Step-by-step explanation:

Angles in a triangle add up to 180 degrees always, you already have two angles. Subtract those two angles from 180 then you have 75. A straight line always equals 180, and since we just found one angle on that line which is 75, just subtract 75 from 180 to get the answer.

    A line's x-intercept and y-intercept are the points at which the x- and y-axes, respectively, are crossed. We find it easier to graph linear equations when we consider intercepts.

    Where a line on a graph crosses the x-axis is known as the x-intercept. At that time, the y coordinate's value is zero. For instance, the x-intercept would be where the equation y = x + 5 crosses the x-axis at the location (-5, 0).

      We set y = 0 and solve the equation for x to determine the x-intercept. This is due to the fact that the line crosses the x-axis at y=0. If an equation is not in the form y = mx + b, we can still solve for the intercepts by substituting 0 where necessary and then solving for the final variable.

        This is an illustration of a y-intercept. Think about the line y = x + 3. The point where this graph crosses the y-axis is (0,3). Therefore, the y-intercept of the line y = x+ 3 is (0,3).

       If you can locate the x-intercept of a linear function, finding the zero should be simple. The x-coordinate of the x-intercept is zero.

Summary

         Consider the numbers as being on the x-axis to help you remember this. The positive values are located to the right of the origin, and the negative values are located to the left of the origin.

Proportionately, the total number of registered doctors, based on the ratio of female doctors, is 150,637.

Proportion refers to the quantity relationship of a variable contained in another.

Using proportion, two values are equated to each other.

For instance, we equate the percentage of registered female doctors to the number of registered female doctors.

Proportions, like ratios, are stated as fractions, decimals, or percentages because they depict the portion of a variable in another.

The ratio of registered female doctors = 31.4%

The number of registered female doctors = 47,300

31.4% = 47,300

100% = 47,300/31.4% x 100

The total number of registered doctors = 150,637  (47,300/31.4%)

Thus, the total number of registered doctors is 150,637, given that 47,300 female registered doctors proportionately represent 31.4% of the population.

ANSWER

The arithmetic sequences are: I and iii

EXPLANATION

The formula for the nth term of an arithmetic sequence is:

where a1 is the first term of the sequence and d is the common difference.

For the first sequence I. 2, 4, 6, 8, 10... we can find the common difference by subtracting the first term from the second:

So the nth term of this sequence is:

Each term of this sequence follows this rule. Therefore this is an arithmetic sequence.

For the second sequence II. 2, 4, 8, 16, 32... there's no common difference because between the first and second term there's a difference of 2, between the second and third there's a difference of 4, and this increases as we move through the sequence. Therefore this is not an arithmetic sequence.

For the third one, III. a, a+2, a+4, a+6, a+8... we can see that there is a common difference:

The rule for the nth term is:

Let's find the first 5 terms:

This shows that each term follows the same rule. Therefore this is an arithmetic sequence.

A percentage is a number or ratio that represents a fraction of 100. 

If there is a trade discount of 45% on the price of the merchandise of $5900, the net price of the merchandise is $3245.

A percentage is a number or ratio that represents a fraction of 100. 

We have,

Merchandise price = $5,900

Discount rate = 45%

45% = 45/100 = 9/20

The net price of the merchandise:

= 5900 - (45% of 5900)

= 5900 -  9/20 x 5900

= 5900 - 9 x 295

= 5900 - 2655

= 3245

Final answer:

Hence, the set of the point from the given system of inequality is shown below:

Answer:

[tex]y=\frac{-1}{3}x+5[/tex]

Answers being -1/3 and 5

Step-by-step explanation:

In slope-intercept form, you seem to be missing your slope and intercept.  Luckily, the graph has everything you need.

Recall slope is rise over run or y over x.

[tex]m=\frac{y2-y1}{x2-x1}[/tex]

The slope of this line can be determined by counting the x and y movements of the line between two intersections where it evenly collides.  For instance, between (0,5) and (3,4), the line moves right three and down one.  

This would give you a slope of -1/3.

