atroni [7]

Answer:

1,114 people

Step-by-step explanation:

The equation y=19.43x+609.077 is the equation of the regression line that predicts the number of people attending a county fair, where x is the number of years after 2000.

To find the number of people that are expected to attend the fair in 2026, we determine how many years have passed and substitute into the equation.

From 2000 to 2026,

2026-2000=26yrs

have passed.

The expected number who will attend the fair in 2026 is

y=19.43*26+609.077

y=1114.26

To the nearest whole number 1,114 people will attend in 2026

One side of a triangle is twice as long as a second side. The third
natta225 [31]

Answer:

The longest possible values of the other two sides are 7 ft  and 14 ft

Step-by-step explanation:

Let one side of the triangle be x and the other, 2x

Perimeter of a triangle = sum of all sides; i.e x+2x+33

Therefore, x+2x+12=33

Solve for x;

3x=33-12

3x=21

Divide both sides by 3; x=21/3

therefore, x=7 and

2x= (2*7) = 14

The longest possible values of the other two sides are 7 ft  and 14 ft

Given:

L = W - 4

P = 2L + 2W

We can substitute 2L for 2(W - 4) = 2W - 8

So:

2W - 8 + 2W = P

P = 4W - 8

Answer is 4. 4W-8
