Step-by-step explanation:

In the case of a discrete probability distribution of a random variable X, the mean is equal to the sum over every possible value weighted by the probability of that value; that is, it is computed by taking the product of each possible value x of X and its probability p(x), and then adding all these products together

When Spencer was 5, he was 28 inches tall. Today he is 5 feet 3 inches tall. What is the percent increase in Spencer’s height?
Flura [38]

Answer:

The percentage increase in Spencer’s height is 125 %

Solution:

\begin{array}{l}{\text { Percentage increase }=\frac{\text { change in height }}{\text { initial height }} \times 100 \%} \\\\ {\text { percentage increase }=\frac{\text { increased height - initial height }}{\text { initial height }} \times 100 \%}\end{array}

Initial height of spencer = 28 inches  

Increased height of spencer = 5 feet 3 inches  

= 5 feet + 3 inches  

(5 feet = 5 ×12=60 inches)

= 60  + 3

 \begin{array}{l}{\text { Increased height }=63 \text { inches }} \\ {\text { Percentage increase }=\frac{63-28}{28} \times 100 \%} \\\\ {=\frac{35}{28} \times 100 \%} \\\\ {=1.25 \times 100 \%} \\ {\text { percentage increase in height of spencer }=125 \%}\end{array}

1.64 as a mixed number in simplest form
garri49 [273]
By taking a look at 1.64, you can already tell the 1 will be the whole number in the fraction. So let's focus on .64. 0.64 is in the hundredths place value, so the denominator will be 100. The unsimplified fraction would be 1 64/100. To put this in simplest form we must divide 64 and 100. Let's start off with 2. 64/2 = 32 100/2 = 50 Let's continue until we can not divide by 2 anymore. 32/2=16 50/2 = 25 We can no longer divide by 2, howver there is not other number we can divide by both 16 and 25 evenly. The answer in simplest form is 1 16/25
