F n and m are integers and n2 m2 is even, which of the following is impossible?

Answers

So, I think that you mean that

n²+m² is even? (the "plus" sign is missing, but I think this is correct).

this can only happen if either:

both n and m are even
or
both n and m are odd


That's because a sum of two expressions is even if either both or none of the expressions summed is even, and a power of a number is even only if the number is even too.

are those some of the options?

yes!
n and m are even,- possible!
 n and m are odd, -possible!
n+m is even, - possible; it would be the case if either both n and m are even or both n and m are odd n+m is odd,

so the option we'll choose is:

none of these are impossible 

The median of the data set is 81 what number is missing in data set 82, 87, 77, 70, 80, 88

Answers

The missing dataset is 81 at the 4th position.

We have the following data set -

82, 87, 77, 70, 80, 88

whose Median is -  81

We have to find out the missing data in this dataset.

What is the formula to find the Median of a set of odd number of elements (say N) ?

If a set consist of odd number of elements, then the median of that set of numbers is the is the element at the position ((N+1)/(2)) ^(th).

Let the missing element be x. Now, the data set becomes -

82, 87, 77, 70, 80, 88, x

To total number of elements in the dataset = 7, which is a odd number.

The element at the ((N+1)/(2)) ^(th) position for odd number of elements equals to Median which is equal to 81.

Hence, the missing dataset is 81 at the position -    ((7+1)/(2)) ^(th) = (8)/(2) = 4th position.

Chris is making a table top from some leftover tiles. He has 9 tiles that measure 3 1/8 inches long and 2 3/4 inches wide. What is the area he can cover with these tiles?

Answers

The area tjhat he can cover with these tiles is 77 ¹¹/₃₂ in²

Further explanation

To solve the above questions, we need to recall some of the formulas as follows:

Area of Square = (Length of Side)²

Perimeter of Square = 4 × (Length of Side)

Area of Rectangle = Length × Width

Perimeter of Rectangle = 2 × ( Length + Width )

Area of Rhombus = ½ × ( Diagonal₁ + Diagonal₂ )

Perimeter of Rhombus = 4 × ( Length of Side )

Area of Kite = ½ × ( Diagonal₁ + Diagonal₂ )

Perimeter of Kite = 2 × ( Length of Side₁ + Length of Side₂ )

Let us now tackle the problem !

Given:

Number of Tiles = N = 9 tiles

Length of Tiles = L = 3¹/₈ inches

WIdth of Tiles = W = 2³/₄ inches

Unknown:

Total Area = A = ?

Solution:

Area of One Tile.

\texttt{Area of Rectangle} = \texttt{Length} * \texttt{Width}

\texttt{Area of Rectangle} = 3 (1)/(8) * 2 (3)/(4)

\texttt{Area of Rectangle} = 8 (19)/(32) ~ \texttt{in}^2

Total Area.

\texttt{Total Area} = \texttt{Number of Tiles} * \texttt{Area of One Tile}

\texttt{Total Area} = 9 * 8 (19)/(32)

\texttt{Total Area} = 77 (11)/(32) ~ \texttt{in}^2

in order to find the area of the table top we have to multiply L*W
where L=3 1/8=25/8
W=2 3/4=11/4
A=25/8  *  11/4= (25*11)/(4*8)=275/32= 8  19/32 in squared
