![P(x =x) [{\frac{1}{6} ;x =1,2,3...6]](https://tex.z-dn.net/?f=P%28x%20%3Dx%29%20%5B%7B%5Cfrac%7B1%7D%7B6%7D%20%3Bx%20%3D1%2C2%2C3...6%5D)
Given random experiment of tossing of 6 sided dice is follow above distribution
Therefore, suppose x₁, x₂ ...x₁₀ are 10 independent and indentical random variable which represent first 10 rolls
Average of first 10 rows equals
now suppose ,
x₁₁,x₁₂, ...x₁₅ are 5 independent and identical random variable which represent last 5 roll
average of last 5 roll is
Therefore,
3.5 - 3.5 = 0

Answer:
1 marble
Step-by-step explanation:
The volume of steel is ...
V = LWH
V = (30 cm)(20 cm)(10 cm) = 6000 cm³
The volume of a marble is ...
V = (4/3)πr³ = (4/3)π(11.273 cm)³ = 6000 cm³
The block of steel will make 1 marble.
Answer:
$37.50
Step-by-step explanation:
$60 x .25 = $15 (tip)
$60 (meal) + $15 (tip) = $75
$75 ÷ 2 (# of people splitting the cost) = $37.50
Answer:
B
Step-by-step explanation:
The function is cubic (the highest power is 3), so it can't be even. It's either odd or neither.
We can either graph the function, or we can test that it's symmetrical about the origin by seeing if f(x) = -f(-x).
f(x) = -2x³ + 3x²
f(-x) = -2(-x)³ + 3(-x)²
f(-x) = 2x³ + 3x²
f(x) ≠ -f(-x), so the function is neither even nor odd.
