Total people in the cafeteria = 7 + 48 + 45 = 100
There are 45 boys.
The probability would be the number of boys over the total number of people:
45/100, which simplifies to 9/20
4.428571
I know because I googled it
The answer is 3 for this question.
The answer is D) y = 3x^2 - 2, because the x is squared, making the function a quadratic function. Quadratic functions will be in the shape of a parabola (a u or upside down u).
Meanwhile any function whose degree (highest exponent of x) is one is a linear function. It will have be a straight line.
Answer: 5x3 + x2 - 2x + 5
