Answer:
539
Step-by-step explanation:
The data downloaded in s seconds will be 94s (megabytes). Since 69 MB were already downloaded, the total is ...
m = 94s +69
When s=5, this is ...
m = 94(5) +69 = 470 +69
m = 539

Step-by-step explanation:
<u>Step 1: Define</u>
-19.2 = -3.6x + 2.4
<u>Step 2: Solve for </u><em><u>x</u></em>
- Subtract 2.4 on both sides: -21.6 = -3.6x
- Divide -3.6 on both sides: 6 = x
- Rewrite: x = 6
Answer:
Area of a circle = πr², diameter d = 2r, radius r =d/2
1. 50.24in²
2. 314in²
3. 7.065ft²
4. 60.7904yd²
5. 0.3434in²
6. 19.625cm²
(x,y)
x=right left direction
y=up down direction
we see the points (1,7) and (1,2)
they didn't move anywhere to the right or left since the first number didn't change
it went 5 units down though (7 to 2 is 5 units)
then the next one
look at the ones with same numbers in the same place
(1,7) and (6,7)
didn't move up or down but moved 5 units left and right (1 to 6 is 5 units)
(6,7) and (6,2)
didn't move left or right but moved down 5 units (7 to 2 is 5)
(6,2) and (1,2)
didn't go up or down but went 5 units down (6 to 1 is 5)
so we have that the points are 5 away from each other (the ones that are stright up and left or righ tof each other (not diagonal))
therefor the legnth of each side is 5 units
area=5^2=25
anothe way is
square has 4 sides equal
find 1 side and you found other 3
pick 2 points with same first number or second number and find difference
(1,7) to (1,2)
difference of 5 (7 to 2 is 5)
therefor area=5^2
25 square units
Answer:
a) The required sample size n= 55011,57025
b) The sample size is not practical, because that size is extremely large and would be very costly to collect, normally the size have to be significant but no to large to avoid cost unnecessary
Step-by-step explanation:
Range
⇒ 0,99
Sample size can be determinate using equation:
Using confidence level desired 99% = 2,58
Table used :
<em>Confidence </em>
<em> 90 % 1,60</em>
<em> 95 % 1,96</em>
<em> </em><em> 99 % 2,58</em>
<em> 99,9 % 3,291</em>
So replacing:
