Total number of likes divided by the expenses.
2. Yes. According to both definitions, website A has more user engagement per a single dollar expense.
Step-by-step explanation:
Answer:
equation; P=A(1+r/n)^nt
P=principal amount
A=value of investment
r= interest rate in decimals
n=number of times compounded
t=time in years
P=1000(1+0.16/12)^12(5)= $2213.8 rounded

Answer:
And the z score for 0.4 is
And then the probability desired would be:
Step-by-step explanation:
The normal approximation for this case is satisfied since the value for p is near to 0.5 and the sample size is large enough, and we have:
For this case we can assume that the population proportion have the following distribution
Where:
And we want to find this probability:
And we can use the z score formula given by:
And the z score for 0.4 is
And then the probability desired would be:
Answer: The length of JF = 16 units.
Step-by-step explanation:
Given: In triangle DEF, segment DJ is a perpendicular bisector of side EF.
i.e. DJ is perpendicular to EF and DJ divides EF into two equal parts EJ and JF. [The perpendicular bisector is a line that is perpendicular to a line segment and splits it into two congruent segments.]
If EJ is 3y-8 and JF is 7y-40.
Then,
JF= 7(8)-40 =56-40= 16 units
Hence, the length of JF = 16 units.
