Answer:
A
Step-by-step explanation:
6 friends
Mean - 10
Median - 9.5
Range - 14
3 friends watched 12, 13, and 18 movies.
Let's find the sum, this will help us find the total number of movies the other 3 friends watched.
12 + 13 + 18 = 43
The mean is all their movies added toether, divided by the number of friends.
m = number of movies the other friends watched.
(43 + m) / 6 = 10 Multiply each side by 6
43 + m = 10 * 6
43 + m = 60 Subtract 43 from each side
m = 60 - 43
m = 17
So we know the total movies the other friends watched is 3.
A. 4+6+7 = 17
B. 4+4+7 = 15
C. 5+8+9 = 22
D. 2+3+5 = 10
We know the answer is A.
We can check it by looking at the Median, the median is the middle number, if there are an even number of samples, you add the 2 middle numbers together and divide by 2.
4, 6, 7, 12, 13, 18
So 7+12 = 19
19/2 = 9.5
So we know for sure A is correct!

What are ratio and proportion?A ratio is a comparison between two similar quantities in simplest form.
Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.
In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.
Given, Lisa and her brother are saving money to go on a trip. For every $2 Lisa saves, her brother saves $5.
Therefore, The ratio of saving money for Lisa and her brother is,
Lisa : Her brother = 5 : 2.

Answer: can it be a fraction?
Step-by-step explanation:
Answer: y = 4/3 + 1/4x
Step-by-step explanation: 6y - 1.5x = 8
Add 1.5x to get y alone, 6y = 8 + 1.5x
Divide everything by 6, y = 8/6 + 1.5x/6

What is the slope of the line that passes through the points (-3, -3)(−3,−3) and (-18, -23) ?(−18,−23)? Write your answer in the simplest form.
Answer:
Let's see what to do buddy...
Step-by-step explanation:
_________________________________
Step (1)
To find the slope of linear functions using two points, we have the following equation :
[tex]slope = \frac{y(b) - y(a)}{ x(b) - x(a) } \\ [/tex]
Where a and b are two point of the function.
_________________________________
Step (2)
Well now I want to choose a name for the given points :
a = ( -3 , -3 ) ••••••••• b = ( -18 , -23 )
_________________________________
Step (3)
It's time to put the the coordinates in the above equation :
[tex]slope = \frac{ - 23 - ( - 3)}{ - 18 - ( - 3)} \\ [/tex]
[tex]slope = \frac{ - 23 + 3}{ - 18 + 3 } \\ [/tex]
[tex]slope = \frac{ - 20}{ - 15} \\ [/tex]
Negatives simplified :
[tex]slope = \frac{20}{15} \\ [/tex]
The face and denominator are reduced to five :
[tex]slope = \frac{4}{3} \\ [/tex]
_________________________________
And we're done.

the mean mass of 6 boxes is 45kg. one of the boxes with a mass of 50kg is removed. calculate the new mean mass of the remaining boxes
Answer: 6 boxes. average 45 each.
Step-by-step explanation:
The mean of a dataset if the average of the dataset.
The new mean mass of the remaining boxes is 44 kg
From the question, we have:
[tex]\mathbf{\bar x = 45}[/tex] --- mean of 6 boxes
The mean of a dataset is:
[tex]\mathbf{\bar x = \frac{\sum x}{n}}[/tex]
So, we have:
[tex]\mathbf{45 = \frac{\sum x}{6}}[/tex]
Multiply by 6
[tex]\mathbf{45 \times 6= \sum x}[/tex]
[tex]\mathbf{\sum x = 270}[/tex]
One of the boxes is 50 kg.
So, the mass of the remaining boxes is:
[tex]\mathbf{Mass = 270 - 50}[/tex]
[tex]\mathbf{Mass = 220}[/tex]
The mean of the remaining boxes is:
[tex]\mathbf{\bar x = \frac{\sum x}{n}}[/tex]
[tex]\mathbf{\bar x = \frac{220}{5}}[/tex]
[tex]\mathbf{\bar x = 44}[/tex]
Hence, the new mean mass of the remaining boxes is 44 kg
