Answer:

BxA=F

Step-by-step explanation:

Diagonal AC must be 20 feet so that ∠B will be 90°.

According to asked question, buck is creating a horse coral  by designing in such a way that corners will be at 90°.

So according to question we have to make ∠B as 90°.

So quadrilateral ABCD becomes a rectangular.

Therefore ΔABC  will be a right-angle triangle in which we can use Pythagoras theorem to measure the diagonal AC.

The Pythagoras Theorem says that in a right-angle triangle, the square of the hypotenuse is the sum of square of the other two sides of the right-angle triangle.

In the right-angle tringle ΔABC,

AC²=AB²+BC²

⇒ AC²=16²+12²

⇒ AC²=256+144=400

⇒AC=√400

⇒AC=20 feet

Therefore, Diagonal AC must be 20 feet so that ∠B will be 90°.

Step-by-step explanation:

If you want to calculate the perimeter of an irregular trapezoid, there's no special formula - just add all four sides:

Trapezoid perimeter = a + b + c + d

Maybe you've noticed, but it's the formula for any quadrilateral perimeter.

There's also an option that that presents itself with certain special trapezoids - like an isosceles trapezoid, where you need a, b, and c sides. Another example is a right trapezoid, where the length of the bases and one leg are enough to find the shape's perimeter (the last leg is calculated using Pythagoras' Theorem).

The internal angle sum of a quadrilateral is :

where n represents number of sides.

In a quadrilateral there are four sides,

The temperature above and below the freezing points are 5°C and –10°C respectively. The correct option is B.

The temperature at which a liquid begins to solidify Melting point is the temperature at which the liquid and solid states of a substance are in equilibrium at atmospheric pressure. Water has a freezing point of 0° Celsius or 32° Fahrenheit.

The freezing point of the water is 0 degrees Celcius. It means that below 0 degrees like in negative temperature water becomes ice. Above 0 degrees Celcius the water remains in a liquid form.

Therefore, the temperature above and below the freezing points are 5°C and –10°C respectively. The correct option is B.

Probability is the chance of an event to occur from a total number of outcomes.

The formula for probability is given as:

Probability = Number of required events / Total number of outcomes.

The probability of Nancy picking a purple marble is 1/12

Option A is the correct answer.

It is the chance of an event to occur from a total number of outcomes.

The formula for probability is given as:

Probability = Number of required events / Total number of outcomes.

We have,

There are three different colors- blue, red, and purple.

The probability of choosing a blue marble is 0.25

The probability of picking a red marble is 2/3

The total probability of always 1.

The probability of Nancy picking a purple marble.

= 1 - (0.25 + 2/3)

= 1 - (1/4 + 2/3)

= 1 - (3 + 8)/12

= 1 - 11/12

= 1/12

Thus,

The probability of Nancy picking a purple marble is 1/12

Option A is the correct answer.

The difference between the mean and median is that the mean is the average number. f.e: 1, 2, 2, 2, 3, 3, 4, 5 - and if you add all those up, the mean would be 3, or 2.

But the median is the number in the middle Number.

What if you have 2 medians, though?

Well, that’s easy to solve IMO.

F.e: 22, 22, 23, 23, 23, 24, 24, 24, 25, 25

The median is either 23 or 24, right?

Okay. That’s simple. But what exactly do we do?

Let me show you:

So get the sum of 23 and 24, which is 47.

Now divide 47 by 2. And what do we get?

23.5.

Now round that, and you get 24. So 24 is the median!

Hope that helps!

Answer:

mean is the AVERAGE of all numbers

Step-by-step explanation:

because when  you  add up all the numbers then you divide it by the TOTAL NUMBER of NUMBERS!

and a median is the middle number in a sorted, ascending or descending, list of numbers and can be more descriptive of that data set than the average.

Answer: The numbers in order are 13, 21, 36

Step-by-step explanation:

First of all, we must convert all the information given in the question into equations so we can look it from a simplified angle, and hence, solve it.

So, let's start off by giving each of the unknown numbers a name. Let's call the first number a, the second number b, and the third number c.

Therefore:

"The second of three numbers is 8 more than the first" gives us:

b = 8 + a

"... the third is 3 less than 3 times the first" gives us:

c = 3a - 3

and "the third number is 15 more than the second" gives us:

c = 15 + b

Now, we can substitute b = 8 + a into c = 15 + b, to get:

c = 15 + (8 + a), which simplified gives us:

c = 23 + a

With that done we can use elimination.

We've got c = 23 + a, and c = 3a - 3. We want to eliminate 'a', so we should multiply both sides of c = 23 + a by (-3) to get: -3c = -69 - 3a.

Now we can eliminate the 'a' variable:

c = 3a - 3

-3c = -3a - 69

-------------

-2c = -72

Therefore, we can solve for 'c' by dividing both sides by -2, which leaves us with:

c = 36

Now we can plug that value of 'c' into the equation c = 15 + b, to solve for b:

36 = 15 + b (Subtract 15 from both sides)

21 = b

Now that we've got a value for 'b', we can plug it into the equation b = 8 + a to solve for 'a':

21 = 8 + a (Subtract 8 from both sides)

13 = a

Sorry it's very long, but it's how I solved this

Hope this helped! ;)
