I believe the correct answer from the choices listed above is the last option. The function that represents the total cost to build the dog house would be <span>c(p)=12p+65. Hope this answers the question. Have a nice day.</span>
Answer:
(f + g)(x) = x² + 4x - 4
Step-by-step explanation:
The statement (f + g)(x) is the same as f(x) + g(x). In other words, the question simply wants you to add the two functions together.
f(x) = 4x + 1
g(x) = x² - 5
(f + g)(x) <----- Original statement
f(x) + g(x) <----- Rewrite
(4x + 1) + (x² - 5) <----- Substitute the equations in f(x) and g(x)
4x + x² - 4 <----- Add 1 and -5
x² + 4x - 4 <----- Rearrange the terms
Answer:
Step-by-step explanation:
n = sample size = 5
a) Let us determine the sum
Now we can determine
The estimate b of the slope β is the ratio of and
The mean is the sum of all value divide by number of values
The estimate a of the intercept is
General least square equation;
replace alpha by a = 3 and beta by b = 0.67 in general least equation
y = a + bx
195.9 + 0.67x
b)
<em>Scatter plot is shown in the attached file</em>
x is on the horizontal axis
y is n the vertical axis
The degree of freedom of regression is 1
because we use one variable s predictor variable
The degree of freedom of error is the sample size n decrease by 2
Total df is equal to the sum of seperate degree of freedom dfR and dfE
total df = 1 +3 4
Total SS =Syy= 45007.2
SSE + Total SS = SSR
= 45007.2 - 43146.9296
= 1860.2705
