The equation yˆ=0.8579x+73.4728 models the mass of a mammal’s brain, in grams, where x is the mass of the mammal, in kilograms. according to the regression equation, what is the approximate mass of a mammal's brain with a body that has a mass of 60 kg?

125 grams.

Step-by-step explanation:

We have been given an equation , which models the mass of a mammal’s brain, in grams, where x is the mass of the mammal, in kilograms.

To find the approximate mass of a mammal's brain with a body that has a mass of 60 kg, we will substitute in our given equation.

Therefore, the mass of the mammal's brain is approximately 125 grams.

10000

step-by-step explanation: divide by 2,

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.
