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: is C
Step-by-step explanation:
Answer:
Option A) any numerical value in an interval or collection of intervals
Step-by-step explanation:
Continuous Random Variable:
- A continuous random variable can take any value within an interval.
- Thus, it can take infinite values since there are infinite numbers in an interval.
- A continuous variable is a variable whose value is obtained by measuring.
- Examples: height of students in class
, weight of students in class, time it takes to get to school, distance traveled between classes.
- Thus, the correct meaning of continuous random variable is explained by Option A)
Option A) any numerical value in an interval or collection of intervals

Answer:
Step-by-step explanation:
123/6 x 7[(654 + 2) x (12/3)].....do whats in parenthesis first
123/6 x 7[656 x 4] ......do whats in brackets
123/6 x 7(2624) ....do multiplication/division from left to right, whichever comes first
