Answer:Pois(ln(200))
Step-byy-step explanation:
Let N be the number of received calls in a day
That is
N∼Pois(λ).
0.5% = 0.5/100 = 1/200 of no calls
P(N=0)=e^−λ=1/200
-λ=e^(1/200)
λ=in(200)
Our number of calls in a day is distributed Pois(ln(200)).
To simplify and solve this equation we must follow PEMDAS.
P=Parentheses
E=Exponents
M=Multiplication (from left to right)
D=Division (from left to right)
A=Addition
S=Substraction
We begin the process.
10^3=1000
10^7=10000000
New equation looks like this:
7.2*1000/1.8*10000000
We then multiply
7.2*1000= 7200
7200/1.8=4000
4000*10000000= 40000000000
<em>So our final answer is 40000000000.</em>
Hope this helps!
P.S. I forgot this was scientific notation and I solved it a different way. But both ways give the same answer. Let me know if you want the other method.
Answer:

Step-by-step explanation:
Eric will drive between 70 -4 = 66 mph and 70+4 = 74 mph. He will <em>not</em> drive less than 66 or more than 74 mph.

Answer:
x = 4
Step-by-step explanation:
Step 1: Write equation
-72 = 3(-4x - 8)
Step 2: Solve for <em>x</em>
<u>Distribute 3:</u> -72 = -12x - 24
<u>Add 24 to both sides:</u> -48 = -12x
<u>Divide both sides by -12:</u> x = 4
Step 3: Check
<em>Plug in x to verify if it's a solution.</em>
-72 = 3(-4(4) - 8)
-72 = 3(-16 - 8)
-72 = 3(-24)
-72 = -72
