t = ⅓ ln 6
Answer:
8n-7-6n ( -*+ will be - for the term 6n)
2n-7
2n=7
n=7/2
Answer
25 square
centimeters
Step-by-step explanation:
We want to find the area of the image of a rectangle with an area of 25 square
centimeters that has been rotated and reflected in
the coordinate plane.
Recall that, rotation and reflection are rigid transformations.
This means that, the preimage and the image rectangle are congruent.
Therefore the area of the image rectangle is still 25 square centimeters
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
