Answer: Median
Step-by-step explanation:
some sport superstars are paid extremely huge salaries, but this is not always the case for all spott stars. Since the mean is largerly influenced by the large salaries the data becomes unrelaible When estimating the center but reliable when it comes down to representing the center. With this reason is why the median would be considered.
Solve for x over the real numbers:
-5 + 1/5 + 3/x = 9/20
-5 + 1/5 + 3/x = 3/x - 24/5:
3/x - 24/5 = 9/20
Bring 3/x - 24/5 together using the common denominator 5 x:
-(3 (8 x - 5))/(5 x) = 9/20
Cross multiply:
-60 (8 x - 5) = 45 x
Expand out terms of the left hand side:
300 - 480 x = 45 x
Subtract 45 x + 300 from both sides:
-525 x = -300
Divide both sides by -525:
Answer: x = 4/7
Answer:
D
Step-by-step explanation:
A function is written in slope intercept form (y = mx + b)
so we first have to find the y-intercept or "b" in the question it states that they started off 400 miles away so that would be the "b" then you would need to find the m or slope and in the question it says after seven hours they where 50 miles away and 400 minus 50 is 350 so they traveled 350 miles in 7 hours so you then have to divide 350 by 7 and you get the slope 50 but since it is to find out how far away they are we make it negative giving you the equation y = -50 +400. Hope you found this helpful :D
Answer:
Because of cars, and factories making it everyday.
Step-by-step explanation:
Answer:
A. 12x² + 15xy + 18x
B. - 12x² + 18xy + 24x
C. 10x² - 31x - 14
D. x² - 36
3a. x = 8
3b. x = 3
Step-by-step explanation:
A. 3x ( 4x + 5y +6 ) C. ( 2x - 7 ) ( 5x + 2 )
12x² + 15xy + 18x 10x² + 4x - 35x - 14
10x² - 31x - 14
B. 6x ( 3y - 2x + 4 )
18xy - 12x² + 24x D. ( x + 6 ) ( x - 6 )
-12x² + 18xy + 24x x² - 6x + 6x - 36
x² - 36
3a. 5/4x + 2 = 12 3b. 7/3x - 2 = 5/3x
5/4x = 12 - 2 -2 = 5/3x - 7/3x
5/4x = 10 -2 = - 2/3x
x = 10 · 4/5 -2/3x = -2
x = 8 x = 3
