Answer:
A
Step-by-step explanation:
-x + 2y = 8
5x + 2y = -4
+ x. -2y. -8
6x = -12
÷6. ÷6
x = -2
5(-2) + 2y = -4
-10 + 2y = -4
+10. +10
2y = 6
÷2. ÷2
y = 3
Answer:
(20.532 , 21.468)
Step-by-step explanation:
Enter data into L₁
CL= 0.95
df= 3
Distribution: xbar ~ t₃
Calculator commands (for TI only): [Stat],[TESTS],[TInterval],[Data],(List: L₁),(Freq:1),(C-Level:0.95),[Calculate]
Confidence interval (20.532,21.468)
We can conclude that the true population mean for bags of potatoes labeled 20.0 pounds is between (20.532,21,468) with a 95% confidence level.
Answer:
y = 0
Step-by-step explanation:
The given sinusoidal equation is
The general form of the sin function is presented as follows;
y = A·sin(B·(x - C)) + D
Where;
A = The amplitude
The period, T = 2·π/B
The frequency, f = B/2·π
C = The horizontal shift
D = The vertical shift
By comparison with the given sine function, we have;
The amplitude, A = 2
The frequency, f = B/2·π = π/2/(2·π) = 1/4
The frequency, f = 1/4 Hz
C = The horizontal shift = 3/(π/2) = 6/π
The vertical shift, D = 0
Given that the mid line of the parent function, sin(x), is the line y = 0, and that the vertical shift is 0, the midline of the function, , is therefore, the line;
y = 0.
