Answer:

(45,60)

Step-by-step explanation:

in a parallelogram, opposite angles are equal measure

2x-10 = y + 20

angles that lie on the same line add up to 180, since alternate angles of parallel lines and a transversal are equivalent

2x + 10 + 2x - 10 = 180

solving the equation with only Xs

4x = 180

x = 180/4 = 45

plug x = 45 into x and y equation

90-10 = y+ 20

80 = y + 20

y = 80-20 = 60

Answer:

3x-y=1 is in the form Ax+By=c

where A=3, B=-1, C=1

Step-by-step explanation:

we have to convert the equation y-5=3(x-2) to the form Ax + By = C.

the equation y-5=3(x-2) is in the form y-y_{1} =m(x-x_{1} )

which is the point slope form of a straight line in cartesian coordinate.

where m is the slope of the line and x_{1} ,y_{1} is the point through which the line is passing through.

therefore y-5=3(x-2) becomes y-5  = 3x-6

y-5+6=3x

y+1=3x

3x-y=1

this equation is in the form Ax+By=c

therefore comparing these two equations we get

A=3, B=-1, C=1

A sales analyst listed the probabilities of profits and losses in dollars for a certain company. Find the mean for the probabili
kakasveta [241]

Answer: The mean for the probability distribution will be 69.25.

Explanation:

Since we given that

At\ x_1= -500 ,P(x) = 0.076\\

At\ x_2= -250,P(x)= 0.191\\

At\ x_3=0, P(x)= 0.265\\

At\ x_4=250 , P(x)= 0.316\\

At\ x_5=500 , P(x)= 0.152\\

As we know the formula for expectation of x i.e. known as mean for the probability distribution,

E(x)=x\sum_{1}^{5} P(x)

So, we  apply this formula in our case,

-500\times 0.076+(-250)\times 0.191+0\times 0.265+250\times 0.316+500\times 0.512=69.25

\mu = 69.25

Hence, the mean for the probability distribution will be 69.25.
