Answer:
15/164
Step-by-step explanation:
5/8 ÷ 6 5/6 = 15 / 164
Step-by-step explanation:
step one:
given that the sample space is
red, yellow, green, white, and black. i.e (1+1+1+1+1)= 5
the sample size is 5
the probability of picking a colored card at random is
Pr(a colored card)= 1/5
step two:
without replacement, after the first event, the sample size is now 4
then the probability of picking a colored card at random is
Pr(a colored card)= 1/4
Answer:
It's A
Step-by-step explanation:
Got it right on the practice :)
A. The y-intercept of the function is equal to the value of
y when x = 0, so y = 8 ft
This means that the horse is already 8 ft away from the barn
initially.
B. The average rate of change represents the slope of the
equation. This can be calculated using the formula:
m = (158 – 58) / (3 – 1) = 50 ft / hour
C. Since we already have our y-intercept and slope, we can
establish the line equation:
y = 50 x + 8
When y = 508 then x is,
508 = 50 x + 8
50 x = 500
x = 10 hours
It takes 10 hours to reach a displacement of 508 ft.
