A) The first one equals to 5
Step by step:
Change all denominators to 28, what you do to the bottom you do to the top.
After adding simplify.
It's dividing by 2.
Next 3 would be: 25, 25/2, 25/4 or converting those into decimals.
It would be a. 8/9 because for every 8/9 boy, there is 1 girl. To check this work, you can do 8/9 x 18 which equals 16.
95,000 / 125,000 = 0.76
which means she was ranked in the upper quartile or the 76th percentile
Answer:
Jay's estimate is closer to the actual weight of the basketball
Step-by-step explanation:
The standard weight of an NBA basketball is 1.4 pounds.
Judging the accuracy of Jay's and Shawna's answer based on their percentage error when compared with the standard, we have that Jay's answer has a lower error as shown below
Error = (Standard value - Estimated value)/ Standard Value ×100
Error in Jays answer =
× 100 = 64.28 %
Error in Shawna's answer =
× 100 = 96.42%
From this, It is obvious that Jay's answer has a lower percentage error when compared to the actual value.
