what must be added to y^2-3y​

Answers

Answer 1

Answer:

[tex](y-1.5)^2[/tex]

Step-by-step explanation:

I’m guessing you want a perfect square trinomial.

b=-3

[tex]\frac{b}{2}=-1.5[/tex]

[tex](-1.5)^2=2.25[/tex]

You need to add 2.25 to the binomial to create a perfect square trinomial.

Find the expected value of the winnings from a game that has the following payout probability distribution. Round to the nearest hundreath.

Answers

Expected value is $20.20
Step-by-step explanation:
Here, we want to calculate the expected value
What we have to do here is to multiply the probability by the payout value; after which we add all values
Thus, we have the payout value as;
1(0.12) + 4(0.2) +6(0.38) + 8(0.2) + 10(0.1)
= 0.12 + 0.8 + 2.28 + 1.6 + 1

The expected value of the winnings from a game will be [tex]2.96[/tex] .

What is Probability ?

Probability is the ratio of the number of possible outcomes to the total number of outcomes.

we have,

Payout    [tex](\$) = 0,\ \ \ 1,\ \ \ 2,\ \ \ 5,\ \ \ 10[/tex]

Probability [tex]=0.12,0.2,0.38,0.2,0.1[/tex]

So,

To find the expected value,

Now,

Multiply payout values with its probability and sum these values,

i.e.

Expected value [tex]= (0*0.12)+(1*0.2)+(2*0.38)+(5*0.2)+(10*0.1)[/tex]

                          [tex]=0+0.2+0.76+1+1[/tex]

Expected value [tex]=2.96[/tex]

Hence, we can say that the expected value of the winnings from a game will be [tex]2.96[/tex] .

A shopkeeper decided to make equal rate of profit in each of fancy items. If he sold a jacket costing Rs 4400 for Rs 5060 at what price did he sell the shoes which was purchased for Rs 3420​

Answers

Answer:

RS 3933

Step-by-step explanation:

cost price =  RS4400

selling price =RS5060

now,

profit amount = selling price - cost price

                      =  RS5060 -RS4400

                       = RS660

profit %= profit amount / cost price * 100%

          = RS 660 / 4400 * 100

          = RS 15%

case II

profit % =15%

selling price = RS 3420

now,

profit amount = p% of cp

                      =15/ 100 *3420

                       =RS 513

selling price = cp +profit amount

                   = 3420+513

                    =RS 3933

Luke is designing a scale model of a clock tower. The design of the front of the tower is shown below.

A figure can be broken into a triangle and rectangle. The rectangle has a base of 200 millimeters and height of 50 millimeters. The triangle has a base of 50 millimeters and height of 100 millimeters.

What will be the area of the front face of his model?
2,500 square millimeters
10,000 square millimeters
12,500 square millimeters
15,000 square millimeters

Answers

The answer is 2,500. You must multiply both of the equations and add them together. The answer will be 2500.

Answer:

Answer:

Option B - 10,000 square millimeters

Step-by-step explanation:

From the image attached, we see that the dimensions of the front of the tower are;

Length; L = 200 mm

Width; w = 50 mm

Now, this front face takes the shape of a rectangle.

Area of rectangle = Length x width

Thus, plugging in the values of length and width, we will get;

Area of front face = 200 x 50

Area of front face = 10,000 square millimeters
