Answer:

1/22

Step-by-step explanation:

assuming that the marbles drawn are not replaced:

P(red) = 3/12 or 1/4

P(green) = 4/11

P(blue) = 5/10 or 1/2

multiply the probabilities together:

1/4 x 4/11 x 1/2 = 1/22

Answer:

x=3130/3

Step-by-step explanation:

3,125 = 5-10 + 3x

5-10+3x=3125

3x-5=3125

3x-5+5=3125+5

3x=3130

3x/3 = 3130/3

x=3130/3

ankoles [38]

Correct question:

An elevator in a mine shaft is stopped at 25 feet below ground level. And then travels 28 feet downward. What equation can be written to find the final position in feet of the elevator in relations to ground level?

Answer:

-53 feets

Step-by-step explanation:

Initial stop point = 25 feets below ground level

Further distance traveled = 28 feets below ground level

Final position in feet = Initial stop point + further distance traveled

Note : distances or point traveled below ground level or downward is represented as negative.

Final position in feets = (-25)feets + (-28)feets

Final position in feets = - 53 feets

Over the course of a month, Katniss caught three times as many squirrels as deer. She also caught five less rabbits than squirre

NeTakaya

Answer:

She caught 10 rabbits

Step-by-step explanation:

Given

Represent Rabbits with R; Squirrels with S and Deer with D

$S = 3D$

$S = R - 5$

$S + R+ D = 10 +4D$

Required

Determine the value of R

$S + R+ D = 10 +4D$

Solve for R

$R = 10 + 4D - D - S$

$R = 10 + 3D - S$

Recall that $S = 3D$

Substitute 3D for S

$R = 10 + 3D - 3D$

$R = 10$

Hence;

<em>She caught 10 rabbits</em>
