The savings plan balance after 2 years with an APR of 6% and monthly payments of $150 is approximately $3,814.79.

What are payments?

In compensation for products or services received or to fulfill a legal duty, payment is the voluntarily given exchange of money, its equivalent, or other valuables from one person to another. Frequently, the individual giving the money is referred to as the payer, while the person receiving it is referred to as the payee.

Assuming that the payments are made at the end of each month, we can use the formula -

[tex]A = PMT\Bigg[\frac{\big(1+\frac{APR}{n}\big)^{nY}-1}{\frac{APR}{n}}\Bigg][/tex]

where -

A = the savings plan balance after 2 years

PMT = the monthly payment ($150)

APR = the annual percentage rate (6%)

n = the number of compounding periods per year (12, since the payments are made monthly)

Y = the number of years (2)

Plugging in the values, we get -

[tex]A = 150\Bigg[\frac{\big(1+\frac{0.06}{12}\big)^{12 \times 2}-1}{\frac{0.06}{12}}\Bigg][/tex]

A ≈ $3,814.79

Therefore, value is obtained as $3,814.79.

Answer:

The correct answer you're looking for is either 85, or 68.07 (rounded)
The correct answer is if x is the hypotenuse or the most extensive length than its 85.
If x is one of the legs then 68.07 (rounded) is the correct answer.

Recommendation:

When trying to solve for a missing length you need to be sure whether it's just a leg or the hypotenuse, usually would be obvious in a picture as the sides attached to the 90º angle are usually legs and the one opposite of it is the hypotenuse.
Anywho below are the two different ways to get the answer.

Disclaimer:

There will be two answers that I will have given and I would suggest looking at the question to see which one it is, I am not only giving one possible answer. (Also very long answer, sorry!)

Note:

If messaged or commented on which numbers go on which side I'll be more than happy to confirm one answer.

Step-by-step explanation:

Figuring out only if X is Hypotenuse:

To solve for a hypotenuse you need to use the equation for the Pythagorean Theorem which states: [tex]a^{2} +b^{2}= c^{2}[/tex].

In this case, 36, and 77 are the two legs that make up this triangle.

We would insert these two numbers to replace a and b for when solving the equation.

Now you have [tex]36^{2}+ 77^{2}= c^{2}[/tex].

You then do the exponent operations for the terms that we know the values of and also add them up together to get this equation:
1296 + 5929 = 7725 or [tex]c^{2}[/tex].

After that, we'll make sure to add the terms on the first side and keep [tex]c^{2}[/tex] on the other and to also square root them giving this equation: [tex]\sqrt{7725} = \sqrt{c^{2}[/tex].

With that, your answer is 85 = X


Figuring out only if X is a Leg:

Figuring out only if X is Hypotenuse:
To solve for a leg you need to use the equation for the Pythagorean Theorem which states: [tex]c^{2}- b^{2}= a^{2}[/tex]

In this case, 36, is one of the two legs that make up this triangle while 77 is the Hypotenuse.

We would insert these two numbers to replace b and c when solving the equation.

Now you have [tex]72^{2} -36^{2} =a^{2}[/tex]

You then do the exponent operations for the terms that we know the values of and also add them up together to get this equation:
5929 - 1296 = 4633 or [tex]a^{2}[/tex]

After that, we'll make sure to subtract the terms on the first side and keep [tex]a^{2}[/tex] them on the other and also to square root them giving this equation:  
[tex]\sqrt{4633} =\sqrt{a^{2} }[/tex]

With that, your answer is 68.07 (rounded) = X

The correct inequality that represents the allowable measurements the bar can bend is | x - 4.5 | ≤ 0.1 , So correct option is E.

n mathematics, an inequality is a statement that indicates that two values are not equal. It is a relationship between two expressions that can be compared using inequality symbols such as < (less than), > (greater than), ≤ (less than or equal to), or ≥ (greater than or equal to).

For example, 5 < 10 is an inequality that indicates that 5 is less than 10. Similarly, x + 3 ≤ 8 is an inequality that indicates that the sum of x and 3 is less than or equal to 8.

Inequalities are used to express relationships between quantities that are not necessarily equal. They can be used to represent constraints, limits, or ranges of values. Inequality statements can be combined with other mathematical expressions, such as equations or inequalities, to create more complex mathematical models.

The correct inequality that represents the allowable measurements the bar can bend is:

| x - 4.5 | ≤ 0.1

This is because the average allowable bend is 4.5 cm with a margin of error of 0.1 cm, which means that the actual allowable bend can range from 4.4 cm to 4.6 cm. The absolute value inequality represents this range of values, with the center of the range being 4.5 cm.

