what is the mean of 8,445,276,1198
Answer:
1028.5 is the mean
Answer:
481.75
Step-by-step explanation:
To find the mean add up all the numbers in the data set :
8 + 445 + 276 + 1198 = 1927
divide the numbers by how many numbers are in the data set :
1927 ÷ 4 = 481.75
Therefore, the mean in the data set 481.75

Step-by-step explanation:
The distance from Detroit, MI to Paris, France is approximately 3930 mi. Flying from Detroit to Paris takes 8 hr with the jet stream. The return flight takes 8.3 hr since the plane is flying against the jet stream.
a. The speed of the plane in still air, rounded to the nearest whole number, is
b. The speed of the jet stream, rounded to the nearest whole number, is
Answer:
a. 482
b. 9.0
Step-by-step explanation:
The speed of the plane in still air is approx 482 miles per hour(mph). The speed of the jet stream, rounded to the nearest whole number, is 9 mph
How does air stream affects speed of flight?Flight speed in air stream = Flight speed in still air + effect of air stream
If the flight is going opposit, then:
Flight speed in air stream = Flight speed in still air - speed of air streamIf the flight is going along with flight, then:
Flight speed in air stream = Flight speed in still air + speed of air streamFor this case, we're specified that:
Distance from Detroid to Paris is approx 3930 milesTime it takes by flight along the air stream = 8 hoursTime it takes by flight against the air stream = 8.3 hoursSpeed of flight along the stream is:
[tex]S = \dfrac{\delta D}{\delta T} = \dfrac{3930}{8} = 491.25 \: \rm mph[/tex]
Speed of flight against the stream is:
[tex]S = \dfrac{\delta D}{\delta T} = \dfrac{3930}{8.3} \approx 473.49 \: \rm mph[/tex]
Let the speed of air stream be y, and that of the flight in still air be x miles per hour, then we get:
Along air stream:
[tex]x + y =491.25\\[/tex] (in miles per hour)
and Against the stream:
[tex]x - y =473.49\\[/tex] (in miles per hour)
Adding both the equations side by side, we get:
[tex]2x + y - y = 491.25 + 473.49\\\\x = \dfrac{964.74}{2} =482.37 \: \rm mph[/tex]
Using this value, we get the value of y as:
[tex]x + y =491.25\\y = 491.25 - x = 491.25 - 482.37 = 8.88 \: \rm mph[/tex]
Rounding to the nearest whole numbers, we get:
x = 482 mph, and y = 9 mph
Thus, the speed of the plane in still air is approx 482 miles per hour(mph). The speed of the jet stream, rounded to the nearest whole number, is 9 mph

Step-by-step explanation:
1. -10b+b=-9
It is like you are doing this:
-10+1=-9
5. 5k+7k=12k
5+7=12
3. 1+5v+v= 1+6v
Like: 5+1
2.-x-3x=-4x
Like:-3-1=4 (both are negative numbers and you just add the second one)
4.-7n-7-8+10n=3n-15
You are doing this with n:
10-7=3 and this with numbers:
-7-8=-15 (both negative again)
6.a-2+1+4a= 5a-1
Like this: 4+1=5 and -2+1=-1
7. 8(x+10)= 8*x+8*10= 8x +80
8. 8(1+6p)= 8*1+8*6p= 8+48p
9.-5(-7+7n)= 35-35n ( when you * negative and positive numbers you get negative result and when you * negative and negative numbers you get positive result)
10.-(9m+7)= -9m-7 ( when you have - before () every number changes its sign).

Step-by-step explanation:
Answer:
11.25 or 11 1/4
Step-by-step explanation:
seeing as how tiled in this sense essentially means 'cut' we have to look at the following rectangle as 2 separate rectangles instead of one whole
so we'll let the biggest rectangle be rectangle one and the smallest rectangle two-
now we need the dimensions of each one-
rectangle one
l=5 w=2
rectangle two
l=5 w=1/4
now let us set up the equation and solve-
a=lw
rectangle one
a=5*2=10
rectangle two
a=5*1/4=1.25
and the last step is to add together the areas of both rectangles
10+1.25=11.25
and since you need your answer as a mixed number the answer is 11 1/4
(to do this you just put 11.25 over 100 and then simplify)
good luck :)
