The mean height of the basketball players is 80.3 inches

For given question,

we have been given the list of heights, in inches, for a sample of college basketball players.

We need to find the mean height of the basketball players.

We know that, for given sample of data

mean = sum of all observations ÷ total number of observation

First we find the sum of given heights.

78 + 83 + 82 + 78 + 78 + 80+ 81 +79+ 79 +83+ 77 +78+ 84+ 82+ 80+ 80 +82+ 84+78+ 80 = 1606

Total number of observations = 20

Using the formula of mean,

⇒ mean height = 1606/20

⇒ mean height = 80.3 inches

Therefore, the mean height of the basketball players is 80.3 inches

Which of the following best completes the proof showing that ΔWXZ ~ ΔXYZ?
skelet666 [1.2K]

Angles formed by the segment \overline{XZ} in the triangles ΔWXZ, and ΔXYZ, are equal and the given corresponding sides are proportional.

  • The option that best completes the proof showing that ΔWXZ ~ ΔXYZ is; <u>16 over 12 equals 12 over 9</u>

Reasons:

The proof showing that ΔWXZ ~ ΔXYZ is presented as follows;

Segment \overline{XZ} is perpendicular to segment \overline{WY}

∠WZX and ∠XZY are right angles by definition of \overline{XZ}  perpendicular to \overline{WY}

∠WZX in ΔWXZ = ∠XZY in ΔXYZ = 90° (definition)

\displaystyle \frac{WZ}{XZ} = \frac{16}{12} = \mathbf{ \frac{4}{3}}

\displaystyle \mathbf{ \frac{XZ}{ZY}}  = \frac{12}{9}  = \frac{4}{3}

Therefore;

  • \displaystyle \frac{16}{12} = \frac{12}{9}, which gives, \displaystyle \mathbf{\frac{WZ}{XZ} }= \frac{XZ}{ZY}

Given that two sides of ΔWXZ are proportional to two sides of ΔXYZ, and

that the included angles between the two sides, ∠WZX and ∠XZY are

congruent, the two triangles, ΔWXZ and ΔXYZ are similar by Side-Angle-

Side, SAS, similarity postulate.

The option that best completes the proof is therefore;

  • \displaystyle \frac{16}{12} = \frac{12}{9} which is; <u>16 over 12 equals 12 over 9</u>

Students found that a box with sides 4cm, 4cm, and 5 cm held 192 Skittles.
zloy xaker [14]

Answer:

Volume = 80 cm³

Ratio = 24:5  

Volume of each skittle = 0.411 cm³/skittle

Step-by-step explanation:

Given:

Sides of the boxes = 4 cm , 4 cm and 5 cm

Total Skittles hold = 192 skittles

To Find:

Volume = ?

Ratio of skittles to volume = ?

Volume of each skittle = ?

Solution:

Volume of a box is given by the formula

Volume = Length * width * Height

Putting in the values

Volume = 4 * 4 * 5

             = 80 cm³

Now to find Ratio of skittles to Volume of box which is

Skittles : Volume  = 192 : 80

As 192 and 80 both are divisible by 8 so dividing them by 8

                              = \frac{192}{8}:\frac{40}{8}

                               = 24:5

Which is the required ratio

Now we have to find volume of each skittle so it could be found out by dividing total volume with total skittles

So

Volume of each skittle =\frac{total Volume}{Total Skittles}

Putting in the values gives

                                       =\frac{80}{192}

it becomes

                                             = 0.411 cm³/skittle
