Carson rides his bike for 30 min each day. He rides a total of 12 mi every 3 days. Based on this information, how many days will it take Carson to ride a total of 80 mi on his bike?

Answer:

Step-by-step explanation:

interval in mathematics stands for a set of real numbers,

denoted by [a,b] where a and b are the starting and ending real numbers both inclusive respectively.

thus, interval [a,b] is the set of real numbers starting from a to b both are real numbers and are included.

The probability is 1, or 100%, that a randomly selected person from this sample believed either the true headline or the false headline.

Probability is a measure of the likelihood or chance that a specific event will occur. It is expressed as a number between 0 and 1, where 0 indicates that an event is impossible and 1 indicates that an event is certain to occur.

The probability that a randomly selected person from this sample believed the true headline or believed the false headline can be calculated by adding the number of people who believed the true headline to the number of people who believed the false headline and dividing by the total sample size.

In this case, the number of people who believed the true headline is 120, and the number of people who believed the false headline is 80. Therefore, the total number of people who believed either headline is 120 + 80 = 200.

The total sample size is also 200, so the probability that a randomly selected person from this sample believed the true headline or believed the false headline is:

(120 + 80) / 200 = 200 / 200 = 1

Therefore, the probability is 1, or 100%, that a randomly selected person from this sample believed either the true headline or the false headline.

Step-by-step explanation:

Given the points R(-4, 5) and S(2, -1), to get the distance between the points, we will use the formula;

D = √(x2-x1)²+(y2-y1)²

Given x1= -4, y1 = 5, x2 = 2 and y2 = -1

RS = √(2-(-4))²+(-1-5)²

RS = √(6)²+(-6)²

RS = √36+36

RS = √72

RS = √2×36

RS = 6√2units

To get the midpoint, we will use the formula M(X,Y) = (x1+x2/2, y1+y2/2)

(X,Y) = (-4+2/2, -1+5/2)

(X,Y) = (-2/2, 4/2)

(X,Y) = (-1,2)

Hence the midpoint is (-1,2)

To get a point P 1/3 of the distance of RS, we will multiply 1/3 with the the distance RS as shown

P = 1/3 × 6√2

P = 2√2

The number of hours a student should spend on their homework to expect a score of 85 on the quiz.

Step-by-step explanation:

When y = 85, that means Emily scores 85 and she spent 4.54 hours on homework.

An equation is said to be linear equation in two variables if it is written in the form of ax + by + c=0, where a, b & c are real numbers and the coefficients of x and y, i.e. a and b respectively, are not equal to zero.

The substitution method is the algebraic method to solve simultaneous linear equations.

According to the given question.

We have

A linear equation in two variable,

\(y = 6.6x + 55...(i)\)

In which x represents hours spent on homework.

And, y represents the expected quiz score.

Substitute, y = 85 in equation (i).

⇒ \(85 = 6.6(x) = 55\)

⇒\(85 - 55 = 6.6x\)

⇒ \(30 = 6.6x\)

⇒ \(x = 4.54\)

Hence,  when y = 85 means Emily scores 85 and she spent 4.54 hours on homework.

The volume of the solid is 4/5π.

The volume of a solid generated by revolving a region around a line is given by V = ∫a b π(y)2dy, where a and b are the lower and upper limits of the region, respectively, and y is a function of x.

In this case, the region is bounded by the graph of y=x3, the y-axis, and the horizontal line y=1. Therefore, the volume of the solid generated when the region is revolved about the y-axis is given by

V = ∫0 1 π(y)2dy

= ∫0 1 πx6dx

= π/7

= 4/5π

The volume of the solid is calculated using the formula V = ∫a b π(y)2dy, where a and b are the lower and upper limits of the region and y is a function of x. In this case, the lower limit is a=0 and the upper limit is b=1, since the region is bounded by the graph of y=x3, the y-axis, and the horizontal line y=1. Integrating from a=0 to b=1 gives the volume of the solid as V = ∫0 1 πx6dx = π/7 = 4/5π.

