Answer:
d. The histogram would be approximately bell-shaped, and the normal quantile plot would have data points have follow a straight-line pattern.
Step-by-step explanation:
Since the variable is normally distributed, the histogram of women's height should be approximately bell shaped (if the data was obtained form a random sample).
Again, the variable is normally distributed, therefore, the quantile plot should follow a straight line pattern (a diagonal line to be more precise).
The answer to the equation is 4x-5. This is called expanding brackets. So you have to do 2x times by 2 then u do 3x2 so whatever is on the inside u multiply it by the outside. If the answer is negative I must put a minus instead of plus
Final answer is 1,000 yup
Answer:
Number of workers = 20.
Step-by-step explanation:
p = - 4w^2 + 160 w
We need to find the value of w when p is a maximum.
We need to convert the equation to vertex form:
p = -4w^2 + 160w
p = -4(x^2 - 40w)
p = -4 [ (x - 20)^2 - 400]
p = -4(x - 20)^2 + 1600.
So the vertex is at (20 , 1600)
The maximum profit is 1600 and the number of workers = 20.
