[tex]\begin{gathered} 47\cdot2\colon3\cdot2 \\ 94\colon6 \end{gathered}[/tex]In a recent year, 31.4% of all registered doctors were female. If there were 47,300 female registered doctors that year, what was the total number of registered doctors?
Proportionately, the total number of registered doctors, based on the ratio of female doctors, is 150,637.
What is proportion?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.

How can you find complex roots using Descartes' Rule of Signs?
We may determine the total number of positive + negative real roots using the rule of signs. We may get the potential number of complex roots by deducting this total from the polynomial's degree.
An imaginary integer is referred to as an imaginary zero if it produces a zero output when plugged into a polynomial (or a complex zero).

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.
What is a good x-intercept illustration?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).
How do you calculate the math x-intercept?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.
What is an illustration of intercept?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).
The x-intercept is zero, right?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.
The x-intercept can be positive or negative, but how do you know?Summary

Solve the quadratic equation X^2+5x+6using the completing the square method. Be sure to explain each step.
We must solve the following quadratic equation by completing squares:
[tex]x^2+5x+6=0.[/tex]1) First, we rewrite the equation in the following way:
[tex]x^2+2\cdot\frac{5}{2}\cdot x+6=0.[/tex]2) We sum to both sides of the equation (5/2)², get:
[tex]x^2+2\cdot\frac{5}{2}\cdot x+(\frac{5}{2})^2+6=(\frac{5}{2})^2.[/tex]3) Expressing the first term as a square, we have:
[tex](x+\frac{5}{2})^2+6=\frac{25}{4}.[/tex]4) Passing the +6 at the left as -6 at the right:
[tex]\begin{gathered} (x+\frac{5}{2})^2=\frac{25}{4}-6, \\ (x+\frac{5}{2})^2=\frac{25}{4}-\frac{24}{4}, \\ (x+\frac{5}{2})^2=\frac{1}{4}. \end{gathered}[/tex]5) By taking the square root on both sides, we get two solutions:
[tex]\begin{gathered} x+\frac{5}{2}=+\frac{1}{2}\rightarrow x=\frac{1}{2}-\frac{5}{2}=-\frac{4}{2}=-2, \\ x+\frac{5}{2}=-\frac{1}{2}\rightarrow x=-\frac{1}{2}-\frac{5}{2}=-\frac{6}{2}=-3. \end{gathered}[/tex]Answer1) Re-writing the equation:
[tex]x^2+2\cdot\frac{5}{2}\cdot x+6=0.[/tex]2) Summing (5/2)² on both sides:
[tex]x^2+2\cdot\frac{5}{2}\cdot x+(\frac{5}{2})^2+6=(\frac{5}{2})^2.[/tex]3) Expressing the first term as a square:
[tex](x+\frac{5}{2})^2+6=\frac{25}{4}.[/tex]4) Simplifying:

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.
How to find the length of a triangle?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
Therefore, the sides of the triangle are 11 ft, 12 feet and 15 ft.

Can someone help me make a floor plan using the shapes on the scale factor sheet?
Answer:
k = 4
Explanation:
1) The triangles in example 1 are similar triangles but differs in size
We are to calculate the scale factor k
Using the formula
Scale factor k = size of the larger triangle/size of the smaller trinagle
Since they are similar triangles;
k = DF/AB
Given
DF = 48
AB = 12
Substitute the given values into the expression for k above to have;
k = 48/12
k = 4
Hence the scale factor from triangle ABC to DEF is 4
