The competitive advantage of small American factories such as Tolerance Contract Manufacturing lies in their ability to produce

Tom [10]

Answer:

Following are the solution to the given question:

Step-by-step explanation:

Please find the complete question in the attached file.

$H_0: \sigma^{2} \leq 0.0008\\\\H_a: \sigma^{2} > 0.0008$

The testing states value is:

$\to x^2=\frac{(n-1)s^2}{\sigma^2}=32.6250$

therefor the $\rho - \ value = 0.2931$

Through out the above equation its values Doesn't rejects the H_0 value, and its sample value doesn't support the claim that although the configuration of its dependent variable has been infringed.

20 points helppppppppppppppppppppppppppppp PLZZ anyone solve this ASAP

Sonja [21]

Answer:

$cos^{-1}(cos\frac{ 7π}{6})=cos^{-1}(cos\frac{7*180}{6})$

$cos^{-1}(cos{210})$

$cos^{-}(cos(180+30))$

[since in third quadrant cos 30=- $\frac{\sqrt{3}}{2}]$

$cos^{-}(- \frac{\sqrt{3}}{2})$

:150°or $\frac{5π}{6}$

150°or  $\frac{5π}{6}$ is a required answer.

If the same BLANK number is multiplied to each side of a true inequality, the inequality sign is reversed to make the resulting

Maurinko [17]

Answer: Negative
If the same negative number is multiplied to each side of a true inequality, then the inequality sign flips to make the new inequality true as well

Example:
Take 1 < 5 and multiply both sides by -2 and we get -2 > -10. The "less than" sign flips to "greater than" since -2 < -10 is false. The value of -10 is further to the left of -2 so -10 is smaller in value. The negative basically takes the complete opposite which is why the flip must happen.

This sign flip rule does not happen if you multiply both sides by a positive number.

Martin and Alexia are rock climbing each person's rate stays the same for the first hour they climb mountain climbers 3 1/3 mete

Minchanka [31]

1. If Martin climbs 3 1/3 meters in the first one 1/6 hour, then he climbs

$3\dfrac{1}{3}\cdot 6=\dfrac{10}{3}\cdot 6=20$ meters per hour. Then, option A is correct and options C and E are false.

2. If Alexia climbs 17 1/2 in the first 5/6 hour, then she climbs

$17\dfrac{1}{2}\cdot \dfrac{6}{5}=\dfrac{35}{2}\cdot \dfrac{6}{5}=21$ meters per hour and it takes Alexia $\dfrac{1}{21}$ of an hour to climb 1 meter. Then options B and D are correct and option F is false.

Answer: correct options are A, B and D.
