Answer:
27,115 m
Step-by-step explanation:
In order to find the area of any location, you need multiply length by width. So, multiply 18.7 m x 1450 m and it equals 27,115 m
First, let's find the equivalent of 1 meter to each of the US Standard choices (inches, feet, yards, miles).
1 meter = 39.37 inches = 3.28 feet = 1.09 yards = 0.00062 miles
Now, to find the metric equivalent of each of the choices, we multiply each of these by 4 (since we need to find a measurement equivalent to 4 meters), and check them against the choices.
A. 0.28 miles.
0.00062 x 4 = 0.0025
0.0025 is much smaller than 0.28, so that won't work.
B. 4.38 yards
1.09 x 4 = 4.36
4.36 is 0.02 smaller than 4.38, so it's pretty darn close.
C. 12.4 feet
3.28 x 4 = 13.12
13.12 is slightly bigger than 12.4, but it's not as close as in B.
D. 136.2 inches
39.37 x 4 = 157.48
157.48 is considerably bigger than 136.2, so that doesn't work, either.
The two that are closest are B and C, but B is closer by far.
If you round to the nearest tenth, 4.36 becomes 4.4, and 4.38 becomes 4.4
This means that B, 4.38 yards, is as equivalent a measurement as you're going to get with these choices.
Therefore the answer is B: 4.38 yards.

Answer:
a) 0.16
b) 0.0518
c)
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean and standard deviation , the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
For a proportion p in a sample of size n, we have that the mean is and the standard deviation is
In this problem, we have that:
a. Find the mean of p, where p is the proportion of minority member applications in a random sample of 2100 that is drawn from all applications.
The mean of p is 0.16.
b. Find the standard deviation of p.
c. Compute an approximation for P ( p leq 0.15), which is the probability that there will be 15% or fewer minority member applications in a random sample of 2100 drawn from all applications. Round your answer to four decimal places.
This is the pvalue of Z when X = 0.15. So
has a pvalue of 0.4247
