Answer 1

Answer:

45°

Step-by-step explanation:

The angle with measure of 9x and the angle with measure of 3x are supplementary

9x + 3x = 180°

12x = 180 divide both sides by 12

x = 15

The angle with measure of 9x and angle a are supplementary as well

9x + a = 180

9×15 + a = 180

135 + a = 180 subtract 135 ftom both sides

a = 45°

Step-by-step explanation:

How do you find the sum of the first 10 terms?

To sum up the terms of this arithmetic sequence: a + (a+d) + (a+2d) + (a+3d) +

Example: Add up the first 10 terms of the arithmetic sequence:

a = 1 (the first term)

d = 3 (the "common difference" between terms)

n = 10 (how many terms to add up)

What is the sum of the first 10?

According to the DuPont 2012 Global Automotive Color Popularity Report, 23% of all cars manufactured in 2012 were white. In a random sample of 100 cars parked in long-term parking at Philadelphia International Airport, 19% of the cars were white. Identify the underlined values as parameters or statistics and give the appropriate variable. Spell out phat, x-bar, mu, sigma for the variable names. Which of the following statements istrue?

a. 19% and 23% are parameters, 100 is a statistic.
b. 23% is a parameter, 19% is a statistic.
c. 23% is a statistic, 19% is a parameter.
d. 19% and 23% are statistics, 100 is neither a parameter nor a statistic.
e. 19%, 23%, and 100 are all statistics.

Answers

Answer:

b. 23% is a parameter, 19% is a statistic.

Step-by-step explanation:

If the value is from a population, it is a parameter.

Otherwise, if the value is from a sample, it is a statistic.

23% of all cars manufactured in 2012 were white.

This is from the population(all cars), so 23% is a parameter.

In a random sample of 100 cars parked in long-term parking at Philadelphia International Airport, 19% of the cars were white.

100 is the size of the sample, which is neither a parameter, nor a statistic.

19% is from the sample of 100, so it is a statistic.

The correct answer is given by option b.

Answers

Height of prism is 20 cm

Calculation of rectangular prism:

Given that;

Volume of rectangular prism = 1620 cm³

Length = 9 cm

Width = 9 cm

Find:

Height of prism

Computation:

Volume of rectangular prism = (l)(b)(h)

So,

(9)(9)(h) = 1620

(81)(h) = 1620

h = 20

Height of prism = 20 cm
