Answer: 81%
Step-by-step explanation:
From the question, we are informed that a student received the following test scores: 71%, 89%, 72%,
84% and 83% in 5 tests and the student wants to maintain an average of 80%.
The lowest score/grade they can receive on the next test to maintain at least an 80% average first thus:
First, to make it easy we can remove the percent sign. Then we multiply 80 by 6 since we're calculating for 6 tests scores. This will be:
= 80 × 6
= 480
We then add all the 5 test scores. This will be:
= 71 + 89 + 72 + 84 + 83
= 399
We then subtract the values gotten. This will be:
= 480 - 399
= 81
This means the student must get at least 81%
Answer:
B
Step-by-step explanation:
5(t - 1) = 5t - 5
B, 5t + (-5)
+ and - make -
5t - 5
A number version for it would be 348.
Hope it helps!
Wow, that is definitely a pickle, but what if you took the 14 percent that dont know, multiply it by 9590 to get how many people dont know, THEN took each percent of THAT new population to estimate how many of the "dont knows" would fall into each section then? do you get what im saying?
