Zach began at 0.2 for the price of one piece of gum on the number line. Has moved eight times. The whole price is $1.60.

Since each hash mark is worth.2, moving eight times will result in 1.6, or eight times $0.20.

This is further explained below.

Generally, A number line is a depiction of a graded straight line that is used to represent real numbers visually.

It is assumed that every point on a number line corresponds to a real number and that every real number corresponds to a point.

A horizontal line with evenly spaced numerical increments is referred to as a number line.

How the number on the line may be answered depends on the numbers present. How a number is utilized depends on the issue it is associated with, such as when graphing a point

In conclusion, On the number line, Zach started at 0.2, which was equal to the cost of one piece of gum. Has relocated a total of eight times. The whole cost is a dollar and sixty cents.

Moving eight times will result in 1.6, which is equal to eight times $0.20, given that each hash mark is worth.2.

Joanne deposits $4,300 into a l-year CD at a rate of 2.3%, compounded daily.

a. What is her ending balance after the year, to the nearest cent?

b. How much interest does she earn, to the nearest cent?

c. What is her annual percentage yield to the nearest hundredth

Remember that

The compound interest formula is equal to

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest  in decimal

t is Number of Time Periods

n is the number of times interest is compounded per year

in this problem we have

P=$4,300

t=1 year

r=2.3%=2.3/100=0.023

n=365

Part a

Find out the value of A

substitute the given values in the formula

A=$4,400.04

Part b

I=A-P

I=4,400.04-4,300

I=$100.04

Part c

we have

4,300 -----> represent 100%

so

Applying proportion

Find out how much percentage is 4,400.04

100/4,300=x/4,400.04

x=(100/4,300)*4,400.04

x=102.33%

therefore

102.33-100=2.33%

Probability - The value of P(AUB) =  0.557

What is Probability ?

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

Given,

P(A) = 0.2,

P(B) = 0.31 and

P(A/B) = 0.152,

Since, we know that

P(A⋃B) = P(A)+P(B)-P(A⋂B)

So, we have to find P(A⋂B)

We know that,

P(A/B) = P(A⋂B)/P(B)

Putting the values we get,

0.152 = P(A⋂B) / 0.31

P(A⋂B) = 0.152 x 0.31

P(A⋂B) = 0.047

Now, lets find the value of P(A⋃B)

P(A⋃B) = P(A)+P(B)-P(A⋂B)

Putting the values we get,

P(A⋃B) = 0.2 + 0.31 + 0.047

P(A⋃B) = 0.557

Hence the value of P(A⋃B) = 0.557

Step-by-step explanation:

debemos de usar la ecuacion dy/dx

The interest paid on the loan and the total amount paid are $84,320 and $152,320 respectively.

It is given in the question that:-

Money borrowed by the company (Principal) = $68,000

Time period for which the money is borrowed = 8 years

Simple Interest rate = 15.5 %

We have to find the interest paid on the loan and the total amount paid.

We know that,

Simple interest = (Principal * Interest * Rate)/100

Hence, we can write,

Simple interest = (68000 * 15.5 * 8)/100 = $84,320

Also, we know that,

Amount = Principal + Interest

Hence, we can write

Amount = 68,000 + 84,320 = $152,320

The complete question is added as an attachment

From the attached question, we have the following parameters

P(White Vehicle) = 0.25

P(Car) = 0.36

P(White Car) = 0.08

Using the complement rule of probability, we have the following equation

P(White Car) + P(Not White Car)  = 1

Substitute the known values in the above equation

So, we have the following equation

0.08 + P(Not White Car)  = 1

Subtract 0.08 from both sides of the equation

So, we have

P(Not White Car)  = 1 - 0.08

Evaluate the difference

P(Not White Car)  = 0.92

Hence, the probability that the next car will not be a white car is 0.92

The graph of the linear equation:

y = -3x + 4

Can be seen in the image at the end.

Here we know that the equation for the line is:

y = k*x + 4

We know that this line goes through the point (2, -2), then we can replace these values in the above line so we get the value of k.

