Answer:21 male drink only coffee
The probability of the probability that any person is male is 0,21
but if you need the probability of the males is 0,57
Step-by-step explanation:
number of people:100
number of males:57
number of males whos drink only coffee:21
number of males whos drink only coffee / number of people= 
Answer: 1.03% Explanation: Divide the amount of money after 1 year by his original investment.
Actual cost of the TV = $175.95
Percentage of discount given on the TV = 20%
Then
Amount of discount on the TV = (20/100) * 175.95 dollars
= 175.95/5 dollars
= 35.19 dollars
So cost of the TV after discount = (175.95 - 35.19) dollars
= 140.76 dollars
Now
Percentage of sales tax that needs to be added = 6%
Then
Amount of sales tax that needs to be added = (6/100) * 140.76 dollars
= 844.56/100 dollars
= 8.45 dollars
Then
Price of TV after adding sales tax = (140.76 + 8.45) dollars
= 149.21 dollars
So the cost of the TV after deducting the discount and adding the sales tax is $149.21
First, solve 10x + y = -20 for y: y = -20 - 10x
Next, substitute -20 -10x for y in the second equation:
-20 - 10x = 2x^2 - 4x - 16.
Rearranging, 2x^2 + 6x + 4 = 0
Simplifying, x^2 + 3x + 2 = 0
The roots of this poly eqn are -1 and -2. Therefore, x = -1 and x = -2.
One by one, subst. these x-values into y = -20 - 10x to find the corresponding y-values.
Your answers should look like this: (-1, y) and (-2, y) (different values for y).
