11 multiplied by 4 = 44....11 multiplied by 3 = 33....44 + 33 = 77....
The second table shows the frequency of the test times. There are 4 numbers that fall between 50-59, 7 between 60-69, 6, between 70-79 and 3 between 80-89
Answer:
Step-by-step explanation:
First move the numbers from the Left hand side to the right hand side. To do so, as it is an equation i.e. both sides must remain the same, you add or subtract the same numbers on both side.
5 + 13k - 61 = 17
5 - 5 + 13k - 61 + 61 = 17 - 5 + 61
13k = 73
k = 73 / 13
k = 5.62 (approximately)
