How to solve -C(11c+ 4)

Answer:

4/25 i belive

Step-by-step explanation:

The proportion of the mortgage payments between $1100 and $2700 is (c) about 95%

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

Average = 1900

Standard deviation = 400

Payments are between $1100 and $2700

Calculate the z scores using:

Z = (X - Mean) / Standard deviation

So, we have

Z for $1100:

(1100 - 1900) / 400 = -2

Z for $2700:

(2700 - 1900) / 400 = 2

The proportion is then calculated as

P = (-2 < z < 2)

This gives

P = 0.9545

This means

P = approximately 95%

Answer:

3:25 pm

Step-by-step explanation:

The distance between New Orleans and Houston is : 353 miles

Departure time of the bus : 12:20 pm

Speed of the bus: 60 mph

After 45 minutes, the bus will be at a distance of : 45/60 * 60 = 45 miles

Distance remaining to cover = 353-45 = 308 miles

Speed of the motorcycle = 72 mph

Relative speed = 60 + 72 = 132 mph

Time the two will meet = 308 / 132 =  7/3 hrs

7/3 hrs = 2 hrs  20 minutes

Time the two will meet is ;

12:20 pm + 45 minutes + 2 hrs 20 minutes

= 3:25 pm

Both the bus and the motorcycle are driving opposite to each other.

From the given data, the time at which both the bus and the motorcycle will pass each other is 3:25 PM

The time at which both the motorcycle and the  bus will pass each other.

Let after t hour from the time when motorcycle starts, they both meet.

Then we have:

353 miles = 45 minute traveled by bus + distance traveled by bus in t hour + distance traveled by motorcycle in t time.

Since 45 minutes is three fourth of an hour, thus:

Distance traveled by bus in 45 minutes is calculated as:

\(D_{Bus}(45 \:\rm min) = 60 \times \dfrac{3}{4} \: \rm miles = 45 \: \rm miles\)

Distance traveled by bus in t hours is:

\(D_{Bus}(t \: \rm hours) = 60 \times t \: \rm miles = 60t \: \rm miles\)

Distance traveled by motorcycle in t hour is:

\(D_{motorcycle}(t \: \rm hours) = 72 \times t \: \rm miles = 72t \: \rm miles.\)

Thus, we have:

\(353 = 60t + 72t + 45\\\\308= 132t\\\\t = \dfrac{308}{132}\\\\t= \dfrac{7}{3}\: \rm hours\\\\t=2 \: \rm hours + 20 \: \rm minutes\)

Thus, time at which they meet was 12:20 PM + 45 minutes + 2 hours + 20 minutes = 3:25 PM

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

To find the equation of the parallel line we must first find the slope of the original line

That's

Slope of the through points

Hope this helps you

Answer:y=-1.583x-8.332

Step-by-step explanation:

First find slope from two points (-6-13)/(15+3)=-1.583

Now line is parallel so the slope would be same for the other line passing through (4,2) now as the general equation of line is

y=mx+c

It will take approximately 12 weeks to give away all of the prize money according to the given geometric progression

The series in question is a geometric series, meaning it can be defined by a formula.  find out how many weeks it will take to give away all of the prize money. a sweepstakes gives away $1,000,000 by giving away $25 in the first week, $75 in the second week, $225 in the third week, and so on. To find out how many weeks it will take to give away all of the prize money, sum up the series.

The formula for the sum of a geometric series is given by;

\(S_n=\frac{a(1-r^n)}{1-r}\)

where a is the first term
- r is the common ratio

- n is the number of terms

In this case, a = 25 and r = 3. find how many weeks it will take to give away all of the prize money, find n such that the sum of the series is equal to $1,000,000. Therefore, we have;

\(S_n=\frac{25(1-3^n)}{1-3}\)

\(S_n=-\frac{25(3^n-1)}{2}\)

\(1,000,000=-\frac{25(3^n-1)}{2}\)

\(-40,000=3^n-1\)

\(3^n=39,999\)

\(n=\log_3 39,999 \approx 11.38\)

(a) The covariance for X and Y i.e., Cov(X,Y) = -0.01

(b) rho for X and Y is -0.00038 (rounded to two decimal places).

To compute the covariance of X and Y, we have the following formula:

Cov(X,Y) = E[XY] - E[X]E[Y]

Where E[X] and E[Y] represent the expected values of X and Y respectively, while E[XY] represents the expected value of the product of X and Y.

