Answer:
I'll give the scale factor and you can compute the coordinates of S
Step-by-step explanation:
the dilation if centered about the origin is the scale factor multiplied by each coordinate.
so looking at points V and U, the scale factor F is found by solving for F:
-6xF= -8
F=8/6=4/3
Now you can compute the coordinates for S

Answer:
Assuming ages are normally distributed, the 98% confidence interval for the population average age is [26.3, 35.7].
Step-by-step explanation:
We have to construct a 98% confidence interval for the mean.
The information we have is:
- Sample mean: 31
- Variance: 49
- Sample size: 15
- The age is normally distributed.
We know that the degrees of freedom are

Then, the t-value for a 98% CI is t=2.625 (according to the t-table).
The standard deviation can be estimated from the variance as:

The margin of error is:

Then, the CI can be constructed as:

You subtract 3 cents and add up how many months it is tiil it reaches the same ammout as adding 5 cents and adding up six months every time
