Mean: add all the numbers & divide by how many numbers thee are
Median: arrange the numbers from least to greatest then mark off one from each side until you get to the middle number. That is the median
Mode: To find the mode, or modal value, it is best to put the numbers in order. Then count how many of each number. A number that appears most often is the mode.
Range: To find range, find the highest number & subtract the lowest number from it. That number is the range
Answer:
i thank is is the number 2
Answer: A
Step-by-step explanation:
Statement A is right because 2x is being added to 1 which makes it a sum statement.
Statement B is wrong because 1 is the coefficient in this expression, 2 is the coefficient of x.
Statement C is wrong because the only variable in the expression is x .
Statement D is wrong because 2x is not being multiplied by 1.
The percentages in this problem are defined as follows:
- 155 poems: 100% of 155 poems.
- 31 poems: 20% of 155 poems.
- 186 poems: 120% of 155 poems.
<h3>How to calculate the percentages?</h3>
A percentage is calculated as the division of the number of desired outcomes by the number of total outcomes, which is then multiplied by 100% to convert the proportion to a percentage.
From the tape diagram given at the end of the answer, the total number of outcomes is given as follows:
155 poems.
Hence the percentage of 155 poems is of:
155/155 x 100% = 100%.
The percentage of 31 poems is of:
31/155 x 100% = 20%.
The percentage of 186 poems is of:
186/155 x 100% = 120%.
