Find the mean of the first four test scores first.
(Add all numbers in set and divide by how many numbers there are)
81 + 87 + 71 + 89 = 328 / 4 = 82
Then, find the mean with the 85 added as the fifth term.
81 + 87 + 71 + 89 + 85 = 413 / 5 = 82.6
The impact that the 85 had on the mean test score was that the mean/average increased by 0.6.
A.) the greatest amount of boxes would probably be 8
B.) the amount of cars would be 5 and the airplanes would be 3
21/49
=3/7(divide by 7 numerator and denominator)
PLs brainliest answer
Answer:
Option B
Step-by-step explanation:
we know that
A <u>rational number</u> is one that can be represented as the ratio of two whole numbers
so
-----> Is not a rational number, because √5 is not a whole number, is a irrational number
---> Is a rational number, because can be represented as the ratio of two whole numbers
therefore
√5/8 is irrational and √4/9 is rational
