There are 5 red pens and 10 black pens in a cup. If a person randomly selects 3 of them, what is the probability that they're al
kolbaska11 [484]

Answer:

option a)

0.286

Step-by-step explanation:

Given that,

number of red pens in cup = 5

number of black pens in cup = 10

number of pen randomly selected = 3

There are 5 red pens and 10 black pens. So there are 5 + 10 = 15 pens in all.

probability of having all red pens = (5/15 x 4/14 x 3/13)

                                                       = 2/91

probability of having all black pens = (10/15 x 9/14 x 8/13)

                                                           = 24/91

probability that all pen are of same colour = 24/91 + 2/91

                                                                      =  2/7

                                                                      ≈ 0.286

The low temperatures for 5 days was 5, -2, -11 ,0 and-3.What was the average low temperature for those days
Daniel [21]
Data:
Average (A): ?
Arithmetic mean (A.M) = 5, -2, -11, 0, -3sum of n numbers = 5

Solving:
A = \frac{AM}{n} = \frac{5+(-2)+(-11)+0+(-3)}{5} = \frac{5-2-11-3}{5} = \frac{\diagup\!\!\!\!3-11-\diagup\!\!\!\!3}{5} = \frac{-11}{5} = - 2.2

Answer:

<span>The average low temperature of these days is -2.2</span>

Find the GCF of each expression. Then factor the expression.
GaryK [48]
For finding GCF, just find the least number among them.
For example: 
a.) 6x^2 - 9 find what number that can be divided to 6. In this case, it is 2 and 3. 
You can't divide 9 by 2 so the answer in this equation would be 3.

b.) 2a^ 2 + 22a + 60 I's just the same method to use. In this case, we will use 2a^2. The factors that can be divided to 2 is (2,1). So we will choose 2 because it is the GCF of 2 and the equation is divisible by 2.
