Five numbers have a range of 14. Four of the numbers are 20, 22, 31 and 25. Work out the two different possible values for the f

Pepsi [2]

Answer:

Step-by-step explanation:

Range is the difference between the highest and lowest values of a set of observations

Range = highest value - lowest value

the missing number can either by the highest value or the lowest value. this is because none of the numbers given when subtracted from each other would give a value of 14

let x = missing number

14 = x - 20

x = 20 + 14 = 34

14 = 31 - x

x = 31 - 14

x = 17

A hockey team plays in an arena with a seating capacity of 15,000 spectators. With the ticket price set at , average attendance

Goshia [24]

Answer:

Ticket price 11,5 $

R(max) = 132750 $

Step-by-step explanation:INCOMPLETE QUESTION

The ticket price is missing

We will assume 12 $

Let call x the decreasing number of the ticket price

The revenue is

R = ticket price * numbers of spectator

R(x) = ( 12 - x ) * ( 11000 + 1000*x ) for all 0 ≤ x ≤ 4 ( the seating capacity is 15000 )

R(x) = 132000 + 12000*x - 11000*x - 1000*x²

R(x) = 132000 + 1000*x - 1000*x²

Taking derivatives on both sides of the equatio we get:

R´(x) = 1000 - 2000x

R´(x) = 0 ⇒ 1000 - 2000x = 0

x = 1000/2000 ⇒ x = 0,5 $

We notice that R´´(x) < 0 then we have a maximum for x = 0,5

and the price is 12 - 0,5 = 11,5 $ for ticket

and the R(max) is

R(max) = 132000 + 1000*0,5 + 1000* (0,5)²

R(max) = 132000 + 500 + 250

R(max) = 132750 $

Given: △ABC, m∠C=90° m∠ABC=30°, AL ∠ bisector CL=6 ft. Find: LB

vlada-n [284]

For a better understanding of the solution given here please go through the diagram in the file attached.

To solve this question we will make use of the "Triangle Angle Bisector Theorem", which states that, "An angle bisector of an angle of a triangle divides the opposite side in two segments that are proportional to the other two sides of the triangle."

Thus, in our question, we will have:

$\frac{LB}{CL}= \frac{AB}{AC}$
