Answer:
The mean average of all "six" students is 36.83.
Step-by-step explanation:
Mean:
The mean is the sum of all scores divided by the number of scores.
A group of five students have a mean test score of "34.2." Another student has a score of 50.
This means that the sum is given by:
What is the mean average of all "six" students?
Sum of 6 students is 221. So
The mean average of all "six" students is 36.83.
t is the number of hours Lamar worked as a tutor
We know that he worked for 92 hours total, so he worked 92-t hours as a waiter.
So his earnings are: 7t + 8(92-t) = 736 -t dollars
This expression seems logical as if Lamar worked 0 hours as a tutor and 92 as a waiter his earnings would be 8*92 = 736
If he worked as a tutor for 92 hours it would be 7*92= 644
736-92= 644
So our expression seems to be working.
Figure=1rectangle+2 semicircles
1semicircle=1/2circle
2 (1/2 circles)=1 circle
figure=1 rectangle+1 circle
area of rectangle=legnth times width
area of circle=pir^2
so the width of the rectangle=diameter of the circle
widht=4
diameter=2r
d/2=r
width=d=4
4/2=r=2
area of circle=3.14 times 2^2
are of circle=3.14 times 4
aera of circle=12.56
area of rectangle=11 times 4
area=44
total=add them up
12.56+44=56.56 cm^2
