Answer:

$p =\frac{1}{6}$

Step-by-step explanation:

Given

$Polygons =\{Quadrilateral, Pentagon, Hexagon, Octagon, Nonagon, Decagon\}$

Required

Probability of assigning a nonagon

From the given set of polygons, there are 6 polygons in the set and 1 one of them is a nonagon

This means that:

$n = 6$ --- Total

$Nonagons = 1$

So, the probability, p is:

$p =\frac{Nonagons}{n}$

$p =\frac{1}{6}$

What percent of 150 is 9?

irga5000 [103]

One of the ways to find the answer is to find how much 1 percent of 150 is. To do that we just have to divide 150 by 100:

150 / 100 = 1.5

Now we can divide 9 by 1.5 to know how much percent of 150 it is:

9 / 1.5 = 6

Let's check it:

150 * 6% = 150 * 6/100 = 15 * 6/10 = 3 * 6/2 = 18/2 = 9

It's correct then :)

Use this expression to name each item. 7m3 + 6r2 – 3r - 8

Vitek1552 [10]

Answer:

In the given expression $7m^3 + 6r^2 - 3r - 8$

Variables = m, r

Coefficients = 7, 6 and -3

constant= -8

Step-by-step explanation:

We are given the expression $7m^3 + 6r^2 - 3r - 8$

We need to give variable, coefficients and constant.

Variable: The value of variable may change. It can be represented by x, y or any other letter

Coefficients: A numerical or constant quality that is placed with the variable. For example in 4x, 4 is coefficient

Constant: It is fixed value. It cannot be changed.

So, in the given expression $7m^3 + 6r^2 - 3r - 8$

Variables = m, r

Coefficients = 7, 6 and -3

constant= -8

the population of Bainville is 2000 the population is supposed to grow by 10% each year for the next 5 years how many people liv

Art [367]

Answer:

3000 people live in brainesville

Step-by-step explanation:

Population of brainville =2000

Grow rate of population per year =10%

10% of population =2000*10/100=200

Grow rate of 5 year=200*5=1000

After 5 year population of brainville is=2000+1000=3000

One of the two solutions to the equation $5x^2 - 11x - 36 = 0$ is $x = 4$. What is the other solution?

Firdavs [7]

Following are the calculation to the given equation:

Given:

$\to 5x^2 - 11x - 36 = 0$

one solution:

$x=4$

To find:

other solution=?

Solution:

$\to 5x^2 - 11x - 36 = 0\\\\\to 5x^2 - (20-9)x - 36 = 0\\\\\to 5x^2 - 20x+9x - 36 = 0\\\\\to 5x(x - 4)+9(x - 4) = 0\\\\\to (x - 4) (5x+9) = 0\\\\\to x - 4=0 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 5x+9 = 0\\\\\to x = 4 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 5x = -9\\\\\to x = 4 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ x = \frac{-9}{5}\\$

Therefore, another solution is " $-\frac{9}{5}$ ".
