Then, the first statement XA ≡ XY is false
VashaNatasha [74]3 years ago
3 0

Answer:

Statement 1. XA ≡ XY is incorrect.

Step-by-step explanation:

When we use the compass to construct two equidistant points from a point P then we get points X and Y.

In other words XP ≡ PY

Similarly, when we mark arcs from point X and point Y with a fixed length, we get a point of intersection of arcs at point A.

This point A will be equidistant from points X and Y.

Therefore, XA ≡ XY

But in any condition length PX will not be equal to PY.

Now we are sure that option 1. XA ≡ XY will not be correct.

Therefore, Option 1. XA ≡ XY is incorrect.

The base of a solid right pyramid is a regular hexagon with a radius of 2x units and an apothem of units. A solid right pyramid
Xelga [282]

Answer:

6 x^2*\sqrt{3}

Step-by-step explanation:

The base of the pyramid we need to study is a hexagon.

Let's look at the attached image of an hexagon to understand how we are going to find the area of this figure.

Notice that an hexagon is the combination of 6 exactly equal equilateral triangles in our case of size "2x" (notice that the "radius" of the hexagon is given as "2x")

Therefore the area of the hexagon is going to be 6 times the area of one of those equilateral triangles.

We know the area of a triangle is the product of its base times its height, divided by 2: \frac{base*height}{2} = \frac{2x*height}{2}

We notice that the triangle's height is exactly what is called the "apothem" of the hexagon (depicted in green in our figure) which measures x\sqrt{3}, so replacing this value in the formula above for the area of one of the triangles:

\frac{2x*height}{2}= \frac{2x*x\sqrt{3} }{2}=x^2\sqrt{3}

Then we multiply this area times 6 to get the total area of the hexagon (6 of these triangles):

Area of hexagon = 6x^2\sqrt{3}

which is the last option given in the list.

aleksley [76]

Answer:

556

Step-by-step explanation:

Find out how much 1.4% is of 500 which is 7

so 7 x 8 = 56

now we add it 500 + 56 = 56

Let (X1, X2, X3, X4) be Multinomial(n, 4, 1/6, 1/3, 1/8, 3/8). Derive the joint mass function of the pair (X3, X4). You should b
Ket [755]

Answer:

The random variables in this case are discrete since they have a Multinomial distribution.

The probability mass function for a discrete random variable X is given by:

P(X=x_{i}  )

Where are x_{i} are possible values of X.

The joint probability mass function of two discrete random variables X and Y is defined as

P(x,y) =P(X=x,Y=y).

It follows that, The joint probability mass function of X_{3}   , X_{4} is :

P(X_{3}, X_{4} ) = P( X_{3} = x_{3}, X_{4} = x_{4} ) =\frac{1}{8} +\frac{3}{8} =\frac{1}{2}

What is the volume of the cone with radius 4 ft and height 10 ft? Round to the nearest cubic foot.
Anit [1.1K]

Answer:

  D)  168 ft^3

Step-by-step explanation:

The volume of a cone is given by the formula ...

  V = (1/3)πr^2·h

Putting your numbers in, we have ...

  V = (1/3)π(4 ft)^2·(10 ft) = (160π/3) ft^3 ≈ 168 ft^3
