Answer:
5x+2
Step-by-step explanation:
P=2L+2W
14x+4=2(2x)+2W
14x+4=4x+2W
14x+4-4x=2W
14x-4x+4=2W
10x+4=2W
(10x+4)/2=W
5x+2=W
To solve this question, we simply need to subtract the two numbers.
We'll start by changing these into improper fractions to simplify things for now.
Now, we need to make these fractions share a common denominator. We'll do this by multiplying the second fraction by . Keep in mind that whatever is done to the denominator must also be done to the numerator.
Finally, subtract the numerators and keep the denominators.
We can simplify this fraction by dividing both the numerator and the denominator by .
Answer:
The point estimate of the standard deviation for the population of NFL games is
Step-by-step explanation:
a) Develop a point estimate of mean fan rating for the population of NFL games
The point estimate is the mean of the sample.
The mean is the sum of the values divided by the number of values. There are 12 values, so:
The point estimate of mean fan rating for the population of NFL games is 60.08.
b. Develop a point estimate of the standard deviation for the population of NFL games (to 4 decimals).
This point estimate is the standard deviation of the sample.
The standrd deviation of a N-cardinality set is given by the following formula:
where is the element at the position k of the set and M is the mean of the set.
For this sample, we have that the standard deviation(using a calculator) is:
The point estimate of the standard deviation for the population of NFL games is
Answer:
f(x) = 3x²
Step-by-step explanation:
<u>Quadratic Function :- </u>
The function whose highest degree of variable is 2 is called a quadratic function .
- On looking at the given options , we see that the third options satisfies the definition of Quadratic Function . That is,
f(x) = 3x²
<h3>
<u>Hence</u><u> the</u><u> </u><u>third </u><u>option </u><u>is</u><u> </u><u>correct</u><u> </u><u>.</u></h3>
