Find cos0, where 0 is the angle shown. Give an exact value, not a decimal approximation.

a)(x-2)^2+(y-1)^2=9

step-by-step explanation:

(picture explains)

then

in counting the number of heads in 4 coin flips, the probability that we get exactly one head is the probability that we get anyone of the following 4 outcomes: httt, thtt, ttht, or ttth. each has probability 1/16, so the probability to get exactly one head in 4 flips is 1/16 + 1/16 + 1/16 + 1/16 = 4/16 = 1/4.

this is impossible to do there is no way you can convert 35/4 into an improper fraction because it already is an improper fraction but you can simplify 35/4 = 8 3/4 or in a decimal 8.75.

hope i ! have a great rest of your week!
