Answer:
3 miles per hour
Step-by-step explanation:
Jessica is walking home from a friend's house.
After 2 minutes she is 0.8 miles from the home and after 12 minutes she is 0.3 miles away fro her house.
Her rate will be = (change in distance)/change in time
= (0.8-0.3)/(12-2)
= 0.5/10
= 0.05 miles per minute
Now we will convert timings from minutes to hour.
Or = 0.05×60
= 3 miles per hour
Answer:
The probability of the heads up on the first three flips and not on the last two flips will be 1/32.
Step-by-step explanation:
As, the probability of head up when one time coin is flipped is 1/2. And it is said in the question that you must get heads in the first three flips.
So, for the first three flips the probability is = (1/2)^3 = 1/8
And for the last two flips you want to get not heads up.
Then, the probability is = (1/2)^2 = 1/4
Hence, your overall probability will be = 1/8 × 1/4 = 1/32 .
