Answer:
1. H0: u = 500
2. H1: u <500
3. One sample t test
Step-by-step explanation:
1. The null hypothesis in this question would be
H0: u = 500
2. The alternative hypothesis would be
H1: u < 500
3. The test that we are going to be using is the one sample t test. This test is used to test hypothesis. It would make a comparison of h0 to the mean of the sample. Now we are using this here because the sample standard deviation was given

PLEASE HELP WILL GIVE BRAINLEIST!!! What type of angles are ∠4 and ∠8?
Answer:
Corresponding Angles
Step-by-step explanation:
They are both in the same positions but just on different lines meaning they are corresponding :)
The angle 4 and angle 8 are corresponding angles because line b and line c are parallel to each other and intersected by a line a option (D) is correct.
What is an angle?When two lines or rays converge at the same point, the measurement between them is called a "Angle."
As we can see in the figure, the line b and line c are parallel to each other and intersected by a line a.
The angles 1, 2, 3, 4, 5, 6, 7, and 8 formed.
The angles 1 and 4, angle 2 and 3 are vertically opposite angles.
Similarly, 5&8 and 6&7 are vertically opposite angles.
The angle 4 and angle 8 are corresponding angles.
Thus, the angle 4 and angle 8 are corresponding angles because line b and line c are parallel to each other and intersected by a line a option (D) is correct.

major arc BRA is 3/2 the length of minor arc BSA. the length of major arc BRA is 6pi centimeters. what is the radius of the circle?
9514 1404 393
Answer:
5 cm
Step-by-step explanation:
The given arcs have the ratio ...
BRA : BSA = (3/2) : 1 = 3 : 2
Then BRA is 3/(3+2) = 0.6 of the total circumference of the circle.
0.6(2πr) = 6π . . . . . BRA is 6π long
r = 6π/(1.2π) . . . . . . divide by the coefficient of r
r = 5 . . . . centimeters

Find the volume of the given solid. Bounded by the cylinder y2 + z2 = 16 and the planes x = 2y, x = 0, z = 0 in the first octant
Answer:
[tex]\mathbf{ \dfrac{128}{3}}[/tex]
Step-by-step explanation:
Given that:
[tex]y^2 + z^2 = 16; \\ \\ where; \ x = 2y , x =0, z= 0[/tex]
[tex]Replace \ z = 0 \ \text{in the given equation ;} y^2+z^2=16[/tex]
[tex]Then;[/tex]
[tex]y^2 = 16 \\ \\ y = \sqrt{16} \\ \\ y = \pm 4[/tex]
[tex]\text{So; in 1st octant \ limits of y }= 0 \to 4 \ \text{and for x }= 0 \to 2y[/tex]
∴
[tex]\text{Volume of solid: (V) = }\int ^{4}_{y=0} \int ^{2y}_{x=0} \sqrt{16-y^2} \ dxdy \\ \\ = \int^4_{y=0} \sqrt{16 -y^2} \ (x)^{2y} _o \ dy \\ \\ = \int^4_{y=0}\sqrt{16 -y^2} (2y -0) \ dy \\ \\ V = \int^{4}_{y=0} \ 2y \sqrt{16 - y^2} \ dy[/tex]
[tex]Now, let:\\\\ 16 - y^2 = u \\ \\ -2ydy = du \\ \\ 2ydy = -du \\ \\ Hence, when \ y = 0; u = 16 \\ \\ and \\ \\ when \ y = 4 \ then \ u = 0[/tex]
∴
[tex]V = \int ^4 _{y=0} \ 2y \sqrt{16 -y^2 } \ dy \\ \\ = \int ^0_{16} - \sqrt{u}\ du \\ \\ = - \int^0_{16} \ u^{^{\dfrac{1}{2}}} \ du \\ \\ = \Bigg [\dfrac{u^{^{\dfrac{1}{2}+1}}}{\dfrac{1}{2}+1 } \Bigg]^0_{16} \\ \\ =\Bigg[ -\dfrac{u^{\dfrac{3}{2}}}{\dfrac{3}{2}}^0_{16} \Bigg] \\ \\[/tex]
[tex]= - \dfrac{2}{3}\Big( u^{\dfrac{3}{2}}\Big)^0_{16} \\ \\ = - \dfrac{2}{3} \Big(0^{^\dfrac{3}{2}}}- 16^{^{\dfrac{3}{2}}}\Big ) \\ \\ = - \dfrac{2}{3} \Big(0 - (4^2)^{^{\dfrac{3}{2}}}\Big ) \\ \\ = - \dfrac{2}{3} \Big(-(4)^{3}}\Big )[/tex]
[tex]= - \dfrac{2}{3} \Big(64\Big )[/tex]
∴
[tex]\mathbf{V = \dfrac{128}{3}}[/tex]

Answer:
61
Step-by-step explanation:
Arc AC = 180
Arc DC = 58
Arc AC = Arc AD + Arc DC
180 = Arc AD + 58
122 = Arc DC
Tangent Chord Angle = 1/2Intercepted Arc
Angle DBA = 1/2 Arc DC
Angle DBA = 1/2 (122)
Angle DBA = 61
