I’m not that sure if the numbers you provided are the ones I am supposed to be adding or the x’s in the graph but here’s an answer for both

Numbers: 150
X:10

If I didn’t understand what to add, please let me know

The x’s represent just the people, and because the bottom line only represents time it doesn’t affect the amount of people.

Let, the length be l and breadth be b.

So, 2(l + b) = 26

Or, l + b = 13

Or, l = 13 - b

So, we may write like this,

Area = l * b

Or, l * b > 30

Or, l (13 - l) > 30

Or, 13l - l^2 > 30

Or, l^2 - 13l + 30 > 0

Or, l^2 - 3l - 10l + 30 > 0

Or, l(l - 3) - 10(l - 3) > 0

Or, (l - 3)(l - 7) > 0

Or, l - 7 > 0

Or, l > 7.

Now, putting the value of l,

We get, l * b > 30

Or, 7 * b > 30

Or, b > 30/7

➡️ Therefore, we get,

Length > 7

Breadth > 30/7

That's it..

When you solve this equation, you can plug in 2x + 10 for y, so you would have 2x + 10 = 2x +4. When you solve for x, you notice that you end up getting 10 = 4, which is impossible!

There are NO solutions for this, because 10 will never equal 4.

The slope of the first line is 2.

The slop of the second line is also 2.

The lines ARE parallel- they have the same slope!

They do not have the same y-intercept, one of them crosses at y=4, and the other crosses at y=10.

Since the lines are parallel, they will never cross, which is why there are no solutions for this equation.

Hope this helps! :)

To determine what percentage of 376 teachers at a university were female, Ryan randomly selected 14 teachers. He then collected

Kipish [7]

Answer:

a)There are 14 teachers in Ryan's sample, and 362 teachers in the population.

Step-by-step explanation:

Population:-

The totality of observations with which we are concerned, whether this number be finite or infinite is called population.

Given data population is 376 teachers at a university were female'

Sample:-

A sample is a subset of a Population

sample of given data = 14teachers

The percentage of 376 teachers at a university were female, Ryan randomly selected 14 teachers.

$p = \frac{14}{376} = 0.0372$ = 3.72%
