Answer:


Step-by-step explanation:
You need to take the payment and substract $1 from them, corresponding to the bet cost. With this in mind, you will win $1 with probability 18/38 = 9/19 and you will lose $1 with probability 20/38 = 10/19. With this in mind, the distribution of X is given by the following probability mass function, with range {-1,1}


Answer:
3159.853 km
Step-by-step explanation:
The question says a square has an area of 9,984,670 km^2, which means that all sides are the same length. So you can use the equation:
9984670 = (x)(x) which rearranges to 998470 = x^2
get the square root and you get:
x = 3159.853 km
Answer:

Step-by-step explanation:
Take two points from the graph
(0,24) and (6,12)
Find the slope
The formula to calculate the slope between two points is equal to

substitute

---> is negative because is a decreasing function
Find the equation of the line in slope intercept form

we have

Note: The y-intercept is given (0,24)
substitute

<span>4 + 3 + 7 ? 7 + 0 +7
</span>4 + 3 + 7 = 14
7 + 0 +7 = 14
so
4 + 3 + 7 = 7 + 0 +7
answer
<span>D. =</span>
