Calculate the area and circumference of a circle with diameter 8cm
Tell me if the photo below is the answer for this question
Answers
Answer: approximately 25.13 centimeters.
Step-by-step explanation: If the diameter of a circle is 8cm, then the radius is half of that, which is 4cm. We can use this information to calculate the area and circumference of the circle as follows:
Area of circle = π * r^2
= π * 4^2
= π * 16
= 16π
≈ 50.27 cm^2 (rounded to two decimal places)
Circumference of circle = 2π * r
= 2π * 4
= 8π
≈ 25.13 cm (rounded to two decimal places)
Therefore, the area of the circle is approximately 50.27 square centimeters and the circumference is approximately 25.13 centimeters.

Elizabhet debe preparar carapulcra para 32 personas si se basa en la receta que se muestra que cantidad necesitara de cada ingrediente carapulcra 8 porciones un medio de papa seca un medio kg de carne de chancho 1 cebolla grande 3 cucharadas de aji panca un entero un medio cucharadas de ajos molidos 1 cucharada de sal
Answers
Step-by-step explanation:
Para hacer las porciones para 32 personas, multiplique cada cantidad de ingrediente por 4 ya que la receta proporciona 8 porciones y 8 * 4 = 32
Papa seca = \(\frac{1}{2} *4\)
= 2 papas secas
Cerdo = \(\frac{1}{2} *4\)
= 2 kg de carne de cerdo
Cebollas = 1 * 4
= 4 cebollas grandes
Aji panca = 3 * 4
= 12 cucharadas de aji panca
Ajo molido = \(1\frac{1}{2} *4\)
= \(\frac{3}{2} *4\)
= 6 cucharadas de ajo molido
Sal = 1 * 4
= 4 cucharadas de sal
if m, p, and t are distinct positive prime numbers, then m3pt has how many different positive divisors greater than 1 ?
Answers
There are 15 different positive divisors (greater than 1) for the number m³pt. Here m, p, and t are distinct prime numbers. This is obtained by the prime factorization method.
How to find the number of positive factors for a number?The following are the steps to find the number of positive factors of a number:
Step 1: Find the L.C.M of the number by using the prime factorization method. For example: consider the number 24. Then, its prime factorization is as follows:
24 = 2 × 2 × 2 × 3
Step 2: Same bases should be added in powers. So, the factors we can write as
24 = 2³ × 3¹
Step 3: To find the number of positive factors of the number, the exponents of the prime factors is multiplied by adding 1.
I,e., N = (3 + 1)(1 + 1) = 4 × 2 = 8.
So, there are 8 factors for the number 32. They are 1, 2, 3, 4, 6, 8, 12, and 24.
Calculation:It is given that, m, p, and t are distinct positive prime numbers.
Then, the number of positive divisors greater than 1 for the number m³pt are
m³× p × t
Since m, p, and t are prime factors, we can multiply their power by adding 1 to them. I.e.,
N = (3 + 1) (1 + 1) (1 + 1) = 4 × 2 × 2 = 16
So, there are a total of 16 factors for the given number (including 1). So, the number of factors greater than 1 is 16 - 1 = 15.
Therefore, there are 15 different positive divisors greater than 1 for the number having prime factors as m³pt.

jokes are listed in a magazine, where one is written by a female author. If the order in which these jokes are told makes a difference in terms of how they are received, how many ways can they be delivered if a joke by a man is told first?
Answers
Answer: Let's assume that there are "m" jokes written by male authors and "f" jokes written by female authors, such that m + f = total number of jokes in the magazine.
If a joke by a man is told first, there are (m - 1)! ways to arrange the remaining m - 1 jokes written by male authors and f! ways to arrange the jokes written by the female author. The total number of ways the jokes can be delivered is (m - 1)! * f!.
So, the answer is (m - 1)! * f! ways to deliver the jokes if a joke by a man is told first.

