Answer:
μv =
σv= 
Step-by-step explanation:
Volume is found by multiplying the area and height. Since we're given both area and height of 10 and 5 cm respectively then
μv =A.h= 10*5= 50 cm^{3}
The standard deviation of the volume will be
σv= 0.3*10= 
Answer:
120 On edge i got it right
Step-by-step explanation:
Answer: 53
Step-by-step explanation: To get the answer we have to use the pythagorean theorem.
a² + b² = c²
28² + 45² = c²
784 + 2025 = c²
2809 = c²

c = 53

Answer:
x = 7/3
Step-by-step explanation:
Step 1: Write equation
6 + 3x = 12x - 15
Step 2: Solve for <em>x</em>
- Subtract 3x on both sides: 6 = 9x - 15
- Add 15 to both sides: 21 = 9x
- Divide both sides by 9: 21/9 = x
- Simplify: 7/3 = x
- Rewrite: x = 7/3
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
6 + 3(7/3) = 12(7/3) - 15
6 + 7 = 28 - 15
13 = 13
