This is very simple, you can use tally marks to find the amount of birthdays. Then divide it by 100. Good luck !
Answer:
The answer is 180 degrees.
Step-by-step explanation:
The rotation that maps one side to an adjacent side is 360°/6 = 60°. This is the least rotation that plots the regular hexagon to the aforementioned. In the least whole number of these minimum rotations, such as three 60° rotations to make 180°, will retain the hexagon identical.
Please mark me brainliest and have a awesome day! :D
Break it down into 2-Dimensional shapes. Then add the areas together.
From the picture you can see;
front & back rectangles are 2*(4 x 8) = 64 m²
2 side rectangles are 2*(4 x 12) = 56 m²
2 triangular front & back pieces are (1/2)*8*3 = 12 m²
2 roof rectangles are 2*(5 x 12) = 120 m²
total Surface area = 64 m² + 56 m² + 12 m² + 120 m²
= 252 m²
For the volume; break it up into 3-dimenssional shapes and add the volumes together.
From the picture you can see;
Rectangular box volume is 4 x 8 x 12 = 384 m³
Triangular roof volume is area of front triangle multiplied through the length. (1/2)*8*3* 12 = 144 m³
Total volume = 384 m³ + 144 m³
= 528 m³
Answer:
From the frequency table, let's calculate the row total.
Row total for phone call = 19 + 9 = 28
Row total for no phone call = 8 +6 = 14
To calculate their respective row relative frequencies, let's use:
Row relative freq = 
Now, the two-way frequency table will be computed as:
For phone call:
Desirable behavior = 
≈0.69
Undesirable behaviour = 
≈0.32
No phone call:
Desirable behaviour = 
≈ 0.57
Undesirable behaviour = 
≈ 0.43
The complete two-way table is attached.
Step-by-step explanation:
We will use the Thales theorem since ED and CB are parallel and A,D and B are in the same lign wich is the same for C,E and A
since we have two similar sides and one similar angle between them it will be SAS similarity
