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

or

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

or

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

The following two-way table describes student's
guajiro [1.7K]

P ( work/ senior ) = 0.14

The attached table

required

P ( work/ senior )

This is calculated using:

P ( work/ senior ) = n ( work/ senior )/ n ( senior ).

n ( work/ senior ) = 5

n ( senior ) = 25 + 5 + = 35

So:

P ( work/ senior ) = 5/35

P ( work/ senior ) = 0.14

Add 25+5+5 (because that is all the numbers in the 'Seniors' row) and then take the 5 that is in the 'Work' column and put that over 25. (5/25 fraction as a percent is 14).
