Answer:

8, 6, 3, 2, 1

Step-by-step explanation:

g(x) = -x + 3

using g(x),

g(-5) = (-1 x -5) + 3

= 5 + 3

= 8

g(-3) = (-1 x -3) + 3

= 3 + 3

= 6

g(0) = 0 + 3

= 3

g(1) = -1 + 3

= 2

g(2) = -2 + 3

= 1

Urn 1 contains two white balls and one black ball, while urn 2 contains one whiteball and ve black balls. One ball is drawn at r

matrenka [14]

Answer:

4/5 is the probability of white ball from urn 2

Step-by-step explanation:

Correct statement of the question is ;

Urn 1 contains two white balls and one black ball, while urn 2 contains one white bait and five black balls. One ball is drawn at random from urn 1 and placed in urn 2. A ball is then drawn from urn 2. It happens to be white. What is the probability that the transferred ball was white?

We solve it ;

Probability of taking out balls from urn 1

<u>a) for white ball</u>

$P(w_{1} )=\frac{2}{3}$

<u>b) for balck ball</u>

$P(b_{1} )= \frac{1}{3}$

If one ball is taken from urn 1 and put in urn 2 (which readily contains one white and five black balls)

Probability of taking out balls from urn 2

<u>a) for white ball</u>

$P(w_{2} )=P(\frac{w_{2} }{w_{1} } ).P(w_{1} )+P(\frac{w_{2} }{b_{1} } ).P(b_{1} )$

$=\frac{2}{7} . \frac{2}{3} + \frac{1}{7}. \frac{1}{3} =\frac{5}{21}$

Then the probability that white ball was transferred from urn 1 to urn 2 is;

$P(\frac{white ball transfer }{w_{2} } )= \frac{P(\frac{w_{2} }{w_{1} } ).P(w_{2} )}{P(w_{2}) }$

$=\frac{ \frac{2}{7}.\frac{2}{3} }{\frac{5}{21} }$

$=\frac{4}{5}$

So, the probability that white ball is drawn from urn 2 is 4/5

What is the value of x?<br><br><br><br> Enter your answer in the box.<br><br> x =

Olin [163]

The arcs in the corners of the triangle mean that all 3 angles are the same.

Because the 3 angles are all the same this means that all 3 sides are also the same.

To solve for X, we can set 2 of the equations to equal each other and solve for x:

6x-3 = 3x +6

Add 3 to each side:

6x = 3x +9

Subtract 3x from each side:

3x = 9

Divide both sides by 3:

x = 9/3

X = 3

And if you replace x with 3 in each of the equations, they all equal 15.
