2x-3y=7
-3y = -2x+7
y= 2x/3-7/3
slope of 2/3 (rise 2, run 3)
y-intercept of -7/3
Would be a positive line, starting low on left and rising towards right
There should be sixteen branches. There are four possible suits for the first card, hearts, diamonds, clubs, spades. Then each of those four branches has four branches for the second card drawn. 4*4 = 16.
Answer: 1.53
Step-by-step explanation:
The given data : 4, 4, 4, 4, 6, 8
Number of data values : n= 6
The mean value of the given data will be :-
The formula to find standard deviation:_
![\sqrt{\dfrac{\sum(x-\overline{x})^2}{n}]](https://tex.z-dn.net/?f=%5Csqrt%7B%5Cdfrac%7B%5Csum%28x-%5Coverline%7Bx%7D%29%5E2%7D%7Bn%7D%5D)
Now,
The standard deviation will be :-
This is a true statement, or false depending on whether Alfonso actually did or not. There's no proof.
