Answer:
Mean: 85.55
Median: 90
Mode: 95
Rage of Data: 35
Step-by-step explanation:
B) the mean is widely preferred as the best measure of central tendency because it is the measure that includes all the values in the data set for its calculation, and any change in any of the scores will affect the value of the mean.
C) the mean would become smaller.
Answer:
y=2.75x+3
Step-by-step explanation:
$2.75 per sandwich (coefficient)
Solid $3 fee (y-intercept)
y=mx+b ---> y=2.75x+3
Answer:
Option B. 8 mi, 9 mi, 2 mi
Step-by-step explanation:
The option A doesn't have a set of numbers which could be the lengths of the sides of a triangle. The numbers 1,9,10 mean that the longest side is exactly the sum of the others. The only possible way is they lie in the same line, no triangle is formed
Option C gives the numbers 1,9,11. It's impossible to have a side of 11 when you have the sum of the others less than 11. The maximum extension of the other sides (forming a line) won't be enough to reach the length of 11
Option D is also infeasible for the same reason as the option A. The three lines must be aligned to be connected in its extremes
Option B is the only one who can provide a set of possible lengths of a triangle since the sum of the shortest sides is greater than the third. If we open wide enough the angle between the 2 mi side and the 8 mi side, we would eventually connect the 9 mi side and form a triangle
Yes, because both triangles are divisible by a certain number to equal to each side of each triangle.
