Answer:
4.464 ml
Step-by-step explanation:
Given that:
mean (μ) = 5 mm, standard deviation (σ) = 0.4 ml
The z score is a score in statistics used to determine by how many standard deviation the raw score is above or below the mean. If the z score is positive then the raw score is above the mean and if the z score is negative then the raw score is below the mean It is given by:

From the normal distribution table, the 9th percentile (0.09) corresponds to a z score of -1.34

The dye amount that represents the 9th percentile of the distribution is 4.464 ml
Answer:
80 minutes
Step-by-step explanation:
The ratio can be simplified and rewritten:
minutes : miles = 24 : 3 = 8 : 1 = 80 : 10
It will take Josie 80 minutes to run 10 miles at her 8 minutes/mile pace.
Answer:
A.96.25 steps. B. Approximately 37 steps shorter
Step-by-step explanation:
From Pythagoras theory,
Hyp² = Adj² + Opp²
Hyp² = 52² + 81²
Hyp² = 2704 + 6561
Hyp² = 9265
Hyp = √9265
Hyp = 96.25 steps
= 81 + 52 = 133 - 96.25
= 36.75 or approximately 37 steps shorter
Answer:
3/4
Step-by-step explanation:
