Answer:
Step-by-step explanation:
The computation of the probability is shown below:
P(die and spinner) is
= Probability of the die × probability of the spinner.
where,
Probability of the die is
= 
And for the spinner, the probability is
= 
Therefore the probability of both die and inner is
= 
=
We simply multiplied the probabilities of both die and spinner
there are 0.125 cups inside 1 fluid ounces
144 / 0.125 = 1152 (divide because you are trying to figure out how many of the volumes of the mold can fit inside the 144 fluid ounces
You can fill 1152 molds with 144 fluid ounces
Answer:
interval = [17.3948 , 20.6052]
Step-by-step explanation:
given,
random sample (n) = 45
average product lifespan = 19 years
standard deviation = 4 years
confidence interval of 99 % = ?
we know,
t* = qt(1.99/2 + 44 ) = qt(0.995,44)
t* = 2.692
so,
interval
interval = [19 - 1.6052 , 19 + 1.6052]
interval = [17.3948 , 20.6052]
