one step equation Y/1.8=80 what’s the answer?? ( with steps )
Answer:
5) Y = 144
Step-by-step explanation:
[tex]\frac{Y}{1.8} = 80[/tex]
Bring 1.8 from the numerator to the denominator and change the sign from divide to multiply. Also, the 1.8 switches sides so the equation looks like:
Y = 80*1.8
Y = 144
Hence, Y is equal to 144.

The number of hours of TV watched each week by 8 seventh grade students is shown below.
11, 7, 9, 3, 3, 8, 10, 5
a. What is the mean number of hours of TV watching?
b. Mean absolute deviation =
c. Explain the meaning of the mean absolute deviation as it relates to the number of hours of TV watched.
Answer:
a) 7 hours ; b) 2.5 hours ; c) look at explanation
Step-by-step explanation:
a)
The mean of a data set is what we usually refer to as the average. To find the mean, you add up all of the values and divide by the number of values.
So, to find the mean, you need to add all of the values (the "value" is the the number hours each student watched)
11 + 7 + 9 + 3 + 3 + 8 + 10 + 5
= 56
You have 8 seventh-grade students, so your number of values is 8.
Dividing the sum of the values by the number of values would then be:
56 / 8
= 7
So, your mean is 7.
---------------------------------------
b)
(A deviation is how much a value differs from a certain value. If a person was supposed to be 5 feet tall, and they were 6 feet tall, they would deviate 1 foot from the value of 5. If the person was 4 feet tall, they would also have a deviation of 1 foot.)
The mean absolute deviation is complicated. You probably want to set up two columns (or at least this is how I was taught to do it), the first column being the value (represented by x in the mean absolute deviation formula), the second column being the difference between the mean of the data set and the value (the mean is represented as x with a line over it).
∑ is the sum of the values of the second column.
To find the mean (remember, mean = average) of the deviations, you are going to add all of the deviations together, and divide by your number of values.
I'll write out the second column (the difference from mean) below:
| x - [tex]\frac{}{x}[/tex] |
4
0
2
4
4
1
3
2
if you add all of these values up, you will get 20; ∑ = 20
[ | | means absolute value--essentially the distance of the value from 0, so a negative number is written as a positive numbers; |-3| = 3 ; |3| = 3 ]
Now you will find the mean of your deviations. The sum of all deviations (∑) = 20. The number of deviations/the number of values is 8.
So, the equation of 20 / 8 will give us the absolute mean deviation.
20/8 = Mean Absolute Deviation
Mean Absolute Deviation = 2.5
Your Mean Absolute Deviation is 2.5 [hours] .
------------------------------------------------
c)
Now you are being asked to interpret what this 2.5 indicates. It means that each student has, on average, a difference of 2.5 hours of TV watched from the mean. The Mean Absolute Deviation gives us a sense of how spread out the values of a data set are. We know that a mean absolute deviation of 0 would indicate that all values of the set are exactly identical. A mean deviation of 100 would indicate that all of the values are drastically different. So, a mean deviation of 2.5 indicates that all of the values (each student's watch hours) are fairly similar.
A health-food producer has 250 samples of a new snack to distribute in the mall. The producer has to keep at least 50 samples for display in the health-food store for the product launch. How long will the samples last if consumers are taking the samples at a rate of 25 every hour?
Answer:8 hours
Step-by-step explanation: There are 250 samples, but there are only actually 200, since 50 need to be on display. That means that they will last 200/25=8 hours.

