Answer:
y = 6/11 x + 13/11
Step-by-step explanation:
To solve this problem, we have to make use of the standard
probability distribution tables for z test.
Since we are asked to find for the 72 percent level
confidence, then this means we are to look for the value of z which gives
(100-72)/2 = 14% on both sides of the tail.
So at 14% tail on one side, the z value is approximately:
1.08

Answer: 12x² - 5x - 2
Concept:
When doing questions that need to expand algebraic expressions, using the FOIL method will ease the process:
- <u>First </u>means that we multiply the terms which occur in the first position of each binomial.
- <u>Outer</u> means that we multiply the terms which are located in both ends (outermost) of the two binomials when written side-by-side.
- <u>Inner </u>means that we multiply the middle two terms of the binomials when written side-by-side.
- <u>Last </u>means that we multiply the terms which occur in the last position of each binomial.
Solve:
<u>Given expression</u>
(3x - 2) (4x + 1)
<u>Expand parentheses and apply the FOIL method</u>
First: 3x · 4x = 12x²
Outer: 3x · 1 = 3x
Inner: (-2) · 4x = -8x
Last: (-2) · 1 = -2
12x² + 3x - 8x - 2
<u>Combine like terms</u>
12x² + (3x - 8x) - 2
Hope this helps!! :)

For this case we propose a rule of three:
page ----------> hour
x ---------------------------------> 1 hour
Where the variable x is the number of pages written in one hour.
Thus, Ophelia types 2 pages in 1 hour.
Answer:
Ophelia types 2 pages in 1 hour.
Answer: The quotient is (x-2).
Step-by-step explanation:
Since we have given that
Now, we have to find the quotient of the above expression.
So, here we go:
Now, we will divide the above simplest form with g(x):
Hence, the quotient is (x-2).
