Answer:
358 yds
Step-by-step explanation:
To find the area of a rectangle it is length * height
Top rectangle= 12 * 6= 72
Middles rectangle= 27 * 8= 216
For the trapezoid you can use this formula A = (a + b) * h / 2
A = (11 + 9) * 7 divided by 2
Area of the trapezoid is 70
Then add ALL the shape areas together
72 + 216 + 70= 358
Answer:
38 and 21
Step-by-step explanation:
add 12+12+15 =38
add 6+6=12
take away 15-12=3
and then add 18+3=21
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 bottom is 2 times the size of the first one
2 (2x - 9) = 14
Distribute
4x - 18 = 14
Add 18
4x = 32
Divide by 4
x = 8
