A small dealership leased 21 Suburu Outbacks on 2-year leases. When the cars were returned at the end of the lease, the mileage

was recorded (see below). 40,060 24,960 14,310 17,370 44,740 44,550 20,250 33,380 24,270 41,740 58,630 35,830 25,750 28,910 25,090 43,380 23,940 43,510 53,680 31,810 36,780 picture Click here for the Excel Data File (a) Is the dealer's mean significantly greater than the national average for 2-year leases, which is 30,000 miles? Using the 10 percent level of significance, choose the appropriate hypothesis. H0: μ ≤ 30,000, reject H0 if tcalc > 1.325 H1: μ ≤ 30,000, reject H0 if tcalc > 1.325 H0: μ > 30,000, reject H1 if tcalc > 1.325 H1: μ > 30,000, reject H1 if tcalc > 1.325 a b c d (b-1) Calculate the test statistic. (Round your answer to 2 decimal places.) Test statistic (c) The dealer's cars show a significantly greater mean number of miles than the national average at the 10 percent level.

Two quadrilaterals are congruent. One has vertices P, N, O, and M, and the other has vertices S, T, V, and U. These correspondin
Bogdan [553]

Answer: NPOM \cong VUTS and OPNM \cong TVUS will be correct.

Explanation:

Given: two quadrilaterals having verticals P, N, O,M and S,T,V,U are congruent,  where, OM is congruent or equal to TS and \angle P\cong \angle U.

in quadrilaterals NPOM and  VUTS-

since, the condition \angle P = \angle U

and, side UV=side  OM   follow for the above quadrilateral. (According to the figure)

then we can say according to the property of quadrilateral, their corresponding sides must be congruent. so they are congruent.

similarly, these two conditions also follow in the case of OPNM \cong TVUS

we can understand it by making the figures.
