She spent $12 on notebooks, and she bought six notebooks.
12/6=2
Each notebook costed $2.
The best way to randomly choose the 100 families would be to allow a random number generator to come up with 100 families within a 50 radius of the amusement park.
Using this method would ensure that it is more randomised & not limited to people who come at a specific time or are in a specific area as well as it not be affected by subconscious bias of people when selecting people to survey.
Answer:
0.67
Step-by-step explanation:
<u>Solution 1</u>
We can work out the initial number by going backwards from the end:
67/1000= 0.067
0.067*100= 6.7
6.7/10= 0.67
<u>Solution 2</u>
(x*10/100)*1000= 67
x/10*1000= 67
100x= 67
x=67/100
x=0.67
Each square unit is one unit. Each triangle is half a unit.
Shape 1 has 6 units and 4 half units.
6 + 4/2 =
6 + 2 =8
Shape 1 has 8 units.
Shape 2 is almost like shape 1 but it has an extra bit which would make it larger than shape 1.
So shape 2 is larger than shape 1.
For this case, the first thing you should know is that the speed of the transfer is given by
Speed = Megabytes / time
Substituting
V = (549) / (125)
V = 4.392 mb / s
answer
the speed of the transfer was 4,392 mb / s
