A. Median number is the middle number. We can cross one off from left to right to get 4.
B. Interquartile range is Q3-Q1. Q1 is 2 and Q3 is 5, so the interquartile range is 3.
C. I don't know the original set, but an outlier can affect the mean.
1. 2sin²(-2490) + tan(1410)
2(0.25) - 0.6
0.5 + 0.6
1.1
2.
Step-by-step explanation:
arithmetic sequence.
an = an-1 + c = a1 + (n-1)c
c is in our case 2 (every new shape has 2 more vertices).
we have a a1 = 3.
an = 3 + 2(n-1)
so,
a21 = 3 + 2(20) = 3 + 40 = 43
the 21st shadow will have 43 vertices.

Question 1
----------------------------------------------------------------
a² + b² = c²
9² + 14² = c²
c² = 81 + 196
c² = 277
c= √277
c = 17cm (Rounded to the nearest whole number)
----------------------------------------------------------------
Ans: The Slanted height is 17cm (Answer C)
----------------------------------------------------------------
----------------------------------------------------------------
Question 2
----------------------------------------------------------------
Lateral area of the cone = πrl
1080π = π(60)l
l = 1080π ÷60π
l = 18.0cm
----------------------------------------------------------------
Ans: The slanted height is 18.0cm (Answer D)
