How much fencing will John need? Use 22/7 for x.

Serjik [45]

Well 22/7 is 3.14 and so on but since there is a little more than 3 you need to make sure he covers up all the fencing places... SO John will need 4 fences

I will give brainiest if correct

Natalka [10]

Its C. Add 3 and 15 which gives you 18. Then move the variable (4x) to the left. Then combine like terms which are the x’s and you should get 3x. Then divide both sides by 3. (18/3 = 6)

What is the probability of choosing a pair that contains ONLY cards labeled with the letters B, C, or F?

Nezavi [6.7K]

Answer:

$Pr = \frac{1}{6}$

Step-by-step explanation:

Given

$Cards = \{A,B,C,D,E,F\}$

$r = 2$ --- selection

Required

Probability of choosing a pair with only B, C and F

The total selection is: 36

This is calculated as thus:

$First = 6$ --- First selection can be any of the 6 cards

$Second = 6$ --- Second selection can be any of the 6 cards [No restriction]

So, we have:

$n = First * Second$

$n = 6 * 6$

$n = 36$

The pair of only B, C or F is:

$Pair = \{(B,C), (B,F), (C,B),(C,F),(F,B),(F,C)\}$

$n(Pair) = 6$

So, the probability is:

$Pr = \frac{n(Pair)}{n}$

$Pr = \frac{6}{36}$

Simplify

$Pr = \frac{1}{6}$
