How many solutions are there to the equation x2 + 7x – 6 = 0?

two real roots

Step-by-step explanation:

x^2 + 7x – 6 = 0

We can use the discriminant

This is in the form ax^2 +bx+c=0

b^2 -4ac

If  b^2 -4ac> 0 there are 2 real roots

If b^2 -4ac = 0 there is one real root

If b^2 -4ac <0 there are two complex roots

7^2 -4(1)*(-6)

49 +24

73

Since 73 > 0 there are two real roots

the median here is 25. your lowest value is 14 and highest value is 48. to find the third quartile, find the medium number in between 25 and 48 which would be 42 i believe.

one set of data has more variation than the other. hope this !
