Answer:
I say the answer is ball 4
Step-by-step explanation:
The reason why I chose ball 4 was because ball 4 has less mass and the mass for ball 4 is only 300 and I'm pretty sure if you rolled ball 4 it would've went the farthest because it's mass is lesser than the others.
Answer:
96 marks
Step-by-step explanation:
We know that the mean of a given amount of values is the sum of the values divided by the number of values
Let the marks in the fourth test = x marks
Mean of the values = 90
(85 + 90 + 89 + x) / 4 = 90
264 + x = 360
x = 96
Therefore, Jamie needs 96 marks in her 4th test to get a mean score of 90
