3 would be 36 4 is 47 6 is 69 and 8 is 91
Answer:

The graph is also attached below.
Step-by-step explanation:
Given the expression

We know that the domain of a function is the set of inputs or argument values for which the function is real and defined.
We know that we can not have a negative value of 't' inside the radicals because if we put any negative number inside the radical expression, it would make the function undefined.
In other words, the value of t ≥ 0.
Therefore, the function domain is:

Answer:
-12r2-9r-6
Step-by-step explanation:
-distribute the subtraction symbol to the second group of numbers
-(9r2+7r+2) = (-9r2-7r-2)
-then combine each term together (-3r2-2r-4)+(-9r2-7r-2)
= -12r2-9r-6

Answer:
D is halved
Step-by-step explanation:
Given :
If n is doubled :
- D' = -dv/60(2n)
- D' = -dv/120n
- D' = D/2
When n is doubled, D (<u>the drop factor</u>) is half of its original value.
Answer:
Step-by-step explanation:
Step-by-step explanation:
The given data set is:
Week 1: 600
Week 2: 300
Week 3: 500
Week 4: 900
The following are the steps to find the standard deviation:
Step 1. Jim enters the data and calculates the average or mean.
Step 2. Jim calculates the deviation from the mean by subtracting the mean from each value.
Data value (x)
600 25
300 -275
500 -75
900 325
Step 3. Jim squares each deviation to remove negative signs.
Data value (x)
600 625
300 75625
500 5625
900 105625
Step 4. Jim sums the squares of each deviation and divides by the count for the variance.
Step 5.Jim takes the square root of the variance to find the standard deviation.
