Answer:
y = -0.85 + 0.09x; $49.82
Step-by-step explanation:
1. Calculate Σx, Σy, Σxy, and Σx²
The calculation is tedious but not difficult.
2. Calculate the coefficients in the regression equation
To two decimal places, the regression equation is
y = -0.85 + 0.09x
3. Prediction
If x = 563,
y = -0.85 + 0.09x = -0.85 + 0.09 × 563 = -0.85 + 50.67 = $49.82
(If we don't round the regression equation to two decimal places, the predicted value is $50.56.)

Answer:
<h3> A. Dilation and reflection</h3>
Step-by-step explanation:
There are the same angles in similar triangles but sides not necessarily.
In congruent triangles there are the same angles and the same sides.
Reflection, rotation or translation changes only position of triangle or mirrors it. Doesn't change the size, so the created triangle is congruent.
Pythagorean Theorem is for triangles not circles.
The equation of a circle is (x - h)² + (y - k)² = radius² where (h, k) is the center.
Plug in your given information and simplify.
(x - (- 1))² + (y - 2)² = (3)²
(x + 1)² + (y - 2)² = 9 is your equation.
<span>0.150 x $152 = $22.80.
</span>
$152 - $22.80 = $129.20
The cost of the coat would be $129.20
