Answer:
there are 70 possible choices for the four locations to apply the new ointment
Step-by-step explanation:
Since we have a total of 8 locations ( 4 to the new ointment and 4 to the control) , each one can be chosen and since the order of the locations that are chosen for the new ointment is not relevant , then we know that the number of choices is given by the number of combinations of 4 elements in 8
number of combinations = 8 possible locations to the first ointment * 7 possible locations to the second ( since the first one was already located) * 6 to the third * 5 locations for the fourth / number of times the same combination is repeated ( the same locations but in different positions) = 8*7*6*5 / (4 possible positions for the first ointment* 3 possible positions to the second ointment (since the first one was already located * 2 possible positions of the third * 1 possible position of the fourth)
therefore
number of combinations = 8*7*6*5/(4*3*2*1 ) = 8!/((8-4)!*4!) = 70 possible combinations
thus there are 70 possible choices for the four locations to apply the new ointment
Answer:
Length = 56
Step-by-step explanation:
Perimeter = Length + Length + Width + Width
Perimeter = 2L + 2W
2L + 2W = 204
2L + 2(46) = 204
2L + 92 = 204
Subtract 92 from both sides
2L = 112
Divide both sides by 2
L = 56
Length = 56
Answer:
The first 3 terms of the sequence 
are:
Step-by-step explanation:
Given the sequence
Here 
represents any term number in the sequence
Determining the first term
substitute n = 1 in the sequence to determine the first term
Determining the 2nd term
substitute n = 2 in the sequence to determine the 2nd term
Determining the 3rd term
substitute n = 3 in the sequence to determine the 3rd term
Therefore, the first 3 terms of the sequence are:
