What value of will make the triangles similar by the similarity theorem?
Answers
As similarity theorem, the value of x that will make the triangles similar by SSS similarity theorem is 77.
Similarity theorem:
In math, similarity theorem refers the line segment splits two sides of a triangle into proportional segments if and only if the segment is parallel to the triangle's third side.
Given,
Here we need to find the t value of will make the triangles similar by the similarity theorem.
For example, we are told that the 2 triangles are similar by SSS theorem.
Here we know that, SSS means Side - Side -Side and it is a congruence theorem which states that the 3 corresponding sides of two triangles have same ratio, then we can say that the two triangles are congruent by SSS theorem
Therefore, in the triangles ,applying the SSS postulate gives;
=> x/35 = 44/20
Then by applying the multiplication property of equality, let us multiply both sides by 35 to get;
=> x = (44 * 35)/20
When we simplify this one then we get,
=> x = 77
Therefore, the value of x is 77.

The value u > -16 that makes the inequality 5u > -80 is true.
What is an inequality?In mathematics, "inequality" refers to a relationship between two expressions or values that are not equal to each other. To solve the inequality, you may multiply or divide each side by the same positive number, add the same amount to each side, take the same amount away from each side, and more. You must flip the inequality sign if you multiply or divide either side by a negative number.
Given:
We have the inequality,
5u > -80
To find the solution set of the inequality;
Divide by 5 to both sides,
5u/5 > -80/5
u > -16.
That means, the inequality is true for u > -16.
Therefore, the inequality is true for u > -16.

Consider a sample space that consists of five sample events E1, E2, E3, E4 and Es. (a) If P (E1) = P (E2) = 0.15, P (E3) = 0.4, and P (E4) = 2P (E5), calculate the P (E4) and P (E5). (4) (b) If P (E1) = 3P (E2) = 0.3, calculate the probabilities of the remaining simple events if you know that the remaining simple events are equally probable.
Answers
Answer:(a) P(E4) = 0.2 and P(E5) = 0.1.
Step-by-step explanation:
Let's start by assigning variables to the probabilities of E1, E2, E3, E4, and E5:
P(E1) = 0.15
P(E2) = 0.15 (same as P(E1))
P(E3) = 0.4
P(E4) = x (unknown)
P(E5) = 2x (twice the probability of E4)
We know that the sum of probabilities in a sample space must be equal to 1. So, we can set up an equation using the given information:
P(E1) + P(E2) + P(E3) + P(E4) + P(E5) = 1
Substituting the given probabilities:
0.15 + 0.15 + 0.4 + x + 2x = 1
Simplifying the equation:
0.3 + 0.4 + 3x = 1
0.7 + 3x = 1
3x = 0.3
x = 0.1
Therefore, P(E4) = 0.1 and since P(E5) is twice the probability of E4, we have P(E5) = 2(0.1) = 0.2.

Answers
Answer:
x = 11
z = 86
Step-by-step explanation:
8x + 6 and 10x-16 are vertical angles
Vertical angles are pairs of angles that are opposite each other and have the same vertex, or point of intersection. They are formed when two lines intersect at a point, and are always congruent, or of equal measure.
To solve this equation, we need to isolate the variable x on one side of the equation. To do this, we can start by subtracting 6 from both sides of the equation:
8x + 6 - 6 = 10x - 16 - 6
8x = 10x - 22
Now we can subtract 8x from both sides of the equation:
8x - 8x = 10x - 22 - 8x
0 = 2x - 22
To solve for x, we can add 22 to both sides of the equation:
0 + 22 = 2x - 22 + 22
22 = 2x
Finally, we can divide both sides of the equation by 2 to find the value of x: 22 / 2 = 2x / 2
x = 11
Therefore, the solution to the equation is x = 11.
Now that we have x, z is a supplementary angle to 8x + 6 (or you could do 10x - 16)
Supplementary angles are pairs of angles that add up to 180 degrees. They are formed when two lines intersect at a point, and the angles formed at the intersection are supplementary.
First plug in x, 8x + 6 = 8(11) + 6 = 88 + 6 = 94
180 - 94 = z
z = 86

the missing angle in the triangle on the right is
180° - (74 + 55)° = 180° - 129° = 51°
the 2 triangles have 3 pairs of congruent angles and are therefore congruent.
Corresponding sides and angles are then congruent

