Step-by-step explanation:
Answer: 9 feet below or -9 feet
Step-by-step explanation:
Let us say 0 is the surface of a pond. The turtle started at -2 and then traveled -7 more. We will add these negative values to each other.
-2 + -7 = -2 - 7 = -9
The turtle is now -9, or 9 feet below, the surface of the pond.

From the question
We are given the points
Finding the slopre, m
Slope is calculated using
From the given points
Therefore,
Therefore, m = -8/3
The next thing is to find
A slope parallel to m
For parallel lines, slopes are equal
Therefore,
Next, we are to find
A slope perpendicular to m
For perpendicular lines, the product of the slopes = -1
Therefore
Hence,
Therefore,
Next, we are to find the distance KP
Using the formula
This gives
Therefore,
Next, equation of the line
The equation can be calculated using
By inserting values we have
Therefore the equation is
Answer:
For this case we want to test if there is a higher incidence of smoking among women than among men in a neighborhood (alternative hypothesis). And we define p1 for men and p2 for women, so for this case the best system of hypothesis are:
Null hypothesis:
Alternative hypothesis:
And the best option would be:
a) h0: p1-p2 ≥ 0 h1: p1-p2 < 0
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
