Answer:
Step-by-step explanation:
Each term of the given arithmetic sequence is 6 more than the previous one. Thus, the next term is 26+6, or 32.
a(n) = 8 + 6(n-1)
Answer:
110 Degrees
Step-by-step explanation:
Every interior triangle equalls 180 degress. So you subtract what you already have from 180.
30+40+x=180
70+x=180
180-70=110
Answer:
x=8.16
Step-by-step explanation:
x=the money before
2x=doubled
3x=24.50
x=8.16
Answer:
(0,0)
Step-by-step explanation:
x^2+y^2=4^2
center: (0,0)
radius=4
To calculate the IQR, we need the radian, which is the middle number of each column, namely (86,82) for each exam.
Above the middle number, we have 5 values. The middle value (of the upper part) is Q3, which is on the third line, or (92,85).
Below the middle number, we also have 5 values. The middle (of the lower half) is Q1, which is on the 9th line (80,78)
The IQR is the difference between Q3 and Q1, namely
(92-80, 85-78) = (12, 7)
Since 12>7, we conclude that the IQR of the mid-term is higher than the final.
