Let x be a random variable representing the mean weight of a one-year-old Hereford bull. Then
a.) P(x < 1100) = P (z < (X - mean)/sd) = P(z < (1100 - 1150)/80) = P(z < -0.625) = 1 - P(z < 0.625) = 1 - 0.73401 = 0.2660
b.) The middle (50%) of Hereford weights will weigh the mean weight of the sample. i.e. the middle (50%) of the Hereford weights will be 1150 pounds
The given quadratic equation will not have any real solution for c<-9/4.
The given quadratic equation is:

<h3>What is a quadratic equation?</h3>
Any equation of the form
is called a quadratic equation with a≠0.
In order to have no real solution, the discriminant of a quadratic equation will be less than zero.




For
the given quadratic equation will have no real solutions.
Hence, the given quadratic equation will not have any real solution for c<-9/4.

Answer:
i think the question is incomplete but
Tina at an average contains each package of
