The table below shows 10 data values:
1 answer:
Answer:
The answer is the second option
Minimum = 203, Q1 =217, median = 230, Q3 = 245, maximum = 290
Step-by-step explanation:
First order the data from lowest to highest
203, 216, 217, 224, 224, 236, 245, 245 ,262 ,290
Minimun = 203
Maximum =290
Now divide the data in half
203, 216, 217, 224, 224, 236, 245, 245 ,262 ,290
Divide half of the first half of the data. The data of the medium is the first quartile
1) 203, 216, [217], 224, 224
Q1
Divide half of the second half of the data. The data of the medium is the third quartile
2) 236, 245, [245] ,262 ,290
Q3
The average between the two values that are in the center of the 10 ordered data is the median
203, 216, 217, 224, [224, 236], 245, 245 ,262 ,290
Median=230
The answer is the second option
Minimum = 203, Q1 =217, median = 230, Q3 = 245, maximum = 290

To solve this problem, we have to apply mole-concept to this and we would need the molar mass of AlCl3. 2g of AlCl3 contains 9.034*10^21 molecules.
<h3>Number of Molecules in 2g of AlCl3</h3>The molar mass of AlCl3 is given as 133.34g/mol
Data;
- mass = 2g
- molar mass = 133.34g/mol
Using the mole concept, we can equate the molar mass to the number of molecules present in the entity.
If we equate this
From the calculations above, 2g of AlCl3 contains 9.034*10^21 molecules.

Here we go ~
1. A circle can be named by their Centre, so here in the diagram it's :
- Circle A
2. Name 4 radii :
Radii are the line segments that joins the centre and boundary of circle.
They are :
- FA
- GA
- BA
- CA
3. 2 Major arcs :
considering two points on a circle, and joining them forms a curve ( you can say part of circumference )
When we consider two points two arcs are formed and the arc with more length is known as Major Arc
That is :
- Major arc ECF
- Major arc BEC
4. A Semicircle :
Semicircle is special arc which is formed when two arcs formed by the points are equals to one another... it's also half the Perimeter of circle.
that is :
- Arc CF is a Semicircle
5. 3 minor arcs :
The arc formed by two points having lesser length is known as minor arc.
that is :
- Arc EF
- Arc BG
- Arc FG
6. 3 Central angles :
Central angles are angles formed by arcs on centre of the circle ~
that is :
- Angle FAB
- Angle BAC
- Angle GAB
7. A diameter :
Diameter is a chord that passes through centre of the circle.
- CF
8. Congruent Angles :
In the given figure, there are two equal/congruent angles that are ~
- Angle BAG and Angle GAF
9. Adjacent arcs :
The arcs that have one common end point are known as Adjacent arcs ~
that are :
- Arc FG and Arc GB
