The length of a living room is 12 feet and its width is 10.5 feet. The length of the room is being expanded by x feet.
A. Write an expression to represent the new area of the living room in square feet.
B. Expand the expression.
Answer:
A) A= 10.5(12 +x)
B) A= 10.5x +126
Step-by-step explanation:
A) Length of living room= 12 ft
Width= 10.5 ft
Since the length expanded by x ft,
New length of living room= (12 +x) ft
Area= length ×width
Let the new area of the living room be A ft².
A= 10.5(12+x)
B) To expand the expression, multiply 10 to each term and constant in the bracket on the right hand side of the equation.
A= 10.5(12 +x)
A= 10.5(12) +10.5x
A= 126 +10.5x

A clinical psychologist is the primary therapist for 12 patients. She randomly selects a sample of 3 patients to be in her study. How many different samples of this size can be selected from this population of 12 patients using theoretical sampling and experimental sampling?
(a) theoretical sampling
samples
(b) experimental sampling
samples
Answer:
a)[tex]X=1728[/tex]
b)[tex]X'=220[/tex]
Step-by-step explanation:
From the question we are told that
Population size N=12
Sample size n=3
a)Generally using theoretical sampling we can solve mathematically
[tex]X=N^n[/tex]
[tex]X=12^3[/tex]
[tex]X=1728[/tex]
b)Generally using experimental sampling we can solve mathematically
[tex]X'=^NC_n[/tex]
[tex]X'=^1^2C_3[/tex]
[tex]X'=220[/tex]

Given the function g(x) = x2 + 10x + 19, determine the average rate of change of
the function over the interval -9 < x < 1.
Answer:
The average rate of change of the function over the interval is of 2.
Step-by-step explanation:
Suppose we have a function f(x), over an interval (a,b).
It's average rate of change over the interval is given by:
[tex]A = \frac{f(b) - f(a)}{b - a}[/tex]
In this question:
[tex]g(x) = x^2 + 10x + 19[/tex]
Over the interval -9 < x < 1, so [tex]a = -9, b = 1[/tex]. So
[tex]A = \frac{g(1) - g(-9)}{1 - (-9)} = \frac{g(1) - g(-9)}{10}[/tex]
We have that:
[tex]g(1) = 1^2 + 10(1) + 19 = 1 + 10 + 19 = 30[/tex]
[tex]g(-9) = (-9)^2 + 10(-9) + 19 = 81 - 90 + 19 = 10[/tex]
So
[tex]A = \frac{30 - 10}{10} = \frac{20}{10} = 2[/tex]
The average rate of change of the function over the interval is of 2.

Step-by-step explanation:
(3, 23, 30-39 (extra for 33), 43, 53, 63, 73, 83, 93) x 5 = 95
95 + 100 (from 300's) = 195
Answer:
pretty sure it's 195 times
Step-by-step explanation:
(3, 23, 30-39 (extra for 33), 43, 53, 63, 73, 83, 93) x 5 = 95
95 + 100 (from 300's) = 195

Translate and solve: 662% of what number is 3641?
Answer:
550Step-by-step explanation:
To find the percent of a number, we multiply the number by the decimal form of the percent. The decimal form of a percent can be found by moving the decimal point two places to the left.
Example: 45% = 0.45
In this case, we need to work backward. So, instead of multiplying, we will divide to undo the multiplication.
662% = 6.62
We need to divide 3641 by 6.62 to get the number that 3641 is 662% of. This number will be a smaller number since 662% of a number will be larger than the original number, This is because it is greater than 100%, which would be the number.
Example 100% of 6 is 6 since 6 x 1.00 is 6.
3641/6.62 = 550
However, we can also verify this by multiplying 550 by 6.62 to find 662% of 550.
6.62 x 550 = 3641
