Answer:
24
Step-by-step explanation:
If there are 6 pitchers on the Sluggers and they make up 25% or 1/4th of the team, you can just add 6 (1/4th) to itself to 3 more times to gett 100% or 4/4ths.
6+6+6+6 (or 6×4) is 24.
Simplify (4s^5t*-7/−2s^-2t^4)^3. Write your answer using only positive exponents
This simplified form of given expression is: 21952s¹⁵t³/(-8s⁶t¹²) = 21952 / -8 *s¹⁵t³ / s⁶t¹² = 2744 / -1 * s⁹t⁻⁹
What is expression?An expression or mathematical expression is a finite collection of symbols that is well-formed according to context-dependent norms. In mathematics, an expression is a phrase that has at least two numbers or variables and at least one arithmetic operation. Addition, subtraction, multiplication, or division are all examples of math operations. An expression in mathematics is a collection of numbers, variables, and functions (such as addition, subtraction, multiplication or division etc.) Expressions and phrases are similar in structure.
Here,
Now, we can multiply this result by the original expression raised to the power of 3:
(4s⁵t⁻⁷/−2s⁻²t⁴)³ * (1/(-8s⁶t¹²)) = (4s⁵t⁻⁷)³ / (-8s⁶t¹²)
Finally, we'll simplify the numerator by raising 4s⁵t-7 to the power of 3:
(4s⁵t-7)³ = (4s⁵t)³ * (-7)³ = 64s¹⁵t³ * 343 = 21952s¹⁵t³
Putting it all together, we get the abbreviated version of the given expression: 21952s¹⁵t³/(-8s⁶t¹²) = 21952 / -8 *s¹⁵t³ / s⁶t¹² = 2744 / -1 * s⁹t⁻⁹

Two different workers are producing a specialized part for a machine. The number of parts produced per hour by the workers are as follows:
Worker A: 5, 4, 4, 6, 7, 5, 6, 3
Worker B: 4, 8, 1, 9, 2, 9, 4, 3
Both workers averaged 5 parts per hour. Which worker has the higher variance and standard deviation?
Worker B has the higher variance and standard deviation than Worker A.
What is standard deviation?Standard deviation in statistics, typically denoted by σ, is a measure of variation or dispersion (refers to a distribution's extent of stretching or squeezing) between values in a set of data. The lower the standard deviation, the closer the data points tend to be to the mean (or expected value), μ.
Given,
The number of parts produced per hour by the workers are as follows:
Worker A: 5, 4, 4, 6, 7, 5, 6, 3
Worker B: 4, 8, 1, 9, 2, 9, 4, 3
Average μ = 5
Variance = σ² = Σ(xi - μ)²/N
Variance for first worker
= [(5 - 5)² + (4 - 5)² + (4 - 5)² + (6 - 5)² + (7 - 5)² + (5 - 5)² + (6 - 5)² + (3 - 5)²]/8
= [0² + -1² + -1² + 1² + 2² + 0² + 1² + -2²]/8
= [1 + 1 + 1 + 4 + 1 + 4]/8
= 12/8

= [(4 - 5)² + (8 - 5)² + (1 - 5)² + (9 - 5)² + (2 - 5)² + (9 - 5)² + (4 - 5)² + (3 - 5)²]/8
= [-1² + 3² + -4² + 4² + -3² + 4² + -1² + -2²]/8

The terminal side of angle θ intersects the unit circle in the first quadrant at x=17/23. What are the exact values of sinθ and cosθ?
The exact value of sinθ = 15.5/23
And, The exact value of cosθ = 17/23
What is Circle?The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.
We have to given that;
The terminal side of angle θ intersects the unit circle in the first quadrant at x=17/23.
We know that;
The given parameters are represented as;
⇒ (x, y) = ( cos θ , sin θ )
Here, x = 17/23
Hence, We get;
⇒ cos θ = 17/23
Now, Using the following trigonometry identity;
⇒ cos²θ + sin²θ = 1
⇒ (17/23)² + sin²θ = 1
⇒ 289/529 + sin²θ = 1
⇒ sin²θ = 1 - 289/529
⇒ sin²θ = 529 - 289 / 529
⇒ sin²θ = 240/529
⇒ sin θ = √240/529
⇒ sinθ = 15.5 / 23
Thus, The exact value of sinθ = 15.5/23
And, The exact value of cosθ = 17/23

