Which of the following is not a possible r-value? a.0.6 b.0.3 c. -1.3 d. -o.6

Among following the value that is not possible fort a correlation coefficient is:

Option: C

C. -1.3

Step-by-step explanation:

A value greater than one (1) in any magnitude is not a possible r-value (i.e. the correlation coefficient) .

The value of r is always between -1 to +1

In statistics, the correlation coefficient measure the strength of the linear relationship between two variable ( i.e. dependent variable and independent variable) on a scatter plot.

Hence, option: C is the correct answer.

days of the week

step-by-step explanation:

javier earned more money then kyle, so that won't always be a constant term, but the days of the week do not change so that term is always constant.

edit: i meant

answer: c, the green line

step-by-step explanation:

there is no black line, eliminate b.

simple interest implies periodic payments, but the red line shows no payments, eliminate d.

simple interest has equal payments. if paid say every day, the graph is about a straight line (actually a stairstep).

the yellow line is not straight, eliminate a.

check: the green line is straight, answer is c.

simple interest with positive interest rate gives a straight line sloping up to the right. green line:

g(t) = $100 + ($200-$100) ÷ (20 years) × (t years)

= $100 + (4%/year) × ($100)(t years)

incidentally, the yellow line curving upward represents continuously compounded interest

y = $100 × 2^(t years / (14 assuming the yellow line hits $200 at 14 years. 2^0 is 1, so y(0) = $100; 2^(14/14) is 2, so y(14) = $200.
