Answer:
Based on the data, if we find moderate/strong evidence against the null hypothesis and conclude the mean arsenic level of the water is greater than 8.0 ppb, we have made ____________.
a correct decision.
Step-by-step explanation:
Since there is enough evidence to conclude that the mean level of arsenic is greater than 8.0 ppb, the correct decision has been made. There is no type I or type II error. The type I error (called a false positive) occurs if we reject the null hypothesis when it is true. Since we have simply rejected the null hypothesis when the alternate hypothesis is true, and the null hypothesis should be rejected, a correct decision has been made.
Corresponding parts of similar triangles are proportional (CPSTP) is the property used here. Since the triangles are isosceles, then each non-base side is the same. The larger/left triangle has both sides of 215 meters and the smaller/right triangle has both sides of 43.
Let's make a proportion. On the tops are the sides, on the bottoms are the bases. On the left is the larger triangle, on the right is the smaller triangle. Keeping the pieces straight is what makes the proportion work.
To solve for x we can cross multiply.
215(x) = (230)(43)
215x = 9890
x = 46 after dividing both sides by 215
Thus the proportion is and the base is 46 meters.
Answer:

Step-by-step explanation:
statement reason
1.in triangle ADB and ADC
a. AB=AC a.given
b.BD=CD b. radii of same circle
c. AD=AD c. common side
2. ∵triangle ADB is congurent to 2. by S.S.S axiom
ADC
B is the correct statement to start with. It will eliminates y.
