After plotting the data from the table, with the number of times sick per year as a function of the number of apples eaten per week, I can conclude that there is no definite correlation between the two variables. This is because the data points do not have a good fit with any trend, meaning the R-squared value is low. Thus, the number of apples eaten per week has no significant effect on the number of times the people listed get sick per year.
Well it really depends on how many of each fruit was bought but i guess it would be a+b=c
10 and try using photomath it helps.
The series
given is an example of arithmetic progression. The standard form of this series
is:
an = a + (<span><span>n − 1)</span> d</span>
Where,
<span>a = value of
the 1st term = 6b</span>
an = value
of the nth term
d = common
difference
n = how many
terms to add
<span>To calculate
for the common difference d, let us use the 1st term and 2nd
term. (any terms can be used as long as they are in succession)</span>
d = a2 – a1
d = 3b – 6b
d = -3b
<span>Substituting
all known value to the 1st equation:</span>
an = 6b
+ (<span><span>n − 1)</span> (-3b)</span>
an = 6b -3bn +3b
an = -3bn + 9b
Since there are only 5
terms therefore n = 1 to 5. The sigma notation is:
<span>D. sigma,
n=1, 5 above the sigma, -3bn+9b</span>
