Answer:
New Average of New List = 87.5
Step-by-step explanation:
Average is the arithmetic mean (M) of observations.
M = ΣX / N
where ΣX = sum of all observations , N = number of observations
Given : M = 90 ; N = 40
M = ΣX / N
90 = ΣX / 4
ΣX = 90 x 4
ΣX = 360 [ Of Old List of 4 numbers ]
New ΣX of new list of 4th new number = Old ΣX - Old 4th No. + New 4th No.
New ΣX = 360 - 90 + 80
New ΣX = 350
New Average (Mean M) = New ΣX / N
New M = 350 / 4
New M = 87.5
Answer:
Option 2 and 4
Step-by-step explanation:
Area of the big rectangle to fit small ones:
Area of small rectangles:
- A= 11*7=77
- B=2*11=22
- C=6*6=36
- D=6*5=30
- E=13*4=52
Now, the answer options:
- 3E+2B= 3*52+2*22= 200 > 165 ⇒ no
- A+B+C+D= 77+22+36+30= 165 ⇒ yes
- 2C+2D+2B= 2(36+30+22)=176 > 165 ⇒ no
- A+4B= 77+4*22= 165 ⇒ yes
- E+C+D+3B= 52+36+30+22= 140 < 165 ⇒ no
