Answer:
∠ O = 72°
Step-by-step explanation:
the inscribed angle R is half the measure of its intercepted arc NQ , then
arc NQ = 2 × 36° = 72°
the central angle O is equal to the measure of the arc that subtends it , so
∠ O = arc NQ = 72°

Please help me
61mm has to be converted to cm.
Simply divide by 10 [ 10mm = 1cm ]
61 mm = (61/10) = 6.1 cm
5.5 + 6.1 = 11.6cm
OR...
Convert 5.5cm to mm by multiplying by 10
5.5cm = (5.5×10) = 55mm
55+61 = 116mm
116mm = (116/10) = 11.6cm
The answer for this question is 11.6 cm or 116 mm.
You need to convert either millimeter to centimeter or vice versa
1 cm = 10 mm
converting 5.5 cm to mm :
5.5 X 10 = 55 mm
Now, add both the values of millimeter:
55 + 61 = 116 mm
If we need answer in centimeter
we can convert 116 mm into cm
116/10 = 11.6 cm

For a moving object, the force acting on the object varies directly with the object's acceleration. When a force of 10 N acts on a certain object, the acceleration of the object is 5 /ms2. If the force is changed to 14 N, what will be the acceleration of the object?
The acceleration of the object when a force of 14 N acts on it will be 7 m/s².
We can use the proportionality relationship between force and acceleration to solve this problem. The relationship can be expressed as:
F = k a
where F is the force, a is the acceleration, and k is a constant of proportionality.
We are given that the force and acceleration are directly proportional, so we can set up a proportion using the given information:
10 N / 5 m/s² = 14 N / a
Solving for a, we can cross-multiply and simplify:
10 N * a = 5 m/s² * 14 N
a = (5 m/s² * 14 N) / 10 N
a = 7 m/s²
Therefore, the acceleration of the object when a force of 14 N acts on it will be 7 m/s².

Two congruent cylinders each have radius 8 inches and height 3 inches. The radius of one cylinder and the height of the other are both increased by the same nonzero number of inches. The resulting volumes are equal. How many inches is the increase
Let's denote the increase in both the radius and the height of the cylinders as 'x' inches.
The volume of a cylinder can be calculated using the formula V = πr²h, where V is the volume, r is the radius, and h is the height.
For the first cylinder (with original radius 8 inches and height 3 inches), the volume is given by V₁ = π(8)²(3) = 192π cubic inches.
For the second cylinder (with increased radius and height), the volume is given by V₂ = π(8 + x)²(3 + x).
Given that the resulting volumes are equal, we can set up the following equation:
V₁ = V₂
192π = π(8 + x)²(3 + x)
Canceling out the π from both sides, we have:
192 = (8 + x)²(3 + x)
Expanding the equation:
192 = (64 + 16x + x²)(3 + x)
192 = 192 + 48x + 16x² + 3x + x²
0 = 16x² + 51x
Simplifying the quadratic equation:
16x² + 51x = 0
x(16x + 51) = 0
Setting each factor equal to zero:
x = 0 (nonzero number of inches)
16x + 51 = 0
16x = -51
x = -51/16
Since we're looking for a nonzero increase, the increase is x = -51/16 inches.
Note: It's important to check the validity of the negative value for 'x' since it represents an increase. In this case, the negative value implies a decrease rather than an increase. Therefore, the increase in both the radius and the height is 0 inches.

How much commission will the salesperson earn by selling a couch for $495?
Answer:
The salesperson will get $27.23
Step-by-step explanation:
Given that:
Commission of salesperson = 5.5% of selling price
Selling cost of couch = $495
Commission amount = 5.5% of 495
Commission amount = \(\frac{5.5}{100}*594\)

in the logistic model for population growth dp/dt = p(12-3p), what is the carrying capacity of the population P (t) a. 12b. 1/4c.4 d. 3
The correct answer for the carrying capacity of the population in the logistic model with the equation dp/dt = p(12-3p) is 4.
In the logistic model, the carrying capacity represents the maximum population size that an environment can sustain in the long term. In the equation dp/dt = p(12-3p), the carrying capacity is represented by the value at which the growth rate of the population is zero.
To find this value, we set the right-hand side of the equation to zero and solve for p:
0 = p(12-3p)
0 = p(4-p)
This equation has two solutions: p = 0 and p = 4. The solution p = 0 represents the population size when the growth rate is zero, but it is not the carrying capacity since the population would not survive at this size.
The solution p = 4 represents the carrying capacity, which is the maximum population size that the environment can support in the long term.
Therefore, the carrying capacity of the population in the logistic model with the equation dp/dt = p(12-3p) is 4.

Step-by-step explanation: has to do with ratios and proportionalities. 3/8 is going to equal b/32. B = to number of basil leaves. 32/8= 4. 4x3=12.
Answer:
Twelve.
Step-by-step explanation:
This scenario can be interpreted by the ratio 3:8, with 3 being the amount of basil leaves and 8 being the amount of tomatoes. If there were 32 tomatoes in the sauce, then there would have been 12 basil leaves.

Given the trinomial, what is the value of the coefficient b in the factored form? 2x2 4xy − 48y2 = 2(x by)(x − 4y)
In the factored form 2x^2 + 4xy - 48y^2 = 2(x - 4y)(x - 4y), the value of the coefficient b is 4.
In the factored form of the trinomial 2x^2 + 4xy - 48y^2 = 2(x - by)(x - 4y), the value of the coefficient b can be determined by comparing the factors of the trinomial with the factored form.
We see that in the factored form, the binomial (x - by) represents the first term and the binomial (x - 4y) represents the last term. The coefficient b corresponds to the term involving both x and y, which is the middle term 4xy in the original trinomial.
Comparing the middle term of the original trinomial (4xy) with the factored form, we can deduce that the coefficient b is equal to 4.
Therefore, in the factored form 2x^2 + 4xy - 48y^2 = 2(x - 4y)(x - 4y), the value of the coefficient b is 4.

