Answer:

55.74

Step-by-step explanation:

<em>Since the culture was tested and then the countdown started, you need to multiply the initial value by 3.5. Since it is tested once every 15 minutes, it will be tested two more times by the time 30 minutes is up; a total of 3 times tested.</em>

1.3 x 3.5 = 4.55

4.5 x 3.5 = 15.925

15.925 x 3.5 = 55.7375

The fuel economy of a car, measured in miles per gallon, is modeled by the function ƒ(s) = –0.009s2 + 0.699s + 12 where s repres

Kisachek [45]

Answer:

The maximum fuel economy of the car is 25.57225

Step-by-step explanation:

we are given

$f(s)=-0.009s^2+0.699s+12$

where

where s represents the average speed of the car, measured in miles per hour

So, we have to maximize f(s)

So, firstly we will find derivative

$f'(s)=-0.009*2s+0.699*1+0$

$f'(s)=-0.018s+0.699$

now, we can set it to 0

and then we can solve for s

$f'(s)=-0.018s+0.699=0$

$s=\frac{233}{6}$

To find maximum fuel economy , we can plug s into f(s)

$f(\frac{233}{6})=-0.009(\frac{233}{6})^2+0.699(\frac{233}{6})+12$

$f(\frac{233}{6})=25.57225$

So,

The maximum fuel economy of the car is 25.57225

The dot plot shows a random sample of the number of fish caught and released by 30 participants during a two-day fishing derby.

ratelena [41]

Answer:

The average of each day is 6 fishes

Step-by-step explanation:

Given

See attachment for dot plot

Required

Determine the true statement

For day 1, we have:

$Fis hes = 3 + 6 + 6 + 6 + 6 + 3$

$Fis hes = 30$

$Participants = 6$

The mean is:

$Mean = \frac{Fish es}{Participants}$

$Mean = \frac{30}{6}$

$Mean = 5$

For day 2, we have:

$Fis hes = 3 + 3 + 4 + 6 + 7 + 7$

$Fis hes = 30$

$Participants = 6$

The mean is:

$Mean = \frac{Fish es}{Participants}$

$Mean = \frac{30}{6}$

$Mean = 5$
