Answer:

Tracie’s bus travels towards her home at an average speed of 1/2 mile per minute.

Step-by-step explanation:

The labels on the graph tell us that the independent variable, x, represents time in minutes, and the dependent variable, y, represents distance from home in miles.

Looking at the graph, we can see that the number of miles from home decreases by 1 for every two minutes.  Since the distance is decreasing, this means that the bus is getting closer to home.  Since it decreases by 1 mile every 2 minutes, this means that the speed is 1/2 mile per minute.

1. HELP Use front-end estimation to estimate the sum 8.86 + 9.43 + 5.75
marta [7]

Answer:

1. Option D.

2. Option A.

Step-by-step explanation:

1. You need to follow these steps in order to estimate the sum of 8.86 + 9.43 + 5.75:

Step 1: Add the digits in the ones places of the whole numbers (these are: 8, 9 and 5).

Step 2: Round the decimals to the nearest whole number:

0.86\approx 1\\\\0.43\approx0\\\\0.75\approx1

 Step 3: Add them together:

8+9+5+1+0+1=8+9+5+2=24

2. The procedure to estimate  the difference of 83.92-47.23 is:

83.92-\\47.23\\........\\40.00\\\ -4.00\\\ \ + 0.70\\-0.01\\...........\\+36.00\\+0\ 0.69\\..............\\36.69

Rounded to the nearest whole number:

36.69\approx 37

Which best describes the numbers satisfying the inequality x less-than 7?
vladimir1956 [14]

Answer:

x

Step-by-step explanation:

To find: inequality that describes the numbers x less-than 7

Solution:

An inequality compares two values a and b such that either one is less than i.e., a < b, greater than i.e., a > b, or simply not equal to another value i.e., a ≠ b. It describes a non-equal comparison two mathematical expressions.

Inequality that describes the numbers x less-than 7 is x

A rectangle piece of paper has a width that is 3 inches less than it's length. It is cut in half along a diagonal to create two
yarga [219]

Answer:

A. The area of the rectangle is 88 square inches.

C. The equation x² – 3x – 88 = 0 can be used to solve for the length of the rectangle.

Step-by-step explanation:

The question is incomplete. Here is the complete question.

A rectangular piece of paper has a width that is 3 inches less than its length. It is cut in half along a diagonal to create two congruent right triangles with areas of 44 square inches. Which statements are true? Check all that apply.

A.The area of the rectangle is 88 square inches.

B.The equation x(x – 3) = 44 can be used to solve for the dimensions of the triangle.

C.The equation x2 – 3x – 88 = 0 can be used to solve for the length of the rectangle.

D.The triangle has a base of 11 inches and a height of 8 inches.

The rectangle has a width of 4 inches.

If a rectangular piece of paper has a width that is 3 inches less than it's length and it is cut in half along a diagonal to create two congruent right triangles with areas of 44 square inches, the width of the rectangle will be equal to the base of the each of the triangle, and the length equal to the height of the triangle.

Let the length of the rectangular piece of paper be L. If its width is 3 inches less than it's length, then W = L-3

The base of the triangle = L-3 and the height = L

Area of the triangle = 1/2 * base * height

Area of the triangle = 1/2 (L-3)L

If the area of the congruent triangles is 44in², then;

44 = 1/2 (L-3)L

88 = (L-3)L

88 = L²-3L

L²-3L-88=0

L²-11L+8L-88=0

L(L-11)+8(L-11)=0

(L-11)(L+8)= 0

L = 11in

This shows that the height of the triangle is 11 inches.

The base of the triangle = 11-3 = 8 inches

The area of the rectangle = Length*Breadth

= 11* 8

= 88in²

Based on the calculation above, the following statements are true.

-The area of the rectangle is 88 square inches.

-The equation x² – 3x – 88 = 0 can be used to solve for the length of the rectangle.

The production department has installed a new spray machine to paint automobile doors. As is common with most spray guns, unsigh
Nesterboy [21]

Answer:

The numbers of doors that will have no blemishes will be about 6065 doors

Step-by-step explanation:

Let the number of counts by the  worker of each blemishes on the door be (X)

The distribution of blemishes followed the Poisson distribution with parameter  \lambda =0.5 / door

The probability mass function on of a poisson distribution Is:

P(X=x) = \dfrac{e^{- \lambda } \lambda ^x}{x!}

P(X=x) = \dfrac{e^{- \ 0.5 }( 0.5)^ x}{x!}

The probability that no blemishes occur is :

P(X=0) = \dfrac{e^{- \ 0.5 }( 0.5)^ 0}{0!}

P(X=0) = 0.60653

P(X=0) = 0.6065

Assume the number of paints on the door by q = 10000

Hence; the number of doors that have no blemishes  is = qp

=10,000(0.6065)

= 6065
