Answer:13cm

Step-by-step explanation:

you will pay approximately $11,542 in interest over the life of the loan.

it will take approximately 82.3 months to pay off the loan.

To calculate the number of years, we divide the number of months by 12:

Years ≈ 82.3 / 12 ≈ 6.9 (rounded to one decimal place)

FV = P * [(1 + r)^n - 1] / r

Where:

FV = Future value of the annuity (total amount paid)

P = Monthly payment amount ($140)

r = Monthly interest rate (16% / 12 = 0.16 / 12 = 0.0133)

n = Number of periods (months)

We need to solve for n. Rearranging the formula, we have:

n = log((FV * r) / (P * r + P)) / log(1 + r)

Plugging in the given values:

FV = $3,400

P = $140

r = 0.0133

n = log(($3,400 * 0.0133) / ($140 * 0.0133 + $140)) / log(1 + 0.0133)

Calculating this expression:

n ≈ log(45.22) / log(1.0133)

Using a calculator, we find:

n ≈ 82.3

To calculate the number of years, we divide the number of months by 12:

Years ≈ 82.3 / 12 ≈ 6.9 (rounded to one decimal place)

So, it will take approximately 6.9 years to pay off the loan.

To calculate the total interest paid, we subtract the initial loan amount from the total amount paid:

Total interest = (P * n) - $3,400

Total interest = ($140 * 82.3) - $3,400

Total interest ≈ $11,542

Answer:

Cost of the food = $44.60

Step-by-step explanation:

Total cost of food, tax and tip = $55.75

Let

Cost of the food = x

Sales tax of 10% = 0.1x

Tip of 15% = 0.15x

Total cost = food + tax + tip

55.75 = x + 0.1x + 0.15x

55.75 = 1.25x

x =55.75/1.25

x = $44.60

Cost of the food = $44.60

The total interest you will earn in 30 years is approximately $241.61.

To calculate the total interest earned in 30 years, we need to use the formula for compound interest:
A = P(1 + r/n)^(nt) - P
Where:
A = the future value of the investment
P = the principal amount (initial deposit)
r = the annual interest rate (in decimal form)
n = the number of times the interest is compounded per year
t = the number of years
In this case, the principal amount is $200, the annual interest rate is 3% (or 0.03 as a decimal), the interest is compounded monthly (so n = 12), and the time period is 30 years (so t = 30).
Plugging in these values into the formula:
A = 200(1 + 0.03/12)^(12*30) - 200
Now we can simplify and calculate:
A = 200(1.0025)^(360) - 200
A = 200(2.208040033) - 200
A ≈ 441.6080066 - 200
A ≈ 241.6080066

A typical rectangle is shown below. The value of x corresponding to the lower end of the rectangle is x = −y1/2 and the value of x corresponding to the upper end of the rectangle is x = 1. So the height of the rectangle is x2 and the width is Δy = 1/n. Therefore, the area of the rectangle isSince the rectangle is located below the curve, this approximation underestimates the true area of the region.

 Therefore, the area of the rectangle is Since the rectangle is located above the curve, this approximation overestimates the true area of the region.

The Laplace transform of a cos(ωt) b sin(ωt) is [(a + ib)s]/[(s^2) + ω^2].

We can use the identity cos(a)sin(b) = (1/2)(sin(a+b) - sin(a-b)) to write:

a cos(ωt) b sin(ωt) = (a/2)(e^(iωt) + e^(-iωt)) + (b/2i)(e^(iωt) - e^(-iωt))

Taking the Laplace transform of both sides, we get:

L{a cos(ωt) b sin(ωt)} = (a/2)L{e^(iωt)} + (a/2)L{e^(-iωt)} + (b/2i)L{e^(iωt)} - (b/2i)L{e^(-iωt)}

Using the fact that L{e^(at)} = 1/(s-a), we can evaluate each term:

L{a cos(ωt) b sin(ωt)} = (a/2)((1)/(s-iω)) + (a/2)((1)/(s+iω)) + (b/2i)((1)/(s-iω)) - (b/2i)((1)/(s+iω))

Combining like terms, we get:

L{a cos(ωt) b sin(ωt)} = [(a + ib)/(2i)][(1)/(s-iω)] + [(a - ib)/(2i)][(1)/(s+iω)]

Simplifying the expression, we obtain:

L{a cos(ωt) b sin(ωt)} = [(a + ib)s]/[(s^2) + ω^2]

Answer:100

Step-by-step explanation:

The question confuses you since there is no extra variable to help you which is you have to create it yourself.

Let's create a variable called 'y' and make it the empty angle inside the triangle and next to x + 30. Since at K it will always equal to 180° because x+30 + y = 180°, we can rearrange to make y alone which would be become:

\(y=-x-30+180\) which then becomes \(y = -x+150\).

