Step-by-step explanation:
we divide both sides by 4 to single out the X
(4X) / 4 = (2/3)/4
simplify
X = 2/12
Answer:
ok and thank you for point
Answer:
The probability that a defective rod can be salvaged = 0.50
Step-by-step explanation:
Given that:
A machine shop produces heavy duty high endurance 20-inch rods
On occasion, the machine malfunctions and produces a groove or a chisel cut mark somewhere on the rod.
If such defective rods can be cut so that there is at least 15 consecutive inches without a groove.
Then; The defective rod can be salvaged if the groove lies on the rod between 0 and 5 inches i.e ( 20 - 15 )inches
Now:
P(X ≤ 5) = 
= 0.25
P(X ≥ 15) = 
= 0.25
The probability that a defective rod can be salvaged = P(X ≤ 5) + P(X ≥ 15)
= 0.25+0.25
= 0.50
∴ The probability that a defective rod can be salvaged = 0.50
Answer:
377.62 m³
Step-by-step explanation:
V = 16 × 3.95 × 8 - 8 × 3.95 × (8 - 3.95)
V = 377.62
Angle B = 54°
Step-by-step explanation:
complimentary means they add up to 90
54 + 36 (angle A) = 90
also x= 51
