120 is good engough if you dont kn o
2 5/7 as a decimal is approximately 2.70
We know that the ones place will be a two. That doesn’t change when you convert. Next you need to divide 100 by 7, which equals 14. Then you need to do 14 times 5, which equals 70. So, now you know the values after the decimal point (.70). Combine that with the whole number 2 to get 2.70.
Answer:
a. A two-sample z-test for a difference in sample proportions
Step-by-step explanation:
We are told that there are two supermarkets in the research named X and Y.
That a random number of shoppers were selected in each supermarket.
Thus means we have two different sample proportion.. Since a different number of people were randomly selected from each supermarket and a different number of people purchased the product.
Thus, we will have 2 sample proportions one for supermarket X and the other for supermarket Y.
In addition, the position of the product was different in both supermarkets.
Thus, we can say that this is a 2 sample Z-test for difference in their sample proportion.
Answer:
t = 3
Step-by-step explanation:
- 16t^2 +144 you can rewriting in this form 144 -16t^2 = (12 -4t)(12+4t)
12-4t=0
12 =4t divide both sides by 4
t=3
hope helped add me as friend
