Answer:
15y - 25 = 5 (3y + -5) which makes the equation 15y - 25 = 5 (3y - 5)
Step-by-step explanation:
In order to factor with a GCF, what I like to do is divide the whole first equation by whatever the distributed number in the second equation is.
This makes 3y + -5, which is just 3y - 5.
This makes your answer known. Once you have your answer, insert it BACK into the equation to make sure it is equal. (In this case, I have checked, and it is indeed the correct answer.)
So your answer has been found at this point.
Hope this helps.
Answer:
f(x) = x+3
Step-by-step explanation:
a) For sketching the graph, we need to plot all the points on the XY plane.
Let x represents the time (in years) and y represents the height of the mountain Ash tree (in feet).
We plotted the graph through excel.
b) Using the trendline function in Ms Excel, we get the equation representing this graph
Equation is: y = 0.9783x + 3.6086
The function that models the graph will be calculated graphically that is,
f(x) = x+3
Answer:
the last two (4,2) and (10,5)
Step-by-step explanation:
Point estimate is the method of looking for an approximate value of some parameter - example: the mean (average) and it could be also the sample standard deviation of a population from random samples of the population.
To get the point estimate: 20 (people wearing hearing aids) / 304 (total random sample) = 0.0657894 or 0.066
