Answer:
42666 cases
Step-by-step explanation:
P = (Marginal Loss)/ (Marginal Loss + Marginal Profit)
P = (35)/(35+15) = 0.7
Considering a normal distribution we can find the corresponding z value by P = 0.7 (which represented the shaded area under the curve)
z = 0.5244
z = (X - Mean Sales)/Standard Deviation
-0.5244 = (X - 45000)/4450
X = 42666.42 ≅ 42666
Answer:
k=-2
Step-by-step explanation:
-1*-2=2
-1*-2=20*-2=0
-1*-2=20*-2=02*-2=-4
-1*-2=20*-2=02*-2=-45*-2=10
Answer:
Event A:15/36
Event B:18/36
Step-by-step explanation:
We can use a table for this question,the two succession are independent so we can see it as two dice rolling at one time.
Then we just need to find out the sum which is required.
Event A: 15÷36 because there are 15 sum greater than 7 and 36 total outcomes.
Event B: 18÷36
For this case we have the following equation:

Where,
I: <span>the intensity of a given sound
I0: </span><span> the threshold of a hearing intensity
</span>Substituting values in the given equation we have:
<span />

<span />Rewriting the equation we have:
<span />

<span />Then, by properties of logarithm we have:
<span />

<span />Finally we have:
<span />

<span />
Answer:
T<span />
he intensity, in decibles, [I(dB)], when I=10^8(I0) is:
