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
Answer:
it would be 14
radius=diameter÷2=38÷2=14
Answer:
Step-by-step explanation:
Initial price is b and discount is 15%.
<u>The final price is:</u>
- b - 15% =
- b - 0.15b =
- 0.85b
Correct choices are 1 and 4
