The Belgium 20-franc coin (B20), the Italian 500-lire coin (I500), and the Hong-Kong 5-dollar coin (HK5) are appropximately the same size. Coin purse 2 (C2) contains 6 of each of these coins. Coin purse 2 (C2) contains 9 B20's, 6 I500s, and 3 HK5's. A fair four-sided die is rolled. If the outcome is 1, a coin is selected randomly from C1. If the outcome belongs to 2,3,4 a coin is selected from C2. Find

(a) The probability of selecting a Belgium coin (Pr(B20))

(b) The probability that the coin was selected from C1, given that it was a Belgium coin

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24

it shoild be o

step-by-step explanation:

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.

step-by-step explanation:

f(gx)=f(1/x+2)

=(1/x+2)+2

=(1+2x)/2+2

=(1+2x+4)/2

= (2x+5)/2
