Find the second term in the sequence.
Answers
Answer:
c(2) = -10
Step-by-step explanation:
The first equation says that the first term of the sequence is -20.
The second equation is saying that to find any term of the sequence, add 10 to the previous term.
c(2) = c(2-1) + 10
c(2) = c(1) + 10
c(2) = -20 + 10 = -10
a company’s market share went from 50 to 65 percent of the total market. of the following choices, which two statements about the company's market shares are true?
Answers
The two statements that are true about the company's Market share going from 50 to 65 percent of the total market . The initial market share and multiply by 100, which gives 30 percent. Option B is correct answer.
The two statements that are true about the company's market share going from 50 to 65 percent of the total market are:
The company's market share increased by 30 percent: The difference between the initial market share of 50 percent and the final market share of 65 percent is 15 percentage points. To calculate the percentage increase, we can divide the difference by the initial market share and multiply by 100, which gives (15/50) x 100 = 30 percent.
The company's relative market position improved: With a market share of 65 percent, the company now holds a greater proportion of the total market than before. This means that its relative market position has improved compared to its competitors, who have a smaller share of the market. This could translate into increased bargaining power, profitability, and other benefits for the company.

Chloe has 4 sundaes for her friends. She has 12 8/9 ounces of sprinkles to put equally on the sundaes. How many ounces of sprinkles will be on each sundae?
Answers
Answer:
3(2/9) ounces of sprinkles each sundae (3.222222.....)
Step-by-step explanation:
12 divided into 4 = 3 ounces
(8/9)/4 is the same as (8/9) x(1/4) = 8/36 = 2/9
3 ounces and 2/9 ounces
Each sundae will have 3 2/9 ounces of sprinkles on it.
What is the fraction?A fraction is defined as a numerical representation of a part of a whole that represents a rational number.
Chloe has 12 8/9 ounces of sprinkles and 4 sundaes, so she will put 12 8/9 / 4 = 3 2/9 ounces of sprinkles on each sundae.
To break this down, 12 8/9 can be simplified to 12 + 8/9 = 12 + 8/9 = 12 + 4/9 = 12 4/9.
When we divide 12 4/9 by 4, we get 3 2/9.
So each sundae will have 3 2/9 ounces of sprinkles on it.

it has been estimated that about 30% of frozen chicken contain enough salmonella bacteria to cause illness if improperly cooked. a consumer purchases 12 frozen chickens. what is the probability that the consumer will have more than 6 contaminated chickens?
Answers
The probability that the consumer will have more than 6 contaminated chickens is 0.039.
The binomial distribution is a frequency distribution that shows how many successful outcomes there could be in a set number of trials with an equal chance of success. Given a success probability of "p" for each experiment trial, it shows the likelihood that an experiment will succeed "x" times out of "n" trials. The formula to calculate this binomial distribution is \(P(X=x)= \;_nC_xp^x(1-p)^{n-x}\)
Given the p=0.30 and n=12. Then, the required probability that the consumer will have more than 6 contaminated chickens is,
\(\begin{aligned}P(X > 6)&= P(X=7)+P(X=8)+P(X=9)+P(X=10)+P(X=11)+P(X=12)\\&=12C_7(0.3)^7(0.7)^5\cdots\cdots\cdots12C_{12}(0.3)^{12}(0.7)^{0}\\&=0.0386\\&=0.039\end{aligned}\)
The required answer is 0.039.

A toxicologist wants to determine the lethal dosages for an industrial feedstock chemical, based on exposure data. The most appropriate modeling technique to use is most likely polynomial regression ANOVA linear regression logistic regression scatterplots
Answers
A toxicologist aiming to determine the lethal dosages for an industrial feedstock chemical based on exposure data would most likely utilize logistic regression.
So, the correct answer is D.
This modeling technique is appropriate because it helps predict the probability of an event, such as lethality, occurring given a set of independent variables like exposure levels.
Unlike linear regression, which assumes a linear relationship between variables, logistic regression is suitable for binary outcomes.
Polynomial regression and ANOVA may not be ideal in this case, as they focus on modeling different relationships between variables.
Scatterplots, on the other hand, are a graphical tool for data visualization and not a modeling technique.
Hence the answer of the question is D.

Answers
The approximate probability that the total score is at least 375 when a fair six-sided die is rolled 100 times is (d) 0.4420.
When a fair six-sided die is rolled, the random variable X represents the outcome. The mean (μX) of X is 3.5, and the standard deviation (σX) is 1.71.
To find the probability that the total score is at least 375 when the die is rolled 100 times, we can use the Central Limit Theorem. According to the theorem, the sum of a large number of independent and identically distributed random variables approximates a normal distribution.
In this case, the sum of the outcomes of 100 rolls of the die follows a normal distribution with a mean of μX multiplied by the number of rolls (100) and a standard deviation of σX multiplied by the square root of the number of rolls (10). Therefore, the approximate probability can be calculated by finding the probability that the sum is greater than or equal to 375.
Using a normal distribution table or a calculator, we can find that the approximate probability is 0.4420, which corresponds to answer (d). This means that there is a 44.20% chance that the total score will be at least 375 when the die is rolled 100 times.

Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.

Answers
To show that the alternating harmonic series is convergent using the Alternating Series Test, we need to verify three conditions:
The terms are positive: In the alternating harmonic series, the terms are defined as (-1)^n * 1/n. Although the individual terms alternate in sign, the absolute values of the terms are positive (1/n), satisfying this condition.
The sequence is nonincreasing: We observe that as n increases, the magnitude of each term decreases since 1/n is a decreasing function. Therefore, the sequence of absolute values, |1/n|, is nonincreasing.
The sequence of terms converges to zero: As n approaches infinity, the term 1/n converges to zero. This can be understood by considering the limit lim(n→∞) 1/n = 0. Since the terms approach zero, the sequence of terms satisfies this condition.
Since all three conditions of the Alternating Series Test are met, we can conclude that the alternating harmonic series is convergent.

Answers
The rule that describes this translation, given the first vertices, would be 5 units to the right and 4 units down.
How to find the translation rule ?To describe the translation from the point (2, 3) to the point (7, -1), we need to determine the rule or transformation that governs the movement of the coordinates.
In general, the rule for translating a point by a specific amount horizontally and vertically is given by:
(x, y) → (x + a, y + b)
Applying this rule to the given translation, we have:
(2, 3) → (2 + 5, 3 - 4)
(2, 3) → (7, -1)
Therefore, the rule that describes this translation is (x, y) → (x + 5, y - 4) or 5 units to the right and 4 units down.
