Step-by-step explanation:
Answer:
31 bottles
Explanation:
First, we need to convert 4.8 cm to meters, so taking into account that 100 cm is equivalent to 1 m, we get:
Now, to know the number of bottles of nail polish that would fit on the shelf, we need to divide the length of the shelf by the width of the bottles, so:
Therefore, the best approximation is 31 bottles.
Answer:
a) P(79 <= P <= 81) = 0.9968
b) P( X > 81 ) = 0.0002
Step-by-step explanation:
mean value = 75 GPa
standard deviation = 1.7 GPa
<u>a) Determine P(79 <= P <= 81) </u>
given that : n = 25
attached below is the detailed solution
P(79 <= P <= 81) = 0.9968
<u>b) Determine how likely the sample mean diameter will exceed 81 </u>
given that n = 36
mean diameter = 81
P( X > 81 ) = 0.0002
Step-by-step explanation:
I just eyeballed it.
<h3> Answer:</h3>

Answer:
There is a 90.32% probability that the cake was baked by Doug.
Step-by-step explanation:
We have these following probabilities:
A 70% probability that Doug bakes the cake.
A 30% probability that Jeremy bakes the cake.
A 40% probability that a cake baked by Doug gets a thumbs up.
A 10% that a cake baked by Jeremy gets a thumbs up.
One cake was selected at random on 10/01/2014 and got a "thumbs up".
1. Find the probability that the cake was baked by Doug.
The probability that a baked cake gets a thumbs up is:
Of those, 0.7*0.4 = 0.28 are baked by Doug.
So the probability is:
There is a 90.32% probability that the cake was baked by Doug.
