Suppose about 900,000 people live in an area of 1,800 square miles. What is the best estimate for the population density?
alukav5142 [94]

Answer:

The Population Density is 500\ People/mi^2.

Step-by-step explanation:

Given,

Total number of People = 900,000

Total Land Area = 1800 sq. mi.

Solution,

For calculating the population density, we have to divide the total number of people by the area of the land.

This can be framed in equation form'

Population\ Density=\frac{Total\ Number\ of\ People}{Land\ Area}

Now putting the given values, we get;

Population\ Density=\frac{900,000}{1800\ mi^2}=500\ People/mi^2

Hence The Population Density is 500\ People/mi^2.

dimulka [17.4K]

Answer:

Vector u has u_x = (5 - 15) = -10, and u_y = -4 - 22 = -26, and its component form would be u = -10i - 26j.

If vector v is in the opposite direction: 10i + 26j

And if it is double in magnitude: v = 20i + 52j

Hope this helps you! Ask me anything if yu have any quistions!

48. Reading Rates The reading speed of sixth-grade students is approximately normal, with a mean speed of 125 words per minute a
son4ous [18]

Answer:

The reading speed of a sixth-grader whose reading speed is at the 90th percentile is 155.72 words per minute.

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

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.

In this problem, we have that:

\mu = 125, \sigma = 24

What is the reading speed of a sixth-grader whose reading speed is at the 90th percentile

This is the value of X when Z has a pvalue of 0.9. So it is X when Z = 1.28.

Z = \frac{X - \mu}{\sigma}

1.28 = \frac{X - 125}{24}

X - 125 = 1.28*24

X = 155.72

The reading speed of a sixth-grader whose reading speed is at the 90th percentile is 155.72 words per minute.
