Rewrite 8x - 7 as the product of two factors
kykrilka [37]

Answer:

factors are any group of number or expressions which, when multiplied, produce another number or expression.

Basic example:  4 can be broken into 2 factors---2 and 2.  2 times 2 = 4

Example using an unknown:

2X + 6 = 2 * (X + 3)

In the given problem, there is no whole-number common factor.  A normal convention would be to factor based on the unknown term----thus 8X is factored into 8 and X.

So:  8X + 7 = 8 ( X + 7/8 )

The following would also be correct:

8X + 7 = 4 ( 2X + 7/4 )

If the null hypothesis of an experiment is “The true mean weight of the geese is greater than 40 pounds” what is the alternate h
Naddika [18.5K]

Answer:

<em>The true average weight of geese is less than or equal to 40 pounds</em>

Step-by-step explanation:

The null hypothesis and the alternative hypothesis are two mutually exclusive statements or hypotheses that are made about a population. The purpose is to find out if, through a study of the data, sufficient evidence is obtained to reject one and accept another

The null hypothesis is denoted as H_0 and the alternative hypothesis as H_1

As they are two mutually exclusive statements then if

H_0: <em>"The true average weight of the geese is greater than 40 pounds"</em>

the alternative hypothesis must be the opposite of the null hypothesis

H_1: <em>"The true average weight of geese is less than or equal to 40 pounds"</em>
