Answer:

x>-2

Step-by-step explanation:

first you want to get rid of all of the numbers on the left so you can only be left with 2x>-4 then you decide both sides by 2x because you only want to be left with one x and once you divide you will be left with x>-2

Answer:

Step-by-step explanation:

Given the system of equation

y=1/3x-2

y=-3x – 12

Since both equations are y values, we will equate then=m to each other as shown;

1/3x - 2 = -3x - 12

x/3 + 3x = -12 + 2

(x+9x)/3 = -10

x+9x = -30

10x = -30

x = -30/10

x = -3

Substitute x = 3 into equation 1;

From 1: y=1/3x-2

y=1/3(3)-2

y = 1 - 2

y = -1

<em>Hence the required solution (x, y) is (-3, -1)</em>

Yes. I don't understand how to explain it but it is yes. I will give a example to help explain to see if it will help. If a stick is 8 inches the storage container is 7 and has a diameter of 2+ it will fight the two inches adds 1 inch to the case if you are putting something diagonally.

The random variable x represents the number of computers that families have along with the corresponding probabilities. Find the

Charra [1.4K]

The value of the Mean & Standard deviation is 1.30 and 1.18.

According to the statement

we have a given that the random variable x represents the number of computers that families have along with the corresponding probabilities.

And we have to find the mean and standard deviation from the given data which is related to the probabilities values

So, according to the given data

The formula to compute the mean is:

Mean = summation [x*p(x)]

Compute the mean as follows:

Mean = summation [x*p(x)]

Mean = summation [0*0.49 + 1* 0.05 + 2*0.32 + 3*0.07 + 4*0.07]

Mean = 0 +0.05 + 0.64 + 0.21 + 0.28

Mean = 1.18

The mean of the random variable x is 1.18.

And after calculating the variance from the formula get

The value of standard deviation is 1.30

So, The value of the Mean & Standard deviation is 1.30 and 1.18.
