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 answer would be f: y=-x^3 -4
Elaboration:
You don't show if there's a 4th answer so I'm just assuming you have one, but if there is no option, then I apologize.
Explanation:
y = -x^3 flips the equation, since you are putting the coefficient of x to a negative
y = -x^3 - 4 lowers the equation by 4 on the y axis, setting the equation shown in the graph.
Answer:
simply by multiplying the hours with 60
eg 3hours
3×60
180minutes
You start by adding the integer:
39+75+120+50 =284
What you have left: 1/2, 1/3, 1/6
Make the 1/3 to 1/6:
1 (•1)/3 (•2) = 1/6
1 (•2)/6 (•1) = 2/6
1/6 + 2/6 = 3/6 = 1/2
1/2 + 1/2 = 1
284+1
285 feet • $5 = $1425
The solution to the equation is 3x-x+2=4.
