Answer:
Option D) 0.92
Step-by-step explanation:
We are given the following probability distribution in the question:
x: 0 1 2 3 4 5
P(X): 0.78 0.14 0.03 0.01 0 0.04
We have to find the probability that a randomly selected student will be absent no more than one day.
Thus, we have to evaluate:
0.92 is the probability that a randomly selected student will be absent no more than one day.
Thus, the correct answer is
Option D) 0.92
The Answer Is C The fist poster is the proper representation, because find the areas compare the paintings to the first poster it is 360 to 3240 which shows the poster is 9x bigger but compared to the second one it is out of proportion for the painting and first poster
Answer:
The cost of the steel will be $38 per square meter.
Step-by-step explanation:
The company wants to make an oil container in the shape of a cylinder. The container will have a height of 7 m and radius of 6 m. The container will be made from steel both the top and bottom is included. This means the total surface area of the cylinder will be made by steel. The total cost of the steel is given by $18,613.92 . The cost of the steel per square meter can be calculated below.
Total surface area of the cylinder = 2πr(r + h)
where
r = radius
h = height
r = 6 m
h = 7 m
Total surface area of the cylinder(container) = 2πr(r + h)
Total surface area of the cylinder(container) = 2π × 6(6 + 7)
Total surface area of the cylinder(container) = 12π(13)
Total surface area of the cylinder(container) = 156 × 3.14
Total surface area of the cylinder(container) = 489.84 m²
Cost per square meter = 18613.92/489.84
Cost per square meter = $38 per square meter.
The cost of the steel will be $38 per square meter.
