Answer:
Step-by-step explanation:
R=x/7 let's say R is what Ryan earned, and so he earns x dollars every seven days
L=2(R)
L=2(x/7)Let's say L is what Lee earned, she earned twice as much as Ryan so 2(x/7)
Total=2(x/7)+x/7
Total=3(x/7) the total earnings is the sum of x/7 and 2x/7 is 3x/7
Answer:
Step-by-step explanation:
Given


Required
Function from K to F
This implies that, we calculate F(k)
Given that:

Substitute c(k) for c

Substitute: 

Hence:

I mean they both have a factor of 3 you just take -3x > 9 and just flip it
Answer:

Therefore the probability that a randomly selected student has time for mile run is less than 6 minute is 0.0618
Step-by-step explanation:
Normal with mean 6.88 minutes and
a standard deviation of 0.57 minutes.
Choose a student at random from this group and call his time for the mile Y. Find P(Y<6)


y ≈ normal (μ, σ)
The z score is the value decreased by the mean divided by the standard deviation

Therefore the probability that a randomly selected student has time for mile run is less than 6 minute is 0.0618
