The mean of a data set is equal to the sum of the set of numbers divided by how many numbers are in the set.

So, start by adding the numbers to get 54.

54 will be divided by the number of numbers in the set, or 6.

54 divided by 6 is 9.

So the mean of this data set is 9.

Answer:

Step-by-step explanation:

5,7,8,10,12,12

5+7+8+10+12+12=54

54/(how many numbers there are, which is 6)=9.

Given z1 and z2 below. Calculate z1/z2 and write your answer in rcistheta form.

andre [41]

Answer:

(2/9)cis(30°)

Step-by-step explanation:

We can express the two numbers in magnitude∠angle form, then find their ratio.

|z1| = 3√((-1)² +(√3)²) = 3√4 = 6

∠z1 = arctan((3√3)/(-3)) = -arctan(√3) = 120°

z2 = 27∠90°

So, the ratio is ...

z1/z2 = (6∠120°)/(27∠90°) = (6/27)∠(120°-90°)

z1/z2 = (2/9)∠30°

<h2>○=> <u>Correct option</u> :</h2>

$\color{plum} \bold{ \tt \: \bold{C. \$20,652.00}}$

<h3>○=> <u>Steps to derive correct option</u> :</h3>

Selling price of a car = $19,000

Percentage of sales tax in the city = 8.3%

Sales tax :

$= \tt \frac{8.3}{10 \times 100} \times 1900$

$= \tt \frac{8.3 \times 19000}{1000}$

$= \tt \frac{1577000}{1000}$

$\color{plum} = \tt \$1577$

Thus, the sales tax on the car = $1577

Cost of license and title = $75

Total price of car :

= Cost price of car + Sales tax + cost of license/title

$= \tt19000 + 1577 + 75$

$\color{plum} = \tt \$20652$

Thus, the total purchase price of the car = $20,652.00

Therefore, the correct option is <em>(C) $20,652.00</em>
