After solving the equation we know that the resultant value of a is 14.

What are equations?

A mathematical statement that has an "equal to" symbol between two expressions with equal values is called an equation.

As in 3x + 5 Equals 15, for instance.

Equations come in a variety of forms, including linear, quadratic, cubic, and others. In this tutorial, let's study more about math equations.

The point-slope form, standard form, and slope-intercept form are the three main types of linear equations.

So, we have the equation:

5a + 3-3a = 31

No, solve the equation as follows for 'a:

5a + 3-3a = 31

5a - 3a = 31 - 3

2a = 28

a = 28/2

a = 14


Therefore, after solving the equation we know that the resultant value of a is 14.

what is the benefit of using a curve over a histogram?

Answers

The benefit of using a curve over a histogram is that, it is a useful tool for visualizing data distributions, curves provide a more detailed and flexible representation of the data and offer additional advantages in terms of resolution, flexibility, parametric modeling, and comparison.

Visualizing data is an essential aspect of understanding the underlying patterns and relationships. In data analysis, two popular ways of visualizing data are histograms and curves. While both of these visualization techniques serve the purpose of summarizing data, each of them has its unique benefits and limitations.

Resolution: One of the main benefits of using a curve over a histogram is that a curve provides a higher resolution representation of the data. A curve can capture finer details of the data distribution that might get lost in a histogram due to the binning process.

I have a regular polygon:

The sum of the interior angles is 1080 degrees. The length of each side is 5". The area is 160 square inches. What is the length of the apothem?

Do not label your answer.

Answers

Answer:

To find the apothem of a regular polygon, we can use the formula:

A = (ns^2)/(4tan(180°/n))

Where A is the area, n is the number of sides, s is the length of each side, and tan(180°/n) is the tangent of half of the central angle.

First, we need to find the number of sides of the polygon. To do this, we can use the formula for the sum of the interior angles of a polygon:

(n - 2)180° = 1080°

Solving for n:

n = 6

So the polygon has 6 sides.

Next, we can plug in the values we have into the formula for the apothem:

A = (6s^2)/(4tan(180°/6)) = 160

Expanding the right side:

A = (6s^2)/(4tan(30°)) = 160

Using the tangent identity:

A = (6s^2)/(4(√3/3)) = 160

Multiplying both sides by 4(√3/3) to isolate s^2:

4(√3/3)A = 6s^2

Expanding the left side:

4(√3)A/3 = 6s^2

Dividing both sides by 6:

2(√3)A/3 = s^2

Taking the square root of both sides:

s = √(2(√3)A/3)

Plugging in the value for A:

s = √(2(√3) * 160/3)

Calculating:

s = √(106.667) = 3.25

So the length of each side is 3.25 inches.

Finally, we can find the apothem using the formula:

a = s/2tan(180°/n)

Expanding the right side:

a = 3.25/2tan(30°)

Using the tangent identity:

a = 3.25/2(√3/3)

Dividing both sides by √3/3:

a = 3.25√3

Calculating:

a = 5.5

So the length of the apothem is 5.5 inches.

Answers

The initial amount a is 1250 and the rate of decay r is 0.865 (86.5%). When t = 3, the function h(t) = 1250(0.865)3 = 587.356. Rounded to the nearest tenth, the answer is 587.4.

To solve this exercise, you need to use the equation

h(t) = a(r)^t,

Where a is the initial amount and r is the rate of decay.

In this example,

a = 1250 and r = 0.865 (86.5%).

Plugging in t = 3 into the equation gives

h(t) = 1250(0.865)^3 = 587.356.

To round this to the nearest tenth, you need to look at the number to the right of the decimal point, which is the 6 in 587.356. Since the 6 is 5 or greater, you need to round the 587.356 up to 587.4.

What is an isosceles triangle?

An isosceles triangle in geometry is a triangle with two equal-length sides. Sometimes it is stated to have exactly two sides that are the same length, and other times it is stated to have at least two sides that are the same length, with the latter version including the equilateral triangle as an exception.

Given that the length of YZ = YX and ∠YZX = 25°.

