Answer:

0.44

Step-by-step explanation:

There are 300 numbers generated. Of those 300 numbers, 146 are odd and 154 are even.

The number 8 was generated 22 times. Then there are

154 - 22 = 132 other than 8 even numbers generated.

The experimental probability of an even number other than 8 being generated is

Pr=\dfrac{132}{300}=\dfrac{44}{100}=0.44.

A bacteria triples its original population in 25 hours (A=3A0). How big will its population be in 100 hours?
jeyben [28]

Answer:

81 times the original size.

Step-by-step explanation:

AA0ktA=3A0=?=?=25hours=A0ekt

Substitute the values in the formula.

3A0=A0ek⋅25

Solve for k. Divide each side by A0.

3A0A0=e25k

Take the natural log of each side.

ln3=lne25k

Use the power property.

ln3=25klne

Simplify.

ln3=25k

Divide each side by 25.

ln325=k

Approximate the answer.

k≈0.044

We use this rate of growth to predict the number of bacteria there will be in 100 hours.

AA0ktA=3A0=?=ln325=100hours=A0ekt

Substitute in the values.

A=A0eln325⋅100

Evaluate.

A=81A0

At this rate of growth, we can expect the population to be 81 times as large as the original population.

I give you a tricky one Express 108 ×125as a product of prime factors in exponential form
lana [24]

Answer:

108 \times 125=2^2 \times 3^3 \times 5^3

Step-by-step explanation:

To express the given product (108 X 125) as a product of prime factors

Step 1: Express each of the numbers as a product of its prime factors.

108=2^2 \times 3^3\\125=5^3

Step 2: Write the product together, and combine any like terms if any

Therefore,

108 \times 125=2^2 \times 3^3 \times 5^3
