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:
18 miles per hour is an outlier
the outlier decreases the mean speed
Step-by-step explanation:
the low number of 18 is way different from the other numbers being in the 30's and 40's
this 18 will bring the mean of all the numbers own because it is a smaller number.
The vertical angles from the attached image will be; 1 and 4; 2 and 3; 5 and 8; 6 and 7.
The Linear pair angles would be: 1 and 3; 2 and 4; 5 and 7; 6 and 8; 1 and 2; 3 and 4; 5 and 6; 7 and 8
<h3>How to identify angle theorems?</h3>
A) From the attached image, the side roads resemble 2 parallel lines cut by a transversal.
Now, if we consider the roads to be very fat lines, then it means that the main road is the transversal while the two side roads are parallel to each other.
B) Vertical angles are defined as angles that are opposite of each other The vertical angles from the attached image will be; 1 and 4; 2 and 3; 5 and 8; 6 and 7.
The Linear pair angles would be: 1 and 3; 2 and 4; 5 and 7; 6 and 8; 1 and 2; 3 and 4; 5 and 6; 7 and 8when two lines cross
The supplementary angles would be: 3 and 5; 4 and 6
C) If a fourth road is constructed, it will be perpendicular to the main road, or perpendicular to the two side roads, and it will form a right triangle.
Thus, the acute angles of the triangles will be complementary because their sum will be 90°

Answer:
The answer is 7.
Step-by-step explanation:
4 divided by 7 is 0.571428 these just keep repeating over and over again so the closest dividable number of 6 (6 is how many digits there are before it repeats) is 1998 so the 2nd digit in .571428 is 7 hope this helps.
