A unit rate is a ratio with a number in comparison to 1 (per 1). So, In this case...
C) Sara is driving 30 miles per 1 hour is an example of unit rate.
Answer:
Step-by-step explanation:
- <em>Binomial = 2 terms in the expression</em>
- <em>Third degree = highest added degree of variables in one term</em>
(A) It has 3 terms and highest degree of 4. It is trinomial of degree 4.
(B) It has 2 terms and highest degree of 3. It is binomial of degree 3.
(C) It has 2 terms and highest degree of 7. It is binomial of degree 7.
(D) It has 2 terms and highest degree of 3. It is binomial of degree 3.
18 times
Since there only two numbers greater than 4 (5 & 6), you subtract 2 from 6.

Then, you divide that from 72.

So, the number of times I would expect the outcome to be greater than 4 is 18.

So, to find the mean they added up the scores from 20 seasons and divided by 20, the number of seasons to get an average score of 10.4.
10.4 = (x1 +x2 +x3 ... +x20 )/20
Then;
10.4*(20) = (x1 +x2 +x3 ... +x20 )
208 = sum of the first 20 seasons
We want to add one more number in there, the 21st season with a score of 14. Add the 14 to the sum of the first 20 seasons and then divide by 21, the new number of seasons you're averaging.
Mean = (208+14)/21
