A rectangular room measures 21 feet by 28 feet with a 10-foot-high ceiling. The flooring is being replaced with carpeting that sells for $10.45 per square foot and entails a $149 installation fee. What is the total pricing for the carpeting with an 8.0% sales tax

Answers

9514 1404 393

Answer:

  $6,797.09

Step-by-step explanation:

The area of the floor is ...

  (21 ft)(28 ft) = 588 ft²

Then the cost of the carpet material is ...

  (588 ft²)($10.45/ft²) = $6,144.60

The subtotal with installation fee is ...

  $6,144.60 +149.00 = $6,293.60

Adding the sales tax multiplies this amount by 1 +8% = 1.08, so the final price is ...

  1.08 × $6,293.60 = $6,797.09 . . . total price

Verbally describe what each ordered pair in the first row of your table (when s = 10) means in terms of the situation. Use complete sentences in your answer.

Answers

The description of what each ordered pair means is; as described below

How to interpret Ordered Pairs?

The table is missing but from online sources, we can say the following;

An ordered pair such as (2,4), is a short form of writing two variables, such as x = 2 and y = 4. The order of the numbers in the pair is important because x always comes before y.

An ordered pair is simply a composition of the x coordinate called abscissa while the y coordinate is called the ordinate.

Thus, the Ordered Pair is (x,y)

Where,

x is the distance measure of a point from the primary axis "x"

y is the distance measure of a point from the secondary axis "y"

In the Cartesian plane, the point where the two lines meet at “0” is the origin.

An ecological group suspects lobsters are consuming dangerous levels of mercury in a region of the world. Dangerous levels of mercury are classified when they reach beyond 6.5 parts per million. A random sample of 25 lobsters in the region were tested and the data is shown in the stemplot.

Stemplot for Mercury Levels.

5|0 1 3 3 4;
5|6 8 9;
6|3 4;
6|6 7 8;
7|1 2;
7|

Key: 2|2 = 2.2 parts per million

Part A: What proportion of the lobsters in the sample have dangerous levels of mercury in their systems? (4 points)

Part B: Construct and interpret a 95% confidence interval for the mean mercury levels of the lobsters if the sample of 25 lobsters has a mean mercury level of 5.05 parts per million and standard deviation of 1.45 parts per million. (6 points)

Answers

Part A: 5 out 25 lobsters have dangerous levels of mercury

Part B: the 95% confidence interval is given by (4.45, 5.65)

since everything is given all I had to do is find the critical value which can be found from the resource packet = 2.064

Using the formula we find 5.05+-2.064*1.45/5 = ( 4.45,5.65)

For this case, we have 95% of confidence that the true mean for the average number of lobsters with dangerous levels of mercury is between 4.45,5.65

A man walks five miles east, and then walks five miles west. What is the total distance from his starting point?

Answers

Answer:

0 miles

Explanation:

Step 1) -----> 5 miles west

Step 2) <----- 5 miles east

So in conclusion I think that the man came back to where he started.

Compass:

                          N

                    W          E

                            S

Answer:

15 miles.

Step-by-step explanation:

5 + 10 = 15

5 represents the fact that he walked 5 miles east, and then if he were to walk from there towards the west, that would be 10 miles because if its 5 miles from his starting point to the east, then it would be double from the east to the west so if you add 5 miles and 10 miles, you should get a total of 15 miles.

Note. The first question is repeated as A and B

A) KR = 1/2KM

Substitute and solve for x:

x + 7 = 1/2(3x - 5)2x + 14 = 3x - 53x - 2x = 14 + 5x = 19

Find JR

JR = 1/2JL JR = 1/2(4x - 10) = 2x - 5 = 2*19 - 5 = 34 - 5  = 29

B)
