Duracell manufactures AA batteries for use in a wide variety of commercial products. The production line of Duracell is designed and operated in such a way that X, the voltage of any given battery produced on the line, is a normal random variable having a mean of 1.5V and a standard deviation of 0.01V.

a. What proportion of batteries has a voltage of 1.515 V or less?
b. What is the probability that the voltage of a produced battery exceeds 1.49 V?
c. What is the probability that the voltage of a produced battery is at least 1.48 V but no more than 1.52 V?
d. Find the battery voltage x such that 2.5% of the batteries produced have a voltage greater than x.
e. Find the battery voltage x such that 1% of the batteries produced have a voltage less than x.

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
