An athlete can run 9 kilometers in 1 hour. If the athlete runs at that same average speed for 30 minutes, how far will the athle

butalik [34]

Answer:

Step-by-step explanation:

1 hour = 60 minutes

1 kilometers = 1000m

9 kilometers = 9*1000 = 9000 m

Distance traveled in 60 minutes = 9000 m

Distance traveled in 1 minute = 9000/60

Distance traveled in 30 minutes

$=\frac{9000}{60}*30\\\\=\frac{9000}{2}\\\\$

= 4500m = 4.5 km

Scores on a certain intelligence test for children between ages 13 and 15 years are approximately normally distributed with μ=10

Tanya [424]

Answer:

a) 0.7734

Step-by-step explanation:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this question, we have that:

$\mu = 101, \sigma = 24$
