Answer: mean=87, median=87.5 and range=18
Step-by-step explanation:
Mean:
First add all the numbers
78+95+77+92+87+79+94+86+88+94 = 870
Then you divide the answer by counting the numbers
870÷10
=87
Median:
First arrange the numbers in ascending order (from smallest to largest)
77, 78, 79, 86, 87, 88, 92, 94, 94, 95
pick the two middle numbers which is 87 and 88
then you do 
= 175÷2
= 87.5
range = Largest number - smallest number
= 95-77
= 18
For A well I can't do a graph ,but to do it you would start at 50 going up 25 each week
For B it would be 300 because 25×10=250 plus the 50 from his grandmother he would have 300
Answer:
10,000
Step-by-step explanation:
9564
9=thousands
5=hundreds
6=tens
4=ones
the number behind the thousands (5) must be 5 or higher to be able to round up. Because the number in the hundreds place is 5, the 9 can round up to 10, making it ten thousand (10,000).
Answer: See explanation
Step-by-step explanation:
By the Triangle Inequality Theorem, the length of the side must be greater than 1 ft because the sum of two side lengths must be greater than the length of the third side. The third side must be less than 7 ft but greater than 1 ft.
Triangle inequality: 1 < x < 7
Hope that helped!
