Answer:
y + 3 = 2 (x - 4)
Step-by-step explanation:
y - y₁ = m (x - x₁)
substitute (4, -3) in for (x₁, y₁)
y - (-3) = m (x - 4)
substitute the slope (2) in for m (m=slope) and simplify (y - (-3)) to (y +3) because subtracting a negative is the same as adding a positive
y + 3 = 2 (x - 4)
and that's your final answer! hope this helped :)
Answer:
$3,250
Step-by-step explanation:
Find the perimeter of the yard ( the distance around the yard).
A rectangle has two sides of each dimension.
The perimeter is 20 + 20 + 45 + 45 = 130 feet.
Now multiply the total feet by the cost per foot:
130 feet x 25 per foot = $3,250 total.
Answer: yes it does

Answer:
a. SE = 0.403 mol
Step-by-step explanation:
The standard error of the mean, is the standard deviation of means of means.
It is calculated using,
We have the standard deviation to be
and the sample size is n=146.
We substitute the values to get:
We approximate to three decimal places to get:
