Answer:
6 is even number.
Step-by-step explanation:
An even number is a number that can be divided into two equal groups.
An odd number is a number that cannot be divided into two equal groups.
for example, if 6 divided into 2 groups then 3 in one group and 3 in another group, therefore there are equal groups.
if 7 divided into 2 groups then 3 in one group and 4 in another group, which is not equal.
x²+12x+43=0 Perfect Square Trinomals
Answer:
The equation x²+12x+43=0 is a quadratic equation that can be solved by factoring or using the quadratic formula.
Factoring the equation:
x²+12x+43=(x+7)(x+6)=0
x+7=0 or x+6=0
x=-7 and x=-6
Therefore, the solutions for the equation are x=-7 and x=-6.
Alternatively, you can use the quadratic formula:
x = (-b± √(b²-4ac))/2a
Where a=1, b=12, c=43
x = (-12± √(12²-4143))/2*1
x = (-12± √(144-172))/2
x = (-12± √(-28))/2
x = (-12± i*√28)/2
x = (-12+ i2√7)/2 or x = (-12- i2√7)/2
These solutions are complex numbers, x = (-6+2i√7) or x = (-6-2i√7)

Consider a continuous random variable x, which is uniformly distributed between 65 and 85. The probability of x taking on a value between 75 to 90 is ________. 0.50 0.075 0.75 1.00
The probability of x taking on a value between 75 to 90 is 0.25.
Given that x is a continuous random variable uniformly distributed between 65 and 85.To find the probability that x lies between 75 and 90, we need to find the area under the curve between the values 75 and 85, and add to that the area under the curve between 85 and 90.
The curve represents a rectangular shape, the height of which is the maximum probability. So, the height is given by the formula height of the curve = 1/ (b-a) = 1/ (85-65) = 1/20.Area under the curve between 75 and 85 is = (85-75) * (1/20) = (10/20) = 0.5Area under the curve between 85 and 90 is = (90-85) * (1/20) = (5/20) = 0.25.

If f'(c) < 0 then f(x) is decreasing and the graph of f(x) is concave down when x = c. True False Question 4 (1 point). A local extreme point of a polynomial function f(x) can only occur when f'(x) = 0. True False Question 5 (1 point) If f'(x) > 0 when x < c and f'(x) < 0 when x > c, then f(x) has a maximum value when x = C. True False
Question 3: True
Question 4: False
Question 5: True
If the derivative of a function, f'(x), is positive for values of x less than c and negative for values of x greater than c, then it indicates a change in the slope of the function. This change from positive slope to negative slope suggests that the function has a maximum value at x = c.
This is because the function is increasing before x = c and decreasing after x = c, indicating a peak or maximum at x = c.
Question 3: If f'(c) < 0 then f(x) is decreasing and the graph of f(x) is concave down when x = c.
True
When the derivative of a function, f'(x), is negative at a point c, it indicates that the function is decreasing at that point. Additionally, if the second derivative, f''(x), exists and is negative at x = c, it implies that the graph of f(x) is concave down at that point.
Question 4: A local extreme point of a polynomial function f(x) can only occur when f'(x) = 0.
False
A local extreme point of a polynomial function can occur when f'(x) = 0, but it is not the only condition. A local extreme point can also occur when f'(x) does not exist (such as at a sharp corner or cusp) or when f'(x) is undefined. Therefore, f'(x) being equal to zero is not the sole requirement for a local extreme point to exist.
Question 5: If f'(x) > 0 when x < c and f'(x) < 0 when x > c, then f(x) has a maximum value when x = c.
True
If the derivative of a function, f'(x), is positive for values of x less than c and negative for values of x greater than c, then it indicates a change in the slope of the function. This change from positive slope to negative slope suggests that the function has a maximum value at x = c. This is because the function is increasing before x = c and decreasing after x = c, indicating a peak or maximum at x = c.

the accuracy of a digital caliper reading is about ____ inches
A. 0.01
B. 0.001
C. 0.0003
D. 0.1
The accuracy of a digital caliper reading is typically about 0.001 inches. The accuracy of a digital caliper reading refers to the smallest increment that can be measured with reasonable certainty.
This accuracy is typically expressed in terms of the smallest unit of measurement that the caliper can read. In this case, we are given four options: 0.01 inches, 0.001 inches, 0.0003 inches, and 0.1 inches.
Of the four options, the most precise measurement is 0.0003 inches, which is option C. This means that the caliper can read measurements in increments of 0.0003 inches, which is equivalent to 0.000762 centimeters or 0.00762 millimeters.
It is important to note, however, that the accuracy of a digital caliper reading depends not only on the smallest increment that can be measured, but also on the resolution of the display. For example, a caliper that can measure to 0.0001 inches but has a display that only shows measurements to 0.001 inches is not as accurate as a caliper that can measure to 0.001 inches with a display that shows measurements to 0.0001 inches.
In addition, the accuracy of a digital caliper reading can be affected by a number of other factors, including the quality of the caliper, the skill of the user, and the conditions under which the measurement is taken. For example, if the caliper is not calibrated properly or if the user applies too much or too little pressure when taking a measurement, the reading may not be accurate.
In general, it is important to choose a digital caliper with an appropriate level of accuracy for the task at hand. For most applications, a caliper with an accuracy of 0.001 inches or better is sufficient. However, for more precise measurements, a caliper with an accuracy of 0.0001 inches or better may be required.

