Answer:
4 kg of sugar would contain [tex] 1.2 \times 10^9 [/tex] crystals.
Step-by-step explanation:
Given that 3kg of sugar contains 9 × 10⁸ crystals, let "x" represent the number of sugar crystals 4kg of sugar would contain.
Thus, set up a proportion as follows:
3 kg : 9 × 10⁸ = 4 kg : x
[tex] \frac{3}{9 \times 10^8} = \frac{4}{x} [/tex]
Solve for x. Cross multiply.
[tex] 3 \times x = 9 \times 10^8 \times 4 [/tex]
[tex] 3x = 36 \times 10^8 [/tex]
[tex] 3x = 3.6 \times 10^9 [/tex]
Divide both sides by 3
[tex] \frac{3x}{3} = \frac{3.6 \times 10^9}{3} [/tex]
[tex] x = 1.2 \times 10^9 [/tex]
4 kg of sugar would contain [tex] 1.2 \times 10^9 [/tex] crystals.

Step-by-step explanation:
Two different drugs, X and Y, are currently in use to treat a certain condition. About 7 percent of the people using either drug experience side effects. A random sample of 75 people using drug X and a random sample of 150 people using drug Y are selected. The proportion of people in each sample who experience side effects is recorded. Are the sample sizes large enough to assume that the sampling distribution of the difference in sample proportions is approximately normal?
(A) Yes. Both sample sizes are large enough.
(B) No. The sample size for drug X is large enough, but the sample size for drug Y is not.
(C) No. The sample size for drug Y is large enough, but the sample size for drug X is not.
(D) No. Neither sample size is large enough.
(E) There is not enough information provided to determine whether the sampling distribution is approximately normal.
Answers
Answer:
C
Step-by-step explanation:
No. The sample size for drug Y is large enough, but the sample size for drug X is not.
The sample size would be greater than 100 to get a significant result, so, option C is correct.
What is percentage?A percentage, often known as percent, is a division by 100. Percentage, which means "per 100," designates a portion of a total sum. 45 out of 100 is represented by 45%, for instance. Finding the percentage of a whole in terms of 100 is what percentage calculation is. Both manual calculation and the use of internet calculators are options.
Given:
A random sample of 75 people using drug X and a random sample of 150 people using drug Y is selected,
The majority of statisticians concur that a sample size of 100 is necessary to obtain any form of significant results. If your population is less than 100, you should definitely survey every single person.
Thus, the sample size for drug X is not enough.

Step-by-step explanation:
Given that the correct point-slope form is;
y - b = m(x - a)
So she made an error in writing y + 1, that part is wrong.
So the equation that was written wrongly is; y+1=1/2(x−3)
We have to rewrite the entire equation;

I have a cockroach problem in my living room. Don't ask how but I counted 64 cockroaches today. And they are
growing at a rate of 25% every day.
How many cockroaches do you think I'll have after three days?
Answers
If they are growing at a rate of 25% every day you can expect to have approximately 100 cockroaches in your living room.
What is growth rate?Growth rate refers to the rate at which something (such as a population, a quantity, or a value) increases or decreases over a certain period of time.
Assuming that the growth rate is compounded daily, we can calculate the number of cockroaches you will have after three days using the formula for exponential growth:
[tex]N = N_0(1 + r)^t[/tex]
Where:
N₀ is the initial number of cockroaches (64 in this case)
r is the growth rate (25% or 0.25 in decimal form)
t is the time in days (3 in this case)
N is the number of cockroaches after t days
Plugging in the values, we get:
[tex]N = 64(1 + 0.25)^3[/tex]
[tex]N = 64(1.25)^3[/tex]
N = 64(1.5625)
N = 100
Thus, after three days, you can expect to have approximately 100 cockroaches in your living room.

Step-by-step explanation:
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?
Answers
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.

4) Millions of Americans work full-time at or near minimum wage. Still, many of them struggle to
afford rent, childcare, and other expenses and rely on public assistance programs such as food
stamps and Medicaid. To help these "working poor,” some people think the government should
raise the minimum wage from $7.25/hour to $15/hour. If this happened, how do you expect it
would impact workers at the restaurant?

Rewrite 2x2−x−12 and 1x2−16 as equivalent rational expressions with the lowest common denominator.
Answers
Answer:
[tex]\mathbf{\dfrac{2(x+4)}{(x-4)}= \dfrac{(x+3)}{(x-4)}}[/tex] are the rational expressions.
Step-by-step explanation:
To rewrite [tex]\dfrac{2}{x^2-x-12}[/tex] and [tex]\dfrac{1}{x^2-16}[/tex] as equivalent rational expressions
i.e.
[tex]\dfrac{2}{x^2-x-12}=\dfrac{1}{x^2-16}[/tex]
By factorization:
[tex]\dfrac{2}{x^2-4x+3x-12}=\dfrac{1}{(x-4)(x+4)}[/tex]
[tex]\dfrac{2}{x(x-4)+3(x-4)}=\dfrac{1}{(x-4)(x+4)}[/tex]
[tex]\dfrac{2}{(x-4)(x+3)}=\dfrac{1}{(x-4)(x+4)}[/tex]
By multiply both sides with ( x+3) & (x+4), we get:
[tex](x+3) (x+4) \times \dfrac{2}{(x-4)(x+3)}=(x+3) (x+4) \times \dfrac{1}{(x-4)(x+4)}[/tex]
[tex]\mathbf{\dfrac{2(x+4)}{(x-4)}= \dfrac{(x+3)}{(x-4)}}[/tex] are the rational expressions

Please help!
Answers
Answer: 8 8/9
Step-by-step explanation:
From the question, we are informed that Mark was remodeling his house and that he took 26 2/3 square feet from 3 different rooms.
The average change in square footage per room will be calculated as:
= 26 2/3 ÷ 3
= 80/3 × 1/3
= 80/9
= 8 8/9
Therefore, the answer is D.
