Answer:
A. mean 71.33, median 86, mode 90 90 100 100, range 55
B. mean 79.41, median 36.5, mode 90, range 60
c. mean 73.16, median 2, mode 75 75 80 80, range 45
Step-by-step explanation:
mean is the average so add all numbers then divide by the number of number
mode is the number that is often seen
range subtract the smallest from largest or the other way around
median the middle number when lined all number from less to biggest

Say it out loud it goes, RS, ST.
If you put RS and ST together the angle RTS
Answer:
nj +k = p
Step-by-step explanation:
n = (p-k)/j
Multiply each side by j
nj = (p-k)/j *j
nj = p-k
Add k to each side
nj +k p-k+k
nj +k = p
124 square units
you just have to count the top, bottom, and a side and times by 2
Answer:
2
Step-by-step explanation:
Let's solve the given system of equations.
<u>Given system</u>
x +3y= 10 ----(1)
-2x -2y= 4 ----(2)
From (2):
-2(x +y)= 4
Dividing both sides by -2:
x +y= -2 ----(2)
Thus, options 3 and 4 are incorrect as x +y≠ -2.
(1) -(2):
(x +3y) -(x +y)= 10 -(-2)
Expand:
x +3y -x -y= 10 +2
2y= 12
Divide both sides by 2:
y= 12 ÷2
y= 6
Substitute y= 6 into (2):
x +6= -2
x= -6 -2
x= -8
Options (1) and (2) differs only by the value of the expression of -x +y. Thus, let's find its value in the given system of equations.
-x +y
= -(-8) +6
= 8 +6
= 14
Thus, option 2 is the correct option.
