Subjects for the next presidential election poll are contacted using telephone numbers in which the last four digits are randoml
elixir [45]

Answer: 0.3439

Step-by-step explanation:

Total number of digits : 10

The number of digits except zero =9

The probability of selecting non-zero number :-

\dfrac{9}{10}=0.9

Then, the probability that one such phone number , the last four digits do not include any zero:-

\text{P(no zero )}=(0.9)^4

Then , the probability that for one such phone​ number, the last four digits include at least one 0:-

\text{P(at-least one zero )}=1-(0.9)^4=0.3439

Hence, the probability that for one such phone​ number, the last four digits include at least one 0 is 0.3439 .

Write a proportion and find the missing side lengths. show work!! 30 points.
miv72 [106K]

Answer:

Step-by-step explanation:

34 . since the given two figure are similar their corresponding sides are proportonal.

let the missing side be x

take these ratios

15/18 = x/30

do cross multiplication

18*x = 30*15

18x = 450

x = 450/18

x = 25

therefore missing side is 25

35.since they are also similar their corresponding sides are proportional.

let the missing side be x

for this take these ratios

8/12 = 10/x

do cross multiplication

12*10 = 8*x

120/8 =x

15 =x

therefore missing side is 15.
