Answer:
Part A: 81.5%
Part B: About 95% of the data lie between 53 and 65.
Step-by-step explanation:
Note: the percentages marked in red and blue never change
For Part A, we add the percentages that are between 53 and 62. So, 34% + 34% + 13.5% which is 81.5%
For Part B, we can look at this graph and seen that 95% of this data set lies between 53 and 65
Hope this is correct and of help!
Turn equation around:
7u-9-12u=26
Combine like terms:
-12u+7u=-5u
This turns equation into:
-5u-9=26
Add -9 to both sides:
-5u-9=26
+9=+9 - and + cancel out
-5u=35
Divide by -5 to get “u” by itself:
-5u=35
———— -5 And -5 cancel making
-5 =-5 “u” By itself
u= -7
Hope this helps!
