given two points on a line and a third point not on the line, is it possible to draw a plane that includes the line and the third point?
Yes, it is possible to draw a plane that contains a line and a point not in the line.
A plane is a flat two-dimensional surface that extends to infinity. Planes are points (0-dimensional), lines (1-dimensional), and the 2-dimensional analogue of 3-dimensional space. The plane has zero thickness, zero curvature, infinite width, and infinite length. It's actually difficult to imagine an airplane in real life. All the flat surfaces of a cube or cuboid, the flat surface of paper are all practical examples of geometric planes.
In any dimensional Euclidean space, a plane is uniquely defined by either: Use three non-collinear points. Use points and lines that are not on this line. Use two different lines that intersect.

9+8n≤1 please help me with this
Answer:
n ≤ -1
Step-by-step explanation:
Inequality is a concept that refers to the unequal distribution of resources, opportunities, or status among individuals or groups. It can be measured in a number of ways, including income inequality, wealth inequality, and educational inequality.
For the Question:
Let's solve for 'n':
Given inequality:
[tex]\sf 9 + 8n \leq 1[/tex]
Subtract 9 from both sides:
[tex]\sf 9 + 8n -9 \leq 1 -9[/tex]
[tex]\sf 8n \leq -8[/tex]
Divide both sides by 8 (remember, since you're dividing by a negative number, the inequality sign flips):
[tex]\sf \dfrac{8n}{8} \leq \dfrac{-8}{8}[/tex]
n ≤ -1
So, the solution for 'n' that satisfies the inequality is n ≤ -1.
4 cards are drawn at random from a standard deck. find the probability that all the cards are hearts. find the probability that all the cards are face cards. note: face cards are kings, queens, and jacks. find the probability that all the cards are even. (consider aces to be 1, jacks to be 11, queens to be 12, and kings to be 13)
The probability that all the 4 cards are
1) hearts = 0.0026
2) face cards = 0.0018
3) even cards = 0.0179
In a standard deck of cards, we have:
Total number of cards= 52
1) The probability that all the cards are hearts.
In a standard deck of cards, we have:
the number of Hearts = 13
When a card is selected, the number of cards reduces by 1.
So, the probability that all the 4 cards are hearts is:
P1 = 13/52 × 12/51 × 11/50 × 10/49
P1 = 0.25 × 0.2353 × 0.22 × 0.2041
P1 = 0.0026
2) The probability that all the cards are face cards.
In a standard deck of cards, we have:
Face card = 12
When a card is selected, the number of cards reduces by 1.
So, the probability that all the 4 cards are face cards.
P2 = 12/52 × 11/51 × 10/50 × 9/49
P2 = 0.2308 × 0.2157 × 0.2 × 0.1837
P2 = 0.0018
3) The probability that all the cards are even.
In a standard deck of cards, we have:
Even cards = 20
When a card is selected, the number of cards reduces by 1.
So, the probability that all the 4 cards are even.is:
P3 = 20/52 × 19/51 × 18/50 × 17/49
P3 = 0.3846 × 0.3725 × 0.36 × 0.3469
P3 = 0.0179
Hence, the probability that all the 4 cards are even is 0.0179
Therefore, the probability that all the 4 cards are
1) hearts = 0.0026
2) face cards = 0.0018
3) even cards = 0.0179

Describe the similarities and differences between finding the slope of a linear equation from a graph that has x and y scales that are 1:1, and from a graph that has x and y scales that are not 1:1 (say your x and y scales are 2, 4, 6).
Using the concept of the slope of a linear function, we have that:
For a graph in a 1:1 scale, we can look at two consecutive values, y when x = a and y* when x = a + 1, and subtract y* by y. For a graph in another scale, we also do the same thing, but since the scale is not 1:1, we have to divide the subtraction of y* by y by the scale.What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.Given two points in the graph of a function, the slope is given by change in y divided by change in x, hence:
For a graph in a 1:1 scale, we can look at two consecutive values, y when x = a and y* when x = a + 1, and subtract y* by y. For a graph in another scale, we also do the same thing, but since the scale is not 1:1, we have to divide the subtraction of y* by y by the scale.More can be learned about linear function concepts at https://brainly.com/question/24808124

Each gallon costs $3.40. Bruno also buys a bag of ice
for $3.99. How much in total does Bruno spend at the
gas station to the nearest cent?
Answer:
Step-by-step explanation:
9.625 rounded is 10.
10 x $3.40 = $34
$3.99 rounded to the nearest cent is $4.
$34 + 4 = $38, so Bruno spends about $38 total.
The Rock Club members have collected 182 gems. How many did each
member collect if
a) Alice collected 1 more than 3 times what Cecil did.
b) Jaime collected 12 less than 3 times what Alice did.
c) Amir collected 10 less than Cecil.
d) Monte collected 5 more than Cecil.
How many gems didCecil collect?
How many gems did Alice collect?
How many gems did Jaime collect?
How many gems did amir collect
How many gems did Monte collect
Using a system of equations, the amounts of gems collected by each member is are given as follows:
Cecil: 13Alice: 40Jaime: 108Amir: 3Monte: 18.What is a system of equations?A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
For this problem, the variables are given as follows:
Variable x: Number of gems collected by Cecil.Variable y: Number of gems collected by Alice.Variable z: Number of gems collected by Jaime.Variable t: Number of gems collected by Amir.Variable w: Number of gems collected by Monte.They collected a total of 182 gems, hence:
x + y + z + t + w = 182.
Alice collected 1 more than 3 times what Cecil did, hence:
y = 3x + 1.
Jaime collected 12 less than 3 times what Alice did, hence:
z = 3y - 12 = 3(3x + 1) - 12 = 9x - 9.
Amir collected 10 less than Cecil, hence:
t = x - 10.
Monte collected 5 more than Cecil, hence:
w = x + 5.
Replacing everything in the first equation, we can solve for x as follows:
x + y + z + t + w = 182.
x + 3x + 1 + 9x - 9 + x - 10 + x + 5 = 182.
15x = 195
x = 195/15
x = 13.
Hence the other variables are:
y = 3(13) + 1 = 40.z = 9x - 9 = 9(13) - 9 = 108.t = x - 10 = 13 - 10 = 3.w = x + 5 = 13 + 5 = 18.Thus the amounts of gems collected by each member is are given as follows:

create an equation from the model that describes the relationship between the weights on each side of the scale
The algebraic equation that describes the relationship of the weights on both sides of the scale is: 2y + 3 = 4y + 2.
How to Create an Algebraic Equation?Using the weights on each side of the scale, we can create an algebraic equation that describes it.
Assume each weigh on the scale represents each side of an algebraic equation.
On left side, we can express the weights as: 2y + 3
On the right side, we can express the weight as: 4y + 2
Thus, expressing the relationship of the weights, we would have:
2y + 3 = 4y + 2
Thus, the algebraic equation that describes the relationship of the weights on both sides of the scale is: 2y + 3 = 4y + 2.

According to the given data:Tall and purple flower observed valve = 860
Dwarf and purple flower observed valve = 285
Tall and pink flower observed valve = 340
Dwarf and pink flower observed valve = 115
Total no. of flower = 860 + 285 + 340 + 115
