2.65 Consider the situation of Exercise 2.64. Let A be the event that the component fails a particular test and B be the event t

hat the component displays strain but does not actually fail. Event A occurs with probability 0.20, and event B occurs with probability 0.35. (a) What is the probability that the component does not fail the test? (b) What is the probability that the component works perfectly well (i.e., neither displays strain nor fails the test)? (c) What is the probability that the component either fails or shows strain in the test?

Answer:

a) 0.80

b) 0.45

c) 0.55

Step-by-step explanation:

Given P(A) = 0.20 and P(B) = 0.35

Applying probability of success and failure; P(success) + P( failure) = 1

a) probability that the component does not fail the test = The component does not fail a particular test [P(success)] = 1 - P(A)

= 1 - 0.20 = 0.80

b) probability that the component works perfectly well

= P( the component works perfectly well) - P(component shows strain but does not fail test)

= 0.80 - 0.35 = 0.45

c) probability that the component either fails or shows strain in the test = 1 - P(the component works perfectly well)

= 1 - 0.45 = 0.55

uranmaximum [27]
The best way to randomly choose the 100 families would be to allow a random number generator to come up with 100 families within a 50 radius of the amusement park.

Using this method would ensure that it is more randomised & not limited to people who come at a specific time or are in a specific area as well as it not be affected by subconscious bias of people when selecting people to survey.

1.04 / 2 = 0.52

2.52 / 4 = 0.63    best 1

4.32 / 8 = 0.54

9.12 / 16 = 0.57    best 2

if base on the best deal 1 - 0.63

(0.63 - 0.57) / 0.63 = 0.0952  (≈ 0.09 i.e 9%)

a)                      

b) number of flowers.  

c) 2830              

Step-by-step explanation:

We are given the following in the question:

The number of flowers bloomed is given by the function:

 

where s is the s is the number of seeds she planted.

The number of seeds planted per week is given by

where w represents the number of weeks.

a)  composite function that represents how many flowers Lily can expect to bloom over a certain number of weeks.

The composite function can be written as:

where f(w) gives the number of flowers that bloomed in w weeks.

b)  units of measurement for the composite function

The composite functions gives the number of flower that will bloom in w weeks. Thus, the unit of measurement is number of flowers.

c) Number of flowers in 35 weeks.

We put w = 35 in the composite function.

2830 flowers will bloom in 35 weeks.

A large restaurant is being sued for age discrimination because 15% of newly hired candidates are between the ages of 30 years a
Fudgin [204]

Answer:

See explanation below.

Step-by-step explanation:

Let's take P as the proportion of new candidates between 30 years and 50 years

A) The null and alternative hypotheses:

H0 : p = 0.5

H1: p < 0.5

b) Type I error, is an error whereby the null hypothesis, H0 is rejected although it is true. Here, the type I error will be to conclude that there was age discrimination in the hiring process, whereas it was fair and random.

ie, H0: p = 0.5, then H0 is rejected.

What do the symbols of mirrors and glass represent in this
luda_lava [24]

Question:

Read the excerpt from Julius Caesar, act 1, scene 2.

CASSIUS: ‘Tis just; And it is very much lamented, Brutus, That you have no such mirrors as will turn Your hidden worthiness into your eye, That you might see your shadow. I have heard 5 Where many of the best respect in Rome– Except immortal Caesar‐speaking of Brutus, And groaning underneath this age’s yoke, Have wished that noble Brutus had his eyes.

BRUTUS: Into what dangers would you lead me, Cassius, 10 That you would have me seek into myself For that which is not in me?  

CASSIUS: Therefore, good Brutus, be prepared to hear. And since you know you cannot see yourself So well as by reflection, I, your glass, 15 Will modestly discover to yourself That of yourself which you yet know not of.

Answer:

The correct choice is D)

Explanation:

Cassius speaks of Brutus as one who is unable to see or know his own value and presumes to help him therewith. He does this by pointing out that many of the well respected people in Rome wish that he were in Caesars shoes as King.

Cheers!
