The image necessary to answer this question is below in the attachment.

Answer: No.

Step-by-step explanation: For this hanger to be in equilibrium, both sides have to equal.

The diagram can be represented as

x + 1 + 1 = 1 + 1 + 1 + 1 + 1

x + 2 = 5

x = 3

So, for this hanger to work, x = 3.

Suppose that a student who is about to take a multiple choice test has only learned 40% of the material covered by the exam. Thu

Umnica [9.8K]

Answer:

There is a 52% probability that she will get it right.

Step-by-step explanation:

We have these following probabilities:

A 40% probability that the student knows the answer to a question.

A 60% probability that the student does not know the answer to a question.

If the student does not know the answer to a question, a 20% probability of getting the question right guessing.

If we choose a question at random from the exam, what is the probability that she will get it right?

40% probability that she knows the answer

60% that she has to guess, when there is a 20% probability of getting it right. So

$P = 0.4 + 0.6*0.2 = 0.52$

There is a 52% probability that she will get it right.

The exterior angles of a pentagon are (m+5)°, (2m+3)°, (3m+2)°, (4m+1)° and (5m+4)° respectively. Find the measure of each angle

olga nikolaevna [1]

Answer:

Step-by-step explanation:

Sum of exterior angles of any polygon =360°

Sum of exterior angles of polygon = 360°

m + 5 + 2m + 3 + 3m + 2 + 4m + 1 + 5m + 4 = 360

m + 2m + 3m + 4m + 5m + 5 + 3 + 2 + 1 + 4 = 360 {Combine like terms}

15m + 15 = 360 {Subtract 15 from both sides}

15m = 360 - 15

15m = 345 {Divide both sides by 15}

m = 345/15

m = 23

m + 5 = 23 + 5 = 28°

2m + 3 = 2*23 + 3 = 46 + 3 = 49°

3m + 2 = 3*23 + 2 = 69 + 2 = 71°

4m + 1 = 4*23 + 1 = 92 + 1 = 93°

5m + 4 = 5*23 + 4 = 115 + 4 = 119°
