Compare the given dimensions of four triangles. Which triangle is possible to construct?

2 answers:

7 0

When 3 Triangle sides are known:
The longest side must be less than the sum of the other 2 sides.
5, 12 and 13 - can be constructed
2, 11 and 15 - can be constructed
3, 7 and 11 - CAN'T be constructed - the longest side is greater than the sum of the other two.
4, 8 and 15 - CAN'T be constructed - the longest side is greater than the sum of the other two

A manufacturer of piston rings for automobile engines frequently tests the width of the rings for quality control. Last week, a

kozerog [31]

Answer:

a) 74.0353 < u < 74.0367

b) 74.036 < u

Step-by-step explanation:

Given:

- Sample size n = 15

- Standard deviation s.d = 0.0001 in

- Sample mean x_bar = 74.036

Find:

A) Calculate the 99% two-sided confidence interval on the true mean piston diameter.

Solution:

- For 99% CI, We have a = 0.01 , and Z_a/2 = 2.58

------> (x_bar - Z_a/2*s.d / sqrt(n)) < u < (x_bar + Z_a/2*s.d / sqrt(n))

------> (74.036 - 2.58*0.0001 / sqrt(15)) < u < (74.036 + 2.58*0.0001 / sqrt(15))

------> 74.0353 < u < 74.0367

Find:

B) Calculate the 95% one-sided lower confidence interval on the true mean piston diameter.

Solution:

- For 95% lower CI, We have a = 0.05 , and Z_a = 1.645

------> (x_bar - Z_a/2*s.d / sqrt(n)) < u

------> (74.036 - 1.645*0.0001 / sqrt(15)) < u

------> 74.036 < u
