Answer:
Wheres the picture
Step-by-step explanation:
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:
$136.50
Step-by-step explanation:
Time and a half = 13.00 + (13 × 1/2)
Time and a half = 13.00 + 6.50
Time and a half = $19.50
If he works 7 hours of overtime, and overtime means getting paid time and a half, we would multiply 7 hours by $19.50 to find the total amount he was paid
7 × 19.50 = 136.50
In overtime, he was paid $136.50
To me this looks an equation that would fall under the commutative property of multiplication but i’m not seeing that as a possible answer so if you can i would put commutative property of multiplication:)
