Answer:

It will take about 13.5 years for the money to grow to $5,500
That would be about 13 years and 6 months

Step-by-step explanation:

The formula for accrued amount(principal + interest) is given by:
\(A = P\left(1 + \dfrac{r}{n}\right)^{nt}\quad(1)\\\)

where
P = Principal amount
r = R/100 where R is the annual interest rate as a percentage
n= number of times compounded per year
t = number of years

Given

A = $5,600
P = $3,500
R = 3.35% ==> r = 3.35/100 = 0.0335
n = 12 (since there are 12 months in a year)

We have to find out t

Plugging known values into equation (1)

\(5500 = 3500\left(1+ \dfrac{0.0335}{12}\right)^{12t}\\\\5500 = 3500 \left(1+ 0.002791\right)^{12t}\\\\5500 = 3500 (1.002791)^{12t}\)

Switch sides so unknown appears on the left side:
\(3500 (1.002791)^{12t} = 5500\)

Divide by 3500 both sides:
\((1.002791)^{12t} = \dfrac{5500 }{3500}\\\\(1.002791)^{12t} = 1.5714\\\\\)

Take logs on both sides:
\(\ln \left(1.002791^{12t}\right)=\ln \left(1.5714\right)\\\\\)

We have
\(\ln \left(1.002791^{12t}\right) = 12t\ln \left(1.002791\right)\\\\\)

Therefore we get
\(12t\ln \left(1.002791\right)=\ln \left(1.5714\right)\\\\t\ln \left(1.002791\right)=\ln \left(1.5714\right)\\\\\\\)

Dividing both sides by \(12\ln \left(1.002791\right)\) this works out to
\(t=\dfrac{\ln \left(1.5714\right)}{12\ln \left(1.002791\right)}\)

\(t = 13.51359\; years\)

Rounding to one decimal place
\(t = 13.51\; years\\\)

This would be roughly 13 years and 6 months

As y varies inversely as x, the value of y when x = 3 is 45.

Inverse proportionality is expressed as:

y ∝ 1/x

Hence:

y = k/x

Where k is the constant of proportionality.

First, we determine the constant of proportionality.

Using the information given in the problem.

When x = 5, y = 27

Substituting these values into the formula, we get:

y = k/x

27 = k/5

k = 135

Now that we have found the value of k, we can use the formula to find y when x = 3. Substituting x = 3 and k = 135, we get:

y = k/x

y = 135/3

y = 45

Therefore, the value of y is 45.

Answer:

........ true ...

obviously -3 is greater than -4

Answer:

False.

Step-by-step explanation:

There are many real numbers between -4 and -3. For example -3.5.

(a) x has a mean of x and a variation of x that is also x. In a similar way, the variance and mean of y are both y.

Let's denote λx and λy as the arrival rates for the morning and afternoon hours, respectively.

Given that x and y are Poisson distributed, we know that the mean and variance of a Poisson random variable are both equal to its rate parameter. Therefore, the mean of x is λx, and the variance of x is also λx. Similarly, the mean of y is λy, and the variance of y is λy.

(b) The equation y = x + 8 indicates that the mean of y, y, is 8 greater than the mean of x, x.

The first moment of x is less than the first moment of y by 8, which can be expressed as:

λx < λy

This implies that the mean of y, λy, is 8 more than the mean of x, λx:

λy = λx + 8

(c) Variance of y will be : 0.4 * λy^2 + 16λy - 64 = 0.

The second moment of x is 60% of the second moment of y, which can be expressed as:

λx^2 = 0.6 * λy^2

We have three equations:

1. λy = λx + 8

2. λx = λy - 8

3. λx^2 = 0.6 * λy^2

Solving these equations simultaneously, we can find the values of λx and λy.

From equation (2):

(λy - 8)^2 = 0.6 * λy^2

Expanding and simplifying the equation:

λy^2 - 16λy + 64 = 0.6 * λy^2

Rearranging and simplifying further:

0.4 * λy^2 + 16λy - 64 = 0

We can solve this quadratic equation to find the value of λy. Once we have λy, we can directly calculate the variance of y as λy.

Answer:

Option A: 0.07c = 1.26 is the correct answer

Step-by-step explanation:

Given that the price of shirt is denoted by c.

Given that the sales tax is 0.07 times of the cost of shirt.

Mathematically it can be written as:

\(Sales\ tax=0.07c\)

Now it is also given in the statement that the sales tax is $1.26

Putting this value in the above equation

\(1.26 = 0.07c\)

As we have to find the cost, dividing both sides by 0.07

\(\frac{1.26}{0.07} = \frac{0.07x}{0.07}\\c = \frac{1.26}{0.07}\)

Hence, we saw that the intermediate equation was: 1.26 = 0.07c

So,

Option A: 0.07c = 1.26 is the correct answer

Answer: A. 0.07 · c = 1.26

Step-by-step explanation:

Sales tax (0.07) x cost (c) = price (1.26)

Based on the given CDI and BDI values, investing in Segment 2 would be more advantageous for the brand.

