i have a test tomorrow and i forgot this but how do you do something like this:
-(-14⅞)-15+(-⅚)-14⅞
Answer:
-15 5/6
Step-by-step explanation:
Combine the given terms (through addition and subtraction).
14 7/8 - 15 - 5/6 - 14 7/8
Identify the LCD: It is 24
Therefore we have:
14 21/24 - 15 - 20/24 - 14 21/24
Combining the whole numbers, we get
14 - 15 - 14, or -15
and combining the fractions, we get
21 - 20 - 21
----------------- = -20/24
24
and so we have -15 - 20/24, or -15 - 5/6, or -15 5/6
Forrest has determined that if he gets to the bus stop at 7:30 am, there is a 0.15 probability that he misses the bus. If
he arrives at the bus stop three consecutive days at 7:30, what is the approximate probability that he catches the bus all
three days?
Answer: 0.614
Step-by-step explanation:
First find the probability that he catches the bus in a day.
Probability of catching bus once = 1 - Probability of missing bus
= 1 - 0.15
= 0.85
If he arrives on 3 consecutive days at 7:30 am, the probability he will catch the bus is:
= (P | Day 1) * (P | Day 2) * (P | Day 3)
= 0.85 * 0.85 * 0.85
= 0.614
The approximate probability that he catches the bus all three days is 0.614.
Given that,
Forrest has determined that if he gets to the bus stop at 7:30 am, there is a 0.15 probability that he misses the bus.
If he arrives at the bus stop three consecutive days at 7:30,
We have to determine,
What is the approximate probability that he catches the bus all three days.
According to the question,
The probability that he catches the bus in a day.
Probability of catching bus once = 1 - Probability of missing bus,
= 1 - 0.15
= 0.85
If he arrives on 3 consecutive days at 7:30 am,
Then, the probability he will catch the bus is:
= (P | Day 1) × (P | Day 2) × (P | Day 3)
= 0.85 × 0.85 × 0.85
= 0.614
Hence, The approximate probability that he catches the bus all three days is 0.614.

Answer:
y +2 = -1/2(x -7)
Step-by-step explanation:
The line PQ has a rise of 6 units for a run of 3 units, so its slope is ...
m = rise/run = 6/3 = 2
A line perpendicular to PQ will have a slope that is the opposite reciprocal of that, so ...
-1/m = -1/2
We have the slope of the desired line, and a point it needs to pass through, so we can use the point-slope form of the equation of a line.
y -k = m(x -h) . . . . . . line with slope m through point (h, k)
An equation for the desired line is ...
y +2 = -1/2(x -7)
__
This can be rearranged to other forms.
y = -1/2x +3/2 . . . . . slope-intercept form
x +2y = 3 . . . . . . . . . standard form

Solve for n.
n+ 1 = 4(n-8)
Answer:
11
Step-by-step explanation:
n+1=4(n-8)
n+1=4n-32
4n-n-32=1
3n-32=1
3n=1+32
3n=33
n=33/3
n=11
Answer:
n = 11
Step-by-step explanation:
The equation is n+1=4(n-8). This is much easier to solve after expanding, which makes n+1=4n-32. Then, add 33 to each side to make n+33=4n. Next, take away n from each side, to get 33=3n. You want to find n, so divide each side by 3. This means you end up with 11=n.

Four people—Rob, Sonja, Jack, and Ang—enter their names into a drawing. The winner receives either a t-shirt or a mug, and which prize they receive is randomly selected.
What is the probability that either Ang wins and is given a mug, or Jack wins (and is given either prize)? Give the answer as a percent.
Answer: 50%
Step-by-step explanation: Good luck! :D
Answer:
The probability is 37.5%
Step-by-step explanation:
There are eight total outcomes, but we only need to focus on three. Ang winning a mug and Jack winning either a t-shirt or a mug, that makes three. Write that as a fraction: 3/8, and then divide. 3 divided by 8 gives us 0.375. But we need a percent so multiply that by 100, that now gives us 37.5.
So, the probability that either Ang wins and is given a mug, or Jack wins is 37.5%. If it makes you feel more confident in this, I put the same exact answer for my assessment and I got it correct.

A.) Write a direct variation equation to represent the cost.
B.) Using the equation found in part a, how much would it cost a hotel to have 150 rooms cleaned
Answer:
Step-by-step explanation:
The cost that a carpet can cleaning company charges is directly proportional to the number of rooms cleaned. The cost to clean 50 rooms is $1,100.
A.) Write a direct variation equation to represent the cost.
Cost ∝ Number of room
C ∝ N
C = kN
k = Constant of Proportionality
k = C/N
k = 1100/50
k = 220
B.) Using the equation found in part a, how much would it cost a hotel to have 150 rooms cleaned
c = 220 × 150
c = $33000
Cost to clean 150 rooms = $33,000

Please help the question is in the picture
Answer:
- True
- True
- False
- True
Step-by-step explanation:
- Subtracting the equation will get rid of y variable therefore it's a correct and logical first step to solve the system
- The solution is indeed (-3, -3) as if we substitute these values in both equation, the equation will be correct and valid.
[tex]-2(-3)+(-3)=3[/tex] (Correct)
[tex]3(-3)+2(-3)=-15[/tex] (Correct)
- We have already determined the logical first step. Multiply by -2 will not get rid of any of the variables. Therefore, this is false.
- The solution can be written as one value since x = y = -3. Therefore, this statement is true.
