ves as Democrats, 45% as Independents, 21% as Republicans, and 2% as Other.23 When asked, "Should the government in Washington do everything possible to improve the standard of living of all poor Americans?," 23% of the Democrats, 18% of the Independents, 4% of the Republicans, and 15% of Others agreed. Given that a person agrees that the government in Washington should do everything possible to improve the standard of living of all poor Americans, use Bayes’ rule to find the probability the person thinks of him- or herself as a Democrat.

Answer:

0.71875

Step-by-step explanation:

Probability that a person thinks of himself as Democrat = P(A)= 0.32

Probability that a person agress that the govt. in Washington should do everything possible to improve the standard of living of poor= P(B)

Probability that a Democrat agress that the govt. in Washington should do everything possible to improve the standard of living of poor P(A ∩ B) = 0.23

P(B/A) = P(B∩A)/ P(A)

P(B/A)= 0.23/0.32

P(B/A) = 0.71875

Please help, i do not get this.

Answer:

k(x) = |x - 4| - 2

Step-by-step explanation:

So we know that k(x) is shifted 4 untis to the right and 2 units down. In an absolute value function, the value you move to the left will be positive and the value you move to the right will be negative. Since we are moving to the right, our value will be negative.

When you shift the function up or down, you will either subtract or add that value out side the absolute value. Since we are shifting down 2 units, that means we will be subtracting by 2.

Best of Luck!

The first term in a sequence is -2 and the common ratio is 3. What is the sixth term of the sequence?
AlekseyPX
It's the Geometric Sequence.

The n<span>-th term of a geometric sequence with initial value </span>a<span> and common ratio </span>r<span> is given by:
</span>
a_n=a_1\cdot r^{n-1}\ for\ n\in\mathbb{N^+}

We have:

a_1=-2;\ r=3;\ n=6

Substitute:

a_6=-2\cdot3^{6-1}=-2\cdot3^5=-2\cdot243=-486

Answer: The sixth term is equal -486.

Given the function
nika2105 [10]

\left \{ {{7x+6\:\:\:\:\:\:x

f(-1)

Solve

-7\cdot \:1+6x                          Swap the negative sign

-7+6x                               Multiply the numbers

-7+6x+7                  Add 7 to both sides

6x                                       Simplify

\frac{6x}{6}                                       Divide both sides by 6

x                                        Simplify

-7\cdot \:1+12x                     Swap the negative sign

-7+12x                          Multiply the numbers

-7+12x+7              Add 7 to both sides

12x                                   Simplify

\frac{12x}{12}                                  Divide both sides by 12

x                                      Simplify

The midpoint AB is M (-1,1). If the coordinates of A are (-6,-3), what are the coordinates of B
Ratling [72]

Answer:

coordinates of B is ( 4,5)

Step-by-step explanation:

If there two points (x1,y1) and (x2,y2) on a plane then coordinates of mid point is given by

m = (x1+x2)/2  , (y1+y2)/2

Given

m = (-1,1)

A= (-6, -3)

we have to point b

let point b be (x,y)

Then m (-1,1) is given by (-6+x)/2 , (-3+y)/2

(-6+x)/2 = -1

-6 + x = 2*-1 = -2

x = -2+6 = 4

also

(-3+y)/2 = 1

=> -3 + y = 2

=> y = 2 + 3 = 5

Thus , coordinates of B is ( 4,5) answer
