Answer:
90% confidence interval for the mean weight loss for the population represented by this sample assuming that the differences are coming from a normally distributed population is [1.989 ,13.5105]
Step-by-step explanation:
The data given is
Mean Std Dev
Before 177.25 29.325
After 169.50 22.431
Difference 7.75 8.598
Hence d`= 7.75 and sd= 8.598
The 90% confidence interval for the difference in means for the paired observation is given by
d` ± t∝/2(n-1) *sd/√n
Here t∝/2(n-1)=1.895 where n-1= 8-1= 7 d.f
and ∝/2= 0.1/2=0.05
Putting the values
d` ± t∝/2(n-1) *sd/√n
7.75 ±1.895 * 8.598 /√8
7.75 ± 5.7605
1.989 ,13.5105
90% confidence interval for the mean weight loss for the population represented by this sample assuming that the differences are coming from a normally distributed population is [1.989 ,13.5105]
Answer:
Step-by-step explanation:
I still suspect that Angle A is 30° and Angle B is 60°. Otherwise the labels do not fit the illustration.
If Angle A is 60°, as you insist, then the solution (the length of x) is as follows:
opp side x
tan 60° = √3 = ---------------- = -----
adj side 7
Then:
√3 x
----------- = -----
1 7
Thru cross-multiplication we see that x = 7√3
Multiply both sides by 7, which produces:
7√3 = x
<em>195 m^3</em>
Step-by-step explanation:
The equation for the volume of a triangular prism is...
In this equation, b is the base, h is the height, and l is the length. We simply need to plug everything in from the problem into the equation, then solve. To also make this easier, I'm going to change the 1/2 to a 0.5.
<u>195 m^3</u>
