Answer:

Step-by-step explanation:

P1 = (2000, 1000) in the form (x1,y1)

P2 = (2012, 3400) in the form (x2,y2)

m = (y2-y1 / x2-x1)

m = ( 3400-1000 ) / (2012 - 2000)

m = 2400 / 12

m = 200

y = 200x + 800

Choose all the options that are examples of volume:

Ulleksa [173]

Answer:

2. The amount of soup in a can

3. The amount of chips in a bag of chips

5. The amount of chocolate that makes up a chocolate bar.

Step-by-step explanation:

Volume is the amount that a substance or object occupies, or that is enclosed within a container, so 1 and 4 wouldn't make sense since 1 is a shadow that doesn't take up anything three dimensional, and same goes with 4.

How many five-card hands (drawn from a standard deck) contain exactly three fives? (A five-card hand is any set of five differen

VashaNatasha [74]

Answer:

4512.

Step-by-step explanation:

We are asked to find the number of five-card hands (drawn from a standard deck) that contain exactly three fives.

The number of ways, in which 3 fives can be picked out of 4 available fives would be 4C3. The number of ways in which 2 non-five cards can be picked out of the 48 available non-five cards would be 48C2.

$4C3=\frac{4!}{3!(4-3)!}=\frac{4*3!}{3!*1}=4$

$48C2=\frac{48!}{2!(48-2)!}=\frac{48*47*46!}{2*1*46!}=24*47=1128$

We can choose exactly three fives from five-card hands in $4C3*48C3$ ways.

$4C3*48C3=4*1128=4512$

Therefore, 4512 five card hands contain exactly three fives.
