Answer:
y = 4
Step-by-step explanation:
because 5 x 4 = 20 and 20 × 4 = 80 and so on y is equal to four
Answer:
For this case we want to test if life expectancy in country 1 is more than 10 years lower than in country 2, (alternatibe hypothesis), so then the system of hypothesis are:
Null hypothesis: 
Alternative hypothesis:
Or equivalently:
Null hypothesis: 
Alternative hypothesis:
Step-by-step explanation:
Previous concepts
A hypothesis is defined as "a speculation or theory based on insufficient evidence that lends itself to further testing and experimentation. With further testing, a hypothesis can usually be proven true or false".
The null hypothesis is defined as "a hypothesis that says there is no statistical significance between the two variables in the hypothesis. It is the hypothesis that the researcher is trying to disprove".
The alternative hypothesis is "just the inverse, or opposite, of the null hypothesis. It is the hypothesis that researcher is trying to prove".
Solution to the problem

Well, I'm not sure what units "0.5" apply to, but to find the distance he rode, you will need to multiply.
0.5 * 24 = 12.
Barry rode his scooter for a distance of 12 [insert units here].
Hope this helps! Have a great day :)
Extraneous solutions are the values that we get when solving equations which aren't really solutions to the equation.
<h3>
What are extraneous solutions?</h3>
Your information is incomplete. Therefore, an overview will be given. An extraneous solution is the root of a transformed equation which is not a root of the original equation since it was excluded from the domain of the original equation.
The reason extraneous solutions exist is simply that some operations produce extra answers, and these operations are a part of the path to solving the problem.

Answer:
6
Step-by-step Explanation:
To simplify
, we will look for numbers that 504 can be divided by until there are no perfect square roots under the radical.
[] To do this, we can think of perfect square roots such as 4, 9, 16, etc
We can divide 504 by 36 for an answer of 14, so
can be written as
which can be written as 6
because the square root of 36 is 6.
Have a nice day!
