The length is 14 how I know it.
you don't know the value of the length so you will represent length by "X", you know you get the volume multiplying height by width by length so you multiple all the values.
6×10(X)=840
10(X)=140
X=14
if you do not know this process in detail leave it in the comments and I'll explain it, for now the value of length will be 14
Answer:
The phrase "95% confident" means that there is a 95% confidence that the true mean parking time of students from within the various college on campus is included in the interval (9.1944, 11.738).
Step-by-step explanation:
The (1 - <em>α</em>)% confidence interval for population parameter implies that there is a (1 - <em>α</em>) probability that the true value of the parameter is included in the interval.
Or, the (1 - <em>α</em>)% confidence interval for the parameter implies that there is (1 - <em>α</em>)% confidence or certainty that the true parameter value is contained in the interval.
From the provided data the 95% confidence interval for the population mean parking time of students from within the various college on campus is:
CI = (9.1944, 11.738)
This 95% confidence interval implies that the true mean parking time of students from within the various college on campus is included in the interval (9.1944, 11.738) with a specific probability or confidence of 95%.
Thus, the phrase "95% confident" means that there is a 95% confidence that the true mean parking time of students from within the various college on campus is included in the interval (9.1944, 11.738).
Answer:
110
Step-by-step explanation:
= 120+100/2
=220/2
=110
CLASS MARK = HIGHEST OBSERVATION +LOWEST OBSERVATION BY 2
Y varying directly with x means y equals a constant multiplying x: y=kx
in this case, k=4, so 84=4x
x=21
the second one is the answer <i think>
