Step-by-step explanation:
254mm = 25.4 cm = 0.254 m
Coordinates of P = (6, -4)
Now, Transformation occurs in Horizontal direction, so x-ccordinate will change in the transformation.
x-coordinate = 6 - 12 = -6
In short, Your Answer would be: Option 3) (-6, -4)
Hope this helps!
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:
c
Step-by-step explanation:
10*10=100
100-78.54=21.46
so rounded answer is c or 21.5
goodluck on your test
