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
To give a simple answer
if you consider the equation to be that of a line.
then if the variables cancel out, then the two lines will have the same slope.
two lines with the same slope fall under two categories. Parallel lines, and lines on top of each other
parallel lines have no solutions since the lines never cross each other
lines on top of each other have infinitely many solutions since they "cross" everywhere on the line
If 93% of the bar is silver, then the bar is 0.93*8.15 ounces of silver. Solving that makes there 7.58ish ounces of silver in the bar
I believe that the answer to your question in b = 0.
Answer:
8 students,
15 cans of juice and 11 packs of cheese cracker
Step-by-step explanation:
Mariam’s uncle donate 120 cans of juice and 90 - 2 = 88 packs of cheese cracker (eats two packs) for the school picnic.
Factor these numbers:

The greatest common factor is

so the greatest number of students who can share the food equally is 8 and each student will get
cans of juice and 11 packs of cheese cracker.