(This means that addition does not distribute over the dot product.) Explain the problem that arises. morkol
Answers
a) The dot product is not associative because the dot product of a scalar and a vector does not yield a valid dot product.
b) Addition does not distribute over the dot product, as shown by the example (a + b) • (a + c) ≠ a + (•).
a) The dot product is not associative because it is defined as the product of the magnitudes of two vectors and the cosine of the angle between them. Mathematically, the dot product of two vectors a and b is given by a • b = |a| |b| cos(θ), where θ is the angle between the vectors.
In the expression (5 • 2) = (a • b) • c, we can rewrite it as 10 = (a • b) • c. However, the dot product of a and b, denoted as a • b, is a scalar quantity, while the dot product of (a • b) and c would be a vector quantity. Therefore, it is not possible for a scalar quantity to be equal to a vector quantity, and hence the dot product is not associative.
b) Addition does not distribute over the dot product, as shown by the example a + (•) = (a + b) • (a + c). Let's consider the vectors a = (1, 0) and b = (0, 1). The expression on the left side becomes a + (•) = a + (a • b) = a + (1) = (2, 0). On the right side, we have (a + b) • (a + c) = (a + b) • (a + b) = (a • a) + (a • b) + (b • a) + (b • b) = 1 + 0 + 0 + 1 = 2.
As we can see, the result on the left side is (2, 0), while the result on the right side is 2. These two results are not equal, indicating that addition does not distribute over the dot product.
The problem arises because the dot product is a scalar operation, while addition of vectors is a vector operation. The dot product combines the magnitudes and angle between vectors, while addition of vectors combines their corresponding components. Therefore, the two operations do not interact in a distributive manner.

an unnormalized relation is a table that has more than one row.
Answers
An unnormalized relation refers to a table in a relational database that contains more than one row. This means that there are duplicate rows in the table, which violates the rules of normalization.
Normalization is a process in database design that aims to eliminate data redundancy and ensure data integrity. It involves breaking down a database into multiple tables and defining relationships between them. By doing so, we can efficiently store and retrieve data while minimizing inconsistencies.
In an unnormalized relation, duplicate rows can lead to various problems. For example, it can result in data inconsistencies, as updating one instance of a row may not reflect changes in other duplicate rows. Additionally, it can cause unnecessary storage and maintenance overhead.
To normalize an unnormalized relation, we need to identify the functional dependencies in the table and create separate tables for related data. This helps organize the data and reduces redundancy.
In summary, an unnormalized relation is a table in a relational database that has duplicate rows. It is important to normalize such relations to ensure data integrity and efficiency.

Find the p-value for this test based on the following sample information. (You may find it useful to reference the appropriate table: z table or t table)
a. xยฏxยฏ = 380; s = 39; n = 18
Answers
The p-value for this test is 0.012, which is the probability of observing a sample mean as extreme as 380 (or more extreme) if the null hypothesis were true.
If the significance level of the test was α = 0.05, for example, we would reject the null hypothesis since the p-value (0.012) is less than the significance level.
To find the p-value for this test, we first need to determine the appropriate test statistic. Since we do not know the population standard deviation, we will use a t-test. The test statistic is calculated as:
t = (X - μ) / (s / √n)
Where X is the sample mean, μ is the null hypothesis population mean, s is the sample standard deviation, and n is the sample size.
In this case, the null hypothesis might be that μ = 400 (for example, if we were testing whether the mean weight of a certain type of fruit was 400 grams). Using the given sample information, we can calculate the t statistic as:
t = (380 - 400) / (39 / √18) = -2.82
Next, we need to find the corresponding p-value from the t-distribution table. Looking at the table with 17 degrees of freedom (since n - 1 = 18 - 1 = 17), we find that the p-value for a two-tailed test with a t-value of -2.82 is approximately 0.012.
