A) 20 households are randomly selected from the town; 8 own a dog
why: when conducting a survey to determine approximations in a population, it’s best to eliminate any and all biases for best results. Households who live near a park or have their own front yards will skew results as the rest of the population may not have access to those things, thus are more likely to not have a dog.
b) 8/20= 0.40
600*0.40= 240

Answer:
what are the #
Step-by-step explanation:??
He needs 160 5-star reviews in a role. We can write a function to solve this problem. His current total stars is 4.4*160=704. Suppose he needs x more 5-star reviews, then his total stars will be 704+5x. 160+x is the new number of reviews, and the new average will be 4.7, so 4.7*(160+x)=704+5x. The solution is 160. Besides, if you want to get the answer really fast, you can see that 4.7 is right in the middle of 4.4 and 5, so you can immediately guess that the number of new 5-star reviews should be equal to the number of current reviews.
