The mean is the average of a set of numbers.
So if the remaining 40% of students score 100 points, and the 60% score like 50 points, then the mean would still be 70 points because of the 40% of students that scored super high.
So yes, it can be true.
Step-by-step explanation:
- 3x+5y=7b equation 1
- 2x+4y=1
2x=-4y+1
- x=(-4y+1)/2
- x=(-4y+1)/2 in equation 1
3×(-4y+1)/2+5y=7b
(-12y+3)/2+5y=7b
(-12y+3+10y)/2=7b
(-12y+3)/2=7b
-12y+3=14b
-12y=14b-3
- y=3-14b/12
- y=3-14b/12 in x=(-4y+1)/2
x=(-4×{3-14b/12}+1)/2
x=(-3+14b)/3+1/2
x=14b/3×1/2
Answer:
6.25 Miles
6 1/4
Step-by-step explanation:
3 + 2 = 5 MILES
1/2 you want the denominator to equal 4 so you times it by two
= 2/4
2/4+3/4= 5/4
this gives you one full mile and 1/4
add all together 5+1+1/4
I am picking this is right :)
Solve (1/8)^-3a = 512^3a
A=0
I took the assignment it’s right.
