Answer:
<u>The minimum score Jasmine needs to make on the fifth test to ensure her average is at least 80% is 56%</u>
Step-by-step explanation:
This is the information provided to us to answer the question correctly:
- Score 1st test = 87%
- Score 2nd test = 92%
- Score 3rd test = 76%
- Score 4th test = 89%
- Score 5th test = x
Now, let's calculate the average of Jasmine's scores and to solve for x:
(87 + 92 + 76 + 89 + x)/5 ≥ 80
(344 + x)/5 ≥ 80
344 + x ≥ 80 * 5
344 + x ≥ 400
x ≥ 400 - 344
<u>x ≥ 56</u>

The probability that the 10th will be able to sit on his/her original seat when the 1st person has randomly changed his/her seat is 7/9
Probability :
In Mathematics, Probability stands for the ratio of the number of favorable outcomes to the total number of outcomes in a random experiment. It is used to predict how likely an event can happen.
Probability of an event,
P(E) = No of favorable outcomes / total number of outcomes
Here we have,
10 people always get on a bus in the same order and sit in the same places.
The 1st person has randomly changed his/her seat
Except for 1 remaining number of seats is 9
If 1st person changes his/her place with the remaining 9 seats the number of ways that 1st person can be seated is 9
In 9 ways 10th will be able to sit on his/her original seat when the 1st person is seated in 2 to 9 seats i.e 7 seats
Therefore,
The number of favorable outcomes that the 10th person will be able to seat in his/her original seat = 7
From the above observations,
The probability that the 10th will be able to sit on his/her original seat
= 7 / 9
