For each of the following statements, identify the number that appears in boldface type as the value of either a population char
Alex Ar [27]

Answer:

a) 88% is a population characteristic.

Step-by-step explanation:

A population characteristic, also known as population parameter, describes a characteristic about the entire population of variables (usually numerically). Basically, it is a description (usually numerical) about a group of variables, obtained from the total population of such a variable.

WHILE

A statistic describes that same characteristic, only that it is obtained from a sample of variables taken from the population.

For the question above, a department notices that 88% of ALL their customers who use the store's credit plan pay their bills on time. It is evident that this is a population charasteristic, as it is obtained from examining the entire population of customers.

Hope this Helps!!!

Please explain as well, solve the trigonometric equation
aliina [53]

Given:

The trigonometric equation is:

\tan x\sin x=\tan x\cos x

To find:

The solutions for the given equation over 0^\circ.

Solution:

We have,

\tan x\sin x=\tan x\cos x

It can be written as

\tan x\sin x-\tan x\cos x=0

\tan x(\sin x-\cos x)=0

\tan x=0 and (\sin x-\cos x)=0

The solutions over 0^\circ are:

x=90^\circ,180^\circ and \sin x=\cos x

x=90^\circ,180^\circ and x=45^\circ, 225^\circ

Therefore, the correct option is D.
