de los animales que hay en un corral la mitad son gallinas, la quinta parte patos, la novena parte pavos y 510 son pollos ¿cuantos animales hay en el corral?
The number of animals there are in the corral is 1020.
We are given that Number of chicken=510
This is a word problem that can be solved by using fractions and proportions.
Let x be the total number of animals in the corral. Then, according to the problem, we have:
x/2 = 510 (half are chickens) x/5 = ? (a fifth are ducks) x/9 = ? (a ninth are turkeys)
To find the total number of animals, we need to find a common denominator for the fractions and add them up. The least common multiple of 2, 5, and 9 is 90, so we multiply each fraction by 90 to get:
45x/90 = 45 * 510 (half are chickens) 18x/90 = ? (a fifth are ducks) 10x/90 = ? (a ninth are turkeys)
Adding up the fractions, we get:
(45x + 18x + 10x)/90 = 73x/90
This is the fraction of animals that are chickens, ducks, or turkeys. To find the total number of animals, we need to divide both sides by 73/90, which is equivalent to multiplying by 90/73. We get:
x = (73x/90) * (90/73) x = x
Therefore, the total number of animals in the corral is x.
To find the value of x, we can use the equation x/2 = 510 and solve for x. We get:
x/2 = 510 x = 510 * 2 x = 1020
Therefore, by unitary method the answer will be 1020.

You want to be able to withdraw $50,000 from your account each year for 15 years after you retire.
You expect to retire in 30 years.
If your account earns 7% interest, how much will you need to deposit each year until retirement to achieve your retirement goals?
To achieve your retirement goal of withdrawing $50,000 each year for 15 years after retirement, while earning 7% interest, you will need to deposit approximately $3,671.95 each year for the next 30 years. This calculation is based on the concept of annuity, which takes into account the future value of money and the time value of money. By consistently depositing this amount over the next 30 years, your account will accumulate enough funds to support your retirement withdrawals.
Choose the missing step in the given solution to the inequality −2x − 14 > −4 + 3x.
−2x − 14 > −4 + 3x
−5x − 14 > −4
_______________
x < −2
−5x < 10
−5x > −28
x < 2
−5x > 10
The missing step is −5x > −28. This is obtained by adding 14 to both sides of the inequality. Then, to get x < −2, we divide both sides by −5 and reverse the direction of the inequality sign.
Find the missing angle. Enter only a value. Round to the nearest degree (whole number). Hint: use inverse trig. Your answer should be an odd number. Thank you!
The missing angle is approximately 67 degrees. To find it, we used the fact that the sum of the angles in a triangle is 180 degrees and calculated the angle opposite the base using inverse tangent.
What is angle?An angle is the measure of the space between two intersecting lines, rays, or line segments, given in degrees or radians, often denoted by the symbol θ.
What is tangent?Tangent is a trigonometric function that relates the ratio of two sides of a right triangle: the length of the opposite side over the length of the adjacent side of a given angle.
According to the given information:
The angle theta is the angle between the hypotenuse and the base of a right triangle. We can use the formula for the tangent of an angle to find theta:
tan(θ) = opposite/adjacent
In this case, the opposite side is the height of the triangle (9), and the adjacent side is the base of the triangle (21). So:
tan(θ) = 9/21
tan(θ) = 0.42857...
Using the inverse tangent function ([tex]tan^{-1}[/tex]) on both sides:
θ = [tex]tan^{-1(0.42857...)}[/tex]
θ = 23.8171...
Rounding to the nearest degree gives us an odd number:
θ6 ≈ 23 degrees
Now, to find the missing angle, we can use the fact that the sum of the angles in a triangle is 180 degrees. We know that one angle is 90 degrees (it's a right triangle), and we just found the angle opposite the base (theta). So:
180 - 90 - θ = missing angle
180 - 90 - 23 ≈ 67
Therefore, the missing angle is approximately 67 degrees.

Use integers for A, B, and C.
A line passes through point −9, 7 and has a slope of −43, the equation of the line in the =+AxByC form is 43x + y = -380.
To write the equation of a line in the form of Ax + By = C, we need to find values for A, B, and C.
We know that the line passes through the point (-9, 7) and has a slope of -43. We can use the point-slope form of the equation to find the equation of the line:
y - y1 = m(x - x1)
Where m is the slope and (x1, y1) is a point on the line.
Substituting the values we know:
y - 7 = -43(x + 9)
Expanding and rearranging:
y - 7 = -43x - 387
43x + y = -380
Thus, the equation of the line in the =+AxByC form is 43x + y = -380.

