Answer:

5) r=40 gals/min

6) r= 125 mm/hr

7) $2600

8) d = 36 in

9) h= 1176 m

Step-by-step explanation:

5) r=v/r

r= 15,600 gals ÷ 390 mins

r= 40 gals/min

6) r=v/t

r= 1000mm ÷ 8 hrs

r= 125 mm/hr

7) $4500 - $1900 = $2600

8) C = Pi x d

c/Pi =d

113 in/3.14 = d

d = 36 in

9) Formula for h

h = 2 x a/b

h = 2 (84m2/12m)

h = 2 (7056/12)

h = 2(588)

h = 1176 m

X = zv-zk^5 solve for z

Aloiza [94]

Undistribute z
$x=z(v-k^5)$
divide both sides by (v-k^5)
$z= \frac{x}{v-k^5}$

Step-by-step explanation:

The Sample Space for is given as:

(1,2),(1,3),(1,4),(1,5),(1,6),(1,7),(1,8),(1,9),(1,10),(1,11)

(2,3),(2,4),(2,5),(2,6),(2,7),(2,8),(2,9),(2,10),(2,11)

(3,4),(3,5),(3,6),(3,7),(3,8),(3,9),(3,10),(3,11)

(4,5),(4,6),(4,7),(4,8),(4,9),(4,10),(4,11)

(5,6),(5,7),(5,8),(5,9),(5,10),(5,11)

(6,7),(6,8),(6,9),(6,10),(6,11)

(7,8),(7,9),(7,10),(7,11)

(8,9),(8,10),(8,11)

(9,10),(9,11)

(10,11)

n(S)=55

Event E is the Event that the two numbers are odd.

Therefore: Complement of E will be the event that any of the two numbers is even.

The Sample Space of the complement of E is:

$(1,2),(1,4),(1,6),(1,8),(1,10)\\(2,3),(2,4),(2,5),(2,6),(2,7),(2,8),(2,9),(2,10),(2,11)\\(3,4),(3,6),(3,8),(3,10)\\(4,5),(4,6),(4,7),(4,8),(4,9),(4,10),(4,11)\\(5,6),(5,8),(5,10)\\(6,7),(6,8),(6,9),(6,10),(6,11)\\(7,8),(7,10)\\(8,9),(8,10),(8,11)\\(9,10)\\(10,11)\\$
