A club with 12 members is to choose three officers president vice-presidents and secretary-treasurer if each office is to be hel
lesya692 [45]

Answer:

12P3 = 1320

Step-by-step explanation:

How you need select three persons of a group of twelve persons, but in the selection each member of the group has a different position, then you need use a permutation

Permutation is defined how

nPr = \frac{n!}{(n-r)!}

In our case n = 12 and r = 3

Thus

12P3 = \frac{12!}{(12-3)!}

12P3 = 1320

Will give Brainliest to whoever answers first!
lapo4ka [179]

Answer:

solid...(-3,0)(-4,-1)...shaded below the line

slope = (-1-0) / (-4-(-3) = -1/(-4 + 3) = -1/-1 = 1

y = mx + b

-1 = 1(-4) + b

-1 = -4 + b

-1 + 4 = b

3 = b

this line is : y < = x + 3 <== (thats less then or equal)

====================

solid...(1,1)(2,-1)...shaded below the line

slope = (-1-1) / (2-1) = -2/1 = -2

y = mx + b

1 = -2(1) + b

1 = -2 + b

1 + 2 = b

3 = b

Highlighter pens cost $3. 86 per set at an office supply store. Which equation can be used to determine the price, P, of n sets
Leona [35]

Answer:

Total = ($3.86)n, but it ids not among the answer options.

Step-by-step explanation:

P would be equal to the price per pen set ($3.86) times the number of pen sets sold, n.

Total, P = ($3.86)n

I translated the paragraph into these options:

n = 3. 86P     No, n = P/3.86

P = 3. 86/n    No, P = 3.86n

n = 3. 86/P    No, n = P/3,86

P = 3. 86n.

A batch of snack mix made of dried fruit and nuts contain 744G of nuts the ratio of nuts to dried fruit by weight is 12 to 13 ho
Bezzdna [24]

In a bag of snack mix:

n = nuts       d = dried fruit

n = 744g        d = ???g

Ratio Nuts/Dried fruit = 12/13

This basically means that if the mix was divided in 25 parts, 12 parts would be nuts and 13 would be dried fruits

If 744 is 12 parts then 744/12 is 1 part

744/12 = 62

1 part = 62g

there are 13 parts of dried fruit

13 x 62 = 806

744g of nuts + 806g of dreid fruit = 1550g

Answer: A batch of snack mix weigh 1550g, or 1.55kg

hope it helps :)