Several months ago while shopping, I was interviewed to see whether or not I'd be interested in signing up for a subscription to a yoga app, I fall into the
category of people who have a membership at a local gym, and guessed that, like me, many people in that category would not be interested in the app. My
friend Rachel falls in the category of people who do not have a membership at a local gym, and I was thinking that she might like a subscription to the app.
After being interviewed, I looked at the interviewer's results. Of the 99 people in my market category who had been interviewed, 19 said they would buy a
subscription, and of the 107 people in Rachel's market category, 24 said they would buy a subscription.
Assuming that these data came from independent, random samples, can we conclude, at the 0.01 level of significance, that the proportion p, of all mall
shoppers in my market category who would buy a subscription is less than the proportion P₂ of all mall shoppers in Rachel's market category who would a

(e) Can we conclude that the proportion of mall shoppers in my market category who would buy a

OYes ONO
(a) The Null Hypothesis (H₀): The proportion of mall shoppers in my market category who would buy a subscription is greater than or equal to the proportion in Rachel's market category (P₂). Conversely, Alternatvie Hypothesis H₁ insinuates that this proportion is less.
How to explain the hypothesis(b) In order to evaluate the legitimacy of these speculations; we have decided to employ the z-test statistic.
(c) In order to determine the test statistic: we will use the formula:
z = (p₁ - p₂) / √(p(1-p)(1/n₁ + 1/n₂))
where p = (x₁ + x₂) / (n₁ + n₂), where x₁ and x₂ denote the number of successes (or people who said they would purchase a subscription) in each sample, whereas n₁ and n₂ represent the sample sizes, respectively.
According to our data, we received the following: x₁ = 19, n₁ = 99, x₂ = 24, and n₂ = 107. Taking into consideration the aforementioned variables, we obtained p₁= 0.191, p₂= 0.224, and P = 0.208 for the equation above. Therefore,
z= (0.191 - 0.224)/√(0.208(1-0.208)(1/99+1/107)) ≈ -1.238
(rounded to three decimal places).
(d) For the single tailed test at 0.01 level of significance, the critical value generated by the z-test was -2.33.
(e) As a result of the calculated test statistic(-1.238) being greater than the produced critical value (-2.33); we cannot refute the null hypothesis. In other words, with an alpha of 0.01, we cannot conclude that the ratio of mall buyers in my market sector wanting to buy a subscription is less than that of the ones from Rachel's.

A town of 500,000 people is struck by a devastating epidemic. The number of people infected after t days is modeled by
500,000/1+499e^-1.617t
How many people will be infected 4 days after the breakout? Round to the nearest whole number.
Answer: The following formula determines the total number of infected people after t days:
500,000 / (1 + 499e^(-1.617t))
We can enter t = 4 into the algorithm to determine the total number of affected 4 days after the outbreak and then assess:
Step-by-step explanation:
500,000 / (1 + 499e^(-1.617(4))) = 500,000 / (1 + 499e^(-6.468))
= 500,000 / (1 + 499(0.00155))
= 500,000 / (1 + 0.77445)
= 500,000 / 1.77445
When this is rounded to the closest whole number, we obtain:
281,580
Therefore, four days after the outbreak, about 281,580 people will be infected.

12. The scatterplot of the data below models what type of correlation?
Negative correlation.
Explanation:1. Concepts.First of all, let's define the term "correlation" in math functions.
Correlation is a numeric value that expresses how strong the relation is between two variables. It also tells us how one functions affects the other. It can be calculated.
There are three classifications for correlations:
• Positive correlation. This type of correlation indicates that when a variable increases in value, the other variable follows the same behavior.
• Negative correlation. This correlation, on the other hand, indicates that when a variable increases, the other variables does the opposite, it decreases.
• No correlation. This is when one variable has no effect over the other.
Check the attached image to see how these correlations look like in a graph.
2. Analyzing the questionOn this question we are given a graph with several points on it. As you can tell, the more we move to the right on the "x" axis, the lower the points are. Therefore, as "x" increases, "y" decreases. This is a clear example of a negative correlation graph.
tyrone saved $24of the $60 he earened mowing lawns. what ercent of his earnings did he save
To find out the percentage of Tyrone's earnings that he saved, we need to divide the amount he saved by his total earnings and then multiply by 100 to convert the result into a percentage.
The amount that Tyrone saved is $24, and his total earnings are $60.
So,
Percentage of earnings saved = (Amount saved / Total earnings) x 100
= ($24 / $60) x 100
= 0.4 x 100
= 40%
Therefore, Tyrone saved 40% of his earnings by putting aside $24 from the $60 he earned mowing lawns.

