The value of the expression 2⁴/2⁷ = 1/8.

A student is asked to evaluate the expression 2⁴/2⁷.

And the student wrote the answer for this expression as 8.

The student made the mistake of subtracting 7 from 4.

4 - 7 = -3, but the student might have done 7 - 4 = 3 and arrived at the answer as 2³ = 8.

Let us evaluate the given expression.

2⁴/2⁷

Apply exponent rule aⁿ/aˣ = aⁿ⁻ˣ

2⁴/2⁷ = 2⁴ ⁻ ⁷

⇒ 2⁴/2⁷ = 2⁻³ (subtract the numbers: 4 - 7 = -3)

⇒ 2⁴/2⁷ = 1/2³ (apply the exponent rule: a⁻ⁿ = 1/aⁿ)

⇒ 2⁴/2⁷ = 1/8 (2³ = 2 × 2 × 2 = 8)

⇒ 2⁴/2⁷ = 1/8

Answer:

x = 35

Step-by-step explanation:

the sum of the 3 angles in a triangle = 180°

sum the 3 angles and equate to 180

x + 52 + x + 2x - 12 = 180

4x + 40 = 180 ( subtract 40 from both sides )

4x = 140 ( divide both sides by 4 )

x = 35

The total weight of the two animals is 1.3 x 10^4 lbs.

The given parameters are

Animal 1 = 4.23 x 103 lbs.

Animal 2 = 8.7 x 103 lbs.

Rewrite the parameters properly

Animal 1 = 4.23 x 10^3 lbs.

Animal 2 = 8.7 x 10^3 lbs.

The total weight of the two animals is calculated as

Total weight = Animal 1 + Animal 2

This gives

Total weight = 4.23 x 10^3 lbs + 8.7 x 10^3 lbs.

Factor out 10^3 lbs

Total weight = (4.23 + 8.7) x 10^3 lbs.

Evaluate the sum

Total weight = 12.93 x 10^3 lbs.

Rewrite as

Total weight = 1.293 x 10^4 lbs.

Approximate

Total weight = 1.3 x 10^4 lbs.

Hence, the total weight of the two animals is 1.3 x 10^4 lbs.

The standard deviation of the method is 0.7193.

Standard Deviation:

Standard deviation of a data set is the square root of the calculated variance of a set of data.

The formula for standard deviation is,

[tex]\sigma^2 = \dfrac{\Sigma (x_{i} - \mu)^2}{n}[/tex]

Where

xi is an individual value

μ is the mean/expected value

N is the total number of values

Given,

Data set:

20.0, 20.0, 20.0, 20.1, 20.2, 20.5, 20.5, 20.6, 20.7, 20.7, 21.0, 21.2, 21.5, 21.6, 22.1, 22.3

Here we need to find the standard deviation.

To find the standard deviation we have to identify the following from the given set,

They are,

Count, N: 16

Sum, Σx: 333

Mean, μ: 20.8125

Now we have to apply the values on the formula,

In order to solve it,

[tex]\sigma^2=\frac{[(20-20.8125)^2+....+(22.3-20.8125)^2]}{16}[/tex]

When we simplify it then we get,

[tex]\sigma^2=\frac{8.2775}{16}[/tex]

So,

σ = √0.51734375

σ =  0.7193

Therefore, the standard deviation is 0.7193.

Using the mean concept, it is found that you need at least 40 active minutes on Sunday to achieve your goal.

The mean of a data-set is given by the sum of all observations in the data-set divided by the number of observations.

In a week, there will be 7 observations, and a bar graph can represent each observation(time in minutes). They are given as follows:

15, 45, 20, 0, 60, 30 and x.

We want the mean to be of 30, hence:

30 = (15 + 45 + 20 + 0 + 60 + 30 + x)/7

170 + x = 210

x = 210 - 170

The equation for the plane consisting of all points that are equidistant from the points (−7, 1, 1) and (3, 3, 5) is 20x + 4y + 8z = -9.

In order to determine the distance of this plane (x, y, z) with the given points, we would use the distance formula.

Mathematically, the distance between three (2) points that are on a coordinate plane can be calculated by using this formula:

Distance = √[(x₂ - x₁)² + (y₂ - y₁)² + (z₂ - z₁)²]

For these points (x, y, z) and (−7, 1, 1), the distance is given by:

Distance = √[(x₂ - x₁)² + (y₂ - y₁)² + (z₂ - z₁)²]

Distance = √[(x₂ - (-7))² + (y₂ - 1)² + (z₂ - 1)²]

Distance = √[(x₂ + 7)² + (y₂ - 1)² + (z₂ - 1)²]

By using the algebraic formulas, the expanded expression is given by:

(a - b)² = a² - b² - 2ab

(a + b)² = a² + b² + 2ab

Distance = √[(x² + 14x + 49) + (y² - 2y + 1) + (z² - 2z + 1)]   .......equation 1.

For these points (x, y, z) and (3, 3, 5), the distance is given by:

Distance = √[(x₂ - x₁)² + (y₂ - y₁)² + (z₂ - z₁)²]

Distance = √[(x - 3)² + (y - 3)² + (z - 5)²]

Distance = √[(x² - 6x + 9) + (y² - 6y + 9) + (z² - 10z + 25)]    .....equation2.

Since both distances are equidistant, we would equate eqn. 1 and eqn. 2 and then simplify:

√[(x² + 14x + 49) + (y² - 2y + 1) + (z² - 2z + 1)] = √[(x² - 6x + 9) + (y² - 6y + 9) + (z² - 10z + 25)]

(x² + 14x + 49) + (y² - 2y + 1) + (z² - 2z + 1) = (x² - 6x + 9) + (y² - 6y + 9) + (z² - 10z + 25)

x² + 14x + 49 + y² - 2y + 1 + z² - 2z + 1 = x² - 6x + 9 + y² - 6y + 9 + z² - 10z + 25

14x + 6x - 2y + 6y - 2z + 10z + 52 - 43 = 0

20x + 4y + 8z + 9 = 0

An equation is referred to as an identity if it has one or more variables and is true for all alternate values of the variables for which both sides of the equation are defined.

For instance,

the equation x 2 + 2 x = x(x + 2) is an identity since it holds true for all possible replacement values for x.

A conditional equation is one that holds true only for specific replacement values of the variable.

For instance, the equation 3 x + 4 = 25 is a conditional equation because it isn't true for all possible replacement values for x.

Without specifying any limitations, an equation is claimed to be an identity, but in reality, it is only an identity for replacement values for which both sides of the identity are defined.

The steepness of a line is determined by its slope. The slope is m in the equation for a line that is typically used, y = mx + b. The term "rise over run" is also frequently used to describe it and describes how much the y-value changes as the x-value does.

According to the given value;

slope of line is Y₂-Y₁/X₂-X₁

hence slope for given line will be

3-(-2)/5-5 =5/0 = ∞

slope is infinity means straight line is vertical in nature and vertical lines are of the form x=a where a is some constant
