QUESTION POSTED AT 19/02/2020 - 03:37 PM

Probability when picking one is just number of "correct" anwsers devided by the total picking from

2 are green, 5 are blue, so 7 marbles are correct

the chance of picking one correct equals 7/10

2 are green, 5 are blue, so 7 marbles are correct

the chance of picking one correct equals 7/10

P(black socks): 24/42 or 12/21

P(black socks without replacing): 23/41. As a result, the probability of randomly picking 2 black socks, without replacement, from the basket is 12/21×23/41=276/861 or 32%. Hope it help!

Write 76% as a decimal and as a reduced fraction.

Decimal : 0.76

Fraction : 76/100, which then simplifies to 38/50, because you divide the numerator & denominator by 2. Then, you divide them by 2 again, and get 19/25.

Reduced Fraction : 19/25

2) Po messes up 4 out of every 10 moves.

So, to make this slightly easier, we're going to turn that (above) into a fraction!

Fraction : 4/10

Then, we turn it into a decimal.

To turn it into a decimal, multiply 4/10 by 10/10, so that the denominator is 100.

Fraction: 4/10 × 10/10 = 40/100

Decimal : Because the denominator is 100, all we have to do is add a decimal marking 2 places to the left of the last digit. (0.40)

Now, because we have our decimal, we simply say that the percentage is 40%.

Why? Because if the decimal is in the hundredths place, all you need to do is take the numbers on the right side of the decimal marking, and add a percentage sign to it.

~Hope I helped!~

Current worth = 10,000,000 * (1.03)^years

We must determine the years when current worth = 13,000,000

13,000,000 / 10,000,000 = 1.03^years

1.3 = 1.03^years

Taking logs of both sides:

log (1.3) = years*log(1.03)

log(1.3) / log(1.03) = years

0.11394335231 / 0.012837224705 = years

years = 8.8760113598

Roughly about 8.9 years

Space in the box = volume

volume = length x width x height

box 1 volume = 15 x 20 x 10 = 3000

how much space is left = box 2 - box 1 = 1200 inches

volume = length x width x height

box 1 volume = 15 x 20 x 10 = 3000

QUESTION POSTED AT 28/03/2020 - 12:44 PM

**Answer:**

There is a 6.67% probability that a nickel is drawn first and then a quarter.

**Step-by-step explanation:**

There are 6 coins. The sum of their values is $0.67. We need to find how many of each coin are there.

A penny is worth 1 cent.

A nickel is worth 5 cents.

A dime is worth 10 cents.

A quarter is worth 25 cents.

**To get to 67 cents, we need:**

Two pennies, a nickel, a dime and two quarters.

**So:**

**What is the probability that a nickel is drawn first and then a quarter? Assume no replacement and that all coins are equally likely.**

Initially there are 6 coins, of which 1 is a nickel. So the probability that the nickel is drawn is:

There are no replacements, so now there are 5 coins, of which 2 are quarters. So the probability that a quarter is drawn is:

.

**The probability that a nickel is drawn first and then a quarter is:**

There is a 6.67% probability that a nickel is drawn first and then a quarter.

:The similar triangles should be ABE (& not ABD as you stated) & ACD

If so, we can write the following proportion:

We know that AB =10, BE=4, AC= 10 + BC (BC =12, Given), so AC =22

Plug into the above: 10/22 =4/y===> y= (22 x 4)/10===> y =44/5 =8.8
