Step-by-step explanation:
<u>Graphs</u>
The graph shows the amount of water in gallons as a function of time in seconds.
We are required to find the amount of water in the bucked after 1 second. Since the graph does not show an exact location for t=1, we must find the equation of the line.
Two points are clear on the graph: (0,0) (12,5). This gives us the necessary information to find the equation of the line, which has the form:

Where w is the amount of water in the bucket, t is the time, and m and b are two constants to be determined.
Using the point (0,0):

It follows that b=0
The equation now takes the form:

Using the point (12,5):

We find m:

The final equation is:

Substituting t=1:

The bucket has 5/12 gallons of water at t=1 second. Expressing the answer as an ordered pair:

Answer:
B. stratified.
Step-by-step explanation:
If a population is composed by identifiable groups or strata, with large variations between groups, the stratified sampling should be applied in order to comprehend and represent all of the different groups in the sampling process.
Therefore, the answer is alternative B. stratified.
Answer: 36.65 inches
Step-by-step explanation:
The length of arc with a central angle x and radius r in a circle is given by :-

Given : Radius of a circle = 60 inches
Central angle =
Now, the of length of arc is given by :-

Hence, the length of arc = 36.65 inches.
12x is equal to (13-9)3x, so put a tick there.
15x is equal to 6x/2 * 5
24 x is equal to the middle row, which simplifies to (12)2x = 24x.
