Answer:
The null hypothesis is [tex]H_0: \mu = 13[/tex]
Step-by-step explanation:
Before a high-school football game the footballs were inflated to p = 13 psi (pounds per square inch).
This means that, as we are going to test the inflation levels before and after the game, we test at the null hypothesis that it is of 13 psi, that is:

Are the polynomial functions even or odd ?
If you mirror the graph along the x axis and it lies on itself ( mirror image) it is even, if not it is odd.
If you mirror the top graph the high/ low points would be opposite so the top graph is odd
The bottoms graph can be mirrored so the bottom graph is even.
Write a paragraph (4-5 sentences) explaining how we can help or change racism to black people
No copying from internet please
Answer
A few ways we could stop racism against black people in this country is to stop the perpepuation of black stereotypes in media. Such as the loud, aggressive black man, or the rude, catty black woman. It causes a harmful view on black people and can result in racial profiling. Another way to combat this racism is to fight off systemic racism. Black people who have unique names, usually African names, are more likely to get turned down for a job when they turn in their resume to an establishment. This is because they automatically assume that they'll be trouble, and won't be a good worker.
Find the circumference of a circle whose radius is 4 feet. Use 3.14 for Pi.
Answer:
25.12
Step-by-step explanation:
The formula of the circumference of a circle is: C = 2(pi)(r)
Plug in 3.14 for pi and 4 for the radius.
C = 2(3.14)(4)
Multiply.
C = 25.12
The equation of a circle is (x-1)^2 +(y-2)^2=4. What is the center of the circle and what is the radius of the circle?
Answer:
Step-by-step explanation:
(x-1)²+(y-2)² =4 compare the given equation with the general one
(x-h)² +(y-k)² =r², where (h, k) are coordinates of the center and r is radius
so center is at ( 1, 2) and radius is 2

Find the measure of the arc or angle indicated. NO LINKS.
9514 1404 393
Answer:
10. A) 120°
11. D) 40°
12. D) 54°
13. A) 101°
Step-by-step explanation:
The applicable rules of angles and arcs are ...
the whole is the sum of the partsarcs of a circle total 360°an inscribed angle intercepts an arc of twice its measure__
10) Angles C and L intercept the same arc (DE) so will have the same measure.
15x = 16x -4
4 = x . . . . . . . . add 4-15x
arc DE = 2(15x) = 30(4) = 120 . . . degrees
__
11) Arc VW is twice the measure of angle X, so ...
9x +8 = 2(5x)
8 = x . . . . . . . . . subtract 9x
∠VXW = 5x = 5(8) = 40 . . . degrees
__
12) Arc EFG is twice the measure of angle W, so ...
70° +FG = 2(88°)
FG = 106° . . . . . . . . . subtract 70°
Arc FGW is twice the measure of angle E, so ...
106° +GW = 2(80°)
GW = 54° . . . . . . . . . . subtract 106°
__
13) Arc ST is twice the measure of angle R. The sum of arcs is 360°.
RS +ST +TR = 360°
119° +2(70°) +TR = 360°
TR = 101° . . . . . . . . subtract 259°

13. What is the pressure on the bottom of a water tank filled to a depth of 4 feet? O A. 1.73 psi OB. 62.4 psi C. 249.6 psi D. 184.2 psi
Pressure is defined as the force applied perpendicular to an object's surface per unit area across which that force is dispersed. The correct option is A.
What is pressure?Pressure is defined as the force applied perpendicular to an object's surface per unit area across which that force is dispersed.
The density of water is equal to 997 kg/m³, while the acceleration due to gravity is 9.81 m/s², also, given the depth of the water is 4 feet(1.2192 meters). Therefore, the pressure on the bottom of a water tank filled to a depth of 4 feet is,
Pressure = ρ × g × H = 997 × 9.81 × 1.2192 = 11924.47 N/m²
Now, If we convert the pressure from N/m² to psi, then we have to divide 11924.47 N/m² by 6895, therefore, the pressure will be,
Pressure = 11924.47 N/m² / 6895 = 1.729 psi ≈ 1.73 psi
Hence, the correct option is A.

What is the length of X?
Answer:
x = 85
Step-by-step explanation:
Its a Pythagorean theorem question, being a^2 + b^2 = c^2.
and knowing that 168 is the entire base we would divide by 2 to get 84 as b.
The new equation would be 13^2 + 84^2 = c^2
Then squaring them to get 169 + 7056 = c^2
Then add them together and square root them [tex]\sqrt{x}[/tex] 7225 = c
The square root is 85 making it equal x.

Answer:
[tex]a + b + c = \pi \\ = > c= \pi - a - b \\ < = > \tan(c) = \tan(\pi - a - b) = -\tan(a + b) [/tex]
Step-by-step explanation:
we have:
[tex] \tan(a) + \tan(b) + \tan(c) \\ = \tan(a) + \tan(b) - \tan(a + b) \\ = \tan( a) + \tan(b) - \frac{ \tan(a) + \tan(b) }{1 - \tan(a) \tan(b) } \\ = \frac{ ( \tan(a) + \tan(b) ) \tan(a) \tan(b) }{ \tan(a) \tan(b) - 1 } (1)[/tex]
we also have:
[tex] \tan(a) \tan(b) \tan(c) \\ = - \tan(a) \tan(b) \tan(a + b) \\ = \frac{ -(\tan( a ) + \tan(b) ) \tan(a) \tan(b) }{1 - \tan(a) \tan(b) } \\ = \frac{( \tan(a) + \tan(b)) \tan(a) \tan(b) }{ \tan(a) \tan(b) - 1 } (2)[/tex]
