6,15,16,20,13,5,10,16 find the mean
2 answers:
6 + 15 + 16 + 20 + 13 + 5 + 10 + 16 = 101/8 = 12.6
mean: 12.6
Hello There!
To find the mean we have to add up all the numbers and divide by how many numbers there are.
6+15+16+20+13+5+10+16
Now, I will add 2 numbers at a time to make it easier for myself.
21+36+18+26
Once I add up these numbers, I will get a sum of 101
Finally, I divide 101 by 8 and get a quotient of 12.625

Let the length of one of the diagonals be 2x and the other be 2y, then
cos (76/2) = x/10
x = 10 cos 38 = 7.88 cm
sin (76/2) = y/10
y = 10 sin 38 = 6.16 cm
Answer:

Step-by-step explanation:
The second option ! 2.54 - 2.3 = 0.24
Answer:
1) 250 meters= 0.25 km
2) 12 meters= 0.012km
3) 1 meter= 0.001 km
The constant of proportionality is 1000 meters in 1km (1000 meters)
I think there’s a mistake on the second part because 1 meter does not equal to 1000km. but I did part 1 for you!
