In order to estimate the mean 30-year fixed mortgage rate for a home loan in the United States, a random sample of 10 recent loans is taken. The average calculated from this sample is 6.40%. It can be assumed that 30-year fixed mortgage rates are normally distributed with a population standard deviation of 0.5%. Compute 95% and 99% confidence intervals for the population mean 30-year fixed mortgage rate.

it will be a cylinder. with a diameter of 8 and 4 single pieces high

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.

the answer to question 1 is -8, 28.
