Answer :
The probability of obtaining a head in a single toss is will be 0.5
Step-by-step explanation:
According to the empirical definition of probability, by continuing to increase the number of trials, it would ultimately get very close to a number which the probability of obtaining a head in a single toss of the coin. This number is known to be 1/2 or 0.5
<span>3y+2x=6
5y-2x=10
--------------add
8y = 16
y = 2
</span>3y+2x=6
3(2)+2x=6
6 + 2x = 6
2x = 0
x = 0
answer: x = 0 and y = 2 or (0,2)
Answer:
e. 
Step-by-step explanation:
It is given that,
The density of intergalactic space material is 
kg per cubic meter.
And the volume of intergalactic space material is 
So the mass of that much intergalactic space material is,
, where 'm' is the mass, and 'v' is the volume.
Putting the values we get,
It is also given that the mass of lead is the same as the mass of the intergalactic space material. Therefore, the mass of lead is 
So the volume of lead is,
So the volume of lead is 
.

Step-by-step explanation:
A bar chart is a graph with rectangular bars. The graph usually compares different categories. Although the graphs can be plotted vertically (bars standing up) or horizontally (bars laying flat from left to right), the most usual type of bar graph is vertical.
The horizontal (x) axis represents the categories; The vertical (y) axis represents a value for those categories. In the graph below, the values are percentages.
