1, In a class of 80 students in Debreberhan University, 45 are good in mathematics, 15 are good in both mathematics and in Engli

Aleks [24]

Treating the data as a Venn set, it is found that:

26 students are good in mathematics only.

28 students are not good in any of the three courses.

---------------------------------

I am going to say that:

A is the number of students good in Math.
B is the number of students good in English.
C is the number of students good in Psychology.

---------------------------------

9 are good in all of the three courses.

This means that: $A \cap B \cap C = 9$

---------------------------------

13 are good in both mathematics and psychology

This means that:

$(A \cap C) + (A \cap B \cap C) = 13$

$(A \cap C) + 9 = 13$

$(A \cap C) = 4$

---------------------------------

15 are good in both mathematics and in English

This means that:

$(A \cap B) + (A \cap B \cap C) = 15$

$(A \cap B) + 9 = 15$

$(A \cap B) = 6$

---------------------------------

16 are good in both English and psychology

This means that:

$(B \cap C) + (A \cap B \cap C) = 16$

$(B \cap C) + 9 = 16$

$(B \cap C) = 7$

---------------------------------

20 are good in psychology

This means that:

$c + (A \cap C) + (B \cap C) + (A \cap B \cap C) = 20$

$c + 4 + 7 + 9 = 20$

$c = 0$

---------------------------------

45 are good in mathematics

This means that:

$a + (A \cap B) + (A \cap C) + (A \cap B \cap C) = 45$

$a + 6 + 4 + 9 = 45$

$a = 26$

---------------------------------

Question a:

$a = 26$ , which means that 26 students are good in mathematics only.

---------------------------------

Question b:

At least one is:

$a + (A \cap B) + (A \cap C) + (B \cap C) + (A \cap B \cap C) = 26 + 6 + 4 + 7 + 9 = 52$

Thus, 80 - 52 = 28

28 students are not good in any of the three courses.

How many solutions does 5x - 3 = 5 (x - 1) have?

Oliga [24]

Answer:

C. No solutions

Step-by-step explanation:

5x - 3 = 5 (x - 1)

5x - 3 = 5x - 5

* so they have the same slope but different y-intercepts. So they would be parallel lines and they would never intercept meaning. No Solutions!
