F is sometimes Positive and sometimes negative on the interval
2 1/14 should be your answer
Answer:
Skewed Left
Step-by-step explanation:
The shape of the sampling distribution of -x will match the shape of the parent population since the sample size is small (n=4<30, although it will be closer to normal than the parent population is.
Answer:
The length of the window is 35 inches.
Step-by-step explanation:
Perimeter of an object can be found using the general formula: P = 2W + 2L, where P = perimeter, W = width and L= length. Since both the width and perimeter of the window are given, we can plug these values into the formula to solve for the missing variable 'L': 112 = 2(21) + 2L, or 112 = 42 + 2L. We can then use inverse (opposite) operations to isolate the variable and solve. Whatever we do to one side of the equation, we do to the other. We will start by subtracting 42 from each side: 112 - 42 = 42 - 42 + 2L or 70 = 2L. Next, we divide both sides by 2 to solve for L: 70/2 = 2L/2 or L = 35. So, the final length of the window is 35 inches.
Equation of the circle:
(5)^2 = (x-2)^2 + (y-3)^2
see if any points work in the equation.
25 = (6-2)^2 + (0-3)^2
25 = 16 + 9
point (6,0) is on the circle
