What is 0 equals 5y plus 20-x in slope intercept form?
0 = 5y + 20 - xso 5y = x - 20or y = (1/5)x - 40 = 5y + 20 - xso 5y = x - 20or y = (1/5)x - 40 = 5y + 20 - xso 5y = x - 20or y = (1/5)x - 40 = 5y + 20 - xso 5y = x - 20or y = (1/5)x - 4
X varies directly with y and inversely with z x equals 20 when y equals 8 and z equals 4 Find x when y equals 4 and z equals 8?
The answer is x=10. If: x=20 y=8 z=4 then: y=8/2=4 z=4*2=8 since x varies directly with y, meaning whatever happens to y, happens to x, so if y was divided by 2, then x should be divided by 2. After all, the inverse of division is multiplication.
40 is what percent of 200 please explain?
40% of 200 is 80. To find, multiply 200 by 0.4.
A set of 3 numbers is the sum of 110 the median is forty and the range is thirty?
Let's say that this numbers are placed in order as x, y, z. So the median is y = 40, and the range is the difference between z and x. So z - x = 30. The sum is: x + y + z = 110 Substitute 40 for y, and x + 30 for z; x + 40 + (x + 30) = 110 2x + 70 = 110 subtract 70 to both sides. 2x = 40 divide by 2 to both sides; x = 20 so, z = x + 30 z = 20 + 30 = 50 Thus these numbers are 20, 40, and 50.

If x varies jointly as y and the square as z and x equals 40 when y equals 20 and z equals 2 find x when y equals 30 and z equals 3?
As x ∝ yz2 then x = kyz2 where k is a constant. Substituting the given figures, 40 = k*20*22 = 80k Then k = ½ and the formula is, x = ½yz2 So, x = ½ * 30 *32 = 135
If x varies jointly as y and the square as z and x equal 40 when y equal 20 and z equal 2 find x when y equal 30 and z equal 3?

What is 0 equals 5y plus 20-x in slope intercept form?
0 = 5y + 20 - xso 5y = x - 20or y = (1/5)x - 40 = 5y + 20 - xso 5y = x - 20or y = (1/5)x - 40 = 5y + 20 - xso 5y = x - 20or y = (1/5)x - 40 = 5y + 20 - xso 5y = x - 20or y = (1/5)x - 4

Which correlation coefficient best describes the relation between X and Y below X10 20 30 40 50 Y 80 70 60 50 40 a -1 b 1?
-1. Y falls as X rises. In fact the PMCC is precisely -1 (i.e. a perfect negative correlation).
