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° .

Nathalie has one large bowl of popcorn. She invite 3 friends over to watch a movie. Her brother takes 1/5 of the popcorn for him
OLEGan [10]

Answer:

Each friend gets  \frac{1}{5}  of the popcorns.

Step-by-step explanation:

Nathalie's brother takes 1/5 of the popcorn for himself.

so there is ( 1 - 1/5)

                 = 4/5 of the popcorns  left in the bowl

including Nathalie and her 3 friends, there are (3 + 1) = 4 persons.

So, each friend gets

\frac(4}{4 \times 5}

=\frac{1}{5}

of the popcorns

How to work this problem must show work. n-2
Leona [35]
I am only guessing that you mean:

(n-2)/-3<7  if so, multiply both sides by -3 (and reverse the direction of the inequality sign because of negative mulitplication!)

n-2>-21  add 2 to both sides

n>-19
