Answer:
A prospective study
Step-by-step explanation:
A prospective study watches for outcomes, such as the development of a disease (in this case cancer). It also usually involves taking a group of subjects and watching them over a long period of time. The outcome of interest should be common between them (whether certain smoking habits lead to the development of cancer in British doctors).
Answer: 9.
Step-by-step explanation:
8 5/6 is a mixed number with a whole number and a fraction. We want to round to the nearest whole number without the fraction.
First, we convert the mixed fraction to an improper fraction or fraction like this:
((8 x 6)+5)/6 = 53/6
Then, we divide the numerator by the denominator from the previous step:
53/6 = 8.83
Now we have one decimal number. Round using the following rules:
If the number to the right of the decimal point is .5 or higher, then add 1 to the left of the decimal point.
If the number to the right of the decimal point is less than .5, then leave the number to the left of the decimal point as is.
.83 is .5 or higher. Thus, we add 1 to the left of the decimal point. 8 5/6 rounded to the nearest whole number is therefore the answer will be 9.
Answer:
(4y + 1)(2y + 1) -- Unfortunately I can't help with the grid part
Step-by-step explanation:
Multiply the a and c term (8 * 1) to get 8. Think of what factors of 8 would add up to your b term (6), which would be 4 and 2. Rewrite your equation as 8y^2 + 4y + 2y + 1 and consider one half at a time and factor them individually. For the left, that'd be 4y(2y + 1), and for the right, you can't factor anything so it's just 1(2y + 1). Check that the things inside the parentheses are the same, which they are, and add the things you factored out and multiply that by the part in the parentheses for (4y + 1)(2y + 1).
