Answer:

D

Step-by-step explanation:

Correlation coefficient is the leading coefficient of the line of best fit. We can estimate the slope by looking at the plots. The plots are moving in a positive slope so we can remove B and C and E.

We're left with slope of 1 and 0.5

We can faintly imagine the line of slope 1. It doesn't really fit. SO it is 0.5

Find the value of “X”

Answers

Answer:

x = 55

Step-by-step explanation:

A triangle equals 180 degrees, b will be used to find the missing angle.

21 + 34 + b = 180

55 + b = 180

subtract 55 from both sides

b = 125

A straight line is 180 degrees and the b, the missing angle, and x are supplementary angles so

125 + x = 180

x = 55

Find f(3) for f(x) = -5x – 2


​

Answers

Answer:

-17

Step-by-step explanation:

F(3) find f(x) = -5x - 2

As u can see instead of x inside the parentheses it's a 3, meaning we have to replace x with 3 in the equation

f(3) = -5x - 2

f(3) = -5(3) - 2

f(3) = -15 - 2

f(3) = -17

180 - 119 = 61

So, you’re answer would be 61 degrees. Hope that helped :)

the length of one side of a rectangle is p cm and width is 3(p-2) cm the perimeter is 44 cm find the length and width of rectangle​

Answers

Answer:

Length = 7cm, Width = 15cm

Step-by-step explanation:

Length = p

Width = 3(p-2)

          = 3p-6

Perimeter = length + width + length + width

                = p + 3p-6 + p + 3p-6

                = 8p-12

8p - 12 = 44

Isolate 8p.

8p = 44+12

    = 56

Find p.

p = 56 ÷ 8

p = 7

Length = 7cm

Width = 3(7)-6

          = 21-6

          = 15cm

there are 20% more goblins than wizards in magic club there are 120 goblins in magic club

Answers

Answer:

Final Answer: There are 100 wizards in the magic club

Step-by-step explanation:

Since this question is asking for how many wizards are in magic club, we can represent wizards with the variable "w"

w = wizards

Next, we know that there are 120 goblins and that there are 20% more goblins than wizards in magic club.

120 = w + 20%w

120 = w + 0.2w

(percentages are just the percent/100)

120 = 1.2w

1200 = 12w

100 = w
