5 0

Answer:

A. 0.020

Step-by-step explanation:

we calculate the standard error of the sample mean with the formula,

E=\frac{s}{\sqrt{n} },

with E= standard error of the sample mean

s= standard deviation

n= sample

So,

s= 0.2

n= 100

E=\frac{0.2}{\sqrt{100} } =\frac{0.2}{10}=0.02

Given the following linear function sketch the graph of the function and find the domain and range.
lisov135 [29]

Answer:

Domain of the given function is all real numbers and the range of the function all real numbers.

Step-by-step explanation:

The given function is

f(x)=-5x+4           .... (1)

The slope intercept form of a line function is

y=mx+b              .... (2)

Where, m is slope and b is y-intercept.

From (1) and (2), we get

m=-5,b=4

It means the slope of the line is -5 and y-intercept is 4.

Draw a line with slope -5 and y-intercept 4 on a coordinate plane as show below.

Domain is the set of inputs and range is the set of outputs.

The function is defined for all values of x. So, the domain of the function is all real numbers.

Domain=\{x|x\in R\}

The value of function can be any real number. So, the range of the function is all real numbers.

Range=\{y|y\in R\}

Therefore, the domain of the given function is all real numbers and the range of the function all real numbers.

What is the slope of the line y=1/6x+3/2
const2013 [10]

Answer:

1/6

Step-by-step explanation:

When the y is isolated on one side and is not multiplied by anything (other than one), the slope is the value before the x. In this case, it's 1/6. And in if y is perfectly isolated, then the y-intercept is the value after the x, which is positive 3/2 in this case.
