△RST is mapped to △R′S′T′ using the rule (x, y)→(x, −y) followed by (x, y)→(3x, 3y) .
Which statement correctly describes the relationship between △RST and △R′S′T′ ?
△RST is congruent to △R′S′T′ because the rules represent a reflection followed by a rotation, which is a sequence of rigid motions.
△RST is congruent to △R′S′T′ because the rules represent a reflection followed by a translation, which is a sequence of rigid motions.
△RST is congruent to △R′S′T′ because the rules represent a rotation followed by a translation, which is a sequence of rigid motions.
△RST is not congruent to △R′S′T′ because the rules do not represent a sequence of rigid motions.
By the way, this question DOES NOT include a picture, so don't ask please.
Answer:
△RST is not congruent to △R′S′T′ because the rules do not represent a sequence of rigid motions.

Is the expression 3x+2x−4 in simplest form
3x+2x-4 is not in simplest form.
What is Expression?An Expression is Combination of variables, numbers and operators.
The given expression is three x plus two x minus 4
i.e 3x+2x-4
It is not in simplest form because we have to add like terms.
In the above expression we have two terms of same variable.
We have to add 3x and 2x which gives 5x.
So 5x-4 is the simplest form.
Hence 3x+2x-4 is not in simplest form.

A carpenter has a 6-foot long board. He wants to cut the board into pieces that are 4/5 foot long. How many pieces of length 4/5 foot can the carpenter cut from the board? What length of the original board will be left after the carpenter has cut all the pieces that are 4/5 foot long?
Answer:
Number of pieces=7
Length of board remaining=[tex]\frac{2}{5}[/tex]
Step-by-step explanation:
We are given that a carpenter has board of length=6 foot
Length of each piece of board=[tex]\frac{4}{5}[/tex] foot
We have to find the number pieces of given length of piece can be made from given board.
In order to find the number of pieces we will divide the total length of board by the length of each piece.
Therefore, number of pieces =[tex]\frac{6}{\frac{4}{5}}[/tex]
Number of pieces=[tex]7\frac{1}{2}[/tex]
Length of each piece =[tex]\frac{4}{5}[/tex]
Therefore, number of pieces=7
Length used in 7 pieces =[tex]7\times\frac{4}{5}=\frac{28}{5}[/tex]
Length of board remaining=[tex]6-\frac{28}{5}=\frac{2}{5}[/tex]

The time at which the mailman delivers the mail to ace bike shop follows a normal distribution with mean 2:00 pm and standard deviation of 15 minutes.
There are three questions related to this problem.
First, the probability of the mail will arrive after 2:30 PM
Find the z-score of 2:30 which is 30 minutes after 2:00.
z(2:30) = (2:30 – 2:00)/15 = -30/15 = -2
P(x < 2:30) = P(z<-2) = 0.0228
Second, the probability of the mail will arrive at 1:36 PM
Find the z-score of 1:36 which is 24 minutes before 2:00.
z(1:36) = (1:36 – 2:00)/15 = -24/15 = -1.6
P(x < 1:36) = P(z<-1.6) = 0.0548
Lastly, the probability of the mail will arrive between 1:48 PM and 2:09 PM
Find the z-score of 1:46 and 2:09 PM which will result to a z value of 0.034599
P(1:48 < x < 2:09) = P(z<0.034599) = 0.5138

A television game has 6 shows doors, of which the contests must pick 2. behind two of the doors are expensive cars, and behind the other 4 doors are consolation prizes. Find the probability that the contestant wins exactly 1 car? no car? or atleast one car?
Answer:
In this question, there are 4 consolation door and 2 car doors of total 6 doors. That means for the first door the chance to get consolation is 4/6 and car is 2/6. In second door, only 5 remains so the chance to get consolation is either 4/5 (if 1st door car) or 3/5(if 1st door consolation)
Win 1 car condition:
1. 1st door car, 2nd door consolation = 2/6 * 4/5 =8/30
2. 1st door consolation, 2nd door car= 4/6 * 2/5 = 8/30
8/30+8/30= 16/30
No car condition
1. 1st door consolation, 2nd door consolation= 4/6 * 3/5= 12/30
At least one car condition
1. 1st door car, 2nd door car = 2/6 * 1/5 =2/30
2. 1st door car, 2nd door consolation = 2/6 * 4/5 =8/30
3. 1st door consolation, 2nd door car= 4/6 * 2/5 = 8/30
2/30 + 8/30 + 8/30= 18/30
