What is the simplified expression for the expression below?
Alika [10]
We have the expression 4(x + 8) + 5(x - 3).
First, expand the parentheses by using the distributive property.

4(x + 8) + 5(x - 3) = 4x + 32 + 5x - 15

Now combine like terms.

4x + 32 + 5x - 15 = 9x + 17

So, C 9x + 17 is the answer.

What is the product of (2i) and (5+3i)?
Evgesh-ka [11]

The value of the product expression given as product of (2i) and (5+3i) is 10i -6

<h3>How to determine the product?</h3>

The product expression is given as:

product of (2i) and (5+3i)

Rewrite the expression as:

(2i) * (5+3i)

Open the brackets

(2i) * (5+3i) = 10i + 6i^2

Evaluate

(2i) * (5+3i) = 10i + 6(-1)

This gives

(2i) * (5+3i) = 10i -6

Hence, the value of the product expression given as product of (2i) and (5+3i) is 10i -6

A food truck did a daily survey of customers to find their food preferences. The data is partially entered in the frequency tabl
lisabon 2012 [21]

A. The percentage of the survey respondents that do not like both hamburgers and burritos is <u>26.34%</u>.

B. The marginal relative frequency of all customers who like hamburgers is <u>53.66%.</u>

C. Using the conditional relative frequencies of the data point, the strongest association of its two factors shows <u>liking hamburgers and not liking burritos</u> is the case.

<h3>Data and Calculations:</h3>

The completion of the table for the data analysis is as follows:

                          Likes Hamburgers   Does not like Hamburgers    Total

Likes burritos                    29                                41                           70

Does not like burritos       81                                54                         135

Total                                  110                               95                        205

A. The percentage of the survey respondents that do not like both hamburgers and burritos is <u>26.34%</u> (54/205 x 100).

B. The marginal relative frequency of all customers who like hamburgers is <u>53.66%</u> (205 - 95)/205 X 100.

C. The conditional relative frequencies:

Likes of hamburgers = 53.66% (110/205 x 100)

Dislikes of hamburgers = 46.34% (95/205 x 100)

Likes of burritos = 34.15% (70/205 x 100)

Dislikes of burritos = 65.85% (135/205 x 100).

Thus, we can conclude that based on the conditional relative frequencies more customers of the food truck like hamburgers (53.66%) compared to those who like burritos (34.15%).
