To find the area of each backyard, we need to multiply the length and width together.
For Branda, her yard is 35 by 90, which means the area is 35*90 which = 3150.
For Laurie, her yard is 40 by 65, which means the area is 40*65 which = 2600.
Now, we are asked to find the difference between Branda and Lauries yard areas. The difference means how much larger Branda's area is than Lauries.
This means we have to subtract Laurie's area from Branda's.
So, we do 3150 - 2600 = 550
So, our answer is 550ft^2

Using the z-distribution, it is found that the 90% confidence interval for mean calories in a 30-gram serving of all chocolate chip cookies is (143, 149).
We are given the <em>standard deviation</em> for the population, which is why the <em>z-distribution </em>is used to solve this question.
The information given is:
- Sample mean of
.
- Population standard deviation of
.
- Sample size of
.
The confidence interval is:
The critical value, using a z-distribution calculator, for a <u>95% confidence interval</u> is z = 1.645, hence:


The 90% confidence interval for mean calories in a 30-gram serving of all chocolate chip cookies is (143, 149).
