Answer:
Solution to the given expression is 
Step-by-step explanation:
Here, the given expression are:
To Solve for : Q(x) - P(x)
Now substitute the value of P(x) and Q(x) , we get:
Hence solution to the given expression is
Answer:
The box plot below represents the ages of campers at a summer camp. What can be interpreted from this box plot? A. It can be interpreted that about 50 percent of the campers are 8 years of age or younger.
(9 * 2) + 1 = 18 + 1 = 19/2 is it's fractional notation/mixed number.

Answer: 16 miles</h3>
==========================================================
Explanation:
x = time in hours spent going upstream
5-x = remaining time in hours spent going downstream
Those two quantities add to 5 hours total.
Let's find the expression for how far the fisherman went upstream
distance = rate*time
d = r*t
d = 2x
Do the same for the downstream portion
d = r*t
d = 8(5-x)
d = 40-8x
The values of d refer to the same distance because he came back to the starting point.
Set those right hand sides equal to one another and solve for x.
2x = 40-8x
2x+8x = 40
10x = 40
x = 40/10
x = 4
5-x = 5-4 = 1
He spent 4 hours going upstream, and the remaining 1 hour coming back downstream.
--------------
If he spent 4 hours going upstream at 2 mph, then he traveled d = r*t = 2*4 = 8 miles.
The remaining 1 hour going downstream at 8 mph means he traveled d = r*t = 8*1 = 8 miles, which matches with the previous result. This confirms we have the correct one-way distance of 8 miles.
Therefore, the total round trip distance is 2*8 = 16 miles
Answer:
d. will always be unbiased.
Step-by-step explanation:
When some of variables are omitted the estimator on indulge charge regressor may still be unbiased. If there is a special case where T = 2 then the FE estimator will be unbiased. Fixed effect regression model has different intercepts.
