Answer:

1. A

2. C

Step-by-step explanation:

Add all of the values together.

0.5 + 0.8 + 0.6 + 0.7 + 0.4 = 3

Find the average.

3 / 5 = 0.6

Add on the extra values and find the average to determine if it changes or not.

All of them change but A.

Therefore, the answer is A.

Mean:

Add all the values together.

5 + 10 + 12 + 10 + 8 + 3 = 48

Find the average.

48 / 6 = 8

Median:

Group the numbers from lowest to highest.

3, 5, 8, 10, 10, 12

Find the middle number.

8 & 10

The middle of 8 and 10 is 9.

Therefore, the median is 9.

Mode:

Find the most common number.

It is 10.

Therefore, the mode is 10.

Match your numbers in order with the choices.

It fits C.

Therefore, the answer is C.

Answer asap!!! which equation could be used to find the perimeter of a rectangle that has a width of 10 inches and a length of 2

Arlecino [84]

Answer:

d. p = 2*20 + 2*10

Step-by-step explanation:

You know to find the perimeter, just add side + side + side + side.

And two pairs of sides on a rectangle are congruent, so the missing side lengths based on the width and length, will be 20 & 10.

So add 20 + 20 + 10 + 10.

To simplify this, say 2*20 and 2*10. And then add them.

So it is D

What is the slope of a line that is perpendicular to the line whose equation is 3x+2y=6?

LekaFEV [45]

first, we can find the slope from the equation that is given buy solving the equation for y

3x+2y = 6

2y = 6-3x

y = 3-3/2x

y = -3/2x+3

now that the equation is in slope-intercept form, we can easily see that the slope of the given line is -3/2

perpendicular lines have slopes that are negative reciprocals, so we can just take the negative reciprocal of the slope we have

-3/2 → 3/2 → 2/3

the slope of the perpendicular line is 2/3

hope this helped

I really need help with this equation as soon as possible :D

viktelen [127]

The subtraction sign in front of the second set of parenthesis changes the signs on the terms inside those parenthesis. So this could be rewritten as $x-3x^4+2x^2+x^3-4x^6$ . None of the exponents on the x are the same, so we will just express it in terms of descending powers of x. $-4x^6-3x^4+x^3+2x^2+x$ . This is also the same as $4x^6+3x^4-x^3-2x^2-x$ if you don't like to start with a negative. Either one is correct.
