Answer:
a. 81.5%
Step-by-step explanation:
The z-score for 400 is ...
Z = (X -μ)/σ = (400 -500)/100 = -1
The z-score for 700 is ...
Z = (700 -500)/100 = 2
The empirical rule tells you that 68% of the distribution is within ±1σ of the mean, and 95% is within ±2σ of the mean. Half of that first number is in the range Z = -1 to 0, and half that second number is in the range Z = 0 to +2. So, the probability you want is ...
(1/2)(68%) + (1/2)(95%) = 81.5% . . . . matches choice A
Answer:
Okay so basically your going to distribute the first equation where it says 4(2x+1) which gives you 8x+4.As you can see that is one of the answers on the right of it so then you go and answer the next problem 3(y+2) ect.If ya need help I can help you too?
Answer:
b 5/24
Step-by-step explanation:
p(a)=number of times A occurred / number of times trial was repeated
Answer:
9x+4y+2
Step-by-step explanation:
3x^2+4y+2
3x^2 = 3x*3= 9x
9x+4y+2
So the answer is 9x+4y+2
Answer:
Option A)
Step-by-step explanation:
We are given the following on the question:
where p(t) is the population of a colony.
For steady state solution we evaluate:
Thus, the steady state solution is a constant, k = 1000.
Thus, the correct answer is
Option A)
