Answer: 5/2
Step-by-step explanation:
Using slope formula m = rise/run
Answer:
Step-by-step explanation:
I will assume that the scale factor is 2.5
A'(-5,2.5) True
AB || A'B' True
?? What does ABAB" mean?
A'B' is an enlargement of AB True
Since you provide no information about the median salary, i'm gonna use the national data, whcih is around $ 13,000 per year
Cost of education for 2 year = $30,000
Since he's still working in those 2 years, he'll earn = $ 26,000
Which means he just need to work for around half a year to cover the remaining $4,000 , so i think the answer is 2.5 years
hope this helps
Answer:
-56c+ 30
Step-by-step explanation:
4c + 10(3 – 6c)
Rearrange terms
4c + 10(3 – 6c)
4c+10(-6c+3)
Distribute
4c+10(-6c+3)
4c-60c+30
Combine like terms
4c-60c+30
-56c+30
Common factor
-2(28c-15)
Distribute
-2(28c-15)
-56c+30
Solution:
-56c+30
Answer:
Where
and
We select a sample of n=16 and we are interested on the distribution of
, since the distribution for X is normal then we can conclude that the distribution for
is also normal and given by:

Because by definition:



And for this case we have this:


Step-by-step explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Solution to the problem
Let X the random variable that represent the IQ scores of a population, and for this case we know the distribution for X is given by:
Where
and
We select a sample of n=16 and we are interested on the distribution of
, since the distribution for X is normal then we can conclude that the distribution for
is also normal and given by:

Because by definition:



And for this case we have this:
