Let us take a sharp point for the graph.
In 4 hours total earning is $30.
Therefore, earnings per hours would be 30/4 = $7.5 per hour.
Are given direct variation between Total earnings(E) and Number of hours worked(h).
So, we can setup a direct variation as
Total earnings = Earning each hour * Number of hours.
Therefore, direct variation function would be
E=7.5*h.
Therefore, the direct variation function between E, the total earnings in dollars, and h, the number of hours worked is E = 7.5h.
Answer:
It's y=3x
Step-by-step explanation:
The y-intercept is 0, it's direct variation. The slope(rise/run) is 3.
Answer:
B. it makes your results more convincing
Step-by-step explanation:
A scientific experiment involves the replication and repetition of the experiment. Repetition or conducting the multiple trials of the experiment is very crucial for a scientific experiment.
The experiment is performed to understand and explain the natural phenomenon and the repetition of the experiment ensures that the results obtained from these trials are efficient either to support the hypothesis or to disprove the hypothesis.
Experimenting with multiple trials removes the chances of errors in the experiment, increases the efficiency and strengthens the results to prove or disprove the hypothesis. In other terms, it can be said that it makes the results more convincing.
Thus, Option-B is the correct answer.
We will have the following:
* If Kristin does not decrease the price of her cakes, her projected weekly revenue from cake sales will be $2500.
*If Kristin decreases the price of her cakes, her projected weekly revalue will be $2520.
*Kristin will obtain the same revenue if she sells the cakes for $24 or $21.
