Answer:

2.42

Step-by-step explanation:

standard deviation= sqrt(variance)

Variance=E[X2] - E[X]2

E[X] = sum(X)/n=35/9, so E[X]2 = 1225/81

E[X2] =sum(X2)/n = 189/9 = 170/81

Variance= 476/81

Standard deviation = sqrt(476/81) ~2.42

The dashed triangle is the image of the solid triangle. The center of dilation is (-4, -4)

zhuklara [117]

Answer: The required scale factor of dilation is 3.

Step-by-step explanation: Given that the dashed triangle is the image of the solid triangle and the center of dilation is (-4, -4).

We are to find the scale factor that is used to create the dilation.

We know that the scale factor of dilation is given by

$S=\dfrac{\textup{length of a side of the dilated triangle}}{\textup{length of the corresponding side of the original triangle}}.$

From the graph, we note that

two vertices of the original triangle are (-4, -4) and (-4, -6).

And, the corresponding two vertices of the dilated triangle are (-4, -4)and (-4, 2).

So, the length of a side of the original triangle, as calculated using distance formula is

$d_1=\sqrt{(-4+4)^2+(-6+4)^2}=\sqrt{0+4}=2$

and the length of the corresponding side of the dilated triangle is

$d_2=\sqrt{(-4+4)^2+(2+4)^2}=\sqrt{0+36}=6$

Therefore, the scale factor of dilation is

$S=\dfrac{d_2}{d_1}=\dfrac{6}{2}=3.$

Thus, the required scale factor of dilation is 3.

Simplify the expression. 15k+8(11−k)

myrzilka [38]

We should solve this using the order of operations, meaning we should start by distributing the 8 in the parentheses.

15k+8(11-k)
15k+88-8k

Now, we should combine our like-terms,

7k+88

There is nothing else we can do to this equation, so it is simplified. Using the math above, we can see the simplest form of this equation is 7k+88.
