37. The students at Norton School were asked to name their favorite type of pet. Of the 430 students surveyed, 258 said that their favorite type of per
was a dog. Suppose that only 100 students were surveyed, with similar results, about how many students would say that a dog is their favorite
type of pet?

60 students

Step-by-step explanation:

So, in the first situation 430 students were surveyed and 258 said that their favourite pet was a dog. The second situation is 100 students and x said that their favourite pet was a dog. We are solving x.

430=258

100= x

Cross multiply

So that is

430 x X= 100x258

430x=25800

Divide both sides by 430

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

the number 100 represents the number of trials in the experiment.

49/100 represents the experimental probability of the coin landing heads up.
