Answer:

They rode 14 miles before replacing each horse

Step-by-step explanation:

We will be working under the assumption that all three riders sat on one horse at a time and rode it while the other horses rested.

From the problem, we can understand that the horses were each ridden for the same distance. This means that to get the total distance a horse rode before it was changed, we can divide the total distance by the number of horses that were used for the journey.

Distance each horse rode = 182/ 13 = 14 miles.

Therefore, each horse was ridden for 14 miles before it was changed.

Answer:

these are tough,   it takes a lot of practice to get used to these, sooo

Step-by-step explanation:

we know the slope, m= -5/3,   and we're given a point so use the point slope formula

y= mx + b

the point we are given is in this form  (x,y)

then plug the information into our point slope formula

y = (-5/3) x  + (-2)

y = -5x/3 -2

\( \:\:\:\:\:\:\longrightarrow \sf \underline{Mean = \dfrac{Sum\: of \: Observations }{No.\:of \:Observations }}\\\)

As per question, we are given -

\( \:\:\:\:\:\:\longrightarrow \sf 9+4+8+8+7+x \\\)

\( \:\:\:\:\:\:\longrightarrow \sf 36+x \\\)

Now that, we are given all the values which are required for solving this problem, so we can substitute the values and solve for the sixth datum -

\( \:\:\:\:\:\:\longrightarrow \sf Mean = \dfrac{Sum\: of \: Observation }{No.\:of \:Observation }\\\)

\( \:\:\:\:\:\:\longrightarrow \sf 7 = \dfrac{36+x}{6}\\\)

\( \:\:\:\:\:\:\longrightarrow \sf 7\times 6 = 36+x \\\)

\( \:\:\:\:\:\:\longrightarrow \sf 42 -36 =x\\\)

\( \:\:\:\:\:\:\longrightarrow \sf \underline{x = 6}\\\)

The average rate of change of the function from x = 0 to x = 2 is -2

From the complete question (see attachment), we have the following ordered pair when x = 0 and x = 2

\((x,y) = \{(0,10)\ (2,6)\}\)

The average rate of change is calculated using:

\(\Delta x = \frac{y_2 -y_1}{x_2 -x_1}\)

So, we have:

\(\Delta x = \frac{6-10}{2-0}\)

Evaluate common terms

\(\Delta x = \frac{-4}{2}\)

Divide -4 by 2

\(\Delta x = -2\)

Hence, the average rate of change of the function from x = 0 to x = 2 is -2

The statement regarding the diagram "m∠KML + m∠MLK = m∠JKM" is true option (B) m∠KML + m∠MLK = m∠JKM is correct.

In terms of geometry, the triangle is a three-sided polygon with three edges and three vertices. The triangle's interior angles add up to 180°.

We have a triangle shown in the picture:

As we know, triangle is a polygon with three sides and three interior angles.

From the definition of the triangle, The triangle's interior angles add up to 180°

m∠MKL + m∠MLK + m∠KML = 180

Also, the sum of the two interior angles is equal to the exterior angle.

m∠KML + m∠MLK = m∠JKM

Answer:

Step-by-step explanation:

Log(1), log(-1), log(i) and ii are all numbers written in the form a + bi. Log(1) = 0; log(-1) = undefined; log(i) = 0.5i; ii = -1; a = -1 and b = 0 because the number is in the form a + bi.

Given numbers are;• log(1)• log(-1)• log(i)• iiFor all numbers written in the form a + bi, we must find a and b. Here's how to do it: log(1)In this case, the log is taken in base 10. The result of this is 0. So, we have: log(1) = 0Therefore, a=0 and b=0 because the number is not in the form a + bi. log(-1)In this case, the log is taken in base 10. The result of this is undefined. This is because there is no power to which we can raise 10 to get -1. So, we have: log(-1) = undefinedTherefore, a=undefined and b=undefined because the number is not in the form a + bi. log(i)In this case, the log is taken in base 10. The result of this is 0.5iπ. So, we have: log(i) = 0.5iπTherefore, a=0 and b=0.5π because the number is in the form a + bi. iiIn this case, we are finding the square of i. i is a complex number given as i = 0 + 1i. Therefore, we have: i2 = (0 + 1i)2= (0)2 + 2(0)(1i) + (1i)2= -1This is because i2 = -1. Now, we can write ii as: ii = i × i= (0 + 1i) × (0 + 1i)= 0 + 0i + 0i + 1i2= -1So, we have: ii = -1Therefore, a=-1 and b=0 because the number is in the form a + bi.

