Answer: If you mean by the B symbol next to a bunch of points. Those are points you can earn depending on the question. For example, if I helped someone with their problem, I would receive the amount of points that they put up for that question. I’m pretty sure the points can also help you to rank up and give you a new title or something. Im new myself lol
Answer:
(22.74 ; 27.26)
Step-by-step explanation:
The confidence interval relation is stated as :
Mean ± Zcritical * σ/sqrt(n)
Mean = 25
σ = 6
The Zcritical at 95% = 1.96
Hence,
25 ± 1.96 * (6/sqrt(27))
25 ± 1.96 * 1.1547005
Lower boundary :
25 - (1.96 * 1.1547005) = 22.73678702
Upper boundary :
25 + (1.96 * 1.1547005) = 27.26321298
(22.74 ; 27.26)
Answer: -14
Step-by-step explanation: Here we're asked to simplify -|-14| so we
start by simplifying the absolute value of -14.
Remember that the absolute value of
any positive or negative integer is positive.
So the absolute value of -14 is 14.
So we write (14) in parenthses like I have just done.
Next, we bring down the negative sign
that was outside the absolute value.
So we're left with -(14) or -14.