There is an agreement between two sides. The base of an isosceles triangle refers to the third side of the triangle, which is unequal to the other two sides. The two angles that are opposite the equal sides line up perfectly.

According to the property of the isosceles triangle:

∠YXZ = ∠YZX = 25°

The sum of all angles of a triangle is 180°.

Therefore,

∠YXZ + ∠YZX + ∠XYZ = 180°

25° + 25° +  ∠XYZ = 180°

50° +  ∠XYZ = 180°

∠XYZ = 180° - 50°

Is height a ratio or interval?

Answers

Height is a interval - level variable typically in statistics.

Height is typically considered an interval-level variable in statistics. This means that height has a meaningful zero point, but the difference between two height measurements does not have a meaningful interpretation. For example, if one person is 6 feet tall and another person is 5 feet tall, the difference of 1 foot is meaningful, but the ratio of their heights is not.

In contrast, ratio-level variables have a meaningful zero point and the ratio of two values also has a meaningful interpretation.

Answers

The value of interior angle and the exterior angle will be 9, 140 degree.

Hence, option (a) is correct choice.

(a) 40, 140

An exterior angle of a regular polygon with 40 sides is equal to 360 divided by the number of sides, which is 360/40 = 9 degrees.

An interior angle of a regular polygon with 40 sides is equal to (180(n-2))/n,

where n is the number of sides,

which is (180(40-2))/40 = 140 degrees.

So the answer is: 9, 140.

(b) 140, 220

The exterior angle of a regular polygon with 40 sides is equal to 360 divided by the number of sides,

which is 360/40 = 9 degrees.

An interior angle of a regular polygon with 40 sides is equal to (180(n-2))/n,

where n is the number of sides, which is (180(40-2))/40 = 140 degrees.

So the answer is: 9, 140.

(c) 9, 171

The exterior angle of a regular polygon with 9 sides is equal to 360 divided by the number of sides, which is 360/9 = 40 degrees.

An interior angle of a regular polygon with 9 sides is equal to (180(n-2))/n,

where n is the number of sides, which is (180(9-2))/9 = 140 degrees.

So the answer is: 40, 140.

(d) 4.5, 175.5

This answer is incorrect.

The exterior angle of a regular polygon with 4.5 sides is not possible since the number of sides in a polygon must be a positive integer.

The size of one smaller cell : 2.5 x 10^-9 m.

The size of other larger ball: 1.5 x 10^3 times larger than first ball.

For the size of other larger ball:

Size = 2.5 x 10^-9 x 1.5 x 10^3

Size = 2.5 x 1.5 x 10^(-9+3)

Size = 3.75 x 10^6 m

Thus, the size of other larger cell is found as the 3.75 x 10^6 m , written in the scientific notation.

Step-by-step explanation:

Marna thinks that about 35% of her mail is junk mail. She gets about twice as much regular mail as junk mail. Is she correct?

Answers

Marna thinks is wrong. Thus Marna's think is incorrect.

What is the percentage?

A percentage is a number or ratio that can be expressed as a fraction of 100 in mathematics. If we need to calculate the percentage of a number, divide it by the whole and multiply by 100. As a result, the percentage denotes a part per hundred. The term % refers to one hundred percent. The symbol "%" represents it.

Given that Marna thinks that about 35% of her mail is junk mail.

Thus out of 100 emails, 35 emails are junk.

Thus the ratio of regular emails to junk mail is

100:35

= 20:7

Again given that she gets about twice as much regular mail as junk mail.

Assume that the number of junk mail is x.

Then the regular mail is 2x.

Thus the ratio of regular emails to junk mail is

2x:x

=2:1

The ratio  20:7 ≠ 2:1

What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.

Given is a pupil who scored 50 in his paper 1 exam got ill and missed paper 2.

Assume the equation of the line of best fit is of the form -

y = mx + c

Let {c} = 0

Now, for the point (1, 50), we can write -

50 = m

So, the equation will be of the form -

y = 50x

Now, for {x} = 2, we can write -

y = 100

Therefore, the marks in paper 2 would be 100.
