The probability of choosing one of us is      2 / 80 .

If that happens, then the probability of choosing
the other one is  1 / 79 .

The probability of both things happening is

        (2/80) x (1/79) =  1/3160  =  0.0003165... = 0.032... percent

In the graph below, find the coordinate of the image point. O is the origin and P is the point (4, 3). Ry and Rx are reflections
lidiya [134]

Answer:

We have been given the points origin and P (4,3)

We have reflection rule which is:

(x,y)\text{when reflected around y-axis}\Rightarrow(-x,y)

(x,y)\text{when reflected around x-axis}\Rightarrow(x,-y)

The given point x=4 and y=3 when reflected around y-axis the point becomes:

(-4,3)

The given point x=4 and y=3 when reflected around x-axis the point becomes:

(4,-3)

Taylor bought some jeans on sale. The number of jeans she bought is 1-fith the amount of money she spent. She bought 6 jeans. Fi
Rina8888 [55]

Answer:

30

Step-by-step explanation:

Let the amount of money Taylor spent = x

The number of jeans she bought is 1-fith the amount of money she spent. She bought 6 jeans.

Hence

1/5 × x = 6 jeans

x/5 = 6 jeans

Cross Multiply

x = 5 × 6 jeans

x = 30

The amount of money Taylor spent = 30

Hich value, when placed in the box, would result in a system of equations with infinitely many solutions?
Jobisdone [24]

The value placed in the box that makes the system of equation with infinitely many solution is 12.

<h3>How to solve an infinitely many solution equation?</h3>

An infinite solution has both sides equal. For example, 6x + 2y - 8 = 12x +4y - 16.  If we simplify the equation we will notice both sides are equal. This means the equation has an infinitely many solution.

Hence,

y = -2x + 4

Therefore,

6x + 3y = 12

divide the equation(ii) by 3

2x + y = 4

y = -2x + 4

Therefore, both equation are equal if the the box is filled with 12. This means for the value placed in the box that makes the system of equation with infinitely many solution is 12.
