5 stacks of coins that looks identical. each stack has 5 coins each. 4 of those stacks weigh the same, 1 stack has coins that we

lukranit [14]

Step-by-step explanation:

The digital scale has to be used once.

Let the coins that have normal weights are normal coins and the coins that has a weight 1 pound less are called defected coins.

5 stacks are there in which any four contains normal coins and 1 stack contains defected coins.

Took 1 coin from 1st stack, 2 coins from 2nd stack and so on..

Weigh the coins and see the result.

If the total weight is 1 pound less than the stack 1 contains defected coin.

If the total weight is 2 pounds less than the stack 2 contains defected coin.

If the total weight is 3 pounds less than the stack 3 contains defected coin.

If the total weight is 4 pounds less than the stack 4 contains defected coin.

If the total weight is 5 pounds less than the stack 5 contains defected coin.

Jerome is going to draw a marble from the bag shown below, replace it, and then draw another marble. What is the probability tha

alexira [117]

Marbles in a bag: 3 green, 4 yellow, 5 blue, 8 pink.

Event A - get a green or yellow marble
Event B - get a pink marble

Events A and B are independent because we draw a marble from a bag with 20 marbles in both cases.
$P(A)= \frac{3+4}{3+4+5+8}= \frac{7}{20} 
\\P(B)= \frac{8}{3+4+5+8}= \frac{8}{20} = \frac{2}{5}$

Probability of combined events is
$P(A) \times P(B)=\frac{7}{20} \times \frac{2}{5} =\frac{7}{50}$

diamong [38]

Answer:

6 Laps

3 laps + 6 miles = 5 laps + 2 miles.

Subtract miles over. 3 laps + 4 miles = 5 laps.

Subtract laps over. 4 miles = 2 laps.

Simplify. 2 miles = 1 lap.

Plug it in to one of the equations. 5 laps + 2 miles = Your answer.

marin [14]

Answer:

70° and 20°

let the other 2 angles be 7x and 2x

90+7x+2x=180

9x=180-90

x=90/9

x=10

7x=7x10
