The probability that at least four of the 25 patients actually have the flu is 0.013
What is Probability?Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.
The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.
The degree to which something is likely to happen is basically what probability means.
The probability P(X ≥ 4).
By De Morgan's Law, this is equal to 1-P(X<4).
If we add up the values of x=0,1,2,3 from our pmf,
[tex]$p_x = \binom{25}{x}(0.04)^x(1-0.04)^{25-x}$[/tex]
So, x=4
P(4) = 25! / 4! ( 25- 4)! x [tex]0.04^4[/tex] [tex](1 - 0.04)^{25- 4}[/tex]
P(4) = 0.013
Hence, the probability that at least four of the 25 patients actually have the flu is 0.013

Find any solutions of x/x-1 + 2/x+2= -6/x^2+x-2
Answer:
a I think ooookkkkk
The solution of the equation x/(x-1) + 2/(x+2) = -6/(x²+x-2) represented by statement is option D. The equation has one true solution and one extraneous solution.
To find the solutions to the equation, we need to simplify and solve for x:
x/(x-1) + 2/(x+2) = -6/(x²+x-2)
Factor the denominators on both sides of the equation.
The denominator on the left side can be factored as follows:
x² + x - 2 = (x+2)(x-1)
Find the common denominator.
The common denominator for the left side is (x-1)(x+2).
Rewrite the fractions with the common denominator:
[(x+2) × x]/[(x-1)(x+2)] + [2 × (x-1)]/[(x-1)(x+2)] = -6/[(x+2)(x-1)]
Combine the fractions,
[x(x+2) + 2(x-1)] / [(x-1)(x+2)] = -6/[(x+2)(x-1)]
Eliminate the denominator:
Multiply both sides by (x+2)(x-1) to eliminate the denominators:
[x(x+2) + 2(x-1)] = -6
Expand and simplify the equation:
x² + 2x + 2x - 2 = -6
x² + 4x - 2 = -6
x² + 4x + 4 = 0
Solve for x using the quadratic formula:
x = (-b ± √(b²-4ac)) / 2a
Here, a = 1, b = 4, and c = 4.
x = (-4 ± √(4² - 4 × 1 × 4)) / 2× 1
x = (-4 ± √(16 - 16)) / 2
x = (-4 ± √0) / 2
x = (-4 ± 0) / 2
x = -4 / 2
x = -2
The equation has one true solution, x = -2 (repeated root).
Now, let's check this solution in the original equation:
x/(x-1) + 2/(x+2) = -6/(x²+x-2)
(-2)/((-2)-1) + 2/((-2)+2) = -6/((-2)²+(-2)-2)
(-2)/(-3) + 2/0 = -6/(4-2-2)
2/0 is undefined, and since we cannot divide by zero, we have an extraneous solution.
Therefore, the correct statement for the solution is option D. The equation has one true solution and one extraneous solution.

x² - 20x - 12 = 0Step-by-step explanation:
One root is given, 10 - 4√7.
Since the polynomial has to have rational roots and of a minimal degree, the other root is the conjugate of the given and the polynomial is of degree 2 minimum.
The polynomial is:
(x - 10 - 4√7)(x - 10 + 4√7) = 0x² - (10 - 4√7 + 10 + 4√7)x + (10² - (4√7)²) = 0x² - 20x + 100 - 112 = 0x² - 20x - 12 = 0What is the quotient of 3/4 and 5/6

a reduced fat cookie contains 11g of fat per serving. in order for food to be termed 'reduced fat', it must have at least 20% less fat than the regular item. what can conclude about how much fat is in a serving regular cookie?
Personally, I did this in a kinda weird way but I think that it should be correct
-How I figured the answer out-
I took 11g and wrote 80% next to it, because after all it has 80% less fat than the regular cookie.
Then, I scaled it down to 10% by dividing by 8, which got me
1.375g = 10%
And finally, I multiplied by 10 to now have 100% (meaning, a regular serving size cookie) and be left with the result: 13.75g
-The answer-
13.75g (don't forget to write the units)

What is the advantage of paying your credit card balance in full each month?
You will incur only a small "paid in full" fee on your next credit card statement.
You pay only a small amount of interest.
You have less of your credit limit available, therefore, less temptation to spend.
You avoid paying any interest and fees.
Answer:
D
You avoid paying any interest and fees, this is the most obvious since you are trying to avoid debt and fees which will build up as you don't pay them
Write an equation (any form) for the quadratic graphed below:
Vertex is (2,3), so that gives us:
y=a(x-2)^2+3
Now the graph goes through (0,1), so plug that in to find a:
1 = a(0-2)^2+3
-2 = a(-2)^2
-2 = a•4
-1/2 = a
So, y = -1/2 (x-2)^2 + 3
Answer:
y = - ½(x - 2)² + 3
Step-by-step explanation:
Given the vetex, (2, 3), as the maximum point on the graph, along with the y-intercept, (0, 1):
We can substitute these values into the given vertex form of the quadratic equation:
y = a(x - h)² + k
where:
a = determines whether the graph opens up or down, and makes the parent function wider or narrower. If a is positive, the graph opens up; if a is negative, the graph opens down. If 0 < a < 1, the graph is wider than the parent function. If a > 1, the graph is narrower than the parent function.(h, k ) = vertexh = determines how far left or right the parent function is translated.k = determines how far up or down the parent function is translated.Use vertex = (2, 3) and y-intercept (0, 1) to solve for "a":
y = a(x - h)² + k
1 = a(0 - 2)² + 3
1 = a(-2)² + 3
1 = a(4) + 3
Subtract 3 from both sides:
1 - 3 = a(4) + 3 - 3
-2 = 4a
Divide both sides by 4 to solve for a:
-2/4 = 4a/4
- ½ = a
Therefore, the value of a = - ½. This means that the graph opens downward, and that the parabola is wider than the parent function.
The quadratic equation in vertex form given a = - ½, and vertex (2, 3) is:
y = - ½(x - 2)² + 3

Use the point and the slope to graph each line. Write the equation of the line.
The line passes through point (4,0) and has slope 0.5.
Answer:
slope = 0.5=1/2
using the formula y-y1 = m (x -x1)
y - 0 =1/2(x - 4)
y = 1/2 (x -4); cross multiply
2y = x -4
divide both sides by 2
y = 1/2x -2
y = 0.5x -2(equation of the line)
