Answer:

38 people have a membership.

Step-by-step explanation:

That's because the bottom row shows how many years they've had the membership.

And the y axis shows how many people or the frequency of people having the membership for that amount of years.

So its a bar graph that shows you how many of the members have had the membership for a set amount of years.

So all you have to do is add up each column,

0-2 years = 6 people

2-4 years = 8 people

4-6 years = 10 people

6-8 years = 8 people

8-10 years = 6 people

6 + 8 + 10 + 8 + 6 = 38

What is an equation of the line that passes through the points (-3,-1) and

NARA [144]

The equation of line that passes through the points (-3,-1) and

(-6,3) is:

$y=-\frac{4}{3}x-5$

Step-by-step explanation:

Given points are:

(-3,-1) =(x1,y1)

(-6,3)=(x2,y2)

The slope-intercept form of equation of line is:

$y=mx+b$

We have to find the slope first

$m=\frac{y_2-y_1}{x_2-x_1}\\=\frac{3-(-1)}{-6-(-3)}\\=\frac{3+1}{-6+3}\\=\frac{4}{-3}$

Putting the value of slope in the slope intercept form

$y=-\frac{4}{3}x+b$

To find the value of b, putting the point (-3,-1) in the equation

$-1=-\frac{4}{3}(-3)+b\\-1= 4+b\\b=-4-1\\b=-5$

Putting the values of b and m

$y=-\frac{4}{3}x-5$

The equation of line that passes through the points (-3,-1) and

(-6,3) is:

$y=-\frac{4}{3}x-5$

Suppose that each day a company has fixed costs of 400 dollars and variable costs of 0.8x+1420 dollars per unit, where x is the

Bess [88]

Answer:

Step-by-step explanation:

Given that a company fixed costs are 400 dollars

and variable cost = $0.8x+1420$ per unit and x the no of units produced

Selling price = $1500-0.25x$ per unit

a) Break even units

At break even units selling price = variable cost

$1500-0.25x=0.8x+1420\\1.05x = 80\\x=76.19~76$

Break even units = 76

b) Revenue = Sales - total costs

= $x(1500-0.25x)-(x)(0.8x+1420)-400\\= 1500x-0.25x^2-0.8x^2-1420x-400\\= -1.05x^2+80x-400$

Use derivative test to get max revenue

R'(x) = $-2.10x+80$

R"(X) <0

So maximum when I derivative =0 or when

$x=38.10$

x=38

c) price when x =38 is

$P = 1500-0.25(38)\\=1490.5$

A parallelogram has an area of x2 + 9x - 36.

malfutka [58]

Answer:

Step-by-step explanation:

Please use " ^ " to indicate exponentiation:

A = x^2 + 9x - 36. This factors into A = (x + 12)(x - 3). We can assume that the length of the parallelogram is x + 12 and that the width is x - 3.

Note that if x = 3 the area becomes zero. So: x must be greater than 3, so that the (x - 3) factor is positive.

Example: If x = 4, then the dimensions of the parallelogram are 4 + 12, or 16, and 4 - 3, or 1.
