A salesperson set a goal to earn $2,800 in October. He receives a base salary of $1,400 per month as well as a 8% commission for

skad [1K]

Answer:

$\$17,500$

Step-by-step explanation:

Let

x----> that month's sales

y----> October earnings

we know that

$8\%=8/100=0.08$

$y=0.08x+1,400$ -----> equation A

$y=2,800$ -----> equation B

Equate equation A and equation B and solve for x

$2,800=0.08x+1,400$

$0.08x=2,800-1,400$

$x=1,400/0.08$

$x=\$17,500$

NEED URGENT HELP I WILL DO ANYTHING

seropon [69]

1. Here are the four steps of the statistical process in correct order:
1) Plan - Form a question that can be answered by data.
2) Collect data - Design and implement a plan that collects data.
3) Process - Analyze the data using graphical and numerical methods.
4) Present and discuss - Interpret and compare the data.
So your answer is the last option.

2. I am definitely sure that Edgar wrote a statistical, because every neighbor can give a different answer. A statistical question is the question which you don't expect to get only one answer. Instead of that you will get a variety of different answers.

3. According to what I've mentioned before, the only statement which shows a characteristic of a statistical question is: There can be variability in the answers to the question.

4. I am completely sure that this one is statistical question: How many hours do you spend each week training for a sports league? Because it could be answered with variability.

5. The only statistical question in his survey is: How many hours do you spend at the food court each month?. Because it gives him more different answers for his survey.

tan ( - pie / 12 ) =

- tan ( pie / 12 ) =

_________________________________

Remainder formula :

tan^2 (x) = [ 1 - 2Cos(2x) ] ÷ [ 1 + 2Cos(2x) ]

_________________________________

Thus :

tan^2 ( pie/12) =

[ 1 - Cos( 2pie/12 ) ] ÷ [ 1 + Cos( 2pie/12 ) ] =

[ 1 - Cos( pie/6 ) ] ÷ [ 1 + Cos( pie/6 ) ] =

[ 1 - √3/2 ] ÷ [ 1 + √3/2 ] =

[ 2 - √3 / 2 ] ÷ [ 2 + √3 / 2 ] =

[ 2 - √3 ] ÷ [ 2 + √3 ] =

2 - √3 / 2 + √3 =

(2 - √3)(2 - √3) / (2 + √3)(2 - √3) =

(2 - √3)^2 / 4 - 3 =

(2 - √3)^2 / 1 =

(2 - √3)^2

So :

tan^2 ( pie/12 ) = (2 - √3)^2

Take a square root from both sides

tan( pie/12 ) = 2 - √3

_________________________________

Thus ;

- tan ( pie/12 ) = - ( 2 - √3 )

- tan ( pie/12 ) = - 2 + √3

Approximately :

- tan ( pie/12 ) = - 2 + 1.732

- tan ( pie/12 ) = - 0.268

The height and sides of a triangle are four consecutive integers. the height is the first integer, and the base is the third int

Maru [420]

Answer:

84 in²

Step-by-step explanation:

The side lengths of the triangle are 3 consecutive integers whose sum (the perimeter) is 42. The average of those integers, 42/3 = 14, is the middle of the three, so they are 13, 14, 15. We're told the perimeter is in inches, so all of these dimensions are inches.

These are the last three of 4 consecutive integers, so the first, the height of the triangle, is 12. The base of the triangle is the 3rd of the four integers, so is 14. Then the area is ...

A = (1/2)bh = (1/2)(14)(12) = 84 . . . . . square inches.
