Help!!!!!!!!! An automotive service center would like feedback on its customer service Each customer receives a printed card
after they pay for services with a short survey on which customer service is ranked on a scale from 1 (least
satisfied) to 6 (most satisfied) Customers can then choose to submit the card in a box on their way out of the store.
The store manager finds that 140 cards were filled out in the past week, with an average customer satisfaction
score of 2.47 Which type of bias is most likely to be present in the survey results?
This is undercoverage bias because some types of customers may not have received cards,
This is nonresponse bias because many customers may choose to not fill out the cards
This is question wording bias because the customer service score levels may not be clear to customers.
This is response bias because customers may not be truthful about their experience with customer service.

Answer:

  a) the x-coordinate changes sign

  b) the y-coordinates are unchanged

  c) this is a reflection across the y-axis

Step-by-step explanation:

Each image point is on the same horizontal line as the original. It is as far from the y-axis as the original, but in the opposite direction. Its x-coordinate has changed sign.

__

The y-coordinate is the same for each image point as for the original. The y-coordinates have not changed.

__

The line of reflection is the perpendicular bisector of the segment joining the original point and its image. In every case, that is the y-axis. The image is a reflection across the y-axis.

Answer:

The value of x is 20 degrees.

Step-by-step explanation:

The three angles of a triangle must equal 180 degrees.

100 + 40 + 2x = 140 + 2x

180 - 140 = 40 (goal)

2(x) = 40

2(20) = 40

A) 20 degrees

Answer:

(x³+2x²-2x)-(-3x³+4x²-x)

(x³+2x²-2x)+(3x³-4x²+x)

(x³+3x³)+(2x²-4x²)+(-2x+x)

4x³-2x²-x ----you may write till here.

Answer:

B. H(w) gets very small.

Step-by-step explanation:

This should be the answer you're looking for

From the graph of H(w) and w, H(w) gets very small when w gets very large option (B) H(w) gets very small is correct.

It is defined as the function that rapidly increases and the value of the exponential function is always positive. It denotes with exponent y = a^x

where a is a constant and a>1

As we know, It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have a graph shown in the picture.

From the graph:

H(w) represents the vertical axis or y-axis and w represents the horizontal axis or x-axis.

H(w) is decreasing as the w increasing

Thus, from the graph of H(w) and w, H(w) gets very small when w gets very large option (B) H(w) gets very small is correct.

Step-by-step explanation:

Let the width of the pool deck be x.

We have equation:

1)

2)

Correct choice is B

The width of the pool deck is 10 feet (x = 10).

So, the answer is option B: 10 ft.

Here, we have to find the width of the pool deck, we need to calculate the total area occupied by the pool and the deck and then find the value of x that makes the total area equal to 1,408 square feet.

First, let's calculate the area of the pool.

The pool is 12 feet by 24 feet:

Area of the pool = Length × Width

Area of the pool = 12 ft × 24 ft

Area of the pool = 288 ft²

Now, we want to add the deck around the pool.

The length and width of the entire area (pool + deck) will be (12 + 2x) feet and (24 + 2x) feet, respectively, because we add x feet to both sides of the pool.

Area of the entire area (pool + deck) = (12 + 2x) ft × (24 + 2x) ft

We want this area to equal 1,408 square feet:

(12 + 2x) ft × (24 + 2x) ft = 1,408 ft²

Now, we can solve for x:

(12 + 2x) × (24 + 2x) = 1,408

Expand the equation:

288 + 48x + 24x + 4x² = 1,408

Combine like terms:

4x² + 72x - 1,120 = 0

Now, let's solve this quadratic equation for x.

We can either factor it or use the quadratic formula:

Using the quadratic formula: x = (-b ± √(b² - 4ac)) / 2a

where a = 4, b = 72, and c = -1,120.

x = (-(72) ± √(72² - 4 * 4 * -1,120)) / 2 * 4

x = (-72 ± √(5,184 + 17,920)) / 8

x = (-72 ± √23,104) / 8

x = (-72 ± 152) / 8

Now, we have two possible solutions:

x = (-72 + 152) / 8

x = 80 / 8

x = 10

x = (-72 - 152) / 8

x = -224 / 8

x = -28

Since we are interested in a positive width for the deck, the width of the pool deck is 10 feet (x = 10).

So, the answer is option B: 10 ft.

The area of a shape is the amount of space on the shape

The area of the shape is 110 unit square

From the complete question, the composite shape has:

The area of the rectangle is:

Area = 10 * 9 = 90 unit square

The area of the triangle is:

Area = 0.5 *10 * 4 = 20 unit square

So, the area of the figure is:

Total = 90 + 20

Total = 110 unit square

Hence, the area of the shape is 110 unit square
