The answers are:
P(9, 2) = 72
P(5, 5) = 120
P(7, 7) = 5040
These are examples of permutations. The problems are asking us to find the total number of ways an event can happen.
In the first case, P(9, 2), we are asked to find the ways that 2 things can be chosen out of a group of 9.
9 x 8 = 72
P(5, 5) = 5 x 4 x 3 x 2 x 1
P(7, 7) = 7 x 6 x 5 x 4 x 3 x 2 x 1
Answer: x= 30 because the elevated point is 25 degrees and if you add it with 110 and subtract it with 35 you get 110 + 25 = 135 and 35 - 25 = 15 135 + 15 = 150 and 180 - 150 = 30. so it is 30 degrees. (tell me if i was wrong cause i'm 90% sure this is it but i don't know.)
Answer: The incidence of skin cancer (melanoma) has been underestimated.
Step-by-step explanation: The frequency of melanoma is more than 20 times higher in whites than in black Americans. In general, the risk of melanoma in the course of life is approximately 2.6% (1 in 38) for whites, 0.1% (1 in 1.000) for black people and 0.58% (1 in 172) for Hispanics. the risk for each person can be affected by a different number of factors.
