How to solve?: First you will get you alike terms on the same side. You will do this by subtracting 5 on both sides of your sign and will therefore get the equation to where -5 and -3 is on the same side and looks like -5 - 3. Then you will combine your -5 and -3 and get -8. Now you will take your -2x and divide both sides by -2 to where your able to get your variable x alone. You will then get -8 divided by -2 and your answer would be -4.
Answer: -4
HOPE THIS HELPS! ^_^
Legs legnth a and b, and hypotnuse c
a^2+b^2=c^2
legs are 9 and 12
a=12
b=9
12^2+9^2=c^2
144+81=c^2
225=c^2
sqrt both sides
15=c
the legnth of the hyptonuse is 15 inches
Answer: (751.05, 766.95)
Step-by-step explanation:
We know that the confidence interval for population mean is given by :-
,
where =population standard deviation.
= sample mean
n= sample size
z* = Two-tailed critical z-value.
Given :
n= 42
We know that from z-table , the two-tailed critical value for 99% confidence interval : z* =2.576
Now, the 99% confidence interval around the true population mean viscosity :-
∴ A 99% confidence interval around the true population mean viscosity : (751.05, 766.95)
