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.

Answer:
261
Step-by-step explanation:
Here we can proceed two ways
WAY1 : using the order of operations
33 + 6( 2 + 36) = 33 + 6×(38)
=261
WAY2 : using distributive property
33 + 6( 2 + 36) = 33 + 6×2 + 6×36
= 33 + 12 + 216
=261

Answer on E2020
Answer:
-0
Step-by-step explanation:
W = -3
X = 3
Z = -9
Y = 6
-3 + 3 = 0
-9 + 6 = -3
-3 + 0 = -3
Then -3 is closest to -0! Cause when rounding, 4 and under as an example as 24 the round will be 20! And 25 will be 30
50.5 and 53.5
104-3=101 divided by 2=50.5 50.5+3 equals 53.5. 50.5+53.5=104
