(1.5,0) ? I'm not sure...

Answer:

The correct option is 2.

Step-by-step explanation:

The given system of equations is

y=\frac{1}{4}x-2              .... (1)

y=-2x+3                  .... (2)

Subtract equation (2) from equation (1), to eliminate y.

y-y=\frac{1}{4}x-2-(-2x+3)

0=\frac{1}{4}x-2+2x-3

On combining like terms we get

0=\frac{9}{4}x-5

Add 5 on both sides.

5=\frac{9}{4}x

Multiply both sides by 4.

20=9x

Divide both sides by 9.

\frac{20}{9}=x

The value of x is \frac{20}{9}.

Substitute x=\frac{20}{9} in equation (2).

y=-2(\frac{20}{9})+3=-\frac{13}{9}

The solution of given system of equation is

(\frac{20}{9},-\frac{13}{9})=(2.22...,-1.44...)\approx (2.2,-1.4)

Therefore the correct option is 2.

An electric company has to track on-time payments and late payments for each customer monthly. It is impossible for a customer t
OLga [1]

Answer:

The  probability that a customer pays late each month is    P(B)  =  0.27

Step-by-step explanation:

Let     P( A ) be the probability that the customer pays on time and the value is  0.55

Let  P( B )  be the  probability that a customer pays late each month

So

  The probability that a customer pays late or on-time each month  is  P(A u B) and  the value is  0.82

The probability that a customer pays on-time and late each month is  P(A n B) and  the value is  zero ( 0 ) given that it is impossible

   Now The probability that a customer pays late or on-time each month  is mathematically represented as

      P(A u B)  =  P(A) +  P(B)  -   P(A n B)

=>     0.82  =  0.55 + P( B ) -   0

=>    P(B)  =  0.27

There is a cereal box and the dimensions are 10 inches tall, 3 inches wide and 7 inches long. If you were to fill the box with c
JulsSmile [24]

Answer:

$6.30

Step-by-step explanation:

First, get the volume of the cereal box with the equation V = lwh.

V = 7(3)(10) = 210 cubic inches

Since it costs $.03 per cubic inch, multiply this cost by the volume to get the total cost to fill the box.

.03(210) = $6.30
