An experiment is conducted to compare the maximum load capacity in tons​ (the maximum weight that can be tolerated without​ brea

king) for two alloys A and B. It is known that the two standard deviations in load capacity are equal at 7 tons each. The experiment is conducted on 30 specimens of each alloy​ (A and​ B) and the results are x overbarAequals65.6​, x overbarBequals60.6​, and x overbarAminusx overbarBequals5. The manufacturers of alloy A are convinced that this evidence shows conclusively that muAgreater thanmuB and strongly supports the claim that their alloy is superior. Manufacturers of alloy B claim that the experiment could easily have given x overbarAminusx overbarBequals5 even if the two population means are equal. Complete parts​ (a) and​ (b) below.

Which statement is true?
ioda

Answer:

Step-by-step explanation:

x-intercept -> when y = 0

f(x) x-intercept -> (1 , 0)

g(x) x-intercept -> (-1 , 0)

y-intercept -> when x = 0

f(x) y-intercept -> (0 , -1)

g(x) y-intercept -> (0 , 1)

The x-intercept of f(x) is greater than the x-intercept of g(x)

The y-intercept of g(x) is greater than the y-intercept of f(x)

So from the options, the answer is D. The x-intercept of f(x) is greater than the x-intercept of g(x)
