The isosceles triangle has a base that measures 14 units. A triangle has a base length of 14. The other 2 sides have a length of y.

The value of y, the length of each leg, must be

equal to 7.
between 7 and 14.
greater than 7.
between 14 and 28.

What is the missing reason in the proof? segment addition congruent segments theorem transitive property of equality subtraction property of equality?

Benefit(s) from large economies of scale, in which the costs of goods decrease as output increases. natural monopolles perfect competition

A. find the power of the test, when the null hypothesis assumes a population mean of mu = 450, with a population standard deviation of 156, the sample size is 5 and the true mean is 638.47 with confidence intervals of 95 b. find the power of the test, when the null hypothesis assumes a population mean of mu = 644, with a population standard deviation of 174, the sample size is 3 and the true mean is 744.04 with confidence intervals of 95% c. find the power of the test, when the null hypothesis assumes a population mean of mu = 510, with a population standard deviation of 126, the sample size is 10 and the true mean is 529.44 with confidence intervals of 95
