You toss a coin and randomly select a number from 0 to 9 what is the probability of getting tails and selecting 3? 0.25 0.95 0 0
andre [41]
The correct answer is .05

To solve, find the decimal of each of the probabilities: 

Flipping Tails:  1/2 ----> .5

Picking 3:   1/10-----> .10

Now, multiply them together: 

.5 x .10 = .05

Hope this helps!

PLZ!!!! HELP ASAP!!! Problem is in the picture
Strike441 [17]

Step-by-step explanation:

pythagoras theorem: c²=a²+b²

Where c= longest side of a right angle triangle

AB= 6+r = c

AD= 12 =a

CD= r =b

(6+r)² = 12²+ r²

36+12r+r² =144 +r²

12r+r²-r²=144-36

12r=108

r= 108/12

r=9

HURRY PLS The length of time in hours of two airplane flights are represented by the following functions, where x is the number
mamaluj [8]

Answer:

h(x) = 0.0045x – 0.4

Step-by-step explanation:

The length of time in hours of two airplane flights are represented by the following functions, where x is the number of miles for the flight.

Flight A: f(x) = 0.003x - 1.2

Flight B: g(x) = 0.0015x + 0.8

Then the function  

h(x) = f(x) + g(x) = (0.003 + 0.0015)x + (-1.2 + 0.8) = 0.0045x - 0.4.

Therefore, the third option is the right option. (Answer)
