The ratio of three numbers is 4 : 5 : 3. The sum of the numbers is 54. List the numbers in ratio form.
Answer:
13.5 : 18 : 22.5.
Step-by-step explanation:
let the numbers be 3x , 4x and 5x
3x+ 4x + 5x = 54
12x = 54
x = 4.5
so the numbers are 3*4.5, 4 * 4.5 and 5 * 4.5
= 13.5, 18 and 22.5.
The list of the numbers in ratio form is 18 : 22.5 : 13.5
Given the ratio of three numbers as 4 : 5 : 3
Total ratio = 4 + 5 + 3
Total ratio = 12
If the sum of the numbers is 54.
For the ratio of 4:
= 4/12 * 54
= 1/3 * 54
= 18
For the ratio of 5:
= 5/12 * 54
= 270/12
= 22.5
For the ratio of 3:
= 3/12 * 54
= 1/4 * 54
= 13.5
Hence the list of the numbers in ratio form is 18 : 22.5 : 13.5

Choose whether the expression is a result of multiplying
conjugates together, squaring binomials, or neither.
25c^2 + 55c + 30
-multiplying conjugates
-squaring binomials
-neither
-both
Answer:
neither
Step-by-step explanation:
Take out 5 as a common factor. It will be easier to look at.
5(5c^2 + 11c + 6)
5(5C +6 )(c + 1 )
Now you can put the 5 inside.
(25c + 30)(c + 1) is one answer.
(5c + 6)(5c + 5) is another.
The answer is multiplying binomials. There is nothing that that is squared and the answers are not conjugates. They are two binomials multiplied together.

s^2+2s-6=0
s=
s=
Please answer this ASAP ! And with step by step expiation please !
Answer:
s = - 1 ± [tex]\sqrt{7}[/tex]
Step-by-step explanation:
Given
s² + 2s - 6 = 0 ( add 6 to both sides )
s² + 2s = 6
To complete the square
add ( half the coefficient of the s- term )² to both sides
s² + 2(1)s + 1 = 6 + 1
(s + 1)² = 7 ( take the square root of both sides )
s + 1 = ± [tex]\sqrt{7}[/tex] ( subtract 1 from both sides )
s = - 1 ± [tex]\sqrt{7}[/tex]
Thus
s = - 1 - [tex]\sqrt{7}[/tex] , s = - 1 + [tex]\sqrt{7}[/tex]

A basketball is thrown upward from a height of 1.8 m at a velocity of 12 m/s. How long until it reaches the ground?

There is a 0.9989 probability that a randomly selected 29-year-old male lives through the year. A life insurance company charges $197 for insuring that the male will live through the year. If the male does not survive the year, the policy pays out $100,000 as a death benefit.
Required:
a. From the perspective of the 29-year-old male, what are the monetary values corresponding to the two events of surviving the year and not surviving?
b. If the 29-year-old male purchases the policy, what is his expected value?
c. Can the insurance company expect to make a profit from many such policies? Why?
a. Surviving the year: $197; Not surviving the year: $100,000
b. Expected value: $306.78
c. The insurance company can expect to make $86.49 in profit per policy.
We have,
a.
From the perspective of the 29-year-old male:
Surviving the year:
The monetary value is the cost of the insurance premium, which is $197.
Not surviving the year:
The monetary value is the death benefit paid out by the policy, which is $100,000.
b.
To calculate the expected value for the 29-year-old male, multiply the probability of each event by its corresponding monetary value and sum them up:
Expected Value = (Probability of Surviving * Monetary Value of Surviving) + (Probability of Not Surviving * Monetary Value of Not Surviving)
= (0.9989 * $197) + (0.0011 * $100,000)
= $306.78
c.
Expected Premium Revenue
= Probability of Surviving * Premium Amount
= 0.9989 * $197
≈ $196.49
Expected Payout
= Probability of Not Surviving * Death Benefit
= 0.0011 * $100,000
≈ $110
Profitability
= Expected Premium Revenue - Expected Payout
= $196.49 - $110
≈ $86.49
Since the expected premium revenue exceeds the expected payout, the insurance company can expect to make a profit from many such policies.
In this scenario, the insurance company can expect to make $86.49 in profit per policy.
Therefore,
a. Surviving the year: $197; Not surviving the year: $100,000
b. Expected value: $306.78
c. The insurance company can expect to make $86.49 in profit per policy.

a. From the perspective of the 29-year-old male:
Surviving the year: The cost of insurance is $197.
Not surviving the year: The policy pays out a death benefit of $100,000.
b. The 29-year-old male's expected value is -$86.8013, indicating a potential loss.
c. Yes, the insurance company can expect to make a profit. The expected value is negative, meaning the company collects more in premiums than it pays out on average.
a. From the perspective of the 29-year-old male:
Surviving the year: The cost of insuring that the male will live through the year is $197.
Not surviving the year: The policy pays out a death benefit of $100,000.
b. To calculate the expected value for the 29-year-old male, we need to consider the probabilities of each event and their corresponding monetary values.
Expected Value = (Probability of surviving * Monetary value of surviving) + (Probability of not surviving * Monetary value of not surviving)
Probability of surviving = 0.9989
Monetary value of surviving = -$197 (since this represents the cost of insurance)
Probability of not surviving = 1 - Probability of surviving = 1 - 0.9989 = 0.0011
Monetary value of not surviving = $100,000
Expected Value = (0.9989 * -$197) + (0.0011 * $100,000)
Expected Value = -$196.8013 + $110
Expected Value = -$86.8013
Therefore, the expected value for the 29-year-old male is approximately -$86.8013.
c. The insurance company can expect to make a profit from many such policies because the expected value is negative (-$86.8013). The cost of insuring the male is $197, but the expected value is significantly less. This means that on average, the insurance company will collect more in premiums than it pays out in claims, resulting in a profit. The small probability of not surviving the year and the high payout of $100,000 contribute to the insurance company's ability to make a profit by spreading the risk among many policyholders.