Another way to find the slope is to choose any two points and use the slope formula above.  Using those same two points:

[tex]m=\frac{4-5}{3-0}[/tex]

[tex]m=\frac{-1}{3}[/tex]

Now you have the first part of your answer.  The slope is -1/3.

The second part is the y coordinate of the y-intercept.  In this case, the graph includes the intercept, which we can clearly determine is (0,5).  Therefore, your second answer would be 5.

The full answer being [tex]y=\frac{-1}{3}x+5[/tex].

The length of the three sides of the triangle are 11 feet, 12 feet and 15 feet.

A triangle is a polygon with three sides.

The perimeter of a triangle is 38 feet.

The perimeter of the triangle is the sum of the whole three sides.

One side of the triangle is one foot longer than the second side.

let

the second side = x

longer side = x + 1

The third side is four feet longer than the second side.

Hence,

Third side = 4 + x

Therefore,

38 = x + x + 1 + x + 4

38 = 3x + 5

3x = 38 - 5

3x = 33

x = 33 / 3

x = 11

Brief history of triangle numbers

What is Triangle Number?

An equilateral triangle-shaped group of objects is counted using a triangular number or triangle number. Square and cube numbers are two further examples of figurate numbers, which also include triangle numbers.

Students are typically introduced to triangular numbers through the account of Carl Gauss, a well-known mathematician who used the concept of the triangle number formula to aid him with summing consecutive integers as a student. This tale and its applications in many situations are discussed in the article Clever Carl.

Triangular numbers were created by the Pythagoreans, who discovered connections between geometric forms and numbers, giving rise to triangular, square, pentagonal, and other numbers.

After four or five terms, students may recognize that the answer can be discovered by adding consecutive terms, according to our research. As an illustration, you may use the formulas 1+2+3+4+5 or 10 (the preceding term) + 5 to determine the fifth term. However, when students attempt to transition from this to the general formula for triangle numbers of

n(n+1)/2

Drawing triangle numbers is an exercise that could be helpful in establishing a connection between these two concepts.

The nth term and substitution into algebraic expressions can then be discussed using this formula. Sequences, notably quadratic sequences, can also be discussed.

The probability of having female baby is 0.95

What is probability?

Probability is a discipline of mathematics that deals with statistical models of how probable an event is to exist or how likely a statement is to be true. The probability of an occurrence is a value between 0 and 1 and 1, where 0 denotes the event's impossibility and 1 represents certainty. The greater the likelihood of an occurrence, the more probable it will occur. Tossing a fair (unbiased) coin is a basic example. Because the coin is fair, the two possibilities ("heads" and "tails") are equally likely; the chance of "heads" equals the probability of "tails," and because no other outcomes are possible, the probability of either "heads" or "tails" is 1/2.

The probability of having female baby is = 284/(284 + 15) = 0.95

1. Let the unknown negative number be x

The square of the negative number: x² is

Sixteen more than six times of negative x: 6x+16

It is written as: (x)²=6x+16

Equating to zero, we have:

x²-6x-16=0

Factorizing, we have:

x²-8x+2x-16=0

x(x-8)+2(x-8)=0

x+2=0 and x-8=0

x=-2 and 8

Since the number is negative, x = -2

Therefore, the value of the negative number is -2

2. Given:

Sum of two numbers = 23

Product of two numbers = 120

Calculation:

Let the two numbers be x and y

x+y=23...............equation 1

xy=120..................equation 2

From equation 1, x=23-y

Substitute the value of x in equation 2, we have:

(23-y)y=120

Opening the brackets, we have:

23y-y²=120

Rearranging the equation, we have:

-y²+23y=120

Equating to zero, we have:

-y²+23y-120=0

Multiplying both sides by (-1), we have:

y²-23y+120 = 0

Factorizing, we have:

y²-15y-8y+120=0

y(y-15)-8(y-15)=0

(y-8)(y-15)=0

y=8 or 15

Substituting the values of y in any of the equation. Choosing equation 1, we have:

From Equation 1: x+y=23

When y=8,

x+8=23

x=23-8

x=15

When y=15

x+15=23

x=23-15

x=8
