Drag and drop an answer to each box to correctly complete the derivation of a formula for the area of a sector of
a circle.
Suppose a sector of a circle with radius r has a central angle of 0. Since a sector is a fraction of a full
circle, the ratio of a sector's area A to the circle's area is equal to the ratio of the central angle to the
measure of a
rotation of the circle. A full rotation of a circle is 21 radians. This
proportion can be written as 4 = 1
Multiply both sides by arra and simplify to get
where
is the measure of the central angle of the sector and r is the radius of the
circle.

You and a friend went to the movies. you spent half your money on tickets. then you spent 1/4 of the money on popcorn, $2 on candy, and $3 on a soda. if you have $1 left, hiw much money did u take to the movies?

In a test for esp (extrasensory perception), the experimenter looks at cards that are hidden from the subject. each card contains either a star, a circle, a wave, a cross or a square.(five shapes) as the experimenter looks at each of 20 cards in turn, the subject names the shape on the card. when the esp study described above discovers a subject whose performance appears to be better than guessing, the study continues at greater length. the experimenter looks at many cards bearing one of five shapes (star, square, circle, wave, and cross) in an order determined by random numbers. the subject cannot see the experimenter as he looks at each card in turn, in order to avoid any possible nonverbal clues. the answers of a subject who does not have esp should be independent observations, each with probability 1/5 of success. we record 1000 attempts. which of the following assumptions must be met in order to solve this problem? it's reasonable to assume normality 0.8(1000), 0.2(1000)%30 approximately normal 0.8(1000), 0.2(1000)% 10 approximately normal srs it is reasonable to assume the total number of cards is over 10,000 it is reasonable to assume the total number of cards is over 1000
