The two equations would be, respectively, y=12,000-400x and y=6000-300x
Set the two equal to one another and solve for x.
The answer is 60 hours
Answer:
210
Step-by-step explanation:
2ab=2(35)(3)=210
Answer: The width of the court is 30 feet.
Step-by-step explanation:
We know that the area of a rectangle is given by :-
Area = length x width (1)
Given : A standard-size volleyball court has an area of 1,800 square feet.
The length of the court is 60 feet.
To find : The width of the court.
According to (1) , we have
![1800 = 60\times \text{width}](https://tex.z-dn.net/?f=1800%20%3D%2060%5Ctimes%20%5Ctext%7Bwidth%7D)
Then,
![\text{Width}=\dfrac{1800}{60}=30](https://tex.z-dn.net/?f=%5Ctext%7BWidth%7D%3D%5Cdfrac%7B1800%7D%7B60%7D%3D30)
Hence, the width of the court is 30 feet.
Answer:C
Step-by-step explanation:
Answer:
The proportion of memory sticks that will be scrapped is 0.3 = 30%.
Step-by-step explanation:
Uniform probability distribution:
An uniform distribution has two bounds, a and b.
The probability of finding a value of at lower than x is:
The probability of finding a value between c and d is:
The probability of finding a value above x is:
Distributed uniformly between 3mm and 13 mm.
This means that ![a = 3, b = 13](https://tex.z-dn.net/?f=a%20%3D%203%2C%20b%20%3D%2013)
Calculate the proportion of memory sticks that will be scrapped:
![P(X > 10) = \frac{13 - 10}{13 - 3} = \frac{3}{10} = 0.3](https://tex.z-dn.net/?f=P%28X%20%3E%2010%29%20%3D%20%5Cfrac%7B13%20-%2010%7D%7B13%20-%203%7D%20%3D%20%5Cfrac%7B3%7D%7B10%7D%20%3D%200.3)
The proportion of memory sticks that will be scrapped is 0.3 = 30%.