The remaining person will take 4 days to finish the work.
What is work?Work has a completely different connotation in science than it does in ordinary life. Every time labour is performed, energy is transmitted, as shown by the definition of work in physics.
Let's assume that each man can do the whole job in "x" days.
According to the problem, three men can do the job in 10 days, so their combined work rate is:
3/x = 1/10
Solving for x, we get x = 30.
This means that one man can do the job in 30 days.
After three days, one man leaves, so only two men are left to complete the remaining job. They have already worked for 3 days, so the remaining work is:
(2/3) * (7/10) = 14/30
This means that two men can do the remaining work in 14 days.
After another three days, one more man leaves, so only one man is left to complete the remaining job. They have already worked for a total of 6 days (3 days + 3 days), so the remaining work is:
(1/3) * (4/10) = 4/30
This means that one man can do the remaining work in 4 days.

ABCDEF form a regular hexagon with centre O.−−→OA=10a−−→OB=10bX is the midpoint of BC. Y is the point on AB extended such that AB : BY = 3 : 2. Express: (i) the vector −−→EX in terms of a and/or b. (ii) the vector −−→XY in terms of a and/or b.
Results:
(i) The vector −→EX in terms of a and/or b, →X = 1/2 (10b →OB + 10a →OA)
(ii) The vector −−→XY in terms of a and/or b→XY = →Y - 1/2 (10b →OB + 10a →OA)
How to express the vector?(i) We can use the midpoint formula, which states that the midpoint of a line segment is the average of the coordinates of its endpoints to express the vector −→EX in terms of a and/or b.
Since X is the midpoint of BC, we can express X as the average of the coordinates of B and C:
→X = 1/2 (→B + →C)
Since B is located at 10b units in the direction of vector →OB from O, and C is located at 10a units in the direction of vector →OA from O, we can express →B and →C in terms of a and b:
→B = 10b →OB
→C = 10a →OA
Substituting these values into the expression for →X, we get:
→X = 1/2 (10b →OB + 10a →OA)
(ii) To express the vector −→XY in terms of a and/or b, we can use the given ratio AB: BY = 3: 2.
Since AB is a vector from A to B, we can express it as →AB = →B - →A.
Substituting the expressions for →B and →A, we get:
→AB = 10b →OB - →OA
Since AB: BY = 3: 2, we can express BY as 2/3 of AB:
→BY = 2/3 (→AB)
Substituting the expression for →AB, we get:
→BY = 2/3 (10b →OB - →OA)
Finally, we can express →XY as the vector from Y to X, which is the opposite of →X to →Y:
→XY = →Y - →X
Substituting the expressions for →X and →Y, we get:
→XY = →Y - 1/2 (10b →OB + 10a →OA)

How many ways are there to arrange the letters in the word GRIFFIN?
Step-by-step explanation:
There are 720 ways to arrange the letters in the word GRIFFIN.
To see why, we can use the formula for permutations of a set with n elements, which is n! (n factorial).
The word GRIFFIN has 7 letters, so we have:
7! = 7 x 6 x 5 x 4 x 3 x 2 x 1 = 5040
However, since the letters in GRIFFIN are not all unique (there are 2 Fs and 2 Is), we need to divide by the number of ways the repeated letters can be arranged. This is the product of their factorials:
2! x 2! = 4
So the final answer is:
7! / (2! x 2!) = 5040 / 4 = 720
Examples of different arrangements of the letters in GRIFFIN are:
- FIGRINF
- IRGIFNF
- NGRIFFI
- IFRIGNF
- GFRINIF
- NRIGIFF
- FFIRIGN
And so on, for a total of 720 possible arrangements.

How many four digit numbers can be formed from the digits 1,3,5,7,8 and 9 where a digit is used at most once?
A.if the numbers must be even?
B.if the numbers are less thsn 3000?
i need detail explanation
Part(A),
The given digits can be used to create 300 even four-digit numerals.
Part(B),
These four-digit numbers come in a set of 60.
A. If the numbers must be even:
The units digit has six options: 2, 4, 6, 8, or 0. The units digit cannot be 1, 3, 5, 7, or 9, as they are all odd numbers.
Use any of the last five digits; for the hundreds digit, use any of the last four digits. The tens digit can be represented by any of the last three digits.
The sum of the digits 1, 3, 5, 7, 8, and 9 yields the following number of even four-digit numbers:
5 × 5 × 4 × 3 = 300
The given digits can be used to create 300 even four-digit numerals.
A. If the sum is less than three thousand:
Four-digit numbers are less than 3000, hence a thousand digits must be 1. There are five possibilities for the units digit (since we cannot use 1 or 3).
With each digit appearing just once or twice, the total number of four-digit numbers that may be made that are fewer than 3000 is:
5 × 4 × 3 = 60
There are 60 such four-digit numbers.
