The probability of exactly 5 out of the next 10 children getting Huntington's disease is 0.2461, and the probability of exactly 7 getting the disease is 0.1172.
What is the probability?
Probability is the study of the chances of occurrence of a result, which are obtained by the ratio between favorable cases and possible cases.
This problem can be solved using the probability , where we have a fixed number of trials (10 children) and a fixed probability of success (one-in-two chance of getting the disease).
The probability of getting exactly k successes in n trials, each with probability p of success, is given by the binomial probability formula:
P(k) = (n choose k) * [tex]p^k * (1-p)^{(n-k)[/tex]
where (n choose k) is the binomial coefficient, which represents the number of ways to choose k items out of a set of n.
For this problem, we have n = 10, p = 1/2 (since the children have a one-in-two chance of getting the disease), and we want to find P(5) and P(7).
P(5) = (10 choose 5) * ([tex]1/2)^5 * (1/2)^{(10-5)} = 0.2461[/tex] (rounded to four decimal places)
P(7) = (10 choose 7) * [tex](1/2)^7 * (1/2)^{(10-7)} = 0.1172[/tex] (rounded to four decimal places)
Hence, The probability of exactly 5 out of the next 10 children getting Huntington's disease is 0.2461, and the probability of exactly 7 getting the disease is 0.1172.

What are the coordinates of each point after the quadrilateral RSTU is rotated 90 degrees about the origin?
The coordinates of each point after the quadrilateral RSTU is rotated 90 degrees about the origin are R' (2, 1), S' (4, 2), T' = (5, 4), and U' = (3, 3).
What is a rotation?In Geometry, the rotation of a point 90° about the center (origin) in a counterclockwise (anticlockwise) direction would produce a point that has these coordinates (-y, x).
By applying a rotation of 90° counterclockwise to the vertices of triangle RSTU, the coordinates of the vertices of the image are as follows:
(x, y) → (-y, x)
Ordered pair R = (1, -2) → Ordered pair R' = (-(-2), 1) = (2, 1).
Ordered pair S = (2, -4) → Ordered pair S' = (-(-4), 2) = (4, 2).
Ordered pair T = (4, -5) → Ordered pair T' = (-(-5), 4) = (5, 4).
Ordered pair U = (3, -3) → Ordered pair U' = (-(-3), 3) = (3, 3).

Select the inequality that includes the largest number of days this facility can continue to take in cats without exceeding its occupancy limit.
A. x < 5
B. x < 7
C. x < 42
D. x < 36
The highest number of days this institution can continue to accept cats without going over its allowed occupancy is included in the inequality (C) x<42.
What is inequality?An inequality in mathematics is a relation that compares two numbers or other mathematical expressions in an unequal way.
The majority of the time, size comparisons between two numbers on the number line are made.
In mathematics, "inequality" refers to a relationship between two expressions or values that is not equal to each other.
Hence, inequality emerges from a lack of balance.
So, what we can do is add 6 in 285 till it reaches 300.
258 + 6 + 6 + 6 + 6 + 6 + 6 + 6 = 300
6 is added 7 times, then:
6*7 = 42
Then the correct inequality would be x < 42.
Therefore, the highest number of days this institution can continue to accept cats without going over its allowed occupancy is included in the inequality (C) x<42.

The perimeter of a rectangular fence is to be at least 82 feet and no more than 124 feet. If the width of the fence is 14 feet, what is the range of values for the length of the fence?
The range of values for length when the perimeter is between 82 feet and 124 feet is: 27 ≤ l ≤ 48
What is meant by perimeter?A closed path that covers, encircles, or outlines a one-dimensional length or a two-dimensional shape is called a perimeter. The area encircling a two-dimensional figure is known as its perimeter. Whether it is a triangle, square, rectangle, or circle, it specifies the length of the shape. The two primary characteristics of a 2D shape are area and perimeter. The perimeter of the shape can be calculated by summing the measurements of its sides and edges. A rectangle's perimeter is equal to twice the product of its length and width.
Given a rectangular fence.
The perimeter P is at least 82 feet and is no more than 124 feet.
82 ≤ P ≤ 124
The width is 14 feet.
The range of values of the length is to be found.
Now,
Perimeter of rectangle = 2( length + width)
The lowest value of the perimeter is 82
82 = 2(l + 14)
82 = 2l + 28
54 = 2l
l = 27
The highest value of perimeter is 124
124 = 2(l + 14)
124 = 2l +28
96 = 2l
l = 48
Therefore the range of values for length when the perimeter is between 82 feet and 124 feet is:

