7 Hours on Average
add up all the hours and you get 35
then divide 35 by the number of given hours which is 5
35/5 = 7
so the average amount of hours slept was 7
Answer:
7 hours
Step-by-step explanation:
To find this average, add up the five data points given and divide your result by five (5):
(7 + 9 + 5 + 6 + 8) / 5 = 35 / 5 = 7
This group of students averaged 7 hours of sleep per night.
The standard form is ax² + bx + c = 0 with a, b, and c being constants, or numerical coefficients, and x is an unknown variable and if the highest power in the quation is 2 then it is a quadratic equation.
----> Quadratic Equation
y +3 = -2x² +5----> Quadratic Equation
----> Quadratic Equation
----> Non Quadratic Equation
----> Non Quadratic Equation
y = 5 x(x + 9) - 8----> Quadratic Equation
----> Quadratic Equation
Answer:
2. y + 3 = -2x^2 + 5
3. y = 2x^2 - 8x + 6
6. y = 5x (x+9) - 8
