Answer:

$0\le P\le 1$

Step-by-step explanation:

The probability of an event is a number describing the chance that the event will happen.

Definition: The probability of an evant is

$P=\dfrac{\text{Number of favorable outcomes}}{\text{Number of all possible outcomes}}$

1. An event that is certain to happen (Number of favorable outcomes = Number of all possible outcomes) has a probability of 1.

2. An event that cannot possibly happen (Number of favorable outcomes = 0) has a probability of 0.

3. If there is a chance that an event will happen, then its probability is between 0 and 1.

Thus,

$0\le P\le 1$

What is the mean absolute deviation of the data set?

Ronch [10]

Answer:

the mean absolute deviation of the data set is 2.

Step-by-step explanation:

To calculate the mean absolute deviation of a data set, we need to follow the following steps:

Step 1: Calculate the mean.

Step 2: Calculate how far away each data point is from the mean (always keeping a possitive distance).

Step 3: Calculate the mean of the deviations.

Step 1: The mean of the data set is:

Mean = (12 + 10 + 10 + 8 + 6+ 7 + 7 + 12)/8 = 72/8 = 9

Step 2:

{12 -9, 10-9, 10-9, 9-8, 9-6, 9-7, 9-7, 12-9} = {3, 1, 1, 1, 3, 2, 2, 3}

Step 3: (3 + 1 + 1 + 1 + 3 + 2 + 2 + 3)/8 = 2

In conclusion, the mean absolute deviation of the data set is 2. Which corresponds to the option B.

What is slope intercept form of -6+3y=-3x

shutvik [7]

Esay, first what you have to do us move -6 to the right side and now you will have 3y=-3x+6, what you want to do next is to divide 3y by both sides and your final answer is y=-x+2, hope this helps.

An online furniture store sells chairs for $50 each and tables for $550 each. Every day, the store can ship a maximum of 32 piec

Hunter-Best [27]

Answer:

you have to sell 6 tables to meet all requirements

Step-by-step explanation:

chairs=$50x

tables=$550x

24 chairs×50= $1200

4100-1200= $2900

take $2900 and divide by $550 to find the exact number of tables which is 5 but selling 5 tables and 24 chairs doesnt reach the $4100 mark so I rounded up to 6 tables which doesnt surpass the maximum number of furniture(32) but beats the $4100 mark

For your sports equipment store, you purchase a case containing 24 canisters of tennis balls for $60. You in turn charge $4 for

Montano1993 [528]

Answer:

60%

Step-by-step explanation:

Given data

we are told that 24 canisters cost $60

hence the cost per canister = 60/24= $2.5

The selling price per canister= $4

%mark up = selling price-cost price/cost price *100

Substitute

%mark up = 4-2.5/2.5 *100

%mark up = 1.5 /2.5 *100

%mark up = 0.6 *100

%mark up = 60%

Hence the percent mark up is 60%
