three drivers competed in the same fifteen drag races. the mean and standard

deviation for the race times of each of the drivers are given.

driver a had a mean race time of 4.01 seconds and a standard deviation of 0.05

seconds

driver b had a mean race time of 3.96 seconds and a standard deviation of 0.12

seconds

driver c had a mean race time of 3.99 seconds and a standard deviation of 0.19

seconds.

a.

which driver had the fastest typical race time?

b.

which driver's race times were the most variable?

c.

which driver do you predict will win the next drag race? support your

prediction using the inean and standard deviation.

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18

c is the correct answer

step-by-step explanation:

step-by-step explanation:

*calories burned = (weight)(calorie factor)*

calories burned = 180 (0.65)

calories burned = 117

the calories he used up is 117, which is 65% of his weight.  

step-by-step explanation:

let's assume

number of candles set =x

price of of x candles =p(x)

we are given

a candle maker prices one set of scented candles at $10 and sells an average of 200 sets each week

so, we get point as (200,10)

he finds that when he reduces the price by $1, he then sells 50 more candle sets each week

so, we can find slope

now, we can use point slope form of line

now, we can plug values

we can use point

and find b

now, we can plug it back

and we get

now, we can find revenue

we know that

revenue = price*quantity

so, we get
