Answer:
Speciation occurred as species got separated by seas and oceans.
Explanation:
The breakup of Pangaea into Laurasia and Gondwanaland resulted in clade dispersal, isolation of clades, and change in the climate. It also influences patterns of diversity. Only those animals that survived the mass extinction that was able to adapt to the new climate conditions. Speciation occurred as species got separated by seas and oceans.
The answer is (A) Greg’s education was covered by a donation, and Hunter’s education was covered by taxes.
This is due to the fact that Greg has a benefactor, which is <em>someone who gives his or her money to help another person</em> – in this case, the benefactor is donating their money for Greg’s private schooling.
In Hunter’s case, he doesn’t have to pay for tuition because his public school students' tuition is paid using the citizen’s taxes.
Answer:
Explanation:
Given the data:
X ___ : 0____ 1 ___ 2 ____ 3 ____ 4
P(X)__: 0.35_0.3___, b ___0.05_ 0.05
Σp(x) = 1
Hence,
0.35 + 0.3 + b + 0.05 + 0.05 = 1
0.75 + b = 1
b = 1 - 0.75
b = 0.25
The mean :
E(x) = Σ(X * p(x))
E(x) = (0*0.35)+(1*0.3)+(2*0.25)+(3*0.05)+(4*0.05)
E(x) = 0 + 0.3 + 0.5 + 0.15 + 0.2 = 1.15
Standard deviation = sqrt(Var(x))
Var(x) = Σx²p(x) - E(x)
Σx²p(x) = (0^2 * 0.35)+(1^2 * 0.3)+(2^2 * 0.25)+(3^2 * 0.05)+(4^2 * 0.05)
= 2.55 - 1.15
= 1.4
Sqrt(1.4) = 1.183
Answer:
A bar diagram makes it easy to compare sets of data between different groups at a glance.
The graph represents categories on one axis and a discrete value in the other. The goal is to show the relationship between the two axes.
Bar charts can also show big changes in data over time.
Explanation:
You measure the paper you are using to draw the map on and you measure the size of the country you are putting on your paper, then you can calculate the measurements and divide by how much states can fit in on your paper.
