We know that speed * time = distance
Before we start we need to make sure the units for all three numbers are right
The time is 1/3 of a hour, 1/3*60 = 20 minutes
x * 20 = 22.5
x *2 * 10 = 22.5
2x = 2.25
x = 1.125
Answer:
Let's start with part B. if it was originally 10 cm tall and it goes up 0.5 cm. each day, then we know that to go up one cm it needs two days. With that information we can say that 8*2 = 16. So it needs 17 days to go up 8.5 cm which would make it 18.5 cm tall.
Step-by-step explanation:
f(x) = 0.5x + 10
0.5x + 10 = 18.5
0.5x = 18.5 - 10
0.5x = 8.5
x = 8.5/0.5
x = 17 days
(12,200 + 16,211 + 12,050 + 11,350 + 13,325) / 5 = 65136/5 =
13027.2 <== this is the mean (average)
11,350 , 12,050 , 12,200 , 13,325, 16,211
median (middle number) = 12,200
there is no mode...a mode is a number that appears most often...all the numbers appear once in this data.
Answer:
48
Step-by-step explanation:
Use the coordinates of the two black dots:
(2,3) and (7,6)
Slope is the change in Y over the change in X:
Slope = (6-3) / (7-2)
Slope = 3/5
