Answer:
<h2>b. -3</h2>
Step-by-step explanation:
The common difference in an arithmetic sequence:
27 - 30 = -3
24 - 27 = -3
21 - 24 = -3
18 - 21 = -3
CORRECT :)
It's constant.
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:
(x, y) = ( -4 , 4)
Step-by-step explanation:
STep 1: substitute the given value of x into the equation -7 x - 6y = 4 which will be -7 (-3 y + 8) - 6 y = 4
STEP 2: solve the equation for y so basically -7 (-3 y + 8) - 6 y will be y = 4
STEP 3:substitute the given value of x into the equation so y = 4 would be
x = -3 x 4 + 8
STEP 4: solve the equation for x. -3 x 4 + 8 which you'd end up with x = -4
