What is Co-ordinate Geometry?

Graphs and coordinates are utilised in coordinate geometry to discover information about various geometric figures. A description of the coordinate plane must be included in a definition of coordinate geometry. A coordinate plane, also known as a coordinate graph, is a grid system formed by the intersection of two number lines known as axes. The x-axis is the horizontal number line, and the y-axis is the vertical number line. These axes meet at a position known as the origin.

Solution:

let, the total weight of banana sold be x pounds

and total weight of raspberries soldd be y pounds.

From the data given in the question, the equation formed is

3x + 2.25y = 72

(See Graph)

at x = 28 we will get the value of y as -5.34

which is not a possible solution

The solutions to the given equation are -5/2 and  -3. These answer can get after using quadratic formula.

The quadratic formula is a formula that offers a quadratic equation's solution. In addition to the quadratic formula, other methods of solving quadratic equations include factoring, completing the square, graphing, and others.

In the literature, there are numerous ways to derive the quadratic formula. The common one uses the completing the square method in a straightforward manner.

The given equation is :

-11x = 2x² +15

Move terms to the left side

-11x -(2x^2 +15) =0

Rearrange terms

-2x^2 - 11x -15 = 0

Common factor

-(2x^2+ 11x +15) =0

Divide both sides by the same factor

2x^2 +11x +15 =0

Use the quadratic formula

x = -11 ± √11² - 4 * 2*15/2*2

x =-11±1/4

Solve

x = -5/2

x= -3

The value of x will be -5/2 or -3.

The solution of the system of equations are x = 4 and y = 4.

The system of equations would be solved using the elimination method.

−10x+2y=−32 equation 1

-2x-2y=−16 equation 2

In order to determine the value of x, take the following steps:

Add equation 2 and equation 1 together

-12x = - 48

Divide both sides of the equation by -12

x = -48 / - 12

x = 4

In order to determine the value of y, substitute for x in equation 1:

-(10 x 4) + 2y = -32

-40 + 2y = -32

Combine similar terms:

2y = -32 + 40

Add similar terms:

2y = 8

Divide both sides of the equation by 2

y = 8 / 2

y = 4

The number of way in which bride can rank the three Djs out of 6 is 120.

There are several different ways we might rank the three DJs.

Therefore, we must identify the permutation P. (6,3).

ⁿPₓ = n!/(n - x)!

⁶P₃ = 6!(6-3)!

⁶P₃ = 6×5×4

⁶P₃ = 120

Thus, the number of way in which bride can select the three Djs out of 6 is 120.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Based on the equation given, the equation to represent Amir's information will be:

y = 35 × x

y = 35x

Jesse's equation will be:

y = 30(x + 1)

Then, we'll equate both equations together. This will be:

35x = 30(x + 1)

35x = 30x + 30

35x - 30x = 30

5x = 30

x = 30/5

x = 6

Therefore, the number of pages read will be:

y = 35x

y = 35 × 6

y = 210 pages.

As sample size grows, sample variance (variation among observations) grows, while sample mean variance (standard error) decreases, and therefore precision grows.

The normal curve approximates the sample distribution of averages as well as proportions from just a large number of distinct experiments.

Answer:

Step-by-step explanation:

The different ways that are there for the students to be ordered in the list so that Ed is higher on the list than Ned is 19,958,400

In the order, if Ned comes first on the list then Ed will not be on the list before Ned. (remember for Ed to be higher than Ned on the list, it should come after Ned on the list).

So if Ned is first on the list, then all the remaining (including Ed) can occur anywhere in the remaining list. Hence the total permutations will be 10!

Ned's corresponding choices: 1 109 8 7 6 5 4 3 -2 1

If Ned comes in the second position, then Ed can't come in the first position. Hence in the first position, there are only 9 choices.

*(excluding Ed) Ned * corresponding choices:

= 9*9!

*(including Ed (including Ed) Ned corresponding choices: *k

= 9*8*8!

Total combinations will be:

10! + 9*9! + 9*8*8! + 9*8*7*7! + 9*8*7*6*6! + 9*8*7*6*5*5! + 9*8*7*6*5*4*4! + 9*8*7*6*5*4*3*3! +9*8*7*6*5*4*3*2*2! + 9*8*7*6*5*4*3*2*1*1! .

= 19,958,400

We can directly compute it. Since there will be a total of 11! combinations in which 11!/2 times Ed comes after Ned and 11!/2 times Ed comes before Ned.

and 11!/2 = 39,916,800/2 = 19,958,400

From the concept of similarity

aₙ=a+(n-1)d is the formula can be used to find the nth term of the sequence.

Sequence is an enumerated collection of objects in which repetitions are allowed and order matters.

Given sequence is 5,9,13,17,21

Five comma nine comma thirteen comma seventeen comma twenty one.

We need to find the nth term of the sequence.

Firstly we need to find the sequence is AP or GP.

An arithmetic sequence is a sequence of numbers where the differences between every two consecutive terms is the same.

so 9-5=4,

13-9=4

Hence the sequence is a Aritmetic sequence.

In arithmetic sequence the nth term can be find by using the formula

aₙ=a+(n-1)d

where a is first term and d is common difference.

Hence aₙ=a+(n-1)d is the formula can be used to find the nth term of the sequence.

For the given normal distribution, 95% of the values lie between 40 and 60.

Let the said distribution be X

Here it is given that X follows a normal distribution and it has a mean of 50 and a standard deviation of 5.

Therefore we can write X~ N(50, 25)

Now we need to find P(40< X< 60)

= P(40< X< 60) = P(X < 60) - P(X<40)

To find this we need to convert it into the form of a standard normal and then look up the p-values from the Z-table.

To do this we need to use the formula

P(X < x) = Φ[(x - μ) / σ]

where,

μ is the mean

σ is the standard deviation

Therefore we get

P(X < 60) - P(X<40) = Φ[(60 - 50) / 5] - Φ[(40 - 50) / 5]

= Φ[2] - Φ[-2]

Φ(-x) = 1 - Φ(x)

Therefore,

Φ[2] - Φ[-2]

= 2Φ(2) - 1

We get the p-value

2 X .97725 - 1

= 1.9545 - 1

= 0.9545

= 95% (approx)

Hence 95% of the values are between 40 to 60.
