Of the students in the college, 60% of the students reside in the hostel and 40% of the students are day scholars. Previous year result reports that 30% of all students who stay in the hostel scored A Grade and 20% of day scholars scored A grade. At the end of the year, one student is chosen at random and found that he/she has an A grade. What is the probability that the student is a hostlier?
Answer:
9 / 13
Step-by-step explanation:
From the question :
Let :
Hostel students = h
Day students = d
Students with A grade = a
P(h) = 60% = 0.6
P(d) = 40% = 0.4
P(hostel with A grade) ; P(A / H) = 0.3
P(day with A grade) ; P(A / D) = 0.2
The probability that a student picked at random withbA grade is an hostel student is given as :
Probability of being an hostel student gun he has A :
P(H | A) = (P(A/H) * P(H)) ÷ P(A/H) * P(H) + P(A/D) * P(D))
P(H | A) = (0.3 * 0.6) ÷ ((0.3*0.6) + (0.2*0.4))
P(H | A) = 0.18 ÷ (0.18 + 0.08)
P(H | A) = 0.18 ÷ 0.26
P(H | A) = 9 / 13
David is an enthusiastic cyclist. He uses an app on his phone to track each of his cycling sessions below is shown some information about his last three
The required diagram is attached in the picture below :
Answer:
15.05 miles
2 :09:12
5 hours 19 minutes 18 seconds
Step-by-step explanation:
Given :
28/4/18:
Time : 1 :03 : 25
Fastest mile = 02 : 25
Distance = 15.05 miles
03/5/18:
Time : 2:06: 41
Fastest mile = 02 : 53
Distance = 28.70 miles
08/5/18:
Time : 2 :09:12
Fastest mile = 02 : 45
Distance = 26.39 miles2
1.) shortest distance cycled :
From the data:
15.05 < 26.39 < 28.70
Shortest distance cycled = 15.05 miles
The longest the cycled:
1 :03 : 25 < 2:06: 41 < 2 :09:12
Longest = 2 :09:12
Total cycling time :
1 :03 : 25 + 2:06: 41 + 2 :09:12
(1 + 2 + 2)= 5 hrs
(03 + 06+ 09) = 18 minutes
(25 + 41 + 12) = 78 seconds = 1 minute 18 seconds
18 minutes + 1 minute = 19 minutes
Total = 5 hours 19 minutes 18 seconds

Solve the following question using the elimination method :)
the mod

28 in
Approximately how much cardboard did he use in all to make the model?
828 square inches
1,092 square inches
О
1,400 square inches
o
2,016 square inches
о
Answer:
Step-by-step explanation:
base = 784 sq in² 28 in tall pyramid
each side of the square base = √784 also equals 28
using the Pythagorean theorem the length of each side of the pyramid from the base to the point is
(side/2)² + height² =( length of the pyramid face)²
(28/2)² + 28² = 196 + 784 = 980 = (face length)²
face length = √980 = 31.3
area of the pyramid = 4 sides × area of each face + the area of the base
= 4×[(1/2)(base)(face length)] + side²
= 4(1/2)(28)(31.3) + 784
= 2537 sq in² Not in the solution set
Angle DEF is similar to angle JKL.Find the length of JL and KL? First triangle DF 12.4cm DE 4cm EF 9cm other triangle JK 3cm JL ? KL ?
Answer:
KL = 6.75cm
JL = 9.3cm
Step-by-step explanation:
SInce Angle DEF is similar to angle JKL.
Then;
DE/EF = JK/KL
Given
DE = 4cm
JK = 3cm
EF = 9cm
Substitute
4/9 = 3/KL
4KL = 27
KL = 27/4
KL = 6.75cm
Similarly
DF/EF = JL/KL
12.4cm/9 = JL/6.75
9JL = 12.4 * 6.75
9JL = 83.7
JL = 83.7/9
JL = 9.3cm
Write a function rule for "The output is 7 less than three times the input." Use x for the independent variable and y for the dependent variable. I need help
Answer:
f(x) = 3x - 7
Step-by-step explanation:
Let the independent variable of a function is 'y' and dependent variable 'x'.
Therefore, function will be in the form of y = ax - b
Now statement given in the question states that "The output is 7 more than 3 times the input."
That means y is 7 less than 3 times of x.
y = 3x - 7
Rewrite this equation in the form of a function.
f(x) = 3x - 7
Convert the fraction below into a decimal: 7 3/4
Answer:
7.75
Step-by-step explanation:
7 is a whole so stays as such, 1/4 is 0.25 so 3/4 is 0.75

Answer: C
Step-by-step explanation: you multiply all your numbers together to get 420 and then you divide by 2 because it is half of a rectangle to get 210.
The Pythagorean Theorem is
c² = g²-6²
False
O True
O No answer text provided.
O No answer text provided.
Answer:
FalseStep-by-step explanation:
It depends on the triangle.
If a is the longest side then it's true, but usually when we talk about Pythagorean theorem we mean that c is the longest side of the right triangle. So:
c² = a² + b²Solve using the appropriate formula. Substitute 3.14 for π. Hint: Circle: A = πr2 Find the area of a circle with a radius of 4 cm.
Answer:
The area of a circle is [tex]\pir^{2}[\tex] and the radius is 4 so we have 16π and substituting 3.14 for pi we get 50.24 .

Answer:
6=28 1=125
Step-by-step explanation:
65+59=124 180-124=56/2 equals 28 and if the question is correctly written
then both sides that you don't yet know should be 28
The answer for one if I'm correct is 125 since you add 204+31=235 then you do 360-235=125

Solve for x. 6x-20 4x+50
Answer: Simplifying
4x + 50 = 6x + 20
Reorder the terms:
50 + 4x = 6x + 20
Reorder the terms:
50 + 4x = 20 + 6x
Solving
50 + 4x = 20 + 6x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-6x' to each side of the equation.
50 + 4x + -6x = 20 + 6x + -6x
Combine like terms: 4x + -6x = -2x
50 + -2x = 20 + 6x + -6x
Combine like terms: 6x + -6x = 0
50 + -2x = 20 + 0
50 + -2x = 20
Add '-50' to each side of the equation.
50 + -50 + -2x = 20 + -50
Combine like terms: 50 + -50 = 0
0 + -2x = 20 + -50
-2x = 20 + -50
Combine like terms: 20 + -50 = -30
-2x = -30
Divide each side by '-2'.
x = 15
Simplifying
x = 15

She square was 10 ft by 10 ft. Suppose uses the same amount of fencing to enclose a circular area. What is the area of the circle? Use 3.14 for .
Answer:
127.41ft^2
Step-by-step explanation:
Given data
DImension of the square
10ft by 10ft
The perimeter of the square is
=10+10+10+10
=40ft
Hence the amount of the fencing of the circle is 40ft
That is the circumference is 40ft
C=2πr
solve for r
40=2*3.14*r
40=6.28r
r= 40/6.28
r=6.37 ft
Area= πr^2
Area= 3.14*6.37^2
Area= 3.14*40.5769
Area= 127.41ft^2

Which statement best describes where the StartFraction pi Over 4 EndFraction comes from in the formula derivation? It is the ratio of the area of the square to the area of the circle from a cross section. It is the ratio of the area of the circle to the area of the square from a cross section. It is the difference of the area of the square and the area of the circle from a cross section. It is the sum of the area of the square and the area of the circle from a cross sectio
Answer:
Adding 12 to the circle area is equal to the square area.
Or
s2 = 12 + A
Where
s = side of square
A = area of circle
So
s2 = 12 + 36
s2 = 48
Solve this for s to get the side length
