Remark

In order for the figure to be a parallelogram, the 2 parts of the same diagonal must be equal.

Equation

Therefore 79 - y = 2y + 22         Add y to both sides.

Solution

79 = 2y + y + 22                          Combine

79 = 3y + 22                                 Subtract 22 from both sides

79 - 22 = 3y                                 Combine like terms

57 = 3y                                         Divide by 3 on both sides

57/3 = y                                        Divide

19 = y

Answer y must be 19

Edit

For x you would have to obey the same principle.

3x + 1 = x + 27      Subtract x from both sides

3x - x + 1= 27       Combine like terms

2x + 1 = 27            Subtract 1 from both sides

2x= 27 - 1             Combine the right

2x = 26                Divide by 2 on both sides.

2x/2 = 26/2  

x = 13

I am pretty sure y would be 79

The longest side of a triangle is eight more units than the shortest side . The third side is three times the length of the shor
inysia [295]

Answer:

shortest side= x

longest side= x+8

other side= 3x

x+x+8+3x= 33

5x+8=33

5x= 25

x= 5

shortest side= x= 5

longest side= x+8= 5+8= 13

other side= 3x= 3(5)=15

Philip ran out of time while taking a multiple-choice test and plans to guess on the last 4 questions. Each question has 5 possi
belka [17]

Answer:

There is a 40.96% probability that he answers exactly 1 question correctly in the last 4 questions.

Step-by-step explanation:

For each question, there are only two possible outcomes. Either it is correct, or it is not. This means that we use the binomial probability distribution to solve this problem.

Binomial probability distribution

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

In which  is the number of different combinatios of x objects from a set of n elements, given by the following formula.

And p is the probability of X happening.

In this problem we have that:

There are four questions, so n = 4.

Each question has 5 options, one of which is correct. So

What is the probability that he answers exactly 1 question correctly in the last 4 questions?

This is

There is a 40.96% probability that he answers exactly 1 question correctly in the last 4 questions.

My guess...
