Answer:
the population in 2015 is 8201.0695
Step-by-step explanation:
Given that
There is a population of the 50 timber wolves
And, the exponential function given is
p(t) = 50 × e^(0.85 × t)
Here t denotes the time period i.e.
= 2015 - 2009
= 6
So,
= 50 × e^(0.85 × 6)
= 8201.095
Hence, the population in 2015 is 8201.0695
You move to the left since you are multiplying
51 blue fish.
If there is 34 to 50 blue to red fish in tank A. Then tank B is 51 to 75. Because 75 is 1.5 times larger than 50 you have to multiply 34 by 1.5 to get 51.
The correct answer for this question is this one: "C).a unique,acute triangle"
The statement that best describes a triangle with side lengths of 6 inches 8 inches and 9 inches is that it is <u>a unique,acute triangle</u><span>
Hope this helps answer your question and have a nice day ahead.

Answer:
Answer = a. 2
Degree of freedom df = (r – 1)(c – 1) = (2 – 1)(3 – 1) = (1)(2) = 1 x 2 = 2
Step-by-step explanation:
The degree of freedom of a one-dimensional chi-square statistic is df = n– 1, where ‘n’ is the number of categories or levels of the independent variable. But in this case, we are to analyze a two-way contingency table. This Chi-square test of independence uses a contingency table format. It is also referred to as a contingency table test. A (row X column) contingency table shows the observed frequencies for two categorical variables ( in the is case: TV shows and Gender) arranged in ‘r’ rows and ‘c’ columns. The sum of the observed frequencies is ‘n’, the sample size, that is, the row and column totals adds up to form a grand total ‘n’ which is the sample size. Since the rows and columns have been classified into mutually exclusive categories where the three TV shows will serve as the column heads and the male and female classification will serve as the rows, the degree of freedom for the test will be to multiply the individual degree of freedom of both row (r-1) and column (c-1) numbers in the (row X column) contingency table format for the test. Thus the degrees of freedom df = (r – 1)(c – 1), where r = number of rows(Male/Female) and c = number of columns (TV shows) .
Now, the gender here is 2 and the TV shows are 3
So, r = 2 and C = 3
Degree of freedom df = (r – 1)(c – 1) = (2 – 1)(3 – 1) = (1)(2) = 1 x 2 = 2
