Example Question #1593 : Algebra 1

Find the mean of the following dataset: [1,7,-1,0,0,0]

Possible Answers:

$\frac{6}{7}$

$\frac{7}{5}$

$\frac{7}{6}$

Correct answer:

$\frac{7}{6}$

Explanation:

The mean is the average of all the numbers in the dataset.

Add the numbers.

1+7+(-1)+0+0+0=7

Divide this number by the total numbers in the dataset.

The answer is: $\frac{7}{6}$

Example Question #169 : How To Find Mean

Find the mean of the dataset: $[3\pi, 3\sqrt3,3]$

Possible Answers:

$\pi+\sqrt6$

$\pi+2$

$\pi+ \sqrt3+1$

$\pi+6$

$\frac{3\pi+2}{3}$

Correct answer:

$\pi+ \sqrt3+1$

Explanation:

In order to find the mean, add all the terms and divide by the number of terms in the dataset. There are three numbers in the dataset.

$\frac{3\pi+ 3\sqrt3+3}{3}$

Notice that we can pull a three out as a common factor on the numerator.

$\frac{3(\pi+ \sqrt3+1)}{3}=\pi+ \sqrt3+1$

The answer is: $\pi+ \sqrt3+1$

Example Question #170 : How To Find Mean

What is the mean given the following set of numbers? [1,1,2,0,0,0,0,0]

Possible Answers:

$\frac{1}{2}$

$\frac{4}{7}$

0,1

$\frac{3}{8}$

Correct answer:

$\frac{1}{2}$

Explanation:

The mean is the average of all the numbers in the dataset.

Add all the numbers and divide the quantity by the total amount of numbers.

$\frac{1+1+2+0+0+0+0+0}{8}= \frac{4}{8}=\frac{1}{2}$

The answer is: $\frac{1}{2}$

Example Question #171 : Statistics And Probability

What is the mean of the following dataset? $[\frac{8}{3},\frac{1}{3},\frac{6}{3}]$

Possible Answers:

$\frac{3}{5}$

$\frac{1}{5}$

$\frac{5}{3}$

Correct answer:

$\frac{5}{3}$

Explanation:

To find the mean, add all the numbers and divide by the total amount of numbers in the dataset.

$\frac{\frac{8}{3}+\frac{1}{3}+\frac{6}{3}}{3}$

Add the numerator.

$\frac{8}{3}+\frac{1}{3}+\frac{6}{3} = \frac{15}{3}=5$

Divide this by the denominator.

The mean is: $\frac{5}{3}$

Example Question #171 : Statistics And Probability

If Sam's three of the four exam grades in algebra class were 75,90,45 and he needs to average a to pass the class, what minimum score must he make on the fourth exam to pass the class?

Possible Answers:

$\textup{Sam will pass with or without Exam 4.}$

Correct answer:

Explanation:

The mean of Sam's four scores must be at least 70. Set up an equation such that the three exam scores plus the fourth exam score over four equals 70.

$\frac{75+90+45+x}{4}=70$

The variable is the unknown exam score. Multiply four on both sides to eliminate the denominator.

$\frac{75+90+45+x}{4} \cdot 4=70 \cdot 4$

75+90+45+x = 280

Solve for .

210+x = 280

Subtract 210 on both sides.

210+x -210= 280-210

Simplify.

x=70

Sam must make at least a 70 on his next exam to pass.

Example Question #1594 : Algebra 1

Find the mean of the dataset: [5,8,-3,-4]

Possible Answers:

$\frac{7}{2}$

$\frac{13}{4}$

$\frac{3}{2}$

$\frac{16}{3}$

Correct answer:

$\frac{3}{2}$

Explanation:

To find the mean of the dataset, we will need to add all the numbers and divide by the total numbers existing in the dataset.

$\frac{5+8+(-3)+(-4)}{4}=\frac{13-7}{4} = \frac{6}{4} = \frac{3}{2}$

The answer is: $\frac{3}{2}$

Example Question #174 : Statistics And Probability

Let , , and be the mean, median, and mode, respectively, of the dataset

$\left \{ 1, 2, 4, 4, 4, 5, 6, 7, 8 \right \}$ .

Which of the following correctly relates , , and ?

Possible Answers:

B< A < C

A < B < C

A = B = C

A< B = C

B = C < A

Correct answer:

B = C < A

Explanation:

The mean of a dataset is the sum of the entries divided by the number of entries. The mean of this nine-entry dataset is

$A = ( 1+ 2+ 4+ 4+ 4+ 5+ 6+ 7+ 8 ) \div 9 = 41 \div 9 = 4 \frac{5}{6}$

The median of an arranged dataset with an odd number of elements is its middle element. The dataset is arranged and has nine elements; this middle element is B = 4 .

The mode of a dataset is the element that appears the most frequently, In this set, the element 4 appears the most times, three, so C= 4 is the mode.

The correct ordering is B = C < A .

Example Question #1595 : Algebra 1

What is the mean of the dataset? $[\sqrt2, \sqrt 9, \sqrt4]$

Possible Answers:

$\frac{ \sqrt{10}}{3}$

$\frac{\sqrt{38}}{3}$

$\frac{ 5\sqrt2 }{3}$

$\frac{ \sqrt7}{3}$

$\frac{ \sqrt2 +5}{3}$

Correct answer:

$\frac{ \sqrt2 +5}{3}$

Explanation:

Two of the radicals can be simplified. The $\sqrt2$ term is irrational and cannot be simplified any further.

$[\sqrt2, \sqrt 9, \sqrt4] = [\sqrt2,3,2]$

Add up the numbers.

$\sqrt2+3+2 = \sqrt2 +5$

Divide this quantity by three.

The answer is: $\frac{ \sqrt2 +5}{3}$
