b) 7/19 chance (I'm not 100% sure)
Step-by-step explanation:
A) since there are 8 prime numbers from 1-19 we can say that the probability is 8 over 19 or 8/19
Answer:
First, we bring the equation to the form ax²+bx+c=0, where a, b, and c are coefficients. Then, we plug these coefficients in the formula: (-b±√(b²-4ac))/(2a) . See examples of using the formula to solve a variety of equations.
Ok so its a guessing game
I say its 40+10 because
40-10{one # is 10 less than)=30
10(3){three times the other number}=30
so 40+10=50
Answer:
6ft i think
Step-by-step explanation:

Answer:
For a line of best fit, it doesn't nessesarily have to land on a point, it just has to be in between them or on them whichever way you choose to do it. And also your second question, yes it is correlation if it lines up with the line and not somewhere else or if there are so many dots that they don't really form a line then it isn't a correlation.
Hope this helps!
