Answer:
800
Step-by-step explanation:
Answer:
decreases.
Step-by-step explanation:
Type II error is one in which we fail to reject the null hypothesis that is actually false. Null hypothesis is a statement that is to be tested against the alternative hypothesis and then decision is taken whether to accept or reject the null hypothesis. The power of Type II error is 1 -
. As the power increases the probability of Type II error decreases.
Answer:
![3,726\ m^{2}](https://tex.z-dn.net/?f=3%2C726%5C%20m%5E%7B2%7D)
Step-by-step explanation:
step 1
Find the scale factor
we know that
If two figures are similar, then the ratio of its corresponding sides is equal to the scale factor
Let
z----> the scale factor
x----> corresponding side of the larger trapezoid
y----> corresponding side of the smaller trapezoid
![z=\frac{x}{y}](https://tex.z-dn.net/?f=z%3D%5Cfrac%7Bx%7D%7By%7D)
we have
![x=64\ m](https://tex.z-dn.net/?f=x%3D64%5C%20m)
![y=12\ m](https://tex.z-dn.net/?f=y%3D12%5C%20m)
substitute
![z=\frac{64}{12}](https://tex.z-dn.net/?f=z%3D%5Cfrac%7B64%7D%7B12%7D)
step 2
Find the area of the larger trapezoid
we know that
If two figures are similar, then the ratio of its areas is equal to the scale factor squared
Let
z----> the scale factor
x----> area of the larger trapezoid
y----> area of the smaller trapezoid
![z^{2}=\frac{x}{y}](https://tex.z-dn.net/?f=z%5E%7B2%7D%3D%5Cfrac%7Bx%7D%7By%7D)
we have
![z=\frac{64}{12}](https://tex.z-dn.net/?f=z%3D%5Cfrac%7B64%7D%7B12%7D)
![y=131\ m^{2}](https://tex.z-dn.net/?f=y%3D131%5C%20m%5E%7B2%7D)
substitute
![(\frac{64}{12})^{2}=\frac{x}{131}](https://tex.z-dn.net/?f=%28%5Cfrac%7B64%7D%7B12%7D%29%5E%7B2%7D%3D%5Cfrac%7Bx%7D%7B131%7D)
![x=(\frac{4,096}{144})(131)](https://tex.z-dn.net/?f=x%3D%28%5Cfrac%7B4%2C096%7D%7B144%7D%29%28131%29)
![x=3,726\ m^{2}](https://tex.z-dn.net/?f=x%3D3%2C726%5C%20m%5E%7B2%7D)
Answer:
a = 6, b = -2, c = 3
Step-by-step explanation:
6x² - 2x + 3 = 0
a = 6, b = -2, c = 3
