Which statement proves that quadrilateral JKLM is a kite?
sesenic [268]
A quadrilateral is a kite if the diagonals are:

i) perpendicular
ii) bisect each other
iii) not equal ( together with conditions i and ii this would make the quadrilateral a square)


Another definition of the kite is :

a quadrilateral with 2 pairs of equal adjacent sides.


Let's check the choices one by one:

A. <span>∠M is a right angle and MK bisects ∠LMJ.

according to these, ML and MJ may well be not equal...


</span><span>B. LM = JM = 3 and JK = LK = √17.
</span>
this makes the quadrilateral a kite.


<span>C. MK intersects LJ at its midpoint
</span>
if they are not perpendicular, the quadrilateral is not a kite.


<span>D. The slope of MK is –1 and the slope of LJ is 1.

this only means that MK and LJ are perpendicular, but not whether they bisect each other,

There are a total of 21 students in the choir and the drama club. There are 7 more students in the choir than the drama club. Wr
PolarNik [594]

Answer:

<em>The number of students in the drama club is 7 and the number in the choir is 14</em>

Step-by-step explanation:

X = Number of students in choir club

Y =  Number of students in drama club

<u>First equation:</u>

x + y = 21

<u></u>

<u>Since we know that there are 7 more students in the choir club than the drama club, that means:</u>

x + 7 = y

<u>A little trick that you can do to find y is this:</u>

21 students in the choir and drama club - 7

=> 14

Meaning that y is 14

<u>So lets go back into our second equation:</u>

x + 7 = 14

7 + 7 =14

x=7

<u>Plug both variables in:</u>

7 + 14 = 21

So that means that there are 7 students in the drama club and 14 students in the choir club.

yan [13]

Answer and Step-by-step explanation: Standard Deviation is the measure of how diferent a number is from the mean of the data set. It is the spread of a data set. To calculate it manually:

1) Find the mean of the data set. Mean, represented by μ, is the sum of all the values divided by the total number of elements forming the set;

2) Subtract each number with the Mean and square the result;

3) Add the differences and divide it by the total number of elements of the set;

4) Take the square root of the result and that is the <u>Standard</u> <u>Deviation.</u>

The calculations can be done by a calculator like Excel:

1) In each cell of a same column, write the data you want to know the deviation.

2) On the last cell, write: =stdev.p(A1:A10) or =stdev.s(A1:A10).

3) Press Enter. The deviation will appeared on the same cell.

The function STDEV.P is used when the data represents the entire population, whereas STDEV.S is used when the data is for a sample of the population. Inside the parenthesis, put the cells where your data is. For example, if you put your data in the column A, from cell 1 to cell 10, you write like it's written above.
