B
Step-by-step explanation:
0.20 represents the cost per ounce
“Z” represent the number of additional ounces
0.46 is the fee that is added on for the first ounce when mailing the letter

Use properties of logarithm to expand the logarithmic expression as much as possible. Where possible, evaluate logarithmic expressions without using calculator.
log4(4/x) = log4(4) - log4(x) = 1 - log4(x)
------------------------------------------------------
Evaluate the expression without using a calculator.
log7 1/root:7
log7(1/sqrt(7))
= log7(1) - log7(sqrt(7))
= 0 -(1/2)log7(7)
= 0-1/2
= -1/2</span>
Because of the vertical angles theorem, BAC becomes 50°. And angle B is 180-(50+30)=100.
If all 3 triangles are similar, the angles of triangle EFG are 30°, 50°, 100°
The relative frequency with which the coin will land on tails 12 of those times willl be 48%. None of the given options are correct.
<h3>What is the formula for calculating the joint relative frequency?</h3>
Assume you need to compute the joint relative frequency of a certain category inside a larger category. Then there's the proportion of that specific category's frequency to the total frequency of that large category.
If the experiment is run 25 times and we receive tails 12 times, the relative frequency of receiving tails is as follows:
![\rm R = \frac{12}{25} \times 100 \\\\ R = 48 \%](https://tex.z-dn.net/?f=%5Crm%20R%20%3D%20%5Cfrac%7B12%7D%7B25%7D%20%5Ctimes%20100%20%5C%5C%5C%5C%20R%20%3D%2048%20%5C%25)
Hence, the relative frequency for the given condition will be 48%.
