Answer:
x = -10
Step-by-step explanation
5x+7(-3x-14)=162
First, 5x -21x - 98 = 162
Then, combine like-terms, -26x - 98 = 162
After that, add 98 to 162, and you'll end up with 260.
Finally, you'll wanna divide the -26x to the 162.
You'll end up with x = -10
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 and the alternative hypothesis as
As they are two mutually exclusive statements then if
: <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
: <em>"The true average weight of geese is less than or equal to 40 pounds"</em>
I believe the answer is 4.4
The correct answer would be, Jeremy rides at a greater speed than Kevin.
Step-by-step explanation:
Jeremy rides at a rate of 15 miles per hour
Kevin rides at a rate given in the table
Let Y be the distance traveled by Jeremy
And X be the number of hours
Then for Jeremy:
y/x = 15/1
=> y= 15 x
For Kevin:
(46-23)/(4-2)
= 23/2
= 11.5
So for Kevin, Y = 11.5 x
So when Jeremy's and Kevin's rates are compared,
15 > 11.5
which means Jeremy rides at a greater speed.

0.27 is a multiplicative inverse because the product of and is 1
A multiplicative inverse is a number in the form 1/x which gives 1 as the result when multiplied by x. It can also be referred to as the reciprocal
That is:
Express 0.27 as a fraction
If
Multiply x by 1/x
Since , then 0.27 is a multiplicative inverse
