Answer:
94
Step-by-step explanation:
Average = sum of numbers / number of items in the set
for the first list, the average is 90 and there are four numbers, the sum of the numbers is 90 x 4 = 360
If the 4th number is 80, the sum of the first 3 numbers = 360 - 80 = 280
so the sum of the first three numbers on the second list is 260. The fourth number is 96. The sum of the numbers = 280 + 96 = 376
Average of the new list = 376 / 4 = 94
Y=4x-5
If 4 students travelled in cars, then 341 - 5 = 336students travelled by bus.
There were 5 buses. 336÷ 6 = 56
There were 56 students on each bus.
The functions share a y intercept of -1
Both functions cross the y axis and y=-1 and x=0
They both have the same y intercept
