You can earn 5 coins The speed limit on Main Street is 20 miles per hour. Which inequality shows the speed, s, that cars should drive on Main Street?
Answer:
s ≤ 20
Step-by-step explanation:
The speed limit refers to the maximum velocity a vehicle is allowed to move. Therefore, for a certain street like the one in the scenario abive, with a speed limit of 20 miles per hour, then, the maximum allowable speed on the highway is 20 miles per hour. Meaning vehicles can move at that speed or below. However, moving above that speed is a violation of the speed limit rule. Hence. The speed limit could be represented by the inequality :
Speed limit is less than or equal to 20 miles per hour
S ≤ 20

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)

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.

63 * 2 = m of arc DF
arc DF = 126
180 - 126 = 54
Arc FE = 54
Answer:
arc FE = 54°
Step-by-step explanation:
Because DE is a diagonal, ∠DFE is 90°.
∠FDE = 180° - 90° - 63° = 27°
arc FE = 2(∠FDE) = 2(27°) = 54°

Answer:
$30 per Ticket
Step-by-step explanation:
There are 3 friends coming along you so that means you have to divide one number by 3. You have a $20 coupon so that meant you had to subtract 20 from 120. 20-120=100.
Now, you have to divide 100 by the 3 friends then add 5 to each number.
3 divided by 100=25+5=30
So, $30 is your answer

What is a rectangle?In two-dimensional planning geometry, it is the region that the rectangle occupies. It is described as a type of two-dimensional geometry where the angle between neighboring sides is 90 degrees. It is a specific kind of quadrilateral.
The following formula can be used to determine a rectangle's area:
Rectangle area = length x width
It given that, the diagonal length of the TV is 76 inches, the width of the TV is 66 inches,
We have to find the length of the television. Apply the Pythagoras theorem,
AC²=AB²+BC²
76²=66²+BC²
BC²=76²-66²
BC²=1420
BC=√1420
BC=37.68
Thus, the obtained length of the television will be 37.68

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(:
Lobe-finned fishes were present in the oceans of the world approximately 400 million years ago. The first tetrapods (vertebrates that had limbs and could move on land) date to about 365 million years ago. One hypothesis states that early tetrapods evolved from lobe-finned fishes. What is the best plan for testing this hypothesis?
Answer:
comparing the arrangements of bones in the fins of lobe-finned fishes and limbs of the earliest tetrapods.
Step-by-step explanation:
Based on the modern method of archeological findings used, it is the view of some scientists that the best plan to test the hypothesis (assumption) that early tetrapods might have evolved from lobe-finned fishes involves comparing the arrangements of bones in the fins of lobe-finned fishes and limbs of the earliest tetrapods.
