The z-score is given by:
z=(x-μ)/σ
but
x-μ=52
thus
z=52/√84681
z=0.1787
Thus:
P(X≤52)=0.9633
Answer:
Below
Step-by-step explanation:
sin(2x) = 2 ×cos(x)× sin(x)
● sin(x) = 2 × cos(x) × sin(x)
● 2 × cos(x) = 1
● cos (x) = 1/2
So we can deduce that:
● x = Pi/3 + 2*k*Pi
● or x = -Pi/3 + 2*k*Pi
K is an integer
You first have to convert the 5 tons to pounds.
Once you have done that step you simply add.
Answer:
dryer400 and washer 490
Step-by-step explanation:
Because the numerater and denomenater are = hence 1/1, 2/2, 3/3, 4/4 5/5, 6/6, 7/7, 8/8, etc. are all = to one
hope this helps :)
