Answer:
Yes, it is a matched pairs design.
Step-by-step explanation:
Assuming that the twins used in the experiment are identical, this can be treated as a matched pairs designed. Although there are two individuals receiving different treatments, they are genetically similar enough for this to be considered a matched pairs design (One individual subjected to two different treatments).
If you miss 9 questions, the how many did you get right?
85 - 9 = 76
So now you got 76 out of 85 correct or 76/85...
Now if you just do the fractional division that is described by the fraction you will get the answer. The fraction bar literally means "divided by", so the fraction means...
76 divided by 85 which equals...
.8941
Now to convert to percentage we multiply by 100 (move the decimal 2 places to the right)
.8941 x 100 = 89.41% Round to nearest one percent...
89%
Answer: 24.5 inches
Step-by-step explanation:
Luca used 587.19 inches for 35 players and 2 coaches:
= 35 + 2
= 37 people.
The inches per person used for headband is:
= 587.19/37
= 15.87 inches
Luca then used 302.05 inches for just players who number 35 to make wristbands. Inches used per player is:
= 302.05/35
= 8.63 inches
Fabric used for each player is therefore:
= 15.87 + 8.63
= 24.5 inches
