The modal interval would be the range of numbers that include the most number of data points.  So, looking at your information, there would be 3 numbers in the 60-69 range, 4 numbers that fall in the 70-79 range, 6 numbers that fall in the 80-89 range, and 5 numbers that fall in the 90-99 range.  The interval with more data than any other is the 80-89 range therefore making it the mode interval.

Solve the equation for y and explain.<br><br> 2y + 2(y - 2) = 5y - 3(y - 10)
Sloan [31]
2y + 2(y-2) = 5y - 3(y-10)
2y + 2y - 4 = 5y -3y +30
4y - 4 = 2y + 30
4y - 2y = 30 + 4
2y = 34
y = 34/2
y = 17

What is the solution set of the quadratic equation 3x^2 - 2x - 1 = x^2 - 6x +3​
svet-max [94.6K]

Answer:

x = -1 ± √3

Step-by-step explanation:

3x² − 2x − 1 = x² − 6x + 3

Move everything to one side.

2x² + 4x − 4 = 0

Divide by 2.

x² + 2x − 2 = 0

Solve with quadratic formula, or by completing the square.

x² + 2x = 2

x² + 2x + 1 = 3

(x + 1)² = 3

x + 1 = ±√3

x = -1 ± √3
