Answer:
B. you need atleast one variable for an algebraic expression.
an equals sign would make it an algebraic equation,
just a coefficient and a variable is the most basic algebraic expression. you don't need anything other than those for an expression. you can have more than one number, and more than one operation, but they don't have to be there.

78.3/3.48= 22.5
quotient is the result of division. simply divide 78.3 by 3.48 in a calculator and you get your answer.
So lets do it like this:
z = (X-Mean)/SD
<span>z1 = (8-12)/2 = - 2 </span>
<span>z2 = (16-12)/2 = + 2 </span>
<span>According to the Empirical Rule 68-95-99.7 </span>
<span>Mean more or less 2SD covers 95% of the values </span>
So t<span>he percentage of data points falling between 8 and 16 = 95%
</span>I hope this can help
$78.17 rounds to $78
15% of $78 = $11.70 which rounds to $12
By adding 3 then subtracting 2, you're pretty much just adding 1.
Starting from 7;
7, 8, 9, 10, 11, 12, etc.
I hope that helps!
