Answer:
D
Step-by-step explanation:
Shapes like trapezoids have one pair of parallel sides, and other shapes such as rhombuses have at least one.
The answer is C, First you must find the length of the diagonal gravel path and you can use Pythagorean Theorem to do this. 24^2+32^2=c^2 and solve for c which will get you 40 feet. Now, solve for the area of the path by multiplying 40*2 (2 feet wide) which will get you an area of 80 square feet. Multiply 80 by 3.5 and then the answer is $280. Hope this helped you :)
Answer:
The standard error of your estimate of the average height in the city is 0.5 inches.
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean and standard deviation , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean and standard deviation .
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
You begin by collecting the heights of a random sample of 196 people from the city.
This means that
The standard deviation of the heights in your sample is 7 inches.
This means that
The standard error of your estimate of the average height in the city is
The standard error of your estimate of the average height in the city is 0.5 inches.
I think its the second one... (hope its right)
