Name a pair of overlapping congruent triangles in the diagram. State whether the triangles are congruent by SSS, SAS, ASA, AAS, or HL.
Given: LM≅LK; LN≅LJ
ΔLMJ and ΔLKN are congruent by SAS congruence postulate.
What is SAS and ASA congruence rule for triangles?
SAS : If two sides and the included angle of a triangle are congruent to two sides and the included angle of another triangle, then the two triangles are congruent.
ASA : If two angles and the included side of a triangle are congruent to two angles and the included side of another triangle, then the two triangles are congruent.
According to the given question:
The pair of overlapping congruent triangles in the diagram are:
ΔLMJ and ΔLKN
Now,
LM ≅ LK (Given)
LN ≅ LJ (Given)
∠LJM = ∠LNK (Angles opposite to equal sides are equal)
∴ ΔLMJ ≅ ΔLKN by SAS congruence of triangles

describe a procedure that you would use to localize the protein dynein in tissue sections of esophagus and trachea. indicate the results that you would expect from such an analysis.
Therefore, the five steps are taken to localize the protein dynein in tissue sections of the esophagus and trachea.
What is localization?Any procedure that involves moving, attaching to, or otherwise maintaining a cell, substance, or cellular entity in one place, like an organelle or protein complex. Substance localisation can also be accomplished through selective degradation.
In this case,
the steps that are done in order to localize the protein dynein in tissue sections of the esophagus and trachea are as follows:
1. Histoclear removes the medium to enable the labeling of the antibodies
2. to rehydrate the sample, add water.
3. Using BSA blocking solution after Triton X- 100, which ruptures membranes and makes antigens more accessible to antibodies
(4) Add the dynein antibody.
5. include a secondary antibody that is likewise peroxidase-active (adds specificity)

A manufacturer puts tires on two cars (four tires each). Each tire has a 10% probability of being flat. Assume the manufacturer puts four tires on one car first and then another four on the next car second. What's the probability that there is at least one car that has no working tires?
The probability that there is at least one car that has no working tires is given as follows:
0.0002 = 0.02%.
What is the binomial distribution formula?The mass probability formula, giving the probability of x successes, is of:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
The parameters are given by:
n is the number of trials of the experiment.p is the probability of a success on a single trial of the experiment.For each car, the parameters are given as follows:
p = 0.9, n = 4.
Hence the probability that a car has no working tires is given as follows:
P(X = 0) = (1 - 0.9)^4 = 0.0001.
Hence the probability that two cars have working tires is given as follows:
P(X = 2) = (1 - 0.0001)² = 0.9998.
The probability that at least one has no working tires is given as follows:
P(X < 2) = 1 - 0.9998 = 0.0002 = 0.02%.

A librarian wants to check a sample of books from the library to get an idea of how many need replacing.
Why might simple random sampling be a good way to do this?
He will not need a list of all the books
He will take longer if he checks all the books instead of checking a few
He will have a more representative sample if he chooses randomly
He will be able to choose whichever books he likes because it is random
The reason why simple random sampling will be a good way to do the selection of bad books is; Option C: He will have a more representative sample if he chooses randomly
What is the importance of simple random sampling?A simple random sample is defined as a randomly selected subset of a particular population. In this method of sampling, it will be noticed that each member of the population has an exactly equal chance of being selected.
The importance of simple random sampling is that it removes every form of bias as every member has an equal chance of being selected. Thus, it will give a good representation of what we want to research.
Now, in this case, since the librarian wants to check a sample of books from the library to get an idea of how many need replacing, it means that a random sampling method is good because;
He will have a more representative sample if he selects randomly as the definition earlier stated makes clear.

Alexandra and Maris are playing a game where they guess how many sides the regular polygon the other is holding has. Alexandra says her regular polygon has exactly 12 lines of symmetry. Maris says her regular polygon has an angle of rotational symmetry of 24°. How many sides does each regular polygon have?
The number of sides of Alexandra's regular polygon is 12.
The number of sides of Maris's regular polygon is 15.
What is a regulars polygon?
A regular polygon is denoted a area. The area bounded by equal length of arms. The angel between any two consecutive arms will same any other pair of consecutive arms.
The number of line of symmetry of a polygon is the same is the number of arm or sides of that polygon.
Thus the number of sides of a polygon that has 12 lines of symmetry is 12.
The angle of rotational symmetry of a polygon is 360°/n, where n is the number of arms.
Therefore,
Angle of rotational symmetry = 360°/n
Putting Angle of rotational symmetry = 24°:
24° = 360°/n
Multiply both sides by n
24n = 360
Divide both sides by 24:
n = 360/24
n = 15

OD. (f+g)(x) = 6x³+3x²-2-8
The composite function (f + g)(x) is (f + g)(x) = 9x² - x - 8
How to determine the composite functionFrom the question, we have the following parameters that can be used in our computation:
f(x)=3x²+42-6
g(x)=62-5²-2
Express properly
So, we have the following representation
f(x) = 3x² + 4x -6
g(x) = 6x² - 5x - 2
The composite function is then calculated as
(f + g)(x) = f(x) + g(x)
So, we have
(f + g)(x) = 3x² + 4x -6 + 6x² - 5x - 2

Answer: 5 4/15
Step-by-step explanation:
1 3/5 + 3 2/3 = 8/5 + 11/3
Find the common denominator (5 and 3) = 15
So 8/5 equals to 24/15 because if 5 x 3 = 15 , 8 must also multiply by 3.
11/3 equals to 55/15 because if 3 x 5 = 15 , 11 must also multiply by 5.
Thus 24/15 + 55/15 = 79/15
This is an improper fraction, so converting to mixed number:

Answer:
X = 4Step-by-step explanation:
To solve the equation 3(x+1) = 4x-1, we need to use the rules of algebra to isolate the variable "x" on one side of the equation and simplify the other side.
First, we can distribute the 3 on the left side of the equation to obtain 3x + 31 = 4x-1. This gives us 3x + 3 = 4x-1.
Next, we can subtract 3x from both sides of the equation to obtain 3 + 3 = 4x-1-3x. This simplifies to 3 = x-1.
Now we can add 1 to both sides of the equation to obtain 3+1 = x. This gives us the final solution x = 4.
Therefore, the solution to the equation 3(x+1) = 4x-1 is x = 4.
