I need answers!!!!!!!!
aleksandrvk [35]

Answer:

a) 4.4583 b) Fiona

Step-by-step explanation:

First find the average of the numbers by adding them all together then dividing them by the amount of numbers given:

(85 + 88 + 90 + 91 + 93 + 96 + 97 + 97 + 98 + 98 + 99 + 105)\div12= 1137\div12= 94.75

Then find the difference between each number and the answer you got

(85 - 94.75) + (88 - 94.75) + (90 - 94.75) + (91 - 94.75) + (93 - 94.75) + (96 - 94.75) + (97 - 94.75) + (97 - 94.75) + (98 - 94.75) + (98 - 94.75) + (99 - 94.75) + (105 - 94.75)\div12

Which is

(9.75) + (6.75) + (4.75) + (3.75) + (1.75) + (1.25) + (2.25) + (2.25) + (3.25) + (3.25) + (4.25) + (10.25)\div12

Which comes out to

\frac{53.5}{12}=4.4583

ddd [48]

To find the percent, divide 9 by 27 to get a decimal, then multiply the decimal by 100 to get the percent:

9 / 27 = 0.333

0.333 x 100 = 33.3%

NEED HELP:
PSYCHO15rus [73]

Answer:

The radius is approx. 7.5

Let me know if it helps or if I got anything wrong!

Step-by-step explanation:

To find the circumference, you need to multiply the diameter by pi (3.14)

And for vice versa, just divide.

Since we don't know the diameter nor radius, we need to divide the Circumference (C) by pi (3.14)

47/3.14=14.968

Which is rounded up to 15.

We have now found the diameter.

We also know that the radius is half of the diameter

15/2=7.5
