The probability that the major of one student that is selected at random is engineering can be calculated by the total number of engineering major divided by the total number of students

p = engineering / total students
p = 300 / ( 300 + 700 + 500)
p = 0.2 is the probability of the major of one student is engineering

Answer:

17. See below

18. 750

Step-by-step explanation:

17. Since the lollipops are being sold at the same price, 50 cents, for each one sold, they make a constant amount of money. For each increase in lollipops sold, there is a constant increase in money made, and thus the situation is a linear function.

18. To solve this equation, let's say y is the money made at the convention in dollars and x is the number of lollipops sold. If the principal gave them 125 dollars before they sold any lollipops (0 lollipops sold), then 125 is the y-intercept of the function, and in the equation y=mx+b, b=125. If each lollipop costs 50 cents (half of a dollar), then for each lollipop, x, sold, .5 dollars are made and are added to the profit, y. Thus, .5 dollars is the slope. The equation then becomes:

y=0.5x+125

Now, if they need 500 dollars, y is thus equal to 500 dollars. Solving the equation:

500=0.5x+125

500-125=0.5x

375=0.5x

\frac{375}{0.5} =x

375*2=x

750=x

Thus, 750 lollipops must be sold.

your planning to build a boat. you have a sample board of wood that you want to use . the board has an area of 1/3 ft squared an
frosja888 [35]
Given:
Area of sample board: 1/3 square ft.
Weight of sample board: 1/5 lbs

We need to get the weight of the whole square foot.

1/3 square foot is only a part of the whole square foot. Its corresponding weight is 1/5 pounds. We need to divide the area by its corresponding weight to get the total weight per square foot.

1/3 ÷ 1/5 

Rules of dividing fractions:
1st fraction: 1/3 ; 2nd fraction: 1/5

1) Get the reciprocal of the 2nd fraction. 1/5 ⇒ 5/1

2) Multiply 1st fraction to the reciprocal of the 2nd fraction
1/3 * 5/1 = 5/3

3) Simplify fraction.
5/3 is an improper fraction. To simplify it, it needs to become a mixed fraction.

5/3 = 1 2/3 pounds.
