Graph is negative and increasing in the interval x = - to x = a

A graph is included in the question in this case.

If the graph of any function is moving downward over a specific time interval, we know that. Function then starts to decline during that period.

If the graph of any function is rising during a specific interval. Function then increases throughout that specific time period.

A graph is positive when it is oriented above the horizontal axis.

It can be seen in the accompanying graph that the function's graph is below the x-axis between the values of x = - to x = a as it is oriented below the horizontal axis and graph is increasing

So

a. The sampling method that I would use for the given scenario is stratified random sampling.

b. The sampling method that I would use for the given scenario is systematic sampling.

Stratified random sampling is the most effective way to get accurate results in this situation. The university wants to conduct a mail survey of its alumni to collect information about their current employment status to justify charging a higher tuition rate than other universities. Stratified random sampling divides the population into strata based on certain characteristics.

In this case, strata would be the alumni that have different degrees from the university. The information collected through this method will be more representative of the population than simple random sampling. It ensures that each stratum is represented accurately in the sample. It also minimizes the variability within each stratum. It is an effective way of ensuring that each stratum is properly represented.  

Systematic sampling involves selecting every kth element from a list of the population. In this situation, the Environmental Protection Agency (EPA) wants to inspect a sample of 1000 containers from the 40,000 containers known to be in landfills to determine if leakage from the containers has occurred. As the exact location of the containers is no longer known, systematic sampling can be used.

EPA can select every 40th container from the list of the population, as 40,000/1000 = 40. In this way, they will have a random sample of 1000 containers from the 40,000 containers. This sampling method is less time-consuming and more cost-effective than other sampling methods. It also ensures the sample is representative of the entire population.

Step-by-step explanation:

the sum of the interior angles in a triangles is 180°

take off 62° and 95° from 180°

180 - 62 - 95 = 23°

Answer: y = (5)(2)x-10

Step-by-step explanation:

The final answer would depend on the specific number of adults and children provided as input. The code would execute the appropriate if-else conditions and print the most cost-effective ticket option accordingly.

The given Java code is a basic template for implementing a cost-effective ticket buying strategy at an amusement park. It takes input for the number of adults and children visiting the park and suggests the most suitable ticket option.

The flowchart logic is as follows:

1. If the total number of adults and children is equal to or greater than 10, the group rate is the most cost-effective option, and the code directs you to buy the group pass.

2. If there are at least 2 adults, but not enough visitors for the group rate, the code suggests buying only individual tickets.

3. If there are fewer than 2 adults, the code checks if there are at least 3 children. If so, it suggests buying the family pass.

4. If there are fewer than 2 adults and fewer than 3 children, the code suggests buying only individual tickets.

Based on the given flowchart and Java code, the cost-effective ticket buying strategy would be as follows:

• If the total number of adults and children is 10 or more, buy the group pass at $7 per person.

• If there are at least 2 adults, but fewer than 10 visitors, buy only individual tickets at $9 per adult and $7 per child.

• If there are fewer than 2 adults and at least 3 children, buy the family pass at $35.

• If there are fewer than 2 adults and fewer than 3 children, buy only individual tickets at $9 per adult and $7 per child.

In conclusion, the final answer would depend on the specific number of adults and children provided as input. The code would execute the appropriate if-else conditions and print the most cost-effective ticket option accordingly.

It will take the town 21 years 4 months to reach 4600 in population

a rate is a ratio that compares two different quantities which have different units. For example, if we say John types 50 words in a minute, then his rate of typing is 50 words per minute. The word "per" gives a clue that we are dealing with a rate.

initial population = 3000

population increase every year = 2.5% of 3000

which is 2.5/100 x 3000 = 75

let the time taken to reach 4600 be d

increment for d number of years = 75d

Total population after d years is 75d + 3000

so 75d + 3000 = 4600

75d = 4600  - 3000

75d = 1600

d = 1600/75

d = 21.33 years which is 21 years 4 months

The value of the expression "true && !false" can be determined by evaluating each part separately and then combining the results.

1. The "!" symbol represents the logical NOT operator, which negates the value of the following expression. In this case, "false" is negated to "true".

2. The "&&" symbol represents the logical AND operator, which returns true only if both operands are true. Since the first operand is "true" and the second operand is "true" (as a result of the negation), the overall expression evaluates to "true".

Therefore, the value of the expression "true && !false" is "true".

The only possible statement is option I, x > y > z. The correct answer is A. I only. Since z⁴ is always less than or equal to y², which is always less than or equal to x, we know that x > y² > z⁴ > 0.

Taking the square root of y² > z⁴, we get y > z² > 0.

Therefore, we know that y is greater than z², and since x is greater than y², we can also say that x is greater than z⁴.

With this information, we can eliminate option II as it suggests that z is greater than x, which we know is not true.

We can also eliminate option III as it suggests that z is greater than y, which we know is not true either.

Therefore, the only possible statement is option I, x > y > z.

