The value of the car after 3 years is £ 9318.6.

To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is.

First, the value of car after one year

= 18000 x (1- 30%)

= 18000 x 70%

= 18000 x 0.7

= 12600

now, the value of car after two year

= 12600 x (1- 14%)

= 12600x 86%

= 12600x 0.86

= 10836

and, the value of car after three year

= 10836 x (1-14%)

= 10836 x 86%

= £ 9318.6

Hence, the value is £ 9318.6

The common ratio 'r' is not constant, meaning that the series is not geometric.

Each term in a geometric series is created by multiplying the previous term by a fixed constant known as the common ratio.

To determine if the geometric series (4, -7, 49, -343, 16) is convergent or divergent, we need to find the common ratio 'r' of the series.

r = (next term) / (current term)

r = (-7) / 4 = -1.75

r = 49 / (-7) = -7

r = (-343) / 49 = -7

r = 16 / (-343) = -0.0466...

We can see that the common ratio 'r' is not constant, meaning that the series is not geometric, and therefore we cannot determine if it is convergent or divergent.

Answer:

\(P(Invisibility | Female) = \frac{2}{3}\)

Step-by-step explanation:

Given

See attachment for two-way table

Required

Determine \(P(Invisibility | Female)\)

This is calculated using the following formula for conditional probability:

\(P(Invisibility | Female) = \frac{n(Invisibility \& Female)}{n(Female)}\)

From the attached table

\(n(Invisibility \& Female) = 32\)

\(n(Female) = 48\)

So, the equation becomes:

\(P(Invisibility | Female) = \frac{32}{48}\)

Simplify

\(P(Invisibility | Female) = \frac{32/16}{48/16}\)

\(P(Invisibility | Female) = \frac{2}{3}\)

By taking the quotient between the change in the money and the total time in which the change of money happened, we conclude that the  average weekly change is $35/2, so the correct option is B.

The average weekly change will be given by the quotient between the change in the money and the total time in which the change of money happened.

We know that the initial amount of money is $150, and at the end he has $80, so the difference in money is:

d = $80 - $150 = -$70

The negative sign is because the amount of money decreases.

While it happens four weeks after, then the average weekly change in the amount of money is:

A = $70/4 = $35/2

So we conclude that the correct option is B.

The equations are:

M = 21 + 18t

G = 42 + 11t

The page they would be on is 75 pages.

The linear equation that represents the total number of pages read by each person at day t, is :

Total pages read = pages read at the beginning of the month + (number of pages read per day x number of days)

Total pages read by Matthew =   21 + (18 x t)

= 21 + 18t

Total pages read by Guadalupe = 42 + (11 x t)

= 42 + 11t

When they are on the same page, the two above equations would be equal:

21 + 18t = 42 + 11t

18t - 11t = 42 - 21

7t = 21

If we solve  4x-3y=3, -8x +6y=-6 by substitution or elimination, we will have x=3/4 and y=0

We have the following simultaneous equations:

4x-3y=3.....................(i)

-8x+6y=-6..................(ii)

We solve using substitution:

Make x the subject of formula in equation(i):

4x=3+3y

x=(3+3y)/4

Now, replace the value of x in equation(ii)

-8x+6y=-6, and x=(3+3y)/4

-8((3+3y)/4)+6y=-6

-2(3+3y)+6y=-6

-6-6y+6y=-6

y=0

Now, we replace the value of y=0 in any equations we have to find the corresponding value of x:

4x-3y=3, but y=0

4x-3(0)=3

The perfect squares approximation method is a technique used to quickly estimate the square root of a number without using a calculator.

It involves finding the nearest perfect square to the given number, and then using the difference between the two numbers to make an estimate of the square root.

Here's how it works:

Find the nearest perfect square to the number you want to take the square root of. For example, if you want to find the square root of 27, the nearest perfect square is 25.

Subtract the perfect square from the original number. In this case, 27 - 25 = 2.

