First find 30% of 248.

0.3 * 248 = 74.4

Now add it:

74.4 + 248 = 322.4

So our answer is £322.40

What is a linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

We have:

0.1x + 0.25y = 19.9 and

x + y = 100

Let x = number of dimes

y = number of quarters

After solving the above system of equations by substitution method.

$\rm \dfrac{398-5y}{2}+y=100$

y = 66

$\rm x=\dfrac{398-5\cdot \:66}{2}$

x = 34

Thus, the statement first, and the statement second are correct because the number of dimes is 34, and the number of quarters is 66

Jamey says she only has 30% of her book to go before she finishes it. she has read 147 pages so far

Lubov Fominskaja [6]

Let's just change your problem to 147 of 30%

"Of" is always equaling to multiplication (×)

Now, it would be easier to simplify

30% (147)
30% ÷ 100 = 0.3
0.3(147)
Now, we get to your answer which might be 44.1

Find the midpoint of the segment between the points (8,-10) and (-10,-8)

Delvig [45]

Answer:

(-1, -9)

Step-by-step explanation:

Recall that for 2 points (x1, y1) and (x2,y2)

the midpoints are given by

x ordinate = $\frac{x1+x2}{2}$

y ordinate = $\frac{y1+y2}{2}$

In our case x1 = 8, y1 = -10, x2 = -10, y2=-8

x ordinate = $\frac{x1+x2}{2}$ = [8 + (-10) ] / 2 = -1

y ordinate = $\frac{y1+y2}{2}$ = [-10 + (-8) ] / 2 = -9

hence midpoint is (-1, -9)

Evgesh-ka [11]

Answer:

Hello your question has some missing part below is the missing part

The mean hours per week and standard deviations for middle management who had been with the organizations for approximately the same length of time were: Baltimore facility, Burlington facility Mean 52.5 Mean 39.7

Standard deviation 19.7 Standard Deviation 8.9Using this data, complete the following:

State your hypothesis and conduct a hypothesis testing using a significance of 0.10.

answer : We will reject the Null hypothesis

Step-by-step explanation:

μ1 = mean working hours for Baltimore facility

μ2 = mean working hours for Burlington facility

Hence the Hypothesis are :

H0 : μ1 = μ2

Ha : μ1 > μ2

<em>Next: Conduct a hypothesis testing </em>

we will apply Z - testing attached below is the hypothesis testing

n1 = 145 , X1 = 52.5 , δ1 = 19.7 ( Baltimore )

n2 = 128, X2 = 39.7 , δ2 = 8.9 ( Burlington )
