It is written as 16-3 because it is 16 subtract 3 not 3 subtract 16 because that would come out to a negative integer.
Answer:
mean is 18.5 (add all values ÷ total number of values)
median is 16( arrange scores in ascending order and start removing scores from both the sides, 2 scores and up in the middle which were 14,18 add them and divide by 2)
omission of 42 will make the median 14(I'm not sure about this answer)
Answer:
X = 4
Step-by-step explanation:
That traingle is an isosceles triangle. You know this because the base angles, 45 and 45 are the same. Another characteristic of an iscosceles traingle is that the base sides ( in this case 4 and X ) are always the same
Your octagon has a central angle of 360 deg. Since you're speaking of an octagon, which implies that the octagon is made up of eight triangles, divide 360 deg by 8 to obtain the measure of each minor arc formed.
