What’s the volume and surface area
Surface area and volume are calculated for any three-dimensional geometrical shape. The surface area of any given object is the area or region occupied by the surface of the object. Whereas volume is the amount of space available in an object.

Answer:
[tex]170[/tex]
Step-by-step explanation:
The angle 42x+1 is the inscribed angle of Arc WX. This means Arc WX is twice of 42x+1.
[tex]wx = 2(42x + 1)[/tex]
We can add up that and the other arcs to 360.
[tex]2(42x + 1) + 29x - 1 + 65x + 3[/tex]
[tex]84x + 2 + 29x - 1 + 65x + 3 = 360[/tex]
[tex]178x + 4 = 360[/tex]
[tex]178x = 356[/tex]
[tex]x = 2[/tex]
Plug in 2 for WX.
[tex]84(2) + 2 = 170[/tex]

What is the mean of the data set?
{20, 1, 14, 14, 9,8}
Answer and Step-by-step explanation:
To find the mean, you have to add all of the data together, then divide by the amount that there is.
So, when adding together the data, we get 66. We have 6 values, so we will divide 66 by 6.
66 divided by 6 is 11.
The mean of the data set is 11.

Step-by-step explanation:
Labor economists have extensively researched the determinants of earnings. Invest-ment in human capital, measured in years of education, and on the job training aresome of the most important explanatory variables in this research. You decide toapply earnings functions to the field of sports economics by finding the determinantsfor baseball pitcher salaries. You collect data on 455 pitchers for the 1998 baseballseason and estimate the following equation using OLS and heteroskedasticitv-robust standard errors:
Ln (Eami) = 12.45 + 0.052 x Years + 0.00089 x Innings + 0.0032 x Saves
(0.08) (0.026) (0.00020) (0.0018)
- 0.0085 x ERA, R^2 = 0.45, SER = 0.874
(0.0168)
where Earn is annual salary in dollars, Years is number of years in the major leagues, Innings is number of innings pitched during the career before the 1998 season, Saves is number of saves during the career before the 1998 season, and ERA is the earned run average before the 1998 season.
A) What happens to earnings when the pitcher stays in the league for one additional year? Compare the salaries of two relievers, one with 10 more saves than the other. What effect does pitching 100 more innings have on the salary' of the pitcher? What effect does reducing his ERA by 1.5? Do the signs correspond to your expectations? Explain.
B) Are the individual coefficients statistically significant? Indicate the level of significance you used and the type of alternative hypothesis you considered.
C) Although you are quite impressed with the fit of the regression, someone suggests that you should include the square of years and innings as additional explanatory variables. Your results change as follows:
Ln (Eami) = 12.15 + 0.160 x Years + 0.000268 x Innings + 0.0063 x Saves
(0.05) (0.039) (0.00030) (0.0010)
-0.0584 x ERA - 0.0165 x Years - 0.00000045 x Innings
(0.0165) (0.0026) (0.00000012)
R^2 = 0.69, SER = 0.666
What is her reasoning? Are the coefficients of the quadratic terms statistically significant? Are they meaningful?
D) Calculate the effect of moving from two to three years, as opposed to from 12 to 13 years.
E) You also decide to test the specification for stability across leagues (National League and American League) by including a dummy variable for the National League and allowing the intercept and all slopes to differ. The resulting F-statistic for restricting all coefficients that involve the National League dummy variable to zero, is 0.40. Compare this to the relevant critical value from the table and decide whether or not these additional variables should be included.
Answer:
Kindly check explanation for other solutions
Years, Inning and saves are statistically significant ; ERA is not.
Step-by-step explanation:
Earning for staying one additional year :
Multiply slope value of years * 1 = 0.052 * 1 * 100 % = 5.2% (earning increases by 5.2%)
Relives with 10 more saves :
10 * 0.0032 * 100% = 3.2% (earning increases by 3.2%)
Having 100 more innings :
100 * 0.00089 * 100% = 8.9%
If ERA is reduced by 1.5 ; earning will increase by (0.0085*100)% * 1.5 = 1.275%
B.) At 5% level of confidence :
α = 1.64
Years = 0.052/0.026=2
Inning = 0.00089/0.00020 = 4.45
Saves = 0.0032/0.0018 = 1.78
ERA = 0.0085/0.0168 = 0.51
Years, Inning and saves are statistically significant as they are greater than α ; As for ERA, it is not statistically significant (0.51 < 1.64)
Which of the prisms below must have symmetry with respect to a point? (Select all that apply.
(PLEASE HELP ME) NO LINKS OR ABSURD ANSWERS. I WILL REPORT)
I WILL GIVE BRAINLEST FOR THE CORRECT ANSWER>
Answer:
Option III
Step-by-step explanation:
All regular figures have a point at which one can draw a line of symmetry. A figure classifies are regular if all of its sides and angles are congrunet. It is given that figure (III) has a regular base, thus it is most probable that it has symmetry with respect to a point.
Use either the shell method or the disk/washer method to find the volume of the solid (Calculus Help!!!)
Integrating with shells is the easier method.
V = 2π ∫₁³ x (√x + 3x) dx
That is, at various values of x in the interval [1, 3], we take n shells of radius x, height y = √x + 3x, and thickness ∆x so that each shell contributes a volume of 2π x (√x + 3x) ∆x. We then let n → ∞ so that ∆x → dx and sum all of the volumes by integrating.
To compute the integral, just expand the integrand:
V = 2π ∫₁³ (x ³ʹ² + 3x ²) dx
V = 2π (2/5 x ⁵ʹ² + x ³) |₁³
V = 2π ((2/5 × 3⁵ʹ² + 3³) - (2/5 × 1⁵ʹ² + 1³))
V = 4π/5 (9√3 + 64)

