Don't try and do this all at once. Break it down, otherwise you'll have layers and brackets all over the place.
Step One
Find 23/0.3
X = 23/0.3 = 76.7
Step Two
Now Divide by 20
x1 = 76.7 / 20
x1 = 3.83
Step Three
Take this result and put it over 24
x2 = x1/24
x2 = 3.83 / 24
x2 = 0.1597 <<<< Answer
Total cost
17.95 + 27.50 + 94.20 + 12.30 + 12.30 = 164.25
tax
164.25 * 5% = 8.21
164.25 * 1.5% = 2.47
164.25 * 2% = 3.28
sum of the tax
8.21 + 2.47 +3.28 =
13.96
your answer is C
The kind of probability is being used when one calculates the probability that a randomly selected adult who works from home and has a bachelor's degree or higher is <em>relative frequency.</em> This probability is based on actual measurements, like a survey. Using this method will enable us to calculate for the probability of each variable occurring, or a combination of two or more variables with respect to the number of trials in the sample.
T = 4.2m + 2.4
T is the total gallons
M is the minutes
Answer:
y = 18·8^x
Step-by-step explanation:
We assume you want a model that looks like y = ab^x.
To find the values of "a" and "b", you can fill in the given numbers and solve the system of equations:
18 = a·b^0
9216 = a·b^3
The first equation tells you ...
18 = a
Dividing the second equation by the first gives ...
9216/18 = (a·b^3)/(a·b^0) = b^3
512^(1/3) = b = 8
The exponential function is ...
y = 18·8^x
