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= \frac{(551+1683+....+586)}{7} =3610

Median proves middle value or class so if ascending data is arranged = 4th term = 4053 

A mode is of max = 3_{median} -2_{mean} = 4939

Range It is also the difference between max and min values which indicates the overall distribution range = 5868 -551=5317

The standard deviation= 1841.60

AnnZ [28]

Answer: 140 Hot dogs and 83 sodas.


Step-by-step explanation:

Alright, so we will say that h = hot dogs and s = sodas.

h + s = 223

I have used the guess and test strategy to get:

h = 140

140 - 57 = 83

s = 83

Check: 83 + 140 = 223

In parallelogram DEFG, DH = x + 3, HF = 3y, GH = 2x – 5, and HE = 5y + 2. Find the values of x and y.
eimsori [14]
Since DH=HF you set x+3=3y 
<span>GH=HE so 4x-5=2y+3 </span>

<span>This gives you a system and I solved by substitution so I got x alone in the first equation-> x=3y-3 </span>
<span>then I plugged this x into the second equation so </span>

<span>4(3y-3)-5=2y+3 </span>
<span>12y-12-5=2y+3 </span>
<span>12y-17=2y+3 </span>
<span>10y=20 </span>
<span>y=2 </span>

<span>plug y into the first equation to find x </span>
<span>x=3(2)-3 </span>
<span>x=6-3 </span>
<span>x=3 </span>

<span>c. x=3, y=2</span>
