Answer: -0.83

Step-by-step explanation:

A correlation coefficient(r) is used to determine the strength and direction of the relationship between two variables.

-1 ≤ r ≤1

For downward trend r is negative.

For strong correlation r should be closer to 1 or -1.

From the given correlation coefficients -0.83 is both negative and closer to -1.

Hence, a correlation coefficient represents the strongest downward trend in a data set = -0.83

Please help i need this done

3x - 2 = x + 1
2x = 3
x = 3/2
x = 1.5

3x - 2 = 3(1.5) - 2 = 2.5
or
x + 1 = 1.5 + 1 = 2.5

P = 4(2.5) = 10

perimeter of square is 10 cm so side of square = 2.5cm

Which of these algebraic expressions matches the verbal description "k cubed plus 7"? a. k3 +7 b. (k + 7) C. k + 73 d. 3k + 7 e

steposvetlana [31]

Answer:

Step-by-step explanation:

Just as squared has an exponent of 2, cubed has an exponent of 3.

Therefore, k is seen as $K^{3}$ (or K^3 if that is too small to see)

Another keyword is "plus" as this indicates addition which has a symbol of +

So in this case, your answer would be A) K^3 + 7
