12. The
answer is B because the sum of any two sides of a triangle must be greater than the other side.
A. 4 → 4 + 4 is not GREATER than 8
B. 8 → 4 + 8 is greater than 8 and 8 + 8 is greater than 4
C. 12 → 4 + 8 is not GREATER than 12
D. 16 → 4 + 8 is not GREATER than 16
13. The central angle containing the green beans is 360° - (195°+98°) = 67°.
If the diameter of the circle is 12 then the circumference = πd = 12π.

× 12π≈7.013
So the
correct answer is A67/360 represents the portion of the circle which is green beans and you multiply it by the circumference to find the length of that arc.
Answer:
The probability that a randomly selected x-value lies between μ − 2σ and μ is the shaded area under the normal curve shown. P(μ − 2σ ≤ x ≤ μ) = 0.135 + 0.34 = 0.475
Step-by-step explanation:
Answer:
The container can hold 18 gallons
Step-by-step explanation:
Assume the container can hold x gallons
∵ The container is
full with water
∵ It can hold x gallons
→ Multiply
by x to find the number of gallons in the container
∴ The number of gallons in the container =
x
∵ 4 gallons of water pouring out
∵ It is
full
→ Multiply
by x to find the number of gallons left in it
∴ The number of gallons left in the container =
x
→ The difference between the numbers of gallons is 4 gallons
∵
x -
x = 4
→ Subtract the terms of the left side
∴
x = 4
→ Multiply both sides by 9
∴ 2x = 36
→ Divide both sides by 18
∴ x = 18
∵ x represents the full of the container
∴ The container can hold 18 gallons
