The vertex angle of the isosceles triangle is 22°.
What is isosceles triangle?
A triangle with two equal sides is said to be isosceles. Also equal are the two angles that face the two equal sides. In other terms, an isosceles triangle is a triangle with two sides that are the same length.
We know that an isosceles triangle is composed of a vertex angle and two base angles. The base angles are congruent to each other. We also know that the sum of a triangle's angles is 180degrees.
Base angle = 3vertex angle+13.
=> 2base angle + vertex angle = 180°
=> 2(3 vertex angle +13)+vertex angle = 180°
=> 6 vertex angle+26+vertex angle = 180
=> 7 vertex angle = 180-26
=> 7 vertex angle = 154
=> vertex angle = 154/7 = 22°.
Hence the vertex angle of the isosceles triangle is 22°.

Sketch the region enclosed by the given curves. Decide whether to integrate with respect to x or y. Draw a typical approximating rectangle.
The area of the region enclosed by the given curves is 32 units2.
The region enclosed by the given curves is bounded by the equation y = x2 and y = 4. The region is a parabolic region and needs to be integrated with respect to y. A typical approximating rectangle for this region is shown in the diagram below.
The area of this region can be expressed as the integral:
A = ∫y=x2→4 y dx
This integral can be evaluated by splitting the integral into two parts: A = ∫y=x2→4 x2 dx + ∫y=x2→4 4dx
After evaluating the integrals, the area of the region is:
A = (1/3)x3 + 4x |y=x2→4
A = (1/3)(42) + 4(4 - 22)
A = 32
Therefore, the area of the region enclosed by the given curves is 32 units2.

What is the value of X
Answer:
A) 540
B) x = 115/3
Step-by-step explanation:
A) to find the sum of the interior angles of any gon, use this formula: 180(n-2); n = the number of sides of the gon you are given (ex. octagon will be n=8). Therefore, a pentagon will be: 180(5-2) = 540
B) To find x, we can add all the angles and make them equal to 540.
(3x+50) + (2x+60) + (3x-30) + 2x + 2x = 540
12x = 460
x = 115/3
C) Plug-in x for every angle

Work out the relative frequency of landing on yellow.
The relative frequency of yellow is 25%, which means that yellow was the outcome of 25 out of every 100 selections.
What is the relative frequency?
Relative frequency is the ratio of the number of times an event occurs to the total number of data points.
The relative frequency of landing on yellow is 100/400 = 0.25 or 25%.
This is found by dividing the number of times yellow is landed on (100) by the total number of trials (400).
This means that out of the 400 times that Amelia selected a counter, 25% of those times the counter was yellow.
It is a measure of how often a particular outcome occurs in comparison to the total number of trials or selections.
Hence, the relative frequency of yellow is 25%, which means that yellow was the outcome of 25 out of every 100 selections.

Step-by-step explanation:
The average of a set of numbers is defined as:
[tex]\dfrac{\textrm{sum of values}}{\textrm{number of values}}[/tex]
In this problem, we are shown a table where each row has a coupon value in the left column and the number of that coupon value in the right column (e.g., if we look at the top row, we can see there are 70 coupons each valued at $10).
So, the sum of values in this problem (i.e., the total number of dollars given out by the store in the form of coupons) is defined as the sum of the product of each row.
[tex]\textrm{sum of values} = (\$10 \times 70) + (\$20 \times 40) + (\$40 \times 20) + (\$60 \times 4) + (\$120 \times 2)[/tex]
[tex]\textrm{sum of values} = \$700 + \$800 + \$800 + \$240 + \$240[/tex]
[tex]\textrm{sum of values} = \$2780[/tex]
The number of values in this problem is just the sum of the numbers in the right column (i.e., the number of coupons given out).
[tex]\textrm{number of values} = 70 + 40 + 20 + 4 + 2[/tex]
[tex]\textrm{number of values} = 136[/tex]
Finally, to answer the problem, we can plug the two numbers that we just solved for into the formula for the average of a set.
[tex]\textrm{average savings} = \dfrac{\textrm{value of all tickets}}{\textrm{number of tickets}}[/tex]
[tex]\textrm{average savings} = \dfrac{\$2780}{136}[/tex]

