A train leaves the station at 11 a.m. traveling at the rate of 40 miles per hour. A faster train leaves the same station at 1 p.m. that afternoon and travels in the same direction on a parallel track at a rate of 60 miles per hour. At what time will the faster train overtake the slower one
Answers
The faster train overtake the slower on 5 p.m.
How to solve such time related questions?
The key concept for solving such questions is the relationship between speed, distance and time.
The relationship between them is Distance = Speed x Time.
Let the number of hours after 1pm at which faster train will overtake slower train be x.
At overtaking point,
Distance travelled by slower train = Distance travelled by faster train
Given :
Speed of slower train = 40 miles per hourSpeed of faster train = 60 miles per hourTime taken by faster train = xTime taken by slower train = x + 2.On equating distances we get
40 x ( x + 20) = 60 x (x)
40x + 80 = 60x
20x = 80
x = 4.
∴The faster train overtake the slower on 1 + 4 = 5 p.m.

An owner of a large car lot believes that fuel prices are going to rise significantly and wonders how this rise might affect demand for the high performance vehicles. Specifically, the owner is investigating a link between how fast a car can go from 0 to 60 miles per hour (measured in seconds) and the car's economy as measured in miles traveled per gallon used (mpg). If fast cars, which are normally high in demand, are associated with higher mpg then there will be much less demand if gas prices rise as predicted. The owner gathers data on 20 vehicles.

Answers
65 sequences.
Lets solve the problem,
The last term is 0.
To form the first 18 terms, we must combine the following two sequences:
0-1 and 0-1-1
Any combination of these two sequences will yield a valid case in which no two 0's and no three 1's are adjacent
So we will combine identical 2-term sequences with identical 3-term sequences to yield a total of 18 terms, we get:
2x + 3y = 18
Case 1: x=9 and y=0
Number of ways to arrange 9 identical 2-term sequences = 1
Case 2: x=6 and y=2
Number of ways to arrange 6 identical 2-term sequences and 2 identical 3-term sequences =8!6!2!=28=8!6!2!=28
Case 3: x=3 and y=4
Number of ways to arrange 3 identical 2-term sequences and 4 identical 3-term sequences =7!3!4!=35=7!3!4!=35
Case 4: x=0 and y=6
Number of ways to arrange 6 identical 3-term sequences = 1

Answers
y = 4 is the equation of the line that represents Saturn Avenue given that Christopher decides that another road to be named Saturn Avenue is needed that will go past the cleaners and be perpendicular to Planet Drive. This can be obtained by using the formula for finding the equation of the line.
Find the equation of the line:
Equation of a line can be determined using the formula,
y = mx + c
where m is the slope of the line and c is the y - intercept.
m = rise/run = Δy/Δx = (y₂ - y₁)/(x₂ - x₁)
Here in this question draw the line passing through cleaners and perpendicular to Planet Drive.
The point where x = 0 is (0, 4)
This means that y - intercept is 4
By considering two points on the line we can find the slope of the equation,
Consider the points (8, 4) and (16, 4)
m = rise/run = Δy/Δx = (y₂ - y₁)/(x₂ - x₁)
m = (4 - 4)/(16 - 8) = 0/8 = 0
So we got that,
y - intercept of the line = 4 slope of the line = 0Putting in the equation of line we get,
y = mx + c
⇒ y = (0)x + 4 ⇒ y = 4
Hence y = 4 is the equation of the line that represents Saturn Avenue given that Christopher decides that another road to be named Saturn Avenue is needed that will go past the cleaners and be perpendicular to Planet Drive.

If A and B are independent events and P(A)=0.25 and P(B)=0.333, what is the probability P(ANB)?
a) 1.33200
b) 0.75075
c) 0.08325
d) -0.0830
Answers
The probability P(ANB), that is, P(A ∩ B), given that A and B are independent events and P(A) = 0.25 and P(B) = 0.333 is 0.08325. Hence, option C is the right choice.
For any two events A and B, the probability of event A and B, that is, P(A ∩ B) is given as:-
When the events are dependent, P(A ∩ B) = P(A).P(B|A).When the events are independent, P(A ∩ B) = P(A).P(B).In the question, we asked the probability P(ANB), that is, P(A ∩ B), given that A and B are independent events and P(A) = 0.25 and P(B) = 0.333.
We know that when the events are independent, P(A ∩ B) = P(A).P(B).
Thus, P(A ∩ B) = (0.25)*(0.333),
or, P(A ∩ B) = 0.08325.
Thus, the probability P(ANB), that is, P(A ∩ B), given that A and B are independent events and P(A) = 0.25 and P(B) = 0.333 is 0.08325. Hence, option C is the right choice.

If RT = 90, find the length of RO. (SU = 25)(SO is perpendicular to RT)
Answers
In the given figure of circle, if RT = 90, SU = 25, and SO is perpendicular to RT, the length of the radius RO is 53.
In the given figure,
RT = 90
SU = 25
SO is perpendicular to RT.
Here, SO and RO are the radii of the circle and RT is a chord.
The length of the chord, RT is given as,
RT = 2 √(r² - d²)
Here, r is the radius and d is the distance of the chord RT from the center O.
Radius, r = RO and distance, d = OU
∴ RT = 2 √(RO² - OU²)
Substituting RT = 90 in the above equation, we get,
90 = 2 √[(RO)² - (OU)²]
√[RO)² - (OU)²] = 45
(RO)² - (OU)² = 45²
(RO)² - (OU)² = 2025 ........... (1)
Now, OU = SO - SU [From the figure]
⇒ OU = SO - 25
Substituting OU = SO - 25 in equation (1), we obtain,
(RO)² - (SO - 25)² = 2025
(RO)²- [(SO)² + (25)² - 2(SO)(25)] = 2025 [ ∵ (a-b)² = a²+b²-2ab ]
(RO)²- (SO)² - (25)² + 50(SO) = 2025 ........... (2)
Since, RO and SO both are the radii of the same circle, we have,
SO = RO
Thus, we can write equation (2), as follows,
⇒ (RO)² - (RO)² - (25)² + 50(RO) = 2025
⇒ -625 + 50RO = 2025
⇒ 50RO = 2025 + 625
⇒ RO = 2650/50
⇒ RO = 53
Hence, the length of the radius RO of the given circle is 53.
