Plug 10 in for y.

10=2x-2.5

Add 2.5 to both sides.

12.5=2x

Divide both sides by 2.

6.25=x

Hope this helps! :)

Your answer would be 6.25.

When finding the answer to this equation, you will insert 10 where 'y'' is in the equation. 10= 2x - 2.5. Then you want to have x alone on one side, so you need to add 2.5 to 10. 12.5= 2x. Once you did this, divide 12.5 by 2 and you have your answer. 12.5/2= 6.25

Suggest a fundamentally and conceptually different way that is always under the control of the researcher of making the margin o
SVEN [57.7K]

Step-by-step explanation:

First, we may wonder, what does the term <em>margin of error</em> mean? Put simply, the margin of error is a measure of the degree to which research results do not reflect the views of the total studied population. In other words, it tells readers how much confidence they should have in the results presented.

It has often been suggested that a fundamentally and conceptually effective way that is always under the control of the researcher of making the margin of error smaller is to<em> increase the sample size</em> of the research. This basically involves collecting more sample data which thus leads to a closer estimate of the view of the entire population.

A salesperson receives step commission on sales calculated as follows:
kykrilka [37]

Answer:

$2278.846

Step-by-step explanation:

Given the following commision steps :

8% on first $1000;

12% next $2000;

20% on sales above $3000

Recorded sales for a week :

Monday $1500.00

Tuesday $3000.00

Wednesday $ 970.00

Thursday $4563.81

Friday $2760.42

This assu es that commision is calculated after weekly sales:

Total:

(1500 + 3000 + 970 + 4563.81 + 2760.42)

= $12794.23

8% on first $1000

0.08 × $1000 = $80

12% of $2000 = $240

20% of $(12794.23 - 3000)

= 0.2 × 9794.23

= 1958.846

Total commision for the week :

$(80 + 240 + 1958.846)

= $2278.846

50 Points! find x and explain how you found it!
stepan [7]

To find the length of the side opposite the angle while knowing the hypotenuse we can use the sine function:

   sin(53) = (side opposite angle of 53 degrees) / hypotenuse

    sin(53) = x / 24

     x = 24 sin(53)

    x = 19.16

Hope that helped
