Answer:

D). (x, y) --> (0.9x, 0.9y).

Step-by-step explanation:

You multiply each coordinate to create a dilation . To get a smaller image the cinstant of multiplication is less than 1.

So it is D

Answer:

P(x = 0) = 0.004

P(x = 0) = 0.047

P(x = 0) = 0.211

P(x = 0) = 0.422

P(x = 0) = 0.316

Step-by-step explanation:

We are given the following information:

We treat a person who does not become a repeat offender as a success.

P(Success) = P(person who does not become a repeat offender) = 0.75

Then the number of people follows a binomial distribution, where

$P(X=x) = \binom{n}{x}.p^x.(1-p)^{n-x}$

where n is the total number of observations, x is the number of success, p is the probability of success.

Now, we are given n = 4

We have to evaluate:

$P(x = 0)\\= \binom{4}{0}(0.75)^0(1-0.75)^4 = 0.004$

$P(x = 1)\\= \binom{4}{1}(0.75)^1(1-0.75)^3 = 0.047$

$P(x = 2)\\= \binom{4}{2}(0.75)^2(1-0.75)^2 = 0.211$

$P(x = 3)\\= \binom{4}{3}(0.75)^3(1-0.75)^1 = 0.422$

$P(x = 4)\\= \binom{4}{4}(0.75)^4(1-0.75)^0 = 0.316$

Write the quadratic function in vertex form: f(x) = 4x2 + 2x -5

Andrei [34K]

Please use " ^ " to denote exponentiation: <span>f(x) = 4x^2 + 2x -5. To find the vertex form of this equation, complete the square:

f(x) = 4x^2 + 2x - 5
= 4(x^2 + (2/4)x) - 5
= 4(x^2 + (1/2)x ) -5
= 4(x^2 + (1/2)x + 1/16 ) - 4/16 - 5
= 4(x+1/4) - 21/4 <= in vertex form

Here h= -1/4 and k = -21/4. The vertex is at (-1/4, -21/4)</span>
