A random sample of 30 college students is selected. Each student is asked how much time he or she spent on homework during the previous week 18, 25, 23, 21, 20, 20, 19, 18, 15, 16, 23, 15, 21, 22, 17, 20, 25, 19, 19, 18, 16. 15, 19, 21, 25, 23, 16, 18, 25, 22 Construct a frequency distribution for the data. Type the frequency for each data value Hours Studied Freq. 15 16 17 18 19 20 21 22 23 24 25​

answer is : muchas/tipicas

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

the answer is 0.000652422
