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

e emergence of characteristics such as deafness. A 1992 study of Dalmatians (by Strain and others, as reported in The Dalmatians Dilemma) found the following: (i) 31% of all Dalmatians have blue eyes. (ii) 38% of all Dalmatians are deaf. (iii) If a Dalmatian has blue eyes, there is a 42% chance that it is deaf. Based on the results of this study is "having blue eyes" independent of "being deaf"(a) No, since .31 * .38 is not equal to .42.(b) No, since .38 is not equal to .42.(c) No, since .31 is not equal to .42.(d) Yes, since .31 * .38 is not equal to .42.(e) Yes, since .38 is not equal to .42.

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.

Points A and B have coordinates (8, 3) and (p, q) respectively. The equation of the perpendicular
DaniilM [7]

Answer:

p = -4, q = -3

Step-by-step explanation:

y = -2x +4  ... (1)   perpendicular bisector of AB, slope = -2

slope of AB = 1/2

Line AB pass (8,3): (y-3) / (x-8) = 1/2

AB equation: y-3 = 1/2(x-8)      y = 1/2x - 1  ... (2)

(2)-(1): 5/2 x = 5      x = 2

y = 0       (2,0) intercept of bisector and AB, it is midpoint of A (8,3) and (p,q)

(8+p)/2 = 2

<u>p = -4</u>

(3+q)/2 = 0

<u>q = -3</u>

A home has a living room that is 14 ft. wide, 22 ft. long, and a height of 9ft. Bob needs to paint
aleksandrvk [35]

Answer:

Step-by-step explanation:

Let's find the volume of the room in ft³ and that will give

14×22×9=2772ft³

There are deductions. Hence we subtract them from this value

3×5=15, but there are two, hence 15×2=30ft²

And 4×7=28ft²

Hence 2772-(30+28)=2714

Dividing this value by 320 gives

8.4(to 2s.f)

A The number of tropical fish that an aquarium can hold depends on the volume of the fish tank. The interior dimensions of a fis
Delicious77 [7]

Answer:

7

Step-by-step explanation:

We need to first of all find the volume of the fish tank. The most probable shape the ship tank can have is that of a cuboid.

The volume of a cuboid is l * b * h

And this is equals 30cm * 70cm * 90cm = 189,000 cubic centimeters

The number of fish the tank can contain can be obtained by dividing the volume by the volume occupied by a single fish.

This is 189,000/27000 = 7
