Answer:
Following are the responses to these questions:
Step-by-step explanation:
In point a:
Please find the graph file in the attachment.
In point b:
This information is interesting for us, because we inform us about an important disease outbreak in such days and how the pandemic impacts major global communities like London as well as how the pattern in the recorded cases is increasing and decreasing.
In point c:
The data are sorted: 551, 1683, 3194, 4053, 4079, 5842, 5868
Mean
Median proves middle value or class so if ascending data is arranged = 4th term = 4053
A mode is of max 
Range It is also the difference between max and min values which indicates the overall distribution range 
The standard deviation
Answer with Step-by-step explanation:
We are given that
Height of radio tower =650 ft
From figure
AB=650 ft
BC=180 ft
We have to find the AC.
Using cosine law:



Hence, a guy required 643.64 ft wire when it is to connect to the tower and be secured at a point on the sloped side 180 ft from the base of the tower.
b.In a right triangle ABC, AB=
Pythagorous theorem :
Substitute the values



Hence, the length of wire should be 371.52 ft when a second guy connect the middle of the tower and be secured at a point 180 ft from the base on the flat side by wire.
Answer:
(k+3)(k+4)
The zeros are -3 and -4
Step-by-step explanation:
k2+7k+12
The middle number is 7 and the last number is 12.
This means we need two numbers that:
Add together to get 7
Multiply together to get 12
to fit in this equation (k+_)(k+_)
in this equation, it would be 3 and 4
3+4 = 7
3*4 = 12
Now we fill in the blanks to get
(k+3)(k+4)
To get the zeros, use the equations
k+3=0 and k+4=0
You end up with
k=-3 and k=-4
