The mean of the values in a data set is c. If each of the values in the data set were multiplied by 6, what would be the mean of

oksian1 [2.3K]

Answer:

Mean of the data would be 6c

Step-by-step explanation:

<u>Rule to Remember:</u> Whenever each term of the data is multiplied by the same number, the new mean is previous mean multiplied by that number.

In this case, original value of mean was c. Each value of the data is multiplied with 6 so a result the new mean would be 6 times the original mean i.e. 6c

Let us consider that original values in the data set are x, y and z. Their mean would be:

$Mean=\frac{x+y+z}{3}$

If each value of the data is multiplied with 6, the new values would be 6x, 6y and 6z. The mean in this case will be:

$Mean=\frac{6x+6y+6z}{3}\\Mean=\frac{6(x+y+z)}{3}\\Mean=6\times\frac{x+y+z}{3}\\Mean=6c$

We can see from above that the new mean is 6 multiplied to the original mean.

Therefore, the answer to this question is 6c.

What's y=4x-2<br> 3x+2y=-4

vladimir1956 [14]

X=0
Y=-2

Multiply the top equation by -2 to get -2y=-8x+4

Isolate 2y on the bottom by subtracting 3x from both sides to get 2y = -4 - 3x

Add the two equations get 0=-11x so x = 0

Solve for y by plugging zero into one of the equations to get y=4(0)-2 to find the y = -2
y=4(0)-2

Shayla is balancing her checkbook. Which subset of real numbers best describes her balance?

vladimir1956 [14]

Money values are usually rounded to the nearest hundredth (2 decimal places).

Thus, this means that her balance can be whole or a terminating decimal to the nearest hundredth.

Therefore, the subset of real numbers that best describes her balance is the set of rational numbers.
