How to solve for 4(m - 2 ) = 24

tino4ka555 [31]

4(m - 2 ) = 24

Divide both sides by 4

m - 2 = 8

add 2 to both sides

m = 10

Hope this helps! ;)

A bank loaned out 16,000 $, part of it at the rate of 6% per year and the rest at 14% per year. If the interest received in on

MakcuM [25]

Answer:

This question requires a comparison between two different variables 6% and 16% values. If we let x=$ loaned on 6% loans and y=$ loaned on 16% loans, then we can relate two equations.

0.06x + 0.16y = $1500 --> referencing the interest earned from each percentage loaned.

x + y = $16000 --> referencing the total amount of money loaned out.

Rearrange either equation and substitute for a value in the other equation or use elimination to determine each individual variable.

Question 3 of 10 * - 3 is a factor of P(x) =*? – 73? + 158-9 O A. True O B. False

Elina [12.6K]

Given,

The expression is,

$P(x)=x^3-7x^2+15x-9$

If x- 3 is the factor of the given polynomial function, then on substituting the value of x = 3 in the polynomial function, it become zero.

Thus subsituting the value of x in the polynomial,

$\begin{gathered} P(3)=3^3-7\times3^2+15\times3-9 \\ =27-7\times9+45-9 \\ =27+45-63-9 \\ =72-72 \\ =0 \end{gathered}$

Here, the obtained value of polynomial is 0.

Hence, x-3 is a factor of the given polynomial.

Thus, option A(true) is correct.

Answer:

<h3>The standard error of the mean is <u>15</u></h3>

Step-by-step explanation:

Given that a simple random sample of 64 observations was taken from a large population.

Hence it can be written as n=64

The population standard deviation is 120.

It can be written as $\sigma_{\overline{X}}=120$

The sample mean was determined to be 320.

It can be written as $\overline{X}=\mu =320$

<h3>To find the standard error of the mean :</h3>

The formula for the standard error of the mean is given by

$\sigma_{\overline{X}}=\frac{\sigma}{\sqrt{n}}$

Now substitute the values in the formula we get

$\sigma_{\overline{X}}=\frac{120}{\sqrt{64}}$

$=\frac{120}{8}$

$=15$

$\sigma_{\overline{X}}=15$

<h3>∴ The standard error of the mean is 15</h3>
