I like to use the equation n(r)^t, where n is the first term, r is the rate, and t is the time.

In this case 523 is n, or the first term. Since this study started in 1990, the answer is B.

Hope this helps!

6.11 Assume that an r of .80 describes the relationship between daily food intake, measured in ounces, and body weight, measured
Sloan [31]

Answer:

The coefficient of correlation does not change.

Step-by-step explanation:

We are given the following in the question:

The daily intake food is measured in ounces.

The body weight is measured in pounds.

Correlation between food intake and body weight = 0.80

Properties of correlation:

  • Correlation is a technique that help us to find or define a relationship between two variables.
  • It is a measure of linear relationship between two quantities.
  • The correlation between two variables is not effected by the units of the variable.
  • Even if the variable of the explanatory variable or the response variable changes, the correlation does not not change and remains same.

Conclusion:

A shift in units from ounces to grams and from pounds to kilogram does not change the value of coefficient of correlation.

The total number of alphabets are 26.

The total number of vowels are 5.

Th repetition is allowed.

The possible outocme for all to be vowels are,

PO=5^4PO=625

The total outcome is,
