Answer the question 1st:

1-corresponding angles=180

then,90+90=180

2-not parallel

3-not parallel

4-corresponding angles=180

x+x=180

2x=180

x=180/2

x=90degree

5-suppose x for two angles

then, same as 4 no. x + x=180

6= alternate angles are always equal.

In an experiment, there are n independent trials. For each trial, there are three outcomes, A, B, and C. For each trial, the pro

Mekhanik [1.2K]

Answer:

(B) No. A binomial probability model applies to only two outcomes per trial.

Step-by-step explanation:

The binomial probability is the probability of having $x$ sucesses on $n$ repeated trials of an experiment that can only have two outcomes. This is why it is called the binomial probability.

Since in our problem there are three possible outcomes, the binomial probability cannot be used.

The correct answer is (B)

(B) No. A binomial probability model applies to only two outcomes per trial.

Kenzie finds purple, blue, and silver space rocks while exploring, 2/3 of the rocks are purple and 3/4 of the remainder are blue

Nadya [2.5K]

Answer:

There were 36 space rocks in total.

Step-by-step explanation:

First, you need to find what fraction of the original rocks are silver.

If 2/3 are purple, then 1/3 of them are not.

If 3/4 of the remaining 1/3 are blue, then 3/4 x 1/3 = 3/12 rocks are blue.

2/3 of the rock are purple, 3/12 of them are blue, and the remaining is silver.

So, you need to do 2/3 - 3/12, then find common denominators so, 8/12 - 3/12 which = 1/12.

This means 1/12 of the rocks are silver. If there are silver rocks, you need to find a suitable equation that needs to be solved.

So:

1/12r = 3

r = 36 silver rocks

There were 36 space rocks in total.

hope this helps :)

Help me pls!

mafiozo [28]

Answer:

6 ≤ x ≤ 12

Step-by-step explanation:

Area formula

A = lw

Applied to the given rectangle, we have

A = 1.5*4x = 6x

Since 36 ≤ A ≤ 72, substituting A

36 ≤ 6x ≤ 72
6 ≤ x ≤ 12

It is viable.
