The smallest two-digit prime number that is not an emirp is 11.

An emirp is a prime number that, when its digits are written in reverse order, becomes another prime number. In this way, 73 is an emirp because when its digits are reversed, we get 37, which is also a prime number.

To answer this question, we must examine each of the two-digit prime numbers and verify whether or not they are emirps.

Let's begin by listing all of the two-digit prime numbers:

11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97.

We must now test each of the above prime numbers to see whether they are emirps by reversing their digits and then testing if the new number is also prime.

We do not need to examine the primes in reverse order since, if a number is a two-digit prime, its reverse will also be a two-digit number.

Let's start by checking whether 11 is an emirp or not by reversing its digits.11 reversed becomes 11, which is the same number. Since 11 is a prime number, it is not an emirp.

Therefore, 11 is the smallest two-digit prime number that is not an emirp.

This statement is "The binomial probability distribution is always negatively skewed" false because the shape of the binomial distribution depends on the values of n and p, where n is the sample size and p is the probability of success on a single trial.

If p is close to 0 or 1, the distribution will be skewed. However, if p is close to 0.5 and n is large enough, the distribution can be approximated by a normal distribution, which is symmetric.

In general, the binomial distribution tends to be right-skewed when p < 0.5 and left-skewed when p > 0.5. The degree of skewness also depends on the sample size. As the sample size increases, the distribution becomes more symmetric, regardless of the value of p.

Therefore, it is incorrect to say that the binomial distribution is always negatively skewed. The shape of the distribution depends on the values of n and p.

Rap music is generally more popular with young blacks than young whites, during the 80s-90s when rap was becoming more popular with artists such as 2pac, BIG, Dr. Dre, etc they were more popular among young blacks than whites

Answer:

1. (4, 3) and (8, 6)

2. Yes. The line shows a direct proportion. y = 0.75x

Try (20, 15) in the equation.

15 = 0.75(20)

15 = 15

Point (20, 15) works in the equation, so point (20, 15) is on the line.

3.

Let x = 100.

y = 0.75x

y = 0.75 × 100

y = 75

Since x = 100 gives y = 75, point (100, 75) is on the line.

4.

Let x = 90

y = 0.75x

y = 0.75 × 90

y = 67.5

For x = 90, y must be 67.5. Since this point is (90, 68), it is not on the line.

The root of the graph of f(x) =(x - 5)3(x + 2)2 touches the x-axis at -2,5

(x - 5)^3 has a power of 3 which is an ODD number. An ODD power means that the graph will cross through the x-axis.

(x + 2)^2 has a power of 2 which is an EVEN number. An EVEN power means that the graph will touch the x-axis.

Given: Function f(x) is (x - 5)3(x + 2)2

If a curve touches the x-axis then f(x) = 0

⇒ (x - 5)3(x + 2)2 = 0.

But if ab = 0 ⇒ either a = 0 or b = 0 or both zero.

⇒ (x - 5)3 = 0 and (x + 2)2 = 0

⇒ (x - 5) = 0 and x + 2 = 0

The area of parallelogram with "one angle of a parallelogram is 120 degrees, and two consecutive sides have lengths of 8 inches and 15 inches" is 60√3 inch².

A quadrilateral with the opposing sides parallel is called a parallelogram (and therefore opposite angles equal). A parallelogram with all right angles is known as a rectangle, and a quadrilateral with equal sides is known as a rhombus. A parallelogram is a geometric shape with sides that are parallel to one another in two dimensions. It is a type of polygon with four sides (also known as a quadrilateral) in which each parallel pair of sides is the same length.

Here,

A parallelogram has adjacent angles that add up to 180 degrees.

Since one angle of parallelogram is 120°.

240+2x=360

2x=120

x=60

The other will be 60°

The area of parallelogram= lh

l=15 inch

h=b(sin 60°)

=8*√3/2

h=4√3 inch

area of parallelogram= 15*4√3

= 60√3 inch²

The parallelogram's area is 60√3 inch² when "one angle of a parallelogram is 120 degrees, and two consecutive sides have lengths of 8 inches and 15 inches."

In economics, the SRAS curve represents the short-run aggregate supply, which depicts the relationship between the price level and the quantity of output supplied in the short run. There are two versions of the SRAS curve: one with flexible prices and one with sticky prices. The Hayekian Triangle is a graphical representation of the interplay between time, capital, and production in an economy.

AA decrease in patience, within the context of the Hayekian Triangle, implies a shift in time preferences and can have implications for resource allocation.

In economics, the SRAS curve illustrates the short-run aggregate supply, which shows the relationship between the overall price level and the quantity of output supplied in the short run. The SRAS curve with flexible prices is upward sloping, indicating that as prices rise, firms are willing and able to produce more output due to higher profitability. On the other hand, the SRAS curve with sticky prices is relatively flat, indicating that firms are unable or unwilling to adjust prices immediately in response to changes in demand or production costs. This stickiness can be caused by factors such as contracts, menu costs, or market imperfections.
The Hayekian Triangle, named after economist Friedrich Hayek, is a graphical representation of the interplay between time, capital, and production in an economy. It illustrates the trade-offs and decisions made by individuals and businesses based on their time preferences and the availability of capital goods. The triangle consists of three vertices: time, consumption goods, and production goods. It represents the process of using time and capital goods to transform resources into consumption goods.
A decrease in patience, within the context of the Hayekian Triangle, implies a shift in time preferences. When individuals and businesses become less patient, they place greater emphasis on immediate consumption rather than saving or investing in production goods. This shift in time preferences can have implications for resource allocation. If there is a decrease in patience, it may lead to reduced savings and investment, resulting in a lower capital stock and potentially lower future productivity and economic growth. It highlights the importance of balancing present consumption with future-oriented investments to maintain sustainable economic development.

