A travel bureau estimates that when 20 tourists go to a resort with ten hotels. find the probability that no hotel is left vacant when the first group of 20 tourists arrives.
The solution for this problem is:
One way to solve is to using the "stars and bars" approach, but this could be the other one:
x1 + x2 + x3 + x4 + x5 + x6 + x7 + x8 + x9 + x10 = 20
then use (20+10-1) C(10-1), this will
result to 29C9.
Then find the way to distribute x
as a result, (20-10+10-1) C (10-1) = 19C9
Thus, the probability is 19C9/29C9 or 0.0093

40 POINTS!!!!! A submarine descends to 1/6 of its maximum depth. Then it descends another 2/3 of its maximum depth. If it is now at 650 feet below sea level, what is its maximum depth? Show your work.
Answer:
The maximum is 780.
Step-by-step explanation:
1/6x+2/3x=650
Which is: 1/6x+4/6x=650
5/6x=650
5/6x÷5/6=650÷5/6
x=650 × 6/5
x= 780
The maximum depth the submarine descends to is; 780 ft
Let the maximum depth be x.It descends to 1/6 of max depth = (1/6)x
It descends another 2/3 of max depth = (2/3)x
After descending the depths above, it is now 650 ft below sea level. Thus;(1/6)x + (2/3)x = 650
x(1/6 + ⅔) = 650
x(5/6) = 650
x = 6 × 650/5
x = 780 ft
In conclusion, the maximum depth is 780 ft.Read more about depth below sea level at; https://brainly.com/question/25823081

Is writing a 3 before a square root symbol the same as writing it after a square root symbol?
No, writing a 3 before a square root symbol is not the same as writing it after a square root symbol.
Explanation:No, writing a 3 before a square root symbol is not the same as writing it after a square root symbol. Placing a number before the square root symbol indicates that the number is being multiplied by the square root. For example, 3√x means that the square root is being multiplied by 3. On the other hand, placing a number after the square root symbol indicates that the square root is being taken of that number. For example, √3 means the square root of 3.

Find the measure of angle Q
The value of ∠Q in the figure is 146⁰.
How to determine the value of The value of ∠Q in the figure.
From the figure
Given
∠P = 2x + 10
∠R = 6x - 4
In ∆PQR
∠P + ∠Q + ∠R = 180⁰(sum of angles in triangle)
Substitute
2x + 10 + ∠Q + 6x - 4 = 180
8x + 6 + ∠Q = 180
But m∠P = m ∠R(base angles of issoceles triangle)
2x + 10 = 6x -4
-4x = -14
x = 7/2
Substitute into 8x + 6 + ∠Q = 180
8(7/2) + 6 + ∠Q = 180
28 + 6 + ∠Q = 180
34 + ∠Q = 180
∠Q = 180 - 34
= 146⁰
The value of ∠Q is 146⁰
Marja bicycled 7 hours a day for 14 days. She traveled 294 miles. What is her unit rate of travel per day?
Marja's unit rate of travel per day is calculated by dividing the total miles she traveled (294 miles) by the number of days she biked (14 days). The result is 21 miles per day.
Explanation:The question asks for the unit rate of Marja's travel per day. Unit rate refers to the amount of quantity per one unit of another quantity. In this case, we want to find out how many miles Marja bicycles in a single day.
To calculate this, we need to take the total miles she traveled (294 miles) and divide it by the total number of days she biked (14 days). So, 294 miles ÷ 14 days = 21 miles/day.
This means Marja's unit rate of travel per day was 21 miles.

The ________ is another term for the variance of the sample data. mean square between mean square total mean square within total sum of squares
The term 'mean square within' (MSwithin) refers to the sample variance in a set of data, which is computed by dividing the sum of squares within (SSwithin) by its degrees of freedom. This term is used in ANOVA to estimate how much variation within the sample data is due to chance.
Explanation:The term mean square within (MSwithin) is another term for the variance of the sample data. MSwithin represents the variance within groups.
To calculate this variance, the sum of squares within (SSwithin), which represents the variation within samples that is due to chance, is divided by its respective degrees of freedom.
The variance is a measure of how much the data points in a sample differ from the sample mean.
Variance is calculated by taking the mean of the squared deviations from the mean.
This calculation is often used to determine how spread out the values in a data set are.
In the context of an analysis of variance (ANOVA), the MSwithin is used in conjunction with mean square between (MSbetween), which represents the variance between groups, to calculate the F ratio used for testing the null hypothesis.

The measure of the exterior angle at one base angle of an isosceles triangle is 125 degrees. what is the measure of the vertex angle in degree the measure of the exterior angle at one base angle of an isosceles triangle is 125 degrees. what is the measure of the vertex angle in degrees
Final answer:
To find the measure of the vertex angle in an isosceles triangle, subtract the measure of one of the exterior angles from 180, divide that sum by 2 to find the measure of each base angle, and then subtract one base angle from 180 to find the measure of the vertex angle. In this case, the measure of the vertex angle is 152.5 degrees.
Explanation:
To find the measure of the vertex angle in an isosceles triangle, we can use the fact that the sum of the measures of the interior angles of a triangle is 180 degrees. Since we know that the measure of one of the exterior angles is 125 degrees, we can subtract that from 180 to find the sum of the measures of the other two interior angles. Then, we can divide that sum by 2 to find the measure of each of the base angles. Finally, we subtract the measure of one base angle from 180 to find the measure of the vertex angle.
Let's follow these steps:
Sum of the measures of the other two interior angles = 180 - 125 = 55 degrees
Measure of each base angle = 55 / 2 = 27.5 degrees
Measure of vertex angle = 180 - 27.5 = 152.5 degrees
Therefore, the measure of the vertex angle in this isosceles triangle is 152.5 degrees.

Guys please help! In triangle CDE, the measure of angle C is 90 degrees, side CD is 15 and DE is 3 more than CE. Find the length of the longest side of CDE.
Final answer:
Using the Pythagorean theorem, the length of the longest side of right-angled triangle CDE, which is the hypotenuse DE, is found to be 39 units.
Explanation:
In triangle CDE, angle C is given as 90 degrees, making this a right-angled triangle. According to the information provided, side CD is 15 units long, and side DE is 3 units more than side CE. We are asked to find the length of the longest side, which would be the hypotenuse in a right-angled triangle. To find the hypotenuse, which we'll designate as side DE, we must first establish the relationship between the sides. Let's call CE 'x'; therefore, DE will be 'x + 3'. Since we've established that the triangle is right-angled at C, we can use the Pythagorean theorem, which states that in a right-angled triangle the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the lengths of the other two sides.
So, the equation becomes CD² + CE² = DE², or 15² + x² = (x + 3)². If we solve for 'x' we have:
225 + x² = x² + 6x + 9216 = 6xx = 36As a result, CE = 36 units and DE, the longest side, equals 36 + 3, which is 39 units.
By applying the Pythagorean theorem correctly, we've found that the length of the longest side of triangle CDE is 39 units.
