B - selected student is girl
- selected student is freshman is girl
- choosen girl is freshmen.
Use formula .
From the table you can see that girls that are freshmen are 4 from all 30 people, then . There are 18 girls, then
. Substitute into the formula:
.
Answer: .
Slope intercept form: y = mx + b
mx = slope
b = y-intercept
We know the y intercept is 0, so nothing will be written there.
To find the slope of this line, we can use the slope formula.
We'll use the points (1, 0) and (3, 1) to find the slope.
Now we can just plug these values into the equation to find the slope.
1 - 0 / 3 - 1
1 / 2
The slope of the line is 1/2, or 0.5.
The slope-intercept form of this line can be written as:
y = 0.5x
Because a rectangular pyramid's base is square, the cross section would be as well
