Step-by-step explanation:

Use substitution.

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.

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:

120 cubes

Step-by-step explanation:

We can find the number of smaller cubes that will fit into larger rectangular prism by dividing the volume of prism by the volume of cube.

  Rectangular prism:

       [tex]\sf l = 2\dfrac{1}{2} =\dfrac{5}{2} \ inches\\\\w = 4 \ inches\\\\h =1\dfrac{1}{2}=\dfrac{3}{2} \ inches\\[/tex]

            [tex]\sf \boxed{\text{\bf Volume of rectangular prism= l * w * h}}[/tex]

                                                                 [tex]\sf =\dfrac{5}{2}*4*\dfrac{3}{2}\\\\= 5*1*3\\\\= 15 \ in^3[/tex]

To find the surface area, find the area of the square base and add it to the area of each triangle face. Find the area of the base by multiplying base length by base length. Find the area of each triangle face by multiplying 1/2 * b*h.

Example:

For a base which is 12 by 12. The area is 12 x 12 = 144.

For the triangle face, the area is 1/2 * 12 * 15 = 90. Since there are 4 faces, the total area is 4 * 90 = 360.

Together the surface area is 360 + 144 = 504.
