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)

complete the similarity statement

They can’t be similar. Similar triangles have congruent corresponding angles, and two angles are given on each. Neither of those correspond to another on the opposite triangle. Basically, there’s no way to have three congruent angles, so they aren’t similar.

Write and solve an equation to find the missing dimension of the prism.

Volume = 1620 cm3

h

9 cm 9 cm

Equation:

Height:

cm

**Height** of prism is 20 cm

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

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.

**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.**
