Ben says this system of equations has one solution. Is he​ correct? Explain. Choose the correct answer below. A. Ben is correct.

Since the equations have the same​ slope, the system has exactly one solution. B. Ben is correct. Since the equations have the same slope and different​ y-intercepts, the system has exactly one solution. C. Ben is incorrect. Since the equations have the same slope and different​ y-intercepts, the system has no solution. D. Ben is incorrect. Since the equations have the same​ slope, the system has infinitely many solutions.

Answer:

C. Ben is incorrect. Since the equations have the same slope and different y-intercepts, the system has no solution

Step-by-step explanation:

From the given options the parameters of the equations are;

The slope of the equations are the same

The y-intercept of the equations are different

Therefore, the lines of the two equations ae parallel and there are no points of intersection of the two equations and therefore no solutions

The best correct option is therefore option C.;

C. Ben is incorrect. Since the equations have the same slope and different y-intercepts, the system has no solution.

A manufacturer of tablets receives its LED screens from three different suppliers, 45% from supplier B1, 30% from supplier B2, a
Shalnov [3]

Answer:

a) 0.83 = 83% probability that a LED screen will meet specifications.

b) 0.2892 = 28.92% probability that a LED screen that meets specifications was sent by the second supplier.

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

P(B|A) = \frac{P(A \cap B)}{P(A)}

In which

P(B|A) is the probability of event B happening, given that A happened.

P(A \cap B) is the probability of both A and B happening.

P(A) is the probability of A happening.

45% from supplier B1, 30% from supplier B2, and the rest from supplier B3.

So 100 - (45 + 30) = 100 - 75 = 25% from supplier B3.

a) Find the probability that a LED screen will meet specifications.

95% of 45%(supplier B1)

80% of 30%(supplier B2)

65% of 25%(supplier B3). So

p = 0.95*0.45 + 0.8*0.3 + 0.65*0.25 = 0.83

0.83 = 83% probability that a LED screen will meet specifications.

b) Calculate the probability that a LED screen that meets specifications was sent by the second supplier.

Conditional probability.

Event A: Meets specifications.

Event B: Sent by second supplier.

0.83 = 83% probability that a LED screen will meet specifications.

This means that P(A) = 0.83

Meets specifications and is sent by the second supplier.

80% of 30%, so

P(A \cap B) = 0.8*0.3 = 0.24

Probability:

P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.24}{0.83} = 0.2892

0.2892 = 28.92% probability that a LED screen that meets specifications was sent by the second supplier.

Taylor plans to borrow $4500 from the bank to purchase a used vehicle if he borrows the money by the rate of 4% simple interest
Vadim26 [7]

Answer:

$360

Step-by-step explanation:

Given

Amount borrowed P = $4500 (principal)

Time T = 2 years

Rate R = 4

Simple interest formula is expressed as;

SI = PRT/100

Substitute the given parameters into the formula

SI = 4500×2×4/100

SI = 45×2×4

SI = 45×8

SI = $360

The amount of interest he will have to pay is $360
