You use a line of best fit for a set of data to make a prediction about an unknown value. the correlation coefficient for your data set is -0.015. how confident can you be that your predicted value will be reasonably close to the actual value?

a: 2.75
b: 11
c: 13.75
d: 16.5

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

step-by-step explanation:

first you will have to convert 3/4 into a decimal

which is .75

then you will have to divide 1.5 by .75

which is 2

no you have to divide

shift 4 units up, and 1 unit left.

it will translate f(x) = 3^x to g(x) = 3^(x+1) + 4

answer:

1.14285714286

step-by-step explanation:

divide 40 into 35 and you will get your answer
