How can you know if this equation is true?

Notice how 1/2 and 3/8 are positive numbers. We add two positive numbers meaning that the result should be larger. However 2/5 = 0.4 is not larger than 1/2 = 0.5

So something went wrong with the adding. It turns out that the error is when the person added the numbers in the denominators (2 and 8 to get 10). This is not allowed. The denominators must be the same and stay the same in order for the fractions to be added.

For example: 1/7 + 2/7 = (1+2)/7 = 3/7
The 7s in the denominator do not change

Therefore the answer is choice B) Not true because 2/5 < 1/2

The median of this box and whisker plot is 73

A box and whisker plot is defined as a graphical method of displaying variation in a set of data. In most cases, a histogram analysis provides a sufficient display, but a box and whisker plot can provide additional detail while allowing multiple sets of data to be displayed in the same graph. Box and whisker plots are very effective and easy to read, as they can summarize data from multiple sources and display the results in a single graph. Box and whisker plots allow for comparison of data from different categories for easier, more effective decision-making.

From the given data, following can be inferred

  • Population size: 18
  • Median: 73
  • Minimum: 55
  • Maximum: 89
  • First quartile: 61.75
  • Third quartile: 83.5
  • Interquartile Range: 21.75

which is demonstrated in the box and whisker plot below

What type of number has a decimal that does not repeat or end?
galina1969 [7]
A number that has a decimal that does not repeat or end in an irrational number.  The decimal goes on forever, without a pattern.  Think of it as it is irrational to keep going on and on and on.   Irrational numbers also cannot be put into fractions.
-5 is an integer, it is a whole (positive or negative without a decimal/fraction) number.  An integer can be any whole number as long as it is a whole number and does not have a decimal.<span />

After an office party, 4 1/3 pizzas are left. A day later, there are 1 5/6 pizzas left. How munch pizza was eaten during the day
IceJOKER [234]

Answer:

15/6 pieces of pizza were eaten. Which is equivalent to 2.5. So 2.5 pizzas were eaten.

Step-by-step explanation:

Just did the math. Convert 4 1/3 to 0/6. So 1 times 2 is 2, and 3 times 2 is 6. Which would give you 4 2/6 which has the same denominator as 1 5/6.
