Answer:
Since we want to satisfy both at the same time, "x" must be equal or greater than 6.
Step-by-step explanation:
This product is formed by two square roots, since this mathematical operator can only be defined for positive values and zero, the number inside the root must be always greater or equal to 0, on both roots. Therefore:

and

Since we want to satisfy both at the same time, "x" must be equal or greater than 6.
Divide 80/3 which equals 26.6. So it take Courtney 26.6 minutes to walk 1 mile. Then divide 110/26.6 which equals 4.1.
Courtney walls 4.1 miles in 110 minutes.

Answer:
d) The binomial distribution with n = 4 and p = 0.5
Step-by-step explanation:
They re 10 cards consisting of 5 red cards and 5 black cards which are shuffled thoroughly and choosing at random. After choosing the cards are replaced back.
The probability of choosing a red card = number of red cards / total number of cards = 5 / 10 = 0.5
The probability of choosing a black card = number of black cards / total number of cards = 5 / 10 = 0.5
Since after choosing, the cards are replaced back and shuffled making the next draw independent of the previous draw repeated four times. This is a binomial distribution with n = 4 and p = 0.5
