Answer: B

Step-by-step explanation:

The width = 23/4

The length = 2 × the width = 2 × 23/4 = 23/2                

The perimeter of the rectangle = 2 ( length + width)

                                                    = 2 (23/2 + 23/4 )

                                                    = 2 ( 69/4)

                                                    = 69/2

                                                    = 34 .1/2

Answer:

Step-by-step explanation:

We already know how to represent whole numbers on the number line. Let us consider the image shown, here, the digits 0 and 1 are represented on the number line.

Representation of 0 and 1 on The Number Line

If we divide the number line into two equal parts, as shown in the figure below, what value does that mid-point hold? Half of what the graduation between 0 and 1 holds.

So, the point represents (1-0)/2 = ½

Fraction - Representation Of Fraction On The Number Line

Thus we saw, to represent a fraction on the number line, we need to divide the line segment between two whole numbers into n equal parts where n represents the denominator of the fraction. For example, if we have to represent the fraction 1/5 on the number line, hence, we need to divide the line segment between 0 and 1 into five equal parts, where the first point as shown in the figure represents the fraction 1/5, the second represents 2/5 and so on.

Fraction Representation

We must note that, 0/5 = 0 here and 5/5 = 1.

Here you have seen the representation of proper fraction on the number line. To represent improper fractions, you first convert them into mixed fractions. The same procedure, as shown above, is used with the whole number as the starting point.

Because it is more robust, or unaffected by the specific numerical values of those outliers, the median is typically a better indicator of the center when there are extreme values or outliers.

What is mean, median and mode?

The sum of the numbers is added, and the result is divided by the total number of numbers in the list to determine the arithmetic mean. An average usually refers to anything like this. In a list with values ranging from smallest to largest, the median is the middle value. On the list, the mode appears the most frequently.

As given, a high school basketball player is creating a scout summary of their sophomore season.

The points are,  29, 24, 32, 20, 0, 22, 28, 29 33, 34, 30, and 27.

Arrange these numbers in ascending order,

0, 20, 22, 24, 27, 28, 29, 29, 30, 32, 33, 34.

So,

Mean = (0 + 20 + 22 + 24 + 27 + 28 + 29 + 29 + 30 + 32 + 33 + 34) / 12

Mean = 308 / 12

Mean = 28

Median = 29

Mode = 29 (2 times repeating)

Because it is more robust, or unaffected by the specific numerical values of those outliers, the median is typically a better indicator of the center when there are extreme values or outliers.

The equation of a line which is parallel to the given line; y = 6x - 2 as required in the task content is; Choice D-y = 6x + 3.

It follows from the task content that the equation of a line which is parallel to the given equation; y = 6x - 2 is to be determined.

First, by comparison the given equation with the slope-intercept model of a linear equation; y = mx + c. where m is slope and c is y-intercept.

Slope, m = 6.

Hence, since parallel lines are lines which have equal slopes.

The slope of the required line is therefore; 6 and it's y-intercept (0, 3) has a y-coordinate of; 3.

The required equation of the line is therefore; y = 6x + 3.

The error in balancing the equation is that the although the number terms on both sides of the equation are the same, the operation on the 1 on the left is an addition while the operation on the number 1 on the Right Hand Side of the equation is a subtraction

A balanced equation is one in which the values or amounts on both sides of the equation are the same.

The unbalanced equation is presented as follows;

16 ÷ 8 = 16 ÷ 8 - 1

The form balanced equation in the question is; 16 ÷ 8 + 1 = 16 ÷ 8 - 1

The error is that in the balanced equation a 1 was added to the Left Side of the equation, while in the unbalanced equation, the difference between the left and right side of the equation is a subtraction of a 1 from the Right Hand Side of the equation.

The step to correctly balance the unbalanced equation involves the subtraction of a 1 from the Left Hand Side as follows;

The unbalanced equation 16 ÷ 8 = 16 ÷ 8 - 1 can be balanced by applying the addition (or subtraction) property of equality, which states that the when the same quantity is added (or subtracted) from two quantities that are initially equal, the resulting quantities that have a different amount following the addition (or subtraction) will remain equal.

