Answer:
4
Step-by-step explanation:
45+65=110
110x4=440
Im assuming this is a non biased 6 sided dice,
multiples of 3 would be 3 and 6 therefore chance of rolling one would be 2/6 = 1/3.
however since the question says two dice at the same time, you have to multiply the probability which would be 1/3 x 1/3 = 1/9
X^3 / X^5 = X^ -2
you have to subtract the exponents when you’re dividing
Answer: I think it is -0.4
Step-by-step explanation:
Answer:
d) Squared differences between actual and predicted Y values.
Step-by-step explanation:
Regression is called "least squares" regression line. The line takes the form = a + b*X where a and b are both constants. Value of Y and X is specific value of independent variable.Such formula could be used to generate values of given value X.
For example,
suppose a = 10 and b = 7. If X is 10, then predicted value for Y of 45 (from 10 + 5*7). It turns out that with any two variables X and Y. In other words, there exists one formula that will produce the best, or most accurate predictions for Y given X. Any other equation would not fit as well and would predict Y with more error. That equation is called the least squares regression equation.
It minimize the squared difference between actual and predicted value.
