Answer:

F = 6

Step-by-step explanation:

find the constant of variation (k) first by using this formula:

f = k/d

plug in given info to find k:  3 = k/4 so k = 12

use 12 to find F:  F = 12/2

How can you determine if you need to use a combination or permutation to count the number of outcomes? Which will usually have m
Nadya [2.5K]

Answer with Step-by-step explanation:

Permutation : It is an arrangement of r elements out of n elements.

Combination : it is a selection of r element out of n elements .

Suppose we have a set

S={1,2,3}

If two elements are taken at a time then

Using permutation formula

Total number of outcomes=3P_2

Total number of outcomes=\frac{3!}{(3-2)!}

Total number of outcomes=3!=3\times 2\times1=6

Using combination formula

\binom{n}{r}=\frac{n!}{r!(n-r)!}

Total number of outcomes=\binom{3}{2}=\frac{3!}{2!1!}

Total number of outcomes=\frac{3\times2!}{2!}

Hence, total number of outcomes=3

Total number of outcomes determined by permutation have more outcomes.

Because permutation is an arrangement of elements  therefore, it consider order of arrangement of element   but combination is a selection of elements it does no consider order of elements

Arrangements of two elements out of 3 elements

{1,2},{2,3},{2,1},{3,2},{1,3},{3,1}

By using combination if two elements taken at a time then combination

{1,2},{2,3},{1,3}

Pi x 36 - 16<br> Need help on this please answer appropriate.
Bad White [126]

Answer:

To do this question, we must first convert Pi to a decimal form, as shown below:

Pi = 3.14

So then our equation becomes:

3.14 x 36 - 16

We still need to remember PEMDAS.

Parentheses, Exponents, Multiplication, Division, Addition and Subtraction.

So according to PEMDAS, we need to do 3.14 x 36, which equals 113.04

Now we have to do:

113.04 - 16 = 97.04

Our answer is 97.04
