You estimate that there are 47 marbles in a jar. The actual amount is 52 marbles. Find the percent error. Round to the nearest tenth of a percent if necessary.

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.

it costs $20 to interview each person for a survey. find the cost to obtain a +- 3% margin of error.
