Ede4ka [16]

I’m assuming you meant in each shelf there is 14 movies, and there is 4 shelves, so you would multiply 14 x 4 which would be 56 movies

The distribution of individual incomes in the United States is strongly skewed to the right. In 2013, the mean and median income

vesna_86 [32]

Answer:

The mean would be $322,343 and the median would be $196,723.

Step-by-step explanation:

Since the distribution of individual incomes is skewed to the right, it means that the distribution has a long right tail.

Drawing a distribution with this characteristic, we can see how the majority of the data falls into the left side of the graphic, meaning that a lot of people receive less income. Following this reasoning, the mean which is the amount of the data (in this case individual income) divided by the amount of people, would be the higher number, meaning that the few people who earn more money would influence in making this number higher.

Following this reasoning, the median (which is not influenced by this difference) would be the less high number.

3 3/8 divided by 3/4 using cross multiplication algorithm

Bogdan [553]

Answer

3 3/8 ÷ (3/4) = (9/2) = 4 ½

Explanation

We are asked to evaluate 3 3/8 divided by 3/4 using cross multiplication algorithm.

The algorithm will need us to put the mixed fraction in definite fraction form (improper fraction) and to evaluate the division, we change the division sign into multiplication sign and the fraction after the division sign changes into its reciprocal.

3 3/8 = (27/8)

(3 3/8) ÷ (3/4)

= (27/8) ÷ (3/4)

$\begin{gathered} \frac{27}{8}\div\frac{3}{4} \\ =\frac{27}{8}\times\frac{4}{3} \\ =\frac{108}{24} \\ \text{Divide numerator and denominator by 12} \\ \frac{108}{24}=\frac{9}{2} \end{gathered}$

Hope this Helps!!!
