Answer:

<h2>6 \frac{3}{10}</h2>

Step-by-step explanation:

4 \frac{1}{5}  \div  \frac{2}{3}  =  \frac{21}{5}  \div  \frac{2}{3}  =  \frac{21}{5}  \times  \frac{3}{2 }  \\  \\  =  \frac{63}{10}  = 6 \frac{3}{10}

Please see the answer in the picture attached below.

" From Step 1: We find that Angle N1 equals to 75 gradius => Answers A and C wrong. Answers B and D are left.

" From Step 4: We find that Angle N2 equals to 129 gradius => Answer B is true.

You don't need to find the exact value of the angle N3 in oder to choose the right answers from A,B,C,D.

Hope this answer can help you. Have a nice day!

Can anyone please help me in this

These problems are called systems of equations. Basically you have two linear equations and you need to find the values for x and y. In other words, all these equation are lines and our answer will be the exact point that the pair of lines intersect. For example, if we get x=1 and y=2 the lines will intersect at point (1,2). Now that you have some background knowledge here comes the tricks and tactics kid.

We know that we can solve one variable equation easily. For example...

x+1=2

x=1 obviously

Cause we have two variables x and y it is not possible to find a solution. For example, in the equation x+y=10, x=1 when y=9 and x=2 when y=8. There is not correct answer.

So what can we do? We have to make a two variable equation into a one variable equation.

There are two ways to do this: substitution and elimination. I will create a sample problem and then solve it using both methods.

x+y=2

2y-y=1

3)  

-3x-5y=-7 -----> -12x-20y=-28

-4x-3y=-2 ------> -12x-9y=-6

 -12x-20y=-28

-(-12x-9y=-6)

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

-11y=-22

y=2

-3x-5(2)=-7

-3x=3

x=-1

4) 8x+4y=12 ---> 24x+12y=36

7x+3y=10 ---> 28x+12y=40

 28x+12y=40

-(24x+12y=36)

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

4x=4

x=1

8(1)+4y=12

4y=4

y=1

5) 4x+3y=-7

-2x-5y=7 ----> -4x-10y=14

    4x+3y=-7

+(-4x-10y=14)

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

-7y=7

y=-1

4x+3(-1)=-7

4x=-4

x=-1

6) 8x-3y=-9 ---> 32x-12y=-36

5x+4y=12 ---> 15x+12y=36

 32x-12y=-36

+(15x+12y=36)

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

47x=0

x=0

8(0)-3y=-9

-3y=-9

y=3

7)-3x+5y=-2

2x-2y=1 ---> x-y=1/2 ----> x=y+1/2

-3(y+1/2)+5y=-2

-3y-1.5+5y=-2

2y=-0.5

y=0.25

2x-2(0.25)=1

2x=1.5

x=0.75

How do you use the order of operations to evaluate expressions with exponents?
IgorLugansk [536]
Using BEDMAS, it would be brackets first, so anything Inside a set of brackets would be solved first, and would follow the same rule. Once the brackets have been solved, next would be the exponents. Since your brackets have been solved you can expand with the exponents. After exponents, would be anything that has to be divided or multiplied. These two operations are interchangeable based on what is more convenient or beneficial to do first. And lastly, addition and subtraction, which once again are interchangeable operations

In a class of 25 students, 15 of them have a driver's license. If ten students are randomly selected, what is the expected numbe
const2013 [10]

Answer:

<em>Expected number of students  would have a driver's license = 6</em>

Step-by-step explanation:

<u><em>Explanation</em></u>:-

Given data In a class of 25 students, 15 of them have a driver's license

The sample proportion

                                p = \frac{x}{n} = \frac{15}{25} = 0.6

Let 'X' be the binomial distribution

Given sample size 'n' = 10

<em>mean of the binomial distribution or expected number of students  would have a driver's license</em>

                                 μ = n p

                                    = 10 × 0.6

                                   = 6

<u><em>Conclusion</em></u>:-

<em>Expected number of students  would have a driver's license = 6</em>
