Answer:
1450$
Step-by-step explanation:
follow the basic steps to calculate the mean.
1. add up all of the numbers in the data set. in this case you would add up the all of the money since the question is asking for that.
2. divide by the amont of numbers there are.
1400+800+2150=4350
4350÷3=1450
hope this helped :)
Area of rectangle b=1/2 area of rectangle a=40/2=20 cm²
Length=8 cm
Width of rectangle b=20/8 =2.5 cm
Answer:
Account B
Step-by-step explanation:
Account A will give 92 thousand dollars
Account B will give 100 thousand dollars
Account B will earn the customer the greatest amount of interest.
You don't even need to do the math! 4.9 > 4.8. Investing less but for a longer period of time would give your more in your bank account.
Hope this helps!

Answer:
![C(x,y,z) = 4.2xy + 1.5xz + 1.5yz](https://tex.z-dn.net/?f=C%28x%2Cy%2Cz%29%20%3D%204.2xy%20%2B%201.5xz%20%2B%201.5yz)
Step-by-step explanation:
We are given the following information in the question:
A rectangular box has a length of x feet, a width of y feet, and a height of z feet.
Area of base =
![\text{Length}\times \text{Base}\\=x\times y](https://tex.z-dn.net/?f=%5Ctext%7BLength%7D%5Ctimes%20%5Ctext%7BBase%7D%5C%5C%3Dx%5Ctimes%20y)
Cost of building base = $4.20 per square foot
Total cost of building base =
![\text{Area of base}\times 4.20\\= 4.2xy](https://tex.z-dn.net/?f=%5Ctext%7BArea%20of%20base%7D%5Ctimes%204.20%5C%5C%3D%204.2xy)
Area of 4 walls =
![2(\text{Length}\times \text{Height} + \text{Base}\times \text{Height}) \\=2(xz+yz)](https://tex.z-dn.net/?f=2%28%5Ctext%7BLength%7D%5Ctimes%20%5Ctext%7BHeight%7D%20%2B%20%5Ctext%7BBase%7D%5Ctimes%20%5Ctext%7BHeight%7D%29%20%5C%5C%3D2%28xz%2Byz%29)
Cost of building base = $0.75 per square foot
Total cost of building 4 walls =
![\text{Area of 4 walls}\times 0.75\\= 1.5(xz+yz)](https://tex.z-dn.net/?f=%5Ctext%7BArea%20of%204%20walls%7D%5Ctimes%200.75%5C%5C%3D%201.5%28xz%2Byz%29)
Total cost of building box =
![C(x,y,z) = 4.2xy + 1.5(xz+yz)\\C(x,y,z) = 4.2xy + 1.5xz + 1.5yz](https://tex.z-dn.net/?f=C%28x%2Cy%2Cz%29%20%3D%204.2xy%20%2B%201.5%28xz%2Byz%29%5C%5CC%28x%2Cy%2Cz%29%20%3D%204.2xy%20%2B%201.5xz%20%2B%201.5yz)
Sample Response: The object will hit the ground after 5 seconds. You can rewrite the quadratic function as a quadratic equation set equal to zero to find the zeros of the function 0 = –16t2 + 80t + 0. You can factor or use the quadratic formula to get t = 0 and t = 5. Therefore, it is on the ground at t = 0 (time of launch) and then hits the ground at t = 5 seconds
What did you include in your response? Check all that apply.
I Rewrite the quadratic function as a quadratic equation set equal to zero: 0 = –16t2 + 80t + 0.
Use the quadratic formula to solve for the zeros.
Factor to solve for the zeros.
t = 0 and t = 5 seconds.
The object will hit the ground after 5 seconds.
