With the help of binomial distribution we can conclude our answer.
What is binomial distribution?The binomial distribution with parameters n and p is the discrete probability distribution of the number of successes in a series of n independent experiments, each asking a yes-or-no question and having its own Boolean-valued outcome: success (with probability p) or failure (with probability displaystyle q=1-pq=1-p). This distribution is used in probability theory and statistics. A Bernoulli trial, or experiment, is another name for a single success-or-failure experiment, and a Bernoulli process is another name for a series of results. For a single trial, or n = 1, the binomial distribution is a Bernoulli distribution. The popular binomial test of statistical significance is based on the binomial distribution. [1]A sample of size n drawn with replacement from is widely used to model the number of successes using the binomial distribution.acc to our question-

(a) What is the slope of a line parallel to it?
(b) What is the slope of a line perpendicular to it?
(a) The slope of a line parallel to it is. (Simplify your answer.)
(b) The slope of a line perpendicular to it is
(Simplify your answer.)
a. The slope of the line that is parallel to y = 5/8x + 9 is: 5/8.
b. The slope of the line that is perpendicular to y = 5/8x + 9 is: -8/5.
What is the Slope of Parallel and Perpendicular Lines?When two lines are parallel to each other, the lines will have the same slope value (m). However, if both lines are perpendicular to each other, they would have slope values that are negative reciprocals, meaning the product of their slope would be -1.
a. Given the equation, y = 5/8x + 9, the slope (m) of the line is 5/8.
Therefore, it implies that the line that is parallel to y = 5/8x + 9 will have a slope that is the same as 5/8.
Thus, the slope of the parallel line to the equation, y = 5/8x + 9, is: 5/8.
b. The negative reciprocal of 5/8 is -8/5.
Therefore, the slope of the line that is perpendicular to y = 5/8x + 9 would be: -8/5.

The length and width of a rectangle that maximises the enclosed area are 800 yards. The maximum area is 640,000 square yards.
In the given question we have to find the maximum area of the rectangular area.
Liana has 3200 yards of fencing to enclose a rectangle.
As we know that the perimeter of rectangle
P= 2(l+b)
Let length of the rectangle is x yards and width is y yards.
So the equation should be
2(x+y) = 3200
Divide by 2 on both side we get
x+y = 1600................(1)
From the area of rectangle is
A = xy
From the equation the value of y is 1600-x.
Now putting the value of y
A = x(1600-x)
A = 1600x-x^2
On differentiating
dA/dx = 1600-2x
Putting dA/dx=0
1600-2x=0
Subtract 1600 on both side we get
-2x= -1600
Divide by -2 on both side we get
x = 800 yards
Now putting the value of x in the y=1600-x
y=1600-800
y=800 yards
So the maximum area is
A= 800*800
A= 640,000 square yards
Hence, the length and width of a rectangle that maximises the enclosed area are 800 yards. 640,000 square yards is the maximum area.

Identify the correct property of equality to solve each equation. 3 x = 27 x 6 = 5
The correct property of equality to solve each equation. 3 + x = 27 and x + 6 = 5 is subtraction property of equality.
The property of equality defines an equivalence relationship between two variables. The subtraction property of equality refers to the property that two sides of the equation remain equal when the same number is subtracted from both sides of an equation. According to the subtraction property of equality, if two quantities a and b are equal, and if c is subtracted from both a and b, then the difference of a and c and the difference of b and c are equal. Hence, if a = b, a – c = b – c. Using the subtraction property of equality:
3 + x = 27
3 + x -3 = 27 - 3
x = 24

The magnitude and direction of two forces acting on an object are 70 pounds, S76°E, and 120 pounds, N80°E, respectively. Find the magnitude, to the nearest
hundredth of a pound, and the direction angle, to the nearest tenth of a degree, of the resultant force.
The magnitude is approximately
pounds.
(Do not round until the final answer. Then round to the nearest hundredth as needed.)
The magnitude is approximately 186 pounds.
What is meant by magnitude?A mathematical object's magnitude, often known as its size, is a quality that indicates whether it is bigger or smaller than other things of the same sort. Formally speaking, an object's magnitude represents the ordered (or ranked) outcome of the class of objects it belongs to.
We have to assume that the notation starts South and then moves 76 degrees East.
The 70-pound force is going at an angle down and to the right.
The down one is negative and the right one is positive.
We have to use the vectors as the hypotenuse of a rectangle.
70 cos(76) = vertical = 16.93 down
70 sin(76) = horizontal = 67.92 right
120 cos(80) = vertical = 20.83 up
120 sin(80) = horizontal =118.17 right
We have to add up all the values vertically and horizontally, and we get
-16.93 + 20.83 =3.9 up
67.92 + 118.17= 186.09 right
Here, the magnitude is the hypotenuse.
sqrt(15.21+34629.49) =186.13 pounds.
Direction is cos⁻¹(3.9/186.13) = 88.802
Remember this is North then 88.802 degrees East
