Answer: 18
Step-by-step explanation:
- The<u> sample mean</u> is the best point estimate of the population mean .
Given : A simple random sample of 5 observations from a population containing 400 elements was taken, and the following values were obtained (12 18 19 20 21).
Then , the sample mean = 
sample mean 
Hence, A point estimate of the mean is 18.
Answer:
9,40 is the answer of your question
Answer:
f(4) = -10
x = 0
Step-by-step explanation:
From the graph attached,
For x = 4,
Value of the function will be,
f(4) = y value at x = 4
f(4) = -10
Similarly, for y = g(x) = 2,
x value of the function will be,
x = 0
For which g(0) = 2
Therefore, for x = 0 value of the function will be 2.
g(0) = 2
Answer:
y=-2x+12
Step-by-step explanation:
This is an equation in slope-intercept form:
y=mx+b (where m is the slope and b is the y-intercept)
We are given the slope, -2.
y=-2x+b
We plug in the values (5,2):
2=(-2)*5+b
2=-10+b
b=12
The equation is:
y=-2x+12
Answer:
the equation in letter D is a linear function.
