Step-by-step explanation:

A box that contains two times as many cubes as a box that is 2 by 3 by 5 can have dimensions of 2 by 3 by 10.

a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.

A box that is 2 by 3 by 5 has a total of 2 x 3 x 5 = 30 cubes. To build a box that will hold twice as many cubes, we need to find the dimensions that will give a total of 60 cubes.

Let's assume the dimensions of the new box are x, y, and z. Then, we have:

xyz = 60

We can express one of the variables in terms of the other two.

z = 60 / (xy)

Substitute this in above equation.

xy60/xy=60

60=60

This is true for any values of x and y, as long as z is calculated as z = 60 / (x y).

There are infinitely many solutions for the dimensions that will give a box with a total of 60 cubes.

set of dimensions that satisfies the condition is x = 2, y = 3, and z = 10.

Hence, a box that contains two times as many cubes as a box that is 2 by 3 by 5 can have dimensions of 2 by 3 by 10.

Complete Question

Scores of an IQ test have a bell-shaped distribution with a mean of 100 and a standard deviation of 11. Use the empirical rule to determine the following:

a. What percentage of people has an IQ score between 89 and 111?

b. What percentage of people has an IQ score less than 89 or greater than 111?

c. What percentage of people has an IQ score greater than 133?

Answer:

a) 68%

b) 32%

c) 0.15%

Step-by-step explanation:

The Empirical rule formula:

1) 68% of data falls within 1 standard deviation from the mean - that means between μ - σ and μ + σ .

2)95% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ .

3) 99.7% of data falls within 3 standard deviations from the mean - between μ – 3σ and μ + 3σ .

a. What percentage of people has an IQ score between 89 and 111?

Using :μ - σ , μ + σ

μ = Mean = 100

σ = Standard deviation = 11

μ - σ

100 - 11 = 89

μ + σ

100 + 11 = 111

Hence, from the above calculation, this data falls within 1 standard deviation from the mean - that means between μ - σ and μ + σ . Hence, it satisfied the first rule in the Empirical formula.

Therefore, 68% of data falls within 1 standard deviation from the mean.

b. What percentage of people has an IQ score less than 89 or greater than 111?

Using :μ - σ , μ + σ

μ = Mean = 100

σ = Standard deviation = 11

μ - σ

100 - 11 = 89

μ + σ

100 + 11 = 111

Hence, from the above calculation,68% of this data falls within 1 standard deviation from the mean - that means between μ - σ and μ + σ . Hence, it satisfied the first rule in the Empirical formula.

But we are told to find the percentage of people that score less than 89 and above 111

100 - 68 = 32%

c. What percentage of people has an IQ score greater than 133?

We apply the third rule of the Empirical rule formula

99.7% of data falls within 3 standard deviations from the mean - between μ – 3σ and μ + 3σ .

μ = Mean = 100

σ = Standard deviation = 11

μ + 3σ

100 + 3(11)

100 + 33

= 133

Since we are to find the percentage greater than 133

Hence: 100 - 99.7%

= 0.3%

The percentage greater than 133(the right hand side)

= 0.3%/2

= 0.15%

The values of {m} that is greater than 4.6 represent the solution of the given inequality.

An inequality is used to compare two or more expressions or numbers.

For example -

2x > 4y + 3

x + y > 3

x - y < 6

The given inequality is -

5m - 7 > 16

Adding 7 on both sides, we get -

5m - 7 + 7 > 16 + 7

5m > 23

m > 23/5

m > 4.6

Therefore, the values of {m} that is greater than 4.6 represent the solution of the given inequality.

Mathematical symbols used to represent quantities or values include numbers. They are employed in the measurement, comparison, addition, subtraction, multiplication, and division processes in mathematics. According to their qualities and properties, numbers can be categorized into a variety of groups, including natural numbers, whole numbers, integers, rational numbers, irrational numbers, real numbers, and complex numbers. There are specific properties and guidelines for mathematical operations for each group of numbers. Mathematics depends on numbers, which are also utilized in many other disciplines, including science, engineering, economics, and statistics.

The number of greetings exchanged between the host and the other mothers and daughters must be counted first. Since there is only one host, the number of mother-daughter pairs is 20 - 1 = 19. There are thus a total of 38 greetings, 19 between the host and the other moms, and 19 between the host and the other daughters.

The number of pleasantries exchanged between the guest mums and everyone else must next be tallied. The host, the other mothers, and the daughters must all be greeted, making a total of 20 - 1 = 19 guest mothers. Thus, each host mother must extend 1 + 19 + 20 = 40 greetings. There will be 760 greetings exchanged between the guest mothers and everyone, or 19 x 40.

The number of pleasantries exchanged between the mothers and the invited girls must also be tallied. Moreover, there are 20 guest girls, so 19 of them must welcome the mothers. As a result, there will be 361 pleasantries exchanged between the mothers and the guest daughters.

In total, the number of greetings will be 38 + 760 + 361 = 1159.

The simplest form of the expression is -3x³ + 2x² + 13x -10

An algebraic expression in mathematics is an expression that is made up of letters and numbers, along with algebraic operations (addition, subtraction, multiplication, etc).

-(x − 2)(3x² + 4x − 5) can be expressed in simplest form as follows:

-(x − 2)(3x² + 4x − 5) = (-x +2)(3x² + 4x − 5)

                                 = -x(3x² + 4x − 5) + 2(3x² + 4x − 5)      

                                 = -3x³-4x²+5x + 6x²+8x-10

Answer:

Step-by-step explanation:

a)  How much will you have at the middle of the first year?

Using the formula

\(A\:=\:P\left(1+\frac{r}{n}\right)^{nt}\)

where

Given:

Principle P = $300

Annual rate r = 6% = 0.06 per year

Compound n = Semi-Annually = 2

Time (t in years) = 0.5 years

To determine:

Total amount = A = ?

Using the formula

\(A\:=\:P\left(1+\frac{r}{n}\right)^{nt}\)

substituting the values

\(A=300\left(1+\frac{0.06}{2}\right)^{\left(2\right)\left(0.5\right)}\)

\(A=300\cdot \frac{2.06}{2}\)

\(A=\frac{618}{2}\)

\(A=309\) $

Therefore, the total amount accrued, principal plus interest,  from compound interest on an original principal of  $ 300.00 at a rate of 6% per year  compounded 2 times per year  over 0.5 years is $ 309.00.

Part b) How much at the end of one year?

Using the formula

\(A\:=\:P\left(1+\frac{r}{n}\right)^{nt}\)

where

Given:

Principle P = $300

Annual rate r = 6% = 0.06 per year

Compound n = Semi-Annually = 2

Time (t in years) = 1 years

To determine:

Total amount = A = ?

so using the formula

\(A\:=\:P\left(1+\frac{r}{n}\right)^{nt}\)

so substituting the values

\(A\:=\:300\left(1+\frac{0.06}{2}\right)^{\left(2\right)\left(1\right)}\)

\(A=300\cdot \frac{2.06^2}{2^2}\)

\(A=318.27\) $

Therefore, the total amount accrued, principal plus interest,  from compound interest on an original principal of  $ 300.00 at a rate of 6% per year  compounded 2 times per year  over 1 year is $ 318.27.
