Answer:
<u>The triangular prism shown has 2 triangular faces and 3 lateral faces.</u>
- The triangles are on the ends, and there are three rectangular faces, which are the "lateral" faces because they're not bases.
<u>The area of one triangular face is 7.5 square millimeters.</u>
- Area of triangle = 1/2 b*h = 1/2* 6*2.5 = 1/2*15 = <u>7.5 square millimeters</u>
<u>The surface area of the triangular prism is 135 square millimeters.</u>
- Lateral face area = the sum of the three lateral faces. = 8*6.5 + 8*2.5 + 6*8 = 120 square millimeters
- Surface area = 2(triangle area) + sum of lateral faces = 2(7.5) + 120 = <u>135 square millimeters</u>
Answer:
non linear
Step-by-step explanation:
the graph is showing more of a parabola than a linear line
Answer:
The equation of the least-squares regression line for predicting height from knee height is .
Step-by-step explanation:
Given any collection of pairs of numbers, there always exists exactly one straight line that fits the data better than any other, in the sense of minimizing the sum of the squared errors. It is called the least squares regression line.
The slope-intercept form of a line is
where b is the slope of the line and a is the y-intercept.
We have the following data
To find the equation of the regression line you must:
Step 1: Find and as it was done in the table below.
Step 2: Find the sum of every column.
Step 3: Use the following equations to find a and b
Step 4: Substitute a and b in the regression equation formula
Answer:
supposed to make the subject y then slope is -2
