The right triangle on the right is a scaled copy of the right triangle on the left. Identify the scale factor. Express your answ

bazaltina [42]

Answer:

The images of the question are missing, I found a matching question and image online, and it is in the attachments.

Answer:

The scale factor of the triangles from the left to the right is 2

The scale factor of the triangles from the right to the left is 1/2

Step-by-step explanation:

From the image, the right triangle on the left has the following dimensions:

Hypotenuse = 10

length of one side = 10

While the right triangle on the right has the following:

Hypotenuse = 20

Length of one side = 20

From the dimensions above it can be seen that the triangle on the right has a dimension of 2 times the triangle on the left:

Left (10) × 2 = right (20)

Therefore the scale factor of the triangles from the left to the right is 2

The scale factor of the triangles from the right to the left is 1/2

Answer:

A).3222

Step-by-step explanation:

For each student, there are only two possible outcomes. Either they are from Latvia, or they are not. We are choosing students without replacement. However, since the sample size is large, we can use the binomial distribution to approximate the hypergeometric distribution.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$
