The Paleo diet allows only for foods that humans typically consumed over the last 2.5 million years, excluding those agriculture

-type foods that arose during the last 10,000 years or so. Researchers randomly divided 500 volunteers into two equal-sized groups. One group spent 6 months on the Paleo diet. The other group received a pamphlet about controlling portion sizes. At the beginning of the study, the difference in mean weight between the two groups was approximately equal to 0. After the study, the Paleo group had lost on average of 7 pounds with a standard deviation of 20 pounds while the control group had lost on average of 5 pounds with a standard deviation of 12 pounds. (a) Create a 95% confidence interval for the difference in mean weight loss for the two groups (Paleo minus Control). For degrees of freedom, use Min(N1-1,N2-1), and for the corresponding t* use either Table D (with degrees of freedom closest to the exact value) or Excel. Give your answer to 3 decimal places

Determine whetherfis a function from the set of all bitstrings to the set of integers if
ipn [44]

Answer:

a) Not a function

b) It is a function

c) It is a function

Step-by-step explanation:

a) f(S) is not completly well defined, becuase if the bistring has multiple zeros, you need to pick one and there is not specified method in how you would do so. Another reason for which f is not well defined as a function is that for a bistring with only 1's, f is not defined because there is no zero.

b) This is a function. f(S) returns a concrete and unique integer number for each bistring S. If the bistring has only zeros, the f(S) = 0.

c) This is well defined as a function. It compensates for the failures of the first definition:

- If multiple zeros appears in S, you pick the first one, so there is one possible value for f(S)

-If no zeros appear, f is still well defined because it takes the value 0, as specified in the definition.

Completely factor the polynomial below.
Blizzard [7]
The first step for solving this expression is to write 6q as a difference.
8q² + 10q - 4q - 5
Now factor out 2q from the first part of the expression (8q² + 10q).
2q × (4q + 5) - 4q - 5
Extract the negative sign from the second part of the expression (-4q - 5).
2q × (4q + 5) - (4q + 5)
Lastly,, factor out 4q + 5 from the expression to find your final answer.
(4q + 5) × (2q - 1) 
This means that the correct answer to your question is (4q + 5) × (2q - 1),, or option D.
Let me know if you have any further questions.

The value of y is directly proportional to the value of x. If y =35 when x = 140, what is the value of y when x =70?
torisob [31]
17.5 because 140 divided by 35 is 17.5 and so is 70 divided by 35.
