Answer:

B. 0

Step-by-step explanation:

ax² + bx + 1 = 0

discriminant = b² - 4ac

4x² - 20x + 25

a = 4

b = -20

c = 25

b² - 4ac = (-20)² - 4(4)(25) = 400 - 400 = 0

Answer: B. 0

Your client has asked you to evaluate customers attending the games for a professional football team. The stadium is interested

ZanzabumX [31]

Answer:

Number of spectators who leave the stadium before 180 minutes

This data would show if spectators only come to the stadium and stay until the end of the game when their favorite teams are playing

Number of customers/spectators attending the last 100 matches

This data will help the stadium know the current trend ( either increasing of decreasing ) number of the spectators who visit the stadium

The data can be collected via the exit time entries at the exit gate of the stadium

history of ticket sold over the last 100 matches

we have to conduct a hypothesis test assuming that a spectator watches a match for more than 180 minutes with an assumed standard deviation

we can also use regression analysis and line of best fit to check for the trends

Step-by-step explanation:

Aim : The Aim of the stadium is Increasing revenue generated in the stadium and some of the ways to achieve such is by taking specific data as regards the customers/spectators who visit the stadium

The type of data that could be collected from the fans to be used in multiple regression model:

Number of spectators who leave the stadium before 180 minutes

This data would show if spectators only come to the stadium and stay until the end of the game when their favorite teams are playing

Number of customers/spectators attending the last 100 matches

This data will help the stadium know the current trend ( either increasing of decreasing ) number of the spectators who visit the stadium

How can the data be collected

The data can be collected via the exit time entries at the exit gate of the stadium

history of ticket sold over the last 100 matches

how to apply the data

we have to conduct a hypothesis test assuming that a spectator watches a match for more than 180 minutes with an assumed standard deviation

we can also use regression analysis and line of best fit to check for the trends

A maritime flag is shown. What is the area of the shaded part of the flag? Explain

Rom4ik [11]

Answer:

$Area = 72in^2$

Step-by-step explanation:

Your question is incomplete without an attachment (See attachment)

Required

Determine the area of the shaded part

From the attachment;

Assume that the shaded portion is closed to the right;

Calculate the Area:

$Area_1 = Length * Width$

$Area_2 = 8in * (6in + 6in)$

$Area_2 = 8in * 12in$

$Area_1 = 96in^2$

Next;

Calculate the Area of the imaginary triangle (on the right)

$Area_2 = \frac{1}{2} * base * height$

$Area_2 = \frac{1}{2} * (6in + 6in) * 4in$

$Area_2 = \frac{1}{2} * 12in * 4in$

$Area_2 = \frac{1}{2} * 48in^2$

$Area_2 = 24in^2$

Lastly, calculate the Area of the Shaded Part

$Area = Area_1 - Area_2$

$Area = 96in^2 - 24in^2$

$Area = 72in^2$

Hence,

The area of the shaded part is 72in²