Now to compute the covariance:

XY: 0(0.03) + 5(0.04) + 10(0.01) + 5(0.15) + 10(0.15) + 15(0.02) + 20(0.2) + 30(0.1) + 15(0.13) + 30(0.01) = 8.2E[X] = 0(0.03+0.06+0.02+0.1) + 5(0.04+0.15+0.2+0.1) + 10(0.01+0.15+0.13+0.01) = 7.3E[Y] = 0(0.03+0.04+0.01) + 5(0.06+0.15+0.15) + 10(0.02+0.2+0.13) + 15(0.02+0.1) = 10.1

So Cov(X,Y) = E[XY] - E[X]E[Y] = 8.2 - 7.3(10.1) = -0.01

Therefore, Cov(X,Y) = -0.01

To compute the correlation coefficient, we have the formula:

ρ = Cov(X,Y) / (σ_xσ_y)

Where Cov(X,Y) is the covariance, σ_x is the standard deviation of X, and σ_y is the standard deviation of Y.

To find σ_x:

σ_x = sqrt[0(0.03+0.06+0.02+0.1) + 5(0.04+0.15+0.2+0.1) + 10(0.01+0.15+0.13+0.01) - (7.3)^2]σ_x = 4.25

To find σ_y:

σ_y = sqrt[0(0.03+0.04+0.01) + 5(0.06+0.15+0.15) + 10(0.02+0.2+0.13) + 15(0.02+0.1) - (10.1)^2]

σ_y = 6.48

So ρ = Cov(X,Y) / (σ_xσ_y) = -0.01 / (4.25)(6.48) = -0.00038

Therefore, rho = -0.00038 (rounded to two decimal places).

(a) The sample size needed is 1,498 if the researcher uses the prior proportion of 0.669.

n = 1.497.87 or 1,498

(b)  The researcher should use a sample size of 1,692 if the proportion is unknown.

n = 1,691.06 or 1,692

When a researcher is designing a sampling study to measure a population parameter, like the proportion, the sample size must be determined. The key to calculating sample size is the margin of error the researcher desires. The smaller the margin of error, the larger the sample size needed.

(a) The sample size needed is 1,498 if the researcher uses the prior proportion of 0.669.

To find sample size for the proportion use the equation:

\(n=\frac{Z^2\pi (1-\pi )}{e^2}\)

Where:

Substituting values:

\(n=\frac{1.6449^2*0.50*0.331}{0.02^2}\)

n = 1.497.87 or 1,498

(b) The researcher should use a sample size of 1,692 if the proportion is unknown.

Use the same equation as in part (a). However, to maximize \(\pi (1-\pi )\) use 0.5 for \(\pi\).

Substituting the values:

\(n=\frac{1.6449^2*0.50*0.500}{0.02^2}\)

n = 1,691.06 or 1,692

Step-by-step explanation:

The scale of the drawing is 1:15

To determine the scale of the drawing, we need to find the ratio between the actual width of the yard and the width represented in the drawing.

Given that the actual width of the yard is 20 ft and it is represented as 16 in on the drawing, we need to convert the measurements to the same units before finding the ratio.

Since 1 ft is equal to 12 inches, the actual width of the yard in inches is:

20 ft * 12 in/ft = 240 in.

Now we can calculate the scale of the drawing by finding the ratio between the width in the drawing and the actual width:

Scale = Width on the drawing / Actual width

Scale = 16 in / 240 in

Simplifying the ratio:

Scale = 1/15

Therefore, the scale of the drawing is 1:15, which means that every inch on the drawing represents 15 inches in reality.

The pirate has gone into debt by $38,979 in base 10 due to his encounter with Captain Rusczyk.

To determine the amount of debt, we need to calculate the difference between the value of the goods the pirate stole and the amount demanded by Captain Rusczyk. The pirate initially stole $2345_6, which means it is in base 6. Converting this to base 10, we have $2\times6^3 + 3\times6^2 + 4\times6^1 + 5\times6^0 = 2\times216 + 3\times36 + 4\times6 + 5\times1 = 432 + 108 + 24 + 5 = 569$.

Captain Rusczyk demanded $41324_5, which means it is in base 5. Converting this to base 10, we have $4\times5^4 + 1\times5^3 + 3\times5^2 + 2\times5^1 + 4\times5^0 = 4\times625 + 1\times125 + 3\times25 + 2\times5 + 4\times1 = 2500 + 125 + 75 + 10 + 4 = 2714$.

Therefore, the pirate has gone into debt by $569 - 2714 = -2145$. Since the pirate owes money, we consider it as a negative value, so the pirate has gone into debt by $38,979 in base 10.
