Answer:
Radius, r = 26.57 cm and diameter = 53.14 cm
Step-by-step explanation:
Given that,
The circumference of a coin, C = 167 cm
We need to find the radius and the diameter of the coin.
The formula for the circumference of a circle is given by :

Where
r is radius of coin

Diameter, d = 2r
d = 2(26.57) cm
= 53.14 cm
Hence, this is the required solution.
Answer:
Worked 5 hours: $550
Worked 7 hours: $2,750
Worked 12 hours: $6,600
Step-by-step explanation:
5+7+12=24
13200/24 = 550
(5)*(550) = 2,750
(7)*(550) = 3,850
(12)*(550) = 6,600
The set that is more variable is the daily temperature as they won't be clustered but rather spread out.
<h3>How to know the set that's more variable?</h3>
The mean of the temperature will be:
= (51 + 37 + 53 + 27 + 91 + 50 + 50 + 83 + 83 + 90)/10
= 615/10
= 61.5
The mean of the precipitation will be:
= (4.5 + 3.8 + 1.4 + 2.4 + 2.8 + 4.6 + 4.7 + 2.3 + 1.5)/10
= 28/10
= 2.8

Answer:
9 : 3
Step-by-step explanation:
To get from 21 to 3 we divided 21 by 7, therefore we have to do the same to the other side and so we get...
63 / 7 = 9
Therefore 63 : 21 = 9 : 3
