Triangle ABC ~ Triangle QPR
by AA
Step-by-step explanation:
Remember, the angles in a triangle <em><u>always</u></em> add up to 180°. So if there are 2 given angles in a triangle, you can subtract them from 180° to give you your third angle. Using this, you were able to find that angle A = 73° and angle P = 65°, making the 2 triangles congruent by AA.
Answer:
There is a significant decrease in the average price homes.
Step-by-step explanation:
Let X represent the prices of homes sold in the U.S. in the past year
given that
Create hypotheses as
(Left tailed test at 5% significance)
Mean difference = -10000
Std error of mean =
Since population std deviation is known, we can do z test
Z = mean diff/std error = -2.50
p value = 0.00621
Since p <0.05 we reject null hypothesis.
There is a significant decrease in the average price homes.
