Answer:
x = -2/7 or
x = 6/7
Step-by-step explanation:
|7x-2| + 3 = -1 subtract 3 from both sides
|7x-2| = -4 now there are two probabilities
7x-2 = -4 or
7x-2 = 4 if first probability the value of x would be:
7x-2 = -4 add 2 to both sides
7x = -2 divide both sides by 7
x = -2/7 for the second probability the value of x would be:
7x-2 = 4 add 2 to both sides
7x = 6 divide both sides by 7
x = 6/7

Four speed skaters, Marco, Naim, Oliver, and Pedro, compete in a relay race where they all agree that Naim will be the last skater. Then, they try to decide whether or not Oliver should be the first skater in the race.
Which subset, A, of the sample space shows the complement of the event in which Oliver is the first skater in the race?
A = {MOPN, PMON}
A = {OPMN, OMPN}
A = {MOPN, MPON, OPMN, POMN}
A = {MOPN, MPON, PMON, POMN}
Answer:
A = {OPMN, OMPN}
Step-by-step explanation:
If Olivers first and Naims last that's the only one that fits
Hope this helps, please leave any questions or concerns in the comments. Thanks
A = {MOPN, PMON} is the subset of the sample space shows the complement of the event in which Oliver is the first skater in the race
What is Probability?It is a branch of mathematics that deals with the occurrence of a random event.
The sample space of the relay race is the set of all possible arrangements of the four skaters, which can be represented by the permutations of the set {M, N, O, P}.
Since Naim is the last skater, there are 3! = 6 possible arrangements of the other skaters in front of him.
The event in which Oliver is the first skater in the race can be represented by the set {OMPN, OPNM, ONPM, ONMP}, which contains 4 possible arrangements.
The complement of this event is the set of all arrangements where Oliver is not the first skater, which can be represented by the set A.
Since there are 6 possible arrangements and 4 of them have Oliver in the first position, there are 6 - 4 = 2 arrangements in A.
A = {MOPN, PMON} is the complement
Hence, A = {MOPN, PMON} is the subset, A, of the sample space shows the complement of the event in which Oliver is the first skater in the race

Sandi got 1/1/4 pounds of gummy worms if she left the store with 3 pounds of gunmys worms and skittles ,how many pounds of skittles did she get
Answer:
1 3/4 lbs of skittles
Step-by-step explanation:
Easy way: 3lbs - 1 1/4lbs = 1 3/4lbs
Complex way:
(I'm assuming "1/1/4" means "1 1/4")
This is simply ~Subtraction~
The total is 3lbs(t) and 1 1/4 of that 3lbs is gummy worms(g). What is left of the 3lbs is skittles(s).
So we need to know what added to 1 1/4 equals 3.
Equation: t= 1 1/4 + s
Equation: t= 1 1/4 + s
We can replace (t) with 3 because we know this variable.
1. 3= 1 1/4 + s
To isolate the variable (s) we need to subtract 1 1/4 on both sides of the equation
2. 3(- 1 1/4)= 1 1/4(- 1 1/4) + s
The right side cancels out = 0 and the left = 1 3/4
3. 1 3/4= s
Flip it around for the traditional view
4. s = 1 3/4
In word form: Skittles equal 1 3/4 (don't forget to add lbs or pounds back into the final answer)

Find length
__
AB
A:-6
B: 8
To find the distance between those two points you would need to
do, -6 - (8), which is -14, and than take away the minus sign, and the length of AB is 14 units.
Answer:
14 = AB
Step-by-step explanation:
When finding length, absolute value is the way to go! So if A is -6 and b is 8, then we need to find the distance between them. You can physically count on a number line like I see you did, which would be -5,-4,-3,-2,-1,0,1,2,3,4,5,6,7,8=14 numbers
or you can set up the expression---
| -6-8 |
which equals
| -14 |
or
14
because 14 is the same as | -14 |

A car is traveling 90 miles per hour. How fast is it traveling in miles per minute?
Answer: 1.5 miles per minute
Step-by-step explanation:
The ratio for the hours is 90 Miles : 60 Minutes
Since 1 hour is 60 minutes, then 1 minute is 1/60 of a hour.
So, 1/60 will be the constant.

These circles are:
A. concentric
B. none of these
C. tangent
D. congruent
These circles are tangent .
What is tangent of two circles?Two circles are tangent to each other if they have only one common point. Two circles that have two common points are said to intersect each other. Two circles can be externally tangent if the circles are situated outside one another and internally tangent if one of them is situated inside the other.
According to the question
These circles are :
A > Concentric
This option is incorrect because circle are concentric if and only if they have common center .
B> none of these
This option is incorrect .
C > Tangent
This option is correct as Two circles are tangent to each other if they have only one common point and in the figure there is only one common point between both circles .
D> Congruent
This option is incorrect as this two circles have different size but in congruent both circle should be same size which is not possible here.
Hence, These circles are tangent .
