Which of the statements below are true? Select all that apply. A correlation of r = .92 indicates a strong, positive correlation

. Correlation must be between 0 and 1. A correlation of r = -.17 indicates a strong, negative correlation. A correlation of r = .01 means there is no significant correlation. Correlation must be between -1 and 1. Correlation is a numeric measure of the strength and the direction between two categorical variables.

Answer with explanation:

Correlation Coefficient (r) ,measures the relation between two variables written in the form of ordered pair.

→If ordered pair (x,y) represents two variables , correlated with each other

that is with increase in x, y also increases, or vice versa ,then r would be positive.

And if , with increase in x, y decreases or vice versa, then r will be negative.

→ -1 ≤ r ≤1.

The Correct statements are

1. →A correlation of r = .92 indicates a strong, positive correlation.

4.→A correlation of r = .01 means there is no significant correlation.

5.→ Correlation must be between -1 and 1.

6.→Correlation is a numeric measure of the strength and the direction between two categorical variables.

Answer:

x = tan⁻¹(⅘)

Step-by-step explanation:

We can solve for x by using trigonometric ratios (sin, cos, and tan)

We need to apply the appropriate ratio that uses the two sides 8 and 10 from the perspective of x. See attached image for information about ratios. (Source: Math is Fun)

The tangent ratio is opposite divided by adjacent. It will relate x to the two sides. So we would write

tan(x) = ⁸⁄₁₀

Then we simplify and move the tan to the other side by multiplying both sides by the inverse of tan (since you cannot divide by tan)

tan(x) = ⅘

x = tan⁻¹(⅘)

Then we can use a calculator to evaluate x

If you want to find y, now that you have two angles of the triangle, you can find the sum of 90 + x and subtract that from 180 (since all angles of a triangle add up to 180) to find y.

Vilka [71]

Answer:

   24 birds

Step-by-step explanation:

Let b represent the number of birds at the shelter on Wednesday. Then the cost of care for the 41 animals is ...

  5b +7.5(41 -b) = 247.50

  -2.5b +307.50 = 247.50 . . . . . simplify

  -2.5b = -60 . . . . . . . . . . . . . . . . subtract 307.50

  b = 24 . . . . . . . . . divide by -2.5

The number of birds at the shelter on Wednesday was 24.
