solve normally & thats how you get your answer
Answer:
10
Step-by-step explanation:
Anything greater than 9.49 would be rounded to 10, if it were 9.49, it would be rounded to 9. But only look at the numbers after the decimal.
i.e. ;
7.23 = 7
3.33 = 3
8.89 = 9
14.56 = 15
26.91 = 27

Answer:
2.275%
Step-by-step explanation:
We solve this question using z score formula
z = (x-μ)/σ,
where
x is the raw score = 70 mph
μ is the population mean = 100 mph
σ is the population standard deviation = 15 mph
z score = 70 - 100/15
z score = -30/15
z score = - 2
Determining the Probability value from Z-Table:
P(x ≤ 70) = P(x < 70)
= P(z = -2)
= 0.02275
Hence the probability of the player's serve that are less than 70 mph is 0.02275
Converting it to percentage
= 0.02275 × 100
= 2.275%
Therefore, the percentage of the player's serve speeds that are less than 70 mph is = 2.275%
