Answer:

see below

Step-by-step explanation:

1). 8 radii are shown, there are 8 straight lines going from the center of the circle to the edge of the circle

2) diameter = d, radius = r. given radius r ,

d = 2r

d = 2(14.5) = 29

the diameter is 29 cm

3)using d = 2r

7x+5 = 2(13) = 26

7x = 21

x = 3

4)the length of the diameter is increased 3 times

d1 = 2r,

d2 = 2(3r) = 6r

we see that the diameter whose radius is 3 times longer is 3 times larger than the diameter whose radius is 1 times as long.

5) they can find the diameter of the circular path, then find the radius, go from one point on the circular path and go r distance

An advertising campaign is canceled before launch with probability 0.10, in which case the marketing company is fired with proba
Feliz [49]

Answer:

0.2231 (22.31%)

Step-by-step explanation:

defining the event F = the marketing company is fired, then the probability of being fired is:

P(F)= probability that the advertising campaign is cancelled before lunch * probability that marking department is fired given that the advertising campaign was cancelled before lunch + probability that the advertising campaign is launched but cancelled early  * probability that marking department is fired given that the advertising campaign is launched but cancelled early        ....   (for all the 4 posible scenarios where the marketing department is fired)

thus

P(F) =0.10 * 0.74 + 0.18 * 0.43 + 0.43 * 0.16 + 0.29*0.01 = 0.2231 (22.31%)

then the probability that the marketing department is fired is  0.2231 (22.31%)
