Airport administrators take a sample of airline baggage and record the number of bags that weigh more than 75 pounds. What are t

kherson [118]

In this situation, the cases are the bags or each piece of baggage.

In statistics, the word case is used to refer to the individual from which data is collected. For example, in a study about students' performance, the cases are each of the students.

<h3>What is the case in this situation?</h3>

Considering the administrators will need to weight and record each bag, the cases are each piece of baggage.

Note: This question is incomplete; here are the missing options:

A. Number of bags weighing more than 75 pounds.

B. Average weight of the bags.

C. Each piece of baggage.

D. The airport administrators.

A system of linear equations with more equations than unknowns is sometimes called an overdetermined system. Can such a system b

shepuryov [24]

Answer:

A. Yes, overdetermined systems can be consistent.

As, the system of equations below is consistent because it has a solution

$x_{1}=2$ , $x_{2}=4$ , $x_{1}+x_{2}=6$ .

Step-by-step explanation:

We have,

'Over-determined system is a system of linear equations, in which there are more equations than unknowns'.

For e.g. Let us consider the system,

2x - 3y = 1

3x - 2y = 4

x - y = 1

Plotting these equations, we see from the graph below that,

The only intersection point is (2,1). Thus, x= 2 and y= 1 is the solution of this system.

Thus, over-determined system can be consistent.

According to the options,

Option C is not correct as,

$x_{1}=2$ , $x_{2}=4$ implies $x_{1}+x_{2}=2+4=6\neq 8$ .

Hence, option A is correct.

Solve the system of equations below using a matrix equation.

andreev551 [17]

Answer is b. ( -1, -5)

Answer is b. (-1, -5)

Step by step

Substitute the x and y values into both equations to find equality

Answer b. Makes both equations equal

2x + y = -7

2(-1) + (-5) = -7

-2 -5 = -7

-7 = -7
it equals now let’s do the 2nd one

x - y = 4

-1 -(-5) = 4

4 = 4

This one equals too. I did the math on the other three answers and they did not equal.
