Answer: I think 8?
Step-by-step explanation:
You might be adding the 6 so therefore maybe you do 6+2= 8 if the median was eqaul to 6.
If this isnt right, I'm sorry!
Answer: 1
The set is:
6 1 5 4 8 7 2 1 2 2
First: We get the median of the original set. To do this we change it from highest to lowest.
1 1 2 2 2 4 5 6 7 8
Then we take the middle number of this set which is the median
2 and 4 are the middle so the median is 3
The median of set 1 is 3
Second: We get the median of the set but with another 6 added
1 1 2 2 2 4 5 6 6 7 8
Take the middle number of this set which is the median
4
The median of set 2 is 4
From this we know the median increases by 1 if the number 6 is added!
70% of s is 455, what is s?
Answer:
650
Step-by-step explanation:
[tex]7/10s = 455\\7s = 4550\\s = 650[/tex]
Answer:
650
Step-by-step explanation:
[tex]\frac{70}{100} =\frac{455}{y}[/tex]
First, to answer this you cross multiply. This means:
[tex]45,500=70y[/tex]
Now you divide each side by 70, and you get 650
You're a quality control manager in a fruit juice company. You want to choose
a sample size for a quality check on the cans used to package the juice. From
a batch of 30,000 cans, you want a sample size that will allow you to closely
approximate the population parameters for the entire batch. Which sample
size will most likely produce the least variability among different samples?
Answer:
246.
Step-by-step explanation:
a) The 95% confidence level two-tail confidence interval for the mean value of the key index of this batch is between 98.22 and 99.78
b) The minimum sample size to achieve this is 246.
Step-by-step explanation:
We have that to find our level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of .
So it is z with a pvalue of , so
Now, find the margin of error M as such
In which is the standard deviation of the population(square root of the variance) and n is the size of the sample. So in this question,
The lower end of the interval is the sample mean subtracted by M. So it is 99 - 0.78 = 98.22
The upper end of the interval is the sample mean added to M. So it is 99 + 0.78 = 99.78.
a) The 95% confidence level two-tail confidence interval for the mean value of the key index of this batch is between 98.22 and 99.78
(b) (5 points) If we want the sampling error to be no greater than 0.5, what is the minimum sample size to achieve this based on the same confidence level with part (a)
We need a sample size of n
n is found when
Then
Rounding up
The minimum sample size to achieve this is 246.

You want to create a scale model for a building that will be 120feet tall and 40 feet wide. If you make the model 6 feet tall, how wide should it be?
Given:
Length of the building = 120 feet
Width of the building = 40 feet
Length of the model = 6 feet
To find:
Width of the model.
Solution:
The scale model similar to the original figure and the corresponding sides of the similar figures are proportional.
Let x be the width of the building.
[tex]\dfrac{\text{Length of the building}}{\text{Length of the model}}=\dfrac{\text{Width of the building}}{\text{Width of the model}}[/tex]
[tex]\dfrac{120}{6}=\dfrac{40}{x}[/tex]
[tex]20=\dfrac{40}{x}[/tex]
[tex]x=\dfrac{40}{20}[/tex]
[tex]x=2[/tex]
Therefore, the width of the model is 2 feet.
Mr. K was able to spot quite a few window washers on the skyscrapers there. He asked them how long it took to wash windows on such a building. They said that each person could wash 50 windows in 1 hour.
(How long would it take the 3 workers to wash all 1000 windows on one of the skyscrapers?)
Answer:
6.7 hours
Step-by-step explanation:
If one can do 50 then three can do 150.
So 1000÷150=6.66666666666

On the map, Winton ,California is located at(“ (2,10.5) in Lake Tahoe is located at (14,16). Each unit on the map equals 16.5 miles what is the approximate distance between the cities round to the nearest mile.
Answer:
The distance between the two
points on the map
is 225 units
Step-by-step explanation:
Firstly, we need to calculate the distance in units between the two locations on the map
What we have to use here is the distance formula
Mathematically, we have this as;
D = √(x2-x1)^2 + (y2-y1)^2
(x1,y1) = (2,10.5)
(x2,y2) = (14,16)
we have the distance as follows;
D = √(14-2)^2 + (16-10.5)^2
D = √(12^2 + 6.5^2)
D = √(186.25)
D = 13.65 units
now, from the question, 1 unit on the map represents a distance of 16.5 miles
thus, a distance of 13.65 units will be;
16.5 * 13.65 = 225.225
= 225 units
Which expressions have a value that is 8 times as much as the sum of 10 and 9? Select the correct answers.
0- 8 x (10 + 9)
1 - 8 x 10 + 9
2- 10 + 9 x 8
3- (10 + 9) x 8
4- (10 x 8) + 9
Answer:
3
Step-by-step explanation:
(10+9) = 19
19×8 =152
when you divide 152by8 you still get 19 which is the sum of 10+9

PLEASE HELP ME A soccer field is bordered on three sides by a parking lot of width x. The total length of the field and parking lot is 300 m, and the total width is 200 m.
The area of the field is 30.000 m². How wide is the parking lot?
Answer:
Step-by-step explanation:
Assuming the parking lot is along both widths of the field and only once along the length:
the length is (300 - 2x)
the width is (200 -x)
the area is (300-2x)(200-x) = 30000
60000 -300x - 400x +2x^2 = 30000
2x^2 -700x + 30000 = 0
x^2 - 350x + 15000 = 0
(x - 300 )(x - 50 ) = 0
x = 300 or x=50
x=300 results in negative measures.
the parking lot is x=50 wide
the length of the field is 200, the width of the field is 150

Kensington charges $20 per hour, h, teaching music lessons. Last year, Kensington earned $37,705, including tips, t. Given this information, which of the following equations can be used
the amount Kensington made in tips last year?
Of=37705 + 20h
O t = 37705 - 20h
Ot=37705h + 20
O = 37705h - 20
Answer:B-t=37705-20h
Step-by-step explanation:The answer is B because you need to get rid of all of the money she made working so you subtract 20 by how ever many hours she has worked
Answer:
Second option : t = 37705 - 20h
