An automotive service center would ke feedback on its customer service.
after they pay for services with a short survey on which customer service is ranked on a scale from 1 (least
satisfied) to 5 (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?
O 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
O This is question wording bias because the customer service score levels may not be clear to customers.
O This is response bias because customers may not be truthful about their experience with customer service.

Answer:

1/2

Step-by-step explanation:

Yes, I agree.

Make a graph [tex]y=-\frac{4}{5}x+\frac{2}{5}[/tex]

The point of intersection of the line with x-axis is the solution of [tex]-\frac{4}{5}x+\frac{2}{5}=0[/tex]

Multiply by 5 on both sides, get -4x + 2 = 0, x = 2/4 = 1/2

The solution is 1/2.

Answer:

Step-by-step explanation:

7(-4x - 1) = 49

-28x - 7 =49

-28x = 49 + 7 = 56

x = 56/(-28) = -2

Answer:

7 x - 4x = - 28x

7 x - 1 = - 7

-28x - 7 = 49

+7 both sides

-28x = 56

÷ - 28

x = 56/-28

x = - 2

I substitute to double check my answer:

- 4x

-4x-2 =8

7(8- 1)

7x 8 = 56

7 x - 1 = - 7

56-7= 49

Hope this helps!

Answer:

  $56.02

Step-by-step explanation:

The account balance after 10 years is given by the future value formula:

  FV = P(1 +r)^t . . . . . principal P invested at rate r compounded annually for t years

  FV = $200(1 +0.025)^10 ≈ $256.02

The amount in excess of the original investment is the interest earned:

  $256.02 -200.00 = $56.02 . . . . interest earned in 10 years

Answer:

$256.02

Step-by-step explanation:

Here is the formula: 200(1.025)^10.

The .025 is the percentage of the interest, and the 1 is the money you already have (which is 200). The ^10 is the 10 years.

If you take the (1.025)^10, you'll get an incredibly large number, 1.2800....

Take that large number and multiply it by the amount of money you originally have, $200. Then you'll get something like 256.0169... Round to the near hundredth, and you'll have 256.02

Answer:

Slope = -5/8

Step-by-step explanation:

Take 2 points from the graph where the line is. Point 1: (1 , 6). Point 2: (9 , 1).

We are going to use the formula for finding the slope of a line now.

y2 - y1/x2 - x1 = 1 - 6/9 - 1 = -5/8

Slope = -5/8

Answer:

The factors of a number are all of the numbers that will divide into that number with no remainder. The prime factors of a number are the prime numbers that must be multiplied together to give the number. For example: The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30. The prime factors of 30 are 2, 3, and 5.

Answer:

TRUE

Step-by-step explanation:

Answer:

Step-by-step explanation:

It is given

2x−3y=5

we can write it as

3y=2x−5

So we get

y=32x−5​

Substituting x=4 in the given equation

y=32(4)−5​

So we get

Y=38−5​

y=33​

By division we get

y=1

Substituting x=−2 in the given equation

y=32(−2)−5​

So we get

y=3−4−5​

y=3−9​

By division we get

y=−3

x 4       -2

y      1        -3

Now draw a graph using the points (4,1) and (−2,3)

Join the point through a line and find the value of y

(i) Based on the graph

consider x=4 on X-axis

Now the line joining the two points and a point on the Y-axis gives the value of y

Therefore,when x=4 the value of y=1

(ii) Based on the graph,

Consider y=3 on Y-axis

Now the line joining the two points and a point on the X-axis the value of x

Therefore, when y=3 the value of x=7

Answer:

Y= 9/10x - 1.2 (or 1.3)

Or - 1. 2 is 6/5

Thus, Y= 9/10x - 6/5

Answer: 80

Step-by-step explanation:

Angle FGB = 80 degrees b/c supplementary angles.

By the sum of interior angles of a quadrilateral, angle FEB = 360 - 75 - 95 - 90 = 100 degrees.

x is supplementary with this angle and is this 180 - 100 = 80.

Answer:

80 squared units.

Step-by-step explanation:

7 × 8 = 56 u squared for the triangles

you don't need to divide by two because there are two triangles.

3 × 8 = 24 u squared for the rectangle

56 + 24 = 80 squared u
