James is looking at a parallel circuit plan for lighting. there is a battery providing the power. there are switches labeled a, b,c, d that can be turned on to close the circuit. which switches must be on for light 1 to function?

B)A and B

Step-by-step explanation:

Switches A and B must be on for light 1 to light up. This diagram shows a parallel circuit that provides more than one way for the current to return to the power source.

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
