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
Answer:
1/3
Step-by-step explanation: Well you have 8, 6, and 4 well 8 is more than six and six is more than four so like its in the middle. So its abut 1/3 probability that the marble you pick will be blue! Have a amazing dsy, hope this helps. Bye.
Inverse variation means y=k/x, we are given (3,6) so
6=k/3
k=18 so
y=18/x
y=18/27
y=2/3
