The expression  \(^3\sqrt {27x} + ^3\sqrt{x}\) is equivalent to 0 when x=0.

What is the equivalent expression?

Equivalent expressions are expressions that perform the same function despite their appearance. If two algebraic expressions are equivalent, they have the same value when we use the same variable value.

If x=0, then the expression \(^3\sqrt {27x} + ^3\sqrt{x}\) becomes:

And we are given that x=0. So, we can substitute x=0 into the expression:

\(^3\sqrt{ 27 * 0} + ^3\sqrt{0}\)

= 0 + 0 = 0

The first term simplifies to ∛(0), which is 0, because any number raised to the 1/3 power and multiplied by 0 is equal to 0.

The second term also simplifies to ∛(0), which is 0, because any number raised to the 1/3 power and multiplied by 0 is equal to 0.

Therefore, the sum of the two terms is 0.

Hence, the expression  \(^3\sqrt {27x} + ^3\sqrt{x}\) is equivalent to 0 when x=0.

Histograms are used to represent the distribution of continuous or interval data, while bar charts are used to compare different categories or groups of categorical or discrete data.

The difference between a histogram and a bar chart lies in the type of data they represent and the way they are used. Data Representation: Histogram: A histogram is used to display the distribution of continuous or interval data. It represents the frequency or count of data within specific intervals or bins. The x-axis of a histogram represents the range of values or intervals, while the y-axis represents the frequency or count of data points within each interval.

Bar Chart: A bar chart is used to compare different categories or groups of categorical or discrete data. It represents the magnitude or value of each category as separate bars. The x-axis of a bar chart represents the categories, and the y-axis represents the magnitude or value being measured. Data Type: Histogram: Histograms are suitable for displaying continuous or interval data, such as measurements on a scale (e.g., height, weight, time). The data points are grouped into intervals or bins, and the frequency or count of data within each bin is represented.

Bar Chart: Bar charts are suitable for representing categorical or discrete data, where the data points belong to distinct categories or groups. Each category is represented by a separate bar, and the height or length of the bar indicates the magnitude or value associated with that category.

Usage: Histogram: Histograms are commonly used in statistics and data analysis to visualize the distribution of data and identify patterns, central tendencies, and outliers within a continuous dataset.

Bar Chart: Bar charts are widely used in various fields to compare and present categorical data, such as comparing sales figures by product categories, analyzing survey responses by different groups, or displaying the frequency of different outcomes in a dataset.

Time taken by Adam to complete his seventh lap of the circular track as per given data is equal to 1minute 28seconds.

As given in the question,

Time taken by Adam to complete hi first lap of circular track = 1 min 58 sec

First term t₁ = 1 minute 58seconds

Time taken by each successive lap is 5seconds less then the previous lap

Common difference 'd' = -5seconds

let time taken to complete the seventh lap be t₇

t₇ = t₁ + ( 7 - 1 ) d

⇒ t₇ = 1 minute 58 seconds + ( 6 ) (- 5seconds)

       =  1 minute 58 seconds - 30seconds

      = 1 minute 28 seconds

The roof lets in 663 watts of light per square meter.

If 780 watts per square meter (w/m2) of light strikes the roof and it has an 85% transmittance, 85% of the light goes through the roof, and the other 15% is absorbed or reflected by the roof.

We can apply the following calculation to determine how many watts per square meter of light travel through the roof:

(Percent transmittance / 100) x Watts of light striking the roof = Watts of light going through the roof

When we substitute the provided values, we get:

Light streaming through the roof in watts = (85 / 100) x 780 w/m2

Light flowing through the roof in watts = 0.85 x 780 w/m2.

Light coming through the roof in watts = 663 w/m2 (rounded to the next whole number)

As a result, The roof lets in 663 watts of light per square meter.

Answer: Let's use "x" to represent the number of electoral votes in Florida. Then, we can write the equation for North Carolina's number of electoral votes as "x - 12".

The equation can then be written as:

x + (x - 12) = total number of electoral votes

Solving for x, we get:

2x - 12 = total number of electoral votes

2x =total number of electoral votes + 12

2x = total number of electoral votes + 12

x = (total number of electoral votes + 12)/2

So, the number of electoral votes for Florida is (total number of electoral votes + 12)/2.

Note: The total number of electoral votes for both states needs to be known in order to solve for the number of electoral votes in Florida.

Poppy's sister used approximately 3.14 inches more wire per wall hanging than Poppy.

To find the amount of wire used by both Poppy and her sister, we'll calculate the circumference of their respective wall hangings using the formula:

C = 2πr

Since the diameter is twice the radius, we can find her sister's radius as follows:

Poppy's radius = 6.25 inches

Poppy's diameter = 2 * 6.25 = 12.5 inches

Sister's diameter = Poppy's diameter + 1 = 12.5 + 1 = 13.5 inches

Sister's radius = 13.5 / 2 = 6.75 inches

Now, we'll calculate the circumferences using the given value for π:

Poppy's circumference = 2 x 3.14 x 6.25 ≈ 39.25 inches

Sister's circumference = 2 x 3.14 x 6.75 ≈ 42.39 inches

Difference = Sister's circumference - Poppy's circumference

Difference = 42.39 - 39.25 = 3.14 inches

The dimensions of the rectangular pool are (2x − 1) and (3x − 3). The length of the pool is 3x − 3 and the width of the pool is 2x − 1.

The area of Rectangle is length times of width.

Area of rectangular pool = 6x² − 11x + 3

To factor the trinomial, we need to find two binomials that multiply together to give the trinomial 6x² − 11x + 3.

We use product-sum method of factoring to find the two binomials.

We need to find two numbers that multiply to 6 (the coefficient of the x² term) and add to -11 (the coefficient of the x term).

6x² − 11x + 3

6x² −2x-9x + 3

(2x − 1)(3x − 3)

Hence, the dimensions of the rectangular pool are (2x − 1) and (3x − 3). The length of the pool is 3x − 3 and the width of the pool is 2x − 1.

One way analysis of variance (anova) is the option she should use.

It sounds like Barbara wants to compare the self-efficacy of four different groups (plumbers, electricians, lawyers, and college professors). In this case, she should use a one-way analysis of variance (ANOVA) to compare the mean self-efficacy of these groups.

ANOVA is a statistical test that allows you to compare the means of two or more groups. It is used to determine whether there is a significant difference between the means of the groups.

On the other hand, a chi-square test is used to compare the observed frequencies of a categorical variable to the expected frequencies. It is not appropriate for comparing means.

An independent samples t-test is used to compare the means of two independent groups. Since Barbara wants to compare the means of four groups, an independent samples t-test is not appropriate.

A paired samples t-test is used to compare the means of two related groups. It is used when each individual in one group is matched with an individual in the other group. In this case, it does not seem like the groups are related, so a paired samples t-test is not appropriate.

Therefore, the correct answer is: one-way ANOVA.

If a=4, b= 7, and B= 75°, the area of triangle ABC is approximately 13.476 square units.

To find the area of triangle ABC given the values of a, b, and B, we can use the formula:

Area = (1/2) * a * b * sin(B)

where a and b are the lengths of two sides of the triangle and B is the angle between them, measured in degrees.

Substituting the given values, we get:

Area = (1/2) * 4 * 7 * sin(75°)

Using a calculator to evaluate the sine of 75°, we get:

Area = (1/2) * 4 * 7 * 0.96593

Area ≈ 13.476 square units