The expression, 16 ÷ 8 and 16 ÷ 8 are the same.

Subtracting the same amount of 1 from both sides will result in two new expressions that are also equal in amount as follows;

16 ÷ 8 = 16 ÷ 8

16 ÷ 8 - 1 = 16 ÷ 8 - 1

The error is therefore in adding rather than subtracting a 1 from the Left Hand Side of the equation to balance the equations.

Using ratios and proportions, the time it takes for both of them to wash both cars is 24 minutes

Proportion is explained majorly based on ratio and fractions. A fraction, represented in the form of a/b, while ratio a:b, then a proportion states that two ratios are equal. The ratio is a way of comparing two quantities of the same kind by using division. The ratio formula for two numbers a and b is given by a:b or a/b. Multiply and dividing each term of a ratio by the same number (non-zero), doesn’t affect the ratio.

When two or more such ratios are equal, they are said to be in proportion.

In this congruent of the triangle its proven that AB = CD.

What is congruent of the triangle?

The shapes maintain their equality regardless of how they are turned, flipped, or rotated before being cut out and stacked. We'll see that they'll be placed entirely on top of one another and will superimpose one another. Due to their identical radius and ability to be positioned directly on top of one another, the following circles are considered to be congruent.

Any two figures can be perfectly positioned over one another to demonstrate their congruence. The relationship between two figures that are said to be congruent is described using the word "congruence."

Left Hand Derivative [tex]\lim_{x \to 1^-} f'(x)[/tex] = -6 and

So, the function f(x) is neither continuous nor differentiable at x = 1.

f(x) =

Now, for  [tex]\lim_{x \to 1^-} f(x)[/tex] we will consider the function  3㏑(3 - 2x) + 3, as we have to find the Left Hand Limit of the function, at x = 1.

[tex]\lim_{x \to 1}[/tex] 3㏑(3 - 2x) + 3 = 3㏑(3 - 2(1)) + 3

Now, for [tex]\lim_{x \to 1^+} f(x)[/tex] we will consider the function -3x² + 4, as we have to find the Right Hand Limit of the function, at x = 1.

[tex]\lim_{x \to 1}[/tex] -3x² + 4 = -3(1)² + 4

Now, for [tex]f(1)[/tex] we will consider the function -3x² + 4,

[tex]f(1)[/tex] = -3(1)² + 4

= -3 + 4

Now, for [tex]\lim_{x \to 1^-} f'(x)[/tex] we will consider the derivative of the function

3㏑(3 - 2x) + 3,

[tex]\lim_{x \to 1}[/tex] -6/(3 - 2x) = -6/(3 - 2(1))

Given is the quadratic equation.

A quadratic equation has two real solutions if the discriminant is positive.

The rate of change of the parabola on the interval [0, 4] is 0.

For any function f(x), we define the rate of change on an interval [a, b] as:

R = (f(b) - f(a))/(b - a)

Here we want to get the rate of change on the interval [0, 4], and we know that the graph has the points:

(0, 4), (2, -4), (4, 4)

Then:

f(0) = 4

f(4) = 4

Replacing that in the rate of change formula we get:

R = ( f(4) - f(0))/(4 - 0)

R = (4 - 4)/4 = 0

The rate of change on that interval is 0.

The compound interest after 7 years is $2701.

What is compound interest?

The interest on savings that is computed on both the initial principal and the interest accrued over time is known as compound interest. Compound interest is computed by multiplying the starting principal amount by one and the annual interest rate raised to the number of compound periods minus one. The final step is to deduct the initial loan principal from the calculated value.

When the amount compounds quarterly, it means that the amount compounds 4 times in a year. i.e., n = 4. We use this fact to derive the quarterly compound interest formula. Thus, the quarterly compound interest formula is:

A = P (1 + r/12)[tex].^{n/12}[/tex]

A = 2100(1+3.6/12)[tex].^{7/12}[/tex]

A=2701

Since a lottery ticket is discarded after winning a prize,
