what is the probability of drawing two yellow marbles if the first one is placed back in the bag before the second draw. give your answer as a ratio reduced to simplest terms.

Answers

Answer 1

The probability that both marbles are yellow marbles is 1/25

How to determine the probability?

The given parameters are:

Yellow = 2

Total = 10

The probability of selecting the first yellow marble :

P(Yellow) = 2/10

When the marble is returned, we have:

Yellow = 2

Total = 10

The probability of selecting the second yellow marble :

P(Yellow) = 2/10

The required probability is:

P = 2/10 * 2/10

Evaluate

P = 4/100

Simplify

P = 1/25

Hence, the probability that both marbles are yellow marbles is 1/25

A museum has an aquarium in the shape of a right rectangular prism that is 22.9m long, 7.5m wide and 4.6m high. What is the volume, rounded to the nearest cubic meter, of the aquarium?

Answers

Answer: The volume of the aquarium = 790 cubic meters

Step-by-step explanation:

Volume of rectangular prism = length x width x height

Given: An aquarium is in the shape of a right rectangular prism that is 22.9m long, 7.5m wide and 4.6m high.

Volume = [tex]22.9\times7.5\times4.6[/tex]

i.e. Volume = 790.05 cubic meters

i.e. Volume ≈ 790 cubic meters (rounded to the nearest cubic meter)

Hence, the volume of the aquarium = 790 cubic meters (approx)

will give brainliest to right answer please help!! 15 points -A sample of a radioactive isotope had an initial mass of 370 mg
in the year 2000 and decays exponentially over time. A
measurement in the year 2008 found that the sample's mass
had decayed to 110 mg. What would be the expected mass of the
sample in the year 2017, to the nearest whole number?

Answers

Answer:

78 mg

Step-by-step explanation:

370 mg - 110 mg = 260 mg (amount decayed in the 8 total years)

260 mg ÷ 8 years = 32.5 mg decayed per year

32.5 × 9 years (years between 2008 and 2017) = 292.5 mg

370 mg - 292.5 mg = 77.5 mg, rounded to 78 mg

the expected mass of the sample in the year 2017, to the nearest whole number is 0.

What is the formula for exponential growth and exponential decaying function?

The formula for exponential growth is y = y₀.e^(kt).

The formula for exponential decay is y = y₀.e^(-kt).

Given, Initial mass(y₀) = 370 mg.

After 8 years (t = 8) the mass decayed to y₈ = 110 mg.

∴ 110 = 370.e^(-8k).

e^(-8k) = 3.36.

lne^(-8k). = ln(3.36).

- 8k = 1.28.

k = - 1.28/8.

k = - 1.6.

Now expected mass of the sample in 2017 which in 9 years from 2008 will be,

y = 110.e^(-1.6×9).

y = 110.e^(-14.4).

y = 110/e^(14.4).

y = (110/1794074.78).

y = 6.13^(-5) mg.

y = 0.0000613 mg.

Answers

Answer:

x is 30° and y is 20°.

Step-by-step explanation:

In an equilateral triangle all the angles form 60°.

1) 2x = 60

x = 60/2

x = 30°.

2) 3y = 60

y = 60/3

y = 20°.

x is 30° and y is 20°.

Answer:

y=20

x=30

Step-by-step explanation:

All the angles in an equilateral triangle is equal to 60 degrees. Knowing this, we can set up the following equations:

3y=60

2x=60

3y=60

Divide both sides by 3

3y/3=60/3

y=20

2x=60

Divide both sides by 2

2x/2=60/2

x=30
