Answer:
(1) Please find attached the graph of the data
(2) 160.396 m
(3) The correlation that exist is a straight line correlation
Step-by-step explanation:
The given data are;
Distance, Time
(m), (s)
50, 6.1
100, 12
150, 18.3
200, 25.2
250, 31.7
(2)
Based on the linear regression formula, we have;
The line is
y = 7.7581×x+5.234
When t = 20 s, we have
y = 7.7581*20+5.234 = 160.396 m
(3) The correlation that exist is a straight line correlation
Step-by-step explanation:
you know the answerv noow
Answer:
Leaving as a radical form
Why?
Because that's the whole value if you convert it to a decimal you cannot write all the numbers, and in the radical form it has all the numbers
It would be useful when we are working with equations for example the quadratic equation, if you get that x=√5, you would want the exact value. And there are more useful
Answer:
8.7
Leg
Step-by-step explanation:
-1*x^2= -1
-1*(1)^2
-1*1= -1
