Answer:
- draw lines center to vertex
- 43.5 square inches
- 261 square inches
Step-by-step explanation:
<u>Part A</u>:
The area can be decomposed into triangles by drawing a line from the center to each vertex of the hexagon.
__
<u>Part B</u>:
The area of each triangle is given by the triangle area formula:
A = (1/2)bh
A = (1/2)(10 in)(8.7 in) = 43.5 in²
__
<u>Part C</u>:
The area of the table top is 6 times the area of one triangle:
surface area = 6(43.5 in²) = 261 in²
Answer:
Step-by-step explanation:
In No.1
First you find the total number of girls which is 56-20 =36 girls in total
So to get number of boys who watched tennis 20-13=7 boys watched tennis
To get number of girls who didnt watch you do 36-17=19 girls who watched
Then add o get the totals
No.2
First you get the total number of male 80-47=33 males
Next you find the number of females doing phyisics 33-19=14 females
Next you find the number of females doing chemistry by 47-(18 + 14)=15 females
To get the number of males diong chemistry 21-15=6 males
Number of males doing biology 33-(19+6)=8
Then find the remaining totals

No. 2 (b)
Because there is a high number of students doing physics and most of them are female
Answer:
14
Step-by-step explanation:
Because the median is the middle number when the data set is in order least to greatest so you already have it in least to greatest so thank you for helping me.
and for extra just in case.
Mean=16.222
the mean= the average of the data set
Mode is 13,14
The mode is the number that appears the most in a data set and 13 and 14 appear twice.
Your range is=13
Range is the highest number subtracting the lowest number so 24 -11 which =13
Minimum is 11 because the minimum is the lowest number in data set..
Maximum is 24
Maximum is the highest number in the data set.
I hope this helps have a awesome day:)
