Answer:

B) 42:28

Step-by-step explanation:

First, let's get 12:18 simplified to make it easier to compare:

12:18 -> 4:6 - > <u>2:3</u>

Now let's check it against all the options:

A) 20:30 -> 2:3 and 2:3 = 2:3

Not our answer as it is congruent (equal too, the same as, etc)

B) We can see that the first number is larger than the second number, so without doing too much math we can see this is our answer!

42:28

(it simplifes to 6:4 -> 3:2)

(we do not have to do the following as we already have an answer, but here is the math)

C) 4:6

4:6 ->

2:3 = 2:3

D) 2:3

2:3 = 2:3

If AB = BC = CA, what is m1?
Alborosie

Answer:

60°

Step-by-step explanation:

All the side lengths of the triangle have the same measurement. This makes it an equilateral triangle. By the definition of an equilateral triangle, all the angles are congruent, therefore all their measurements are the same. There are 3 total angles in a triangle, and the total sum of the angel measurements of a triangle is 180. Divide 180 with 3:

180/3 = 60

60° is your answer.

A baseball park has determined that the number of people contained in each vehicle parked in one of their lots has following dis
ryzh [129]

Answer:

Pr(No. of people > 4) = 0.10

Step-by-step explanation:

The vehicle parking has the following probability distribution

Number of People 1 2 3 4 more than 4

Probability 0.20 0.35 0.25 0.10 ?

We want to find out the probability of number of people more than 4

No.of people = 1 -> Pr(1) = 0.20

No.of people = 2 -> Pr(2) = 0.35

No.of people = 3 -> Pr(3) = 0.25

No.of people = 3 -> Pr(4) = 0.10

Pr(No. of people > 4) = ?

We know that the sum of probabilities must be equal to 1

Pr(No. of people > 4) = 1 - Pr(1) - Pr(2) - Pr(3) - Pr(4)

Pr(No. of people > 4) = 1 - 0.20 - 0.35 - 0.25 - 0.10

Pr(No. of people > 4) = 1 - 0.90

Pr(No. of people > 4) = 0.10

Therefore, the probability that more than 4 people arrive in a vehicle is 0.10.

Reflect triangle stu across line st which of these is a valid reason why the image u will coincide with j
hjlf

Answer:

4. None of the above

Step-by-step explanation:

Reflection is a type of transformation that can be used to change the orientation of a given figure or shape without changing it size and shape.

When triangle STU is reflected across ST, the image U coincides with J because the two are on the opposite side and at the same distance from ST. Therefore, J is like the image of U.
