Answer:
a) 0.0002
b) 0.0057
c) 0.0364
Step-by-step explanation:
Lets start by stating the probabilities of a person belonging to each policy:
Standard: 0.3
Preferred: 0.5
Ultra- Preferred: 0.2
The probability of person belonging to each policy AND dying in the next year:
Standard: 0.3 x 0.015 = 0.0045
Preferred: 0.5 x 0.002 = 0.001
Ultra- Preferred: 0.2 x 0.001 = 0.0002
a) The probability a ultra - preferred policy holder dies in the next year is 0.001. To find the probability of a person being both a ultra - preferred policy holder AND die in the next year is: 0.001 x 0.2= 0.0002
b) The probability is given by adding the probabilities calculated before :
0.0045 + 0.001 + 0.0002 = 0.0057
c) We use the results above again. This is 0.0002 / (0.001 + 0.0045). The answer comes out to be 0.0364
It is 2/3 I believe
By calculating the difference between the x and y coordinates, and putting it in the rise/run format, you can easily find the slope of the line
Answer:
Perimeter = 86.4 (m)
Step-by-step explanation:
A square (with side x) has an area of 466.56 (m^2)
=> x^2 = 466.56
=> x = sqrt(466.56) = 21.6
=> Perimeter of this square: P = 4(x) = 4(21.6) = 86.4 (m)
Hope this helps!
Complete question :
Jeremiah plans on building a 5 meter long garden walkway that is paved with square stones that measure " 5/6 meter on each side. There will be no spaces between the stones. How many stones will be needed to complete the garden walkway?
Answer:
12
Step-by-step explanation:
Given that:
Length of square block to be used = 5/6 meters
Length of garden. Walkway = 5 m
Since length of walkway is the same on both sides, then the Total length = 5m + 5m = 10 meters
Number of square stones required :
Total length of walkway / side length of stones to be used
= 10 meters ÷ (5/6) meters
= 10 * 6/5
= 60 / 5
= 12 stones
Using it's concept, it is found that the mean absolute deviation of 2.8 means that the heights differ from the mean by an average of 2.8 inches.
<h3>What is the mean absolute deviation of a data-set?</h3>
- The mean of a data-set is given by the sum of all observations divided by the number of observations.
- The mean absolute deviation of a data-set is the sum of the absolute value of the difference between each observation and the mean, divided by the number of observations.
- The mean absolute deviation represents the average by which the values differ from the mean.
In this problem, the mean is given by:
M = (65 + 58 + 64 + 61 + 67)/5 = 63.
Hence the mean absolute deviation is given by:
MAD = (|65-63| + |58-63| + |64-63| + |61-63| + |67-63|)/5 = 14/5 = 2.8.
The mean absolute deviation of 2.8 means that the heights differ from the mean by an average of 2.8 inches.
