Answer:

C. The samples are independent because there is not a natural pairing between the two samples.

Step-by-step explanation:

Independent samples are stand-alone samples.  Their values do not give information about other values in another samples. They cannot be altered. Examples: To test the effectiveness of a particular drug in managing diabetes, a group of people is placed on the active drug. Another group is placed on a placebo. The two samples are independent because their values are taken from two different set of groups or people.

But a dependent sample is usually taken from the same group to test for the effectiveness of a drug before and after treatment.

On a certain hot summers day, 648 people use the public swimming pool. The daily prices are $1.50 for children and $2.25 for adu
ehidna [41]

Answer:

252 children and 395 adults

Step-by-step explanation:

Make a linear system of equations, where x represents the number of children and y represents the number of adults

x+y=648

1.50x+2.25y=1269

solve using substitution, so y=648-x,

then substitute this into the second equation, so you get 1.50x+2.25(648-x)=1269,

solve for x and you will get x equals the 252

then substitute this into the first equation, so you get 252+y=648

solve and you will get y=395

WITCHER [35]

Answer:

The answer to your question is 7 times

Step-by-step explanation:

Data

Percent of accuracy = 35%

Times she is at bat = 20

Times she hit the ball = ?

Process

1.- Use proportions to solve this problem

20 times will be the 100%  because is the total number of times she is at bat.

                     20 times ------------------ 100%

                       x            ------------------   35%

                       x = (35 x 20) / 100

                       x = 700 / 100

                       x = 7

2.- Conclusion

From 20 times she is at bat, she will hit the ball 7 times.
