Each of three friends flips a coin 76 times. The results for each friend are shown in the tables. Find
the relative frequency for the event "tails for each friend. If the friends combine their results to get
142 heads and 86 tails, what is the relative frequency for the event tails? Use pencil and paper.
Suppose each friend flips a coin 760 times. Is there a value you would expect the relative frequency
for the event "tails" to be close to?

answer: there are x+184 pages in olivia's book.

step-by-step explanation:

let the total number of pages in the book which olive has already read be x.

then if olive has 184 pages left to read, then the total number of pages are in olive's book= pages she has read+pages she has left to read

therefore, the total number of pages in olivia's book=

hence, there are x+184 pages in olivia's book.

6 spoons of sugar for every 21 cups of flour

step-by-step explanation:

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
