Answer:
The no. of traditional type birdhouses are 4 and the no. of lavish type birdhouses are 3.
Step-by-step explanation:
Let x be the no. of traditional type birdhouses
The more traditional type takes 4 pieces of wood and 2 hours to build.
One house requires wood = 4
x houses requires wood = 4x
One house requires time = 2 hours
x houses requires time = 2x
Let y be the no. of lavish type birdhouses
The more lavish type takes 10 pieces of wood and 7 hours to build.
One house requires wood = 10
y houses requires wood = 10y
One house requires time = 7 hours
y houses requires time = 7y
Now we are given that he has a total of 46 pieces of wood and 29 hours to work,
So, equations becomes :
Plot these equations on graph
---Blue line
---Green line
Refer the attached figure
The intersection point provides the solution
Intersection point : (4,3)
So, x = 4 and y = 3
Hence the no. of traditional type birdhouses are 4 and the no. of lavish type birdhouses are 3.
Answer:
Step-by-step explanation:
a. Given p=0.15.
-The mean of a sampling proportion of n=5000 is calculated as:
-The standard deviation is calculated using the formula:
Hence, the sample mean is μ=750 and standard deviation is σ=0.0050
b. Given that p=0.15 and n=1000
#The mean of a sampling proportion of n=1000 is calculated as:
#-The standard deviation is calculated as follows:
Hence, the sample mean is μ=150 and standard deviation is σ=0.0113
c. For p=0.15 and n=500
#The mean is calculated as follows:
#The standard deviation of the sample proportion is calculated as:
Hence, the sample mean is μ=75 and standard deviation is σ=0.0160
