Answer:
186
Step-by-step explanation:
The sample mean, x, is the central value in the confidence interval, that is, the average between the upper and lower bounds of the interval.
In this case, the Lower bound is 184.00 and the upper bound is 188.00. Therefore, the sample mean is given by:
The mean length, in seconds, of the sampled songs is 186.00.
Answer:
its B.) 24 minutes
Step-by-step explanation:
i just took the test on edge.
<u>Answer:</u>
The correct answer option is a) y =2.
<u>Step-by-step explanation:</u>
We are given the following equation and we are to find the solution of this equation:
Here, the expression 
is given in a modulus, which means that its value cannot be negative.
Ignoring the negative sign because of mod.
y = 2
Well it simplifies to -23x-3 so i would say 4 is ur answer
Just substitute in the domain
f(-3)=9-9-7=-7
f(2)=4+6-7=3
f(5)=25+15-7=33
the range is {-7,3,33}
