You would have no problem at all if it said "7 cows minus 2 cows", or "7 books minus 2 books". The THINGS just happen to be m's instead of cows or books.

Answer:

E) 6

Step-by-step explanation:

a/b = 6

36/b = 6

6b = 36

b = 36/6 = 6

b/x = 36

6/x = 36

36x = 6

x = 6/36 = 1/6

hence 1/x = 6

<u>Answer:</u>

• mean = 61

• mode = 50

• median = 57.5

<u>Step-by-step explanation:</u>

• The mean is calculated by adding all the values together, and dividing the result by the number of values.

∴ mean =  \frac{60 + 50 + 50 + 70 + 40 + 80 + 65 + 55 + 50 + 90}{10}

⇒ mean = \frac{610}{10}

⇒ mean = 61

• The mode of a set of values is the value that is the most common (has highest frequency) among them.

50 is the most common value.

∴ mode = 50

• The median is the middle-value of a set of ordered values.

∴ We have to first rearrange the set:

⇒  40, 50, 50, 50, 55, 60, 65, 70, 80, 90

Now we need to find the middlemost value:

Since we have 10 values, which is an even number, we have to use the formula:

median = \frac{(n/2)^{th} \space\ term  \space\ + \space\ [(n/2) + 1]^{th} \space\ term  }{2}

where n is the number of values.

∴ median =  \frac{(10/2)^{th} \space\ term  \space\ + \space\ [(10/2) + 1]^{th} \space\ term  }{2}

⇒ median =  \frac{5^{th} \space\ term  \space\ + \space\ 6^{th} \space\ term  }{2}

The 5th and 6th terms in our ordered series are 55 and 60 respectively.

∴ median = \frac{55 + 60}{2}

⇒ median = 57.5
