According to the order of operations, multiplication and division are performed before addition and subtraction.
... 8 - 12 ÷ 2 + 3
... = 8 - 6 + 3 . . . . . . 12÷2 = 6
... = 2 + 3 . . . . . . . . . 8-6 = 2
... = 5
Answer: 
Step-by-step explanation:
Given : Significance level : 
Sample size : n=85
Critical value : 
Sample mean : 
Standard deviation : 
The confidence interval for population mean is given by :-
Thus, the 95% confidence interval for the true mean cholesterol content, μ, of all such eggs =
Hence, we conclude that the true population mean of amount of cholesterol lies between 182.356 and 197.644.
Equation
Let the number = x
(2/3)x + x = 20 Change the x to thirds.
(2/3)x + 3/3x = 20 3/3 = 1 Now combine the like terms.
(2 + 3)/3 = 20 2/3 + 3/3 = 5/3
(5/3) x = 20 Multiply both sides by 3/5
(5/3)*(3/5)x = 20*3/5 Complete the multiplication on the right
x = 4 * 3 Combine
x = 12 Answer
(-4,5)(3,-9)
slope = (-9 - 5) / (3 - (-4) = -14 / (3 + 4) = -14/7 = -2
y = mx + b
slope(m) = -2
use either of ur points...(-4,5)...x = -4 and y = 5
now we sub and find b, the y int
5 = -2(-4) + b
5 = 8 + b
5 - 8 = b
-3 = b
so ur equation is : y = -2x + (-3) which can be written as : y = -2x - 3
