The scale factor is (x2)!

9×2 = 18
4 1/2 × 2 = 9

Answer: 0.5

Step-by-step explanation:

We know that the scale factor for dilation is the ratio of the side-length of the image to the side-length of the pre-image.

From the given figure, In Pre-image ΔABC , we have AC=18

In Pre-image ΔA'B'C', we have A'C'=9

Now, the scale factor will be :_

$k=\dfrac{A'C'}{AC}=\dfrac{9}{18}=\dfrac{1}{2}=0.5$

Now, the scale factor for this dilation = 0.5

A survey found that 35% of callers complain about the service they receive from a call center. Assume that the events of differe

sasho [114]

Answer:

0.336 or 33.6%

Step-by-step explanation:

It follows from the question that the probability of a complaint is 35% = 35/100 = 0.35. Let's call this probability, p.

The probability of no complaint is mutually exclusive of p since both are complements. Let's call this q. Then

q = 1 - p = 1 - 0.35 = 0.65

The distribution is a binomial distribution.

Events of each call are independent.

The probability of 2 calls with complaint out of 5 is

$\binom{5}{2}p^2 \timesq^3=10\times0.35^2\times0.65^3 = 0.336 = 33.6\%$

In spherical geometry, all points are points on the surface of a sphere. A line is a circle on the sphere whose diameter is equa

mamaluj [8]

Answer: It is not possible that two triangles that are similar and not congruent in spherical geometry.

Step-by-step explanation:

For instance, taking a circle on the sphere whose diameter is equal to the diameter of the sphere and inside is an equilateral triangle, because the sphere is perfect, if we draw a circle (longitudinal or latitudinal lines) to form a circle encompassing an equally shaped triangle at different points of the sphere will definately yield equal size.

in other words, triangles formed in a sphere must be congruent and also similar meaning having the same shape and must definately have the same size.

Therefore, it is not possible for two triangles in a sphere that are similar but not congruent.

Two triangles in sphere that are similar must be congruent.

12 + 6x -18 Helpppp!!

Eddi Din [679]

Answer:

6x - 6

Step-by-step explanation:

The only step necessary here is to simplify. We can subtract 18 from 12 since they are like terms.

6x - 6.

That's it! That's your final answer.
