Answer:
12
Step-by-step explanation:
C a circular puzzle in diameter of the pierrc are about the same size
4y - 7 = 5 - 2y
Add 2y to both sides.
6y - 7 = 5
Add 7 to both sides.
6y = 12
Divide both sides by 6
y = 2
Answer:
Step-by-step explanation:
To find the expected no of broken cabinets for each strategy.
If A transport all the furniture
Suppose X₁ = number of furniture A broken
X₁ follows a binomial with n = 3, p = 0.10
E(X₁) = np
E(X₁) = 3 × 0.1
E(X₁) = 0.3
If A transport two (2) cabinets & B transport one (1) cabinet
expected no. of the broken cabinet by A out of 2 is
= 2 × 0.1
= 0.2
Suppose X₂ denotes the no of broken furniture by B
E(X₂) = np
where n= 1 and p = 0.15
E(X₂) = np
E(X₂) = 1 × 0.15
E(X₂) = 0.15
Thus. the expected number of broken cabinets = 0.2 + 0.15 = 0.35
Answer:
- A) The radius of the sphere is 3 millimeters.
- B) The circumference of the sphere is 6π millimeters.
Step-by-step explanation:
Based on the answer selections, it appears we need to find the radius and circumference of the sphere. We can start with the volume formula in terms of the radius:
V = (4/3)πr³
36π = (4/3)πr³
(36π)(3/(4π)) = r³ = 27 . . . . . . mm³
r = ∛27 = 3 . . . . mm³
Then the circumference is ...
C = 2πr = 2π(3 mm) = 6π mm
The radius is 3 mm; the circumference is 6π mm.
