B Yes, this is a valid inference because she took a random sample of the neighborhood
C No, this is not a valid inference because she only asked 25 families
D No, this is not a valid inference because she did not take a random sample of the neighborhood
Answer
Yes, this is a valid inference because she took a random sample of the neighborhood.
Step-by-step explanation:
As we can see that Sue's survey was non biased and completely random.
She found that 18% of the families would volunteer to help at the shelter. She claims that 18% of the neighborhood families would be expected to to help at the animal shelter.
So, yes, this is a valid inference because she took a random sample of the neighborhood.
Answer:
the answer is B Yes, this is a valid inference because she took a random sample of the neighborhood.
Step-by-step explanation:
The organic farmer will have 13/36 part of the land for planting potatoes.
A fraction is written in the form of p/q, where q ≠ 0.
Fractions are of two types they are proper fractions in which the numerator is smaller than the denominator and improper fractions where the numerator is greater than the denominator.
Assuming the total land to be 1.
∴ The remaining land after planting tomatoes is (1 - 5/9) = 4/9.
The remaining land after planting green beans is (4/9 - 1/12) = (16 - 3)/36.
= 13/36 and it is the remaining land he can plant potatoes.
