Ronch [10]3 years ago

There are 12 cards with different letters & patterns. The probability of randomly choosing [random card] is #[random card]/total cards.

Think of that as ratio as a %chance or probability of written as P(X). The question says to write the %chance as a fraction.

1) 2/12 = 1/6
2) 2/12 = 1/6
3) 0/12 = 0
4) 12/12 = 1
5) This is tricky. M & T would imply one card with both letters on it. 0/12 = 0
6) 4/12 = 1/3
7) 6/12 = 1/2
8) 5/12
9) 3/12 = 1/4
10) 8/12 = 2/3
11) 10/12 = 5/6
12) Odds = [favorable]:[unfavorable] = 5:7

Which equation has the least steep graph?
MAVERICK [17]

Answer:

y=\frac{1}{4}x+6

Step-by-step explanation:

y=\frac{1}{4}x+6 is the least steeped graph

  1. The greater the slope, the steeper the line.
  2. Also you use the absolute values of the slopes when determining the steepness.
  • So here it would be: \frac{3}{4},7,\frac{1}{4},2
  • Now, arrange them from least to greatest: \frac{1}{4},\frac{3}{4},2,7

As you can see, \frac{1}{4} is the smallest number/slope.

Hope this helps!
