By observing a set of data values, Tina used a calculator for the engine speed and predicted horsepower to get an equation for the least-squares line: y = 10 + 30x Based on the data that Tina collected, select the statement that is TRUE.
a.) The horsepower associated with an engine speed of 0.5 rpm would be 40 hp
b.) The horsepower associated with an engine speed of 3.5 rpm would be 110 hp.
c.) The horsepower associated with an engine speed of 1.5 rpm would be 70 hp.
d.) The horsepower associated with an engine speed of 2.5 rpm would be 85 hp

d) 48

step-by-step explanation:

solution:

we have to construct

∠m nt ≅ ∠p qr

the steps to draw this construction are

step 1: use a compass to draw an arc from point q which intersects the side pq at point a and the side qr at point b.

step 2: draw a segment nt and use the same width of the compass to draw an arc from point n which intersects the segment nt at a point x.

step 3:

step 4: join points n and y using a straightedge.

step 3:

option (d).maintaining the same width of the compass as ab, draw an arc from point x such that it intersects the arc drawn from n in a point y.

to draw   congruent angles , 1. width of compasses while drawing two angles should be same i.e from point at which angle has to be drawn, 2.the distance between the two points where the compass intersects the two sides should be same while drawing any two congruent angles.
