Answer:
Here, we want to calculate the probability that a student selected is a senior student or one that drives to school.
From the table, the number of senior students is 25 + 5 + 5 = 35
So the probability of selecting a senior student is 35/100 = 7/20
Now the probability of selecting a student that drives to school.
The number of students that drive to school is 2 + 13 + 25 = 40
So the probability of a student who drives to school is 40/100
Kindly recall that when we have or and we are dealing with probability, we add the concerned terms together
Thus the probability of randomly selecting a student who is a senior or drives to school = Probability of being a senior + Probability of driving to school = 35/100 + 40/100 = 75/100 = 3/4

calculate the ratio of the velocity of molecular nitrogen gas to the velocity of carbon dioxide gas at the same temperature.
The ratio of the velocity of molecular nitrogen gas to the velocity of carbon dioxide gas at the same temperature is 0.045.
What is speed?The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.
We know that the speed formula
[tex]\rm v = \sqrt{\dfrac{3RT}{M}}[/tex]
where R is the universal gas constant and M is the molar mass.
Then the ratio of the velocity of molecular nitrogen gas to the velocity of carbon dioxide gas at the same temperature.
The molar mass of nitrogen will be
N₂ = 14 × 2 = 28
The molar mass of carbon dioxide will be
CO₂ = 12 + 16 × 2 = 44
Then we have
[tex]\rm \dfrac{v_{N_2}}{v_{CO_2}} = \dfrac{\sqrt{\frac{3RT}{28}}}{\sqrt{\frac{3RT}{44}}}\\\\\\\dfrac{v_{N_2}}{v_{CO_2}} = \sqrt{\dfrac{44}{28}}\\\\\\\dfrac{v_{N_2}}{v_{CO_2}} = 0.04477 \approx 0.045[/tex]

Altitudes $\overline{ad}$ and $\overline{be}$ of acute triangle $abc$ intersect at point $h$. if $\angle ahb = 128^\circ$ and $\angle bah = 28^\circ$, then what is $\angle hca$ in degrees?
The Angle HCA is equal to 52°. This is arrived at using the knowledge of the Total value of Angles in a Triangle and the Total Value of Angles in a Polygon.
What other principles were used to arrive at the answer?
The other principles of mathematics that were used to arrive at the above answer are:
Total Angles on a straight line; Total Angles on a point; and Line segments.What are the Steps to the Solution?Step 1 - Recall that we have been given Angles AHB and BAH to be 128° and 28° respectively.
We also know that:
The sum of angles in a triangle is 180°;...................AThe sum of angles on a straight line is 180°;.........BThe sum of angles in a polygon is 360°; while.....CThe total sum of angles at a point is 360°.............DSince A...therefore:
When ∠AHB (128°) and ∠BAH are taken from 180° we have DBA = ∠28°.
By observation, we can deduce that ∠BDE, ∠CDH, ∠CEH and ∠AEH are all right-angled triangles.
Using the above, we are able to repeat this process of solving for each angle until we have ∠HCA.
To verify that our answer is correct, recall that sum of angles in a polygon is 360°
That means:
∠BDA + ∠DHE + ∠CEH + ∠HCA = 360°
That is, 90+ 128 + 90 + 52 = 360°

Answer:The Soviet Union invaded Afghanistan caused relations to deteriorate between the United States and the Soviet Union in 1979.
Explanation:
The Soviet Union, officially the Union of Soviet Socialist Republics, was a socialist and communist state that spanned much of Eurasia from 1922 to 1991. It was nominally a federal union of fifteen national republics; in practice its government and economy were highly centralized until its final years. The country was a one-party state governed by the Communist Party of the Soviet Union, with Moscow as its capital within its largest and most populous republic, the Russian SFSR. Other major urban centers were Leningrad, Kiev, Minsk, Tashkent, Alma-Ata and Novosibirsk. It was the largest country in the world, covering over 22,402,200 square kilometres, and spanning eleven time zones.
The Soviet Union invaded Afghanistan to help its communist government.
What is Soviet Union?The Soviet Union, officially known as the Union of Soviet Socialist Republics (USSR), was an Eastern European and northern Asian federal socialist state that existed from 1922 to 1991.
It was the world's largest country by land area, covering over 22 million square kilometres, and was made up of 15 republics.
The Soviet Union invaded Afghanistan in 1979 to support the communist government in power at the time.
The Soviet intervention was met with opposition from Afghan rebel forces known as the Mujahideen, who were backed by the US and other Western countries.
Thus, the conflict lasted more than a decade and ended with the withdrawal of Soviet forces in 1989, but the consequences for both Afghanistan and the Soviet Union were long-lasting.
