A news report says that 28% of high school students pack their lunch. Your high school has 600 students. How many students in your high school would you expect to pack their lunch?

Answers

first you have 600., now remember where that decimal point is and move it one space to the right where you get 60.0, or 60. So 60 equals 10% of 600, with that you divide 60 by 10 where you get 6.0 and that is 2% of 600, with this info you multiply 6 by 8 and get 48, then you add 120 (because of the 20% which is 60×2) and you get your answer 168 students in your high school pack there lunch.

Answer

Find out the how many students in your high school would you expect to pack their lunch.

To prove

Let us assume that the number of student pack their lunch be x.

Formula

$Percentage = (Part\ value*100)/(Total\ value)$

As given

A news report says that 28% of high school students pack their lunch.

Your high school has 600 students.

Percentage = 28 %

Total value = 600

Part value = x

Put in the formula

$28 = (x*100)/(600)$

$x= (28*600)/(100)$

x = 168

Therefore 168 students pack their lunch .

Describe the meaning of the y-intercept

Answers

Answer:

Step-by-step explanation:

In the equation of a straight line (when the equation is written as "y = mx + b"), the slope is the number "m" that is multiplied on the x, and "b" is the y-intercept (that is, the point where the line crosses the vertical y-axis).

Answer:

y-value at intercept = f(0), the value of the function when x = 0

Step-by-step explanation:

The "y-intercept" of a graph (any graph, not just a straight line) is the y-value obtained when x = 0. In other words, the y-intercept is the point at which the graph crosses the y-axis (whose equation is x = 0). Very often the y-intercept represents the initial (beginning) value of functions whose domains include [0, +infinity).
