Answer:
The probability that she sees exactly 4 shooting stars in the next hour is 0.13
Step-by-step explanation:
An assumption is made that she see the shooting stars of 6 every hour based on a poisson distribution.

where m is the average per hour = 6

I believe the answer is C.
Sorry if I'm wrong but I hope this helps.
Answer:
Do pemdas, (parentheses, exponents, multiplication, division, addition and subtraction). But do whatever is first, which in this case is multiplication.
Step-by-step explanation:
Write the equation out.
105 x 2 + 66x -72 = ?
105 x 2 = 210
210 + 66x - 72
210 + 66x = 276x
276x - 72 = 204
? = 204
Answer:
k = 6
Step-by-step explanation:
Step 1: Find slope <em>m</em>
m = (4 - 8)/(-10 - 6)
m = -4/-16
m = 1/4
y = 1/4x + b
Step 2: Find <em>b</em>
4 = 1/4(-10) + b
4 = -5/2 + b
b = 13/2
Step 3: Rewrite equation
y = 1/4x + 13/2
Step 4: Find <em>k</em>
y = 1/4(-2) + 13/2
y = -1/2 + 13/2
y = 12/2
y = 6
120 / 18 = 20/3
x^3 / xy = x^2 / y
20x^2 / 3y