Answers
The probability that he misses the train today is 0.135 or 13.5%.
P(Class runs late)=30%=0.30
P(Miss train ∣ Class runs late)=45%=0.45
General multiplication rule:
P(A and B)=P(A)×P(B ∣ A)
Using the general multiplication rule, we then obtain (and using that the student always catches his train if the class ends on time) :-
P( Miss train)=P( Miss train and Class runs late)=P(Class runs late)×P(Miss train ∣ Class runs late)
= 0.30×0.45
= 0.135

Least common multiple (LCM)
The smallest multiple that two or more numbers have in common.
Find the prime factors of the given numbers:
2, 3 and 5 are prime numbers.Prime factorization of 15 = 3 × 5Prime factorization of 30 = 2 × 3 × 5Prime factorization of 45 = 3² × 5To find the LCM of each set of given numbers, find the product of only those factors with the highest powers.
A: LCM of 2, 3, 15 and 30
List the prime factors of each number:
2 = 23 = 315 = 3 × 530 = 2 × 3 × 5So the factors are 2, 3 and 5.
As the highest power of each factor is one, the LCM is 2 × 3 × 5 = 30.
B: LCM of 2, 5, 15 and 30
List the prime factors of each number:
2 = 25 = 515 = 3 × 530 = 2 × 3 × 5So the factors are 2, 3 and 5.
As the highest power of each factor is one, the LCM is 2 × 3 × 5 = 30.
C: LCM of 2, 5, 15 and 45
List the prime factors of each number:
2 = 25 = 515 = 3 × 545 = 3² × 5So the factors are 2, 3 and 5.
As the highest power of 2 and 5 is one, and the highest power of 3 is two, the LCM is 2 × 3² × 5 = 90.
D: LCM of 3, 5, 15 and 45
List the prime factors of each number:
3 = 35 = 515 = 3 × 545 = 3² × 5So the factors are 3 and 5.

The curves f(x) = x² - 2x - 5 and g(x) = 4x + 11 intersect at the point (-2,3). Find the angle of intersection, in radians on the domain 0 < t < T. Round to two decimal places.
Answers
To find the angle of intersection between two curves, we can use the derivative of the curves and the formula for the angle between two lines. The angle of intersection can be found by calculating the arctangent of the difference of the slopes of the curves at the point of intersection.
at the point of intersection (-2, 3) and then calculate the angle.
The derivative of f(x) = x² - 2x - 5 is f'(x) = 2x - 2.
The derivative of g(x) = 4x + 11 is g'(x) = 4.
At the point (-2, 3), the slopes of the curves are:
f'(-2) = 2(-2) - 2 = -6
g'(-2) = 4
The difference in slopes is g'(-2) - f'(-2) = 4 - (-6) = 10.
Now, we can calculate the angle of intersection using the arctangent:
Angle = arctan(10)
Using a calculator, the value of arctan(10) is approximately 1.47 radians.
Therefore, the angle of intersection between the curves f(x) = x² - 2x - 5 and g(x) = 4x + 11 on the given domain is approximately 1.47 radians.

(car sales) of the cars sold during the month of july, 87 had air conditioning, 99 had automatic transmission, and 73 had power steering. 8 cars had all three of these extras. 24 cars had none of these extras. 24 cars had only air conditioning, 64 cars had only automatic transmissions, and 35 cars had only power steering. 9 cars had both automatic transmission and power steering. how many cars had exactly two of the given options?
Answers
Cars with exactly two options = Total cars - Cars with none or one option - Cars with all three options. 8 cars had exactly two of the given options during the month of July.
To determine the number of cars that had exactly two of the given options (air conditioning, automatic transmission, and power steering), we can follow these steps:
1. Find the total number of cars sold in July.
2. Subtract the number of cars with none, one, or all three options to get the number of cars with exactly two options.
Step 1: Find the total number of cars sold in July
- 24 cars had none of the extras
- 24 cars had only air conditioning
- 64 cars had only automatic transmission
- 35 cars had only power steering
- 8 cars had all three extras
Total cars = 24 + 24 + 64 + 35 + 8 = 155 cars
Step 2: Subtract the number of cars with one or all three options
- 87 cars had air conditioning
- 99 cars had an automatic transmission
- 73 cars had power steering
- 8 cars had all three extras
Total cars with at least one option = 87 + 99 + 73 - 8 = 251 cars
Now, subtract the number of cars with none or one option from the total number of cars to find the number of cars with exactly two options:
Cars with exactly two options = Total cars - Cars with none or one option - Cars with all three options
Cars with exactly two options = 155 - (24 + 24 + 64 + 35) - 8 = 155 - 147 = 8 cars
Therefore, 8 cars had exactly two of the given options during the month of July.

