Subtitute 2x+y=7 and 3x-y=8
iogann1982 [59]

Answer:

x = 3 , y = 1

Step-by-step explanation:

2x + y = 7

3x + y = 8

solution

2x + y = 7-----------(1)

3x - y = 8------------(2)

from equation 1

2x + y = 7

y = 7 - 2x-------------(3)

substitute equation 3 into equation 2

3x - y = 8

3x - (7 - 2x) = 8

3x - 7 + 2x = 8

3x + 2x = 8 + 7

5x = 15

divide through by the coefficient of x

5x/5 = 15/5

x = 3

to find y

substitute x into equation 1

2x + y = 7

2(3) + y = 7

6 + y = 7

y = 7 - 6

y = 1

Agata [3.3K]

Answer:

<h2>Option 2 is the right answer.</h2>

Step-by-step explanation:

We need to check if the two characteristics, <u>having blue eyes and being deaf are independent of each other or not</u>.

The above two characteristics will be independent if [Probability of being deaf with blue eyes] = {Probability of being deaf } {Probability of having blue eyes}

Now, the probability of having blue eyes is \frac{31}{100}.

The probability that the Dalmatians will be deaf is \frac{38}{100}.

The probability of being deaf with blue eyes is \frac{31}{100} \times\frac{42}{100}.

Since, 38 is not equals to 42, the two characteristics are not independent.