Step-by-step explanation:

To find the measure of the central angle for the group that likes the student government program in a circle graph, we need to determine what proportion of the total number of students surveyed this group represents. We can do this by adding up the number of students who like the program and the number of students who think it is unnecessary, since these two groups represent the total number of students surveyed. Then we can divide the number of students who like the program by the total number of students surveyed and multiply by 360, which is the total number of degrees in a circle.

Total number of students surveyed = 190 + 135 + 220 = 545

Proportion of students who like the program = 190 / 545 ≈ 0.3486

So the measure of the central angle for the group that likes the program would be:

0.3486 x 360 ≈ 125

Therefore, the measure of the central angle for the group that likes the student government program would be approximately 125 degrees in a circle graph.

(Construir la tabla de distribución

de frecuencias e histograma de la altura (en cm) de 80 estudiantes de tercero medio.)

I think this is what you sayed?

For the following:

a) To determine the range of the heights, find the difference between the highest and lowest values.

Range = Highest value - Lowest value

The highest value is 188 cm, and the lowest value is 162 cm.

Range = 188 - 162 = 26 cm

b) The amplitude is the interval width of each class in the frequency table. To determine the amplitude, Know the number of classes. Assume to create 10 classes for the height data.

Amplitude = Range / Number of classes

Amplitude = 26 cm / 10 = 2.6 cm

c) To build the frequency table, to create the class intervals for the height data. Since the amplitude is 2.6 cm, choose the class intervals accordingly.

Set up the frequency table with 10 classes:

Class Intervals: (160 - 162.6], (162.6 - 165.2], (165.2 - 167.8], ..., (185 - 187.6], (187.6 - 190]

Next, count the number of data points falling into each class interval and calculate the absolute frequency (frequency), cumulative frequency, relative frequency, and percentage relative frequency.

The frequency table for the height data is attached.

In the frequency table, the "Cumulative Frequency" column shows the running total of frequencies, the "Relative Frequency" column shows the proportion of each class frequency to the total number of data points (80), and the "Percentage Relative Frequency" column shows the relative frequency expressed as a percentage.

Therefore, if a population of 150 mice triples in size every four months, there will be approximately 2,952,450 mice in the neighbourhood in 3 years.

Mathematicians use the unitary method to answer proportional relationship problems involving two or more quantities. It entails calculating the worth of one unit of one quantity in relation to another. For instance, let's say we are aware that 3 pencils cost $6. The following is how we can calculate the price of a solitary pen using the unitary method: The value of a single entity of the quantity "pen cost" in terms of the quantity "number of pens" was determined in this case. Once we are aware of a unit's worth, we can use that knowledge to determine the value of any other quantity that is related to it.

given

The population triples, or grows three times, in number, after four months. As a result, if we commence with 150 mice, the population will look like this after 4 months:

150 × 3 = 450 mice

The populace will triple once more after another 4 months (or 8 months from the beginning), becoming:

450 × 3 = 1350 mice

The populace will triple once more after another 4 months (or 12 months from the beginning), becoming:

1350 × 3 = 4050 mice

There is a pattern here: every four months, the populace triples. Therefore, we can determine how many times the population triples after three years (or 36 months) have passed:

36 months divided by 4 months per triple equals 9 triples.

the following group will exist after three years:

2,952,450 mice are equal to 150 × 39 (150 x 19,683).

Symmetry is a property of an object that describes how it appears identical after some transformation, such as reflection, rotation, or translation. It is an essential concept in mathematics, science, art, and many other fields.

There are several types of symmetry, including:

Reflectional symmetry (also called bilateral symmetry).
Rotational symmetry.

Translational symmetry.

According to the question:

a. The figure has rotational symmetry of order 2. This means that if we rotate the figure 180 degrees around its center, the figure will look exactly the same as it did before the rotation.

b. To achieve rotational symmetry of order 4, we need to add plates in such a way that the figure looks the same after a rotation of 90 degrees, 180 degrees, and 270 degrees around its center.
To achieve this, we can add three more plates to the figure, one in between each pair of existing plates, After adding these plates, the figure has rotational symmetry of order 4. We can see this by rotating the figure 90 degrees, 180 degrees, and 270 degrees around its center

First, we need to perform the multiplication operation within the parentheses, following the order of operations:

2⅓ × 1¼ = (7/3) × (5/4) = 35/12

Now, we can substitute the values in the expression:

3½ - (2⅓ × 1¼) + ⅗ = 7/2 - 35/12 + 3/5

To add or subtract fractions with different denominators, we need to find a common denominator. The least common multiple of 2, 12, and 5 is 60, so we can rewrite the fractions with this denominator:

7/2 - 35/12 + 3/5 = (210/60) / (2/2) - (175/60) / (12/12) + (36/60) / (5/5)
