Answer: 
Step-by-step explanation:
1) Add () to the equation: 
2) Multiply: 
3) Divide: 
4) Subtract: 
5) Add: 
The values on the horizontal axis are:
at 0 = 64
at one standard deviation (lower, upper) = (60.5 , 67.5)
at two standard deviation (lower, upper) = (57 , 71)
at three standard deviation (lower, upper) = (53.5 , 74,5)
B. P(x > 71) = 1 - P(x < 71) = 1 - P[z < (71 - 64)/3.5] = 1 - P(z < 2) = 1 - 0.97725 = 0.02275
Therefore the no of plants taller than 71 inches will be approximately 0.02275 * 3000 = 68
Answer:
After 4 hours
Step-by-step explanation:
4h = 2(2) + 6(h - 2)
4h = 4 + 6h - 12
4h = 6h - 8
2h = 8
h = 4
For a circle with center (h,k) and radius, r
the equaiton is
so
center=(5,2), radius=3
Answer:
x - y = 3
2x - y = 2
Step-by-step explanation:
x = 3 + y
2(3 + y) - y = 2
6 + 2y - y = 2
y = 2 - 6
y = -4
x = 3 + (-4)
x = 3 - 4
x = -1
