7 0

Answer:

-7x^3+39x^2+136x

Step-by-step explanation:

= x(x-8) (-7x - 17)

( x - 8 ) ( -7 x - 17) : -7x^2 + 39x+136

= x( -7x^2 + 39x + 136)

= x( -7x^2) + x * 39x * 136

= -7x^3 + 39x^2 + 136x

Carpetland salespersons average $8,000 per week in sales. Steve Contois, the firm’s vice president, proposes a compensation plan
olya-2409 [2.1K]

Answer with Step-by-step explanation:

Since we have given that

Average per week in sales = $8000

Steve hopes that the results of a trial selling period will enable him to conclude that the compensation plan increase the average sales per salesperson

So, the appropriate null and alternate hypothesis would be

H_0:\mu=8000\\\\H_a:\mu>8000

b. What is the Type I error in this situation? What are the consequences of making this error?

Type 1 error are those errors in which null hypothesis are supposed to be rejected, but it does not get rejected.

It means sales per week is greater than $8000 but in actual it is not.

c. What is the Type II error in this situation? What are the consequences of making this error?

Type 2 are error are those errors in which null hypothesis are supposed to be accepted but it get rejected.

It means average sales per week is actually $8000 but it is calculated that average sales is less than $8000.

A baseball player made six hits in nine innings. What is the ratio of hits to innings?
UNO [17]
A baseball player made six hits in nine innings.

Therefore, his ratio of hits to innings, which means his number of hits relative to the number of innings, is 6:9.

However, this isn't simplified.  To simplify a ratio, we must find the GCF (Greatest Common Factor) of the two terms.

The GCF of 6 and 9 is 3, thus, we divide both of the terms by 3 to get our simplified answer.

6:9 = 6/3 : 9/3 = 2:3

Your answer is that the ratio of hits to innings for the baseball player is 2:3.  (This can also be expressed as 2/3 or 2 to 3.)

Hope this helps! :)
