Answer:  A. We have 95% confidence that the limits of 13.05 Mbps and 22.15 Mbps contain the true value of the mean of the population of all data speeds at the airports.

Step-by-step explanation:

We know that a 95% confidence interval gives a range of data values that we are 95% sure that the true mean of the population lies in it.

Given : The results in the screen display are based on 95% confidence level.

Confidence interval : (13.046 , 22.15)

It means that we are 95% confident that the true value of population mean lies in (13.046 , 22.15) .

Thus, the statement that correctly interprets the confidence interval will be:

We have 95% confidence that the limits of 13.05 Mbps and 22.15 Mbps contain the true value of the mean of the population of all data speeds at the airports.

A cylinder has a volume of 540 cm cubed. if the height of the cylidner is 15 cm, find the radius.
Tamiku [17]
You should always remember that a cylinder consists of circles that are all over each other to form the height of the cylinder.
So the volume of the cylinder= the area of the surface circle* the height.
V=540=\pi r^2*h= \pi r^2*15
Then,
r^2= \frac{540}{15 \pi }
So, r= \sqrt{\frac{540}{15 \pi }}
radius is approximately 3.4cm

Val rented a bicycle while she was on vacation. She paid a flat rental fee of f dollars, plus $8.50 each day. The total cost at
damaskus [11]

The question is incomplete. Here is the complete question:

Val rented a bicycle while she was on vacation. She paid a flat rental fee of f dollars, plus $8.50 each day. The total cost at the end of her vacation was t dollars. Let d represent the number of days Val rented the bicycle. Write an equation representing the total cost at the end of her vacation.

Answer:

t=f+8.5d

Step-by-step explanation:

Given:

Flat rental fee = f

Variable fee per day = $8.50

Total cost at the end vacation = t

Number of days of her vacation = d

Using unitary method, we can find the variable fee for 'd' days.

1 day variable fee = $8.50

Therefore, 'd' days variable fee = 8.50d

Total cost at the end of her vacation can be obtained by adding the fixed rental fee and the variable fee obtained for the given number of days.

Now, total cost is given as:

Total cost = Flat rental fee + Variable fee

Substituting all the variables and framing above in the form of an equation, we get:

t=f+8.5d

Therefore, the equation representing the total cost at the end of her vacation is t=f+8.5d
