Yes, every right triangle has two complementary angles.
This is because you know that the interior angles of a triangle have to add up to 180 degrees.
A right angle is 90 degrees, so the remaining two angles have to add up to (180-90) degrees, or 90 degrees.
Two angles whose sum is 90 degrees are complementary.
For a data point measured as y = 3.5 for an x value of x = 1.2, the residual would be 0.1
For given question,
we have been given an equation 2x + 1 that represents an equation for a trendline to the data.
General formula with residual is y = 2x + 1 + r, where r is a residual.
We need to find the residual for a data point measured as y = 3.5 for an x value of x = 1.2
We substitute given values of x and y in the residual equation
y = 2x + 1 + r
For y = 3.5 and x = 1.2,
⇒ 3.5 = 2(1.2) + 1 + r
⇒ 3.5 = 2.4 + 1 + r
⇒ r = 3.5 - 3.4
⇒ r = 0.1
Therefore, for a data point measured as y = 3.5 for an x value of x = 1.2, the residual would be 0.1

Answer:
12
Step-by-step explanation:
1/5 of 30 is 6
there are 24 cupcakes left
half of 24 is 12
12 are left over. These will get vanilla frosting.
