Algebraic inequalities can be solved in the same way in which algebraic equations are solved.
(5-0)^2+(3-3)^2
25+0
The square root of 25 is 5
The distance is 5.
In this case you the probabilities can be multiplied similarly to if you flipped a coin twice. .45 * .80 = .36
Answer: B
Reason:
44 + x
66
x
22
Also when we have a greater and equal to sign (
), it will be a filled in circle.
Thats why its by.
Answer:
a) TRUE
b) FALSE
c) FALSE
d) TRUE
e) FALSE
Step-by-step explanation:
a)
TRUE because the slope of the correlation line is 2 and this is the rate of change of y respect to x
b)
FALSE
The correlation coefficient r is always between -1 and 1, so it can never be greater than one
c)
FALSE
A student might expect that there is a positive correlation between the age of their laptop and its resale value only if after collecting a large enough sample of data that relates age of the student and price of resale of their laptop, he or she finds that there is a positive correlation coefficient r>0
d)
TRUE
If there is a positive correlation, then the greater the x, the greater the y
e)
FALSE
If there is no correlation between the independent and dependent variables, then the value of the correlation coefficient must be 0.
