Answer:
To find the area of a rhombus, multiply the lengths of the two diagonals and divide by 2 (same as multiplying by 1/2): The sides and angles of a rhombus: The sides of a rhombus are all congruent (the same length.) Opposite angles of a rhombus are congruent (the same size and measure.)
Step-by-step explanation:
Hey there! I don't see a number set here, so instead I will do my best to explain what each is and how to find it.
Mean - This is the average of all of the numbers. To find the mean, add up all of the numbers. Then, divide that sum by the number of values you added up.
Median - This is the middle number in your set of data. It is not influenced by outliers, like the mean. Repeat values do count, and you have to use all of your data values, including those repeats, to find an accurate median. To find the median, put all your data values in order from smallest to largest. Begin by crossing out one number on each side (2 total each time) until you get to a middle one or two numbers. If you have one number remaining, then that is your median. If you have two numbers remaining, add those numbers together and divide by 2.
Mode - This is the number, or numbers, that appear the most. For example, if the number 4 appears 10 times in a data set, but the number 2 appears only 4 times, then number 4 is the mode (if the data set is made up of only 4's and 2's). To find the mode, look for the number that appears more often than the rest. Count up the number of times each number occurs and find the one with the highest number of occurrences. That is your mode.
Range - This is the span of your data set. To find the range, subtract the smallest number in your data set from the largest number in your data set. It should look like this: maximum - minimum = range.
Hope this helps!! :)
$30 is 60% of $50.
100 % is the whole figure. Based on the problem, 100 % is separated into two parts, 60% and 40%
100% = 60% + 40%
To get the number where $30 is 60%. Let X be the 100% number.
First, divide all number by 100% to remove the percentage and get the whole number.
100%X = 30 + 40%X
X = 30 + 0.40X
X - 0.40X = 30
0.60X = 30
To get X, divide both sides by 0.60
X = 30 / 0.60
X = 50
To check: Substitute all X by 50.
X = 30 + 0.40X
50 = 30 + (0.40*50)
50 = 30 + 20
50 = 50 EQUAL. CORRECT.
