In a test of a particular weight loss program, weights of 40 subjects are recorded before and after the program. The before-and-

after weights result in a correlation coefficient of 0.876. Assuming a 0.05 significance level, find the critical values. Is there sufficient evidence to support the claim of a linear correlation between before-and-after weights?

13. Find the surface area of each figure to the nearest tenth. Show your work.
stiv31 [10]
A. The figure is a triangular pyramid. You can findits surface area by adding up the area of the three faces of the triangle and the area of the base. A derived formula also is used where the SA is equal to 12 times the perimeter of base times the slant height, added to that is the area of the base. The area of the square base is s^2. Its perimeter is 4s.

SA of Pyramid = 12*P*l + s^2
SA of Pyramid = 12*4s*l + 16^2
SA of Pyramid = 12*4(16)*(17) + (16)^2
SA of Pyramid = 11,008 square inches

b.) The formula for the SA of a cone is: 

SA of cone = πr[r+√(h^2+r^2)]
SA of cone = π(3)[(3+√(8^2+3^2)]
SA of cone = 108.8 square inches

Write 17,390,000 in expanded form
scoray [572]

Answer:

The expanded form is:

17,390,000 = 10,000,000 + 7,000,000 + 300,000 + 90,000

Step-by-step explanation:

<em>Expanded form is a way of writing numbers with the mathematics value of digits.</em>

Ex: 7,327 in expanded form is 7,000 + 300 + 20 + 7 = 7,327

<em>So you can write any number in expanded form by adding the values of its digits places</em>

<em>Let us solve the question</em>

The number is 17,390,000

∵ The first digit 1 is in ten-millions place

∴ Its value = 10,000,000

∵ The second digit 7 is in the millions place

∴ Its value = 7,000,000

∵ The third digit 3 is in the hundred-thousands place

∴ Its value = 300,000

∵ The fourth digit 9 is in the ten-thousands

∴ Its value = 90,000

Add all of them

∴ 17,390,000 = 10,000,000 + 7,000,000 + 300,000 + 90,000

The expanded form is

17,390,000 = 10,000,000 + 7,000,000 + 300,000 + 90,000

What is the vertex of y=x² – 8x + 14​
ozzi

Answer:

-2

Step-by-step explanation:

  1. Get the equation in the form y = ax2 + bx + c.
  2. Calculate -b / 2a. This is the x-coordinate of the vertex.
  3. To find the y-coordinate of the vertex, simply plug the value of -b / 2a into the equation for x and solve for y.
