First of all, half of 18 is 9, and if you divide 18 by 2.5, it results in 7.2. I hope this helps!

the regression equation y=-0.414 + 106.55 approximates the percent of people in an audience who finish watching a documentary, y
WARRIOR [948]

Answer:

<em><u>The answer is</u></em>: <u>59%</u>.

Step-by-step explanation:

To calculate the percentage of people who have seen the movie we start from: y = -0.414x + 106.55; and of x = 115; making the appropriate substitutions we would have left: y = -0.414 (115) + 106.55; y = -47.61 + 106.55; y = 58.94, which rounded to exceed 0.5 would be 59%.

<em><u>The answer is</u></em>: <u>59%</u>.

Nutka1998 [239]

Answer:

After 13 days (Rounded) If you dont round it's \frac{90}{7} or 12\frac{6}{7}

Step-by-step explanation:

Perry: 180 - 6x = 8x

180 - 6x + 6x = 8x + 6x

180 = 14x

180/14 = 14x/14

please ANSWER at least ONE question CORRECTLY FOR 8 POINTS &amp; ANSWER at least THREE CORRECTLY to be MARKED BRAINLIEST! (you d
4vir4ik [10]

Answer:

a. yes

b. no

c. no

d. no

e. yes

Step-by-step explanation:

Here, we want to answer yes or no for each of the numbers

a) Yes

If we compare with the general form

y = mx + b

m

is slope and b is y-intercept

so, 2 is slope and 3 is y intercept; so 3 in y-intercept is (0,3)

b. No

This is the point-slope form we are trying to

get

Evaluating this, we have that

y-3 = 2x - 6

y = 2x-6 + 3

y = 2x-3

c) NO

Just insert the values and check here

-1 = 2(5) + 3

it does not work

d) No

Substitute

-4 = 2(-5) + 3

e) Yes

This is the point-slope form

y + 3 = 2x + 6

y = 2x + 6-3 = 2x + 3

Kobotan [32]

Step-by-step explanation:

lets radius be r and height be h,

r+h=21 -----(1)

curved surface area

2×pi×r×h=616 -----(2)

use simultaneous eqn to solve for r and h.

total surface area of cylinder= 2×pi×r×h + 2×pi×r²

= ans if im not wrong
