6+ 9.43 = 15.43
3 is the radius so the diameter is 6.
d • pi is the equation for circumference.
6 • pi is approximately 18.85
and because its a semi circle, you divide that by half and get 9.43
then add the diameter and half the circumference which = about 15.43 and thats the perimeter.
Answer:
Step-by-step explanation:
Slope m = 1/3 and intercept c = -1
The equation of line
y = mx + c
y = 1/3x - 1
Answer:
Mean = 4.8875
Median = 4.6
Mode = 4.5 and 7.7
Step-by-step explanation:
Mean is the sum of total of data divided by the sample size
Sum total = 1.5 + 4.7 + 6 + 7.7 + 7.7 + 4.5 + 2.5 + 4.5
Sum total = 39.1
Sample size = 8
Mean = 39.1/8
Mean = 4.8875
To get the median we need to first rearrange
1.5, 2.5, 4.5, 4.5, 4.7, 6, 7.7, 7.7
Median = 4.5 + 4.7/2
Median = 4.6
Hence the median is 4.6
Mode is the value occuring the most. Since 4.5 and 7.7 both occurs twice, hence the mode of the data is 4.5 and 7.7
845* (100-62)%
=845*38%
=845*38/100
=32110/100=321,1
