Is 3 x 1/2 greater than 5?

Answer: Option (C): L′(−1, 2)

Step-by-step explanation:

To reflect the preimage over y = -2, we can use the formula for reflecting a point (x, y) over a horizontal line y = b:

(x, y') = (x, 2b - y)

In this case, the horizontal line is y = -2, so b = -2.

So we can find the image coordinate of L' as follows:

L' = (-1, 2(-2) - (-6)) = (-1, 4)

Therefore, the image coordinate of L' after reflecting the preimage over y = -2 is L'(-1, 4). So the answer is option (c): L′(−1, 2).

Removing the electric car from the data set will reduce the standard deviation as the extreme value of 112 mpg is taken out, resulting in a decrease in the spread of the data. The interquartile range (IQR) will also be affected as the extreme outlier is taken out, will decrease the spread of the data in the boxplot.

The electric car with a rating equivalent to 112 miles per gallon is an extreme outlier, which means it is very far from the rest of the data. Therefore, removing this outlier from the data set will decrease the variability and, consequently, decrease the standard deviation. The extreme outlier with the rating equivalent to 112 miles per gallon is outside of the whiskers of the boxplot, which means it is beyond the range of the middle 50% of the data. Therefore, removing this outlier from the data set will decrease the spread of the data in the boxplot and, consequently, decrease the IQR.

Step-by-step explanation:

Ema found the surface area of a cone as:

\(S.A = \pi(14^2) + \pi(14)(29)\)

Surface Area of a Cone \(S.A.=\pi r^2+\pi rl\)

Therefore:

Radius, r =14 units

Slant Height, l = 29 Units

(B)The diameter of the cone is 28 units.

SInce Diameter =Radius X 2

Diameter = 14 X 2= 28 Units

(C)The base area of the cone is \(196\pi$ units^2.\)

Base Area of a Cone \(=\pi r^2\)

Since r=14 Units

Base Area = \(=\pi 14^2=196\pi $ square units\)

(D)The lateral area is the product of pi, the radius(r), and the slant height(l).

There is a slight possibility of 0.000240 that  5 card hand contains a four-of-a-kind, where the four-of-a-kind rank is a face card.

Total possible outcomes=⁵²C₅

                                        = 2598960

P( 4-of-a-kind) = ¹³C₁ * ⁴C₄

                        = 13

P( choosing one card from the rest of the deck) = ⁴⁸C₁

                                                                                 =48

P( 4-of-a-kind card with one different card)

= desired outcome / total number of outcomes.

= (13* 48) / 2598960

= 624/2598960

= 0.000240

Therefore, we get that the probability is 0.0240% .

There are many questions and problems for which efficient algorithms exist, but there are also many others for which no efficient algorithm is currently known, and some for which it has been proven that no algorithm can exist.

The field of computer science and mathematics known as computational complexity theory studies which problems can be solved by algorithms and how efficient those algorithms are. The theory classifies problems into different complexity classes based on the resources required to solve them, such as time, space, or the number of processors.

There are certain classes of problems for which efficient algorithms are known to exist. For example, sorting a list of numbers or searching for an item in a database can be done in polynomial time, which means that the time required to solve the problem grows at most as a polynomial function of the size of the input.

On the other hand, there are problems for which no efficient algorithm is currently known. One famous example is the traveling salesman problem, which asks for the shortest possible route that visits a set of cities and returns to the starting point. While algorithms exist to solve this problem, they have an exponential running time, meaning that the time required to solve the problem grows exponentially with the size of the input, making them infeasible for large inputs.

There are also problems for which it has been proven that no algorithm can exist that solves them efficiently. For example, the halting problem asks whether a given program will eventually stop or run forever. It has been proven that there is no algorithm that can solve this problem for all possible programs.

In summary, there are many questions and problems for which efficient algorithms exist, but there are also many others for which no efficient algorithm is currently known, and some for which it has been proven that no algorithm can exist.

In an effort to reduce wait times in the emergency room. Eighty patients were polled at random by the investigating committee. And, the upper-bound 95% confidence interval is found to be 1.64.

For small sample numbers or unidentified changes, the t-distribution is used in statistics to calculate the significance of population parameters.

Given sample mean \(\overline{X}\) is 1.5 hours, sample size n is 80, and sample standard deviation s is 0.7 hours. Then, the standard error for the mean is,

\(\begin{aligned}SE_x&=\frac{s}{\sqrt{n}}\\&=\frac{0.7}{\sqrt{80}}\\&=0.07826\end{aligned}\)

The degree of freedom is given by, df = n-1 = 80-1 = 79.

From the t-distribution table, \(t_{\alpha/2, 79}=1.7735\)

Then, the upper-bound 95% confidence interval is calculated as,

\(\begin{aligned}\overline{X}+t_{\alpha,(n-1)}\frac{s}{\sqrt{n}}&\geq \mu\\&=\overline{X}+t_{0.08, 79}\frac{s}{\sqrt{n}}\\&=1.5+1.7735\left(\frac{0.7}{\sqrt{80}}\right)\\&=1.5+1.7735(0.07826)\\&=1.5+0.13879\\&=1.63879\\&\approx1.64\end{aligned}\)

The mean age of the combined distribution of both men and women in the course is 20.47 years

What is average/mean ?

The middle number, which is determined by dividing the sum of all the numbers by the total number of numbers, is the average value in mathematics. When determining the average for a set of data, we add up all the values and divide this sum by the total number of values.

Mean age of men , M = 20.7 years

Mean age of Women , W = 20.2 years

Percentage of Men = 54%

Percentage of Women = 46%

Recall, :

Mean, μ = np

The mean age of men in the distribution = (20.7 × 54%) = 11.178 years

The mean age of women in the distribution = (20.2 × 46%) = 9.292 years

The mean age of the combined distribution is :

11.178 + 9.292 = 20.47 years

Therefore, the mean age of the combined distribution is 20.47 years

The four basic properties of exponents are the negative exponent property, the product of powers property, the quotient of powers property, and the power of a power property.

The properties of exponents are a set of rules that allow us to simplify terms that contain exponents.

Negative exponent property states that when a negative exponent is present, the base and the exponent are switched and the sign of the exponent is changed. For example,  x-2 = 1/x2.

The product of powers property states that when two terms with the same base are multiplied, the exponents are added together. For example, x3 x4 = x7.

The quotient of powers property states that when two terms with the same base are divided, the exponents are subtracted. For example, x6/x2 = x4.

The power of a power property states that when a term with an exponent is raised to another power, the exponents are multiplied. For example, (x3)2 = x6.

These properties can be used to simplify expressions that contain exponents. For example, the expression (−2m−2????4) 3 can be simplified using the power of a power property by multiplying the exponents. The expression simplifies to −2m−6????12.

The probability that a five-card poker hand does not contain the queen of hearts is 47/52.

We have been given that,

Total card to choose = 5

Total cards in a deck = 52

We need to find the probability that a five-card poker hand does not contain the queen of hearts.

The total ways of choosing 5 cards from a deck of 52 cards = \(^{52}C_5\)

The number of queens of hearts in a deck = 1

The number of cards excluding queens of hearts = 52 - 1

                                                                                  = 51

The total ways of choosing 5 cards from 51 cards = \(^{51}C_5\)

Now we find the required probability.

\(\Rightarrow P= ^{51}C_5 \times ^{52}C_5\\\\\Rightarrow P=\frac{51!}{5!(51-5)!} ~\times \frac{52!}{5!(52-5)!}\\\\\Rightarrow P=\frac{47}{52}\)

Therefore, the probability that a five-card poker hand does not contain the queen of hearts is 47/52.
