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:

Step-by-step explanation:

Answer:
77% is greater than 3/5
3/5 = 0.60
Which as a percent is 60 % after moving the decimal to the right two places (multiply by 100)
Answer:
B. Add 2/5 to both sides
Step-by-step explanation:
Yuu have to add because it says subtract. inverse operations
We have been given diagram of a triangle. We are asked to write an expression that represents the distance between Seattle and San Francisco.
We will use law of cosines to solve our given problem.
, where a, b and c are sides corresponding to angle A, B and C.
Let the distance between Seattle and San Francisco be 'c' and
.
Using law of sines, we can set an equation as:

Upon taking square root in both sides, we will get:

Therefore, we can use the expression
can be used to find distance between Seattle, WA, and San Francisco, CA.
