A six person committee is chosen at from a group of 12 people. How many different committees are possible?

1 answer:

3 0

Since order does not matter, ie Joe, Jim, and Dave is the same as say Jim, Dave, and Joe. You would use the "n choose k" formula for unique combinations...

n!/(k!(n-k)!), where n=number of possible selections and k=selections made...

12!/(6!(12-6)!)

12!/(6!6!)

924

So there are 924 possible different committees of six people from a pool of twelve people.

Yeast , a key ingredient bread , thrives within the temperature range of 90° F to 95°F . Write and graph an inequality that repr

NeX [460]

Answer:

Please find attached the required graph of the inequality representing the temperatures yeast will NOT thrive

Step-by-step explanation:

The given parameters are;

The temperature range, y, in which yeast thrives is 90°F ≤ y ≤ 95°F

Therefore, the temperature range, y', in which yeast will not thrive is 90°F > y and y > 95°F

The graph of the inequality that represents the temperature is therefore given as shown in the attached drawing.

What Is -0.75-(-2/50)+0.4(-3/4)? Explain and answer the question please

lilavasa [31]

The answer is -1.01
I first changed the signs of the ones i could. So <span>-0.75+(2/50)+0.4(-3/4)
Then i multiplied the 0.4*-3/4 which equals -0.3
So you are left with </span><span>-0.75+(2/50)-0.3
2/50 is equal to 0.04 so now it is </span> -0.75+0.04-0.3 and the rest is simple math. Which equals -1.01
