Step-by-step explanation:
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.
Answer:
The correct answer is A.
Step-by-step explanation:
face value = 1.86 , charges are 20% more for smokers
⇒ Charges = 20% of 250000 = $50000
Total charge = Charge × face value
= 50000 × 1.86 = $93000
face value = 1.86 , charges are 18% more for smokers
⇒ Charges = 18% of 250000 = $45000
Total charge = Charge × face value
= 45000 × 1.86 = $83700
face value = 2.07 , charges are 25% more for smokers
⇒ Charges = 25% of 250000 = $62500
Total charge = Charge × face value
= 62500 × 2.07 = $129375
face value = 2.25 , charges are 15% more for smokers
⇒ Charges = 15% of 250000 = $37500
Total charge = Charge × face value
= 37500 × 2.25 = $84375
Hence, The option A. is correct that is Aaron is paying the smallest premium possible with company B
Answer: 7
Step-by-step explanation:
Step 1: Subtract 3 from both sides.
6a+3−3=45−3
6a=42
Step 2: Divide both sides by 6.
6a
/6
=
42
/6
a.129.6+16.2
= 145.8
b.129.6×16.2
= 2099.52
c.129.6÷16.2
= 8
d.129.6−16.2
= 113.4
e.192.4+14.8
= 207.2
