It is a vertical stretch of factor ⅔, which will make the graph wider
thanks for all the point ur the best
Answer:
Step-by-step explanation:
In order to solve this quadratic, we have many methods. We can factor, complete the square, or use the quadratic formula. I'm going to factor since it's the easiest method.
To factor, find two numbers that when multiplied equal a(c) and when added equal b.
a=1, b=-4, and c=-5.
So we want two numbers that when multiplied equals 1(-5)=-5 and when added equals -4.
-5 and 1 are the possible numbers. Therefore:
Answer: 25.34 inches of precipitation
Step-by-step explanation: you have to subtract the precipitation from pensacola by the precipitation from Key West. so when you subtract the 2 you get 25.34 inches
Answer:
Step-by-step explanation:
a) P(K) = 0.7
b) P(R|K) = 1
c) P(K|R) = P(KnR) /P(R)
= P(K) x P(R|K) / ( P(K) x P(R|K) + P(K') P(R|K')
= 0.7 x 1 / ( 0.7 x 1 + (1-0.7) x 1/N)
= 0.7/(0.7 + 0.3/N)
d) P(K|R) > 0.99
0.7/(0.7 + 0.3/N) > 0.99
N > 42.86
N = 43 will be the value of N that will ensure that P(K|R) >99%
