Pete makes 15 dollars an hour. He spends 25 dollars a day ontransportaon and food. Writean expression to describe hisspending and earnings in a day,where h is the number of hoursthat Pete works that day

Answers

Answer: 15h - 25



Explanation: If “h” represents the hours that Pete works that day and we see that Pete makes 15 dollars an HOUR, (which is what h is) then you’ll have 15h. After that we see that it says “He SPENDS (subtraction) 25 dollars a day. So you’d write -25. Put that together and you get 15h - 25. Which is your final answer.

in the figure below, what is the measure of angle x

Answers

Check the picture below.

Location is known to affect the number, of a particular item, sold by an auto parts facility. Two different locations, A and B, are selected on an experimental basis. Location A was observed for 13 days and location B was observed for 18 days. The number of the particular items sold per day was recorded for each location. On average, location A sold 39 of these items with a sample standard deviation of 8 and location B sold 55 of these items with a sample standard deviation of 2. Select a 90% confidence interval for the difference in the true means of items sold at location A and B

Answers

We have two samples, A and B, so we need to construct a 2 Samp T Int using this formula:

[tex]\displaystyle \overline {x}_1 - \overline {x}_2 \ \pm \ t^{*} \sqrt{\frac{s_1^2}{n_1} + \frac{s_2^2}{n_2} }[/tex]  

In order to use t*, we need to check conditions for using a t-distribution first.

Random for both samples -- NOT STATED in the problem ∴ proceed with caution!Independence for both samples: 130 < all items sold at Location A; 180 < all items sold at Location B -- we can reasonably assume this is trueNormality: CLT is not met; n < 30 for both locations A and B ∴ proceed with caution!

Since 2/3 conditions aren't met, we can still proceed with the problem but keep in mind that the results will not be as accurate until more data is collected or more information is given in the problem.

Solve for t*:

We need the tail area first.

[tex]\displaystyle \frac{1-.9}{2}= .05[/tex]

Next we need the degree of freedom.

The degree of freedom can be found by subtracting the degree of freedom for A and B.

The general formula is df = n - 1.

df for A: 13 - 1 = 12df for B: 18 - 1 = 17 df for A - B: |12 - 17| = 5

Use a calculator or a t-table to find the corresponding t-score for df = 5 and tail area = .05.

t* = -2.015

Now we can use the formula at the very top to construct a confidence interval for two sample means.

[tex]\overline {x}_A=39[/tex] [tex]s_A=8[/tex] [tex]n_A=13[/tex] [tex]\overline {x}_B = 55[/tex] [tex]s_B=2[/tex] [tex]n_B=18[/tex] [tex]t^{*}=-2.015[/tex]

Substitute the variables into the formula: [tex]\displaystyle \overline {x}_1 - \overline {x}_2 \ \pm \ t^{*} \sqrt{\frac{s_1^2}{n_1} + \frac{s_2^2}{n_2} }[/tex].

[tex]39-55 \ \pm \ -2.015 \big{(}\sqrt{\frac{(8)^2}{13} +\frac{(2)^2}{18} } } \ \big{)}[/tex]

Simplify this expression.

[tex]-16 \ \pm \ -2.015 (\sqrt{5.1453} \ )[/tex] [tex]-16 \ \pm \ 3.73139[/tex]

Adding and subtracting 3.73139 to and from -16 gives us a confidence interval of:

[tex](-20.5707,-11.4293)[/tex]

If we want to interpret the confidence interval of (-20.5707, -11.4293), we can say...

We are 90% confident that the interval from -20.5707 to -11.4293 holds the true mean of items sold at locations A and B.

How much fabric does Samir need in order to cover 5 of these blocks?


12 cm²

34 cm²

60 cm²

170 cm²

Answers

Answer:

170 cm

Step-by-step explanation:

2 * 1 1/2 * 2 = 6

1 1/2 * 4 * 2 = 12

2 * 4 * 2 = 16

In total: 6 + 12 + 16 = 34.  

Samir needs to cover 5 of these blocks so: 34 x 5 = 170

Solve for v simplify your answer as much as possible: -2 + 3v = -23​

Answers

Answer:

-7

Step-by-step explanation:

-2 + 3v = -23 >> -2 + 23 = -3v >> 21 = -3v >> v = -7

Answer:

V=-7

Step-by-step explanation:

To solve this equation, you must first add the -2 to both sides. (This cancels it out since you only want one variable on each side of the equation. It would be the other way around if the variable were positive) Now that you have the equation 3v=-21, you can divide. To get the v by itself, you must divide both sides by 3. This gives you the answer to the equation.

An airplane flying at 650 miles per hour has a bearing of 54. After flying for 1.5 hours, how far north and how far east will the plane have traveled from its point of departure?

Answers

Answer:

627 miles north

747 miles east

Step-by-step explanation:

Bearing angles are measured east of north, so in (N, E) coordinates, the final position of the plane is ...

 (1.5 h)(650 mi/h)(cos(50°), sin(50°)) = (975cos(50°), 975sin(50°)) mi

 = (626.72, 746.89) mi

The plane will be 627 miles north and 747 miles east of its point of departure.

What is the image point of (-4,8) after a translation right 4 units and up 2 units?

Answers

Answer:0,10

Step-by-step explanation: When translating you either add or subtract. If the problem says go down or to the left, you know that you will be subtracting, and if it says go up or to the right you will be adding. So up would add 4 to the x value which gives you 0 and you add 2 to the y value you get 10.

Answer:

(0, 10)

Step-by-step explanation:

-4 + 4 = 0

8 + 2

To verify, you can find the coordinates (0, 10) on a graph.

whats the soultion for the systeam of eqations

Answers

Answer:

x = 2

y = -3

Step-by-step explanation:

y = x - 5  -------------------(I)

x + y = -1 ----------------(II)

Substitute y = x -5 in equation (II)

x + (x - 5) = -1

x + x - 5 = -1   {Combine like terms}

   2x - 5 = -1 {Add 5 to both sides}

        2x  = -1 + 5

         2x = 4 {Divide both sides by 2}

           x = 4/2

x = 2

Substitute x = 2 in equation (I)

y = 2 - 5

y = -3
