Answer:
A. g(x) = 1/3x + 1Step-by-step explanation:
The line has points:
(0, -3) and (1, 0)It has y-intercept b = -3 and a slope:
m = (0 + 3)/1 = 3The equation:
f(x) = 3x - 3It inverse is (let's call it g(x)):
x = 3y - 33y = x + 3y = 1/3x + 1g(x) = 1/3x + 1The slope of the inverse function is 1/3 and the y-intercept is 1
The graph reflecting this is A

Questions:
1. Write the fitted regression equation (30 points).
2. Write the estimated intercepts and slopes, associated with their corresponding standard errors (30 points).
3. Interpret each coefficient (40 points).
Answer:
Kindly check explanation
Step-by-step explanation:
Given the summary output :
_______ Coeff___ StdError__ t-stat
Intercept 1283.000_ 352.000 _ 3.65
X1 _____ 25.228 ____8.631
X2 _____0.861 _____0.372
General form of a multiple regression model:
Y = B1X1+B2X2 +E
The fitted regression equation is :
y = 25.228X1 + 0.861X2 + 1283
Intercept and slope corresponding to the standard error :
Intercept = 352
Slope 1 = 8.61 ; slope 2 = 0.372
'B' coefficient represents the change in the mean response, Y, per unit increase in a version predictor variable when all the other predictors are held constant.
B1 represents the change in the mean response, U, per unit increase in x1 when x2, x3, ..., xk are held constant
B2 represents the change in the mean response, U, per unit increase in x2 when x1, x3, ..., xk are held constant

1a. y = 2(11/5)^-x
2b. y= e^-2x
3c. y= 1/4e^x
9514 1404 393
Answer:
decaydecaygrowthStep-by-step explanation:
If the base of a positive exponential is greater than 1, the function is a growth function. If it is less than 1, the function decays.
Remember that a^-1 = 1/a, so a negative exponential can be transformed to a positive one.
__
1. y = 2(11/5)^-x = 2(5/11)^x . . . . 5/11 < 1, so decay
2. y = e^(-2x) = (1/e^2)^x . . . . 1/e^2 < 1, so decay
3. y = 1/4e^x . . . . e > 1, so growth
_____
e ≈ 2.71828 . . . an irrational number
A student usually saves $20 a month. He would like to reach a goal of saving $350 in 12 months. The student writes the equation
350 = 12(x + 20) to represent this situation. Solve the equation for x.
• Show your work or explain your answer.
Write your answer as a sentence that describes what the variable x represents.
Answer:
Step-by-step explanation:
350=12(x+20)
(divide both sides by 12)
29.1667=x+20
(subtract 20 from both sides)
x=9.16667
X (9.17) is the additional amount of money the student must save each month in order to reach his goal.

Answer:
x = 44.80
Step-by-step explanation:
Apply trigonometric function to find x.
Reference angle = 52°
Opposite side to reference angle = x
Adjacent side = 35
Apply TOA:
Tan 52° = Opp/Adj
Tan 52 = x/35
35 × Tan 52 = x
44.7979571 = x
x = 44.80 (to 2 decimal places)
The price of XYZ stock fluctuates widely. In January it closed at $3.50 but In February it Closed at $2.25. However at the end of March it shot back up to $5.00.
What was the average monthy change in the price of XYZ stock from january through march?
Answer:
$3.583
Step-by-step explanation:
Given the monthly stock prices :
January = $3.50
February = $2.25
March = $5.00
The average monthly change in price of XYZ stock from. JANUARY through MARCH is;
(January + February + March) / 3
Average monthly change :
(3.50 + 2.25 + 5.00) / 3
$10.75 / 3
= $3.583

A shelf is built on a wall, as shown below. What is the value of x?
(2x+1) + (3x-1)
Answer:
x = 18
Step-by-step explanation:
We need to find the value of x.
We know that the sum of angles of a triangle is equal to 180°. So, using this property,
2x+1+3x-1+90 = 180
2x+3x = 180-90
5x = 90
x = 18
So, the value of x is equal to 18.

Answer:
B: 6.0
Step-by-step explanation:
-3t^2+9t+54 = 0
This is the equation that needs to be solved
Divide both sides by -3
t^2 - 3t - 18 = 0
The factors of 18 are: (1 18) (2 9) (3 6)
3 - 6 = -3 and 3 x -6 = -18
So: (t + 3) (t - 6) = 0
t = -3, 6
It can't be negative so the answer is 6
