Answer:
12 and 3.0984
Step-by-step explanation:
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
The expected value of the binomial distribution is:
The standard deviation of the binomial distribution is:
In this problem, we have that:
So
So the correct answer is:
12 and 3.0984
Answer:
(X+5)^2 + (Y-2)^2 =49
Step-by-step explanation:
Equation of the circle
(X-a)^2+(Y-b)^2= r^2
Center=(-5 ; 2) , so : a= -5 y b=2
y r=7
Answer:
36 is what you get if you break the figure up in pieces and then add them back.
2 hoses together:
15 mins = 1 pond
1 min = 1/15 pond
1st hose:
24 mins = 1 pond
1 min = 1/24 pond
2nd hose:
1 min = 1/15 - 1/24 = 1/40 pond
So 1/40 of the pond = 1 min
40/40 of the pond = 1 x 40 mins
1 whole pond = 40 mins
---------------------------------------------------------------------------------------------------
Answer: it will take 40 mins for the 2nd hose to fill up the pond alone.

Answer:
4=x
Step-by-step explanation:
y=-x+4
y=2x-8
-x+4=2x-8
+x +x
4=3x-8
+8 +8
12=3x
/3 /3
4=x
