Step-by-step explanation:

This is a probability related problem.

Probability is the likelihood of an event to occur;

Pr = $\frac{number of possible outcomes}{Total sample space}$

The sample space here is from 1 to 25 which is 25

Pr of a card marked 8; we have just 1 possible outcome;

Pr(8) = $\frac{1}{25}$

Pr of drawing a card that is a multiple of 5;

Multiples of 5 = 5, 10, 15 and 25

Pr (multiples of 5) = $\frac{4}{25}$

Pr of drawing a card with odd numbers:

Number of odd numbers between 1 and 25 = 13

Pr(odd numbers) = $\frac{13}{25}$

Pr of drawing a number with square number on it;

Square numbers between 1 and 25 = 1, 4, 9, 16 and 25

Pr(square numbers) = $\frac{5}{25}$ = $\frac{1}{5}$

Answer:

Step-by-step explanation:

Given the expression

$\frac{(2^3)(2)^4}{2^{10}} \\$

Using the following laws of indices;

$\frac{a^m}{a^n} = a^{m-n}\\a^m \times a^n = a^{m+n}$

The expression becomes;

Step 1: Multiplication rule

$=\frac{(2^3)(2)^4}{2^{10}} \\= \frac{2^{3+4}}{2^{10}}\\= \frac{2^7}{2^{10}}$

Using the division rule of exponent (Quotient of powers);

$= \frac{2^7}{2^{10}} \\= 2^{7-10}\\= 2^{-3}\\also \ a^{-m} = \frac{1}{a^m}\\ 2^{-3}= \frac{1}{2^3}\\\frac{1}{2^3} = \frac{1}{8}$

Hence the result of the expression is 1/8

almond37 [142]

The answer is 670.
this is because 96 plus 287 is 383.
so he sold 287 on the 1st day, and 383 on the second day.
383 plus 287 equals 670.