Also since the inside sum of angles in a traingle is equal to 180°, this can be written as

\(180 = (x-40) +(x-30)+y\)

if we replace y with the equation we get

\(180=(x-40)+(x-30) + (-x+150)\)

which can be simplified to

\(180=x+80\) because 2x-x = x and -70+150 = 80

If we rearrange to solve for x, we get:

\(x = 180-80\) ⇒ \(x=100\)

We can verify this by putting the value of x in both equation:

\(y = -100+150 = 50\) angle at k

\(100-40=60\) angle at j

\(100-30=70\) angle at l

\(50+60+70=180\) this match the rules of the sum of interior angle always equal 180°

Answer:

Follow the lines

Step-by-step explanation:

Follow what the lines go with what the table has.

To make this really easy, find the slope of the line

To do this you find an easy point.

Ex. x=3 and y= 150

then take it into a slope y-intersept formula

y= mx

150= 3x

50 = x

so for every time x goes up one interval, y increases at a rate of 50.

And for y, do the opposite, for every 50 y, x goes up 1.

By following this linear path, you should really beable to solve the graph on the right. (If you need to, use a calculator for dividing the y numbers by 50 to get x)

The resulting index value represents the position of the desired element in a hypothetical one-dimensional array formed by collapsing all the dimensions of the original multidimensional array into a single dimension.

The equivalent single-dimensional index for accessing the element ar[29][1][3][0][17][20] in the array int ar[45][14][10][10][43][50] can be calculated as follows:

First, we need to determine the number of elements before the desired element in each dimension. Starting from the outermost dimension:

The size of the first dimension is 45, so there are 45 elements in each block of size 14x10x10x43x50.

The size of the second dimension is 14, so there are 14 elements in each block of size 10x10x43x50.

The size of the third dimension is 10, so there are 10 elements in each block of size 10x43x50.

The size of the fourth dimension is 10, so there are 10 elements in each block of size 43x50.

The size of the fifth dimension is 43, so there are 43 elements in each block of size 50.

The size of the sixth dimension is 50.

To calculate the equivalent single-dimensional index, we multiply the number of elements in each dimension by the respective size of the block and sum them all together. In this case, it would be:

Index = (29 * (14 * 10 * 10 * 43 * 50)) + (1 * (10 * 10 * 43 * 50)) + (3 * (10 * 43 * 50)) + (0 * (43 * 50)) + (17 * 50) + 20

While we looking into the given question, we know te following values,

Principal amount = $6000

Time period = 16 may 2010 to 9 October 2010

The number of days between 16 may 2010 to 9 October 2010 is

=> 146 days.

Here we have the interest for 1 year,

So, the time period is written as,

And the interest rate = 10%

Here we have to convert R percent to r a decimal

r = R/100 = 10%/100 = 0.1 per year.

Now, we have to apply the values on the formula, then we get by solving our equation:

A = 6000(1 + (0.1 × 0.4)) = 6240

A = $6,240.00

I) The requested probabilities are as follows:

P(X ∈ (0, 1)) cannot be calculated without additional information.

P(Y ∈ (3, 14)) and P(T ∈ (0, 1)) require using the respective cumulative distribution functions (CDFs) for the chi-squared and t-distributions.

P(F ∈ (0, 1)) requires using the cumulative distribution function (CDF) for the F-distribution.

II) For α = 0.05, the significance level or Type I error rate, the critical values and test statistics are not provided as the specific hypothesis tests or confidence intervals are not mentioned.

I) To calculate the probabilities, we can use the probability density functions (PDFs) of the respective distributions.

a) For X ~ N(-1, 9), where X follows a normal distribution with mean -1 and variance 9, we need to find P(X ∈ (0, 1)).

We can standardize X by subtracting the mean and dividing by the standard deviation:

Z = (X - μ) / σ = (X - (-1)) / √9 = (X + 1) / 3

Then, using the standard normal distribution table or a calculator, we can find the probability:

P(X ∈ (0, 1)) = P(Z ∈ ((0 + 1)/3, (1 + 1)/3)) = P(Z ∈ (1/3, 2/3))

b) For Y ~ χ^2(12), where Y follows a chi-squared distribution with 12 degrees of freedom, we need to find P(Y ∈ (3, 14)).

This probability involves the cumulative distribution function (CDF) of the chi-squared distribution.

P(Y ∈ (3, 14)) = P(Y < 14) - P(Y < 3) = CDF(14) - CDF(3)

c) For T ~ t(10), where T follows a t-distribution with 10 degrees of freedom, we need to find P(T ∈ (0, 1)).

This probability also involves the CDF of the t-distribution.

P(T ∈ (0, 1)) = CDF(1) - CDF(0)

d) For F ~ F(8, 9), where F follows an F-distribution with 8 and 9 degrees of freedom, we need to find P(F ∈ (0, 1)).

This probability also involves the CDF of the F-distribution.

