Answer:

  100

Step-by-step explanation:

Suppose there are 2n+1 students in the class. If n+1 of them score 91, and n of them score the high score h, for the average to be 95, we must have ...

  91(n+1) +nh = 95(2n+1)

  91n +91 +nh = 190n +95

  nh = 99n +4

  h = 99 +4/n

The high score must be greater than 99. The high score must be 100.

Can someone help with this
Anit [1.1K]

Answer: Draw a line through the two points (0,2) and (3,3). See the attached image below.

How did I get these two points? The first point comes from the fact that "at the start, the height is 2 inches" meaning that x = 0 hours and y = 2 inches pair up together. This is show as point A. This is the y intercept as this is the location where the blue graph crosses the vertical y axis.

Point B is found by moving 1 unit up from point A and 3 units to the right to land on (3,3). So we have x = 3 hours and y = 3 inches pair up together.

Note: the slope is rise/run = 1/3 helping us determine the unit rate or speed in which the water is rising (ie the water is rising one-third of an inch per hour)

Points (-21, 5) and (-7,y) have a slope of 5. Find the y coordinate of the point.
hjlf

Answer:

80

Step-by-step explanation:

The equation of finding a slope is y2-y1/x2-x1.

y-5/-7-(-21)=5

y-5/-7+21=5

y-5/15=5

y-5=75

y=80
