Answer:
80 tickets
Step-by-step explanation:
Given the profit, y, modeled by the equation, y = x^2 – 40x – 3,200, where x is the number of tickets sold, we are to find the total number of tickets, x, that need to be sold for the drama club to break even. To do that we will simply substitute y = 0 into the given the equation and calculate the value of x;
y = x^2 – 40x – 3,200,
0 = x^2 – 40x – 3,200,
x^2 – 40x – 3,200 = 0
x^2 – 80x + 40x – 3,200 = 0
x(x-80)+40(x-80) = 0
(x+40)(x-80) = 0
x = -40 and x = 80
x cannot be negative
Hence the total number of tickets, x, that need to be sold for the drama club to break even is 80 tickets
Answer:
Area of living room
= 20(x+5)
= 20x +100
Area of dining room= 20x
Total area
= 20x +100 +20x
= 40x +100
Total perimeter (after wall is removed)
= 2(20) + 2( x+x+5)
= 40 + 2(2x+5)
= 40 +4x +10 (expand)
= 4x +50 (simplify)
Step-by-step explanation:
Area of rectangle= length × breadth

15 minutes??
I guess?
Step-by-step explanation:
Im really not sure
There's a pattern!!
You just need to count how many numbers passed by!
Clear?
<span>Standard deviation shows the distribution present in a set. Range can be used to approximate this property.
Therefore, Set b (100, 140, 150, 160, 200 10, 50, 60, 70, 110) has the largest standard deviation because it has a range of 190 (i.e. 200 - 10)</span>
The mean is 10,724.28.
Explanation:
The mean is all of the values divided by the number of values there are.
So what you have to do is add all of the numbers and divide it by the amount of numbers there are.
10,150+10,211+10,424+10,769+10,884+11,155+11,477= 75,070.
Since there are 7 numbers, divide 75,070/7 and you get your mean, which is 10,724.28 rounded.