Keiko surveyed people with cell phones.
Ages in years = a
Texts they send per day = t
He drew a best-fit line and determined its equation.
Evaluate how many texts a 15 year old would send each day according to Keiko's trend line equation.
Answer:
67.69
Step-by-step explanation:
You have your equation, t = -1.63 a + 92.14
a = age
a = 15
if you update your equation to fill in for a you get:
= -1.63 (15) + 92.14
-1.63 x 15 = -24.45
-24.45 + 92.14 = 67.69
67.69
Answer:
67.69
Step-by-step explanation:
You have your equation, t = -1.63 a + 92.14
a = age
a = 15
if you update your equation to fill in for a you get:
= -1.63 (15) + 92.14
-1.63 x 15 = -24.45
-24.45 + 92.14 = 67.69
67.69
Match these equation balancing steps with the description of what was done in each step.
Answer:
1. C 2. A 3. B
Step-by-step explanation:
Step 1: 12x - 6 = 10 divided by 2 is 6x - 3 = 5
Step 2: When you add three to the left side of the equation the negative 3and positive 3 cancel out and when you add three to the right side of the equation 5 + 3 = 8
Step 3: multiplying both sides by 1/6. 1/6 is the reciprocal of 6 so they cancel out. 1/6 times 8 is 8/6 which condenses to 4/3 in simple terms.
Type a digit that makes this statement true.
64,638,7
3 is divisible by 3.
Answer:
The digit that makes the statement true is 2...hope this helps:)
Answer:
The digit is two.
Step-by-step explanation:
It is very simple, to find if a number is divisible by 3 specifically, you need to add all the digits together. All the digits together added up to 37, which is not divisible by 3. But if you make the missing digit 2 then the digits add up to 39 which is divisible by 3.

Answer:
I think the volume is 31.5.
Step-by-step explanation:
Since you didn't include the original numbers for the base area, I just square rooted 9 because there's no other number other than 1 that you would multiply to get 9. Since volume is L*W*H I put 3 for the w and h (because 3*3 is 9) and then I multiplied 9 by 3.5 or 3 and 1/2 (the same thing) to get 31.5. So the volume is 31.5.
Answer:
I think the volume is 31.5.

I'm trying to find .580 (only the 80 is repeating in the decimal) rewritten as a simplified fraction. thanks in advance, this one is really tricking me up.
Answer:
Step-by-step explanation:
assuming its repeating as .580808080 etc your answer would be 115/198 :)
Answer:
115/198
Step-by-step explanation:
.580 = .5808080
.5808080 = x
5.808080 = 10x
58.08080 = 100x
580.8080 = 1000x
1000x - 10x = 575
575 = 990x
x = 575/990
Simplify:
575/990 = 115/198

what’s the answer to this?
X/3+1 = 6
Answer: x=15
Step-by-step explanation:
x/3+1= 6
Step 1: Subtract 1 from both sides (always do inverse operations with the number, not the x term(s))
x/3 + 1-1 = 6-1
x/3= 5
Step 2: Now we need to isolate x (get it on its own). To do this, we must move the 3 to the other side, which we will do by multiplying the 3 and the 5 (as since the 3 was used for divisision, its inverse operation is multiplication).
x/3 = 5
x = 5x3
x= 15
Step 3: Check by using PITA, or "Plugging In the Answers"
We came to the conclusion that x=15. Now, we can "plug in", or substitute the x in the equation for 15:
x/3 + 1= 6
15/3 + 1= 6
5+ 1= 6
6=6
Correct ✔️
Answer:
X = 24
Step-by-step explanation:
3 + 1 = 4
X/4 = 6
Multiply both sides by 4
X = 24

Triangle PQR is transformed to triangle P'Q'R'. Triangle PQR has vertices P(3, −6), Q(0, 9), and R(−3, 0). Triangle P'Q'R' has vertices P'(1, −2), Q'(0, 3), and R'(−1, 0).
Plot triangles PQR and P'Q'R' on your own coordinate grid.
Part A: What is the scale factor of the dilation that transforms triangle PQR to triangle P'Q'R'? Explain your answer.
Part B: Write the coordinates of triangle P"Q"R" obtained after P'Q'R' is reflected about the y-axis.
Part C: Are the two triangles PQR and P''Q''R'' congruent? Explain your answer.
Answer:
Part A :
The scale factor of the dilation that transforms triangle PQR to triangle P'Q'R' is divided by 3.
Part B :
P"(-1,2), Q"(0,3), R"(1,0)
Part C :
Triangle PQR and P"Q"R" are not congruent because congruent means equal and similar but triangle PQR and P"Q"R" are proportional because they are rational to each other but do not have the same measures of sides but the angles are congruent.
This is the graphing of the triangle.
