about 40 of the boys and Walter School commute to the school by bicycle what is the probability that you must select at least four boys to find one who commute by bicycle use the table of randomly generated numbers to awnser the question the numbers 0 to 3 represent boys who commute to school by bicycle and the number 4 to 9 represent boys who do not commute by bicycle ​

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

what i would say the best answer is a. 40.5

114 plus 113 times 2 and 114 times 3
