Answer: Conifers
Step-by-step explanation:
Conifers are the only living specie of gymnosperms and are cone bearing seed plants which are needle like and evergreen. Conifers produce pinecones and are common in the cold and boreal region. They are good timbers trees and are used for ornamental purposes. Conifers are the most important and diverse class of gymnosperms with about 588 living species. Examples are pines, cypresses, etc.
The volume of the box is 99 unit cubes.
<h3>What is the volume of the box?
</h3>
A cube is a three-dimensional object that has six faces, twelve edges and eight vertices. The length, width and height of a cube usually has equal dimensions. The volume of the box is a function of the dimension of the cubes in it and the number of layers.
Volume of a box = number of layers x amount of units
9 x 11 - 99 unit cubes

Y = 3x^2 - 3x - 6 {the x^2 (x squared) makes it a quadratic formula, and I'm assuming this is what you meant...}
This is derived from:
y = ax^2 + bx + c
So, by using the 'sum and product' rule:
a × c = 3 × (-6) = -18
b = -3
Now, we find the 'sum' and the 'product' of these two numbers, where b is the 'sum' and a × c is the 'product':
The two numbers are: -6 and 3
Proof:
-6 × 3 = -18 {product}
-6 + 3 = -3 {sum}
Now, since a > 1, we divide a from the results
-6/a = -6/3 = -2
3/a = 3/3 = 1
We then implement these numbers into our equation:
(x - 2) × (x + 1) = 0 {derived from 3x^2 - 3x - 6 = 0}
To find x, we make x the subject of 0:
x - 2 = 0
OR
x + 1 = 0
Therefore:
x = 2
OR
x = -1
So the x-intercepts of the quadratic formula (or solutions to equation 3x^2 - 3x -6 = 0, to put it into your words) are 2 and -1.
We can check this by substituting the values for x:
Let's start with x = 2:
y = 3(2)^2 - 3(2) - 6
= 3(4) - 6 - 6
= 12 - 6 - 6
= 0 {so when x = 2, y = 0, which is correct}
For when x = -1:
y = 3(-1)^2 - 3(-1) - 6
= 3(1) + 3 - 6
= 3 + 3 - 6
= 0 {so when x = -1, y = 0, which is correct}
Answer:
We have 10 sections, we can assume that the probability of hitting each of one of them is the same.
we have 9 grey slices and 1 white slice, then the probability of landing in a grey slice is equal to the number of grey slices divided by the total number of slices:
P(X) = 9/10 = 0.90
The probability of not landing in a grey slice is equal to the probability of landing in the white slice, this is:
P(not X) = 1/10 = 0.10
Also, when you have only two events, you can calculate this as:
P(not X) = 1 - P(X) = 1 - 0.90 = 0.10
Answer:
Step-by-step explanation:
Hi there!
Slope-intercept form: 
where <em>m</em> is the slope and <em>b</em> is the y-intercept (the value of y when x is 0)
<u>1) Plug in the slope (</u><u><em>m</em></u><u>)</u>
We're given that the slope is 
. In , replace <em>m</em> with :
<u>2) Determine the y-intercept (</u><u><em>b</em></u><u>)</u>
We're given the point (-9,4). Plug this point into the equation as 
and solve for <em>b</em>:
Subtract 
from both sides to isolate <em>b</em>:
Therefore, the y-intercept is . Plug this back into as <em>b</em>:
I hope this helps!
