Out of some students appeared in an examination,
80% passed in English, 75% passed in Science and
5% failed in both subjects. If 300 of them were
passed in both subjects, how many students were
appeared in the examination? Find it by using a
Venn-diagram
(Ans: 500
Answers
Answer:
500 students appeared in the examination.
Step-by-step explanation:
Each event represents a set in the Venn diagram, and we use it to find the desired values.
I am going to say that:
Event A: Passed in English.
Event B: Passed in Science.
80% passed in English
This means that [tex]P(A) = 0.8[/tex].
75% passed in Science
This means that [tex]P(B) = 0.75[/tex]
5% failed in both subjects.
This means that 100% - 5% = 95% passed at least one of these subjects, so [tex]P(A \cup B) = 0.95[/tex].
Proportion that passed both subjects:
This is [tex]P(A \cap B)[/tex]
These percentages are related by the following equation:
[tex]P(A \cap B) = P(A) + P(B) - P(A \cup B)[/tex]
So
[tex]P(A \cap B) = 0.8 + 0.75 - 0.95 = 0.6[/tex]
Number of students in class:
60% of the total number t passed both subjects. This is equals to 300. So
[tex]0.6t = 300[/tex]
[tex]t = \frac{300}{0.6}[/tex]
[tex]t = 500[/tex]

Triangle RST has vertices R(–1, 1), S(3, 1), and T(3, –4). What
are the coordinates of the image of RST after a translation 4 units to the left and 2 units down?
Answers
Answer:
R'(-5, -1) S'(-1, -1) T'(-1,-6)
Step-by-step explanation:
because the triangle is moving to the left, you subtract the number of units from the x coordinates of each vertex of the triangle. becasue the triangle is moving down, you subtract the number of units moved down from the y coordinates of each vertex.

PLEASE HELP ME QUICKLY!! The graph shows the number of eggs a farmer collected from each chicken pen one morning. How many more eggs were collected from pen 3 than from pen 2 & 5? (Each egg = 5 eggs)
Answers
Answer:
Pen 2 = 5 eggs
Pen 3 = 25 eggs
Pen 5 = 10 eggs
It is asking how many MORE eggs does pen 3 have from BOTH pens 2 and 5. Add 2 and 5. But remember one egg = 5 eggs so as stated in the beginning pen 2 has 1 egg which equals 5 eggs and pen 5 has 2 eggs which equals 10.
5 + 10 is?
15, exactly. So how many more eggs does pen 3 have? 15 + one more egg is 20 and pen 3 has 25 which is more than 20 so let’s add another egg which again equals 5.
Now we have 25 eggs, the exact amount pen 3 has. The answer is 2 more eggs/10 more eggs.

In ΔSTU, s = 150 cm, t = 430 cm and u=470 cm. Find the measure of ∠U to the nearest degree.
Answers
Answer: 96∘
Step-by-step explanation:
The measure of angle U is 96°.
What is a triangle?It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.
We have,
s = 150 cm
t = 430 cm
u = 470 cm
The Cosine rule of a triangle.
a² = b² + c² - 2bc Cos A
Now,
u² = s² + t² - 2st Cos U
Cos U = (s² + t² - u²) / 2st
Cos U = (22500 + 184900 - 220900) / 129000
Cos U = -0.10
U = 95.7
U = 96°.
Thus,
The angle U is 96°.
