Answer:
x = 4
Step-by-step explanation:
5x - 4 = 4x
- Subtract 5x from both sides of the equation.
-4 = -1x
- Divide -1 to isolate the x variable
x = 4
Answer:
-32
Step-by-step explanation:
(1-3)^5
(-2)^5
32
Volume is equal to the area of the base times the height in regular 3D shapes.
volume = πr²h = π(6²)10 = 360π = 1131.0 m³ approx.
Given:
z = (x - μ)/σ = z value
x = independent variable = 11
μ = mean = 8
σ = standard deviation = 3
Solution:
X ~ N (8, 3)
For day 1, n = 5
P (X < = 11) = P (Z < = 11 – 8 / 3/Sqrt5) = P (Z <
=2.23) = 0.987126
For day 1, n = 6
P (X < = 11) = P (Z < = 11 – 8 / 3/sqrt6) = P (Z <
=2.45) = 0.992857
For both days:
P (X <= 11) = P (X <= 11) = (0.987126) (0.992857) =
0.9801
