Answer:

Use an ruler if you must listen to explanation.

Step-by-step explanation:

So this is actually very easy so it already tells you the Width= Feet is 80. But the Length = Feet is 6 greater any time you see something that says Number? Greater it means Multiply so multiply 6x80=480 so your length will be 480 Ok that's true But! The Width isn't answered your paper/screen Says, The perimeter of a rectangular outdoor patio is 80 ft. The length is 6 feet greater than the width what are the dimersions of the patio. Dimersion's what is it? The number.

So your confused?

Here are a list of things you can use,

A ruler

A protractor

Or A Tape Measuerer

Pardon if spelled wrong.

Anyway the perimeter is 80 ft.  Here's what i would do i would use a ruler and see how long the width is then times that with 6 and you should get your answer i cannot use my ruler because picture is to small even when clicked this should help you.

Hope this helped!

An accounting firm has recently recruited six graduates: three men and three women. Three of the graduates are to be selected at
solong [7]

Answer:

a) The probability tree is constructed below

b) the probability that at least two women will be selected is 0.500

Step-by-step explanation:

Given the data in the question;

a) The probability tree is as follows;

                                                 3 men, 3 women

                                                            ↓

           _______________________|________________________

            ↓                             ↓                                  ↓                               ↓

         3 men                    2 men                          1 man                        0 men

      0 women                1 woman                     2 woman                   3 women

b) the probability that at least two women will be selected

p( at least two women would be selected) = P( there are 2 women out of 3 ) + P( there 3 women out of 3

so

p( at least two women would be selected) = C

³C₂ × ³C₁ / ⁶C₃ + ³C₃³C₀ / ⁶C₃  

= 3!/(2!(3-2)!) × 3!/(1!(3-1)!)  / 6!/(3!(6-3)!) + 3!/(3!(3-3)!) × 3!/(0!(3-0)!) / 6!/3!(6-3)!)

= 3 × 3 / 20 + 1 ×  1 / 20

= 9/20 + 1/20

= 0.45 + 0.05

p( at least two women would be selected) = 0.500

Therefore, the probability that at least two women will be selected is 0.500

An urn contain 2 white marbles, 3 green marbles, and 5 red marbles. A marble is drawn and then replaced. Then a second marble is
11111nata11111 [884]

<u>Answer:</u>

1/5

<u>Step-by-step explanation:</u>

To find this you would need to multiply the probability of pulling a white marble to the probability of pulling out a green marble.

1)First you would need the probability of pulling out a white marble. There are 10 marbles in total and out of those 2 are white. So the probability of pulling out a white marble would be 2/10. If you simplify that you would get 1/5 for the probability of pulling out a white marble.

2)Next, you would find the probability of pulling out a green marble. Using the same process that we used to find the probability of pulling out a white marble, we would find the answer to be 3/10. All that we did here was <em>green marbles/total marbles</em>. By filling that in we got 3/10 for the probability of pulling out a green marble.

3)Now all that is left is doing <em>probability of pulling a white marble × probability of pulling out a green marble</em>. This would be 1/5 × 3/10. After solving the answer would be 3/15 which we would simplify down to 1/5 as our final answer.
