Answer:
0.2425 or 24.25%
Step-by-step explanation:
If the shipment of 400 components contains 68 defective and, we can estimate the probability of selecting a defective components as
68/400 = 0.17
Now, we have a binomial experiment of 25 trials and we want to compute the probability that more than 5 trials are “success” (defective component)
P(X>5) = 1 - P(X≤ 5)
Since
<em>1 - P(X≤ 5) = 1 - (P(X=0) + P(X=1) + P(X=3) + P(X=4) + P(X=5)</em> =
Answer:
Step-by-step explanation:
a). 'Per ml' cost of the small size =
=
= $0.018
'Per ml' cost of the medium size =
=
= $0.0199
'Per ml' cost of the large size =
=
= $0.01695
Therefore, expression to compare per ml cost of three containers will be,
$0.0199 > $0.018 > $0.01695
b). Least expensive way to buy the cleaner is to choose the container with least per ml cost.
Cost of 1500 ml cleaner = Cost of 1000 ml cleaner + Cost of 500 ml of cleaner
= Cost of 1000 ml cleaner container + Cost of 'n' containers of 250 ml container
Total cost of 1500 ml = $16.95 + $4.50n
= 16.95 + 2(4.5) [For n = 2]
= $25.95
c). Most expensive way to purchase 1500 ml cleaner is to choose the most expensive cleaners
Cost of 1500 ml cleaner = Cost of 'n' containers of medium size containers
= 9.95(n)
= 9.95(3)
= $29.85
Answer:
Step-by-step explanation:
Given the above right angled triangle, we would use a trigonometric ratio formula to find y.
Given angle = 30°
Hypotenuse = 6
Opposite side = y
Solve for y using the trigonometric ratio formula as follows:
Multiply both sides by 6