Answer:

m∠DBC = 86°

Step-by-step explanation:

Find the variable, x.  First, combine like terms. Like terms are terms with the same amount of the same variable:

3x + 4x + 67 + 50 = 180

(7x) + (117) = 180

Next, isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. PEMDAS is the order of operations, and stands for:

Parenthesis,

Exponents (& Roots)

Multiplications

Divisions

Additions

Subtractions

~

First, subtract 117 from both sides of the equation:

7x + 117 (-117) = 180 (-117)

7x = 180 - 117

7x = 63

Next, divide 7 from both sides of the equation:

(7x)/7 = (63)/7

x = 63/7 = 9

x = 9

Next, plug in 9 for x in the angle DBC:

m∠DBC = 4x + 50

             = 4(9) + 50

             = 36 + 50

             = 86°

m∠DBC = 86°

We divide this inequality at each of the signs and solve for the two boundaries of x.

We then use the other inequality and solve for x:

This last result, x > -9, is included in the previous result, as x has to be greater than -4.

We can test the result for x = 0, which should satisfy both equations:

If x is less or equal than -4, the right side of the inequality won't be satisfied.

If x is less or equal than -9, both sides of the inequality are not satisfied.

C. Yes, there is an outlier at 110. This means that one person's age was 110, which is 25 years older than the next closest age.

Step-by-step explanation:

An outlier is a data point that sticks out like a sore thumb. It's so different from the rest of the data that it makes you wonder if it's a mistake or a miracle. One way to spot an outlier is to use the 1.5IQR rule, where IQR stands for interquartile range. The interquartile range is the gap between the third quartile (Q3) and the first quartile (Q1) of the data. The 1.5IQR rule says that any data point that is more than 1.5*IQR above Q3 or below Q1 is an outlier.

In this case, the first quartile (Q1) is 75, the third quartile (Q3) is 85, and the interquartile range (IQR) is 10. So, any data point that is more than 1.5*10 = 15 above 85 or below 75 is an outlier. The only data point that does this is 110, which is 25 above 85. That means 110 is an outlier.

What does this outlier mean in this situation? It means that one person who came to the senior center that afternoon was way older than the rest of the folks. The average age of the visitors was not changed by this outlier, since it was just one out of 12 data points. But, the outlier does mess up the range and the standard deviation of the data, making them bigger than they would be without the outlier.

The square root of the given expression√49 is equal to ±7.

As given in the question,

Given expression is equal to √49.

Let the square root of 49 be equal to the variable x we get,

x = √49

Write factors of 49 in form of prime numbers we get,

49 = 7 × 7

⇒ x = √ 7 × 7

⇒ x = √7²

Apply law of exponent ( mᵃ )ᵇ = mᵃᵇ we get,

here m = 7 , a = 2 and b = 1/2

⇒ x = ( 7² )^1/2

⇒ x = ( 7 )^( 2 × 1/2 )

⇒ x = ( 7 ) ¹

Any number raise to one is equal to number itself.

⇒ x = 7

Therefore, the square root of the given expression √49 is given by 7.

(a) The closed-loop system transfer function can be obtained using the formula:

Gcl(s) = G(s) / [1 + G(s)H(s)]

where G(s) is the plant transfer function and H(s) is the feedback transfer function. In this case, G(s) = Gy(s) and H(s) = Gc(s) = Kp + Kd*s. Substituting these values and simplifying, we get:

Gcl(s) = Gy(s) / [1 + KpGy(s) + KdGy(s)*s]

= 105 / [s^2 + 20s + (105Kp + 2010Kd)s + 105Kd]

(b) The closed-loop static gain is the value of Gcl(s) when s = 0. Substituting s = 0 in the expression for Gcl(s), we get:

Gcl(0) = 105 / (105Kd)

To obtain a closed-loop static gain of 0.95, we need:

0.95 = 105 / (105Kd)

Solving for Kd, we get:

Kd = 105 / (0.95 * 105) = 1.1053

(c) For the system to be critically damped, we need the poles to be real and repeated. This means that the discriminant of the characteristic equation should be zero. The characteristic equation of the closed-loop system is:

s^2 + 20s + (105Kp + 2010Kd)s + 105Kd = 0

Substituting the values of Kd and equating the discriminant to zero, we get:

(105Kp + 20101.1053)^2 - 41051.10531 = 0

Solving for Kp, we get:

Kp = -166.1326 or -23.8674

Since we cannot have a negative value for the proportional gain, we choose:

Kp = -23.8674

Substituting this value and Kd = 1.1053 in the expression for Gc(s), we get:

Gc(s) = -23.8674 + 1.1053*s

Therefore, the PD controller that achieves a closed-loop static gain of 0.95 and critical damping is:

Gc(s) = -23.8674 + 1.1053*s
