Answer:
Total time = 56.81/60 + 59.22/60 + 57.39/60 + 60.11/60 = 3.89 minutes
Average Time in Minutes = 3.89 min / 4 = 0.97 minutes
Average Time in Seconds = 0.97 *60 = 58.38 Seconds
Step-by-step explanation:
Answer:
y=3x
Step-by-step explanation:
Use a calculator to guess and check
The relationship between Sabir and calories he burns can be modeled using a linear function given by:
y=ax+b
where
a=slope
b=y-intercept
from the graph, the slope will be given as follows:
taking points (3,15) and (12,60)
a=(60-15)/(12-3)=5 calories/minute
thus using the slope and a point (3,15) the equation will be:
a(x1-x)=(y1-y)
plugging the values we obtain:
5(x-3)=y-15
5x-15=y-15
thus
y=5x
thus the equation is:
y=5x
B-x=3
Solve for x-
4x+1-1=13-1
4x=12
4x/4=12/4
x=3
