To graph the inequality y ≤ x - 2 on the axes, you would:

Plot the line y = x - 2 on the graph. The line will be a straight line passing through the point (-2,0) and has a slope of 1.

Determine the direction of the inequality symbol. Since it is a less-than-or-equal-to symbol, we will shade the region that is less than or equal to the line.

Shade the region that is less than or equal to the line in the graph. In this case, the region above the line y = x - 2.

The line is solid, it's not dotted.

Note: The graph will be a straight line that is tilted towards the top right of the coordinate axes, the region above the line will be shaded.

The number of fish caught during a fishing tournament is a discrete random variable.

A fishing tournament typically involves counting the number of fish caught by each participant. The number of fish caught is a whole number and cannot take on intermediate values. It is not possible to catch a fraction of a fish or have a continuous range of values. Therefore, the random variable representing the number of fish caught is discrete.

Discrete random variables are characterized by distinct and separate values with no intermediate possibilities. In the context of a fishing tournament, the number of fish caught can only take on specific values, such as 0, 1, 2, and so on. Each value represents a count or a whole number of fish caught by an individual participant.

The sequence {aₙ} converges to 4.

To determine if the sequence {aₙ} converges or diverges, we can analyze the behavior of the terms as n approaches infinity.

The nth term of the sequence is given by an = (4n² + 33n + 2)/(n² + 5n - 2).

As n approaches infinity, the dominant terms in the numerator and denominator become 4n² and n², respectively.

Therefore, we can simplify the expression by dividing both the numerator and denominator by n²:

an = (4n²/n² + 33n/n² + 2/n²)/(n²/n² + 5n/n² - 2/n²)

= (4 + 33/n + 2/n²)/(1 + 5/n - 2/n²)

Now, as n approaches infinity, the terms with 33/n and 2/n² tend to zero. Thus, we have:

aₙ ≈ (4 + 0 + 0)/(1 + 0 - 0) = 4/1 = 4

Since the limit of the terms of the sequence is a constant value (4), we can conclude that the sequence converges.

The limit of the sequence is 4.

Therefore, the sequence {aₙ} converges to 4.

A: To determine when the lizard is back on the water, we need to find the time when the height (h) is equal to 0. So we set the equation -12t^2 + 6t = 0 and solve for t.

-12t^2 + 6t = 0

Factor out common terms:

-6t(2t - 1) = 0

Set each factor equal to 0:

-6t = 0 or 2t - 1 = 0

Solving each equation:

-6t = 0 --> t = 0

2t - 1 = 0 --> 2t = 1 --> t = 1/2

So the lizard is back on the water at t = 0 seconds and t = 1/2 seconds.

B: The height of each jump can be determined by substituting the time (t) values into the equation h = -12t^2 + 6t.

For t = 0 seconds:

h = -12(0)^2 + 6(0)

h = 0

For t = 1/2 seconds:

h = -12(1/2)^2 + 6(1/2)

h = -12(1/4) + 6/2

h = -3 + 3

h = 0

So each jump has a height of 0 feet.

C: To find the time it takes to reach the highest point, we need to find the vertex of the parabolic equation -12t^2 + 6t. The time at the vertex represents the highest point.

The formula for the x-coordinate of the vertex of a quadratic equation in the form ax^2 + bx + c is given by -b/(2a). In this case, a = -12 and b = 6.

t = -6/(2(-12))

t = -6/(-24)

t = 1/4

So it takes 1/4 seconds to reach the highest point.

Therefore, the answers are:

A: The lizard is back on the water at t = 0 seconds and t = 1/2 seconds.

B: Each jump has a height of 0 feet.

C: It takes 1/4 seconds to reach the highest point.

The probability that the sum of two slips drawn at random without replacement from a hat containing slips numbered 1 to 10 is 5 is (d) 1/30.

To determine the probability, we need to count the number of favorable outcomes (pairs of slips whose sum is 5) and divide it by the total number of possible outcomes (all pairs of slips that can be drawn without replacement).

There are three favorable outcomes: (1, 4), (2, 3), and (3, 2). These pairs add up to 5.

To calculate the total number of possible outcomes, we consider that the first slip can be any of the 10 numbers, and the second slip can be any of the remaining 9 numbers (since we are drawing without replacement). Therefore, there are 10 * 9 = 90 possible outcomes.