The probability of a randomly selected adult having a rare disease for which a diagnostic test has been developed is 0.001. The diagnostic test is not perfect. The probability the test will be positive (indicating that the person has the disease) is 0.99 for a person with the disease and 0.02 for a person without the disease. The proportion of adults for which the test would be positive isA) 0.00099B) 0.01998C) 0.02097D) 0.02100
Adults make up 0.02100 of the probability for whom the test would be positive.
The proportion of adults for which the test would be positive can be calculated by multiplying the probability of a randomly selected adult having the rare disease (0.001) by the probability that the test will be positive for a person with the disease (0.99) and adding it to the probability that the test will be positive for a person without the disease (0.02).
0.001 x 0.99 = 0.00099
0.00099 + 0.02 = 0.02099
0.02099 = 0.02100 (rounded)
Therefore, the proportion of adults for which the test would be positive is 0.02100.The proportion of adults for which the test would be positive is 0.02100, which is calculated by taking into account the probability of a randomly selected adult having the rare disease (0.001) and the probability that the test will be positive for a person with the disease (0.99) and a person without the disease (0.02). This reflects how the test is not perfect and can sometimes give false positives or false negatives. The result of 0.02100 indicates that out of every 1000 adults, 2 of them will have a positive test result.

How many tables to be produced?Production is the act of combining a variety of material and immaterial inputs to create an output. In a perfect world, this output would be a good or valuable good or service for people to use. The three main production factors of land, labor, and capital are known as primary producers of goods or services.
These crucial inputs are not significantly altered by the output process or the end product, nor are they made a crucial component of it. In classical economics, materials and energy are regarded as secondary factors because they are byproducts of land, labor, and capital.

4. Calculate.[tex]\sf y-(4) =(\dfrac{1}{5} )(x+10 )\\ \\\\\sf y-(4) =(\dfrac{1}{5} )(x)+(\dfrac{1}{5} )(10)\\ \\ \\\sf y-(4) =\dfrac{1}{5} x+(\dfrac{10}{5} )\\ \\ \\\sf y-4 =\dfrac{1}{5} x+2\\ \\ \\\sf y-4+4 =\dfrac{1}{5} x+2+4\\ \\ \\\sf y =\dfrac{1}{5} x+6[/tex]
5. Verify the answer.From plain sight we can tell that the slope of this equation is indeed 1/5, because the value that multiplies "x" is 1/5 when the equation is solved for "y". Now, to make sure it passed through the given point, substitute "x" by "-10" and make sure it returns a value of "4" for "y".
[tex]\sf y =\dfrac{1}{5} (-10)+6\\ \\ \\\sf y =\dfrac{-10}{5}+6\\ \\ \\\sf y =-2+6\\ \\ \\y=4[/tex]
The answer is correct!
Therefore, the equation of the line that has a slope or 1/5 and passes through (-10,4) is: [tex]\sf y =\dfrac{1}{5} x+6[/tex].

What is the exponential function?
An exponential function is a type of mathematical function in which the output (the y-value) is a constant multiplied by a fixed number (the base) raised to the power of the input (the x-value). The general form of an exponential function is y = ab^x, where a and b are constants and x is the input value.
1 .To estimate f(1/3) using the graph points (0, 12) and (1, 0.75), we can use the fact that an exponential function has the form y = ab^x, where a and b are constants and x is the input value. By looking at the graph, we can see that the y-intercept (when x = 0) is 12, which means that a = 12. We can also see that the function passes through the point (1, 0.75), which means that f(1) = 0.75. Using this information, we can write the equation for the function as:
y = 12b^x
f(1/3) = 12b^(1/3)
Since we don't know the value of b, it's impossible to know the exact value of f(1/3) from the given information. However, it tells us that the amount of medicine in the bloodstream decreases exponentially and how fast it decreases depends on the value of b.
2. To find the equation that defines f, we can use the point (1, 0.75). We know that f(1) = 0.75, so we can substitute this into the equation we found earlier:
0.75 = 12b^1
0.75 = 12b
b = 0.0625
So, the equation that defines f is:
y = 12 * 0.0625^x
or
y = 0.75 * 0.0625^x
This equation tells us that the amount of medicine in the bloodstream decreases exponentially with time, with a rate determined by the value of b = 0.0625.

Prove that there exists a positive integer n < 10^6 such that 5^n has six consecutive zeros in its decimal representation
It has been proven that there exists a positive integer n < 10^6 such that 5^n has six consecutive zeros in its decimal representation. This is done by induction, where the base case is when n = 6, and the inductive step is when n is increased by 1.
We can prove this by induction.
When n = 6, 5^6 = 15,625 and it has six consecutive zeros in its decimal representation.
Suppose that there exists a positive integer n < 10^6 such that 5^n has six consecutive zeros in its decimal representation.
Let k = n + 1. Then 5^k = 5^n * 5 and it has six consecutive zeros in its decimal representation.
Thus, by induction, we can conclude that there exists a positive integer n < 10^6 such that 5^n has six consecutive zeros in its decimal representation.
