Answer:
0.5217
Step-by-step explanation:
Given that:
mean
= 5.8
Using Poisson Probability formula:


![= 1-[P(X=0)+P(X=1)+P(X=2)+P(X=3)+P(X=4)+P(X=5)]](https://tex.z-dn.net/?f=%3D%201-%5BP%28X%3D0%29%2BP%28X%3D1%29%2BP%28X%3D2%29%2BP%28X%3D3%29%2BP%28X%3D4%29%2BP%28X%3D5%29%5D)
![= 1 -[\frac{(e^{-5.8}*5.8^0) }{ 0! } + \frac{(e^{-5.8}*5.8^1) }{ 1! } +\frac{(e^{-5.8}*5.8^2) }{ 2! } +\frac{(e^{-5.8}*5.8^3) }{ 3! } +\frac{(e^{-5.8}*5.8^4) }{ 4! } +\frac{(e^{-5.8}*5.8^5) }{ 5! } ]](https://tex.z-dn.net/?f=%3D%201%20-%5B%5Cfrac%7B%28e%5E%7B-5.8%7D%2A5.8%5E0%29%20%20%20%20%7D%7B%200%21%20%20%20%7D%20%2B%20%5Cfrac%7B%28e%5E%7B-5.8%7D%2A5.8%5E1%29%20%20%20%20%7D%7B%201%21%20%20%20%7D%20%2B%5Cfrac%7B%28e%5E%7B-5.8%7D%2A5.8%5E2%29%20%20%20%20%7D%7B%202%21%20%20%20%7D%20%2B%5Cfrac%7B%28e%5E%7B-5.8%7D%2A5.8%5E3%29%20%20%20%20%7D%7B%203%21%20%20%20%7D%20%2B%5Cfrac%7B%28e%5E%7B-5.8%7D%2A5.8%5E4%29%20%20%20%20%7D%7B%204%21%20%20%20%7D%20%2B%5Cfrac%7B%28e%5E%7B-5.8%7D%2A5.8%5E5%29%20%20%20%20%7D%7B%205%21%20%20%20%7D%20%5D)



∴ the probability that, in any hour, more than 5 customers will arrive =0.5217
c (cost)
m (month)
c= xm + b
$424.20= 24.95m+ $49.95
Move everything except variable on one side.
424.20 - 49.95 = $374.24
$374.25 = 24.95m
Divide by 24.95
m = 15
15 Months
Answer:
X=6
Step-by-step explanation:
5(x+2)=6x+3x−1
<u><em>Step 1: Simplify both sides of the equation.</em></u>
5(x+2)=6x+3x−14
(5)(x)+(5)(2)=6x+3x+−14(Distribute)
5x+10=6x+3x+−14
5x+10=(6x+3x)+(−14)(Combine Like Terms)
5x+10=9x+−14
5x+10=9x−14
<u><em>Step 2: Subtract 9x from both sides.</em></u>
5x+10−9x=9x−14−9x
−4x+10=−14
<u><em>Step 3: Subtract 10 from both sides.</em></u>
−4x+10−10=−14−10
−4x=−24
<u><em>Step 4: Divide both sides by -4.</em></u>
−4x / -4= −24 / −4
x=6
Answer:
1
Step-by-step explanation:
(10-(-9)*-1)
Remember that 2 negative equal a positive. So -(-9) is positive.
(10+9*-1)
Then, PEMDAS is how you should finish this.
So, 9*-1 is -9
Then, 10-9 is 1
17) 3*5 + 4 = 19
18) 2 * 3 = 6
19) 3 * 36 + 2 * 6 + 1 = 121
20) 5 * 49 + 6 * 7 = 287
21) 6 * 64 + 6 * 8 + 6 = 438
22) 1 * 81 = 81
23) 1 * 8 + 1 * 4 = 12
24) 7 * 729 + 5 = 5108
25) 1 * 1296 + 5 * 216 + 2 * 36 = 2448
26) 1 * 16 + 1 * 2 = 18
27) 4 * 3125 + 1 * 25 + 2 * 5 + 3 = 12538
