Alex earned scores of 60, 74,82,87,87,and 94 on his first six algebra tests. What is the relationship between the measures of ce

DiKsa [7]

Answer:

mean <median <mode

Step-by-step explanation:

We must calculate the measures of central tendency, which are the mode, the mean and the median.

fashion, value that is most repeated, in this case 87

median, the mean value, how is an even number, the mean is the average of these central numbers, in this case it is 82 and 87

(82 + 87) / 2 = 84.5

average, is the average of all the data, we calculate it like this:

(60 + 74 +82 +87 +87+ 94) / 6 = 80.66

Therefore, the relationship would be like this:

mean <median <mode

Which graph represents the function f(x)=−3x−2?

LenaWriter [7]

Answer:

Top left

Step-by-step explanation:

We can plug in the y intercept to find which graph has the correct one.

x = 0 is y intercept

Thus

$f(0) = -3^0-2 \\f(0) = -1-2\\f(0)=-3$

At this point we known the y intercept is -3 so both graph in the left is considerable.

Notice that the base is the negative, thus the graph would goes down. Therefore the top left would be correct.

What is true about the dilation? A large parallelogram is the pre-image and a smaller parallelogram is the image. It has a scale

kotegsom [21]

Answer:

- It is a reduction with a scale factor between 0 and 1.

- It is an enlargement with a scale factor greater than 1.

Step-by-step explanation:

1. Dilation is defined as a transformation of an image in which the size on this image changes but its shape does not change.

2. In dilation, to obtain the new dimensions of the image you must multiply the dimensions of the original image by a number called "Scale factor".

3. When the scale factor is greater than 1 it is an enlargement and when this is between 0 and 1, it is a reduction.

Find the exact value. cos150°

Aloiza [94]

ANSWER

$\cos(150 \degree) = - \frac{ \sqrt{3} }{2}$

EXPLANATION

We want to find the exact value of cos(150°).

150° makes an angle of 30° with the positive direction of the x-axis and it is also in the second quadrant.

The cosine ratio is negative in the second quadrant.

Using the unit circle,

$\cos(150 \degree) = - \cos(30 \degree) = - \frac{ \sqrt{3} }{2}$
