Answer:

option B

Step-by-step explanation:

Given :

$y = \frac{2}{3}x + 3\\\\y = \frac{5}{2}x + \frac{7}{2}\\\\$

Step 1 : simplify the equation :

$3y = 2x + 9\\\\2y = 5x + 7\\$

Step 2: Arrange the terms :

$2x - 3y = - 9\\\\5x -2 y = -7$

Step 3 : Solve for x and y :

2x - 3y = - 9 ------ ( 1 )

5x - 2y = - 7 --------- ( 2 )

_____________________

( 1 ) x 5 => 10x - 15y = - 45 ---------- (3 )

( 2) x 2 => 10x - 4y = - 14 ----------- (4 )

_______________________

( 3 ) - ( 4 ) => 0x - 11y = - 31

- 11 y = - 31

$y = \frac{31}{11}$

Substitute y in ( 1 ) :

2x - 3y = - 9

$2x - 3 (\frac{31}{11}) = - 9\\\\2x = -9 + 3(\frac{31}{11})\\\\2x = - 9 + \frac{93}{11}\\\\2x = \frac{-99 + 93}{11} \\\\2x = \frac{-6}{11} \\\\x = \frac{-6}{2 \times 11} = -\frac{3}{11}$

Therefore the solution to the sytem is $( - \frac{3}{11} , \frac{31}{11})$

The solution of the system of equation is a point which lies

on the both the lines.

Option A : False , It says the solution lies above one of the given line.

But the solution of the system of equation always lies on

both the line.

Option B : True , says the solution is a point on the coordinate plane.

Option C : False, because if the solution is on the x-axis , then

the y coordinate in the solution would be zero.

But it is not zero.

Option D : False , the solution is the point where both the lines intersect.

D is correct!

bagirrra123 [75]

Answer:

The bias most likely to be present in the survey results is;

Option A; This is question wording bias because the survey question attempts to influence subjects’ responses.

Step-by-step explanation:

A bias occurs when a group or outcome is intentionally or unintentionally favored over another group or outcome in the a general population.

There are two main types which are;

- Selection bias which includes; Non - response bias, non representative sample and voluntary bias

- Response Bias which includes wording bias, extreme responses, neutral responses e.t.c

Let's look at each of the options;

Option A; This is correct because what occurred is that the concerned student by telling the adults adverse effect of plastics in our environment, he is indirectly influencing the adults to have a bad mindset about the plastics. He is leading them on by the way he phrased the word to ask the question.

Option B; This is not the reason why it is a response bias. The reason it is a response bias is because he led them on with his wording of the question.

Option C; Like said in Option A & B above, the scenario is that of a response bias since they are giving answers.

Option D; Voluntary response bias is a type of non-response bias and so it is not correct here
