The Y-intercept is showing how many candy bars were sold in 2000 since x is every year after 2000 (hope that makes sense)
Answer:
3.14
Step-by-step explanation:
Given that:
Mean weight (m) = 79 ounces
Population standard deviation (s) = 13.1
Sample size = 47
Maximal margin of error associated with 90% confidence interval.
The margin of error is given by:
Zcritical * (standard deviation / sqrt(sample size)
Z critical at 90% confidence interval = 1.645
Hence,
Zcritical * (standard deviation / sqrt(sample size)
1.645 * 13.1 / sqrt(47)
1.645 * (13.1 / 6.8556546)
1.645 * 1.9108313
Hence, the margin of error is :
3.1433174885
= 3.14
Answer:
5y+6x-40=0
Step-by-step explanation:
y-2=-6/5(x-5)
5y-10=-6(x-5)
5y-10=-6x+30
5y+6x-10-30=0
5y+6x-40=0
The given function is that is a cubic polynomial
when arranged in descending order that is from highest degree to lowest degree
Since it is a three degree polynomial it has three roots.
According to rational root theorem , the possible roots of the above expression that is factors of 
=
are 
As you can see from the graph all roots of this polynomial are real.
The smallest positive root is 0.954 and smallest negative root are -0.724.
f(x) = x^2 - 16 (x+4)(x-4)
----- ------------ = ---------------- = x-4 Please note: this is not true for x = -4, because
g(x) = x+4 x+4 of the div. by zero it causes.
