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.
{(3x)}^{2}-2(3x)(5)+{5}^{2}
−2(3x)(5)+5
2
{(3x-5)}^{2}
It is only one line because a<span> set of points is collinear if they lie on a single straight line. This is very common to be applied in mathematics</span>
Answer:
A
Step-by-step explanation:
The probability of rolling a 3 is
1
/6 since there is 1 three and there are 6 sides total. The probability of rolling an even number is 1
/2 since there are 3 even numbers and 6 total sides. Multiply 1
/6 and 1
/2 and the correct answer is 1
/12
