The probability of tails of a weighted coin is 0.65. The number of tails is noted each of the 15 times the coin is tossed. If this procedure is repeated 100 times, what type of distribution is simulated? Select one:
a. A sampling distribution of the sample proportion with n = 15 and p = 0.65
b. A sampling distribution of the sample proportion with n = 100 and p = 0.65
c. A binomial distribution with n = 15 and p = 0.65
d. A binomial distribution with n = 2 and p = 0.65
e. There is not enough information to determine the type of distribution.

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

hope this

answer: 12

step-by-step explanation:

because yes

10 - 75

step-by-step explanation:

there's nothing attached so it's most likely anything in that range.

there are no choices to this, can you give us some choices so that i can answer it