-2 = k*2 + 4

With this, we can find the value of k.

-2 - 4 = k*2

-6 = k*2

-6/2 = k = -3

Then the line is:

y = -3*x + 4

If we evaluate in x = 0, we get:

y = -3*0 + 4 = 4

So, at this point we know that the line passes through points (0, 4) and (2, -2), so to graph the line, we just need to graph these two points and draw a line that connects them, like in the example below.

The area in square units of the hexagon will be 12√3.

What is Hexagon?

A polygon with six sides are called a hexagon.

Given that;

Jennifer makes a hexagon by arranging 6 equilateral triangles.

The length of one side of a triangle is 4.

Now, To find the area of hexagon, we find the height of the equilateral triangle and then multiply by the 6.

So, In ΔABC;

AB = BC = CA = 4

Then, Measure of DC = BD = 2

Now, using Pythagoras theorem to find height of triangle (AD) as;

AD² = AC² - DC²

AD² = 4² - 2²

AD² = 16 - 4

AD² = 12

Take square root both side;

AD = √12

AD = 2√3

So, The area of hexagon = 6 × Height of triangle

                                      = 6 × 2√3

                                      = 12√3

Considering the expression of a line, the statements:

about the line that passes through (-2, 0) and (2, -4) are true.

A linear equation o line can be expressed in the form y = mx + b

where

Knowing two points (x₁, y₁) and (x₂, y₂) of a line, the slope m of said line can be calculated using the following expression:

m= (y₂ - y₁)÷(x₂ - x₁)

Substituting the value of the slope m and the value of one of the points in the expression of a linear equation, y = mx + b, the value of the ordinate to the origin b can be obtained.

Being (x₁, y₁)= (-2, 0) and (x₂, y₂)= (2, -4), the slope m can be calculated as:

m= (-4 - 0)÷(2 - (-2))

m= (-4)÷ 4

m= -1

Considering point 1 and the slope m, you obtain:

0= -1×(-2) + b

0= 2 +b

-2= b

Finally, the equation of the line that passes through the pair of points (-2,0) and (2,-4) is y= -x -2, wich has a slope of -1. The line intersects the x-axis at (−2, 0).

If x=0, you get:

0= -x -2

2= -x

2÷ (-1)=x

-2= x

The first five terms of the given sequence are 4, 1, 6, 13, 22

We can solve this problem by following a few steps.

The formula to find the next four terms is, a =  (n)²- 3, (n ≥2) as per the question.

Where n is the sequence of the number ( n = 2, 3, 4, 5, 6, etc. )

So, for the 2nd term A₂ = 2² - 3 = 4 - 3 = 1  [As n = 2 for the second term ]

Similarly, for the 3rd term A₃ = 3² - 3 = 9 - 3 = 6  [ As n = 3 for the third term ] ,

for the 4th term A₄ = 4² - 3 = 16 - 3 = 13  [ As n = 4 for the second term ] ,

for the 5th term A₂ = 5² - 3 = 25 - 3 = 22  [As n = 5 for the second term ]

The number of iPhones that should be sold in 2017 (since growth is exponential) is $ 6,476,635 x 10⁶. See the explanation below.

Exponential growth is a data pattern that exhibits greater increases with time. Compounding produces exponential profits in finance. Compounding interest savings accounts may provide exponential growth.

The calculation for the above solution is as follows:

Recall that the formula for exponential growth is:

f(x) = a (1+r)ˣ

Where:

f(x) = exponential growth function

a = initial amount

r = growth rate

{x} = number of time intervals

Hence f(x) = 1.7 (1+ r)⁵

Note that x = 2017-2012 =5

r = (present value - past value)/ past value

Present value = 35.2

Past Value = 1.7

Hence r = (35.2-1.7)/1.7

r = 19.7058823529

Approximately 19.71

Hence,

f(x) = 1.7 (1+ 19.71)⁵

= 1.7 (20.71)⁵

= 1.7 x 3809785.2361

= 6476634.90137

Which is approximately = 6,476,635
