There are three bags each containing 4 balls. Bag 1: three red balls, one blue ball. Bag 2: four red balls. Bag 3: two red balls, two blue balls.
What is the probability that the selected ball is from *bag 1* and is a *red ball*?

Answers

Answer 1

Answer: the bag 33.33 ect and the selecting of a red ball is 90%

Step-by-step explanation:

if a bag had three red balls, one blue ball and there are four ball intotal you would most likely get a red ball out of blue the other 10% is the blue ball and for the bags answer is just 100 divided by 3

Answer 2
I'm pretty sure the answer is 1/4. You have to multiply the probability of selecting bag 1 (1/3) by the probability of selecting a red ball (9/12). And then you simplify that answer.

Answer:

Sum = 4(2) + 5(1) + 6(2) + 7(0) + 8(2) + 9(1)

= 8 + 5 + 12 + 0 + 16 + 9

= 50

Mean = Sum/Frequency

= 50/8

= 6.25 rings

Answer:

Sum: 50Mean: 6.25

Step-by-step explanation:

You want the Sum and Mean of the number of rings as listed in the given table.

Frequency

The "frequency" line tells you the number of times the value above is included in the list. The expanded list of number of rings, taking frequency into account, is ...

  {4, 4, 5, 6, 6, 8, 8, 9}

The sum of these numbers is 50.

The average of these 8 numbers is 50/8 = 6.25.

Sum: 50Mean: 6.25

Answer:

Area of five squares = 1289.09 square units

Perimeter =  194.6 units

Step-by-step explanation:

Area of square and perimeter:

   First find the length of each square, then find the area of each square.

To find the area of five squares, add all the area of each square.

Side of square1 = 27 units

[tex]\sf Side \ of \ square2 = \dfrac{2}{3}*27=2*9 = 18 \ units\\\\Side \ of\ square3= \dfrac{2}{3}*18=2*6=12 \ units\\\\Side \ of \ square4=\dfrac{2}{3}*12=2*4=8 \ units\\\\Side \ of \ square5=\dfrac{2}{3}*8=\dfrac{16}{3}=5.3 \ units[/tex]

Area of square1 = 27*27 = 729 square units

Area of square2 = 18*18 = 324 square units

Area of square3 = 12*12 = 144 square units

Area of square4 = 8*8 = 64 square units

Area of square5 = 5.3*5.3 = 28.09 square units

Area of five squares = 729 + 324 + 144 + 64 +28.09

                                  = 1289.09 square units

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Perimeter of the composite figure = (27 + 27+27+9) + (18+18+6) +(12+12+4) + (8+8+2.7)+ (5.3+5.3+5.3)

                                                         = 90 + 42 + 28 + 18.7 + 15.9

                                                          = 194.6 units

the area of the five squares is 1289.09 square units

the perimeter is 194.6 units

Answer:

Step-by-step explanation:

First, you need to know all the numbers. 4 occurs twice, 5 occurs once, 6 occurs twice, 7 doesn't occur, 8 occurs twice, and 9 occurs once. So, if you laid it out, it would look like this: 4,4,5,6,6,8,8,9.

So to find the sum, you add all of those together which will give you 50.

To find the mean, you will need to find the sum (50) and divide that by the number of values which can be shown as : 50/8 or 6 1/4.

So, the sum would be 50 and the mean would be 6 1/4.

The double dot plot shows the runs scored per game by two baseball teams during a 10-game season. Compare the populations using measures of center and variation. Round your answers to the nearest tenth.

Answers

Mean of team A  < Mean of team B

MAD of team A < MAD of team B

Now, We can simplify as,

The double dot plot shows the runs scored per game by two baseball teams during a 10 game seasons.

Now, We can find the value of mean as,

For team A,

Mean = (2 x 1 + 3 x 1 + 4 x 4 + 5x 2 + 6 x 1 + 7 x 1) / 10

Mean = (2 + 3 + 16 + 10 + 6 + 7) / 10

Mean = 44 / 10

Mean = 4.4

For team B;

Mean = (2 x 1 + 5 x 2 + 6 x 4 + 7 x 2 + 9 x 1) / 10

Mean = 59/10

Mean = 5.9

MAD for both team are,

For team A;

MAD = |4.4 - 2| + |4.4 - 3| + 4 |4.4 - 4| + 2 |4.4 - 5| + |4.4 - 6| + |4.4 - 7| / 10

MAD = 2.4 + 1.4 + 1.6 + 1.2 + 1.6 + 2.6 / 10

MAD = 1.08

For team B;

MAD = |5.9 - 2| + 2|5.9 - 5| + 4 |5.9 - 6| + 2 |5.9 - 7| + |5.9 - 9| / 10

MAD = 3.9 + 1.8 + 0.4 + 2.2 + 3.1 / 10

MAD = 1.14

Hence,

Mean of team A  < Mean of team B

MAD of team A < MAD of team B
