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:
y=(x−5)2
The graph of y is the standard parabolic, concave up curve of y=x2 shifted ("transformed") by 5 units right ("positive") on the x−axis,
The graph of y is shown below.
graph{(x-5)^2 [-10, 10, -5, 5]}
Step-by-step explanation:
The number of days of the week that January 1 falls on in leap years in any cycle of 400 years is, and months with 5 Saturdays are:
- Sunday 15 [March, June, September December]
- Monday 13 [June, August, November]Tuesday 14 [March, May, August, November]
- Wednesday 14 [February, May, August, October]
- Thursday 13 [January, May, July, October]
- Friday 15 [January, April, July, October, December]
- Saturday 13 [January, April, July, Septembe
