Interest centers around the life of an electronic component. Let A be the event that the component fails a particular test and B be the event that the component displays strain but does not actually fail. Event A occurs with probability 0.39​​, and event B occurs with probability 0.24. A) What is the probability that the component does not fail the​ test?
B) What is the probability that a 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?

Answers

Answer 1
Answer:

Answer: a. 0.61

b. 0.37

c. 0.63

Step-by-step explanation:

From the question,

P(A) = 0.39 and P(B) = 0.24

P(success) + P( failure) = 1

A) What is the probability that the component does not fail the​ test?

Since A is the event that the component fails a particular test, the probability that the component does not fail the​ test will be P(success). This will be:

= 1 - P(A)

= 1 - 0.39

= 0.61

B) What is the probability that a component works perfectly well (i.e., neither displays strain nor fails the test)?

This will be the probability that the component does not fail the​ test minus the event that the component displays strain but does not actually fail. This will be:

= [1 - P(A)] - P(B)

= 0.61 - 0.24

= 0.37

C) What is the probability that the component either fails or shows strain in the test?

This will simply be:

= 1 - P(probability that a component works perfectly well)

= 1 - 0.37

= 0.63

Solve for M in the formula S= C+M. A. M= S+ C
B. M= S - C
C. M= SC
D. M= s/c

Answers

Final answer:

To solve for M in the formula S = C + M, subtract C from both sides of the equation.

Explanation:

To solve for M in the formula S = C + M, we need to isolate the variable M on one side of the equation. To do this, we can subtract C from both sides of the equation:

S - C = C + M - C

S - C = M

Therefore, the correct answer is B. M = S - C.

Identify the independent and dependent variables in the following hypothesis: "People who exercise regularly are more likely to have normal or below normal weight." Exercise is the ________ variable and weight is the _________ variable

Answers

Exercise will be the independent variable while weight will be the dependent variable.

Nowadays most of us do exercise in order to burn extra calories, that in turn, reduce the weight of a person. Some exercises even increase the weight of a person.

What if we do not do the exercise?

Our weight will increase or will remain constant. In a few cases, it will decrease the weight.

So it is clear that weight depends on many factors. one of those factors is exercise.

So weight is the dependent variable while exercise will be an independent variable.

Therefore, exercise will be the independent variable while weight will be the dependent variable.

Answer:

Independent

dependent

Step-by-step explanation:

The scenario illustrates that the weight for people who exercises regularly tends is normal or below normal. It means that the weight of a person depends on how much a person exercises i.e. if person exercises more the weight is reduced and if not then weight will be gained. Thus, exercise is the independent variable while weight is dependent variable.

An train station has determined that the relationship between the number of passengers on a train and the total weight of luggage stored in the baggage compartment can be estimated by the least squares regression equation y=103+30x. Predict the weight of luggage for a flight with 86 passengers.

Answers

Answer:

2683

Step-by-step explanation:

Using the linear regression equation that predict the relationship between the weight of the luggage and the total number of passenger y = 103 + 30x, we can plug in the number of passenger x = 86 to predict the weight of the luggage on a flight:

y = 103 + 30*86 =  2683
