(-12 - 2i) + (2 + 2i)
= -12 - 2i + 2 + 2i
= -12 + 2 - 2i + 2i
= -10
Answer: -10
90(140/100)

Answer:
$1571
Step-by-step explanation:
If we assume that y is profit in dollars, the maximum value of y is revealed by a graph to be ...
ymax = $1571
The maximum profit the company can make is $1571 at a selling price of $45 each.
_____
The function can be written in vertex form as ...
y = -(x^2 -90x) -454
y = -(x^2 -90x +45^2) -454 +45^2
y = -(x -45)^2 +1571
Because the leading coefficient is negative, we know this vertex represents a maximum. (x, y) = (45, 1571) at the vertex. Maximum profit is $1571.
It would be B. because the rise over run is 31.25 over 5 which is divided to 6.25 which is rounded to 6.3
Answer: (3.3, 3.5)
Step-by-step explanation:
The formula to calculate the confidence interval is given by :-

, where
= sample mean.
z* = critical value.
= Population standard deviation.
n= Sample size.
As per given , we have

n= 217
By using z-table , the critical value for 95% confidence level : z* = 1.96
Now, the 95% confidence interval for the mean consumption of meat among males over age 50 will be :




Hence, the 95% confidence interval for the mean consumption of meat among males over age 50 =(3.3, 3.5)
