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
I'll do something similar to this, and I challenge you to do this on your own!
<something>-7=-34
Making that something equal to x, we have x-7=-34. Adding 7 to both sides using the addition property of equality (and to separate the x), we have
-34+7=x=-27
Good luck, and feel free to ask with any further questions!
Answer:
Part A) plot 1 and -2.5.
B) The opposite of 2 is -2. The only number that has its own opposite is 0. The first statement is false.
The opposite of 1.5 is -1.5, so the opposite of the opposite of 1.5 is equal to the opposite of -1.5, which is 1.5. The second statement is true.
Hope this helps sorry for not answering earlier
Answer:I can’t I sorry I don’t know this question
Step-by-step explanation:
Answer:
350:100
Step-by-step explanation:
By dividing 450 by 9 which is 7 + 2, both of the ratio numbers, and you get 50. Then you do 50 x 7, the first number, then 50 x 2, the second number, to get 350:100