The probability of choose one mine over the other is  0.5/0.95 and 0.45/0.95

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics. The range of the value is 0 to 1. Probability has been incorporated into mathematics to predict the likelihood of different events.

The ratio of positive outcomes to all possible outcomes is used as the formula to determine an event's probability. Probabilities are always in the 0 to 1 range. The generic probability equation can be written as follows: Number of Favorable Outcomes / Total Number of Outcomes is the formula for probability.

Given ,

1 mine =0.5

another mine = 0.45

so the probability of choose one mine over the other will be

0.5+045 = 0.95 is the total

0.5/0.95 and 0.45/0.95

Therefore the probability of choose one mine over the other is  0.5/0.95 and 0.45/0.95

The probability of choose one mine over the other is  0.5/0.95 and 0.45/0.95.

Given ,

1 mine =0.5

another mine = 0.45

so the probability of choose one mine over the other will be

0.5+045 = 0.95 is the total

\(\begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{8}=\stackrel{m}{ 8}(x-\stackrel{x_1}{1}) \\\\\\ y-8=8x-8\implies {\Large \begin{array}{llll} y=8x \end{array}}\)

Answer:

\(y=8x\)

Step-by-step explanation:

We can see that this line has a constant of proportionality. That is — x is proportional to y and vice versa. This means that the equation for the line's equation will be in the form:

\(y = mx\)

where \(m\) is the ratio of x to y.

This ratio is also known as the line's slope. We can solve for the slope using the equation:

slope = rise / run

slope = \(\Delta\)y / \(\Delta\)x

slope = 8 / 1

slope = 8

\(m=8\)

So, the equation of the line is:

\(y=mx\)

\(\boxed{y=8x}\)

It is a function because every Celsius temperature is associated with only one Fahrenheit temperature. Therefore, option B is true.

We are given that the temperature in degrees Celsius C can be converted to degrees Fahrenheit F

We know that the formula

\(\dfrac{C}{5} = \dfrac{F - 32}{9}\)

If we are substituting c = -40

Then, we get

\(\dfrac{C}{5} = \dfrac{F - 32}{9}\\\\\dfrac{-40}{5} = \dfrac{F - 32}{9}\\\\-8 \times 9 = F - 32\\\\F = -72 + 32\\\\F = -40\)

For every Celsius temperature, we get only one value of Fahrenheit.

The function is one-one because for every value of Celsius we get a unique value of Fahrenheit.

Hence, it is a function because every Celsius temperature is associated with only one Fahrenheit temperature.

Therefore, option B is true.

(a) No, the operation * is not closed on the real numbers.

To determine closure, we need to check if for any two real numbers x and y, xy is also a real number. However, if we choose r to be any real number other than 1, the result of xy will involve a term (-ry) that may not be a real number, breaking closure.

(b) No, the operation * is not commutative.

Commutativity requires that xy = yx for all real numbers x and y. However, in this case, xy = x + y - ry, while yx = y + x - rx. Since ry and rx are not generally equal, the operation is not commutative.

(c) No, the operation * is not associative.

Associativity requires that (xy)z = x(yz) for all real numbers x, y, and z. However, if we substitute the definition of * into both sides of the equation, we get different expressions that are generally not equal. Therefore, the operation * is not associative.

(d) Yes, the operation * has an identity element.

The identity element e is a real number such that for any real number x, xe = ex = x. In this case, choosing e = 0 satisfies the identity condition, as x0 = x + 0 - r0 = x. However, not every real number has an inverse since there are values of x for which xy = e has no solution, violating the requirement for every element to have an inverse.

(e) No, (R, *) is not a group.

A group requires closure, associativity, an identity element, and every element having an inverse. Since the operation * fails to satisfy closure and does not have inverses for all real numbers, it cannot form a group.
