what would be the correct ration between the following ions: y1+ and X2- Show transcribed image...
The distance, d, between two points, (x1,y1)(x1,y1) and (x2,y2)(x2,y2), can be found using the formula d=√(x2−x1)^2+(y2−y1)^2. How can you rearrange the given formula to correctly find y2?
Recall that the distance between two points (x1, y1) and (x2, y2) on a Cartesian plane is given by Write a function to pass the four parameters, compute the correct distance, and return the results
Which of the following equation is correct for calculating the Euclidean Distance between two objects and y, assuming x1, x2 are the values for the two predictors of the object x, and y1, y2 are the values for the corresponding predictors of the object y 1x1 - y1]+\x2 - y21 o (x1 - y1)2 + (x2 - y2) O/0x1-yl)? +(x2 - y2)2 V1x1 - yıl +1x2 - y2T
Let X1, X2, X3 be independent Binomial(3,p) random variables. Define Y1 = X1 + X3 and Y2 = X2 + X3. Define Z1 = 1 if Y1 = 0; and 0 otherwise. Define Z2 = 1 if Y2 = 0; and 0 otherwise. As Z1 and Z3 both contain X3, are Z1 and Z3 independent? What is the marginal PMF of Z1 and Z2 and joint PMF of (Z1, Z2) and what is the correlation coefficient between Z1 and Z2?
Would you be able to distinguish between Cu2+ and Ni2+ ions in a solution if you added concentrated NaOH to the solution? What would you expect to happen? Write a balanced molecular and net ionic equation for both ions reacting with NaOH. Use Cu(NO3)2 and Ni(NO3)2 in your reactions for the respective ions. Show the correct phases of all species in reactions for full credit.

Consider the following two fun9ctions: y1= (x2+3x-1)/(x+4) ; y2= x-1+(3/x+4) Perform long division on Y1 to verify it equals Y2
The angle between two vectors u1=x1i+y1j+z1k and u2=x2i+y2j+z2k can be determined by cos()=(x1*x2+y1*y2+z1*z2)/(|u1|*|u2|), were |u1|=sqrt(x1^2+y1^2+z1^1). Given the vectors u1=3.2i-6.8j+9k and u2=-4i+2j+7k, determine the angle between them (in degrees) by writing one MATLAB command that uses element by element multiplication and the MATLAB built in functions acosd, sum, and sqrt. This is what I tried but i don't think it's correct because it should be one value and I got a vector u1=[3.2 -6.8 9] u2=[-4 2 7] theta=acosd(sum(u1.*u2)./sqrt(u1).*sqrt(u2)).
