Part A: Write an algebraic expression for 6 more than 7 times a number. (5 points)
m_a_m_a [10]

The algebraic expression of the part A is 6+7x. And the verbal expression for 3*(n+8) is "the triple of the sum between the numbers n and 8".

<h3>Linear Expression</h3>

A linear expression can be represented by a line. The standard form for this equation is: y=ax+b , for example, y=2x+7.

  • Part A

First, you should choose a variable for unknow number. Here, the variable will be x. Then, 7 times a number can be represented for 7x.

The word <em>more </em>will be represented for the add symbol (+). Thus,

the algebraic expression is 6+7x.

  • Part B

The expression 3*(n+8) can be represented for the sentence:

The triple of the sum between the numbers n and 8.

Theoretical probabilities are Select one: a. the relative frequencies based on an experiment. b. the short-run relative frequenc
luda_lava [24]

Answer:

Theoretical probabilities are the long-run relative frequencies based on an experiment.

Step-by-step explanation:

Relative frequency or experimental probability is calculated from the number of times an event happens, divided by the total number of trials in an actual experiment.

With theoretical probability, you don't experiment. Instead, you use what you know about the situation to determine the probability of an event occurring.

Experimental probability approaches theoretical probability when the number of trials is extremely large.

Therefore, theoretical probabilities are the long-run relative frequencies based on an experiment.
