on average the number of electric guitars sold in texas each year is $91,399, which is seven times the average number of guitars sold each year in Wyoming. How manu electric guitars, on average, are sold each year in Wyoming?

Answers

The average electric guitars sold each year in Wyoming is 13,057.

What is Multiplication?

Multiplication of two numbers is defined as the addition of one of the number repeatedly until the times of the other number.

a × b means that a is added to itself b times or b is added to itself a times.

Given that,

on average the number of electric guitars sold in Texas each year is $91,399, which is seven times the average number of guitars sold each year in Wyoming.

Average number of guitars sold each year in Texas = 91,399

This number is seven times the average number of guitars sold each year in Wyoming.

Let x be the average number of guitars sold in Wyoming each year.

7x = 91,399

Dividing both sides of the equation by 7,

x = 91399 / 7

x = 13,057

Hence 13,057 electric guitars are sold each year in Wyoming.

Dy/dx=2xy/x²+y² solve

Answers

Answer:

$y=(-1)/(2) \sqrt[]{4x^2+4c_(1)^2} -c_(1)\ or \ (1)/(2) \sqrt[]{4x^2+4c_(1)^2} -c_(1)$

Step-by-step explanation:

As it is first order nonlinear ordinary differential equation

Let y(x) = x v(x)

2xy/(x²+y²)=2v/(v^2+1)

dy=xdv+vdx

dy/dx=d(dv/dx)+v

x(dv/dx)+v=(2v)/(v^2+1)

dv/dx=[(2v)/(v^2+1)-v]/x

$(dv)/(dx)=(-(v^2-1)v)/(x(v^2+1))$

$(v^2+1)/((v^2-1)v)dv=(-1)/(x)dx$

∫ $(v^2+1)/((v^2-1)v)dv$ = ∫ $(-1)/(x)dx$

u=v^2

du=2vdv

Left hand side:

∫ $(v^2+1)/(v(v^2-1))dv$

=∫ $(u+1)/(2u(u-1))du$

= $(1)/(2)$ ∫ $((2)/(u-1) -(1)/(u) )du$

= $ln(u-1)-(ln(u))/(2) +c$

= $ln(v^2-1)-(ln(v^2))/(2)+c$

Right hand side:

$=-ln(x)$

Solve for v:

$v=-\frac{-c_(1)+\sqrt{c_(2)+4x^2 } }{2x} \ or \ \frac{-c_(1)+\sqrt{c_(2)+4x^2 } }{2x}\n$

$y=(-1)/(2) \sqrt[]{4x^2+4c_(1)^2} -c_(1)\ or \ (1)/(2) \sqrt[]{4x^2+4c_(1)^2} -c_(1)$

Graph the line with slope 1/2 passing through the poin

Answers

Answer:

See explanation below.

Step-by-step explanation:

To make use of the tools they give you, start at the point (-5, -2) which you know is a point the line goes through, then draw a line that goes towards the right following the rule given by the slope "1/2" (rise/run) which means that every 2 units to the right, you go one unit up. so from the point -5 in x, you go to the point -3 in x, and from -2 in y you move up one unit to -1

Therefore the line joins (-5, -2) to the point (-3, -1)

One question in the survey asked how much time per year the children spent in volunteer activities. The sample mean was 14.76 hours and the sample standard deviation was 16.54 hours.Required:a. Based on the reported sample mean and sample standard deviation, explain why it is not reasonable to think that the distribution of volunteer times for the population of South Korean middle school students is approximately normal. b. The sample size was not given in the paper, but the sample size was described as large. Suppose that the sample size was 500. Explain why it is reasonable to use a one-sample t confidence interval to estimate the population mean even though the population distribution is not approximately normal. c. Calculate and interpret a confidence interval for the mean number of hours spent in volunteer activities per year for South Korean middle school children.
