Answer:
Step-by-step explanation:
How many books are there?
6+5+4+3 = 18 books total
How many are adventure books?
3
3 out of 18 books are adventure books
Robero has a 3/18 probability of choosing an adventure book.
Your teacher might want that probability in the lowest possible form. That is because it is the easiest to use and to understand.
You can do this by dividing both numbers by the "numerator" which is the first number in the fraction, (the adventure book count).
3/3 = 1
18/3 = 6
So the fraction can be reduced to 1/6.
Robero has a 1/6 chance of choosing an adventure book.
We will describe the following equation step by step:
750 + 0.2 (X-500)
We have then:
750: represents the base salary
x-500: represent the amount of sales
0.2 (X-500): represent the commission earned by sales above $ 500
Answer:
the meaning of for this situation (0.2 (X-500)) is:
total amount of commission earned
Answer: y = 4x/3 - 5/2
Step-by-step explanation:
The equation of a straight line can be represented in the slope intercept form as
y = mx + c
Where
c represents the y intercept
m = slope = (y2 - y1)/(x2 - x1)
The given line, L1 passes through A(6, - 7) and B(- 6, 2). The slope of line L1 is
m = (2 - - 7)/(- 6 - 6) = 9/ -12 = - 3/4
If two lines are perpendicular, it means that the slope of one line is the negative reciprocal of the slope of the other line.
Therefore, the slope of line L2 passing through the midpoint, M is 4/3
The formula determining the midpoint of a line is expressed as
[(x1 + x2)/2 , (y1 + y2)/2]
Midpoint, M = [(6 + -6)/2 , (- 7 + 2)/2]
= (0, - 5/2]
This means that the y intercept of line L2 is - 5/2
The equation of L2 becomes
y = 4x/3 - 5/2

Step-by-step explanation:
The percentage of yellow tint in the new mixture will be 39.1304...%
<em><u>Explanation</u></em>
A mixture of 60 liters of paint is 25% red tint, 30% yellow tint and 45% water.
So, the amount of yellow tint
liters.
Now, 9 liters of yellow tint are added to the original mixture. So, the <u>total amount of yellow tint in the new mixture</u> will be:
liters.
And the <u>total amount of the new mixture</u> will be:
liters.
So, the percentage of yellow tint in the new mixture ![=\frac{27}{69}\times 100\% = 39.1304... \%](https://tex.z-dn.net/?f=%3D%5Cfrac%7B27%7D%7B69%7D%5Ctimes%20100%5C%25%20%3D%2039.1304...%20%5C%25)
