You would find the multiples 2 and 3 had in common
so may 6th, 12th, and 18th
2: 3:
4 6*
6* 9
8 12*
10 15
12* 18*
14
16
18*
I think you forgot to list the following.
<em>x = 41 cm</em>
<u><em>Here is why:</em></u>
For this question we have to use the pythagorean theorem, which is used for right triangles. The hypotenuse will always be the last in this theorem.
Plug in.
Add together.
Now we will find the square root of 1,681, since <em>c </em>is squared.
= 41 cm
X=10
Explaination:
130=8x+50
-50 -50
80=8x, then divide each side by 8 to get the variable alone
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]
