He mean potassium content of a popular sports drink is listed as 140 mg in a 32-oz bottle. Analysis of 20 bottles indicates a sa
mezya [45]

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 \mu 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 :H_0:\mu=140

Alternative hypothesis for two tail hypothesis has sign (≠).

i.e. Alternative hypothesis : H_1 : \mu\neq140

∴ The hypotheses for a two-tailed test of the claimed potassium content:

H0: μ = 140 mg vs. H1: μ ≠ 140 mg

⦁The areas of two similar triangles ABC and DEF are 100 cm2 and 144 cm2. If EF = 15 cmthen find the length of side BC.
ch4aika [34]

we know that


area larger triangle (DEF)=[scale factor]²*area smaller triangle (ABC)

solve for scale factor

scale factor=√[area larger triangle/area smaller triangle]

scale factor=√[144/100]------> scale factor=1.2


therefore

measure EF=scale factor *measure BC

solve for measure BC

measure BC=measure EF/scale factor-------> 15/1.2------> 12.5 cm


the answer is

measure BC is 12.5 cm
