you must have an average score of at least 80 to get a B on your report card. You have scores of 61,70,99, and 70. What is the minimium score you must get on the last test to get a B on your report card?
the minimum score you can make and receive an 80 is 100
The minimum score does not require an inequality.
Mean (average) = Sum of scores/N (number of scores)
80 = (61 + 70 + 99 + 70 + X)/5
Solve for X.
I hope this helps a little more. Thanks for asking.
Your average score is currently (61+70+99+70)/4 = <<(61+70+99+70)/4=75>>75
To get a B, you need an average of at least 80, so you need a score of 80-75 = <<80-75=5>>5 higher on your last test.
Thus, you need a minimum score of 70+5 = <<70+5=75>>75 on the last test to get a B. Answer: \boxed{75}.
Well, if you want some humor, I have a funny answer for you. To get a B on your report card, you have to summon the ancient and magical "Studyhardicus" creature. Legend has it that it will grant you a minimum score of 80 on your last test. Just be careful, because this creature only appears to those who have truly mastered the art of procrastination. Good luck!
To find the minimum score needed on the last test to get a B on your report card, you can follow these steps:
1. Calculate the sum of the four given scores: 61 + 70 + 99 + 70 = 300
2. Add the variable representing the score on the last test: 300 + X
3. Divide the sum by the total number of scores, which is 5 because you have four given scores plus the last test score: (300 + X) / 5
4. Set up an equation to find the minimum required score by equating the average (mean) to 80: (300 + X) / 5 = 80
5. Multiply both sides of the equation by 5 to remove the denominator: 300 + X = 400
6. Subtract 300 from both sides of the equation: X = 100
Therefore, the minimum score you must get on the last test to get a B on your report card is 100.
To find the minimum score you must get on the last test to get a B on your report card, you can set up an equation using the average formula.
The formula for the average (mean) is:
Average = Sum of all scores / Number of scores
In this case, the average score must be at least 80 to get a B. You have scores of 61, 70, 99, and 70, and you need to find the minimum score you must get on the last test (let's call it X).
So, we can set up the following equation:
80 = (61 + 70 + 99 + 70 + X) / 5
To find the minimum score required, we need to solve for X.
Multiply both sides of the equation by 5:
400 = 61 + 70 + 99 + 70 + X
Combine the numbers on the right side of the equation:
400 = 300 + X
Subtract 300 from both sides of the equation:
400 - 300 = X
100 = X
Therefore, you need to score at least 100 on the last test to get a B on your report card.
