The object will travel 639.36 yards in one minute.
Formula: Yards = Feet x 0.3333
The question is asking how many yards an object will travel in one minute when it is moving at a constant rate of 32 feet per second.
We can use the formula above to calculate the number of yards the object will travel in one minute. We know that the object is traveling at a rate of 32 feet per second. To find the number of yards traveled in one minute, we need to multiply 10.6667 yards per second by 60 seconds in a minute. Therefore, in one minute (60 seconds), the object will travel 32 x 60 = 1920 feet. We can now use the formula to convert this to yards: Yards = 1920 x 0.3333 = 639.36 yards. Therefore, the object will travel 639.36 yards in one minute.

what does the value of the sample correlation coefficient indicate about the relationship between the admit rate () and the -yr grad. rate ()?
The sample correlation coefficient, is represented as r, measures the strength of correlation and direction of the linear relationship between two variables. It ranges from -1 to 1. The closer the coefficient is to -1, the stronger the negative correlation, the closer it is to 1, the stronger makes the positive correlation reach towards its closer and the closer towards to the expectancy to 0, the weaker the correlation.
The correlation coefficient does not indicate the cause and effect relationship between the variables, just the association between them.
A positive correlation tells us that as one variable increases with respective its the other variable also increases, and a negative correlation means that as one variable increases with respective to its the other variable decreases.
So, the value of the sample correlation coefficient between the rates of admit and the -yr grad rate . rate can indicate if these variables are positively or negatively done as correlated and how strong is this correlation occurs.

the screamers are coached by coach yells at. the screamers have $12$ players, but two of them, bob and yogi, refuse to play together. how many starting lineups (of $5$ players) can coach yells lot make, if the starting lineup can't contain both bob and yogi? (the order of the $5$ players in the lineup does not matter; that is, two lineups are the same if they consist of the same $5$ players.)
The total number of starting lineups (of 5 players) can coach yells lot make, if the starting lineup can't contain both bob and yogi is 672.
What is starting lineups?An official list of the players who will take part in the event when the game starts is known as a starting lineup in sports. The players who are in the starting lineup are frequently referred to as starters, while the rest are known as bench players or replacements.
Case 1: Bob starts (and Yogi doesn't). In this case, the coach must choose 4 more players from the 10 remaining players (remember that Yogi won't play, so there are only 10 players left to select from). Thus there are 10C4 lineups that the coach can choose.
⇒ ¹⁰C₄ = 10!/4!(10-4)! = 10!/4!6!
⇒ ¹⁰C₄ = (10*8*9*7)/(4*3*2*1)
⇒ ¹⁰C₄ = 210
Case 2: Yogi starts (and Bob doesn't). As in Case 1, the coach must choose 4 more players from the 10 remaining players. So there are 10C4 lineups in this case.
⇒ ¹⁰C₄ = 210
Case 3: Neither Bob nor Yogi starts. In this case, the coach must choose all 5 players in the lineup from the 10 remaining players. Hence there are 10C5 lineups in this case.
⇒ ¹⁰C₅ = 10!/5!(10-5)! = 10!/5!5!
⇒ ¹⁰C₅ = (10*8*9*7*6)/(5*4*3*2*1)
⇒ ¹⁰C₅ = 252
To get the total number of starting lineups, we add the number of lineups in each of the cases:
Case 1 + Case 2 + Case 3
= 210 + 210 + 252 = 672
The total number of starting lineups (of 5 players) can coach yells lot make, if the starting lineup can't contain both bob and yogi is 672.

solve the given initial-value problem. d2x dt2 + ω2x = f0 sin ωt, x(0) = 0, x '(0) = 0
The solution to the given initial-value problem is x(t) = c1(e-ωt - eωt) = 2c1 sin ωt
The given initial-value problem is a second-order differential equation: d2x dt2 + ω2x = f0 sin ωt, x(0) = 0, x '(0) = 0
First, we can solve the homogeneous equation d2x dt2 + ω2x = 0 using the method of characteristic equation. The characteristic equation is r2 + ω2 = 0, which has two solutions r1 = -ω, r2 = ω.
The general solution to the homogeneous equation can be expressed as:
x(t) = c1e-ωt + c2eωt
Next, we can solve the non-homogeneous equation d2x dt2 + ω2x = f0 sin ωt. Since the right-hand side of the non-homogeneous equation has a sinusoidal form, we can use the method of variation of parameters to solve it.
The particular solution can be expressed as:
x(t) = A sin ωt + B cos ωt
By substituting the initial conditions, we can get:
A = 0, B = 0
Therefore, the solution to the given initial-value problem is:
x(t) = c1e-ωt + c2eωt
The constant c1 and c2 can be determined by the initial conditions:
x(0) = c1 + c2 = 0
x'(0) = -ωc1 + ωc2 = 0
Therefore, c1 = -c2 and c1 + c2 = 0.
Hence, the solution to the given initial-value problem is:

