Answer:
85 Necklaces and ----- Bracelets.
Step-by-step explanation:
500 Divided by 2 = 250, The 500 is the amount in total,The 250 is the amount of bracelets and necklaces needed for 500$ To be a accurate number for 'Sarah's ' Situation. Now 250 divided by 2 is 125. It was divided by 2 so it can be the amount the bracelets cost. Or instead of dividing to get 250, You can multiply and do 2x125=250, So them add Go on from there, Its not to hard but if you need more help I'm here!
Now for the necklace portion of it. 3x80=240, So she sold 80 necklaces. Than sold 3 more. Now you have a total of 250.
Answer:
The cosine function that is represented in the graph is:
Option B. f(x)=cos (x-pi/4)-1
Step-by-step explanation:
The parent function is cos x.
cos x at x=0 has the maximum value 1.
The graph is shifted to the right (x-pi/4) with a maximum value 0 at x=pi/4, then the graph is shifted downward 1 unit.
Then f(x)=cos (x-pi/4)-1
Please, see the attached graph:
The blue line is the parent function y=cos x
The red line is the graph given
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.
