Driving Distance Hours Driven Miles Driven 1 60 2 120 3 180 4 ? If Shondra traveled the same number of miles each hour, how many

miles did she travel in 4 hours?
Mathematics
1 answer:
Mashcka [7]3 years ago
8 0

Answer:

the number of miles travelled in four hours in the case when she travelled same miles number each hour is 240 miles

Step-by-step explanation:

The computation of the number of miles travelled in four hours in the case when she travelled same miles number each hour is shown below:

= Number of miles × given number of hours

= 60 miles × 4 hours

= 240 mile

Hence, the number of miles travelled in four hours in the case when she travelled same miles number each hour is 240 miles

In how many ways can 4 singers be selected from 8 who came to an audition?
elena-s [515]

The first selection can be any one of the 8. 
               For each one ...
The second selection can be any one of the remaining 7. 
               For each one ...
The third selection can be any one of the remaining 6. 
               For each one ...
The fourth selection can be any one of the remaining 5.

Total number of ways to select four = (8 x 7 x 6 x 5) = 1,680 ways

BUT ... There are not 1,680 different groups of 4 .

Each group of 4 can be selected in (4 x 3 x 2) = 24 different ways.

So, although there are 1,680 different ways to select 4 singers,
there are only
                           (1,680 / 24) = 70 different groups of 4
                                                     that you can end up with.

What is the location of the point (5, 0) translates 4 units to the down and reflected across the y-axis?
CaHeK987 [17]

STEP-BY-STEP EXPLANATION:

Given information

The given ordered point = (5, 0)

Step 1: We need to translate the point 4 units down

To translate down means we will be subtracting a value from the y--axis

Hence, we have

\begin{gathered} (x,\text{ y) }\rightarrow\text{ (x, y-b)} \\ \text{where b = 4} \\ (5,\text{ 0) }\rightarrow\text{ (5, 0 - 4)} \\ (5,\text{ 0) }\rightarrow\text{ (5, -4)} \end{gathered}

When translated 4 units down, we got (5, -4)

Step 2: Reflect over the y-axis

The general rule for reflecting over the y-axis is (-x, y)

This means the value of x will be negated and the value of y will remain the same

\begin{gathered} \text{Over the y-ax}is \\ (x,\text{ y) }\rightarrow\text{ (-x, y)} \\ (5,\text{ -4) }\rightarrow\text{ (-5, -4)} \end{gathered}

Step 3: the graph the point

A hypothesis test is conducted at the .05 level of significance to test whether or not the population correlation is zero. If th
finlep [7]

Answer:

Th computed value of the test statistic is 3.597

Step-by-step explanation:

The null and the alternative hypothesis is as follows:

Null Hypothesis:

\mathbf{H_o:} the population correlation coefficient is equal to zero

\mathbf{H_a:} the population correlation coefficient is not equal to zero

The test statistics for Pearson correlation coefficient is thus computed as :

t =\dfrac{r \sqrt{(n-2)}} { \sqrt{(1-(r)^2)} }

where;

r = correlation coefficient = 0.60

n = sample size = 25

So;

t =\dfrac{0.60 \sqrt{(25-2)}} { \sqrt{(1-(0.60)^2)} }

t =\dfrac{0.60 \sqrt{(23)}} { \sqrt{(1-0.36} }

t =\dfrac{0.60 *4.796} {0.8}

t = 3.597

Comparing to a critical value of t (23 degrees of freedom two-tailed value) = 2.069

Decision Rule:

Since computed value of t is greater than the critical value of t; We reject the null hypothesis and accept the alternative hypothesis.

Conclusion:

We conclude that the population correlation coefficient significantly differs from 0 at 5% (0.05) level of significance.
