You have 12 cards numbered as follows: 2,5,8,10,12,15,18,20,10,7,9,11. What is the probability of choosing an even number, given
ANEK [815]
Answer:
7/12
Step-by-step explanation:
Simple:
There are 12 numbers in all and only 7 even numbers
Since there are 7 even numbers the probability of rolling an even number is 7/12.
This means that there are 7 outcomes of an even number
Therefore the probability of choosing an even number
=7/12
First find the hypotenuse of the right triangle bases.
a^2 + b^2 = c^2
4^2 + 6^2 = c^2
16 + 36 = c^2
52 = c^2
2√13 = c
Triangle bases:
A = (1/2) * b * h * 2
A = (1/2) * 4 * 6 * 2
<span>A = 24 ft^2
</span>
<span>Front Rectangle: Left side Rectangle Back Side Rectangle
</span>A = 8 * 2√13 = 16√13 ft^2 A = 4 * 4 = 32 ft^2 A = 6 * 8 = 48 ft^2
24 + 32 + 48 + 16√13 = Total area = 104 + 16√13 ft^2
-15 / 20 = -0.75
-2/3 = -0.66
-9/12 = -0.75
-12/16 = -0.75
-25/30 = -0.83
Therefore B and C are the correct answers.
Answer:
156
Step-by-step explanation:
Let number of juniors be j and number of seniors be s
Thus, we can write:
<u> 236 juniors and seniors in Mr. Jay's math class:</u>
j + s = 236
Also
<u>There are 4 fewer juniors than twice the number of seniors:</u>
j = 2s - 4
Now putting equation 2 into 1, we can solve for s:
j + s = 236
2s - 4 + s = 236
3s = 240
s = 80
Hence, juniors is:
j = 2s - 4
j = 2(80) - 4
j = 156
There are 156 juniors
