Answer:

mean: 87.5

median: 80

mode: 95

What is mean? : the sum of a collection of numbers divided by the number of numbers in the collection so for this is:

95+75+85+95= 350 divided by 4 because there's 4 numbers = 87.5 which is the mean

What is median?: The median is the value separating the higher half of a data sample so for this think of crossing each number at the opposite sides: 95 and 95 cancel now your left with 75 an 85 add them up and divide by 2 because there's 2 numbers **for median you are either left with 1 number or 2 if the case is 2 you ADD first then divide by 2 ALWAYS**: 75+85= 160/2= 80 for median

What is mode?: The mode is the value that appears most often in a set of data. So as we know 95 repeats the most

First u want to order the numbers from greatest to least 95,95,85,75
Mean: all numbers added up then divided by the number of numbers u have. So 95+95+85+75= 350 divided by 4 = 87.5
Mean=87.5
Median: the middle number. So after the numbers r ordered from greatest to least take one number off each side until u get to the middle. In this case there are two middle number 95 and 85 so u add them then divide by 2 95+85= 180 divided by 2= 90
Median= 90
Mode: the number that repeats most in the set of numbers. In this case the mode is 95 because there r 2 95s
Mode: 95

I need help with this homogeneous equation

slamgirl [31]

Answer:

$ln [1 - (\frac{y}{x} )^{2} ] + ln x + c = 0$ . This is the solution.

Step-by-step explanation:

The homogeneous differential equation is given by

$\frac{dy}{dx} = \frac{x^{2} + y^{2} }{2xy}$

⇒ $\frac{dy}{dx} = \frac{1 + (\frac{y}{x} )^{2} }{2(\frac{y}{x} )}$ ........ (1)

Now to solve this differential equation we assume that y = vx where v is another variable.

So, differentiating with respect to x we get $\frac{dy}{dx} = v + x \frac{dv}{dx}$

Therefore, the above equation (1) becomes

$v + x \frac{dv}{dx} = \frac{1 + v^{2} }{2v}$ {Since $v = \frac{y}{x}$ }

⇒ $x\frac{dv}{dx} = \frac{1 + v^{2} - 2v^{2} }{2v}$

⇒ $x\frac{dv}{dx} = \frac{1 - v^{2}}{2v}$

⇒ $\frac{2v}{1 - v^{2} } dv = \frac{dx}{x}$ {By separation of variables}

Now, integrating both sides we get,

$\int {\frac{2v}{ 1- v^{2}}} \, dv = \int {\frac{dx}{x} } \, dx$

⇒ $- \int {\frac{d(1 - v^{2} )}{1 - v^{2}}} = \int {\frac{dx}{x} }$

⇒ $- ln (1 - v^{2}) = ln x + c$ {Where c is the integration constant}

⇒ $ln [1 - (\frac{y}{x} )^{2} ] + ln x + c = 0$ (Answer)

HELP<br> ASAP<br> 35 POINTS

IgorLugansk [536]

By finding the distance between each pair of consecutive vertices, we could find that the perimeter is 26.8

<h3>How to find the perimeter of the figure?</h3>

To find the perimeter, we need to find the length of each side of the figure in the image.

And remember that the distance between two points (a, b) and (c, d) is:

√( (a - c)^2 + (b - d)^2 )

So we need to find the distance between each of the vertices of the figure.

The first two are (0, 3) and (4, -1). The distance between these is:

d = √( (0 - 4)^2 + (3 + 1)^2 ) = √25 = 5

The second pair is (4, -5) and (4, -1). The distance between these is:

d = √( (4 - 4)^2 + (-5 + 1)^2 ) = √16 = 4

The third pair is (4, -5) and (-5, 4). The distance between these is:

d = √( (4 + 5)^2 + (-5 - 4)^2 ) = √162 = 12.7

The last pair is (-5, 4) and (0, 3), this time the distance is:

d = √( (-5 - 0)^2 + (4 - 3)^2 ) = √26 = 5.1

The perimeter is the sum of these distances:

5 + 4 + 12.7 + 5.1 = 26.8

By finding the distance between each pair of consecutive vertices, we could find that the perimeter is 26.8

You invested $500 in a savings account at the end of the 6th grade. The account pays 4% annual

pogonyaev

Answer:

$632.66 is the amount of money in the savings account after graduation

Step-by-step explanation:

There are 12 grades in high school. So the number of years before graduation here is 6 years.

Now to know the amount of money, the equation to use is;

A(t) = a(1+r)^t

Here;

A(t) = ?

a = 500

r = 4% = 4/100 = 0.04

t = 6 years

Substituting these values into the equation, we have;

A(t) = 500(1 + 0.04)^6

A(t) = 500(1.04)^6

A(t) = $632.66
