A car listens plate is made up of 7letters or numbers, where the numbers are whole numbers 0-9.

Studentka2010 [4]

There is 26 letters and 10 numbers, so a possibility of 36 different characters for each one

so probability of the first character being a number would be 10/36 as a fraction and 0.2777 ( the seven keeps repeating) as a decimal

rounded to nearest hundredth would be 0.28

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.

Find the solution of this system of equations - 10x - 6y = -56 - 10x - y = -76

sladkih [1.3K]

Answer:

10 x -6y = -76

-56 - 10x - y = -76

10x - 6y = -76 (-56) - (-76) = 20

-10 x -y = -20

10x - 6y = -76

-10x -y =-20

10x cancels

76 + 20 = 96

-7y = - 96

divide both sides by -7

y = 96/7

substitute into -10x - y = - 20

- 10x - 96/7 = - 20

96/7 is a fraction btw

= -10 x = - 20 + 96/7

-20 + 96/7

-10 x = -44/7

divide by - 10

x = 22/ 35 ( a fraction)

(x,y) = (22/ 35) ( 96/7)

8. $700 at 8% for 6 years.

it could mean
1. compound interest
2. simple interest.

1. Compound Interest

that means that each year it gives you 8% on that whatever new thing so
8 %= 0.08
Each year, it is multiplied by 1.08 since you add the original (1) to the 8% 0.08
so 6 years means
700 times 1.08^6=700 times 1.08 times 1.08 times 1.08 times 1.08 times 1.08 times
1.08 = 1110.81

2. Simple Interest

So just 8% of that 700 is added on
find 8% of 700
8% of 700+0.08 times 700=0.56
6 years = 0.56 times 6 =3.36
add 3.36 + 700= 703.36

Answers are
if compound interest = $1110.81
If Simple interest = 703.36

I hope this helped