Find the area of the shaded region.
Answer:
60.5m^2
Step-by-step explanation:
the area of the square
=11m×11m
=121m^2
the area of triangle
=11m×11m÷2
=121m^2÷2
=60.5m^2
the area of the shaded region
=121m^2-60.5m^2
=60.5m^2

Answer:
7)Bagel costs $3.5 and muffin cost $1.25
8) Ticket is $9 while snacks are $2
9) Correct because left hand side is zero
10) Correct because they both have same slope and same y-intercept
Step-by-step explanation:
7) Let bagel be x and muffin be y.
Thus;
For Aaron;
x + 3y = 7.25 - - - (1)
For bee;
x + 2y = 6 - - - (2)
Subtract eq 2 from eq 1 to get;
y = 1.25
Put 1.25 for y in eq 2;
x + 2(1.25) = 6
x + 2.5 = 6
x = 6 - 2.5
x = 3.5
Bagel costs $3.5 and muffin cost $1.25
8) Let movie ticket be x and snacks be y.
Thus;
2x + 3y = 24 - - - (1)
3x + 4y = 35 - - - (2)
Multiply eq(1) by 3 and eq(2) by 2 to get;
6x + 9y = 72 - - - (3)
6x + 8y = 70 - - - (4)
Subtract eq 4 from eq 3 to get;
y = 2
Put 2 for y in eq 3;
6x + 9(2) = 72
6x + 18 = 72
6x = 72 - 18
6x = 54
x = 54/6
x = 9
Ticket is $9 while snacks are $2
9) using elimination, subtract eq 1 from eq 2, we will see that the entire left hand side is equal to zero.
Thus, no solution exists because we can't isolate the variable to get an answer.
10) The answer is correct because for a system of 2 simultaneous equations to have infinite solutions, they both have to have the same y-intercept and also same slope.
In this case, their y-intercept which is when x is 0 is;
3(0) + y = 9
y = 9
Their slope is also the same equal to 3.

Azim wants to buy a tablet computer that is priced at 180.50. If sales tax rate on the computer is 8%, how many dollars and cents will Azim spend on the sales tax?
Answer:
$14.44
Step-by-step explanation:
I'm pretty sure it's 14.44 because It says only the sales tax not the whole price together so you would take 8% turn it into .08 and multiply 180.50 by .08 and get 14.44 which is the sales tax. And if you were looking for the total it would be 194.94 but that's not what this question is asking(:
