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:
The correct answer is B. 144
Answer:
280 ones
Step-by-step explanation:
Answer:
Product B performed worse in the study because 86% failed to get relief with this product, whereas only 78% failed to get relief with Product A
Step-by-step explanation:
We are given the following in the question:
Product A:
Number of people,
Number of people who received relief,
Proportion of people who received relief from product A =
Proportion of people who did not received relief from product A =
Product B:
Number of people,
Number of people who received relief,
Proportion of people who received relief from product B =
Proportion of people who did not received relief from product B =
Product B performed worse in the study because 86% failed to get relief with this product, whereas only 78% failed to get relief with Product A
Answer:
probably 4.5
"Step-by-step explanation:
To break even, we need the total profit to be equal to 0. If we make x dollars in 2012, then we need to solve
2.5 + 1.75 + (-3.3) + (-1.4) + x = 0
This gives us x = 0.45 in thousands.
Since the question asks us to give the answer in hundreds, we multiply by 10 and get 4.5. Thus the profit in 2012 must be 4.5 (in hundreds) to break even."
