Answer:
a. 20 points
Step-by-step explanation:
Range = Largest given value - Smallest given value.
<u>Identifying the range of test 1</u>
Looking at the dot plot the lowest test grade appears to be 50 while the highest is 90.
So range of test 1 = 90 - 50 = 40
<u>Identifying the range of test 2</u>
Looking at the plot the lowest test grade appears to be 40 while the highest appears to be 100
So range = 100 - 40 = 60
<u>Identifying the differences between the ranges</u>
Test 1 range : 40
Test 2 range : 60
Difference between the two : 60 - 40 = 20 points
Answer:
2.50$
Step-by-step explanation:
Answer:
9 tapes
Step-by-step explanation:
First, subtract the handling charge from his $78.
78 - 3.50 = 74.5
So, Brian has $74.50 to purchase tapes. Each tape costs $7.50, so let's find out how many he can purchase.
74.50 / 7.50 = 9.933 (approximately)
Since Brian can't buy 0.933 of a tape, he will only be able to buy 9 tapes.
5 + 8 = 13
169/13 = 13
13 * 5 = 65
13 * 8 = 104
Thus, 65:104
