A box contains twelve 16 GB pen drives and eighteen 32 GB pen drives. Two 16 GB pen drives are defective, and four 32 GB pen drives are defective. If a pen drive is picked at random, what is the probability that it is a 16 GB pen drive or defective?

Answers

Answer 1

Therefore , the solution to the given problem of probability comes out to be P =0.6.

How are probabilities determined?

Probability theory, a subfield of mathematics, calculates the likelihood that an event will occur or that a statement is true. The probability of an event is a number between 0 and 1, where 1 denotes certainty and around 0 denotes how probable the event is to occur. A likelihood is a numerical representation of the likelihood that a particular event will occur. Probabilities may alternatively be stated as percentages with a range of 0% to 100% or as a number between 0 and 1. the percentage of events over a wide range of comparably likely outcomes that happen in comparison to all other conceivable outcomes.

Here,

Given :

Twelve 16 GB and 18 32 GB pen drives are packaged together in a box.

To find the probability of 16gb pen drive is defective:

Thus,

Total pendrive = 30

Event = 16gb pen drive or defective:

The probability of it is 16gb pendrive = 12/30 = 0.4

The probability of it is defective pendrive = 6/30 = 0.2

thus,

total probability (16gb pen drive or defective) = 0.4 +0.2 =0.6

Therefore , the solution to the given problem of probability comes out to be P =0.6.

Answer:

Step-by-step explanation:

58÷1.095= 53 is the answer

Answer:

5.03196347032

Step-by-step explanation:

We do:

.095x+x=58

1.095x=58

x=52.96

52.96 is a approximation and when you do the math and see what 9.5 of 52.96 plus 52.96 is you get 57.9912 which is super close to 8 The exact answer is x = 5.03196347032

If a varies directly as the cube root of b and if a=3 and b=64.find the formula connecting the variables hence find b when a=15/4

Answers

Answer:

b = 125

Step-by-step explanation:

Given a varies directly as [tex]\sqrt[3]{b}[/tex] then the equation relating them is

a = k[tex]\sqrt[3]{b}[/tex] ← k is the constant of variation

To find k use the condition a = 3 , b = 64 , then

3 = k[tex]\sqrt[3]{64}[/tex] = 4k ( divide both sides by 4 )

[tex]\frac{3}{4}[/tex] = k

a = [tex]\frac{3}{4}[/tex] [tex]\sqrt[3]{b}[/tex] ← equation of variation

When a = [tex]\frac{15}{4}[/tex] , then

[tex]\frac{15}{4}[/tex] = [tex]\frac{3}{4}[/tex] [tex]\sqrt[3]{b}[/tex] ( multiply both sides by 4 to clear the fractions )

15 = 3[tex]\sqrt[3]{b}[/tex] ( divide both sides by 3 )

5 = [tex]\sqrt[3]{b}[/tex] , then

b = 5³ = 125

What is the volume of the prism given below?

A. 280 units3
B. 480 units 3
C. 840 units 3
D. 420 units3

Answers

AnswerAnswer:

420

Step-by-step explanation:

The volume of the prism is 840 units³ which is correct option (C).

What is volume of prism?

The volume of the prism is defined as the measure of the space occupied within a prism . The prism is a three-dimensional shape that has base area, and height. The volume of a prism is equal to the product of base area and height of a prism.

The volume of the prism= B×H

Where, B is base area of prism, and H is height of prism.

Given that,

Length of prism (L) = 12 centimeters

Width of prism(W) = 14 centimeters

Base area (rectangle) of prism = L × W

Base area (rectangle) of prism = 12 × 14

Base area (rectangle) of prism = 168 units²

Height of prism(H) = 5 units

The volume of the prism = B × H

Substitute the values in above formula,

The volume of the prism = 168×5

The volume of the prism = 840 units³

Hence, the volume of the prism is 840 units³.

(a) Are there any outliers in the data set? Justify your answer numerically

Answers

Step-by-step explanation:

First we must calculate the interquartile range (IQR), using this equation:

[tex]IQR = Q_{3} - Q_{1}[/tex]

Based on the information provided we fill in:

[tex]IQR = 58 - 45[/tex]

[tex]IQR = 13[/tex]

In order to find what the range for the data set is we need to use the Interquartile Rule:

[tex]Q_{1}-1.5[/tex] × [tex]IQR\\[/tex]

[tex]Q_{3}+1.5[/tex] × [tex]IQR\\[/tex]

[tex]1.5[/tex] × [tex]13 = 19.5[/tex]

Now we plugin in:

[tex]45 - 19.5 = 25.5\\[/tex]

[tex]58 + 19.5 = 77.5[/tex]

Any number below 25.5 is a possible outlier and any number above 77.5 is a possible outlier.

Answer:

Based on the results of the calculations, 25 could be a possible outlier in the data set.
