The graph shows number of tickets a person has received versus the number of accidents they have been in. if the trend continues, how many accidents would a person who has received 10 tickets be in?

we could do things the hard way: find the equation of the regression line and then substitute 10 for x. or we could extend the blue regression line about one more unit to the right, to x = 10, and then estimate the number of accidents:

draw a vertical line thru x = 10, and extend the blue line, and find the point of intersection of these two lines, and then draw a horiz. line through that point of intersection.

you will find that this horiz. line intersects the y-axis at about 6.

this goes to say that if a person has rec'd 10 tickets, he or she will likely have about 6 accidents.

note that it's risky to give much credence to predictions from a regression line when the extension lines mentioned here go beyond the actual measured data.

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.
