s +h = 1070 ( total number of downloads)
Rewrite as s =1070 - h
2.9s + 4.4h = 4393 ( total download size)
Substitute:
2.9(1070-h) + 4.4h = 4393
Simplify:
3103 - 2.9h + 4.4h = 4393
Combine like terms:
3103 + 1.5h = 4393
Subtract 3103 from each side:
1.5h = 1290
Divide both sides by 1.5:
h = 1290 / 1.5
h = 860
Replace h with 860 in first equation to solve for s:
s + 860 = 1070
s = 1070 - 860
s = 210
There were 210 standard downloads and 860 high quality downloads
Answer:
E A F
Step-by-step explanation:
5/8 . 3/2 is 15/16
So the answer is D
To calculate mean: Just add up all the numbers, then divide by how many numbers there are.345 + 673 + 728 +775 + 822 +827 +839 + 951 = 5960/8 = 745
633 + 673 + 728 +775 + 822 +827 +839 + 951 = 6248/8 = 781781- 745 = 35 It increases by 35To find the Median, place the numbers in value order and find the middle. BUT, with an even amount of numbers things are slightly different. In that case we find the middle pair of numbers, and then find the value that is half way between them. This is easily done by adding them together and dividing by two. 345 673 728 775 822 827 839 951 The median = 822-775 /2
The median =23.5After the change633 673 728 775 822 827 839 951 The median = 822-775 /2
The median =23.5The median stays the same.
The solution will be: 
<em><u>Explanation</u></em>
The given inequality is: 
First we will subtract 
from both sides. So.....
Now we will subtract 13 from both sides. So.....
Then we need to divide both sides by -3. As here we are <u>dividing the inequality by a negative number, so we need to switch the inequality symbol</u>. So, we will get.......
Thus, the solution will be:
