Answer:
D.
Step-by-step explanation:
The line crosses the y-axis at (0,5), so we immediately eliminate B. The section of the line that is increasing begins when x is 10 and stops increasing when x is 2
Answer:
7/5 y --> y+ 2/5y
0.68y --> y - 0.32y
3/5y --> y - 2/5y
1.32y --> y+ 0.32y
Step-by-step explanation:
Pretend there is a 1 in front of each y that doesn't have a number (coefficient) in front of it. 1 = 5/5, and then just solve for the fraction expressions.
Distribute the .25 to get .25x + 1 - 3 = 28
Then simplify to get .25x - 2 = 28
Move the two to the right to get .25x = 30
Then divide to leave x: 30 / .25 = 120
X = 120
The probability is 6/120 or 1/20, which can be expressed as a percentage of 5%.
You can find this by first deciding how many possibilities there are. With a number of items being arranged in a set, the easiest way to solve this is by using the factorial function on your calculator (the button that looks like "!"). It denotes That number by all of the integers lower than it down to 1 multiplied together.
So since there are 5 letters in poker, we would use 5! or written out:
1*2*3*4*5 = 120.
Then we would have to find all of the options that start with k and end with p, of which there are exactly 6.
koerp
korep
kreop
kroep
kerop
keorp
So then we divide the number of possibles by the total number of options.
