Shaniece took a taxi from her house to the airport. The taxi company charged a pick-up fee of $3.40 plus $3.50 per mile. The total fare was $80.40, not including the tip. Write and solve an equation which can be used to determine x, the number of miles in the taxi ride.

Answer:

B

Step-by-step explanation:

reduction is [tex]\frac{4}{5}[/tex] per plant , that is

[tex]\frac{4}{5}[/tex] × $6 = 0.8 × $6 = $4.80 per plant

total cost = 5 × $4.80 = $24.00

Answer:

x = 5, y = 25

Step-by-step explanation:

I use the substitution method to solve. (I hope I got the equations correct)

6x + y = 55 ---1

10x + 3y = 125 ---2

From 1: y = 55 - 6x ---3

Substitute 3 into 2:

10x + 3(55 - 6x) = 125

10x + 165 - 18x = 125

- 8x = - 40

x = 5

Substitute x into 3

y = 55 - 6(5) = 25

Boat B's relative bearing to Boat A is 27.65

The angle between the travel direction and another direction is known as the relative bearing. From the current direction, this angle is measured in a clockwise motion. As an illustration, a ship is now moving at a bearing of 050°. From the ship's present direction, a relative bearing of 010° is calculated. Bearings can be used to show both the direction and the angle of a certain location. In math, bearings are three-digit angles measured clockwise from a protractor's zero-degree point. On your GCSE math test, the north direction (or starting point) is typically given in the question text.

In order for everyone to have an identical number of sandwiches and corn dogs, with nothing left over, a maximum of 15 people, each person gets 2 corn dogs and 1 sandwich. Note that this is an HCF problem.

The HCF (Highest Common Factor) of two numbers is the highest number among all of the provided numbers' common factors. The HCF of 10 and 30, for example, is 10 since 10 is the highest common factor of 10 and 30.

In this case, the HCF is 15.

Proof:

We can divide 30/15 and still get an integer

= 2

hence we can distribute the sandwiches in 15 ways making 15 people. Hence, each person will get 2 Corn Dogs leaving no remainder.

Answer: {x,y,z}={-11/14,27/7,-41/14}

Step-by-step explanation:

System of Linear Equations entered :

 [1]           x+y-z=6

 [2]           2x-3y+2z=-19

 [3]           -x+4y-x=17

Equations Simplified or Rearranged :

  [1]    x + y - z = 6

  [2]    2x - 3y + 2z = -19

  [3]    -2x + 4y = 17

Solve by Substitution :

// Solve equation [1] for the variable  y

 [1]    y = -x + z + 6

// Plug this in for variable  y  in equation [2]

  [2]    2x - 3•(-x +z +6) + 2z = -19

  [2]    5x - z = -1

// Plug this in for variable  y  in equation [3]

  [3]    -2x + 4•(-x +? +6) = 17

  [3]    -6x = -7

// Solve equation [2] for the variable  z

 [2]    z = 5x + 1

// Plug this in for variable  z  in equation [3]

  [3]    -6x = -7

  [3]    14x = -11

// Solve equation [3] for the variable  x

  [3]    14x = - 11

  [3]    x = - 11/14

// By now we know this much :

   x = -11/14

   y = -x+z+6

   z = 5x+1

// Use the  x  value to solve for  z

   z = 5(-11/14)+1 = -41/14

// Use the  x  and  z  values to solve for  y

 y = -(-11/14)+(-41/14)+6 = 27/7

Solution :

{x,y,z} = {-11/14,27/7,-41/14}

Using the binomial distribution, it is found that the mean for the number of people with the genetic mutation in such groups of 800 is of 72

What is the binomial probability distribution?

It is the probability of exactly x successes on n repeated trials, with p probability of a success on each trial.

The expected value of the binomial distribution is:

E(X) = np

In this problem, we have that:

About 9% of the population has a particular genetic mutation, hence p = 0.09

800 people are randomly selected, hence n = 800.

Then, the mean is given by:

Slopes are mentioned below.

Slope, usually referred to as rise over run, is the "steepness" of the line. By dividing the difference in y values between two points by the difference in x values, we may determine slope. A line's slope often indicates the steepness and direction of the line. By calculating the difference between the coordinates of the two points, (x1,y1) and (x2,y2), it is simple to calculate the slope of a straight line between them. The letter "m" is frequently used to denote slope.

The terms "linear function" in mathematics apply to two different but related ideas: A polynomial function of degree zero or one that contains a straight line as its graph exists directed to as a linear function in calculus and related fields.

The given parameters exists:

Initial = 9000

Rate = 1500

The function exists estimated as: y = Initial + Rate × h

Where h represents the number of hours.

Let the equation be y = Initial + Rate × h

Substituting the values in the above equation, we get

y = 9000 + 1500 × h

y = 9000 + 1500 h

The slope of the graph that passes through points (1, -2) and (0, 2) is: -4.

Using two points on a given graph, (x1, y1) and (x2, y2), the slope (m) of the graph can be calculated by plugging the coordinates of the two points into the slope formula:

Slope (m) = change in y/change in x = (y2 - y1)/(x2 - x1).

Given two points on a line as shown in the graph attached below, (1, -2) and (0, 2), the slope of the graph is calculated as:

Let,

(1, -2) = (x1, y1)

(0, 2) = (x2, y2)

Plug in the values:

Slope of the graph (m) = (2 - (-2))/(0 - 1)

Slope of the graph (m) = (2 + 2)/(0 - 1)

Slope of the graph (m) = 4/-1

Slope of the graph (m) = -4.

Simply put, probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of several outcomes. Statistics is the study of events that follow a probability distribution.

Probability is the ratio of favorable outcomes to all other potential outcomes of an event.

Answer:

(a) Fermat's little theorem states that for any prime p , we have

a^p-1 = 1 (mod p).

for any integer ,a. Then

999999 = 1000000 - 1 = 10^6 - 1 = 1 - 1 = 0 (mod 7)

so 7 does indeed divide 999,999.

(b) Generalizing, we have

10^12n - 1 = 999...999 (12n nines) = (10^n)^12 - 1 = 0 (mod 13)

for positive integer, n. Now, since 1 = 1001 - 1000 and -1 = (mod 1001) , it follows that 10^3 is its own inverse modulo 1001, i.e.

10^3 x = 1 (mod 1001) -----> x = 10^3

This means

10^12n = (10^3 x 10^3)^2n = 1^2n = 1 (mod 1001) ----> 10^12n - 1 = 0 (mod 1001)

Given that,

In the picture we can see there is a line with an intersection line.

A transversal is a line that creates angles when it crosses two parallel lines (or lines on a plane) at various points.

∠3 =(13x+7)° and

∠6 =(9x+59)°

In the parallel lines alternatives angles are always equal.

So,

∠3=∠6

13x+7=9x+59

13x-9x=59-7

4x=52

x=52/4

x=13

Now,

∠3 =(13x+7)°=(13×13+7)°=(169+7)°=176°

∠6 =(9x+59)°=(9×13+59)°=(117+59)°=176°

Now,

From the supplementary angles.

∠5+∠6=180°

In an equation such as the quadratic equation, cubic equation, etc., a polynomial function is a function that only involves non-negative integer powers or only positive integer exponents of a variable. For instance, the polynomial 2x+5 has an exponent of 1.

The multiplicity of a member of a multiset in mathematics is the number of times the member appears in the multiset. The multiplicity of a root, for instance, is how many times a given polynomial has a root at a particular point.

Here the given conditions are:

Fifth degree, 3 is a zero of multiplicity 4,-4 is the only other zero, leading coefficient is 3.

Let y be the f(x) and x be the variable.
