Hailey records the weights of five dogs of one breed and five dogs of another breed.What can she infer about the weights of Breed 1 dogs and Breed 2 dogs?

Breed 1 dogs and Breed 2 dogs have similar weight distributions.

Breed 1 dogs and Breed 2 dogs have no overlap in their weight distributions.

She infer about the weights of Breed 1 dogs and Breed 2 dogs is;

Breed 1 dogs and Breed 2 dogs have no overlap in their weight distributions.

Hence, Option B is the correct answer.

What is set?

A set is a collection of well defined elements or objects. A set is denoted by a capital letter symbol, and the cardinal number of a set, enclosed in a curly bracket, denotes the number of elements in a finite set.

Given that;

Breed 1 (38, 45, 49, 51, 52)

Breed 2 (35, 36, 40, 44, 50)

Now, comparing them is simpler. You can tell right immediately that they don't quite match and that they do overlap. so C or D cannot be the case.

As they are over a comparable range, I would say B, although the spread is different for both.

Which of these percentages is closest in value to 7/9 ?
a. 76%
b. 77%
c. 78%
d. 79%

Answers

$(7)/(9) = 0.777777777777777...$

To get a percentage, you need to first round the decimal to the hundreths place. Whenever you have a number greater than 5, you round up.
Therefore, you can round it to 0.78.
Now to get the percentage you multiply it by 100.

$0.78*100 = 78$

This shows your answer is (c) 78%.
