As te car gets older the value depreciates because it gets used and put through rough roads or accidents. the newer the car is the better shape it is in and the higher value it would have.
You multiply 5 times 10, which gives you 50. This is the length of one side. Since it's a square, all sides are the same length.
Answer: 50cm x 50cm
I believe it’s a trapezoid but i’m not too sure... sorry :((
Answer:
Point Estimate for different between population means = - 0.99
Step-by-step explanation:
We are given data of two samples and we have to find the best point estimate of the true difference between two population means. Remember that in absence of data about population the best estimator is the sample data. So, we will find the means of both sample data and find the difference of that means. This difference between the means of sample data will be the best point estimate for the true difference between the population means.
Formula to calculate the mean is:

Mean of Sample 1:

Mean of Sample 2:

Therefore the best point estimate for difference between two population means would be = Mean of Sample 1 - Mean of Sample 2
= 128.55 - 129.54
= - 0.99
