The approximate value of the correlation coefficient for the given graph is 5.

To calculate the correlation coefficient, we first need to determine the equation of the line that passes through the points (0, 35) and (6, 5).

The formula for the equation of a straight line is y = mx + b, where "m" is the slope and "b" is the y-intercept.

Given two points (x₁, y₁) = (0, 35) and (x₂, y₂) = (6, 5), we can find the slope "m" as follows:

m = (y₂ - y₁) / (x₂ - x₁)

m = (5 - 35) / (6 - 0)

m = -30 / 6

m = -5

Now that we have the slope "m" as -5, we can find the y-intercept "b" by using one of the given points, say (0, 35):

y = mx + b

35 = -5(0) + b

35 = b

So, the equation of the line is y = -5x + 35.

Now, we can use this line to calculate the correlation coefficient "r" for the given graph.

The correlation coefficient "r" is given by the formula:

r = ∑((xᵢ - x')(yᵢ - y')) / √(∑(xᵢ - x')² ∑(yᵢ - y')²)

where (xᵢ, yᵢ) are the data points, x' is the mean of the x-values, ȳ is the mean of the y-values, and ∑ represents the sum.

Without actual data points, we can still deduce the correlation coefficient from the slope "m" of the line. The correlation coefficient for a linear relationship is equal to the square root of the coefficient of determination (R-squared), which is the square of the slope "m" in this case.

So, the correlation coefficient (R) is:

R = √((-5)²) = √25 ≈ 5

Therefore, the approximate value of the correlation coefficient for the given graph is 5.

The correct option is: B. 5

Answer:

3(x -1) / (x + 1)(x + 2).

Step-by-step explanation:

(x-1)/(x^2-2x-3)].[(3x-9)/(x+2)

Factoring the denominator  and 3x - 9:

= (x - 1) / (x + 1)(x - 3)  *  3(x - 3) / (x + 2)

The (x - 3)'s  cancel out, so we have:

(x - 1)/(x + 1) * 3 / (x + 2)

= 3(x -1) / (x + 1)(x + 2).

Step-by-step explanation:

a bag of sugar costs $2.12

145 tablespoons of sugar

145:2.12 is the ratio

1:x where x represents per tablespoon cost

2.12 / 145 = 0.01462069 which rounds up to 0.02

Check if it correct:

145 x 0.01462069 = 2.12

Using proportions, it is found that Bob will be 90 feet from the surface of the water after 2 minutes.

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

In this problem, every half-minute, he ascends 15 feet. Hence in 2 minutes = 4 half-minutes, he will have ascended 15 x 4 = 60 feet.

He is 150 feet below the surface of the water, hence after 2 minutes he will be 150 - 60 = 90 feet from the surface of the water.

Explanation:

If the sample is biased, then it does not represent the population. A biased sample favors one or more groups over others.

For example, if the sample consisted of only men, then the sample is biased toward men and leaves out women from the group. Hence, this sample does not represent everyone.
