<span>You are given
the factors 12.34.0.74.91. The dots between the factors mean ‘to multiply’. Multiplying
12 by 34 by 0 by 74 by 91 would result to zero. The product of the given
numbers is 0. This is due to the zero property of multiplication. Any number
multiplied by zero is equal to zero. No matter how long the number you are
going to multiply it, if there is a zero between the factors, the answer will
always be zero.</span>
solution:
I choose 5 women from a pool of 10 in 10C2 ways.
I choose 5 men from a pool of 12 in 12C2 ways.
So total number of ways of choosing in 10C2 x 12C2. Now I need to arrange them in 5 pairs. This is where I have a different solution. The solution says that there are 5! ways to arrange them in pairs.
But I cant seem to understand why? My reasoning is that for first pair position I need to choose 1 man from 5 and 1 woman from 5. So for the first position I have 5 x 5 choices (5 for man and 5 for woman). Similarly for the second position I have 4 x 4 choices and so on. Hence the total ways are 5! x 5!
So I calculate the total ways as 10C2 * 12C2 * 5! * 5!. Can anyone point the flaw in my reasoning for arranging the chosen men and women in pairs.
Answer:
78.54 millimeters
Step-by-step explanation:
A=πr^2
A= 3.14 times 5 millimeter squared

Answer:
30$
Step-by-step explanation:
First you have to find the cost of one can of coffee
- 12÷6 is equal to 2 (That is the cost of one can)
- 2×15 is equal to 30$ (That is the cost of 15 cans of coffee)
I hope that's a right answer
The answer for the last one at the bottom, 5x + 17 > = 7, the answer is D. x> = -2
For the 1st one up top, the answer is B. 3.
