Answer:
a) 21%
b) 45.5%
c) 26.4%
Step-by-step explanation:
Given the supplied information, a table of probabilities can be constructed. (See the attachment.) The numbers across the bottom reflect the given ratios of customers selecting the different gas types. The numbers in the cells are those bottom numbers multiplied by the percentage that fill the tank (or not). The numbers on the right are the sums of the numbers in each row.
a) The top center cell in the table answers this question. It it the product ...
p(plus)×p(fill | plus) = 0.35×0.60 = 0.21 = 21%
__
b) The sum on the right answers this question:
p(fill) = 45.5%
__
c) The ratio of the first column number (12%) to the row sum for Fill (45.5%) answers this question:
p(regular | fill) = 12%/45.5% ≈ 26.4%
Answer:
The quantity of water drain after x min is 50
Step-by-step explanation:
Given as :
Total capacity of rain barrel = 50 gallon
The rate of drain = 10 gallon per minutes
Let The quantity of water drain after x min = y
Now, according to question
The quantity of water drain after x min = Initial quantity of water ×
I.e The quantity of water drain after x min = 50 gallon ×
or, The quantity of water drain after x min = 50 gallon ×
Hence the quantity of water drain after x min is 50 Answer
Answer:
(-9, -26)
Step-by-step explanation:
y = (x - 1)2 - 6 and y = 4x + 10
Since they are both y =, you can set the two equations equal to each other:
(x - 1)2 - 6 = 4x + 10
2x - 2 - 6 = 4x + 10
-2 - 6 = 2x + 10
-8 = 2x + 10
2x = -18
x = -9
Check:
y = (x - 1)2 - 6
y = (-9 - 1)2 - 6
y = -18 - 2 - 6
y = -26
y = 4x + 10
y = 4 (-9) + 10
y = -36 + 10
y = -26
The answer to these equations is (-9, - 26). If you graph this, this is the point where the two graphs intersect.