The probability is then given by 3 (favorable outcomes) divided by 90 (possible outcomes), which simplifies to 1/30. Therefore, the probability that the sum of the two slips is 5 is 1/30, corresponding to option (d).

The probability that the sum of the numbers on the two drawn slips is 5, is 2/45.

The subject of this question is probability. We have to find the probability that the sum of two randomly drawn slips is 5. The possible ways of drawing two slips whose sum is 5 are (1,4), (4,1), (2,3) and (3,2). So, there are 4 successful outcomes. The total number of outcomes is 10 choose 2, which is 45. Hence, the probability is the number of successful outcomes divided by the total number of outcomes. Thus the probability that the sum of the numbers on the two drawn slips is 5 equals 4/45 = 2/45. So, the correct answer is (c) 2/45.

a) Expected value = 50b.

b) Probability = 0.4c.

c) Probability that the game would take longer than 40 minutes is 0.2.

Let's discuss it further below.

In this question, we are given that the time required to play a certain game is uniformly distributed between 25 and 45 minutes. We are asked to find the expected value and variance of the time to complete the game, the probability of finishing within 33 minutes, and the probability that the game would take longer than 40 minutes.

a) To find the expected value and variance of the time to complete the game, we can use the following formulas:

Expected value = (minimum value + maximum value) / 2Variance = [(maximum value - minimum value)²] / 12

Using these formulas, we can calculate:

Expected value = (25 + 45) / 2 = 35Variance = [(45 - 25)²] / 12 = 50b.

b) To find the probability of finishing within 33 minutes, we can use the formula for a uniform distribution:

Probability = (x - minimum value) / (maximum value - minimum value)

Plugging in the values we know, we get:

Probability = (33 - 25) / (45 - 25) = 0.4c.

c) To find the probability that the game would take longer than 40 minutes, we can use the same formula as in part b, but with a different value for x:

Probability = (45 - 40) / (45 - 25) = 0.2

Therefore, the probability that the game would take longer than 40 minutes is 0.2.

Answer:

it is a right triangle

Step-by-step explanation:

i have no explanation my sister told me with no explanation sorry

Answer:

Yes, the three segments 16,30,34 make a right triangle.

Step-by-step explanation:

The three segments are the following 16,30, and 34.

We will use the Pythagorean Theorem to find out if the three numbers can make a right triangle.

- \(a^2+b^2=c^2\)

When we have 3 numbers given, our largest number is the hypotenuse.

So 34 is our hypotenuse, so we substitute it as the c in our formula.

And our a^2 and b^2 are 16 and 30!

- \(16^2+30^2=34^2\\256+900=1156\\1156=1156\)

Our formula verifies that the three segments provided can make a right triangle.

It is plausible to say that one group has a higher proportion of smokers than the other.

The meaning of 95% confidence in the given interval is that there is a 95% chance that the population mean is within the interval. This means that if we were to take repeated samples and calculate confidence intervals, 95% of those intervals would contain the true population mean.

To find the difference in proportions of male and female students who smoke, we define the parameters as the difference in proportions between the two groups.

The value of the sample statistic that estimates the difference of proportions, using correct notation, would be the difference in proportions in the sample.

To find a 99% bootstrap confidence interval using percentiles, we can use a tool like Statkey. This will give us a range of values within which we can be 99% confident that the true difference in proportions lies.

To find a 95% bootstrap confidence interval using margin of error, we can use the standard error estimate from the bootstrap distribution. This will give us a range of values within which we can be 95% confident that the true difference in proportions lies.

Based on the 99% confidence interval, it is unlikely that the proportions of all male and female students who smoke are the same. The confidence interval does not include zero, suggesting a significant difference between the two groups.

Therefore, it is plausible to say that one group has a higher proportion of smokers than the other.

There are 120 boats in the marina using algebraic equation.

We shall represent the number of boats in the marina with the letter x so that we derive an algebraic equation to solve for x as follows:

number of white boats = 5x/6

number of blue boats = 2/5 of (x - 5x/6)

number of blue boats = 2/5 × x/6

number of blue boats = x/15

number of red boats = 12

so that;

5x/6 + x/15 + 12 = x

LCM of the denominators is 30

(25x + 2x + 360)/30 = x

27x + 360 = 30x {cross multiplication}

30x - 27x = 360 {collect like terms}
