Answer:
The mean was 60%.
Explanation:
The mean is the average of your numbers. To calculate the mean you would have to add all the numbers together. Then, you’d divide your total amount by how many numbers you had to add together. For this example, you would add 34+90+87+34+55. This gives you a total of 300. Since you had 5 initial numbers, you would divide 300 by 5. You will come up with a final number of 60 which is your mean.
A)
Obw= 2*3,14*2 =12,56cm
Obw = 6,28*4 = 25,12m
Obw = 6,28*0,3 = 1,884cm
Obw = 6,28*10 = 62,8km
b)
Obw = 6,28*1 = 6,28cm
Obw = 6,28 * 1,5 = 9,42m
Obw = 6,28 *0,2 = 1,256cm
Obw = 6,28 *100 = 628m
c)
6,28*r = 10m
r≈1,59m
6,28*r = 1m
r≈0,159
6,28*r = 628mm
r=100mm
6,28*r = 3,5cm
r≈ 0,557cm
Answer:
Explanation:
Now imagine you were sailing with Ferdinand Magellan, who led the first group of ships to circumnavigate the Earth. Look up “circumnavigate” if you’re unsure what it means.
