According to algebra, we can break 12 into parts such that each X value when multiplied by 6 gives a total of 72. Thus, the 2nd option is correct.
Divide the quantity "12" into parts (the number of parts is not specified) and multiply each part by 6.
If you don't want to divide 12, the straight forward way is to simply multiply 12 by 6. 12 x 6 = 72
If we decompose 12 into 12 parts,
X₁, X₂, X₃, X₄, X₅, X₆, X₇, X₈, X₉, X₁₀, X₁₁, X₁₂
In this case X₁ represents the first unit of the number 12. X₂ represents the second unit of the number 12. X₁₂ represents the last unit of the number 12. Therefore, X₁ + X₂ + X₃ + X₄ + X5 + X₆ + X₇ + X₈ + X₉ + X₁₀ + X₁₁ + X₁₂ = 12
Each X value is the number 1. There are 12 locations and each case has its own identity. Multiplying each X value by 6 gives a total of 72.
According to algebra, we can break 12 into parts such that each X value when divided by 6 gives a total of 72. Thus, the 2nd option is correct.

In the triangle ABC, the side lengths, in order from the greatest to the least, are : AC > AB > BC.
We are given a triangle. The vertices of the triangle are A, B, and C. The measures of the angles ∠A, ∠B, and ∠C are 36°, 84°, and 60°, respectively. We need to arrange the side lengths in order from the greatest to the least.
The side lengths are proportional to their opposing angles in a triangle. It means that the side opposite the largest angle is the largest side, and vice versa. The angles arranged in descending order are : 84° > 60° > 36°. The angles arranged in descending order according to the vertices are : B > C > A. The order of the lengths of the opposite sides must be the same.
Hence, the side lengths, in order from the greatest to the least, are : AC > AB > BC.

I don't know what I'm suppose to do.
The equation of a line is y = mx +b
m = slope - which is equal to 1
x = x coordinate
b = y intercept (where the line hits the y axis)
y = y coordinate.
The point (2, 0) shows that when x = 2, y = 0. So we can plug that into the equation:
0 = 1(2) + b
0 = 2 + b
0 - 2 = 2 -2 +b
-2 = b
So the equation of the line is y = x - 2

What is Probability?
Probability gives us the information about how likely an event is going to occur
Probability is calculated by Number of favourable outcomes divided by the total number of outcomes.
Probality of any event is greater than or equal to zero and less than or equal to 1.
Probability of sure event is 1 and probability of unsure event is 0.
There are 10 numbers from 1 to 10
Number of favourable outcomes = 10 [tex]\times[/tex] 9 [tex]\times[/tex] 8

Find an expression for d so the line that passes through (a, b) and (c, d) has a slope of 1/2
Answer:
Step-by-step explanation:
In the book, they gave you the values of 'a', 'b', and 'c', and you're supposed to find the value of 'd'.
If you have two points on the line, then the slope of the line is
(the change in 'y') divided by (the change in 'x') .
If the two points are (a, b) and (c, d), then the slope of the line is
(d - b) divided by (c - a),
and you have to find the value of 'd' that makes that whole expression
equal to 1/2.
(d - b) / (c - a) = 1/2
Multiply each side by (c - a): (d - b) = 1/2(c - a)
Add 'b' to each side: d = 1/2(c - a) + b
If you know the values of 'a', 'b', and 'c', you can find the value of 'd'.

is m=-6 a solution to the inequality m less than or equal to -12
Answer:
No
Step-by-step explanation:
1) Write out the inequality to get a better understanding
m ≤ -12
From this we can see that m can be any number less than -12!
2) Find out possible solutions
As -12 is a negative number, any number less than it would have a larger absolute value.
Some examples of numbers less than -12 would be -15, -13, -36 ect.
HINTS:
It may be easy to confuse which number is greater or smaller than a negative number.
To make sure that we don't make a mistake, we can always put the numbers on a number line!
Any number to the left of it, is smaller, and any number to the right, is larger!

let, x denote the total number of hits,

one per week ⇒ 52 per year
therefore, rate = 52 per year

therefore by using the formula p (x = x) = (e^(-rate) × rateˣ) ÷ x! ; x = 0, 1, 2, ............( 2000 × 52)
p (x = 2) = (e⁻⁵² × 52ˣ) ÷ x! ; x = 0, 1, 2, ............104000

According to the company, 80% of lima bean seeds germinate.

To determine: the likelihood that exactly 14 seeds will germinate.
We use the binomial distribution to obtain the required probability when we need to track the success and failure of multiple objects (multiple Bernoulli trials)
Let X be the random variable that tracks the number of seeds that germinate out of a total of 20 seeds. The success rate is 80%, or 0.8.
Thus X ~ B(20,0.8)
The probability of X = x is given by:
P(X=x) = 20[tex]C_{x}[/tex][tex](0.8)^{x}[/tex][tex](1-0.8)^{20-x}[/tex]
