Step-by-step explanation:
All you have to do is add up all that yardsgained and subtract the yards lost:
32-7+15-2=38
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:(0,4)
Step-by-step explanation:
4x+5y=20
4(0)+5y=20
5y=20
5x/5=20/5
y=4
4x+5(4)=20
4x+20=20
-20 -20
4x=0
4x/4=0/4
x=0
4x+5y=20
4(0)+5(4)=20
0+20=20
20=20
I think this is right
Answer:
EX. 210/6
Step 1. Set up the equation, 210/6
Step 2. Divide the first digit/number 6 x 30 = 180 210 - 180 = 30
Step 3. rewrite the equation that is left, 30/6 6 x 5 = 30 30 - 30 = 0
Step 4. Only if need be for another equation, repeat step 1 and 2 until you have your answer
The Answer to the equation 210/6 is 35
Try 426/6 by yourself, please don't use a calculator.
