Answer:
A. 0.199
B. 0.199
C. 6.0000
Step-by-step explanation:
Using the poisson distribution
f(x) = (e^-ht × (ht)^x)/x!
Where h = 3, t = 1 min
f(x) = [e^-(3× 1) ×(3×1)^x]/x!
f(1) = [e^-3 (3)]/1! = 3e^-3
= 0.1991
f(1)= 0.199
h = mean = np = 1 × 0.1991 = 0.1991
(b) for Poisson distribution
mean = standard deviation = h
h = np = 0.199
(c) we want to find x for
f(x) = P(X<x) = 0.95
So we check from the Poisson table the value of x for h= 3 gives a probability of 0.95
P(X< 6) = 0.95(approximately)
X = 6.0000
Answer:
-2/45
Step-by-step explanation:
-3/5 - (-5/9)
Subtracting a negative is like adding
-3/5 + 5/9
Then we need a common denominator of 45
-3/5 * 9/9 + 5/9 *5/5
-27/45 + 25/45
-2/45
Answer:
811 feet
Step-by-step explanation:
When finding height difference, you use absolute value, so everything is positive. 747+64 = 811, so your answer is 811 feet.
Hope this helps!
Answer:
x intercept = -0.25
y intercept = 4
Step-by-step explanation:
1.- remove parenthesis
y-3 = 1/2x +1
2.- adjust to equal y
y = 1/2x +1 +3
y = 1/2x +4
3.- guess values for x to try in the simplified equation.
x = -0.25 | y = 0
x = 0 | y = 4
x = 2 | y = 5
x = -2 | y = 3
x = 4 | y = 6
x = -4 | y = 2
4.- graph all coordinates (x,y). Draw a line connecting each dotted coordinate.
