1) write a system on equations with the solution (2, -3). Work the problem out using the substitution method

solmaris [256]

The system of the equations that have the solution of (2, -3) are given below.

3x + 2y = 0 and 3y = 2x - 13

<h3>What is the linear system?</h3>

A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.

Write a system of equations with the solution (2, -3).

From a single point, an infinite number of lines pass through this point.

Let one line is passing through the origin. Then the equation of the line will be

$\rm y = \dfrac{-3}{2} (x)\\\\y = -1.5x$

And the other line is perpendicular to the line which is passing through the origin and a point (2, -3).

$\rm y = \dfrac{2}{3} x + c$

Then this line also passes through a point (2, -3). Then the value of c will be

$\rm -3 = \dfrac{2}{3} \times 2 + c\\\\c \ \ = -13$

Then the equation of the line will be

3y = 2x -13
