We know that if (x,y) lies on the graph of a function, then (y,x) lies on the graph of its inverse.
This means you need to draw the segment with endpoints (9,1) and (2,3).
x simply equals six. This is because 4 x 6 + 5 = 5 x 6 - 1.
Hope this helps!
Answer:
20
Step-by-step explanation:
if x is 20
6x would be 120
3x would be 60
120 + 60 = 180 which checks out
180 is the degree amount of a straight line
Answer:
= 0.32
Step-by-step explanation:
Exactly $2000 final winnings is possible only in <em>one of the following two cases</em>:
1)
<em>The chosen card is marked $1000 and then red chip is selected.</em> Because red chip doubles contestant's $1000 base amount, and makes it $2000.
- Since two cards of the five cards are marked $1000, the probability of choosing $1000 marked card is
- Since three of five chips is red, the probability of choosing red chips is
Then the probability of both choosing $1000 marked card and red chip is:
× =
2)
<em>The chosen card is marked $2000 and then white chip is selected.</em> Because white chip makes the contestant's final winning remain the same as base amount, which is $2000
- Since one card of the five cards are marked $2000, the probability of choosing $2000 marked card is
- Since two of five chips is white, the probability of choosing red chips is
Then the probability of both choosing $2000 marked card and white chip is:
× =
The probability that a contestant's final winning is the sum of probabilities of these two cases:
× = = 0.32
Step 3....because a number has been added only to one side of the equation
