12620256  different combinations of 31 balloons can be chosen

What are combinations?

Combinations are mathematical operations that count the variety of configurations that can be made from a set of objects, where the order of the selection is irrelevant. You can choose any combination of the things in any order.

From the question, we understand that; a combination of 31 is to be selected. Because the order is not important, we make use of combination.

Also, because repetition is allowed; different balloons of the same kind can be selected over and over again.

So:

n= 31 +8-1 = 38

r=31

Selection =  [tex]^{38}C_{31}[/tex]

Use the formula:

[tex]^{n}C_{r}=\frac{n!}{(n-r)! r!}[/tex]

= > [tex]^{38}C_{31}=\frac{38!}{(38-31)! 31!}[/tex]

[tex]^{38}C_{31}=\frac{38!}{7! 31!}[/tex]

         = [tex]\frac{38*37*36*35*34*33*32*31!}{7*6*5*4*3*2*1* 31!}[/tex]

         = 12620256

The kinematic equation of the motion of the paintbrush dropped 35 feet height from the ground and the 1.85 seconds reaction time of the 6 feet person standing directly below, indicates that they will be hit  by the paintbrush before they can move out of the way.

The kinematic equation of motion describe the motion of a body that moves under constant acceleration, without consideration of the forces causing the body to move.

The height from which the paintbrush is dropped from the roof to the ground = 35 feet

Height of the person standing directly below where the brush falls = 6 feet

The reaction time of the person = 1.85 seconds

The kinematic equation of motion of free fall of an object is presented as follows;

s = u·t + 0.5·g·t²

Where; s = The height through which the paintbrush falls

u = The initial velocity of the paintbrush = 0

g = The acceleration due to gravity ≈ 32.1741 ft/s²

The height the paintbrush falls before meeting the 6 feet tall person, s = 35 feet - 6 feet = 29 feet

Therefore, we get;

29 = 0 × t + 0.5 × 32.1741 × t²

t² = 29 ÷ (0.5 × 32.1741) ≈ 1.803

The time it takes the paintbrush to fall 29 feet, t, is therefore;

t = √(29 ÷ (0.5 × 32.1741)) ≈ 1.343

It takes the paintbrush to reach the height of the person standing directly below in just about 1.3 seconds after it is dropped, before the person can react to move away in 1.85 seconds, therefore, they will be hit by the paintbrush before they can move out of the way.

Rhombus is 4 pairs of congruent sides.

Congruent triangles are triangles that are precisely the same size and shape. The word congruent has the sign ≅. When the three sides and three angles of one triangle match the same dimensions as the three sides and three angles of another triangle, two triangles are said to be congruent.

A rhombus is a parallelogram with four congruent sides.

All the characteristics of a parallelogram are present in a rhombus, plus the following: The diagonals intersect at right angles.

Square and rhombus are the only two quadrilateral shapes that consistently have four congruent sides. Note that congruent sides refer to sides that are of the same length. A quadrilateral having four equal sides and four equal angles is called a square (90 degrees). It combines a rhombus and a right-angled rectangle ( equal side ).

Answer:

Option c) I have 2 and you have 3

The Interest Rates are 2% and 5% respectively

What is Simple Interest?

Simple interest is a quick and straightforward way to calculate the interest on a loan. Simple interest is calculated by multiplying the daily interest rate by the principle multiplied by the number of days between payments.

Solution:

Let, the lesser interest rate be x

Simple Interest = Principal*Time*Rate/100

Total Interest = $166

166 = 2300*x*1/100 + 2400*(x + 3)*1/100

166 = 2300x + 2400x + 7200 / 100

16600 = 4700x + 7200

9400 = 4700x

x = 2%

By means of the law of cosine, the missing side of the triangle has a length of approximately 6.502 units.

Herein we find the case of a triangle with two known side lengths and a known measure of an angle between the two given sides. The measure of the unknown side is determined by the law of cosine, whose definition is shown below:

x² = a² + b² - 2 · a · b · cos θ

If we know that a = 15, b = 12 and θ = 25°, then the equation for the triangle is:

x² = 12² + 15² - 2 · 12 · 15 · cos 25°

Now we proceed to simplify and find the resulting value of x by algebra properties:

x² = 369 - 360 · cos 25°

x² = 369 - 326.271

x² = 42.279

x ≈ 6.502

The length of missing side of the triangle is approximately equal to 6.502 units.

A function formula y = f(x) defines the relation between input values and output values.

We know that the function defines relation between the input values and the output values. A relation is a function if and only of for each input there is exactly one output.

A mathematical equation which involves x and y, i.e., a function, can be written in the form y = an expression involving x

y = f (x).

The function formulas are used for calculating the x-intercept, y-intercept and slope in any function.

We can find the x-intercept of a function by substituting the value of f(x) as 0. Similarly, the y-intercept of a function by substituting the value of x is 0. We can calculate the slope of a linear function by rearranging the function to the form, f(x) = mx + c; where m is the slope and c is the y-intercept.

Therefore, the function formulas are used to determine the x-intercept, y-intercept and slope in any function.

A straight line on the coordinate plane is represented by a linear function.

A linear function always has the same and constant slope.

The formula for a linear function is f(x) = ax + b, where a and b are real values.

Suppose that the linear function is y = mx + c

As per the given, slope m = -4

Put (9,-10)

-10 = -4 x -10 + c

The probability that the sample mean will be less than 318 is 0.0011.

Mean is defined as the average of given numbers i.e. sum of all numbers divided by the total number of numbers. The Mean is denoted as m or μ. Standard deviation is the measure which it shows the variation from the mean exists or not. The standard deviation is denoted as σ.

We know that,

                 P ( x  <  n  )   =   P (   z     <     x  -  μ / ( σ / √n )   )    →   1  

where,     z   =       x - μ / ( σ / √n )  

As per the given question,

                                    P ( x  <  318 ) = ?

Substitute the values in 1,

P ( x < 318 )   =   P ( z < x - μ / ( σ / √n ) )

                      =   P ( z  <   318 - 330 / ( 35 / √80 )

                      =   P ( z < -12 / ( 35 / 8.94 )

                      =   P ( z < -12 / 3.91 )

                      =   P ( z < -3.069 )

                      =   P ( z < -3.07 )

P ( x < 318 )   =   0.0011

Assuming that the population proportion of blue eyes is accurately reflected in each sample, about 380 of the 400 confidence intervals should cover the population proportion.

The confidence interval for the proportion of blue eyes in the population is calculated as follows:

Proportion of blue eyes in the population = sample mean +/- (1.96* Standard Error)

Where Standard Error = sqrt[(proportion of blue eyes in the population)*(1-proportion of blue eyes in the population)/sample size]

At a 95% confidence level, the confidence interval should cover the population proportion 95% of the time. Therefore, 95% of the 400 confidence intervals should cover the population proportion, which is approximately 380 intervals.

The coordinates of the point on the directed line segment from (−3,4) to (3,8) partitions the segment into a ratio of 1 to 3 is given as follows:

(-1.5, 1).

The coordinates of the point are applied using proportions, as the fact that the point partitions the segment into a ratio of 1 to 3 means that the following equation is built:

Point - Initial Coordinate = 1/4(Final Coordinate - Initial Coordinate).

This equation is used to find both the x-coordinate and the y-coordinate of the point.

The x-coordinate of the point is obtained as follows:

x + 3 = 1/4(3 + 3)

x + 3 = 1.5
