Answer:
D
Step-by-step explanation:
When a function is vertically compressed, this means that the parent function is multiplied by a fraction between 1 and -1. The only answer choice that satisfies this is choice D, meaning that it is the answer. Hope this helps!
Answer:
0.050328
Step-by-step explanation:
Given that there are 10 coins, out of which 9 are fair and one is double headed.
P(selecting fair coin) = 0.9 and P(selecting double headed coin) = 0.1
P(H/fair coin)= 0.5 and P(H/doube headed ) = 1
Probability of getting in 1 toss head = Prob of selecting fair coin and getting head+ Prob of selecting double headed and getting head
=
This will be constant p for 10 trials going to be done because coin is replaced each time.
Also there are only two outcomes
X no of heads in 5 flips is Binomial with (5, 0.55)
P(x=5) = Reqd probability
=
(12 * 7 + n)8=12.5
(12 * 7 + n)= 100
N= 16. The new number will be 16. Hope this helps. :)
(n + 5)(n - 1)
= n^2 -n + 5n - 5 (FOIL)
= n^2 + 4n - 5
Answer:
Missing factor: (n - 1)
