Answer:

We know that our triangle has one side along the line:

y = (1/4)*x

And other side along the line:

y = -(1/4)*x.

Now, we want to find the vertex.

And we know that the vertex is the point where the two sides conect, so the vertex must be a common point of both lines.

Then we have:

y = (1/4)*x = -(1/4)*x

x = -x

The only solution to that equation is x = 0.

now we evaluate our lines in x = 0 and get:

y = (1/4)*0 = 0

y = -(1/4)*0 = 0

Then the lines intersect in the point (0, 0)

Then the vertex must be in the point (0, 0)

So, one trillion is 1 and twelve zeros, thus 2.4 trillion is 2 trillions and 400 billions or 24 followed by eleven zeros, because the "4" is using up a space.

now, 1 million is 1 and six zeros, thus 100 millions is 100 and six zeros or 1 and 8 zeros.

now, is 2.4 trillions in four months, thus 2.4trillion/4 will give us how many gallons in 1 month.

to find how many households, simply let's divide it by 100 millions

\bf \cfrac{\stackrel{\textit{2.4 trillions}}{24\times 10^{11}}}{4}\implies \cfrac{24}{4}\times 10^{11}\implies 6\times 10^{11}
\\\\\\
\cfrac{\stackrel{\textit{gallons per month}}{6\times 10^{11}}}{\stackrel{households}{1\times 10^8}}\implies \cfrac{6}{1}\times \cfrac{10^{11}}{10^8}\implies 6\times 10^{11}\times 10^{-8}
\\\\\\
6\times 10^{11-8}\implies 6\times 10^3\implies \stackrel{\textit{gallons per household}}{6000}

a group of students were surveyed to find out if they like building snowmen or skiing as a winter activity. The results of the s
Liula [17]

Answer:

2/5 or 0.4

Step-by-step explanation:

10 students like building snowmen but do not like skiing

so students who like both building snowman and skiing = 60 - 10 = 50

Total number of students who does not like building snowman and also does not like skiing = 80 - 60 = 20

Therefore, the probability that  a student who does not like building snowmen also does not like skiing = 20/50 = 0.4