As the angle increases from 0 to π/2, the value of sine increases, and the value of cosine decreases.

Trigonometry is a branch of mathematics that deals with the relationships between angles and sides of triangles.

Let us first understand the concept of sine and cosine. In a right-angled triangle, the sine of an angle is defined as the ratio of the length of the side opposite to the angle and the length of the hypotenuse. Similarly, the cosine of an angle is defined as the ratio of the length of the adjacent side and the length of the hypotenuse.

As the angle θ increases from 0 to π/2, the length of the opposite side (the numerator in sine) of the triangle increases, and the length of the hypotenuse (the denominator in sine) remains the same. Therefore, the value of sine increases as θ increases.

On the other hand, as the angle θ increases from 0 to π/2, the length of the adjacent side (the numerator in cosine) decreases and the length of the hypotenuse (the denominator in cosine) remains the same. Therefore, the value of cosine decreases as θ increases.

This behavior is consistent with the fact that sine is an increasing function, while cosine is a decreasing function within this range of angles.

From the question, we have the following parameters that can be used in our computation:

The circle

The theorem of intersecting chords can also be used to find the measure of an arc in a circle.

Specifically, if two chords intersect inside a circle, then the sum of the measures of the arcs intercepted by one chord is equal to half the sum of the measures of the arcs intercepted by the other chord and vice versa

Using the theorem of intersecting chords. we have

x = 1/2 * (77 + 55)

Answer:

\((x - 9)(x - 1)\)

Step-by-step explanation:

We can factor the trinomial using the rule:

IF \(x^2 + cx + d = (x + a)(x + b)\),

THEN \(a + b = c\) and \(a \cdot b = d\).

We know that -9 and -1 add to -10. They also multiply to 9.

Therefore, we can factor \(x^2 - 10x + 9\) as:

\(\boxed{(x - 9)(x - 1)}\)

The factors of the given trinomial are (x-9)(x-1).

Trinomial is a polynomial having 3 terms. At least one variable and one operation (addition, subtraction, multiplication, division) must be present in an algebraic expression.

Given that, a trinomial x² - 10x + 9, we need to find the factors,

So,

x² - 10x + 9

= x² - 9x - x + 9

= x(x-9) -1(x-9)

= (x-9)(x-1)

Hence, the factors of the given trinomial are (x-9)(x-1).

These standardization methods are crucial in chromatography to ensure accurate quantification and comparability of results.

In chromatography, standardization methods are used to ensure accurate and reliable results by establishing reference points or calibration standards. Here are three common methods of standardization in chromatography: External Standardization: In this method, a set of known standard samples with known concentrations or properties is prepared separately from the sample being analyzed. These standards are then analyzed using the same chromatographic conditions as the sample. By comparing the response of the sample to that of the standards, the concentration or properties of the sample can be determined. Internal Standardization: This method involves the addition of a known compound (internal standard) to both the standard solutions and the sample. The internal standard should ideally have similar properties to the analyte of interest but be different enough to be easily distinguished. The response of the internal standard is used as a reference to correct for variations in sample preparation, injection volume, and instrumental response. Internal standardization helps improve the accuracy and precision of the analysis. Standard Addition: This method is useful when the matrix of the sample interferes with the analysis or when the analyte concentration is unknown. It involves adding known amounts of the analyte of interest to different aliquots of the sample. The response of the analyte is then measured, and the concentration is determined by comparing the response with that of the standards. The difference in response between the sample and the standards allows for the determination of the analyte concentration in the original sample.

The sequence of step functions converges to a function that is not continuous on \([a, b]\), demonstrating an example where pointwise convergence does not imply continuity.

One example of a sequence of functions on \([a, b]\) that converges to a function that is not continuous on \([a, b]\) is the sequence of step functions.

Let's consider a specific example:

Let \(f_n(x)\) be a sequence of step functions defined on \([0, 1]\), where each \(f_n(x)\) is constant on subintervals of equal length. As \(n\) approaches infinity, the width of each subinterval approaches zero, and the height of each constant segment approaches infinity.
