Answer:
a. The expected or average costs for all weekly rat purchases is $20.00
Step-by-step explanation:
a. A mean value of $20.00 means that over a period of 52 weeks, the company can expect to spend $20.00 per week on rat purchases.
b. This is incorrect since individual values don't interfere in the mean. For instance, if half the weeks had a cost of $19.00 and the other half had a cost of $21.00, the mean cost would still be $20.00 even though no particular week had a $20.00 cost
c. Incorrect. The median is the central value in a distribution; the median and the mean are not necessarily the same.
d. Incorrect, same as item b.

Answer:
See below
Step-by-step explanation:
y = x^2 (x + 4) - 25(x + 4)
y = (x + 4)(x^2 - 25)
y = (x + 4)(x + 5)(x - 5)
- x - 5 is a yes
- x + 2 is a no
- x - 4 is a no
No, the given point does not satisfy the inequality
<em><u>Solution:</u></em>
Given inequality is 6x + y > -11
We have to find whether the point (-2, 1) satisfies the inequality
When we subsitute the given point into given inequality, values in both sides of inequality must satisfy the condition
Let us substitute the given point (x, y) = (-2, 1) in given inequality
6(-2) + 1 > -11
-12 + 1 > -11
-11 > -11 which is not true, Since -11 is equal to -11
So the given point does not satisfy the inequality
