Answer:
15 - 5x = 5 · 3 - 5 · x = 5(3 - x)
Answer:
0.078125.
Step-by-step explanation:
This is a geometric sequence with first term a1 = 20 and common ratio r = 10/20 = 5/10 = 0.5.
nth term = a1 r^(n -1) so here:
9th term = 20(0.5)^(9-1)
= 20(0.5)^8
= 0.078125.
Answer:
-9/5
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-2-7)/(0-(-5))
m=-9/(0+5)
m=-9/5
Answer: 283
Step-by-step explanation:
To find the median, you have to first arrange the figures in the distribution in ascending order:
210, 249, 316, 443
As this is an even distribution, the Median will be found by adding up the second and third numbers and then dividing by 2:
= (249 + 316) / 2
= 283
