Step-by-step explanation:
Answer: (A) H0: μ = 140 mg vs. H1: μ ≠ 140 mg
Step-by-step explanation:
Usually null hypothesis represents the claim that the values associated to the groups being tested have no statistical difference but alternative hypothesis supports the claim that there is statistical difference.
Let 
be the population mean .
We are given that the mean potassium content of a popular sports drink is listed as 140 mg in a 32-oz bottle.
i.e. Null hypothesis :
Alternative hypothesis for two tail hypothesis has sign (≠).
i.e. Alternative hypothesis : 
∴ The hypotheses for a two-tailed test of the claimed potassium content:
H0: μ = 140 mg vs. H1: μ ≠ 140 mg
Answer:
2940
Step-by-step explanation:
Surface Area of a rectangular prism is 2(LW)+2(HW)+2(LH)
We have that the surface area is 1414 where L=c , H=20, W=7
Let's plug all of this in to solve for c:
2(LW)+2(HW)+2(LH)=1414
2(c*7)+2(20*7)+2(c*20)=1414
14c+280+40c=1414
54c+280=1414
54c=1414-280
54c=1134
c=1134/54
c=21
Now the volume of a rectangular prism is V=L*W*H
So plug in our values L=21, H=20, W=7
V=21*20*7=2940

Step-by-step explanation:
The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined. The range is the set of all valid y values. The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.
Interval Notation:
(-∞,∞)
Set-Builder Notation:
{x|x∈R}
The range is the set of all valid
y
values. Use the graph to find the range.
Interval Notation:
(−∞,∞)
Set-Builder Notation:
{y|y∈R}
Determine the domain and range.
Domain:
(−∞,∞),{x|∈R}
Range:
(−∞,∞),{y|y∈R}
Y=-3/5x -12
The y intercept is what you get when x = 0, which can't happen in this equation (can't divide by 0)
The x intercept is when -3/5x -12=0 or
3/5x = -12
3/-12 = 5x
3/-60 = x = -0.05
