Answer: 5/6
Step-by-step explanation:
probabilities = possibilities/outcome
To get an even you can possible roll 2, 4, 6 with 6 total outcomes
P(even) = probability of getting an even = 3/6
To get a divisor of 3: only 3 and 6 can be divided by 3
P(divisor of 3)=2/6
Because of the or in the statement, you add the 2 probabilities
P(even or divisor of 3) = 3/6+2/6 = 5/6

According to the question we have ,The plane's difference in cruise altitude between after the initial 15 minutes of flight until just before it started its descent into Albany was 4,683 feet. The right answer is A.
Is altitude the same as height?Height: The vertical distance between the measurement point and the point from which the observation was made. Altitude is the vertical distance from the measurement place to mean sea level.
After the first fifteen min of the flight, the aircraft's cruising altitude changed by = 33,427 ft - 28,744 ft = 4,683 ft before it started its descent towards Albany.
therefore we have 4,683ft as the answer.

suppose we have a coin that has 0.7 probability of landing on heads when flipped. we can model the outcome of each flip as a bernoulli random variable y , where y
In this scenario, the outcome of each flip of the coin can be modeled as a Bernoulli random variable Y, where Y takes the value 1 (heads) with a probability of 0.7 and the value 0 (tails) with a probability of 0.3.
A Bernoulli random variable is a discrete random variable that can take only two possible outcomes, typically labeled as success (1) and failure (0), with a fixed probability associated with success. In this case, the outcome of each flip of the coin can be represented by the Bernoulli random variable Y, where Y = 1 represents the event of getting heads and Y = 0 represents the event of getting tails.
Given that the probability of landing on heads is 0.7, we can assign the following probabilities to the outcomes:
P(Y = 1) = 0.7 (probability of getting heads)
P(Y = 0) = 0.3 (probability of getting tails)
Thus, for each individual flip of the coin, we can use the Bernoulli random variable Y to model the outcome, where Y takes the value 1 (heads) with a probability of 0.7 and the value 0 (tails) with a probability of 0.3.

Ratio of three angles of a triangle is 1 : 2 : 3. Find the angles.
Answer:
30⁰ , 60⁰ , 90⁰
Step-by-step explanation:
Let the angles x , 2x , 3x
By angle sum property:
x + 2x + 3x = 180⁰
6x = 180⁰
x = 30⁰
Angles are : 30⁰ , 60⁰ , 90⁰
Answer:
30°, 60°, 90°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the parts of the ratio, 1 + 2 + 3 = 6 parts
Divide to find the value of one part of the ratio
180° ÷ 6 = 30° ← value of 1 part of the ratio, thus
2 parts = 2 × 30° = 60°
3 parts = 3 × 30° = 90°
Thus angles are 30°, 60° and 90°
the price of a cup of coffee has risen to $2.75 today. yesterday's price was $2.40. find the percentage increase. round your answer to the nearest tenth of a percent.
To find the percentage increase in price from yesterday's price to today's price, we can use the following formula:
Percentage Increase = ((New Value - Old Value) / Old Value) x 100
Plugging in the given values, we get:
Percentage Increase = ((2.75 - 2.40) / 2.40) x 100
Percentage Increase = (0.35 / 2.40) x 100
Percentage Increase = 0.1458 x 100
Percentage Increase = 14.58%
Therefore, the percentage increase in price from yesterday's price to today's price is 14.58%, rounded to the nearest tenth of a percent.

The probability of success (p) would be 0.30 and the probability of failure (q) would be 0.70.
Binomial distributions are probability distributions of the number of successes in a fixed number of trials.
The probability of success (p) and the probability of failure (q) must remain the same for each trial.
The probability of success and failure can be represented as a proportion, a percentage, or a decimal.
The sum of the probabilities of success and failure must equal 1.
The mean of the binomial distribution is equal to np.
Where n is the number of trials and p is the probability of success.
The standard deviation of the binomial distribution is equal to npq, where n is the number of trials, p is the probability of success, and q is the probability of failure.
The z-table can be used to calculate the probability of a given number of successes or failures in a binomial distribution.
The sampling distribution of this study would be a binomial distribution, as it is a study of the proportion of first-time customers out of 100 orders.

