Answer:

point slope form y-5 = -1(x-2)

slope intercept form y = -x +7

Step-by-step explanation:

We have the slope and a point, we can use the point slope form

y-y1 = m(x-x1)

y-5 = -1(x-2)

Distribute

y-5 = -x+2

This is the point slope form

We can also manipulate the equation into slope intercept form

Add 5 to each side

y-5+5 = -x+2+5

y = -x +7

When the outliers are removed, how does the mean change?

jok3333 [9.3K]

<span>In statistics, an outlier is an observation point that is distant from other observations.

Given the points
15, 23, 24, 26, 27 and 35

Notice, that the points 15 and 35 are distance from the other points and hence are outliers.

The mean of the observations including the outliers is given by
$\frac{15+23+24+26+27+35}{6} = \frac{150}{6} =25$

The mean of the observations without the outliers is given by
$\frac{23+24+26+27}{4} = \frac{100}{4} =25$

Therefore, </span>when <span>the outliers are removed, the mean remains the same.</span>

Alona has some wood cutouts of two different shapes - square and triangle. Each square cutout is 6 mm thick and each triangular

kobusy [5.1K]

Answer:

Step-by-step explanation:

Volume is a product of cross-sectional area and height and relresented as V=Ah where V is volume, A is cross-sectional area and h is height.

For the square, since each has a thickness of 6mm then for 24 of them the height will be 24*6=144 mm

Since the volume and cross sectional area of the triangle should be the same, then the height should also be the same.

Since for the triangle each has a thickness of 8mm then the number requred to achieve a height of 144 mm will be 144/8=18 stacks

Answer: Choice B

The slope is rise/run = 2/3 meaning we go up 2 and over to the right 3. For instance, moving from (0,0) to (3,2) has us move up 2 and over to the right 3.

Alternatively you can use the slope formula m = (y2-y1)/(x2-x1) to get the same result of 2/3.
