Here's the info for f(x): We are going to find the slope of the line and then write the equation for the line using one of the given points. The coordinate points we are given are (0, 0) and (2, 4). Using the slope formula:

gives us a slope equation of:

and the slope is 2. Using the point (0, 0) to write the equation of the line for f(x) looks like this in the slope-intercept form of the equation:

where m is the sloppe of 2 that we found and

and

are the coordinates of one of the points. It doesn't matter which one you choose; you will get the same answer whether you use (0, 0) or (2, 4): y-0=2(x-0) Distributing that 2 into the parenthesis and simplifying gives you the equation of y = 2x, or in our function notation, f(x) = 2x. Since f(x) is the first part of g(x), so far for g(x) we have that g(x) = 2x + k. Now we will do the same thing for g(x) that we did for f(x) as far as writing its equation down; we don't need to find the slope cuz the slope of g(x) is the function f(x). The equation for g(x), using the point (0, 2) (again, you could have used either point; I just picked (0, 2) cuz the other one has a decimal in it!): y - 2 = 2(x - 0). Distributing that 2 into the parenthesis gives you this: y - 2 = 2x - 0; y = 2x + 2. So 2 is your k value!

SA = LH + LW + WH + 2(1/2LH)
SA = 4*2 + 5*2 + 3*2 + 2*1/2*4*3
SA = 8 + 10 + 6 + 12
SA = 36
Answer:
26
Step-by-step explanation:
8 + 3n
n = 6
8+3(6)
= 8 + 16
= 26
Answer: It is called a sample statistic.
Step-by-step explanation:
Since we have given that
A researcher records the time it takes to complete a memory task in a sample of 25 participants. He finds that the average participant completed the test in 43 s.
The average time to complete this task is called sample statistic.
As we know that
Sample statistic is the quantity which we get from the sample taken from a any specified population for using this quantity to calculate the same.
In our case, average participant completed the test = 43 sec.
It is sample statistic as we will use to find the average time for the population i.e. 25 participant to get the same calculation i.e. average time.
We will get average time is also equal to 43 sec.
Hence, it is called a sample statistic.
