Dogs are inbred for such desirable characteristics as blue eye color, but an unfortunate by-product of such inbreeding can be th

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.

Determine if DE is parallel to AC. Show all your work!!!

skelet666 [1.2K]

Answer:

Step-by-step explanation:

We will prove the converse of the postulate,

"If a line parallel to one side of a triangle and it intersects other two sides of the triangle, then the line will divide both the sides in the same ratio"

Segment DE intersects AB and BC at D and E respectively,

Ratio of the segments of two sides,

$\frac{AD}{DB}=\frac{CE}{EB}$

$\frac{22.5}{15}=\frac{24}{40-24}$

1.5 = 1.5

True.

Therefore, lines AC and DE are parallel.

Jose is working two summer jobs, making $10 per hour washing cars and $9 per hour walking dogs. Last week Jose worked a total of

Setler [38]

Answer:

x+y =13

10x + 9y =122

Step-by-step explanation:

Hi, to answer this question we have to write a system of equations:

The sum of the hours he worked washing cars (x) and the hours he worked walking dogs(y) will be equal to the total hours worked (13)

x+y =13

For the second equation the product of the number of hours he worked washing cars(x) and the price per hour ($10) plus the product of the number of hours he worked walking dogs (y) and the price per hour ($9) will be equal to the total amount earned (122)-

10x + 9y =122

So, the system of equations is:

x+y =13
10x + 9y =122

Where:

x: number of hours Jose worked washing cars

y: number of hours Jose worked walking dogs
