Answer:

PI rational or irrational

Example: π (Pi) is a famous irrational number.

We cannot write down a simple fraction that equals Pi. The popular approximation of 22/7 = 3.1428571428571... is close but not accurate. Another clue is that the decimal

juin [17]

Step-by-step explanation:

a. First, find the z-score.

z = (x − μ) / σ

z = (80 − 74.0) / 12.5

z = 0.48

Use a calculator or table to find the probability.

P(z < 0.48) = 0.6844

b. Find the standard deviation of the sample.

σₓ = σ / √n

σₓ = 12.5 / √4

σₓ = 6.25

Find the z-score.

z = (x − μ) / σ

z = (80 − 74.0) / 6.25

z = 0.96

Use a calculator or table to find the probability.

P(z < 0.96) = 0.8315

c. When the distribution of the population is normal, then the distribution of the sample mean is also normal.

Jessamine wants to ride her bike at least 85 miles per week. She rides to and from school 5 days per week. Her house is 6.25 mil
aalyn [17]

Step-by-step explanation:

Let's translate the verbal language to algebraic language.

She rides to and from school 5 days per week, 6.25 miles each route => 5*2*6.25 miles = 62.5 miles.

She rides additioanly around the park 2.5 miles for each trip t => 2.5*t = 2.5t

Total miles of her rides per week: 62.5 miles + 2.5t

She wants to ride minimum 85 miles => 62.5 + 2.5t ≥ 85

Then, the situation is represented by this inequality:

2.5t + 62.5 ≥ 85

You can develop it and get to several equivalent inequalities, for example:

2.5t ≥ 85 - 62.5

2.5t ≥ 22.5

t ≥ 9

Any of the four forms are equivalent and a valid answer.

Ronch [10]

Answer:

The possible combinations of two letters is 12

Step-by-step explanation:

Here, we want to count the possible combinations of two letters

Now, for the first letter any point in time, we have 4 letters to pick from,

For the second letter we have 3 letters to pick from

So therefore, we have the possible combinations as;

4 * 3 = 12

Readme [11.4K]

Answer:

4 hrs

Step-by-step explanation:

Total gallons that are in the plane = 48

Used for takeoff and landing = 7.

Remaining that is left to be used while in air = 48-7

                                                                          = 41.

maximum number of hours the plane can remain in the air= Maximum of    (  \frac{41}{10} )

So maximum of 4 hours.