Joaquin would have 9, 612 different locker combinations if he could repeat a number, but not use the same number twice in a row.
What is the combination?
In simple words, combination involves the selection of objects or things out of a larger group where order doesn't matter. The formula for combination helps to find the number of possible combinations that can be obtained by taking a subset of items from a larger set.
If none of the numbers can be repeated, Joaquin can choose from a total of 22 numbers (0 through 21), and he needs to select three of them for his locker combination. This is a classic example of a combination problem, as the order in which he chooses the numbers does not matter. The number of ways to choose three numbers from a set of 22 without repetition is given by the formula for combinations:
C(22,3) = 22! / (3!(22-3)!) = 222120/(321) = 2310
So, Joaquin can choose from 2310 different locker combinations if none of the numbers can be repeated.
The name "combination lock" is appropriate because it refers to the process of combining numbers in a specific order to open the lock. In this case, the order of the numbers selected does not matter.
If Joaquin could repeat a number, but not use the same number twice in a row, the number of mathematical combinations are possible is given by the formula for permutations:
A(22,3) = 222120 = 9, 612
Hence, Joaquin would have 9, 612 different locker combinations if he could repeat a number, but not use the same number twice in a row.

The probability that in the next game of serenity bowls, her score will be between 183 and 218 is 73.14%
Given that,
Mean = 195
Standard deviation = 14
Thus, the probability between 183 and 218 is the ρ value of z when x = 195

so, x = 218
z = 218-195/14 = 1.64
when x = 183
z = 183-195/14= -0.85
Thus, z value is 1.64 then the probability is 0.94950 and when z value is -0.85 then the probability is 0.21886

a) The velocity and position functions are given as follows:
Velocity: v(t) = sin(t).Position: s(t) = -cos(t) + 3.b) The particle is at rest when: t = kπ, k = ± 1, ± 2, ± 3, ...
How to obtain the functions?The acceleration function for this problem is defined as follows:
a(t) = cos(t).
The velocity function is the integral of the acceleration function, hence it is given as follows:
v(t) = sin(t).
(as the integral of cos(t) is sin(t).)
The particle will be at rest when:
v(t) = 0.
Hence:
sin(t) = 0
t = arcsin(0)
t = kπ, k = ± 1, ± 2, ± 3, ...
The position function is the integral of the velocity function, hence it is given as follows:
s(t) = -cos(t) + 3.
As:
The integral of the sine function is the negative cosine function.The initial position of 3 represents the constant of integration.More can be learned about functions at https://brainly.com/question/24808124

The people who are interviewed constitute a convenience sample.
If the survey company is interviewing anyone who is available in the shopping mall without using any systematic method for selecting the participants, it would be considered a convenience sample.
In a convenience sample, the sample is selected based on ease of access to the participants, and it may not be representative of the entire population. This type of sampling can lead to bias in the sample, as the views of people who happen to be available in the mall at the time may not be representative of the views of the entire population.

1. A store offers a discount of 40% off any one regular-price item. The price paid after this discount is represented by s(2). Employees also receive 10% off any purchases; the price paid after this discount is
represented by e(z). Which of the following represents the composite function of applying the employee discount first, and the store discount second?
Oe(s(z)=0.04z
Oe(s(z))=0.54z
Os(e(z))=0.54z
Os(e(z)) = 0.04z
A function that depends on another function is referred to as a composite function.
What is composite function?A function that depends on another function is referred to as a composite function. When one function is inserted into another, a composite function is produced. For instance, f(g(x)) is the composite function created when x in f is replaced with g(x) (x). You can interpret f(g(x)) as "f of g of x." Replace the rightmost function with the middle function, then this with the leftmost function to find a composite function made up of three functions. For instance, if g(x)=x2, f(x)=3x+1, and h(x)=1/x, h(g(f(x))=1/(3x+1)2 is the result.Let's say the price of an item is $1
Scenario #1 - 40% off $1 = 40 cents OFF
The discounted price = 60 cents
Now the 10% off of 60 cents
60-6 = 54 cents.
Scenario #2 - 10% of $1
The discounted price = 10 cents
100(cents) - 10 = 90 cents
Now the 40% off of 90 cents
90-36 = 54 cents
Let's try another value to confirm
Let's say the price of an item is $2
Scenario #1 - 40% off $2 = 80 cents OFF
200-80= 120 = $1.20
Now the 10% off of $1.20
120-12= 108 = $1.08
Scenario #2 - 10% off $2 = 20 cents OFF
200-20 = 180= 1.80
Now the 40% off of $1.80
180-72 = 108 = 1.08
The complete question is,
A store offers a discount of 40 off any one regular-priced item. employees also get 10% off any purchases. in which order should the discounts apply so that the employee pays the least amount?
A. Employee discount then store discount
B. They are both the same
