Suppose that 40% of all families in your city have a dog, and you want to create a simulation to predict the probability that it will take at least 4 random picks from the population to find one family with a dog.

Choose all that correctly describe the use of random digits as a simulation to predict the probability.

Use ten digits ( 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9 ), and let 40% of the them represent families with dogs.

Let the digits 0, 1, 2, 3 represent families with dogs, and (4, 5, 6, 7, 8, 9) represent families without dogs.

Find the probability that a 0, 1, 2, or 3 is not generated within the first four random picks.

10.416 meters per second

step-by-step explanation:

distance=1 00 meters

time= 9.6 seconds in decimal form or 9 3/5 as a mixed number

average speed= 100/9.6

=10.416 meters per second or 10 52/125 as a mixed number.

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