Brand X's growth can be determined by analysing  CDI (Category Development Index) and BDI (Brand Development Index) in two segments, Segment 1 and Segment 2.

Segment 1 has a CDI of 125 and a BDI of 95, while Segment 2 has a CDI of 85 and a BDI of 110. Based on the CDI and BDI values, Segment 2 appears to be a more favourable investment opportunity for the brand because the BDI is higher than the CDI.

CDI is an index that compares the percentage of a company's sales in a specific market area to the percentage of the country's population in the same market area. It provides insights into the market penetration of the brand in relation to the overall population.

BDI, on the other hand, compares the percentage of a company's sales in a given market area to the percentage of the product category's sales in that same market area. It indicates the brand's performance relative to the product category within a specific market.

A higher BDI suggests that the product category is performing well in the market area, indicating a higher growth potential for the brand. Conversely, a higher CDI indicates that the brand already has a strong presence in the market area, implying limited room for further growth.

Therefore, The higher BDI suggests a stronger potential for growth in this market compared to Segment 1, where the CDI is higher than the BDI. By focusing on Segment 2, the brand can tap into the market's growth potential and expand its market share effectively.

The values of x in the given equation, (x-7)^2=36, are x = 13 and x = 1. The correct options are the first and second options - x = 13 and x = 1

From the question, we are to determine the values of x in the given equation. The given equation is:

(x-7)^2=36

To solve the equation (x-7)^2=36, we can take the square root of both sides and solve for x:

(x-7)^2 = 36

Taking the square root of both sides:

x - 7 = ±6

Adding 7 to both sides:

x = 7 ± 6

So we get two possible values of x:

x = 7 + 6 or x = 7 - 6

x = 13 or x = 1

Hence, the correct values of x are:

x = 13

If a change in a certain population is expressed then there is no specific population value at which the highest rate of growth occurs based on the given differential equation.

A differential equation is a mathematical equation that relates an unknown function to its derivatives. It involves one or more derivatives of the unknown function with respect to one or more independent variables.

a) The population increases when 0 < P < 5600.

b) The population decreases when P < 0 or P > 5600.

c) To find the population at the highest rate of growth, we need to find the maximum of the function dP/dt = 0.8P(1 - P/5600). Setting the derivative equal to zero, we have 0.8 - 0.8P/5600 + 0.8P/5600 = 0. Simplifying further, we find 0.8 = 0, which has no solutions.

Hence, there is no specific population value at which the highest rate of growth occurs based on the given differential equation.

The scatter plot in the instance demonstrates a negative association.

The values for two different numerical variables are represented by dots in a scatter plot (also known as a scatter chart or scatter graph).

Each dot's location on the horizontal and vertical axes represents a data point's values.

To view relationships between variables, utilize scatter plots.

So, we say there is a positive correlation between the variables when the y variable tends to rise when the x variable rises.

We say there is a negative correlation between the variables when the y variable tends to decline as the x variable rises.

The scatter plot's points appear to form a line that runs downward from left to right.

It follows that the relationship between the x- and y-coordinates is inverse.

Therefore, the scatter plot in the instance demonstrates a negative association.

Explanation:  

32 marbles in total.

18 red marbles

4 blue marbles

10 green marbles.

You are asked what part of Osteen's marbles are red?

Probability = number of possible outcomes/total number of out outcomes.

P(Red) = 18/32 = 9/16

Both, 18 and 32 are divisible by 2 which gives 9/16. Since 9/16 cannot be reduced any further, we live it as it is. If you wanted to plug this into a calculator that would give 0.5625 which is 56.25% of Osteen's marbles are red.

P(Blue) = 4/32 = 1/8. 1/8 = 0.125 which 12.5% of his marbles are blue.

P(Green) = 10/32 = 5/16. 5/16= 0.3125 which 31.25 of his marbles are green. When you add 0.5625 + 0.125 + 0.3125 = 1 which is 100%. All probabilities add up to 1.

Dyscalculia is a learning disorder that affects a person’s ability to do the math.

A learning problem called dyscalculia diminishes a person's capacity for math. Similar to how dyslexia impairs reading-related brain regions, dyscalculia interferes with the knowledge and skills connected to math and numbers. Although dyscalculia often first manifests in childhood, it can even affect adults who are unaware of it.

The signs of this condition typically emerge in childhood, particularly as kids start to master the fundamentals of math. However, many adults who suffer from dyscalculia are unaware of it. When forced to do the math, people with dyscalculia frequently experience mental health problems like anxiety, depression, and other distressing emotions.
