Answer:

$m = -\frac{194}{3}$

Step-by-step explanation:

I'm assuming you are trying to find m. In order to do so, you need to get m on one side.

Before doing that let's multiple -2 and -3m by $\frac{4}{3}$

$256=-\frac{8}{3} - 4m$

add $-\frac{8}{3}$ to both sides

$258\frac{2}{3}=-4m$

I would get rid of the fraction so I'd multiply both sides by $\frac{3}{1}$

$\frac{776}{3}*3 = 4m*3$

$776=-12m$

divide both sides by -12m

$m = -\frac{776}{12}$

which can be simplified to

$m = -\frac{194}{3}$

ALL UNLESS THAT $\frac{4}{3}$ IS A POWER

Does anyone know how many ways you can make 16 and 19 on a grid

sasho [114]

You can look for the number 16 on the x-axis. (bottom line) and put a finger there. Then, look for 19 on the y -axis (left line) and put a finger there. Trace your left finger to the right and your right hand up until they meet. That is (16,19)

Can someone please help me with this ASAP‼️ Thank You

Let x = cost of the dishwasher.

The amounts the children are paying are:

Mark =20% = 1/5, so 1/5x

Sorin = 75

Raymond = 1/4x

Stephanie = 75

Kristin = 1/3x

Add them together:

x = 1/5x + 1/4x + 1/3x + 75 + 75

x - ( 1/5x + 1/4x + 1/3x ) = 150

Rewrite fractions with common denominator:

x - ( 12/60x + 15/60x + 20/60x ) = 150

60/60x - 47/60x = 150

13/60x = 150

x = 150/1 • 60/13

x = 9000/13

x = 692.31

The total cost of the dishwasher is $692.31

Now calculate the amount each child pays:

Mark = 1/5 x = 692.31/ 5 = $138.46

Sorin = $75.00

Raymond = 1/4 x = 692.31 / 4 = $173.08

Stephanie = $75.00

Kristin = 1/3 x = 692.31 / 3 = $230.77

A = a+b+c / 3

IgorLugansk [536]

The equation given in the question is

<span>A = a+b+c / 3
3A = a + b + c
3A - a - c = b

From the above deduction, it can be easily concluded that the correct option among all the options that are given in the question is the first option or option "A". I hope that this is the answer that has actually come to your desired help.</span>

Use the number line determine the absolute value. enter the value, as mixed numbers in the simplest form, in the box.

vitfil [10]

The absolute value of -1/3 is 1/3. I guess by using the number line you move 2(1/3) to the right from the point -1/3

he mean age of bus drivers in Chicago is greater than 54.4 years. If a hypothesis test is performed, how should you interpret a

Natalka [10]

Answer:

There is not sufficient evidence to support the claim μ > 54.4.

Step-by-step explanation:

1) Previous concepts

A hypothesis is defined as "a speculation or theory based on insufficient evidence that lends itself to further testing and experimentation. With further testing, a hypothesis can usually be proven true or false".

The null hypothesis is defined as "a hypothesis that says there is no statistical significance between the two variables in the hypothesis. It is the hypothesis that the researcher is trying to disprove".

The alternative hypothesis is "just the inverse, or opposite, of the null hypothesis. It is the hypothesis that researcher is trying to prove".

2) Solution to the problem

On this case we want to test is $\mu>54.4$ and the system of hypothesi on this case are:

Null Hypothesis: $\mu \leq 54.4$

Alternative hypothesis: $\mu >54.4$

On this case is our decision is FAILS to reject the null hypothesis then we can conclude that we don't have enough evidence to support the claim at the significance level provided. So the correct conclusion would be:

There is not sufficient evidence to support the claim μ > 54.4.
