The answer is: x = -4 and y = 11/3
Answer:
15 = 9 + 5j
Step-by-step explanation:
When you want to make words become an equation, the word <em>is</em><em> </em>usually means <em>= </em>and <em>more</em><em> </em>usually means <em>+</em>.
In this case, we have 15 is 9 more than 5j.
We can rewrite this as 15 = 9 + 5j.
The image is not very much enlarged, and is slanted, so answers might be just approximate.
(a) median is 39 or 40, your choice.
(b) 3rd quartile of y looks 47 or 48
(c) variable y has more disperson, since both the extremes and the quartiles are spread out longer that those of variable x.
(d) since both halfs of the blue box (of x) and both lines outside of the box are basically equal, variable x's distribution is very much symmetric.
Sorry, cannot read question part (e) completely.
Answer:
P(x)=0.9x
Step-by-step explanation:
x(100%-10%)=x(1-0.1)=0.9x=P(x)
Answer
$0.1346
Explanation:
Find probability of each card and the value of each card and then add them together.
Probability of getting a heart = 13/52
Price of one heart =$0.30
Pay for one heart = 13/52×0.30=$0.075
Probability of getting a queen =4/52
Price of one queen =$0.55
Pay for one queen =4/52×$0.55=$0.0423
Probability of getting a queen of hearts =1/52
Price of one queen =$0.90
Pay for one queen =1/52×$0.90=$0.0173
Therefore the pay for one draw= $0.075+$0.0423+$0.0173=$0.1346
