Answer:

The median is 58

<h2>Step-by-step explanation:</h2>

To calculate the median, you must put the series of numbers in chronological order (smallest to biggest), then find the number in the middle. If there are two numbers, add them up and divide by two.

<h2>For this question:</h2>

<u>Step one; put them in order</u>

56 65 62 53 68 58 65 52 56

52 53 56 56 58 62 65 65 68

<u>Step two; find the middle</u>

52 53 56 56 58 62 65 65 68

<u>The answer</u>

Because there is an impair number, there is a number in the middle.

<em>58 is the median retirement age.</em>

A farmer has 500 acres to plant acres of corn, x, and acres of cotton, y. Corn costs $215 per acre to produce, and cotton costs

hodyreva [135]

Answer:

x + y = 500

215x + 615y = 187,500

Step-by-step explanation:

The first equation can show the amount of land. The farmer has 500 acres to plant corn, x, and cotton, y.

x + y = 500

The second equation can show the cost. The farmer has $187,500 to invest when corn costs $215 per acre and cotton costs $615 per acre.

215x + 615y = 187,500

The system of equations is

x + y = 500

215x + 615y = 187,500

aleksandr82 [10.1K]

Answer:

Given triangle ABC with altitude segment BD labeled x. Angles ADB and CDB are right angles by _____1._____, making triangle ABD and triangle BCD right triangles. Using the trigonometric ratios sine of A equals x over c and sine of C equals x over a. Multiplying to isolate x in both equations gives x = _____2._____ and x = a ⋅ sinC. We also know that x = x by the reflexive property. By the substitution property, _____3._____. Dividing each side of the equation by ac gives: sine of A over a equals sine of C over c.

stefan is three years younger than his sister katie. The sum of Stefans age three years ago and 2/3 of katies age at that time i

sammy [17]

If x is the age of S

And y is the age of K

So we have x=y+3

And the second equation is x-3 + 2/3)y = 12

We have to solve the system

x-y=3

x+2/3y=15

we find x=10.2 and y=7.2

<span>so Katie is 7 </span>
