The equation y = 19.43x +609.077 is the equation of the regression line that predicts the number of people attending a county fa
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

The resistance, R of a wire varies directly as the length, l, and inversely as the diameter, d, squared. If R is 1.50ohms when l
tatyana61 [14]

Answer:

resistance is 1.5 ohms (1.5 Ω)

Step-by-step explanation:

R varies directly with l

R varies inversely with d^2

We can set-up a proportionality statement as shown below:

R=k\frac{l}{d^2}

Now, Given,

R = 1.50

l = 2

d = 1.5

We substitute and find k (the proportionality constant):

R=k\frac{l}{d^2}\\1.5=k\frac{2}{1.5^2}\\1.5=\frac{2k}{2.25}\\2k=1.5*2.25\\2k=3.375\\k=1.6875

Now, we will use this value of k to solve the problem.

Given,

l = 8

d = 3

and

k = 1.6875

We find R:

R=k\frac{l}{d^2}\\R=1.6875\frac{8}{3^2}\\R=\frac{1.6875*8}{9}\\R=1.5

The resistance is 1.5 ohms (1.5 Ω)
