percent- 40%
decimal- 0.4
percent- 2/5
Step-by-step explanation:
you divide 30 by 12 because he practices piano 12/30 days of the month
We have to determine if the functions are linear or not.
We can do this by rearranging the equations in this form:
where m and b are constants.
<em>NOTE: There are many ways to prove that a function is linear, but this is the easiest for this question. </em>
36.
As this function can not be written in the form y=mx+b, then it is not linear.
37.
This function is now in the form y=mx+b, where m=3/4 and b=-15. Then, this function is a linear function.
Answer:
36. Non-linear.
37. Linear.

Answer:
The correct option is d) convenience sample
Step-by-step explanation:
In statistics, we use different sampling techniques to gather a chunk of sample data from a very large population.
There are many sampling techniques and out of them one is convenience sampling.
Convenience Sampling:
The convenience sampling is defined as the sample data which is readily and conveniently available.
Examples:
1. Asking people questions at a place that is convenient for you.
2. Asking your friends or family members
3. A college student asking for student's opinion at the college who is surveying for his thesis.
In the given scenario, Kristen Ashford has list of 5,000 subscribers for Wind Surfing magazine. She chooses the first 100 of the 5,000 names, this is clearly a convenient sample since the sample is easily, readily and conveniently available.
If she had selected 100 names randomly then it would have been called random sampling but in this case, she simply selected the first 100 names for the sake of convenience therefore, it is a convenience sample.
Answer:
we will need 7 bags
Step-by-step explanation:
To solve this problem we first have to calculate the total area of the garden
a = area
b = base = 8m
h = height = 12.5m
a = b * h
we replace with the known values
a = 8m * 12.5m
a = 100m²
Now that we know the total area of the garden and the area occupied by a single bag, we divide the total area by what a bag covers.
100m² / 16m² = 6.25 bags
because we cannot buy a fraction of a bag we will need 7 bags
