Hello there! So, by looking at the numbers, there are eighteen tens being compared to 21 * (5 + 5). Eighteen tens is equivalent to 180, because tens = 10, and 18 * 10 is 180. To solve 21 * (5 + 5), we first add what's in the parenthesis. 5 + 5 is 10. 21 * 10 is 210. And as we see, 180 < 210, because the one in the hundreds place is less than the two in the hundreds place. The answer is eighteen tens < 21 * (5 + 5).

Find the mean of the data summarized in the given frequency distribution. Compare the computed mean to the actual mean of 50.7 d
Svet_ta [14]

Answer: The mean of the frequency distribution is 51.7°.

The computed mean 51.7° is greater than the actual mean 50.7° .

Step-by-step explanation:

The given table :

  Low Temperature ​(°​F)      Frequency     Mid -value  

      Class interval                  f                        x                  fx

          40-44                           2                     42.5               85

          45-49                           7                     47.5               95                      

          50-54                          9                     52.5               105

           55-59                         5                     57.5                115

           60-64                          1                      62.5               25

\text{Now, Mean}=\dfrac{\sum fx}{\sum f}\\\\=\dfrac{85+332.5+472.5+287.5+62.5}{24}\\\\=\dfrac{1240}{24}=51.6666666667\approx51.7

The computed mean 51.7° is greater than the actual mean 50.7° .
