Answer: the value of x is 14
Step-by-step explanation:
Answer:
Option D is correct.
Step-by-step explanation:
Regression analysis determines the relationship between 2 or more variables by examining the influence of independent variables on a dependent variable.
Few requirements for regression analysis are like - quantitative data condition, the outlier condition, error independence etc.
The following is not a requirement for regression analysis:
D:The method for regression analysis line is not robust. It is seriously affected by a small departure from a normal distribution.
Answer:
x equals 1 and 5
Step-by-step explanation:
x^2-6x+5
Factor: (x-1) (x-5)
The Zeroes: 1 and 5
The zeroes are the numbers that make the equation equal to zero.
Answer:
<u>So, the way a ratio works is </u><u>"for every 1 of this, we have 4 of this"</u><u> for example. (the ratio I just described would be 1:4.) </u>

I believe I've seen this question before. If the ratio of dolls to teddy bears is 9:3 then for every 9 dolls you have 3 teddy bears.
So, since we have 240 dolls and a 9:3 ratio to teddy bears, all we have to do is take how many dolls we have (240) and divide it by 3 to see how many teddy bears we have.
So:
240 ÷ 3 = 80
If your ratio is 9:3, then 80 is your answer.
<u>Hope this helps and have a nice day!</u>

X^2+3x-5
x=(-3±√(9+20))/2
x=(-3±√29)/2
D is the closest thing to the right answer, it just doesn't have any of the mathematical symbols in it
