What is the difference between an observational study and an experiment

Answer: In observational study observer has no control on the variables but in an experiment experimenter has control over the independent variable to record the change on the dependent variable.

Step-by-step explanation:

In statistics , an observational study is a study in which a researcher just observe effects on subjects in a certain manner without interfering them.

On the other hand an experiment is a process which is done by experimenter to  demonstrate a known fact or create a discovery by applying some methods to the variables  .

The basic difference between an observational study and an experiment is in observational study observer has no control on the variables but in an experiment experimenter has control over the independent variable to record the change on the dependent variable.

in an observational study, the researchers do not control treatment, and in an experiment, they do (B)

A train leaves a station at 10:40 a.m. and arrives at its destination at 1:20 p.m. Find the distance between the stations if the average speed of the train was 60mph

Average speed   = distance / time

60 =  distance /   (13.20 - 10.40)

13.20 - 10.40  =  2 hours 40 minutes  =  2 2/3  hours

60 = distance / 8/3  = 3 d / 8     (where d = distance)

3d = 480

d = 480/3  = 160 miles Answer

Plastic cups comes in an 10-pack, but paper plates come in a 12 pack. What is the smallest number of plastic cups and paper plates you can purchase if you want to have the same number of each for an upcoming BBQ?

The answer is 60. You can find this out by finding the least common multiple of 10 and 12, which is 60 because 10x6=60 and 12x5=60. Hope this helps :)

A mixture of alcohol and water contains a total of 60 oz of liquid there are 12 oz of pure alcohol in the mixture was a percentage of the mixture is water what is the percent alcohol

The mixture contains 80% water and 20% alcohol.

Step-by-step explanation:

Given:

Total Amount of mixture = 60 oz

Amount of alcohol in the mixture = 12 oz

We need to find the percentage of water and percentage of alcohol in the mixture.

Solution:

First we will find the amount of water in mixture.

Now we know that;

Total Amount of mixture is equal to sum of Amount of alcohol in the mixture and amount of water in mixture.

so we can say that;

amount of water in mixture = Total Amount of mixture - Amount of alcohol in the mixture

amount of water in mixture =

Now we will find the Percentage amount of water.

Percentage amount of water can be calculated by dividing amount of water in mixture by Total Amount of mixture and then multiplying by 100.

framing in equation form we get;

Percentage amount of water =

Percentage amount of alcohol =

Hence The mixture contains 80% water and 20% alcohol.

11z/16+7z/8=5/16 how do you get the z alone?

11z ➗ 16 ➕ 7z ➗ 8 = 5 ➗ 16
x 8 x 8
11z ➗ 16 ➕ 7z = 5 ➗ 16 x 8
x 16 x 16
11z ➕ 7z = 5 x 8
18z = 40
➗ 18. ➗ 18
z=40 ➗ 18
z = 2.2

In a new york state daily lottery game, a sequence of four digits (not necessarily different) in the range 0-9 are selected at random. find the probability that three of the four digits are the same.

There are 10,000 (10*10*10*10) possible sequences. There are 4C3 ways, 4, of having exactly three digits be the same value. The differing digit can be any of the four positions. There are 10P2 ways, 90 (10*9), to choose the digits of the sequence since we have 10 choices for the digit to be repeated, then 9 more options or the differing digit. The product of the combination arrangements and permutation selection, 4*90, shows there are 360 sequences with three of the same digit. Thus the probability is 360/10,000 or 0.036 or 3.6%.

The probability that three of the four digits are the same in the lottery number is 0.036.

Total number of ways of arranging the 4 digits to make a lottery number is .

According to the question, three digits should be the same.

So, number of ways of arranging three same numbers in the lottery number of 4 digits is

Hence, the probability that three of the four digits are the same in the lottery number is

A square scarf is folded in half to form a rectangle. if the resulting rectangle has a perimeter of 15 inches, what are the area and perimeter of the square scarf?

Let x =  the length of each side of the square.

Therefore the dimensions of the rectangle are x and x/2.
Because the perimeter of the rectangle is 15 inches, therefore
2x + 2(x/2) = 15
2x + x = 15
3x = 15
x = 5 in.

The perimeter of the square scarf is 4x = 4*3 = 12 in.
The area of the scarf is 3*3 = 9 in²
