You are interested in determining which of two brands of batteries, brand a and brand b, lasts longer under differing conditions of use. one hundred fenix flashlights are fitted with brand a batteries and 100 olight flashlights are fitted with brand b batteries. each battery is used for 72 hours straight. the battery life is then measured for each battery, and the average battery life for the two brands is compared. what is wrong with this experimental design?

Examine the paragraph proof. which theorem does it offer proof for? prove jnm – nmi according to the given information in the image. jk | hi while jnm and lnk are vertical angles. jnm and lnk are congruent by the vertical angles theorem. because lnk and nmi are corresponding angles, they are congruent according to the corresponding angles theorem. finally, jnm is congruent to nmi by the transitive property of equality alternate interior angles theorem gorresponding angle theorem vertical angle theorem o same side interior angles theorem
