In a sample of 16 sales calls employee A closed the contract for an average value of 1800 TL with a standard deviation of 100 TL. Company policy requires that new members of the sales team must exceed an average of 1750 per contract during the trial (probation) employment period. a) Can we conclude that employee A has met this requirement at the significance level of 95%?

b) What about if the significance level is 90%?

c) What is the conclusion in a) if the sample of calls becomes 144? The average and standard deviation remain the same at 1800 and 100 TL respectively.

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x

2 equivalent expressions to represent the area of a rectangle and the top is n-3 and the side is 2

area of the rectangle = length * width

given length = n - 3

width = 2

replace it in the area

so area of the rectangle = (n-3) *2

= 2(n-3)

one of the expression is 2(n-3)

to get another expression we distribute 2 inside the parenthesis

2(n-3) is 2n - 6

so another expression is 2n - 6

two equivalent expression are

2(n - 3)   , 2n - 6

false

ok

hope this
