Choose the missing exponent to create a polynomial?

1 answer:

5 0

3.

The answers 2 and 4 are incorrect because inserting that ad the missing exponent would create only a trinomial.

-9 is incorrect as it would create something more than a polynomial. 7 is incorrect as, if doing a certain type of division, would result in a larger polynomial.

Hope this helps!

Answer:

$H_{0}: \mu= 185$ and $H_{a}: \mu > 185$

Step-by-step explanation:

The null hypothesis $H_{0}$ states that a population parameter (such as the mean, the standard deviation, and so on) is equal to a hypothesized value. We can write the null hypothesis in the form $H_{0}: parameter = value$

In this context, the investigator's null hypothesis should be that the average total weight is no different than the reported value by the FAA. We can write it in this form $H_{0}: \mu= 185$ .

The alternative hypothesis $H_{a}$ states that a population parameter is smaller, greater, or different than the hypothesized value in the null hypothesis. We can write the alternative hypothesis in one of three forms

$H_{a}: parameter > value\\H_{a}: parameter < value\\H_{a}: parameter \neq value$

The investigator wants to know if the average weight of passengers flying on small planes exceeds the FAA guideline of the average total weight of 185 pounds. He should use $H_{a}: \mu > 185$ as his alternative hypothesis.

Standard form. (x+8)(x−6)

vovikov84 [41]

Answer:

x² + 2x - 48

Step-by-step explanation:

( x + 8 ) ( x - 6 )

= x ( x - 6 ) + 8 ( x - 6 )

= x*x - 6*x + 8*x + 8*( - 6 )

= x² - 6x + 8x - 48

= x² + 2x - 48

1/4 is equal to 2/8.

2/8+1/8=3/8

Carla used 3/8 of the ribbon in all. So, 5/8 of the ribbon is left.

I hope this helps :)
