We will start with plotting the x coordinates and y coordinates on the graph

The points 1, 2; 2, 2; 3, 2; 4, 2  have been plotted on the graph which has been attached as an image to the solution.

We can see that the value of y is staying constant (2) for all values of x.

Hence, the points represent the equation y = 2.

Manu had ₹ 120. He bought one book for ₹ 25.75 and a pen for ₹ 12.50. How much money does he have now?​
adelina 88 [10]

Answer:

₹ 81.75

Step-by-step explanation:

Total =  ₹ 120.

He bought one book for ₹ 25.75 and a pen for ₹ 12.50.

    ₹ 25.75 + ₹ 12.50 =  ₹ 38.25

How much money does he have now?​

     ₹ 120 -  ₹ 38.25 =  ₹ 81.75

PLZ ANSWER FIRST GETS BRAINLIEST + 20 POINTS
sleet_krkn [62]

Answer:

x= -2, y = 5

Step-by-step explanation:

y = -4x-3

y = -2x+1

Set the two equations equal to each other

-4x-3 = -2x+1

Add 4x to each side

-4x-3 +4x = -2x+1+4x

-3 = 2x+1

Subtract 1 from each side

-3-1 = 2x+1-1

-4 =2x

Divide by 2

-4/2 = 2x/2

-2 =x

Now find y

y = -4x-3

y = -4(-2) -3

y = 8 -3

y =5

It is known that 25% of inhabitants of a community favour a political party A.
Keith_Richards [23]

Answer:

i) P(X=2)=(20C2)(0.25)^2 (1-0.25)^{20-2}=0.0669

ii) P(X=0)=(20C0)(0.25)^0 (1-0.25)^{20-0}=0.00317

P(X=1)=(20C1)(0.25)^1 (1-0.25)^{20-1}=0.0211

P(X=2)=(20C2)(0.25)^2 (1-0.25)^{20-2}=0.0669

And replacing we got:

P(X \geq 3) = 1- [0.00317+0.0211+0.0669]= 0.90883

iii) P(X

Step-by-step explanation:

Let X the random variable of interest "number of inhabitants of a community favour a political party', on this case we now that:

X \sim Binom(n=20, p=0.25)

The probability mass function for the Binomial distribution is given as:

P(X)=(nCx)(p)^x (1-p)^{n-x}

Where (nCx) means combinatory and it's given by this formula:

nCx=\frac{n!}{(n-x)! x!}

Part i

We want this probability:

P(X=2)=(20C2)(0.25)^2 (1-0.25)^{20-2}=0.0669

Part ii

We want this probability:

P(X\geq 3)

And we can use the complement rule and we have:

P(X\geq 3) = 1-P(X

And if we find the individual probabilites we got:

P(X=0)=(20C0)(0.25)^0 (1-0.25)^{20-0}=0.00317

P(X=1)=(20C1)(0.25)^1 (1-0.25)^{20-1}=0.0211

P(X=2)=(20C2)(0.25)^2 (1-0.25)^{20-2}=0.0669

And replacing we got:

P(X \geq 3) = 1- [0.00317+0.0211+0.0669]= 0.90883

Part iii

We want this probability:

P(X

And replacing we got:

P(X
