I assume what you mean by this question is an equation like this:
1 + 2 x 3 + 4
Or,
3 x 4 + 6 /div 5
--
What you'd do:
1+2 x 3+4 First, add either 1+2 or 3+4 which is 3 & 7. then, youd multiply your answers as, 3 x 7 which is, 21.

Please ask if you have any questions
Lol, this sounds highly inaccurate. I have done orange squeezing myself. I can tell you, it's very disappointing. But for the sake of sayin it, let's do the math!!
Alright, so we know that FOUR large oranges makes SIX glasses of juice. It wants to know haw many glasses can be made when you increase the amount of oranges to SIX.
Well, that's simple. Set up an equation! 4/6=oranges over glasses.
6/x=oranges to unknown glasses.
Well, to solve this, we do exactly as the fractions imply. We divide. We need to know the orange-to-glass-ratio on a SMALLER scale.
So, simply take the denominator, and divide it by the numerator! 6/4=1.5
So, we know it takes 1 orange to make 1.5 glasses of juice now, 1/1.5
So, multiply both sides by 6, since that's how many oranges we have NOW.
1*6=6, 1.5*6=9
As a fraction, it's originally 6/x, but NOW it's 6/9
The answer is 6 oranges makes 9 glasses of juice

Answer:
a) See step by Step explanation
b) z(s) = 48.88
c) We reject H₀. The sample is not representative of American Adult Population
Step-by-step explanation:
From sample
sample mean . x = 49.28
sample standard deviationn s = 17.21
sample size n₁ = 4857
Population mean according to Census data
μ = 37.2
a) Test Hypothesis
Null Hypothesis . H₀ . x = μ = 37.2
Alternative Hypothesis Hₐ . x ≠ μ
b) We have sample size (4857) we can use normal distribution
z (c) for α = 0.01 α/2 . = 0.005 is from z-table . z(c) = 2.575
To calculate z(s) = ( x - μ ) / s /√n
z(s) = 12.08 * √4857 / 17.21
z(s) = 12.08* 69.64 / 17.21
z(s) = 48.88
z(s) > z(c)
We should reject H₀. The sample is not representative of American Adult population
