The simplest form would be in a fraction 5/3
Answer:
$11,728
Step-by-step explanation:
Twice a year, for 4 years is 8 times
516×8 = 4128
Yearly for 4 years is 4 times
700×4 = 2800
Every month for 4 years is 48 times
100×48 = 4800
Minimum expenditure:
4128 + 2800 + 4800 = $11,728
Answer:
273.38
Step-by-step explanation:
815.70 * 6.2% = 50.57
815.70 * 1.45% = 11.83
815.70 * 19% = 154.95
Add those 3 totals to the additional $56 in federal tax
56+50.57+11.83+154.95 = 273.35
Answer:
Step-by-step explanation:
Hello!
a)
The dependent variable is
Y: length of a dugong
The explanatory variable is
X: age of a dugong
You need to estimate the linear regression of the length of the dugongs as a function of their age.
Using the given data I've estimated the regression using a statistic software:
The regression model is E(Yi)= α + βXi
The estimated model is ^Yi= a + bXi
Where a is the estimate of the intercept and b is the estimate of the slope:
a= 2.02
b= 0.03
And the estimate of the population variance of the error is Se²= 0.03
The estimated regression equation is ^Yi= 2.02 + 0.03Xi
b)
You have to estimate the length of a dugong when its age is 11 years using the model, for this all you have to do is replace X=11 in the regression line and calculate the corresponding ^Y value:
^Yi= 2.02 + 0.03*11= 2.35
The average length of an 11-year-old dugong should be 2.35.
I hope it helps!
Let dan's age be x then:-
james age is 3x and 2(x + 3x) is Pauls age so we have:-
x + 3x + 2*4x = 120
12x = 120
x = 10
so Dans age is 10 , James's age is 30 and Paul's age = 80
