Your teacher has the same hat with numbers 1,2,3,4,5,6,7,8,9,10,11 and 12 in it. She wants you to take two turns drawing a number. After the first time you draw, you will put the number back in the hat before drawing again. What are the chances that you will draw 4 two times in a row

0.0069 = 0.69%

Step-by-step explanation:

We have 12 total numbers. The chance of drawing exactly the number 4 is 1/12, as we have just one number 4 inside the 12 numbers.

As the number will be put back in the hat after the first draw, the probability for the second draw will be the same, as we will still have just one number for inside the 12 numbers.

As the events (the first and second draw) are independent from each other, we can just multiply the probabilities, so the probability of drawing 4 two times in a row will be:

(1/12) * (1/12) = 1/144 = 0.0069 = 0.69%

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.
