Answer:
The expected number of days per week the captain can leave port is 4.05.
Step-by-step explanation:
We are given the following distribution:
What is the expected number of days per week the captain can leave port.
We multiply each outcome by its probability. So
The expected number of days per week the captain can leave port is 4.05.
Answer:
Step-by-step explanation:
Let the number be x
- 45% of x = 165
- x*45/100 = 165
- x = 165*100/45
- x = 366.666666
Answer:
(x, y) = (77/240, -3/10)
Step-by-step explanation:
It is convenient to write the equations in standard form.
Multiplying the first equation by 21 gives ...
21y = 24x -14
Multiplying the second equation by 8 gives ...
24x +9y = 5
Then the system of equations in standard form is ...
Subtracting the first from the second, we get ...
(24x +9y) -(24x -21y) = (5) -(14)
30y = -9
y = -9/30 = -3/10
Substituting this into the second equation, we have ...
24x +9(-3/10) = 5
24x = 7.7 . . . . . . . add 27/10
x = 7.7/24 = 77/240
The solution is (x, y) = (77/240, -3/10).
Answer:
<h2>x = 36°</h2>
Step-by-step explanation:
We know: the sum of the angles in any quadrilateral is 360°.
Therefore we have the equation:
108 + 108 + 2x + 2x = 360 <em>cobine like terms</em>
(108 + 108) + (2x + 2x) = 360
216 + 4x = 360 <em>subtract 216 from both sides</em>
4x = 144 <em>divide both sides by 4</em>
x = 36
