I just answered this with all explanations.

Answer:

960.00

Step-by-step explanation:

Interest = principle x rate x time

interest = 6000 x .04 x 4

960.00

Answer:

I = $ 960.00

Step-by-step explanation:

I = Prt

Since we are figuring out how much money was earned in interest, we will need to convert our R (which is the interest rate) into decimals, which will be, r = R/100 = 4%/100 = 0.04 per year.

Step 1. Divide R by 100, in this case, R is 4, so it will be 0.04.

Step 2. Times 6000 (the money that was deposited) by 0.04, then times it with 4 (the years) and you will get 960.

I = 6000 × 0.04 × 4 = 960

I = $ 960.00

The completed sentences that describe the height reached by the ball specified by the function, f(x), that indicates the balls height, based on the number of bounces, x, f(x) = 64·(0.75)ˣ, which is similar to a geometric progression, is presented as follows;

The variable, x, represents the number of times the ball bounces.

The variable f(x) represents the height of the ball after x bounces.

The parameter, 64, represents the initial height of the ball.

The parameter, 0.75, represent the percentage of height left from each previous bounce.

A geometric progression is a number sequence, arranged such that the ratio between a term and the previous term is a constant, known as the common ratio of the geometric progression.

The exponential function that models the specified situation of finding the height of the ball is presented as follows;

f(x) = 64·(0.75)ˣ

The initial height from which the student drops the ball = 64 feet

The height the ball reaches after one bounce = 48 feet

Height of the ball after 2 bounces = 36 feet

The exponential function, f(x) = 64·(0.75)ˣ, is similar to the equation for a geometric progression, aₙ = a₁·r⁽ⁿ⁻¹⁾

Where;

a₁ = The first term = The initial height

r = The common ratio = 48/64 = 36/48 = 0.75

n = The number of times the ball bounces, in addition to the time the ball is dropped from the initial height, therefore;

x = n - 1, therefore;

x = The number of times the ball bounces

n = x + 1

The terms that complete the sentences are therefore:

The variable that represents the number of time the ball bounces = x

The variable that indicates the height of the ball after x bounces = f(x)

The initial height of the ball = The parameter 64

The percentage of the height the ball bounces to after the previous bounce = 0.75

The difference between the largest and the smallest fraction is 0.24.

A fraction is a component of a whole.

Mathematically, the number is expressed as a quotient, where the numerator and denominator are divided.

In a simple fraction, both are integers.

In a complex fraction, a fraction can be found in either the numerator or the denominator.

A suitable fraction has a numerator that is less than its denominator.

So, first, we will figure out the smallest and the greatest fraction:

We have: 3/5, 5/6, 2/3, 9/8, 7/9 and 3/4

LCM of denominators: 2*2*2*3*3*5 = 360

216/360, 300/360, 240/360, 405/360 (Improper), 280/360, 270/360

Smallest: 216/360

Largest: 300/360

Subtract smallest from largest:

300/360 - 216/360

84/360

7/30

0.2333

Round off: 0.24

Therefore, the difference between the largest and the smallest fraction is 0.24.

Answer:

The answer is 9

Step-by-step explanation:

The given triangle is equivalent triangle

We know that in equivalent triangle all angles are equal to 60°

So,

(7x - 3)° = 60°

7x - 3° = 60°

7x - 3° + 3° = 60° + 3°

7x = 63°

x = 63°/7°

x = 9°

Thus, The value of x is 9°

For Verification Only;

(7x - 3)° = 60°

[7(9) - 3]° = 60°

(63 - 3) = 60°

60° = 60°

Hence,

L.H.S = R.H.S

Answer:

(a) A(w) = w(950-2w) = 950w-2w^2

(b) w = 237.5

(c) A = 112812.5

Step-by-step explanation:

First of all the maximum area is always a square. You can get the answer first to check your work later.

950/4 = 237.5

One side is not needed so add that length to the non-parallel side.

237.5+237.5=475 feet is the length and 237.5 feet is the width(s)

A=475*237.5

A=112812.5 square feet

Doing the algebra...

P=l+2w

950=l+2w

950-2w=l

A=lw

A=(950-2w)w

A=950w-2w^2

The sampling distribution refers to the distribution of the sample mean (X-bar) computed from a set of n independent, normal random variables (X1,...,Xn).

The sampling distribution is a theoretical distribution that describes how the sample mean would vary if you were to take multiple samples from the population and compute the sample mean for each sample. It is based on the assumption that the X1,...,Xn are independently and normally distributed with a common mean and variance.

The sampling distribution is important because it allows us to make inferences about the population mean based on the sample mean. By understanding the properties of the sampling distribution, we can calculate confidence intervals and perform hypothesis tests to determine whether the sample mean is significantly different from the population mean.

In contrast, the distribution on the individual random variables (X1,...,Xn) is the distribution of the individual observations in the sample. The distribution on the means of the individual random variables (Xi) is the distribution of the mean of each individual random variable.

The frequency distribution obtained from a set of n experimental data values is the distribution of the observed data values in the sample.

With the given coordinates (-3, 1) and (0, 4), the slope is 1.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The formula to find the slope of a line is slope = (y2-y1)/(x2-x1)

Here,

1) (-3, 1) and (0, 4)

Δy=(4-1)=3 and Δx=(0(-3))=3

So, m= Δy/Δx =3/3 =1

2) (-6, 27) and (2, 3)

Δy=(3-27)=24 and Δx=(2-(-6))=8

So, m= Δy/Δx =24/8 =3

3) (5, 27) and (0, -8)

Δy=(-8-27)=-35 and Δx=(0-5)=-5

So, m= Δy/Δx =(-35)/(-5) =7

4) (1, 0) and (-7, -24)

Δy=(-24-0)=-24 and Δx=(-7-1)=-8

So, m= Δy/Δx =(-24)/(-8) =3

5) (-3, 20) and (-5, 32)

Δy=(32-20)=12 and Δx=(-5-(-3))=-2

So, m= Δy/Δx =12/(-2) =-6

Δy=(-9-(-4))=-5 and Δx=(0-5)=-5

So, m= Δy/Δx =(-5)/(-5) =1

7) (-8, -2) and (-1, -4.5)

Δy=(-4.5-(-2))=-2.5 and Δx=(-1-(-8))=7

So, m= Δy/Δx = -2.5/7

Step-by-step explanation:

2x + 5y = 12

4x -y = 2  Multiply this through by 5 and then add to the equation above

2ox - 5y = 10  

2x + 5y = 12        

22x = 22  Divide both sides by 22

x = 1

Substiture in 1 for x in either of the two original equations

2x +5y = 12

2(1) + 5y = 12  

2 + 5y = 12  Subtract 2 from both sides

5y = 10  Divide both sides by 5

y = 2

(1,2)

2nd Problem

2x - 5y = 11 Multiply through by 2      4x - 10 y = 22

3x  + 2y = 7    Multiply through by 5    15x + 10 y = 35

Add the two bold equation together

4x - 10y = 22

15x +10y = 35              

19x = 57  Divide both sides by 19

x = 3            

Substitute in 3 for x in one of the original equations to solve for y.          

2x - 5y = 11

2(3) - 5y = 11

6 - 5y = 11  Subtract 6 from both sides
