Answer 1

Answer:

Answer:

f(x) + g(x) = 7x² - 4x + 2

General Formulas and Concepts:

Algebra I

Combining Like Terms

Step-by-step explanation:

Step 1: Define

f(x) = 5x² - 3x - 1

g(x) = 2x² - x + 3

Step 2: Find f(x) + g(x)

Substitute: f(x) + g(x) = 5x² - 3x - 1 + 2x² - x + 3
Combine like terms (x²): f(x) + g(x) = 7x² - 3x - 1 - x + 3
Combine like terms (x): f(x) + g(x) = 7x² - 4x - 1 + 3
Combine like terms (Z): f(x) + g(x) = 7x² - 4x + 2

A right triangle has side 9 and hypotenuse 15. Use the Pythagorean Theorem to find the length of the third side.Provide your answer below:

Answers

Answer:

Step-by-step explanation:

Pythogorean Theorem:

a squared + b squared = c squared

9 squared or 81 + ? squared = 15 squared or 225

Inverse Pythagorean Theorem:

c squared - a squared = b squared

225 - 81 = 144

sqrt (144) = 12

12 = b

Write a statistical question that might have been asked to gather the data. Then explain why it is statistical.

Answers

The statistical question could be How much time do people spend in the water park.

What is Statistics?

Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.

Hours Spent at Water Park

Hours Tally

4 4

5 5

6 3

7 4

These data could be the results of a survey whose target was to determine how many hours people spent at a water park.

The size of the sample should be the number of tally, which is 4 + 5 + 3 + 4 = 16.

And the question most likely was made at the exit of a water park, when the people were leaving the park.

Thus, the statistical question could be How much time do people spend in the water park?

It is a statistical because the survey is made to a sample of the people who went to the water park instead to all the people.

Hence, the statistical question could be How much time do people spend in the water park?
