a company has a workforce of 200 employees. 120 of the employees are men and the rest are women. if 10 employees are randomly selected, what is the probability that at least 4 of them are women?
The probability that at least 4 of the 10 selected employees are women is approximately 0.671.
Let the probability that a randomly selected employee is a woman is "p",
The 120 employees are men and rest 80 are women,
We have,
⇒ p = (number of women)/(total number of employees),
⇒ p = (200 - 120)/200,
⇒ p = 0.4,
Let X = number of women among the 10 employees selected.
Then X follows a binomial distribution with parameters "n = 10" and "p = 0.4".
The probability of "at-least-4" selected employees are women is expressed as⇒ P(X ≥ 4) = 1 - P(X ≤ 3),
⇒ P(X ≤ 3) = [tex]\[ \sum_{k=0}^{3} \][/tex] C(10,k) × 0.4^k × 0.6^(10-k),
We can then subtract this value from 1 to obtain P(X ≥ 4),
⇒ P(X ≥ 4) = 1 - P(X ≤ 3),
⇒ P(X ≥ 4) ≈ 0.671
Therefore, the required probability is approximately 0.671.

What is the value of n? enter your answer in the box.
The value of "n" is 6.
"n" is related to a circle with intersecting chords labeled 5, n+4, 7, and n+8 [1]. To find the value of "n", we can use the property that states that if two chords intersect inside a circle, the products of their segments are equal. Using this property, we can set up the following equation:
7(n+4) = 5(n+8)
Expanding the brackets, we get:
7n + 28 = 5n + 40
Simplifying, we get:
2n = 12

The function is defined by this set of rules and we got the cost of mailing a letter weighing 2.5 ounces from the United States to Mexico in 2018 using function P is $2.89.
Based on the rules, the function P is defined as follows:
P(w) = 1.15, if 0 < w ≤ 1
P(w) = 1.99, if 1 < w ≤ 2
P(w) = 2.89, if 2 < w ≤ 3
P(w) = 3.30 + 0.45(w-3), if 3 < w
This function gives the cost, in dollars, of mailing a letter from the United States to Mexico in 2018 based on the weight of the letter in ounces, w.
To find the cost of mailing a letter weighing 2.5 ounces using function P, we need to evaluate P(2.5). Based on the rules defined above, we can see that 2 < 2.5 ≤ 3. Therefore, the cost of mailing a letter weighing 2.5 ounces would be:

Answer:
x = z = 3√5y = 4Step-by-step explanation:
You want the missing segment lengths in the kite shown, where half-diagonals are 3 and 6, and one side length is 5.
KiteThe diagonals of a kite cross at right angles, so each of the triangles shown is a right triangle. The figure has left-right symmetry about the vertical axis, so x=z.
Length yWe recognize the top triangles as being 3-4-5 right triangles, so the missing side length is y = 4.
Lengths x and zThese lengths are the hypotenuse of a right triangle with legs 3 and 6. The Pythagorean theorem tells us they are ...
x² = 3² +6²
x² = 9 +36 = 45
x = √(45) = √(9·5) = 3√5
The lengths x and z are ...
x = z = 3√5

Additional comment
In case you have never heard of a 3-4-5 right triangle, you can find y from the Pythagorean relation:
5² = 3² +y²
y² = 25 -9 = 16
y = √16 = 4

What is the inverse of the logarithmic function
f(x) = log2x?
f –1(x) = x2
f –1(x) = 2x
f –1(x) = logx2
f –1(x) = StartFraction 1 Over log Subscript 2 Baseline x EndFraction
Answer: The inverse of the logarithmic function f(x) = log2x can be found by interchanging the roles of x and y in the function and solving for y. The steps are as follows:
Step 1: Replace f(x) with y.
y = log2x
Step 2: Interchange x and y.
x = log2y
Step 3: Solve for y.
We need to isolate y on one side of the equation. To do this, we can rewrite the equation in exponential form. Recall that the logarithmic function with base b is defined as follows:
logb(x) = y if and only if b^y = x.
Using this definition, we can rewrite the equation x = log2y as follows:
2^x = y
This means that the inverse of f(x) = log2x is given by:
f –1(x) = 2^x
Therefore, the correct answer is:
f –1(x) = 2^x.

