Answer:
"The quotient of two numbers is equal to the sum of the numbers" can be expressed by x/y = x + y, but the statement is false. You can't plug in any old x and y and expect the statement to be true. Just think of the equation y=10x+5.
Step-by-step explanation:
The slope of the line is positive 1
Well without even doing it you can tell its less than one here are some reasons why,
- The number we are dividing is already less than 1
- After we divided it will be even less than it already is 6x less to be exact
- It just is.
Answer:
There are 35 possible group of 3 socks from a total of 7
Step-by-step explanation:
Given
Number of unique socks = 7
Number of possible selection = 3
Required
Number of ways she can make her selection.
The question can be categorised as combination; reason being that words like "take" as used in the question points to combination or selection.
To solve this, we make use of combination formula.
nCr = nPr/r!
Where n = 7 and r = 3
By substitution, we have
7C3 = 7P3÷3!
Taking it one at a time
7P3 = 7!÷(7-3)!
7P3 = 7! ÷ 4!
7P3 = 7 * 6 * 5 * 4! ÷ 4!
7P3 = 7 * 6 * 5
7P3 = 210
3! = 3 * 2 * 1
3! = 6.
So,
7C3 = 210 ÷ 6
7C3 = 35.
Hence, there are 35 possible group of 3 socks from a total of 7
