Answer:
4t^3-t-4
Step-by-step explanation:
(-3t^3-5t)+(7t^3+4t-4)
Combine like terms
-3t^3+7t^3 +4t -5t-4
4t^3 -t -4
Answer: a. 374.4321
Step-by-step explanation:
Taking the central limit theorem(number of samples is large) into consideration, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/(σ/√n)
Where
x = annual sales per square foot .
µ = mean annual sales per square foot
σ = standard deviation
n = number of samples
From the information given,
µ = $370
σ = $38.54
n = 64
The probability value is 18/100 = 0.18
Looking at the normal distribution table, the z score corresponding to the probability value is - 0.92
Therefore,
- 0.92 = (x - 370)/(38.54/√64)
x - 370 = - 0.9 × 4.8175 = 4.33575
x = 370 + 4.4321 = $374.4321

Answer:
c.
Step-by-step explanation:
just guessed it
Answer:
The slope of a straight line equals the change in the value on the <u>Vertical</u> axis <u>Divided</u> by the change in the value of the other axis measured between any two points on the line.
Step-by-step explanation:
Consider the provided information.
The slope of a straight line can be calculated as:
Where, Rise is the the change in the value on the vertical axis which is divided by the Run. Run is the change in the value of the other axis.
Therefore, the complete sentence is:
The slope of a straight line equals the change in the value on the <u>Vertical</u> axis <u>Divided</u> by the change in the value of the other axis measured between any two points on the line.
