Answer:

hello your question is incomplete below is the complete question

The Honda Accord was named the best midsized car for resale value for by the Kelley Blue Book (Kelley Blue Book website). The file AutoResale contains mileage, age, and selling price for a sample of 33 Honda Accords. Click on the datafile logo to reference the data. The estimated regression equation is Selling price = 20385.25049 - 0.03739 Mileage - 686.33668 age. Round your answers to the nearest dollar. a. Estimate the selling price of a four-year-old Honda Accord with mileage of 40,000 miles.

answer :  ≈ $16144

Step-by-step explanation:

<u>Determine the selling price of a four-year-old Honda Accord with mileage of </u><u>40,000</u><u> miles.</u>

Given data :

Age= 4 year, Mileage=40,000 miles

Hence the selling price

= 20385.25049 - 0.03739 Mileage - 686.33668 age

=  20385.25049 - 0.03739(40,000)  - 686.33668 ( 4 )

= $16144.32

A rope is cut into three pieces of different lengths. The first piece is of length x meters, The length of the second piece is 2
Iteru [2.4K]

Answer:

first piece = 5 m

second piece = 2(5) + 2 = 12 m

third piece = 3(2x + 2) = 6(5) + 6 = 36 m

Step-by-step explanation:

The question is incomplete, the length of the actual rope is unknown but it should be given . Let us assume the length of the rope is 53 meters.

The rope is cut into 3 pieces of different length.

first piece = x

second piece = 2x + 2

third piece = 3(2x + 2) = 6x + 6

Since the length of the actual rope is assumed to be 53 meters .The length of the first piece, second piece and third piece can be calculated as follows.

we add the length of the pieces to get the actual length of each piece. Therefore,

x + 2x + 2 + 6x + 6 = 53

collect like terms

9x + 8 = 53

9x = 53 - 8

9x = 45

x = 45/9

x = 5 meters

first piece = 5 m

second piece = 2(5) + 2 = 12 m

third piece = 3(2x + 2) = 6(5) + 6 = 36 m

Round <br> 653<br> ,<br> 500<br> 653,500653, comma, 500 to the nearest thousand.
Jlenok [28]

Answer:

Do you mean to round the number 653,500,653,500,653,500? Or do you mean to round the number 653,500? If so, for 653,500, the digit in the thousand's place is 5, so it's already rounded to the nearest thousands place.

bulgar [2K]

Complete Question:

To create a bulletin board, Maryann is planning to stretch fabric from burlap sacks over cardstock. She collects 6 kg of burlap sacks. The area density of the burlap is 0.4 kg/m².

Maryann's friends loved her bulletin board , and 4 of them asked her to make one for their homes. She offered to make each of her friends a replica of her bulletin board that measures 2 meters by 3 meters . How many kilograms of burlap should Maryann collect to complete the bulletin boards for her friends?

Answer:

To complete the bulletin boards for her friends, Maryanne should collect 6 kg of burlap more

Step-by-step explanation:

Mass of burlap sacks that Maryann collects = 6 kg

Area density of burlap = 0.4 kg/m²

Area Density = Mass / Area........(1)

The Area of bulletin board that can be made with the 6 kg of burlap sand can be calculated by using equation (1)

0.4 = 6 / Area

Area = 6/0.4

Area of bulletin board that can be made from 6 kg= 15 m² of bulletin board  

The area of bulletin board that Maryann made for herself = 2 * 3 = 6m²

To make similar bulletin boards for her four friends, the total area of bulletin board made for her 4 friends = 6 * 4 = 24m²

To calculate the mass of burlap required to make a 24m² bulletin board, use equation (1)

0.4 = Mass / 24

Mass = 0.4 * 24

Mass = 9.6 kg

The mass of burlap used to make Maryann's bulletin board alone:

0.4 = Mass/6

Mass = 2.4 kg

Out of the 6kg that she got, she has used 2.4 kg for herself

The remaining mass of burlap = 6 - 2.4 = 3.6 kg

Therefore, to complete the bulletin board for her friend, she should collect (9.6 - 3.6) = 6 kg of bulletin more

Suppose lifetime of certain type of car batteries are
masya89 [10]

Answer:

Follows are the solution to the given points:

Step-by-step explanation:

The brand (M) will become more reliable as the standard deviation of an (M) brand will be much lower than the standard deviation of (G) brand.

such as four years,

Calculating the z score for G brand= \frac{(4-3)}{1} = \frac{1}{1} = 1

Calculating the z score for M brand= \frac{(4-3)}{(\frac{1}{3})} = \frac{(1)}{(\frac{1}{3})} = 1 \times \frac{3}{1}= 3.

Because the z mark of the (G) brand is less, it is much more probable that the (G) Brand could last four years. It is because the variability of the (G) brand is very high, which allows lasting longer by expanding its expansion.

Brrunno [24]

Answer:

The answer in the procedure

Step-by-step explanation:

we know that

<u>Vertical Angles</u> are the pair of congruent angles opposite each other when two lines cross

In the given figure

(2x+6)\°=96\° -----> by vertical angles

solve for x

2x=96\°-6\°

2x=90\°

x=45\° ------> is ok
