Answer:

The union of two event

Step-by-step explanation:

Addition law of probability define that probability of two event is total sum of probability of any event subtract the probability of both events

There are two rules in addition law:

Addition law 1 - when both event are mutually exclusive, then probability of either event is the sum of each event probability.

P( A or B) = P(A) +P(B)

Addition law 2 - when both events are non mutually exclusive then there in addition to the individual probability there is some overlap .

P( A or B) = P(A) +P(B) - P(A and B)

Order from least to greatest 2.8%, 7/40, 1/50, 0.044

lord [1]

Answer:

1/50 < 2.8% < 0.044 < 7/40

Step-by-step explanation:

2.8%, 7/40, 1/50, 0.044

2.8% = 0.028 = 28/1000
7/40 = 0.175 = 175/1000
1/50 = 0.020 = 20/1000
0.044 = 44/1000

Ordering in ascending order

20/1000 < 28/1000 < 44/1000 < 175/1000

Same order in original numbers

1/50 < 2.8% < 0.044 < 7/40

We know that

in the figure equivalent ratios are
BS/BC
and
AR/AC

therefore

AR/RC is not equivalent

the answer is
AR/RC

Which sequence of transformations produces R'S'T' from RST? On a coordinate plane, triangle R S T has points (0, 0), (negative 2

arsen [322]

Answer:

Step-by-step explanation:

Given is a triangle RST and another triangle R'S'T' tranformed from RST

Vertices of RST are (0, 0), (negative 2, 3), (negative 3, 1).

Vertices of R'S'T' are (2, 0), (0, negative 3), (negative 1, negative 1).

Comparing the corresponding vertices we find that x coordinate increased by 2 while y coordinate got the different sign.

This indicates that there is both reflection and transformation horizontally to the right by 2 units

So first shifted right by 2 units so that vertices became

(2,0) (0,3) (-1,1)

Now reflected on the line y=0 i.e. x axis

New vertices are

(2,0) (0,-3) (-1,-1)
