Answer:
<em>1:4</em>
Step-by-step explanation:
<u>Ratios and Fractions</u>
It's given 1/5 of the chocolates in a box contain nuts. The rest do not contain nuts. The portion that does not contain nuts is:
We need to calculate the ratio of the number of chocolates that contain nuts to the number of chocolates that do not contain nuts.
This can be done by dividing 1/5 by 4/5:
Operating:
Expressing it as a ratio: 1:4
22x23=506
hope this helps! good luck!
A.
If we take 7 paintings to be hung in 7 spaces side by side, the first space can have any one of the 7 paintings, the second space can have any one of the remaining 6 paintings (as 1 is already hung), the third space can have any one of the remaining 5 paintings (as 2 already hung)...It goes on like this.
So we have ways to arrange all the paintings from left to write. <em>(in factorial notation it is 7!=5040)</em>
B.
We use combinations rather than permutations because order doesn't matter. If we name the paintings A,B,C,D,E,F, and G, groups of 3 paintings of ABC or ACB are the same. So we evaluate using the combination formula,
We have,
C.
This is similar to part A in some ways. Any 3 pictures can be arranged in different ways. . So, 6 different ways.
ANSWER:
A) 5040 ways
B) 35 different groups
C) 6 ways
4(10*9/2) = 180. I believe that would be your answer.
The statement that is true is very obvious it will be that d will intersect the point at which the statement will obviously be d because the rest make no sense