The inverse function is given by f⁻¹(x) = 1.06x.  2 euros is equivalent to 2.12 U.S. dollars. 4 euros is equivalent to 4.24 U.S. dollars

Given that: the two different currencies is modeled by a linear function f(x) = x/1.06

where, x = an amount in U.S. dollars and f(x) = the equivalent amount in euros

To find the inverse function f⁻¹(x). Let y = f(x):

y = x/1.06

x = 1.06y

Since x = f⁻¹(y) = 1.06y

Thus, f⁻¹(x) = 1.06x

Note: f⁻¹(x) will help you convert from euros to dollar

2 euros to dollars will be:

f⁻¹(x) = 1.06x

f⁻¹(2) = 1.06(2) = 2.12

Thus, 2 euros is equivalent to 2.12 U.S. dollars

4 euros to dollars will be:

f⁻¹(x) = 1.06x

f⁻¹(4) = 1.06(4) = 4.24

Thus, 4 euros is equivalent to 4.24U.S. dollars

Answer:

426.07 square units

Step-by-step explanation:

Recall that for a triangle whose angles are A,B,C  with corresponding sides a, b, c, the area G of the triangle may be computed as

G = 1/2 ab Sin C

or

G = 1/2 bc Sin A

or

G = 1/2 ac Sin B

Going by this, recall that the sum of angles in a triangle is 180 hence

94 + 26 + K = 180

120 + K = 180

Subtract 120 from both sides

K = 180 - 120

K = 60 degrees

Given that JK = 24 and JL = 41

G = 1/2 * 24 * 41 Sin 60

= 426.07 square units

Answer: The absolute value is -7 and is -7 far away from 0.

Step-by-step explanation:

The two numbers 7 and 7 have a product of 49 which has the least sum.

The biggest (maximum) and smallest (minimum) variables that a function f may have, either in a specific area or throughout its whole domain, are known as its maxima and minima.

Let f and f′ vary in terms of their derivatives. If f ′ (a) = 0 and f ′′ (a) > 0, and is the comparative minimum of f in that case.

S (x, y) = x + y is the sum of the two values in our function to minimize.

S may be rewritten as s in one variable by using the constraint xy = 49:

xy = 49

y = 49 ÷ x

S(x,y) = x+y

s(x) = x + (49 ÷ x)

s'(x) = 1 + (49 ÷ x²)

x² = 49

x = ±√49

x = ±7

Considering that we are discussing positive numbers:

x = 7

The second derivative test allows us to confirm that it is at least:

s'(x) = 1 + (49 ÷ x²)

s''(x) = 98 ÷ \(x^3\)

s''(x) = 98 ÷ \(x^3\) > 0

The second number is obtained by using the requirement that the combination of the two numbers must equal 49:

x = 7

xy = 49

7y = 49

y = 7

The two numbers 7 and 7 have a product of 49 which has the smallest sum.

Answer:

Fraction of females enrolled in the course = 6 / 7

Step-by-step explanation:

Suppose that

Total Number of males = x  

Total Number of females = 6x  

Total Number of Students = 6x + x = 7x  

Now, we have to find the what fraction of the course females candidates constitute.  

Female Fraction = Total Females : Total Students  

Female Fraction = 6x : 7x  

Female Fraction = 6 : 7  

Female Fraction =  6 / 7

So Total number of females enrolled in the course constitute the fraction = 6 / 7

a) The magnitude of Pˉ is P.  b) The direction cosine of Pˉ with respect to the x-axis is 110/P.  c) The directional angle of Pˉ with respect to the z-axis is arctan(60/√(110^2+(-0.58P)^2)).

a) To find the magnitude of vector Pˉ, we use the formula for the magnitude of a vector in three dimensions, which is the square root of the sum of the squares of its components.

b) The direction cosine of a vector with respect to a specific axis is the ratio of the component of the vector along that axis to its magnitude. In this case, the x-component of Pˉ is 110, so the direction cosine with respect to the x-axis is 110 / P.

c) The directional angle of a vector with respect to a specific axis can be found using the arctan function. In this case, we use the y-component and z-component of Pˉ to find the angle between Pˉ and the z-axis.

Therefore, the magnitude of Pˉ is given by P, the direction cosine with respect to the x-axis is cos(θ_x), and the directional angle with respect to the z-axis is θ_z.

By applying the concept of central and extreme scores, it can be concluded that a score of x = 85 would be considered a central score in population 1, and an extreme score in populations 2 dan 3.

A central score is a score that is near the middle of the distribution, while an extreme score is a score that is far out in the tail of the distribution.

In order to determine whether a score of x = 85 is a central score or an extreme score for each of the following populations, we need to look at the distribution of scores in each population.

Overall, whether a score of x = 85 is considered a central score or an extreme score depends on the distribution of scores in the population. If the scores are evenly distributed and x = 85 is near the middle of the distribution, it would be considered a central score. However, if the scores are clustered around a different value and x = 85 is far out in the tail of the distribution, it would be considered an extreme score.
