A random sample of 500 army recruits has a mean height
of 68 inches with a standard deviation of 2.5 inches. If a
95% confidence interval is constructed, with all the
conditions having been met, what is the margin of error?
a) 68
c) .22
b) 6.02
d).184

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation

graph of this function as shown below:

definitely a. the others have almost all data points on one side of the line.

step-by-step explanation:

false

step-by-step explanation:

the meaning of changing is to edit or make something different.

but transmitting means cause (something) to pass on from one place or person to another.

there 2 different things
