In a certain manufacturing process, it is known that, on average, 1 in every 100 items is defective.
Rashid [163]

Answer:

A. 0.009899

B. 0.005624

Step-by-step explanation:

Data:

Let the probability that an item is defective = \frac{1}{100}

The probability that the item is not defective = \frac{99}{100}

The probability that the fifth item is defective = \frac{1}{100}* \frac{98}{99}

                                                                            = 0.009899

Probability that one in 5 items is defective  = 0.005624

ANSWER ASAP AND I WILL MARK YOU BRANLIEST. Tomas makes balloon sculptures at a circus. In 96 minutes, he uses 160 balloons to ma
Alexus [3.1K]

Answer:

Step-by-step explanation:

(96 minutes)/(32 sculptures) = (96/32 minutes)/sculpture = (3 minutes)/sculpture

It takes 3 minutes to make one sculpture.

(160 balloons)/(32 sculptures) = (160/32 balloons)/sculpture = (5 balloons)/sculpture

It takes 5 balloons to make one sculpture.

(160 balloons)/(96 minutes) ≈ 1.7 balloons used per minute.

Find the VOLUME of this composite solid.
Black_prince [1.1K]

Answer:

  (294π +448) cm³ ≈ 1371.6 cm³

Step-by-step explanation:

The half-cylinder at the right end has a radius of 7 cm, as does the one on top. Together, the total length of these half-cylinders is 8 cm + 4cm = 12 cm. That is equivalent in volume to a whole cylinder of radius 7 cm that is 6 cm long.

The cylinder volume is ...

  V = πr²h = π(7 cm)²(6 cm) = 294π cm³

__

The cuboid underlying the top half-cylinder has dimensions 4 cm by 8 cm by 14 cm (twice the radius). So, its volume is ...

  V = LWH = (4 cm)(8 cm)(14 cm) = 448 cm³

Then the total volume of the composite figure is ...

  (294π +448) cm³ ≈ 1371.6 cm³
