Based on the expected profit to Honey, and the probability of the various customers using the coupons, all customers except customer 4 should be sent coupons.
What is the expected profit for all customers?The profit to Honey if people use the coupons is:
= Revenue - Cost
= 1 - 0.05
= $0.95
The profit if the coupon is not used is the cost of $0.05.
Customer 1 expected profit:
= P(coupon used) × Profit if coupon used + (1 - P(coupon used)) × Profit if coupon not used
= (0.47 x 0.95) + ( (1 - 0.47) x -0.05)
= $0.42
Customer 2 expected profit:
= (0.35 x 0.95) + ( (1 - 0.35) x -0.05)
= $0.30
Customer 3 expected profit:
= (0.27 x 0.95) + ( (1 - 0.27) x -0.05)
= $0.22
Customer 4 expected profit:
= (0.03 x 0.95) + ( (1 - 0.03) x -0.05)
= -$0.02
Customer 5 expected profit:
= (0.08 x 0.95) + ( (1 - 0.08) x -0.05)
= $0.03
In conclusion, all customers expect customer 4 should be sent the coupons as they result in profits.

A health research institute collects information from 20 individuals on the number of years they have spent smoking cigarettes, and their age of death. The data is summarized below:
∑x=1257
∑y^2=836
∑x^2=98823
∑y=116
∑(xy)=8249
Find the correlation coefficient (r):
The correlation coefficient of the health research institute data measures the relationship between the age and the years of the smokers
The correlation coefficient is 0.53
How to calculate the correlation coefficientThe correlation coefficient (r) is calculated as:
[tex]r = \frac{n(\sum xy) - \sum x \sum y}{\sqrt{[n \sum x^2 - (\sum x)^2][n\sum y^2 - (\sum y)^2}}[/tex]
Using the given parameters, we have:
[tex]r = \frac{20 *8249 - 1257* 116}{\sqrt{[20 * 98823 - 1257^2][20 * 836 - 116^2}}[/tex]
Evaluate the exponents
[tex]r = \frac{20 *8249 - 1257* 116}{\sqrt{[20 * 98823 - 1580049][20 * 836 - 13456}}[/tex]
Evaluate the products
[tex]r = \frac{164980 - 145812}{\sqrt{[1976460 - 1580049][16720 - 13456}}[/tex]
Evaluate the differences
[tex]r = \frac{19168}{\sqrt{[396411*3264}}[/tex]
Evaluate the product
[tex]r = \frac{19168}{\sqrt{1293885504}}[/tex]
Evaluate the root
[tex]r = \frac{19168}{35970.6}[/tex]
Evaluate the quotient
[tex]r = 0.53[/tex]
Hence, the correlation coefficient is 0.53

A store paid $240.00 for a dining table.The manager of the store marks up the table by 125%.what is the new price of the dining table?
Answer:
$300
Step-by-step explanation:
$240 × 125% is $300
We can use the method of calculating the percentage of an amount to find out the discount amount. The new price of the dining table will be $300.
How to calculate unit price of something?Unit means 'single entity', the fundamental constructing block. Usually, it is 1 in mathematics and science.
Thus, unit price of something is price of 1 thing.
Therefore, suppose we're taking about price of mangoes, then unit price will denote the price of 1 mango.
We have been given that A store paid $240.00 for a dining table and The manager of the store marks up the table by 125%.
Therefore, 125% of $240
$240 × 125%
$240 × 1.25
= $300
Hence, the new price of the dining table will be $300.
We can use the method of calculating the percentage of an amount to find out the discount amount.

It appears that people who are mildly obese are less active than leaner people. One study looked at the average number of minutes per day that people spend standing or walking. Among mildly obese people, the mean number of minutes of daily activity (standing or walking) is approximately Normally distributed with 376 minutes and standard deviation 70 minutes. The mean number of minutes of daily activity for lean people is approximately Normally distributed with 526 minutes and standard deviation 106 minutes. A researcher records the minutes of activity for an SRS of 6 mildly obese people and an SRS of 6 lean people.
Required:
a. What is the probability that the mean number of minutes of daily activity of the 6 mildly obese people exceeds 410 minutes?
b. What is the probability that the mean number of minutes of daily activity of the 6 lean people exceeds 410 minutes?
Answer:
0.9963 is the probabilities that mean number of daily activity of 6 lean people exceed 410 minutes.
Step-by-step explanation:
Solution:
6 Mildly obese people exceed 410 minutes.
Given:
Mean = µ = 376
Standard deviation = ∂ = 70
n = 6
p (x> 410) = p (z > x - µ/ ∂ / √n)
= p (z > 410 – 376 / 70 /√6 )
= p (z > 1.185)
= 1 – p (z < 1.185)
= 1 – 0.38199
= 0.618
0.618 is the probability that the mean number of minutes of daily activity of 6 mildly obese people exceed 410 minutes.
6 lean people exceed 410 minutes:
Given:
Mean = µ = 526
Standard deviation = ∂ = 106
n = 6
=p(x > 410)
= p (z > x - µ/ ∂ /√n)
=p (z > (410 – 526 ) / 106 / √ 6 )
= p (z > - 2.67)
= p (z <2.68)
= 0.9963
0.9963 is the probabilities that mean number of daily activity of 6 lean people exceed 410 minutes.

The cone below has a base diameter of 20x cm. When the base of
The cone rests on horizontal ground it exerts a pressure of 650 N/m^2
a) Calculate the weight of the cone in terms of x and pie
Since the cone has a base diameter of 20x cm, the weight of the cone in terms of x and pie is 6.50πx² N
Pressure on the groundThe pressure on the horizontal ground due to the cone is given by P = W/A where
W = weight of cone and A = area of base of coneWeight of the coneMaking W subject of the formula, we have
W = PA
Since
P = pressure = 650 N/m² and A = area of base of cone = πd²/4 where d = diameter of base of cone = 20x cm = 0.2x mSo, W = PA
W = Pπd²/4
W = Pπ(0.2x)²/4
W = 0.04Pπx²/4
W = 0.01Pπx²
Substituting the values of the variables into the equation, we have
W = 0.01Pπx²
W = 0.01 × 650 N/m² × π(x m)²
W = 6.50πx² N
So, since the cone has a base diameter of 20x cm, the weight of the cone in terms of x and pie is 6.50πx² N
