HELP PLEASE ASAP. A video rental store keeps a list of their top 15 movie rentals each week. This week the list includes 6 actio
n,
4 comedies, 3 dramas, and 2 mysteries. The store manager removes a copy of each of the 15 movies from the shelf, then randomly selects 3 of the 15 to
show on the display monitors in the store. What is the probability that she selected 2 comedies and 1 action movie? EXPLAIN how the probability would
change if two more comedy movies were added to the list in place of the 2 mystery movies.
NOT SURE THE ANSWER IN THE PIC.

Answer:
y=4.8710 is the missing value
Step-by-step explanation:
The first step in approaching this question is determining the exponential equation that models the set of data. This can easily be done in Ms.Excel application. We first enter the data into any two adjacent columns of an excel workbook. The next step is to highlight the data, click on the insert tab and select the x,y scatter-plot feature. This creates a scatter-plot for the data.
The next step is to click the Add chart element feature and insert an exponential trend line to the scatter plot ensuring the display equation on chart is checked.
The exponential regression equation for the data set is given as;
To find the missing y value, we simply substitute x with 2 in the regression equation obtained;
Answer: 0.0667117 * miles
Step-by-step explanation: The Earth is one astronomical unit from the sun i.e.1AU= 93 million miles.The angular speed of the Earth traveling around the sun is approximately 0.9863 degrees per day. If we assume the orbit of the Earth is completely circular, what is the linear speed in miles per hour?
Step-by-step explanation: First, a day has 24 hours. Knowing how far the earth travels in day we can say:
0,9863 degrees/day = 0,9863 degrees/(24 hours)
0,9863 degrees/day = 0.0411 degrees/hours
Also, we know the orbit completely circular, so the total distance on, degrees, is 360°. Also this distance can be know with the formula:
Total Circuference = 360° = 2*pi* R
Because Radius is variable for any circle. It is say that:
360° = 2*pi radians
WIth this relation, we can know how many radians are 0.0411 degrees
360/0.0411 = (2*pi)/x
x = (2*pi*0.0411)/(360)
X = 0.00071733032
X is how much the Earth travels per hour in Radians.
Multiplying per Radius:
Earth distance traveled per hour = 0.0667117 * miles
Answer:
($13,300,$46,900)
Step-by-step explanation:
We are given the following in he question:
Mean, μ = $30,100
Standard Deviation, σ = $5,600
Chebyshev's Theorem:
- According to theorem atleast
percent of data lies within 2 standard deviations of mean.
- For k = 3,
Thus, 89% of data lies within three standard deviation of mean.
Thus, we expect at least 89% of new car prices to fall within ($13,300,$46,900)