Explanation:
This is a piecewise function. As the name implies, the g(x) is broken up into 3 pieces. Each piece depends on what the input x is.
If x is between \(-\infty\) and \(-7\), excluding both endpoints, then we pick the first piece. So in this case, \(g(x) = x^2-5\)
Or if \(-7 \le x \le 2\), then we go for the second piece and \(g(x) = 9x-17\)
Lastly, if x is between \(2\) and \(\infty\), then we go for the last piece and say \(g(x) = (x+1)(x-5)\)
------------------
To paraphrase that last section, we have g(x) defined as having a split personality or multiple identities depending on what x is.
If x is between negative infinity and -7 (exclusive), then g(x) = x^2-5If x is between -7 and 2, then g(x) = 9x-17If x is between 2 and infinity, then g(x) = (x+1)(x-5)------------------
The question is: which piece do we pick?
Well, g(7) means that x = 7 for g(x). We'll pick the third piece because 7 is between 2 and infinity. In other words, x = 7 makes \(x > 2\) a true inequality.
So,
\(g(x) = (x+1)(x-5) \ \text{ when } x > 2\\\\g(7) = (7+1)(7-5) \ \text{ replace every x with 7}\\\\g(7) = (8)(2)\\\\g(7) = 16\\\\\)

The length of each piece of wood will be 28 inches if divided into 25%.
To divide the wood into 4 equal pieces, we will divide the total quantity by 4. Thus, the fraction that we will get is 1/4th of total. Now, as per the known fact, 1/4 is 25%, which will be our required answer based on the criteria mentioned in question.

L < 1, the series is convergent according to the ratio test. The ratio test to determine if the given series is convergent or divergent.
The series we're analyzing is Σ(n^4)/(n^n) from n=1 to infinity. To use the ratio test, we need to evaluate the limit L as n approaches infinity for the absolute value of (a_(n+1))/a_n: L = lim (n→∞) |(a_(n+1))/a_n| = lim (n→∞) |((n+1)^4)/(n+1)^(n+1)) * (n^n)/(n^4)|
Now, we can simplify the expression: L = lim (n→∞) |(n^n * (n+1)^4) / (n^4 * (n+1)^(n+1))|
Notice that we can cancel out some terms: L = lim (n→∞) |((n+1)^4) / (n+1)^(n+1) * (n^n)/(n^4)|
Now, let's divide (n+1)^4 by (n+1)^(n+1): L = lim (n→∞) |(1 / (n+1)^n) * (n^n)/(n^4)|

Between the ages of 22 and 50, how much money would john spend on his habit if he continues to smoke two packs a day and each pack costs $5 how much will he spend if he smokes at the same rate from 22 to 70
Between the ages of 22 and 50, John would spend $102,200 on smoking, and between the ages of 22 and 70, he would spend $175,200 on smoking.
1. First, find the number of years John smokes between ages 22 and 50, and between ages 22 and 70:
- For ages 22 to 50: 50 - 22 = 28 years
- For ages 22 to 70: 70 - 22 = 48 years
2. Calculate the number of packs John smokes per year, given that he smokes 2 packs a day:
- 2 packs/day × 365 days/year = 730 packs/year
3. Calculate the cost of smoking per year, given that each pack costs $5:
- 730 packs/year × $5/pack = $3,650/year
4. Calculate the total cost of smoking for both age ranges:
- For ages 22 to 50: 28 years × $3,650/year = $102,200
- For ages 22 to 70: 48 years × $3,650/year = $175,200
If John continues to smoke at the same rate, he would spend $102,200 on smoking between the ages of 22 and 50, and $175,200 if he continues until the age of 70.

To find the solution of the compound inequality x − 2 > 4 or 5x ≥ 35, we need to solve each inequality separately and then combine their solutions using the OR operator.
Solving x − 2 > 4, we add 2 to both sides to get x > 6.
Solving 5x ≥ 35, we divide both sides by 5 to get x ≥ 7.
The solution of the compound inequality x − 2 > 4 or 5x ≥ 35 is the set of all values of x that satisfy at least one of the inequalities, which is x > 6 or x ≥ 7.
