Consumer Reports is conducting tests to determine the distance a certain car model will travel on one gallon of gas. In a sample of 9 cars, the average is found to be 28.2 miles. If the standard deviation for the model is 2.7 miles, find a 99% confidence interval for the mean distance of these cars using one gallon of gas. Estimate your answers according to the values in the problem miles to miles

tyty jry j y yj yttj yhgtyj y ghyj ytthj

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.
