The fastest a human has ever run is 27 miles per hour. How many miles per minute did the human run?

Answers

Answer:

0.45 miles per minute

Step by Step Explanation:

Look at the units:  miles per hour is miles/hour

If we multiply

 

miles       hour         miles

-----   *     -------  =  ---------

hour       minute      minute

 

(27 miles/hour)(1/60 hours/minute) = 27/60

 

= 9/20 = 0.45 miles per minute

Thomas, a waiter at a local restaurant, is paid $ 4 an hour plus tips. His friend Marie works at a local bookstore for $12 an hour. Marie and Thomas worked the same number of hours. If Thomas made $120 in tips and both made the same amount of money, how many hours

Please just write the equation out.

Answers

Let h be the number of hours worked.
Let x be the tips
Let t be Thomas
Let m be Marie’s pay

t=4h+x

(plug in 120 for x)

t=4h+120
——————————————
m=12h

(They made same amount of money working the same amount of hours)

4h+120=12h
120=8h

How many hours did they both work? :)

Topic: Parallel and Perpendicular Lines

B.y = x 8 and y= -x –
C. y = x + 2 and y
-x+3
D.y = 3x + 2 and y = 3x - 2
E.y=3 and x = 4
F. y = x 8 and y = -x + 3

Answers

Answer:

Step-by-step explanation:

If slope of two lines are equal, then they are parallel lines.

If product of the slope of two lines is (-1), then they are perpendicular lines.

C) y = x + 2

Slope m1 = 1

y = -x + 3

Slope m2 = -1

m1 * m2 = 1 * (-1) = -1

These are perpendicular lines.

D) y = 3x + 2

Slope = m1 = 3

y = 3x - 2

Slope = m2 = 3

Slopes are equal. So, they are parallel lines.

E)y= 3

This line is parallel to x -axis.

x = 4

This line is parallel to y-axis.

So, both lines are perpendicular to each other.

F) y = x + 8

slope m1  = 1

y = -x + 3

Slope = m2 = -1

M1 * m2 = 1 * (-1) = -1

So, These are perpendicular lines

Write and inequality to compare the fractions. 24/18 and 25/15

Answers

Answer:

25/15 > 24/18

Step-by-step explanation: Both of these fractions can be reduced so that the denominator is 3. This will make it much easier to compare the two fractions. For 24/18, if you divide both the numerator and the denominator by 6, then the fraction simplifies to 4/3. For 25/15, if you divide the numerator and denominator by 5, then the fraction simplifies to 5/3. Since these fractions have a common denominator, the fraction with the larger numerator is going to be the larger fraction. So, 25/15 is greater than 24/18.

Take LCM in the bracket as 10

⇒ [(2 + 5)/10]² + 15/10

⇒ (7/10)² + 15/10

⇒ 49/100 + 15/10

Take LCM as 100

⇒ (49 + 150)/100 = 199/100

⇒ 1 99/100

Hence "The resultant of the expression (1/5+1/2)^2+3/10⋅5 in mixed number will be 1 99/100".

For every foot it needs to be 12 ft. So 1 3/4 is 1 foot and 9 inches. Cause we have the whole number which is 1 and 3/4. 3/4 isn’t a whole number it’s a fraction of 12. 1/4 if 12 is 3 cause 12 split into 4 parts is 3. Now we have 3/4 which is 3 of the 1/4ths. We said 1/4 is 3 and if we have three then we multiply 3 x 3 and get 9.

So

1 ft 9 in

But it says to round to the nearest integer so 1 turns to 2.

Write the equation of the line in fully simplified slope Intercept form.

Answers

Answer:

y = -0.83x - 2

Step-by-step explanation:

Slope intercept form is y = mx+b.

M is the slope: In this case the slope (rise/run) is 10/12. However, the slope is decreasing is that would make it negative.

Now we have: y = -0.83x + b

B represents the y-intercept. The y-intercept here is -2. So our final equation is:

y = -0.83x - 2

It currently takes users a mean of 25 minutes to install the most popular computer program made by RodeTech, a software design company. After changes have been made to the program, the company executives want to know if the new mean is now different from 25 minutes so that they can change their advertising accordingly. A simple random sample of 51 new customers are asked to time how long it takes for them to install the software. The sample mean is 26.2 minutes with a variance of 16 minutes. Perform a hypothesis test at the 0.01 level of significance to see if the mean installation time has changed. What kind of problem is this

Answers

Testing the hypothesis in this problem which is a two-tailed test, we can conclude that there is not sufficient evidence to conclude that the mean time of installation has changed, since the p-value of the test is 0.0364 > 0.01,

At the null hypothesis, we test if the mean is of 25 minutes, that is:

[tex]H_0: \mu = 25[/tex]

At the alternative hypothesis, we test if the mean has changed, that is, if it is different than 25 minutes.

[tex]H_1: \mu \neq 25[/tex]

We have the standard deviation for the sample, thus, the t-distribution is used. The value of the test statistic is:

[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]

In which:

X is the sample mean.[tex]\mu[/tex] is the value tested at the null hypothesis.s is the standard deviation of the sample.n is the sample size.

In this problem:

25 is tested at the null hypothesis, thus [tex]\mu = 25[/tex].Sample mean of 26.2 minutes, thus [tex]X = 26.2[/tex].Sample of 51, thus [tex]n = 51[/tex].Variance of 16, thus [tex]s = \sqrt{16} = 4[/tex].

The value of the test statistic is:

[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]

[tex]t = \frac{26.2 - 25}{\frac{4}{\sqrt{51}}}[/tex]

[tex]t = 2.14[/tex]

The p-value of the test is found using a two-tailed test(test if the mean is different of a value), with t = 2.14 and 50 degrees of freedom.Using a t-distribution calculator, this p-value is of 0.0364.

Since the p-value of the test is 0.0364 > 0.01, there is not sufficient evidence to conclude that the mean time of installation has changed.
