<h3>
Answer:</h3>
A) Quadrilateral
<h3>
Explanation:</h3>
Here the figure is not a rectangle and parallelogram as it does not have two parallel sides. The figure cannot be considered as a trapezoid as the shape does not have either one parallel side. All the sides are in its unique form. Though it has four sides so it can be considered as a Quadrilateral.
The Answer is : C.) h(x) = -4(x − 2)(x + 2)
1. Check the picture attached.
2. m(AOB)=2x as it is a central angle, intercepting the same arc (AB) as ACB.
3. AO=OB=1, as they are radii of the unit circle.
4. From the cosine theorem:
![AB^{2} =AC^{2} + BC^{2} -2*AC*BC*cos C](https://tex.z-dn.net/?f=%20AB%5E%7B2%7D%20%3DAC%5E%7B2%7D%20%2B%20BC%5E%7B2%7D%20-2%2AAC%2ABC%2Acos%20C)
substituting the known values:
![AB^{2} =1^{2} + 1^{2} -2*1*1*cos x](https://tex.z-dn.net/?f=AB%5E%7B2%7D%20%3D1%5E%7B2%7D%20%2B%201%5E%7B2%7D%20-2%2A1%2A1%2Acos%20x)
![AB^{2} =2 -2*cos x=2(1-cosx)](https://tex.z-dn.net/?f=AB%5E%7B2%7D%20%3D2%20-2%2Acos%20x%3D2%281-cosx%29)
Answer:
A.) No
B.) test statistic = - 3.108
Check explanation
Step-by-step explanation:
H0: m = 105 versus H1: m ≠ 105
Sample size, n = 35, since we have a large sample size, greater than 30.
B.)
xbar = 101.9 ; s = 5.9
Test statistic :
T = (xbar - μ) ÷ (s/√n)
T = (101.9 - 105) / (5.9/√35)
T = - 3.1 / 0.9972820
Test statistic = - 3.11
Pvalue from Tstatistic, df = 34
Pvalue = 0.003772( Pvalue calculator)
Pvalue is the probability of obtaining a value more extreme or exactly that of the test statistic.
At α = 0.01
Pvalue < α ; We fail to reject the Null