Graph the system of inequalities. Name the coordinates of the vertices of the feasible region. Find the maximum and minimum of the given function for this region.
Using inequalities, Y(x=0) = -2 and X(y=0) = -2 in region 1.
To pick area 1, draw a line at the intersection of (-2,0) and (0, -2), then choose the right side. such as.
Region 2) To pick the region to the left or upwards in region 2, we must draw a line from (0,2) to (-2,4).
Y(x=0) = 2\sX(y=-2) = -4
Region 3) To pick the region to the right, we must draw a line connecting (-4,0) and (0,4), as I'll demonstrate.
What are inequalities?Inequalities in mathematics describe the relationship between two non-equal numbers. Equal does not necessarily mean unequal. When two values are not equal, we typically use the "not equal symbol ()". However, several inequalities are utilised to compare the numbers, whether it is less than or higher than.
The feasible area is now visible. Let's determine the vertices' coordinates.
Where the blue and green lines intersect is our first vertex.
3x + 2 = x + 4 and y = 3x + 2
3x - x = 4 - 2
y = 3× (1) + 2 = 3 + 2 = 5 when 2x = 2x = 1
(X, Y) = Vertex 1 (1,5)
The intersection of the red and green lines is at vertex #2:
y = -x -2; y = x + 4; y = x + 4 = -x - 2; and y = x + x = -2 - 4
2x = -6, x = -6/2, and y = (-3) + 4 = -3 + 4 = 1 are the results.
(X, Y) = Vertex 2 (-3,1)
The intersection of the red and blue lines is at vertex 3:
y = -x - 2, y = 3x + 2 -x - 2, and y = 2 + 2 -4 x = 4 x = -4 / 4 = -1.
So, y = 3× (-1) + 2 = -3 + 2 = -1
(X, Y) = Vertex 3 (-1, -1)
Let's now modify the graph by including the supplied equation.
The intercept where Y=0 is 0 is given by f(x,y) = -3x + 5y = 0 5y = 3x + 0 y = 3/5 × X + 0
the gradient m = 3/5
A line can be drawn from (0,0) to (-10, -6)
Let's now examine how it would appear in the area where it is practical.
We can see that the function intercepts the blue line or the line of the second section, which is where the largest value is located.
y = 3x + 2 3x + 2 (3/5 - 3) x = 2 -12/5 × x = 2 x = -5/6.
Hence, y = 3x + 2 3/5 × (-5/6) = -1/2.
The maximum is therefore found at (x,y) = (-5/6, -1/2).
The point where the function crosses the red line now marks the minimum.
y = 3/5 × x; y = -x -2
3/5 x = -x - 2\s (3/5 + 1) × x = -2\s8/5 x = - 2\sx = -2× (5/8) = -5/4.
y = 3/5 × (-5/4) = -3/4
The minimum is thus found at (x,y) = (-5/4, -3/4)

803.84 square inches is the surface area of a cylinder with an 8-inch radius and 8-inch height.
What is the surface area of a solid?Any solid shape has a surface area equal to the total of the areas of its faces. For instance, to calculate the surface area of a cuboid, we add the areas of all the rectangles that make it up.
According to the given information:The formula for the surface area of a cylinder is given by:
Surface Area = 2πr² + 2πrh
where r is the radius and h is the height of the cylinder, and π (pi) is a mathematical constant approximately equal to 3.14.
Substituting the given values, we get:
Surface Area = 2 × 3.14 × 8² + 2 × 3.14 × 8 × 8
= 401.92 + 401.92
= 803.84 square inches
the surface area of the cylinder with radius 8 inches and height 8 inches is 803.84 square inches.

Complete the equation of the line through (2,1) and (5,-8) in y=Mx+b form
Answer:
y=-3x+7
Step-by-step explanation:
find the slope which is (y1-y2)/(x2-x1). therefore the slope is -3. and then put it in point slope intercept form which is (y-y1)=m(x-x1) = (y-1)=-3(x-2) and simplified the expression is y=-3x+7.
Problem is down below Please find the answer.
[tex](2x-1)^{2} = 25 \iff (2x-1)^{2} = 5^{2}\\[/tex]
[tex]x > 0 \implies 2x - 1 = 5 \iff 2x = 5 + 1 \iff 2x = 6 \implies \bf x = 3\\[/tex]
[tex](3y-1)^{2} = 36 \iff (3y-1)^{2} = 6^{2}\\[/tex]
[tex]y > 0 \implies 3y-1 = 6 \iff 3y = 6 + 1 \iff 3y = 7 \implies \bf y = \dfrac{7}{3}\\[/tex]
⇒
[tex]\dfrac{3x - y}{x+y} \cdot \dfrac{1}{7} = \dfrac{3(3) - \frac{7}{3} }{7(3+\frac{7}{3} )} = \dfrac{9 - \frac{7}{3} }{7(\frac{16}{3})} = \dfrac{\frac{27-7}{3} }{7(\frac{16}{3})}=\\[/tex]
[tex]= \dfrac{\frac{20}{3} }{\frac{112}{3}} = \dfrac{20}{3} : \dfrac{112}{3} = \dfrac{20}{3} \cdot \dfrac{3}{112} = \dfrac{20}{112} = \bf \dfrac{5}{28}\\[/tex]