Take the square root of the perfect square. In this case, the square root of 25 is 5.

Divide the difference you found in step 2 by twice the perfect square root from step 3. In this case, (2 / (2 x 5)) = 0.2.

Add the result from step 4 to the perfect square root from step 3. In this case, 5 + 0.2 = 5.2.

Therefore, the square root of 27 is approximately 5.2.

Note that this method gives an approximate answer and may not be as accurate as using a calculator or other methods. It is useful, however, for quickly estimating the square root of a number.

At Ying Ying's bakery, there's an 8% probability that a customer will report a food allergy.

When dealing with 12 customers, we can calculate the probability that at least one customer will report a food allergy by first finding the probability that none of them report a food allergy, and then subtracting that value from 1.

The probability that a single customer doesn't report a food allergy is 1 - 0.08 = 0.92. For all 12 customers not to report a food allergy, the probability is 0.92^12 = 0.3981 (rounded to four decimal places).

Now, subtract this probability from 1: 1 - 0.3981 = 0.6019.

Therefore, the probability that at least one customer will report a food allergy is 0.6019 or 60.19%.

Parachutist's rate during free fall is 40 meters per second and will fall approximately 490 meters during 10 seconds of free fall.

First, we need to convert 132 feet per second to meters per second. We know that 1 meter is equal to 3.3 feet, so we can use the following conversion factor:

\($\frac{3meter}{3.3 feet}\)

To convert feet per second to meters per second, we can multiply by the conversion factor:

\(132 (\frac{1}{3.3} ) = 40 meters/second\)

Therefore, the parachutist's rate during free fall is 40 meters per second.

Next, we can use the following formula to find the distance the parachutist falls during 10 seconds of free fall:

distance =\(\frac{1}{2}\) * acceleration * time²

where acceleration due to gravity is approximately 9.8 meters/second^2.

Substituting the given values, we get:

distance = \(\frac{1}{2}\) * 9.8 meters/second² * (10 seconds)²

distance = 490 meters

Therefore, the parachutist will fall approximately 490 meters during 10 seconds of free fall.

The dependent variable of interest in examining whether the degree of parental involvement differs based on students' grade in school is the degree of parental involvement.

In this scenario, the independent variable is the students' grade in school (i.e., first, second, third, etc.). The dependent variable is the variable that is expected to be influenced by the independent variable. In this case, the dependent variable of interest is the degree of parental involvement.

The degree of parental involvement refers to the level or extent to which parents are engaged in their child's education and school-related activities. It can encompass various aspects, such as attending parent-teacher meetings, volunteering at school, helping with homework, and participating in school events.

By examining whether the degree of parental involvement differs based on students' grade in school, researchers or educators aim to explore any potential patterns or differences in parental involvement as children progress through different grade levels. This investigation can provide insights into how parental involvement may vary across grade levels and inform strategies to enhance parental engagement in education at specific stages of a child's schooling. Thus, the dependent variable of interest is the degree of parental involvement.

Some acceptable board lengths are: 15.8 ft, 16.20 ft and 16.10 feet

From the question, we have the following parameters that can be used in our computation:

Length = 16 ft

Percent error = 1.5%

This means that the acceptable lengths are

Acceptable = Length ± Percent error * Length

Substitute the known values in the above equation, so, we have the following representation

Acceptable = 16 ± 1.5% * 16

So, we have

Acceptable = 16 ± 0.24

Evaluate

Acceptable = 15.76 to 16.24

Some board lengths that should be accepted are 15.8 ft, 16.20 ft and 16.10 feet

In (a), we have

Acceptable = 15.76 to 16.24

Some board lengths that should be rejected are 14.8 ft, 17.20 ft and 12.10 feet

Here, we have

Lengths = 10, 12 and 14 feet

Length too long = 2.3 inches

Convert to inches

Length too long = 0.19

So, we have
