Here is the histogram of a data distribution. All class widths are 1.

stich3 [128]

The median of the data is 5 if the all class widths are 1, option (C) is correct.

<h3>What is the median?</h3>

A median is a middle number in a series of numbers that have been arranged to lift, and it might be more informative of the set of data than the average. When there are extremes in the sequences that might affect the average of the numbers, the median is sometimes employed instead of the mean.

In the histogram, 15 data values are given:

1, 2, 2, 3, 3, 3, 4, 5, 6, 6, 7, 7, 7, 8, 9

The mid-value is 5 which is on the 8th place

Thus, the median of the data is 5 if the all class widths are 1, option (C) is correct.

Triangles T1 and T2 are congruent.

Inessa [10]

The single transformation that can be used to map T₁ onto T₂ is Rotate T₁ 180° about the origin.

<h3>What transformation would map T₁ onto T₂?</h3>

When a shape is rotated 180° about the origin, it means that the points go from (x, y) to (-x, -y).

The points on T₁ if rotated 180° about the origin would go from:
(-2, -2) to (2, 2)

(5, -6) to (-5, 6)

(5,0) to (-5, 0)

These are the points of T₂ so the way to map T₁ on T₂ is to use a 180° about the origin.

Select the correct answer.

damaskus [11]

Answer:

None of the above.

Step-by-step explanation:

Let us check each of the answer choices one bye one.

Choice A: $y+41=(31*2)+77x$

solving for y we get:

$y=77x+21,$

which is not equal to our function h(x).

Choice B: $y=317+77x+41$ .

This gives $y=358+77x,$

which is not equal to our function h(x).

Choice C: $x+41=(31*2)+77x$ and $y=31x+77x-41$ .

The first expression does not contain y, thus it is not equivalent to h(x). The second equation already gives the value of y , and we see that it is not equal to h(x).

Therefore we conclude that none of the choices given are correct.

Find the value of each variables in the parallelogram

Ksju [112]

Answer:

C = 6

D = 10

Step-by-step explanation:

C + 5 = 11

C + 5 -5 = 11 -5

C = 6

D + 4 = 14

D + 4 -4 = 14 -4

D = 10

A one-way flight from Dallas to Atlanta is "150x − 100" miles. Find a single expression that represents the distance for a round

Aleonysh [2.5K]

One way distance is 150x-100
so for roundtrip it is 2(150x-100)
