Step 1
a)

7.456 \times 8 =

\begin{matrix} 7.456 \\ \times 8 \\ 59.648 \end{matrix}

∴ 7.456 \times 8 = 59.648

Step 2
b)

56 \times 35 = 1960

\begin{matrix} 56 \\ \times 35 \\ 280 \\ 168 \\ 1960 \end{matrix}

Step 1
a) $7.456 \times 8$
Factor:
$\frac{233 \times 2^{5}}{5^{3}}$
$= 59 \frac{81}{125}$
$= 59.648$ Step 2
b) $56 \times 35$
First line up the numbers vertically and match the places from the right like this.
$\begin{matrix} 56 \\ \times 35 \end{matrix}$
Now multiply the first number with the $1^{s t}$ digit in $2^{n d}$ number to get intermediate results. That is Multiply 56 with 5. Write the result 280 at the end leaving 0 spaces to the right like this.
$\begin{matrix} 56 \\ \times 35 \\ 280 \end{matrix}$
Now multiply the first number with the $2^{n d}$ digit in $2 n^{n d}$ number to get intermediate results. That is Multiply 56 with 3. Write the result 168 at the end leaving 1 spaces to the right like this.
$\begin{matrix} 56 \\ \times 35 \\ 280 \\ 168 \end{matrix}$
Now add the intermediate results to get final answer.
$\begin{matrix} 56 \\ \times 35 \\ 280 \\ 168 \\ 1960 \end{matrix}$

According to a study by Dr. John McDougall of his live-in weight loss program at St. Helena Hospital, the people who follow his program lose between 6 and 15 pounds a month until they approach trim body weight. Let's suppose that the weight loss is uniformly distributed. We are interested in the weight loss of a randomly selected individual following the program for one month. Give the distribution of X. Enter an exact number as an integer, fraction, or decimal. $f (x) =_{}$ where $\leq X \leq . μ = σ =$ . Find the probability that the individual lost more than 8 pounds in a month.Suppose it is known that the individual lost more than 9 pounds in a month. Find the probability that he lost less than 13 pounds in the month.
