The value of the probability represented by P(Take the bus | Sophomore) is 0.83
What are conditional probabilities?Conditional probabilities are probabilities that only occurred because an event has already occurred i.e. they are dependent on the initial event
How to determine the conditional probabilities?From the table of values in the question, we have the following parameters:
Number of students that (Take the bus and Sophomore) = 25Number of students that are (Sophomore) = 2 + 25 + 3The required probability represented by P(Take the bus | Sophomore ) = [?] is then calculated as:
P(Take the bus | Sophomore) = Number of students that (Take the bus and Sophomore) divided by Number of students that are (Sophomore)
Substitute the known values in the above equation
P(Take the bus | Sophomore) = 25/(2 + 25 + 3)
Evaluate the sum in the denominator
P(Take the bus | Sophomore) = 25/30
Evaluate the above quotient
P(Take the bus | Sophomore) = 0.83
Hence, the value of the probability represented by P(Take the bus | Sophomore) is 0.83

Investment a starts with $1000 and increases its value by $80 each week. Investment b starts with $2000 and loses $50 of its value each week.After how many weeks will the two investments have the same value?
Answers
Answer:
33.3 weeks
Step-by-step explanation:
Let us represent number of weeks = w
Investment a starts with $1000 and increases its value by $80 each week.
$1000 + $80 × w
1000 + 80w
Investment b starts with $2000 and loses $50 of its value each week.
$2000 - $50 × w
2000 - 50w
After how many weeks will the two investments have the same value?
1000 + 80w = 2000 - 50w
Collect like terms
80w + 50w = 2000 - 1000
130w = 1000
w = 1000/30
w = 33.333333333 weeks
Approximately
After 33. 3 weeks, the Investment will have the same value

Answer:
n = 5 units
Step-by-step explanation:
We can solve this using 2 different equations which lead to the same answer:
Equation #1: Sin(30) = n/10
=>Sin(30) * 10 = n
=> 5 = n
Equation #2: Cos(60) = n/10
=> Cos(60) * 10 = n
=> 5 = n
If a number is a whole number, it is in it's simplest radical form, therefore; n = 5 units is the correct answer

One pump can fill a tank of water in 2 hours. A second tank can fill the same tank in 3 hours. If both pumps are used together, how long will it take to fill the tank? 5/6 hours 6/5 hours 3/2 hours 2/3 hours
Answers
Answer:
6/5 hours
Step-by-step explanation:
GIVEN :-
Lets say ,
Pump A takes 2 hours to fill the tank alonePump B takes 3 hours to fill the tank aloneTO FIND :-
Time taken by both pumps to fill the tank when used togetherPROCEDURE :-
In 2 hours , Pump A fills the whole tank.
⇒ In 1 hour , Pump A will fill 1/2 part of tank. (By using Unitary method)
In 3 hours , Pump B fills the whole tank.
⇒ In 1 hour , Pump B will fill 1/3 part of tank. (By using Unitary method)
In 1 hour , when both pumps will be used together , they will fill =
(Part of tank filled by A in 1hr) + (Part of tank filled by B in 1hr)
⇒ [tex]\frac{1}{2} + \frac{1}{3}[/tex]
[tex]=> \frac{5}{6}[/tex] part of tank
5/6 part of tank will be filled by both the pumps in = 1 hour.
Using unitary method, multiplying both the sides with 6/5 -
⇒ 5/6 × 6/5 part of tank will be filled by both the pumps in = 1 × 6/5 hours
⇒ Total tank (or 1 whole tank) will be filled by both the pumps in = 6/5 hours
∴ Both the pumps will take 6/5 hour to fill the tank , when used together.

Answer:
x = 6
y = 2
Step-by-step explanation:
From the second equation (x - 3y = 0) we know that x = 3y, now we just substitute 3y instead of "x" in the first equation and get...
x + 2y = 10
3y + 2y = 10
5y = 10
y = 2
Now we can find "x" since we know what "y" is equal to.
x + 2y = 10
x = 10 - 2y
x = 10 - (2)(2)
x = 10 - 4
x = 6

Answer:
d= 90 degrees
e= 66 degrees
f= 114
Step-by-step explanation:
D is 90 because the measure of the angle on the line is 180 and it shows that the other angle is 90 and 180- 90= 90. E is 66 because opposite angles are congruent. F is 114 because they lie on a straight line which has the measure of 180 and 180- 66= 114
Answer:
d = 90°
e = 66°
f = 114°
Step-by-step explanation:
d = 90°
e = 66°
Reason : Vertically opposite angles
Angles f and 66° are in the linear pair.
f + 66° = 180°
f = ( 180 - 66 )°
f = 114°
Use a formula to find the amount of wrapping paper you need to wrap a gift in the
cylindrical box shown. You need to cover the top, bottom, and all the way around
the box. Use 3.14 for it.
7 in. height to 9 in. radius
Answers
Answer:
100.48 square inches
Step-by-step explanation:
Surface area of a cylinder = 2πr(r+h)
r is the radius
h is the height
Given
radius = 9in
height = 7in
π = 3.14
Substitute into the formula
Surface area of the cylinder = 2(3.14)(9+7)
Surface area of a cylinder = 2*3.14*16
Surface area of a cylinder = 100.48 square inches
Hence the amount of wrapping paper you need to wrap a gift in the
cylindrical box is 100.48 square inches
53. Renee brought $60 with her to an amusement park. If admission to the park costs $25 and
games cost $3 each to play, what is the GREATEST number of games Renee can play inside the

d. 2

Renee can play 11 different games.
What are arithmetic operations?The most fundamental operations in arithmetic are addition, subtraction, multiplication, and division. However, arithmetic also includes more complex operations like manipulating percentages, square roots, exponentiation, logarithmic functions, and even trigonometric functions, which are analogous to logarithms. Other examples of more complex operations include exponentiation. Arithmetic expressions must be evaluated in accordance with the intended order of operations.
Given total amount Renee have = $60
Cost for entry in park = $25
The amount left with Renee = 60 - 25
The amount left with Renee = $35
now cost for each game is $3
total no. of games can be played in $35 = [tex]\frac{ The amount left with Renee}{ cost for each game}[/tex]
35/3 = 11.667
Hence we only count integer digits which is 11; so Renee can play 11 different games.
