Rounded to the nearest hundredth , what is the positive solution to the quadratic equation 0=2x^2+3x-8

The positive solution to the quadratic equation is x = 1.39

Given quadratic equation is

The general quadratic equation is of form:

Now comparing the general equation with the given equation we get

a = 2 , b = 3 and c = -8

The formula to determine roots of the quadratic equation is:

On plugging in vlaues, we get

On solving we get,

x = 1.39  OR  x = -2.89  

Hence , the positive solution to the quadratic equation  is x = 1.39

f(x) = y

f(-3) = -5

step-by-step explanation:

0 and 5 minutes

step-by-step explanation:

given that one morning eight buses arrive late by the number of minutes given below:

0 8 2 6 9 2 0 7 8

write these in ascending order

0   0 2 6 7 8 8 9

in the afternoon two more buses arrive at the bus stop say by x and y minutes late.

total number of buses = 10

median = average of 4th and 5th after arranging in ascending order

since 4th entry is 6, the values of x and y should be below 6

also given 0 is the mode so either x or y or both should be 0 because then only 0 gets the maximum frequency and hence mode

thus we have

0 0 0 2 6 7 8 8 9 and another unknown entry which is below 6.

since median is 3.5, we have the unknown entry to be 5 only because then only median =( 2+5)/2

thus the after noon buses were late by 0 and 5 minutes.