The U.S. Senate consists of 100 senators, with 2 from each of the 50 states. There are 50 Democrats in the Senate. A committee of size 10 is formed, by picking a random set of senators such that all sets of size 10 are equally likely. a) Find the expected number of Democrats on the committee. b) Find the expected number of states represented on the committee (by at least one senator) c) Find the expected number of states such that both of the state's senators are on the committee.
Answers
Note that based on probabilities,
The expected number of Democrats on the committee is 5.
The expected number of states represented on the committee is 26.
The expected number of states such that both of the state's senators are on the committee is 9.09.
How is this so ?a) The probability that a randomly chosen senator is a Democrat is 50/100 = 1/2.
So, the expected number of Democrats on a committee of size 10 is
1/2 * 10 = 5.
b) The minimum number of states that can be represented on a committee of size 10 is 2, and the maximum numberis 50.
The expected number of states representedon the committee is the average of these two values, which is (2 + 50)/ 2 = 26.
c) There are 50 states, and each state has 2 senators. So, there are a total of 100 pairs of senators.
The probability that a randomly chosen pair of senators both belong to the same state is 50/100 * 49/99
= 1/11.
The expected number of states such that both of the state's senators are on the committee is 100 * 1/11 = 9.09.

TRUE/FALSE.We can use the normal distribution to approximate the sampling distribution of the average (x ¯) for a small sample (n<30) even if our sample has clear outliers.
Answers
The given statement, "We can use the normal distribution to approximate the sampling distribution of the average (\(\bar X\)) for a small sample (n<30) even if our sample has clear outliers." is false.
What is sample distribution?Several random samples of a predetermined size are taken from the same population to generate a sampling distribution, which is a sort of probability distribution. You can better understand how a sample statistic fluctuates from sample to sample by using these distributions.
The given statement is false because when the sample size is small (n < 30) and the data have clear outliers, the normal distribution may not be a suitable approximation for the sampling distribution of the average (\(\bar X\)). In such cases, the presence of outliers can significantly affect the distribution, causing it to deviate from a normal distribution.
For small samples with outliers, it is generally recommended to use alternative methods or non-parametric tests that do not assume a specific distribution. These methods take into account the non-normal nature of the data and provide more robust and reliable results.

f) None of the above.
Answers
The probability that 5 hearts are chosen when 7 cards are drawn from a well-shuffled deck of 52 playing cards is option (d) 0.00000962.
Step 1: Determine the total number of ways to choose 7 cards from a deck of 52 playing cards, which can be calculated using the combination formula: C(52, 7) = 52! / (7! * (52 - 7)!), where "!" denotes the factorial.
Step 2: Determine the number of ways to choose 5 hearts from the deck. There are 13 hearts in a standard deck, so we can calculate the number of ways to choose 5 hearts from 13: C(13, 5) = 13! / (5! * (13 - 5)!).
Step 3: Calculate the probability by dividing the number of favorable outcomes (choosing 5 hearts) by the total number of possible outcomes (choosing 7 cards from the deck): P(5 hearts) = C(13, 5) / C(52, 7).
Step 4: Evaluate the probability numerically using a calculator or math software, and the result is approximately 0.00000962.
Therefore, the correct answer is option (d) 0.00000962.

Write a linear equation given the two points: (-3, -9) and (4, -2)
Answers
y = mx + b
where m is the slope of the line, and b is the y-intercept.
To find the slope, we can use the formula:
m = (y2 - y1) / (x2 - x1)
where (x1, y1) and (x2, y2) are any two points on the line.
Using the given points (-3, -9) and (4, -2), we can calculate the slope:
m = (-2 - (-9)) / (4 - (-3)) = 7/7 = 1
Now that we have the slope, we can use one of the given points to find the y-intercept. Let's use the point (-3, -9):
y = mx + b
-9 = 1*(-3) + b
-9 = -3 + b
b = -6
Therefore, the equation of the line that passes through the points (-3, -9) and (4, -2) is:
y = x - 6
