Answer:
a) The cumulative distribution function would be given by:
x 0 1 2 3 4 5
F(X) 0.05 0.15 0.30 0.55 0.9 1
b)
And replacing we got:
Step-by-step explanation:
For this case we have the following probability distribution function given:
x 0 1 2 3 4 5
P(X) 0.05 0.1 0.15 0.25 0.35 0.1
We satisfy the conditions in order to have a probability distribution:
1)
2)
Part a
The cumulative distribution function would be given by:
x 0 1 2 3 4 5
F(X) 0.05 0.15 0.30 0.55 0.9 1
Part b
For this case we want to find this probability:
And replacing we got:
Answer:
1.0
Step-by-step explanation:
You are rounding to the nearest tenth, so you should have only 2 places remaining (0.0). So, you look to the 7 to change the 9. 7 is bigger than 5, so you round 9 up. Since 9 plus 1 equals 10, the final answer is 1.0.
Hope this helps! :)
Answer:
(x + 5)2 + 2 = 42.5
List of steps
2(x)+2(5)
2x+10
2x+10+2=42.5
2x+12=42.5
2x=42.5-12
2x=30.5
2x/2=30.5/2
x=30.5/2
x=15.25
x=15.25
Step-by-step explanation:
(x + 5)2 + 2 = 42.5
Solve (x+5)2 first
2(x)+2(5)
2x+10
Now the equation
2x+10+2=42.5
2x+12=42.5
Make 2x the subject
2x=42.5-12
2x=30.5
Divide both sides of the equation by 2
2x/2=30.5/2
x=30.5/2
x=15.25
-48, 96, -192. it is multiplied by -2 each time. hope i helped
Answer:
1.88261%
Step-by-step explanation:
Use the formula (E - T) / |T| * 100
(92 - 90.3) / |90.3| * 100
1.7 / 90.3 * 100
0.0188261 * 100
And you get a 1.88261 percent error :)
