Answer: 7(x + 5) = 2
Step-by-step explanation:
Use the variable x to represent the number
7(x +5) = 2
Answer:
7(x+5)=2 x= -33/7
Step-by-step explanation:
Josephine will receive approximately 70 advertisements in the next 100 e-mails she receives.
The possibility of an event in time is known as probability in mathematics. How frequently does the incidence occur over the course of a specific time period, in plain English?
If Josephine received 7 advertisements out of 10 e-mails, then we can say that the probability of receiving an advertisement in a single e-mail is 7/10 or 0.7.
Assuming that the probability of receiving an advertisement in an e-mail remains the same for all e-mails, we can use this probability to make a prediction about the number of advertisements she will receive in the next 100 e-mails.
The expected number of advertisements in 100 e-mails can be calculated by multiplying the probability of receiving an advertisement in a single e-mail by the total number of e-mails:
Expected number of advertisements = probability of an advertisement x total number of e-mails
= 0.7 x 100
= 70
Therefore, based on the given information, we can predict that Josephine will receive approximately 70 advertisements in the next 100 e-mails she receives.

The expression for the given phrase is 5x+11/3x+8.
The given phrase is five times the sum of a number eleven divided by three times the sum of the number eight.
An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.
Let the unknown number be x.
Five times the sum of a number eleven = 5x+11
Three times the sum of the number eight = 3x+8
So, the expression is 5x+11/3x+8
Therefore, the expression for the given phrase is 5x+11/3x+8.

is the number
The probability that he chooses trees of two different types is 0.6 or 60%.
It is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
We have a landscaper who is selecting two trees to plant.
The total number of trees he has = 5
Total ways of choosing the two trees =
= 10
Total ways of choosing one of each =
= 6
So probability:
=
= 0.6 or 60%
Thus, the probability that he chooses trees of two different types is 0.6 or 60%.

The question seems to be written incorrectly, because m(3) = 4 and that is not an option.
If instead we wanted to find m(2) (where the function has the jump) we can see that m(2) = 2, and in this case the third option is the correct one.
Here we have the graph of a piecewise function m(x), we can see that this function has a jump at x = 2 (where you can see the jump from the line with negative slope to a line with positive slope).
We want to use this graph to find the value m(3)
Notice that x = 3 belongs in the second line, just find x = 3 in the horizontal axis and then go up until you meet the graph.
At that point move to the left until you meet the y-axis at the correspondent value of m(3).
Doing that, we can see that:
m(3) = 4
That is not an option, and I think that your teacher actually should have asked to find the value of m(2), where we have the jump.
To identify the value just need to locate which of the segments has the closed circle, that is the correct option.
With that in mind we can se that m(2) = 2, so in this case the third option is the correct.
