Answer:
C. P- value < 0.04 0.05
Step-by-step explanation:
hello,
we were given the sample size, n = 200
also the probability that the psychic correctly identifies the symbol on the 200 card is

using the large sample Z- statistic, we have

= 
= 1.7678
thus the P - value for the hypothesis test is P(Z > 1.7678) = 0.039.
from the above, we conclude that the P- value < 0.04, 0.05
Answer:
f(x)=3(x-4)(x+3)
Step-by-step explanation:
Quadratic function follows the f(x) = ax^2 +bx+c pattern
f(x)=3(x-4)(x+3) after multiplying out is equal to
f(x)=(3x-12)(x+3) = (3x^2+9x-12x-36) = (3x^2-3x-36)
f(x) = (3x^2-3x-36)
where
a = 3
b = -3
c = -36
2x+7=?
X=6
2(6)+7=
12+7=19
In six years, the tree will be 19ft
2x+7=44
Minus seven on both sides
2x=37
Divide two from both sides
X=18.5
Thus, it will take 18 and a half years for the tree to reach 44ft
