Given the following information, find the probability that a randomly selected dog will be a golden retriever or a poodle. Numbe
Flauer [41]

Answer: a) 39.5%

Step-by-step explanation:

<em>For random selections, we assume that all the dogs have the same probability of being selected.</em>

In this case, the probability will be equal to the number of golden retrievers divided the total number of dogs.

We have 58 golden retrievers, and the total number of dogs is:

31 + 58 +20 + 38 = 147

Then the probability is:

P = 58/147 = 0.395

If we multiply it by 100%, we obtain the percentage form:

0.395*100% = 39.5%

So the correct option is a.

What is the domain in interval notation?
Free_Kalibri [48]

Hello!


Interval notation is written using brackets or parentheses. Brackets mean that the value of the corresponding side is equal to the function. Parentheses are the opposite of brackets in this case, and it is not part of the equation.


I will post the graph of this equation below.


Therefore, the domain of this equation in interval notation is (-∞, 6/7).


Note that it is parentheses not brackets. The graph does not go past 6/7, and infinity is not a number, it is a concept.

Image point B (4,-8) was transformed using the translation (x-2,y+3) what were the coordinates of B?
PilotLPTM [1.2K]
The coordinates of the image point are given to be B(4, -8). We are to find the coordinates of pre-image that is the coordinates before the translation.

The translation made was (x-2, y+3) 

This means, the x coordinate was moved 2 units to left and y coordinate was moved 3 units above. 

So, the coordinates of original point will be, 2 units to right of B and 3 units down of B.

So the coordinates will be (6, -11)
