Answer:
Step-by-step explanation:
Because of the Isosceles Triangle Theorem, the angles across from the congruent sides will be congruent. That means that the angle x also measures 42 degrees.
Answer:
A-B = 6x^2-7x-6
Step-by-step explanation:
A = 5x^2-4x-11
B = x^2+3x-5
A-B = (5x^2-4x-11) - (-x^2+3x-5) = 5x^2-4x-11+x^2-3x+5 = 6x^2-7x-6
Based on the regression line, and the data points, the sum of squared residuals is 22.
<h3>What is the sum of squared residuals?</h3>
The squared residual can be found as:
= (y - 3 + 2x)²
For point (4 , 8)
= (8 - 3 - 2(4))²
= 9
For point (2 , 5)
= (5 - 3 - 2(2))²
= 4
For point (1, 2)
= (2 - 3 - 2(1))²
= 9
The sum of squared residuals is:
= 9 + 4 + 9
= 22
Full question is:
The regression line = 3 + 2x has been fitted to the data points (4,8), (2,5), and (1,2). The residual sum of squares will be:

Answer: 16 square feet
Step-by-step explanation: In order to calculate how much total screen she needs you need to calculate each section.
The small ends are 2 ft x 1 ft, so you need 2 feet for each end, or 4 feet total.
The long sides are 3 ft x 2 ft, so you need 6 feet for each end, or 12 feet total.
The total screen needed for the sides is 4 + 12 = 16 square feet.
