25 mi

Answers

Answer 1

Answer with step-by-step explanation:

The distance between Rockville and San Jose is 2407.2. Since there are 63360 inches in a mile, we divide it by 2, which is 31680. We multiply 2407.2 by 31680, and get 76260096.

The science teacher gives daily homework. For a random sample of days throughout the year, the median number of problems is 5 and the IQR is 2. The Spanish teacher also gives daily homework. For a random sample of days throughout the year, the median number of problems is 10 and the IQR is 1. If you estimate the median number of science homework problems to be 5 and the median number of Spanish problems to be 10, which is more likely to be accurate? Explain your reasoning.

Answers

Answer:

SCIENCE SEEMS MORE ACCURATE

Step-by-step explanation:

The interquartile range (IQR) = difference between the upper and lower quartile (Q3 - Q1)

The median can be estimated as :

(Q3 - IQR/2) or (Q1 + IQR/2).

FOR SCIENCE:

MEDIAN NUMBER = 5

IQR = 2

IQR = Q3 - Q1

Q3 = median + IQR/ 2 = 5 + 2/2 = 6

Q1 = median - IQR/2 = 5 - 2/2 = 4

FOR SPANISH:

MEDIAN = 10

IQR = 1

IQR = Q3 - Q1

Q3 = median + IQR/ 2 = 10 + 1/2 = 10.5

Q1 = median - IQR/2 = 10 - 1/2 = 9.5

Science has a lower median score and an interquartile range which is reasonable wider than Spanish with a larger median value (but a very narrow interquartile range).

Suppose that a tea company estimates that its monthly cost is C(c) = 500x² + 100x and its monthly revenue is R(2) = -0.6x3 + 700x2 – 400x + 300, where x is in thousands of boxes of tea sold. The profit is the difference between the revenue and the cost. What is the profit function, p(X)?
O A. P(x) = 0.6x3- 200x2 + 500x+ - 300

OB. P(x) = -0.6x3 + 1200x2 – 300x + 300

O C. P(x) = -0.6x3 + 200x2 – 500x + 300

D. P(xl = 0.6x3 + 200x2 – 500x + 300​

Answers

Answer:

p(x) = 0.6x³ - 200x² + 500x- 300

Step-by-step explanation:

Given the cost function and revenue function as:

C(x) = 500x² + 100x

R(x) = -0.6x³ + 700x² – 400x + 300

To get the profit function:

p(x) = C(x) - R(x)

p(x) = 500x² + 100x -(-0.6x³ + 700x² – 400x + 300)

open the parenthesis

p(x) = 500x² + 100x + 0.6x³ - 700x² + 400x - 300

p(x) = + 0.6x³+500x² - 700x² + 100x+ 400x- 300

p(x) = 0.6x³ - 200x² + 500x- 300

Hence the profit function is expressed as p(x) = 0.6x³ - 200x² + 500x- 300

Simon score 4x10^2 points in a game. Joe scored 2x10^3 points in the same game. whose score is higher? how much higher?​

Answers

Answer:

Joe scored higher by 1600

Step-by-step explanation:

Given

[tex]Simon = 4 * 10^2[/tex]

[tex]Joe = 2 * 10^3[/tex]

Solving (a): Which is higher?

First, we need to convert both numbers to whole numbers

[tex]Simon = 4 * 100[/tex]

[tex]Simon = 400[/tex]

[tex]Joe = 2 * 10^3[/tex]

[tex]Joe = 2 * 1000[/tex]

[tex]Joe = 2000[/tex]

2000 is greater than 400;

Hence, Joe score higher

Solving (b): By how much?

We simply calculate the difference

[tex]Difference = Joe - Simon[/tex]

[tex]Difference = 2000 - 400[/tex]

[tex]Difference = 1600[/tex]

The probability of a tourist visiting an area cave is 0.70 and of a tourist visiting a nearby park is 0.60. The probability of both places on the same day is 0.40. The probability that a tourist visits at least one of these two places is

Answers

The probability that the tourist visits atleast one of the two places is 0.90

Probability of cave visit, P(C) = 0.70

Probability of park visit = P(N) = 0.6

Probability of both = P(B) = 0.40

The probability of visiting atleast one of the two places can be defined thus :

P(Atleast one) = P(C) + P(N) - P(B)

P(Atleast one) = 0.70 + 0.60 - 0.40

P(Atleast one) = 0.90

Therefore, the probability of visiting atleast one of the two places is 0.90

The expression 10=1,000 is obviously false, but we can make it true by rewriting it with an exponent.

Note that 1,000=10*10*10

Or, equivalently:

     To solve this problem, we use the order of operation:

  Now solve the parentheses first;

The relative risk of being a college graduate for Boone County residents as compared to Cooper County residents is

Answers

Answer:

The relative risk of being a college graduate for Boone County residents as compared to Cooper County residents is 3.11.

Step-by-step explanation:

Denote the events as follows:

C = Cooper County resident

B = Boone County resident

G = graduate

NG = non-graduate

The information provided is summarized as follows:

               G       NG     Total

     C       18       82       100

     B       28      22        50

Total       46      104      150

Compute the relative risk of being a college graduate for Boone County residents as compared to Cooper County residents as follows:

[tex]\text{Relative Risk}=\frac{\text{Graduates in Boone County}}{\text{Graduates in Cooper County}}[/tex]

                      [tex]=\frac{28/50}{18/100}\\\\=\frac{28}{50}\times \frac{100}{18}\\\\=3.11111\\\\\approx 3.11[/tex]

Thus, the relative risk of being a college graduate for Boone County residents as compared to Cooper County residents is 3.11.

The relative risk of remaining a college graduate for Boon County residents in comparison to Cooper County residents would be 0.500

Relative risk:

Relative risk is used in the statistical analysis of the data of ecological, cohort, medical, and intervention studies, to estimate the strength of the association between exposures (treatments or risk factors) and outcomes. Mathematically, it is the incidence rate of the outcome in the exposed group.

The relative risk is calculated by dividing the probability of an event for group 1 divided by the probability of an event occurring for group 2.
