When solving a system of two linear equations

Mathematics
1 answer:
soldier1979 [14.2K]3 years ago
7 0

Answer:

When both equations have the same slope, but not the same y-intercept, they'll be parallel to each other and no intersections means no solutions. When both equations have different slopes than regardless of the y-intercept they'll intersect for certain, therefore it has exactly one solution.

If the probability of a student taking a calculus class is 0.10, the probability of taking a statistics class is 0.90, and the p
Stells [14]

Answer:

93% probability of a student taking a calculus class or a statistics class

Step-by-step explanation:

We solve this problem building the Venn's diagram of these probabilities.

I am going to say that:

A is the probability that a student takes a calculus class.

B is the probability that a student takes a statistics class.

We have that:

A = a + (A \cap B)

In which a is the probability that a student takes calculus but not statistics and A \cap B is the probability that a student takes both these classes.

By the same logic, we have that:

B = b + (A \cap B)

The probability of taking a calculus class and a statistics class is 0.07

This means that A \cap B = 0.07

The probability of taking a statistics class is 0.90

This means that B = 0.9. So

B = b + (A \cap B)

0.9 = b + 0.07

b = 0.83

The probability of a student taking a calculus class is 0.10

This means that A = 0.1

A = a + (A \cap B)

0.1 = a + 0.07

a = 0.03

What is the probability of a student taking a calculus class or a statistics class

A \cup B = a + b + A \cap B = 0.03 + 0.83 + 0.07 = 0.93

93% probability of a student taking a calculus class or a statistics class

in how many year will rs 8000 amount to rs 13824 at 20% per annum interest compounded annually? please please help me out​
icang [17]

Answer :-

<h3>3 years</h3>

step by step explanation:-

Let the time be x

principal = rs 8000

Amount = rs 13824

rate = 20% p.a

A = P(1+r/100)^n

13824 = 8000 ( 1 + 20/100)^n

=> 13824/8000 = (120/100)^n

=> 13824/8000 = (24/20)^n

=> (24/20)³ = (24/20)^n

=> 3 = n

=> n = 3 years

Find the values of x,y,z. This diagram is not a scale.
Serjik [45]

Important:
                             The sum of the three angles inside
                              every triangle is always 180°.


First, look at the left triangle alone.
Two of its angles are 46° and 58° .  (46° + 58° ) = 104°
That leaves (180° - 104° ) = 76° degrees for the third angle.
The third angle in that triangle is 'x'. 
                                                         x = 76° .

At the point where 'x' and 'z' come together:
'x' and 'z' are a "linear pair".
Placed side-by-side, they form a straight line.
So (x + z) = 180° .
But  x = 76°.
So z = (180° - 76°).              z = 104° .

Now look at the the skinny triangle on the right alone.
The angle at the top is 13°, and  z = 104°. 
(13° + 104°) = 117° . 
That leaves (180° - 117°) = 63° for the third angle.
'y' is the third angle.
                                                 y = 63° .
