Polygon Y has an area of 11 square units. Celia drew a scaled version of polygon Y using a scale factor of 3 and labeled it poly
Ivahew [28]

Answer:

99 square units

Step-by-step explanation:

We are given;

  • a polygon Y whose area is 11 square units
  • The scale factor which it was drawn to become polygon Z is 3

We are required to determine the area of polygon Z

We need to know that;

Area scale factor = Square of Linear scale factor

That is;

Area scale factor = 3²

       = 9

Hence;

Area of polygon Z = Area of polygon Y × Area scale factor

                              =  11 square units × 9

                             = 99 square units

Thus, the area of polygon Z is 99 square units

Find the area of the shape shown below using the screenshot I took
yarga [219]

For this case we have that the figure shown is composed of three triangles and a square. By definition, the area of a triangle is given by:

A = \frac {1} {2} b * h

Where:

b: It's the base

h: It's the height

We have 3 triangles, then the sum of their areas will be:

A = \frac {1} {2} (9 * 3.5) + \frac {1} {2} (2 * 2) + \frac {1} {2} (5 * 2)\\A = 15.75 + 2 + 5\\A = 22.75 \ units ^ 2

On the other hand, the area of a square is given by:

A = l ^ 2

Where:

l: It's the side of the square

According to the figure we have:

A = 2 ^ 2\\A = 4 \ units ^ 2

So, the total area is:

A_ {t} = 22.75 + 4\\A_ {t} = 26.75 \ units ^ 2

Answer:

A_ {t} = 26.75 \ units ^ 2

Let the experiment be the toss of six coins in a row. Let X be number of of coins that turn up heads. Determine whether the foll
Leni [432]

Answer:

True

Step-by-step explanation:

When a coin is tossed six coins in a row, there are a total of 2^6 outcomes.

The possible number of times for a heads are {0, 1, 2, 3, 4, 5, 6}.

Let our random variable, Number of coins that turn up heads be X

X={0, 1, 2, 3, 4, 5, 6}.

The event that X<3 and the event that X>3 cannot occur simultaneously in the same outcome.

In an outcome, its either one of the following happens:

  • Number of heads = Number of Tails =3
  • Number of heads < Number of Tails
  • Number of heads > Number of Tails
  • Number of heads cannot be greater than Number of Heads

Therefore, the events that X<3 and X>3 are independent.
