i know that the top one is incorrect but i don’t understand why or how to the correct answer.
by proportion, the number of students with a dog is predicted to be:
(16/50) * 280
= (8 / 25) * 280
= 89.6 so it is 90 students.
they do have enough to pay for their dinner including dinner tax and gratuity
so they have $30.
their dinner costs $21
taxes are $21 *1.06=22.26
tip is 22.26*1.15=25.599
so they do have enough to pay for their dinner
i think it is
a formal letter is a letter the you would send to a king
possible error in volume is 25.12 inches
radius of cylinder = 4 inches with error of ±0.1 inch.
height of cylinder = 10 inch
to find : resulting possible error in volume of cylinder
we use differentiation to find the possible error in volume i.e. we find .
volume of a cylinder =
where r is radius of circular base and h is the height of cylinder
differentiating the equation with respect to r we get:
now, it is given that the possible error in radius is 0.1 i.e. . substituting values in above equation we get:
thus we find that possible error in volume is 25.12 inches
