Data is collected to compare two different types of batteries. We measure the time to failure of 12 batteries of each type. Battery A: . Battery B: . Assume equal variances and that we calculated . Perform a .05 level test to determine if Battery B outlasts Battery A by more than 2 hours.

it is b)

hope this : )

step-by-step explanation:

she gotta workk that a 2

step-by-step explanation:

a - base

b - exponent

so,

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
