Mean of eight observations is 25. If one observation 11 is excluded , find the mean of the remaining.
Answers
Answer:
Mean = 27
Step-by-step explanation:
Given mean = 25
No of observations (N) = 8
We know,
Mean = Sum / N
25 = Sum / 8
Sum = 25 x 8
Sum = 200
Since an observation 11 is removed,
New sum = 200 - 11 = 189
New no. of observation (N) = 8 - 1 = 7
Now,
Mean of remaining observations = New Sum / New N
= 189/7
= 27
Answer:
mean=25
n=8
sum of observation=?
we have
mean=sum/n
sum=25×8=200
if one observation is excluded
sum will be =200-11=189
[n]no of observation = 8-1=7
new mean =new sum/new n=189/7=27
the mean of the remaining is 27

The Cobb-Douglas production model is a function that relates production outputs with a combination of different inputs. Agricultural data from 44 countries around the world, concerning agricultural production Q, labor L, capital K, fertilizer F, and hectares of arable land H, can be used to create an agricultural production model for countries using a Cobb-Douglas function given by
Q= 3.41 L^0.266 .K^2.06 F^0.299.H^1.41
The exponents in the Cobb-Douglas model are called elasticities. Find the percentage increment in production if a country has a 1% increase in Labor.
Answers
Answer:
0.266 percent
Step-by-step explanation:
With labor increasing by 1 percent, we are to find how much level of production would also increase given the coubglas function in the question.
Level of production = ∆Q/Q
We differentiate the function Q with respect to Labour, L.
∆Q/∆L = 0.266Q/L
∆Q/Q = 0.266∆L/L
∆L/L = 1
∆Q/Q x 100 = 1 *0.266
= 0.266%

the measures of the angles of a triangle are shown in the figure below. solve for x
Answers
Answer:
the the figure shown x=7
Answer:
7°
Step-by-step explanation:
7x + 5 °+ 36° + 90 °= 180° ( being sum of angles of triangle )
7x + 131° = 180°
7x = 180 °- 131 °
7x = 49°
x = 49° / 7
x = 7°

Answers
Answer:
m<1 = 97°
Step-by-step explanation:
<1 and 83° are same-side interior angles. Same-side interior angles are supplementary. This implies that:
m<1 + 83° = 180°
Therefore:
m<1 + 83° - 83° = 180° - 83° (subtraction property of equality)
m<1 = 97°
Answer:
<1=97°
steps:
<1+83=180 co interior angle
<1=180-83=97°