Here, Y and x are related in such a way that there is a distinct value of y for each value of x, and this relationship is frequently represented as y = f(x), or "f of x." In other words, the same x cannot have more than one value for f(x). The domain and range of the function are the set of values of f(x) that are produced by the values in the domain of the function, which is the set of values of x. In addition to f(x), other abbreviated symbols for functions of the independent variable x include g(x) and P(x), especially when the nature of the function is ambiguous or unspecified.
The function is an expression, rule, or law that establishes the relationship between two variables (the dependent variable). In mathematics, functions are everywhere, and they are crucial for constructing physical relationships in the sciences. German mathematician Peter Dirichlet first offered the modern definition of function in 1837.

Two methods for proving that two triangles on a Cartesian coordinate plane are congruent are:
Side-Side-Side (SSS) congruence theorem; and Side-Angle-Side (SAS) congruence theorem.What is the explanation for the above?Two methods for proving that two triangles on a Cartesian coordinate plane are congruent are:
Side-Side-Side (SSS) congruence theorem: Two triangles are congruent if their corresponding sides are equal in length.
Side-Angle-Side (SAS) congruence theorem: Two triangles are congruent if two corresponding sides and the included angle are equal in both triangles.
To prove that two triangles on a Cartesian coordinate plane are congruent using coordinate geometry, we can follow these steps:
Identify the coordinates of the vertices of the two triangles.
Use the distance formula to find the lengths of the sides of each triangle.
Use the angle formula to find the measure of one angle in each triangle.
Check if the corresponding sides and angles of the two triangles are equal.
If the corresponding sides and angles are equal, the two triangles are congruent by SAS or SSS congruence theorem.
Here are the coordinates of the Triangles:
ΔABC = A(-3, 4) B (-4, 1) C (0,3)
ΔDEF = D(0, 2) E(3, 1) F(2, -2)
To prove whether the two triangles ΔABC and ΔDEF are congruent or not, we need to check if their corresponding sides and angles are equal.
Using the distance formula, we can find the lengths of the sides of each triangle:
AB = √[(4 - 1)² + (-4 - (-3))²] = 3.16
BC = √[(3 - 1)² + (0 - 4)²] = 4.47
AC = √[(3 - 4)² + (0 - (-3))²] = 3.16
DE = √[(2 - 1)² + (3 - 0)²] = 3.16
EF = √[(2-3)² + (-2- 1)²] = 3.16
DF = √[(0-2)² + (2 - - 2)²] = 4.47
Thus, on the basis of the side-side-side postulate, both triangles are congruent because the three sides have an equivalent on each triangle.
AB = DE
AC = EF
BC = DF

If she receives $2 off the regular price, p. by using a coupon. her total cost, including 20% for tax and tip, is $9. then the regular price of the lunch special is $11.
Let's figure out why that is so. Romita gets a sushi lunch special at Yoshi's, with a coupon. Romita received a discount of $2 off the regular price, P.
Let's assume that the price of lunch before the discount is $P.
Therefore, after the discount, the cost of the lunch is (P - 2).
Now, let's determine the total cost of the lunch. The price of the lunch is inclusive of 20% tax and tip. This implies that Romita's total cost is 120% of the final cost of the lunch.
We can represent this information in the equation below:
Total cost = 120% of (P - 2)
Total cost = 1.2(P - 2)
From the given information, we know that the total cost is $9.
This means we can solve the equation for P.P = (9/1.2) + 2P = 7.5 + 2P = $11

using diagonals from a common vertex, how many triangles could be formed from a decagon?Answer:_______________
Using diagonals from a common vertex of a decagon (a polygon with ten sides), a total of seven triangles can be formed.
To see why, we can apply the formula for the number of triangles formed by drawing all the diagonals from a single vertex of a polygon, which is (number of sides - 2). For a decagon, the formula gives us:
number of triangles = (10 - 2) = 8
However, we need to subtract one from the total because the vertex where the diagonals are drawn from is not included in any of the triangles. Therefore, the number of triangles formed by drawing diagonals from a common vertex of a decagon is:
number of triangles = 8 - 1 = 7