P(F ∈ (0, 1)) = CDF(1) - CDF(0)

II) For α = 0.05, which represents the significance level or Type I error rate, we can use the respective inverse CDFs (quantile functions) to find the critical values for each distribution.

The critical values define the boundaries of the rejection region in hypothesis testing or confidence intervals.

For example, for the normal distribution N(-1, 9), we can find the critical values z1 and z2 such that P(Z < z1) = α/2 and P(Z > z2) = α/2, where Z follows a standard normal distribution.

Then, the interval (-∞, z1) ∪ (z2, +∞) represents the rejection region for the null hypothesis.

Similarly, we can find the critical values for the other distributions: chi-squared, t-distribution, and F-distribution, using their respective inverse CDFs.

It's important to consult statistical software or statistical tables to obtain the precise critical values corresponding to a specific α level for each distribution.

Remember, these calculations and critical values are used in statistical inference to make decisions based on observed data, and the specific use case and hypothesis testing context should be considered for accurate interpretation.

The hourly wage of the person is $10, while their coworker earns 10% more, making it $11 per hour.
Let's denote the person's hourly wage as x. According to the given information, the coworker earns 10% more than the person. This means the coworker's hourly wage is x + 0.10x = 1.10x.
Together, they make $16 per hour, so their combined wages are x + 1.10x = 2.10x. Since this equals $16, we can solve for x: 2.10x = $16, which gives x = $7.62.
After taking Math 1010, the person's hourly wage increases to $12. The raise amount can be calculated as the difference between the new wage and the previous wage, which is $12 - $7.62 = $4.38. To calculate the raise percentage, we divide the raise amount by the previous wage and multiply by 100: (4.38 / 7.62) * 100 ≈ 57.4%. Therefore, the raise is approximately 57.4%.

The probability that five of the eight students exhibit an higher IQ than the median of the general population is 0.21875

Step-by-step explanation:

The given parameters are;

The number of students in the sample, n = 8

The number of the students, x, that exhibit higher IQ's than the median = 5

The probability of obtaining the given result by chance is given as follows;

P(x) = n!/((n - x)!x!) × pˣ × qⁿ⁻ˣ

The probability that a student exhibit higher IQ's than the median = 0.5 = p

Similarly, we have, the probability that a student exhibit lower IQ's than the median = 0.5 = q

Substituting the known values, gives;

P(5) = (8!/((8 - 5)!×5!)) × 0.5^(5) × 0.5^(8 - 5) = 0.21875

Therefor, the probability that 5 of the 8 students exhibit an higher IQ than the median of the general population, P(5) = 0.21875.

\(Pattern: 2187, 729, 243, 81, 27, 9,3, 1\)

\((b)\)

\(Pattern = 972,324,108,36\)

Step-by-step explanation:

Given [Missing from the question]

\(Pattern: 2187, 729, 243, 81\)

Solving (a): Continue the pattern using the divide by 3 rule

To do this, we simply divide the last term by 3, to get the next term.

So, we have:

\(81/3 = 27\)

\(27/3 = 9\)

\(9/3 = 3\)

\(3/3 = 1\)

So, the pattern is:

\(Pattern: 2187, 729, 243, 81, 27, 9,3, 1\)

Solving (b): 4 terms of a different pattern using the same rule.

Let the first term be: 972

So, the next three terms is:

\(972/3 =324\)

\(324/3 = 108\)

\(108/3 =36\)

So, the pattern is:

\(Pattern = 972,324,108,36\)

The actual distance between the two cities is 280 miles.

A map's key shows that every of 5 inches on the map represents 200 miles of actual distance. Suppose the distance between two cities on the map is 7 inches. What is the actual distance between the two cities? Write the rule you used to find the actual distance.

The rule used to find the actual distance between the two cities is multiplying the scale factor by the distance on the map.

The scale factor is given as 200 miles for every 5 inches, which means that for every 1 inch on the map, the actual distance is 40 miles. Hence, the actual distance for 7 inches on the map is calculated as follows:

Actual distance = Scale factor × Distance on the map Scale factor = 200 miles / 5 inches = 40 miles per inch distance on the map = 7 inches Actual distance = 40 miles per inch × 7 inches Actual distance = 280 miles

Answer:

The lower left one.

Step-by-step explanation:

If you expand and rearrange it, you will find out both of its constant cancel out, and leave you with 3w=3w. So w have infinite number of solutions.

Answer:

\(6(\frac{1}{2} w-1)=3(w-2)\)

Step-by-step explanation:

\(6(\frac{1}{2} w-1)=3(w-2)\)              (Isolate parentheses)

\(3w-6=3w-6\)                      (Add six to both sides to isolate one variable w)

\(3w=3w\)                                  (Divide by three to isolate variable w)

\(w=w\)

Because we got \(w=w\), that means that any number you put in for w will still get you the same answer, or "infinite answers." If you try, say 5, you would still get the same answer if you put in 9. It has infinite answers.

I hope this helped :)
