A bag contains 6 purple marbles and 7 white marbles. One marbles is drawn at random and not replaced. Then a second marble is dr
KonstantinChe [14]

Answer: 7/26

Step-by-step explanation:

Number of purple marbles = 6

Number of white marbles = 7

Total number of marbles = 13

The probability of first drawing a white marble will be = 7/13

The probability of drawing a purple marble the second time will be = 6/12 = 1/2

The probability that the first marble is white and the second one is purple will now be:

= 7/13 × 1/2

= 7/26

Note that since there are 13 marbles, when the first purple marble is drawn, there'll be 12 marbles left.

What is the sum of 9c+(8+3c)?
mixas84 [53]
<span>9c+(8+3c)      
9c+8+3c     (collect like terms)

9c+3c+8
12c+8

12c+8 is the answer.
im not sure if your teacher also wants the answer to be in simplest form so im going to do that below as well:

12c+8      (4*3=12 and 4*2=8. you can take out a 4 from those 2 numbers)

4(3c+2) (this is the simplest form of </span>9c+(8+3c)<span>)

Alex73 [517]

Complete Question

A magazine provided results from a poll of 500 adults who were asked to identify their favorite pie. Among the 500 ​respondents, 12 ​% chose chocolate​ pie, and the margin of error was given as plus or minus 5 percentage points.What values do ​ \r p ,  \ \r q, ​n, E, and p​ represent? If the confidence level is 90​%, what is the value of \alpha ​?

Answer:

a

   \r p is the sample proportion   \r  p  =  0.12

   n is the  sample size is  n  =  500

   E is the  margin of error is E  =  0.05

   \r  q represents the proportion of those that did not chose chocolate​ pie i.e                        \r  q  =  1-  \r p

b

   \alpha  = 10\%

Step-by-step explanation:

Here

    \r p is the sample proportion   \r  p  =  0.12

   n is the  sample size is  n  =  500

    \r  q represents the proportion of those that did not chose chocolate​ pie i.e  

      \r  q  =  1-  \r p

      \r  q  =  1-  0.12

      \r  q  = 0.88

     E is the  margin of error is E  =  0.05

Generally \alpha is the level of significance and it value is mathematically evaluated as

     \alpha  = ( 100 -  C  )\%

Where  C is the confidence level which is given in this question as  C =  90  \%

So  

    \alpha  = ( 100 -  90  )\%

    \alpha  = 10\%
