Step-by-step explanation:
-18*1 = -18
Answer:
2.0
Step-by-step explanation:
x = age
y = average systolic blood pressure
x₁ = 40 years old, y₁ = 110 systolic blood pressure
x₂ = 50 years old, y₂ = 130 systolic blood pressure

∴ Slope of the regression line is 2.0
Answer:
(x - 3) is not a factor
Step-by-step explanation:
If (x - h) is a factor of f(x) then f(h) = 0
here
f(x) = x³ - 5x² - 4x + 6 , then
f(3) = 3³ - 5(3)² - 4(3) + 6 = 27 - 5(9) - 12 + 6 = 27 - 45 - 6 = - 24
since f(x) ≠ 0 then (x - 3) is not a factor of f(x)
Answer: The divers depth is 144.5 feet below sea level. Or -144.5 feet.
To find this answer, you have to plug in 4.5 into the given equation.
The steps will look like this. I changed 12 and 1/3 to 37/3
-200 + (37/3)(4.5)
-200 + 55.5
-144.5
This is the depth of the diver after 4.5 seconds.
6x^5 + 36x^2 + 24x =
6x(x^4 + 6x + 4) <==
