The probability of senior taking the bus = 0.1 .

Probability is the study of likeliness of an event to occur. It has a range from 0 to 1. 0 means uncertainty and 1 indicates certainty.

It is given that

Sophomore , Junior and Senior probability table , if they drive to the school , Take the bus or walk.

It has been asked to determine the probability if senior take the bus

The favorable outcomes of this event is 5

The total outcome of this event is 5 + 20+25 = 50

The probability = Favorable Outcome / Total outcome

Probability = 5 / 50

P(Take the bus | Senior)  = 1/10 = 0.1

Therefore the probability of senior taking the bus = 0.1 .

The equation of the line is:

[tex]y -1= 5(x - 2)[/tex]

Step-by-step explanation:

Given

Pass through [tex](2,-1)[/tex]

Parallel to: [tex]y= 5x - 2[/tex]

Required

Determine the equation in point slope form

An equation has a general form:

[tex]y = mx + c[/tex]

Where:

[tex]m = slope[/tex]

Compare: [tex]y = mx + c[/tex] to [tex]y= 5x - 2[/tex]

we have:

[tex]m = 5[/tex]

Since the line is parallel to [tex]y= 5x - 2[/tex], then they have the same slope of 5

The line equation is then calculated using:

[tex]y -y_1= m(x - x_1)[/tex]

Where

[tex]m = 5[/tex]

[tex](x_1,y_1) =[/tex] [tex](2,-1)[/tex]

So, we have:

[tex]y -1= 5(x - 2)[/tex]

Answer:

$2.50X > $25

Step-by-step explanation:

the cost times the unknown will be less or equal to$25

The inequality function to  represent the relationship between the amount of money should be considered as the $2.50X > $25.

Since

Jinan has $25 dollars to spend on drinks for the class party.

And, A case of drinks cost $2.50.

So here the inequality function should be $2.50X > $25

Here the cost should be less or equivalent to 25.

Answer:

Due to lack of parenthesis, the function can be written one of three ways:

g(x) = (x+1)/(x-2)

g(x) = (x +1)/x - 2

g(x) = x + 1/x - 2

It is also unclear if you are doing function composition, or multiplication;

I am also assuming you are plugging -3 into function h;

so then h(-3) = 4 - -3 = 4 + +3 = 7

In the first case you get 8/5

in the second case you get 8/7 - 2 = 8/7 - 14/7 = -6/7

in the third case you get 7 + 1/7 - 2 =  5 and 1/7 = 36/7

Answer:

16.66%

Step-by-step explanation:

175-150= 25/week increase

now to find what that represents as a percent:

175/150 = x/100  cross multiply

150x = 17500 divide both sides by 150

x = 116.66 *** but!!! we now have to remember we started with a "full" salary - this is an increase.

So, 166.66 - 100 = 16.66

16.66%  Are you asked to round your answer to a whole percent? Of so, you might round that to a 17% increase (though this is not as precise as the decimal).

Answer:

Step-by-step explanation:

Let us all know that in order to find the midpoint of a segment we can use the midpoint formula

(x1+x2/2, y1+y2/2)

now let us put in the values into the formula

(-2+12/2, 18-10/2)

now lets simplify

(10/2, 8/2)

(5,4)
