A = -11
B= -12
This is because of how calculations work in negatives. Because they are both negative they work similarly to addition
Answer:
0.025 = 2.5% probability that a given class period runs between 51.5 and 51.75 minutes.
Step-by-step explanation:
An uniform probability is a case of probability in which each outcome is equally as likely.
For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.
The probability that we find a value X lower than x is between c and d is given by the following formula
For this problem, we have that:
. So
0.025 = 2.5% probability that a given class period runs between 51.5 and 51.75 minutes.
Answer:
- R= 0.2
- 2
Step-by-step explanation:
explaining the answer to 1
I'll explain everything so you understand.
The correlation coefficient tells us about the strength of the relationship between the variables. In other words, it tells us how well the data fits on the line of best fit.
So, the closer the points lie on the line of best fit the stronger the relationship and correlation.
The further the points lie from the line of best fit, the weaker the correlation
It is important to note that the correlation coefficient (r) always lies between -1 and 1.
So, the closer the value of r lies to -1 or 1 the stronger the relationship between the variables.
The closer the value of r is to 0 the weaker the relationship between the variables and the weaker the correlation.
explaining the answer to 2
the correlation coefficient (r) always lies between -1 and 1 so it can't be 2.
Hope this helps.
A quantity representing the power to which a given number or expression is to be raised, usually expressed as a raised symbol beside the number or expression.
Answer: they are parallel
Step-by-step explanation:
find slope of line m:
Use y2-y1/x2-x1
your m equation --> 9-15/10-3 which makes the slope of m = -6/7
find slope of line n:
Use y2-y1/x2-x1
your n equation --> 3-9/9-2 which makes the slope of n = -6/7
The slopes are the same, therefore line m and line n are parallel.