Determine whether the lines CD and EF in the image are parallel for the given angle measures.
By applying the consecutive interior angles theorem, lines CD and EF in the image are not parallel for the given angle measures.
What are parallel lines?Parallel lines can be defined as two (2) lines that are always the same (equal) distance apart and never meet.
Given the following data:
m∠BPG = 139°
m∠GPC = 95°
m∠BQF = 110°
What is the consecutive interior angles theorem?The consecutive interior angles theorem states that when two (2) parallel lines are cut through by a transversal, the interior angles that are formed are congruent and each pair of the consecutive interior angles is supplementary.
By applying the consecutive interior angles theorem, we have:
m∠BPG + m∠GPC = 180°
139° + 95° ≠ 180° (not parallel).
m∠BPG + m∠BQF = 180°
139° + 110° ≠ 180° (not parallel).
m∠GPC + m∠BQF = 180°
95° + 110° ≠ 180° (not parallel).

By using the fact that the sum of the interior angles of a triangle must be 180°, we will get:
x = 11m∠B = 108°m∠B = 36°m∠D = 36°How to find the value of x?Remember that the sum of the internal angles of a triangle is always equal to 180°, then we can write:
m∠B + m∠C + m∠D = 180°
Then:
13x - 35 + 5x - 19 + 2x + 14 =180
20x -40 = 180
20x = 180 + 40
20x = 220
x = 220/20
x = 11
Now that we know the value of x, we can find the measures of the angles.
m∠B = (13x- 35)° = (13*11 - 35)° = 108°
m∠B = (5x - 19)° = (5*11 - 19)° = 36°
m∠D = (2x + 14)° = (2*11 + 14)° = 36°

which of the following statements do you believe are true? in a normal distribution - a) approximately 70% of the values are within one standard deviation from the mean, b) twenty-seven percent of the values are between one and two standard deviations from the means. c) 2.1% of the values are between -2 and -3 standard deviations from the mean. d) .1% of the values are 3 of higher standard deviations from the mean. e) all the alternatives are correct. f) none of the alternatives are correct. g) only a and b are correct. h) only c and d are correct.
The correct statement is "only a and c are correct" so option g is the answer.
The statement that is true in a normal distribution is "approximately 70% of the values are within one standard deviation from the mean" (a), and "2.1% of the values are between -2 and -3 standard deviations from the mean" (c).
These statements are true because of the properties of a normal distribution, also known as a Gaussian distribution or bell curve. In a normal distribution, the majority of values cluster around the mean, with fewer and fewer values as you move further away from the mean.
The statement "twenty-seven percent of the values are between one and two standard deviations from the mean" (b) is not true, as the correct percentage is approximately 27.7% (68-95-99.7 rule).
The statement "0.1% of the values are 3 or higher standard deviations from the mean" (d) is also not true, as the correct percentage is approximately 0.3%.

He selects a sample of 28 local high school students and records how much time they spend studying per week to compare it to the regional average. John does not know the standard deviation of the underlying population, but he is confident that the population is normally distributed because other studies indicate that study times are normally distributed, and graphs of his sample data indicate normality.
To test if the mean weekly study time from his sample differs from 21.1 hours, John needs to use a one-sample t-test because the population standard deviation is unknown and the sample size is less than 30. The one-sample t-test is a statistical hypothesis test used to determine if there is a significant difference between the mean of a sample and a known or hypothesized population mean when the standard deviation of the population is not known.
It tests whether the sample mean is significantly different from the hypothesized population mean, taking into account the sample size and the sample standard deviation. The null hypothesis, in this case, is that there is no significant difference between the mean weekly study time of the local high school students and the regional average of 21.1 hours.
The alternative hypothesis is that there is a significant difference between the two means. John will calculate the t-test statistic using the sample mean, sample standard deviation, and sample size, and compare it to the critical t-value for his chosen level of significance (usually 0.05). If the t-test statistic is greater than the critical t-value, he can reject the null hypothesis and conclude that there is a significant difference between the mean weekly study time of the local high school students and the regional average of 21.1 hours

the overall classification of the series is mixed: some of the terms are convergent and some are divergent. Therefore, the series is conditionally convergent.
It appears that there might be some errors or missing information in the provided series. However, I can provide you with a general guideline on how to determine if a series is absolutely convergent, conditionally convergent, or divergent.
1. Absolutely convergent: A series ∑a_n is absolutely convergent if the series ∑|a_n| converges. To check this, you can use various tests like the Ratio Test, Root Test, or the Comparison Test.
2. Conditionally convergent: If the series ∑a_n converges, but the series ∑|a_n| diverges, then the series is considered conditionally convergent. This usually applies to alternating series, where the terms switch signs.
3. Divergent: If the series ∑a_n does not converge, it is considered divergent. Divergence can be checked using the Divergence Test. If the limit of the sequence a_n as n approaches infinity is not equal to zero, then the series is divergent.
The series (-1)n n4 + 1 is divergent because it does not approach a finite limit as n approaches infinity.
The series (-1)nn n2+ 1 is also divergent because it does not approach a finite limit as n approaches infinity.
The series (n)2+ 4 3n is convergent because it approaches zero as n approaches infinity.
The series (-1)k+ 1 * 1 * 4 * 7 ...(3k - 2) k:2k is divergent because it does not approach a finite limit as k approaches infinity.
The series [(2n+ 1)2 5n2]n is convergent because it approaches a finite limit as n approaches infinity.
Therefore, the overall classification of the series is mixed: some of the terms are convergent and some are divergent. Therefore, the series is conditionally convergent.
