Answer:
Probability is : 1/30240= 0.000033068
Step-by-step explanation:
You pick 5 digits (0-9) at random without replacement, and write them in the order picked.
The probability that you have written the first 5 digits of your phone number is -
As there are no repeats, the choice to choose from decreases at each step making it 10,9,8,7,6.
F(t)= $100 x h + 300 A reasonable domain is (1,2,3) and the range is ($400,$500,$600)
Answer:
The correct options are 3, 4 and 5.
Step-by-step explanation:
It is given that an air balloon begins it's decent to the ground at 1000 ft above the ground and falls at a rate of 50 ft per minute.
It means the initial height of air balloon is 1000. So, the y-intercept is (0,1000).
The ball falls at a rate of 50 ft per minute. So, the rate of change is
The height of balloon is defined as
Where, x is time in minutes.
The balloon will reach the ground when h(x)=0
Therefore the options 3, 4 and 5 are correct.
