On a coordinate grid, 1 square unit equals 14 square mile. A rectangular walking path has vertices at (−4, 5) (1, 5), (−4, -5) a
AfilCa [17]

Answer:

126 square miles

Step-by-step explanation:

So I just draw a grid and mark the thingies (sorry my math vocabulary is not very good)

So you get a rectangle that is 5x9 if you connect the dot thingies and 9 square units is 14 square miles and 9x14=126. Using a coordinate grid makes it easier to visualize what you’re doing

The mean of birth weights for individual babies in the population is 3,500 grams. What is the mean birth weight for the sampling
Gala2k [10]

Answer:

The mean birth weight for the sampling distribution is

3,500 grams.

Step-by-step explanation:

The sample mean is the average of the sample values collected divided by the number of the samples, while the population mean is the average or mean of all the values in the population.  If the sample is random and the sample size is large enough, then the sample mean would be a good estimator of the population mean.  This implies that with a randomly distributed and unbiased sample size, the sample mean and population mean will be equal, according to the central limit theorem. Therefore, the mean of the sample means will always approximate the population mean.

AlexFokin [52]

Options

A. The number of cars passing through the intersection in one hour

B. The number of pedestrians crossing the intersection in one hour

C. The number of bicyclists crossing the intersection in one hour

D. The number of food trucks that park within four blocks of the intersection

E. The number of minutes for a car to get from the intersection to the administration building

Answer:

The number of minutes for a car to get from the intersection to the administration building

Step-by-step explanation:

A variable is said to be discrete if and only if it has a countable number of values. While a variable is said to be continuous if it can take infinitely many values.

Option a to d contains discrete variables (1 hour) and (4 blocks), so they can't be regarded as the right option. 1 hour and 4 blocks are specified values and they can't take any other fraction of values aside 1 and 4 respectively.

Looking at option e, the variable, number of minute as stated in this option is a continuous variable. This is so because at any two interval of minutes, fractions and lots of a minute can always be recorded by the engineer to study the traffic flow
