The thing when interpreting the problem is that we didn't know what value we will going to insert but then the interpretation of the means is If we sampled all days, the arithmetic average or expected number of tickets written would be 6.5 tickets per day.
We want our exponential function to look like
y = ab^x.
Let a = the initial y-value.
Our initial value is the first number given for f(x). So, a = 3.
Let b = the number that is needed to go from 3 to 6 to 12 to 24 to 48.
We find b by division.
So, b = the next number divided by the previous.
So, b = 6/3 = 2.
We now plug in our values into the general formula above.
y = ab^x
Answer: y = (3)(2)^x
The 7 before the decimal would be classified as a tenth
Answer:
15 grams
Step-by-step explanation:
If the copper made up 80% of the weight of the bar (w), then the bar weighed ...
0.80w = 12 g
w = (12 g)/0.80 = 15 g
_____
Copper has a density of about 8.96 g/cm³, so Nancy's "large" metal bar is about the size of two sugar cubes.
Answer:
12/13
Step-by-step explanation:
The cosine of an angle in a triangle can be calculated as a relation between the adjacent side and the hypothenuse. So, in this case the adjacent side of θ is 24 and the hypothenuse is 26.
Then:
cos(θ) = 24/26 = 12/13
