Jacob and issac decided to run to the basketball court after school the basketball court is 5 1/4 Miles from school the boys run

GenaCL600 [577]

Answer: $1\dfrac{5}{9}\text{ minutes}$

Step-by-step explanation:

Complete question is provided in the attachment below.

Given: Jacob and Issac decided to run to the basketball court

Distance between basketball court and school = $5\dfrac{1}{4}$ miles

$=\dfrac{21}{4}$ miles

Speed = $3\dfrac{3}{8}$ miles per hour

$=\dfrac{27}{8}$ miles per hour

Since, time = (distance) ÷ ( speed)

Now, the time taken by boys to arrive at the basketball court = $\dfrac{21}{4}\div\dfrac{27}{8}$ hours

$=\dfrac{21}{4}\times\dfrac{8}{27}\\\\=\dfrac{7\times2}{9}=\dfrac{14}{9}\\\\=1\dfrac{5}{9}\text{ minutes}$

Hence, the required length of time = $1\dfrac{5}{9}\text{ minutes}$

A test score of 48.4 on a test having a mean of 66 and a standard deviation of 11. Find the z-score corresponding to the given

Mariulka [41]

Answer:

A. -1.6; not significant

Step-by-step explanation:

The z-score of a data set that is normally distributed with a mean of $\bar x$ and a standard deviation of $\sigma$ , is given by:

$z=\frac{x-\bar x}{\sigma}$ .

From the question, the test score is: $x=48.4$ , the mean is $\bar x=66$ , and the standard deviation is $\sigma =11$ .

We just have to plug these values into the above formula to obtain:

$z=\frac{48.4-66}{11}$ .

This simplifies to: $z=\frac{-17.6}{11}$ .

$z=-1.6$ .

We can see that the z-score falls within two standard deviations of the mean.

Since $-2\le-1.6\le2$ the value is not significant.

The correct answer is A. -1.6; not significant
