Answer:
x+4y=8 is the correct answer
Step-by-step explanation:
Step-by-step explanation:
We have it that x follows a poisson distribution.
λ is equal to 3
The poisson distribution is given by:
P(x) = e^-λ * λ^X/X!
λ = 3
X = 4
A. The question had already given us the X value to be 4
p(x = 4)
= e^-3 x 3⁴/4!
= e^-3 = 0.001
3⁴= 34
4! = 81
putting all values into p(x=4)
= .001x81/24
= 0.1680
b. for 3 good hours, we will have lamda to be;
3x3 = 9
p(x = 6)
= e^-9 * 9⁶/6!
= 0.0911
Answer:
$39
Step-by-step explanation:
60 percent of 65 dollars is 0.6 * 65 which is $39
<u>Answer</u>
1st number = x
2nd number = 4x
3rd number = x + 100
sum of three numbers = 592
x + 4x + x + 100 = 592
6x + 100 = 592
6x = 592 - 100
6x = 492
x = 492/6
x = 82
1st number, x = 82
1st number, x = 822nd number, 4x = 328
1st number, x = 822nd number, 4x = 3283rd number, x+100 = 182
check :
82 + 328 + 182 = 592

1) Solve for radius
Radius = r
2) Solve for height
Height = h
3) in calculator enter : ( 2 x 3.14 x radius squared ) + ( 2 x 3.13 x radius x height )
