3 times the sum of 1/3 of a number and 8 is 11

1 answer:

8 0

Let the number be x.

1/3 of the number = (1/3)*x = x/3

Sum of it and 8 = (x/3) + 8

3 times the sum = 3*((x/3) + 8) = 11

3*((x/3) + 8) = 11

3*x/3 + 3*8 = 11

x + 24 = 11

x = 11 - 24

x = -13

The number is - 13.

I hope this helps.

Answer:

All values are identical.

Step-by-step explanation:

We are given the following in the question:

If the standard deviation of a set of data is zero.

Then, all the values in data are identical.

This can be shown as:

Let all the terms in data be x.

Formula:

$\text{Standard Deviation} = \sqrt{\displaystyle\frac{\sum (x_i -\bar{x})^2}{n}}$

where $x_i$ are data points, $\bar{x}$ is the mean and n is the number of observations.

$Mean = \displaystyle\frac{\text{Sum of all observations}}{\text{Total number of observation}}$

$Mean =\displaystyle\frac{nx}{n} = x$

Sum of squares of differences =

$\displaystyle\sum (x_i - x)^2 = 0$

$\sigma = \sqrt{\frac{0}{n}} = 0$

Thus, the correct answer is

All values are identical.

Jenna has a savings account invested in stocks and bonds. 20% of her savings is in bonds. If Jenna has $2,200 in bonds, how much

VladimirAG [237]

Answer: Her total savings are equal to $11,000.

Step-by-step explanation:

Hi, to answer this question we have to write an equation.

The total savings (x) multiplied by the percentage in bonds (in decimal form) must be equal to $2,200.

Mathematically speaking:

x (20/100) = 2,200

Solving for x:

x = 2,200/ 0.2

x = $11,000

Her total savings are equal to $11,000.
