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, adn the average battery life for the two brands is comprared. what is wrong with this experimental design

q1 a person or thing situated away or detached from the main body or system. a cluster is a a mash of many things.

q2 do

step-by-step explanation:

i honestly dont know

a) at most means it can cost $12 or less

so the inequality sign would be ≤

you would then need to multiply the number of toppings by the 0.35 for each one and add it to the cost of the cheese pizza.

the equation would be 9.99 + 0.35x ≤ 12

b) using the above equation:

9.99 + 0.35x ≤ 12

subtract 9.99 from each side:

0.35x ≤2.01

divide both sides by 0.35:

x ≤ 2.01 / 0.35

x ≤5.74

at most you could have 5 toppings.

the 5 topping pizza would cost: 0.35 x 5 = 1.75 + 9.99 = $11.74
