Answer:
C. becomes narrower
Step-by-step explanation:
If the confidence level is reduced from 95% to 90%, then, the confidence interval for u becomes narrower, i.e., we are less sure that the true value of u is contained inside the new interval. With a 95% confidence interval there is a probability of 0.95 that the parameter u is inside the interval and with a 90% confidence interval there is a probability of 0.90 that the parameter u is inside the interval.
So it would be one half of the base times the hight
Answer:Y=6
Step-by-step explanation:
Y=-x+7
For -x put 1 for the -x
So y=-1+7
Y=6
If a triangle is inscribed in a circle, and its hypotenuse is the diameter, it is automatically a right triangle.
Using the Pythagorean theorem, (diameter AB)^2 = (AC)^2 + (BC)^2
AB^2 = 144 + 25 = 169
AB = 13
Therefore the radius is 13/2 = 6.5 units.
