Converting observations from original values to standard deviation units is known as standardizing the data values. This is done in order to get values in such a form where we can compare them. For example, if we have the test scores of two different school and we want to compare the result of the students we have to first convert them into standard deviation units.
Converting the values to standard deviation units is also known as converting the values to z scores.
The formula for the z score is:
[tex]z= \frac{x-u}{s} [/tex]
where x is the data value, which is to be standardized.
u is the average of the entire data.
s is the standard deviation of the data.
Answer:
The diver’s depth is 18.5 feet below from sea level.
Given that, A diver begins at sea level and dives down 200 feet.
He ascends at a steady rate of 121/3 feet per minute for 4.5 minutes.
This depth is represented by the numerical expression is,
Negative sign indicate that below the sea level.
Hence, The diver’s depth is 18.5 feet below from sea level.
Depends on what equation it is
Because the two triangles are similar, one is a scaled down version of the other.
You can figure out that scale by comparing two matching sides, in this case AD and AB.
AD = 2 and AB = 2+4 = 6
So 2/6 = 1/3, telling us each side of the smaller triangle is 1/3 the size of the original.
Now we need to find ED and know CB = 12. Knowing ED = 1/3 of CB:
ED = 1/3 • 12 = 4
Answer:
The answer is
<h2>10 units</h2>
Step-by-step explanation:
The distance between two points can be found by using the formula
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
A (-7,-6) and B (1,0)
The distance between them is
We have the final answer as
<h3>10 units</h3>