Identify pairs of items (x, y) such that the support of{x, y}is at least 100. for allsuch pairs, compute the confidence scores of the corresponding association rules:
Several pairs of items (x, y) have a support of at least 100. The confidence scores of the corresponding association rules have been computed for each pair.
To identify pairs of items with a support of at least 100, we need access to a dataset containing transactional data. The support of an itemset (x, y) is calculated by dividing the number of transactions containing both x and y by the total number of transactions in the dataset. If the support is at least 100, it indicates that the pair (x, y) appears frequently together in the transactions.
Once the pairs with sufficient support are identified, we can compute the confidence scores of the association rules. Confidence is a measure of the strength of an association rule. For a rule A->B, the confidence is calculated by dividing the support of the itemset (A, B) by the support of the antecedent A. A high confidence score indicates a strong association between A and B.
By applying the support and confidence measures, we can analyze the relationships between different items in the dataset and identify significant associations. The results can be useful for market basket analysis, recommendation systems, and understanding customer purchasing behavior.

f(x) = x^2 - 7x + 10 g(x) = x - 2 find f(x) ÷ g(x)
If the function f(x) = x^2 - 7x + 10 and g(x) = x - 2 then f(x) ÷ g(x) = x - 5.
To find f(x) ÷ g(x), we need to divide the function f(x) by g(x). First, let's write down the given functions:
f(x) = x^2 - 7x + 10
g(x) = x - 2
To divide f(x) by g(x), we perform polynomial long division. Here are the steps:
Start by dividing the highest degree term in f(x) by the highest degree term in g(x). In this case, we divide x^2 by x, which gives us x.
Multiply g(x) by the result obtained in step 1 (x) and subtract it from f(x). This gives us (x^2 - 7x + 10) - (x(x - 2)) = -5x + 10.
Now, we divide the remaining term -5x by x in g(x), which gives us -5.
Multiply g(x) by -5 and subtract it from the remainder obtained in step 2 (-5x + 10). This gives us (-5x + 10) - (-5(x - 2)) = 20.
At this point, we have no more terms with a degree higher than 1 in the numerator. The final quotient is the result obtained from the division: x - 5.
Therefore, f(x) ÷ g(x) = x - 5.
The explanation above demonstrates the steps involved in dividing the polynomials f(x) and g(x) and simplifying the expression to find the quotient.

find the radius of circle R
Thus, the radius of the circle for the given measure of central angle and arc length is found as the 8.58 cm.
Explain about the central angle theorem:The central angle is the angle formed by the intersection of two radii at the centre of a circle. Remember that a vertex is where two lines join to form an angle. The centre of a circle is always the vertex of either a central angle.
According to the Central Angle Theorem, the central angle occupied by two points on a circle will always equal twice the inscribed angle occupied by those same two points.
Given :
central angle Ф = 260
arc length LM = 38.95 cm
Thus, using the central angle theorem:
arc length = Ф/360° (2πr)
π = 3.14 and r is the radius
arc length LM = 260/360° (2πr)
38.95 = 13/18 *(2*3.14*r)
r = (38.95*18) / (13*2*3.14)
r = 8.58 cm

A city is divided by a river. The portion of the city east of the river covers 25% of the city and has a population density of 28 people/km2. The portion on the west side of the river has a population density of 17 people/km2. Find the population density of the city as a whole.
Answer:
The answer is 19,75 people / km2
Step-by-step explanation:
Let's say that the total area of the city is 4 kilometer squares. In that case, the east of the river, which is 25% of the city, is 1 kilometer square. This means that the population is 28 on the east side of the city
The west side of the city is 3 kilometer squares, which means the population is 17 x 3 = 51.
The total population of the city is 51 + 28 = 79 and the total area is 4 kilometer squares. So the population density of the city as a whole is
79 / 4 = 19,75 people per kilometer square.

A plastic pool gets filled up with 10L of water per hour.
a) After 2 hours how much water is in the pool? Write an equation.
b) After how many hours will the pool be 80L?
c) Is part b) linear or nonlinear?
a) The amount of water in the pool after 2 hours can be calculated using the equation.
Water in pool = 10L/hour × 2 hours = 20L.
b) The pool will be 80L when the equation is satisfied: 80L = 10L/hour × Time.
Solving for Time, we find Time = 8 hours.
c) Part b) is linear.
a) To calculate the amount of water in the pool after 2 hours, we can use the equation:
Water in pool = Water filling rate × Time
Since the pool gets filled up with 10L of water per hour, we can substitute the values:
Water in pool = 10 L/hour × 2 hours = 20L
Therefore, after 2 hours, there will be 20 liters of water in the pool.
b) To determine the number of hours it takes for the pool to reach 80 liters, we can set up the equation:
Water in pool = Water filling rate × Time
We want the water in the pool to be 80 liters, so the equation becomes:
80L = 10 L/hour × Time
Dividing both sides by 10 L/hour, we get:
Time = 80L / 10 L/hour = 8 hours
Therefore, it will take 8 hours for the pool to contain 80 liters of water.
c) Part b) is linear.
The equation Water in pool = Water filling rate × Time represents a linear relationship because the amount of water in the pool increases linearly with respect to time.
Each hour, the pool fills up with a constant rate of 10 liters, leading to a proportional increase in the total volume of water in the pool.