The length of a rectangle is 10yd less than three times the width, and the area of the rectangle is 77yd^2 . Find the dimensions of the rectangle.
Let's let w = the width of the rectangle. If the length is 10 yards less than 3 times the width, then the length is 3w - 10.
How do we find the area? Length times width, right?
So, we have w(3w - 10) = 77. Distributing, we get 3w2 - 10w = 77.
We need to put it all on one side, so we subtract 77 from both sides.
3w2 - 10w - 77 = 0
Now, we have to factor the left side. To do this, we multiply 3(-77) = -231. What are two factors of -231 that add up to -10? How about -21 and 11? -21(11) = -231 and -21 + 11 = -10.
This may not be how you are taught, but we are now going to split -10w into -21w + 11w and plug that into our equation.
Sooooo, now we have 3w2 - 21w + 11w - 77 = 0
Next, we are going to look at the first two terms, 3w2 - 21w. What is common between the two? 3w. Factoring out 3w, we get 3w(w - 7).
Now, the second two terms, 11w - 77. What is common? 11. Factoring out 11, we get 11(w - 7).
Putting all of that together, we now have 3w(w - 7) + 11(w - 7) = 0.
I can explain why and make it more confusing, so I'll just tell you that, since the w - 7 is the same in both parentheses, we keep that as one set of parentheses and combine what's in front into a second set of parentheses.
So, we have (w - 7)(3w + 11) = 0
Lastly, for the left side to equal 0, then either w - 7 and/or 3w + 11 has to equal 0, right?
We pull each out and set them equal to 0.
w - 7 = 0
w = 7
If we plug in 7, we get (7-7)(3(7) + 11) = (0)(21+11) = 0(32) = 0, which is what we want.
3w + 11 = 0
3w = -11
w = -11/3
If we plug -11/3 into the same equation, we'd get 0, again what we want. However, we can't have a negative length! Therefore, -11/3 is out as an answer.
Our width is 7. Since the length is 3w - 10, we plug in 7 and get 3(7) - 10 = 21 - 10 = 11.
Let's check. Length times width = 7(11) = 77. Check!

Select the two real roots of the polynomial function
S(r) = 5 +44 - 137³-10² - 12r + 72.
Or=-6; r = 2
Or=2; r = 6
Or=-6; T=-2
Or= -1; r = 6
Or= -2; r = 1
The real roots of the polynomial function are (a) r = -6 and r = 2
How to determine the real roots of the polynomial functionFrom the question, we have the following polynomial function that can be used in our computation:
s(r) = r^5 + 4r^4 - 13r^3 - 10r^2 - 12r + 72
At the real roots of the polynomial function, the following must be true
s(r) = 0
Using the above as a guide, we have the following:
Next, we test the options
Option (a)
s(-6) = (-6)^5 + 4(-6)^4 - 13(-6)^3 - 10(-6)^2 - 12(-6) + 72 = 0
s(2) = (2)^5 + 4(2)^4 - 13(2)^3 - 10(2)^2 - 12(2) + 72 = 0
See that s(-6) and s(2) have the values of 0
Hence, the real roots are s = -6 and s = 2

Step-by-step explanation:
For a moving object, the force acting on the object varies directly with the object's acceleration. When a force of 20 N acts on a certain object, the acceleration of the object is 5 /ms2. If the force is changed to 16 N, what will be the acceleration of the object? /ms2
The acceleration of the object when the force on the object changes to 16 N is 4 m/s²
What is the basic formula for force?The second law of motion by Newton says that the force is equal to the change in momentum per change in the time. For a constant mass, force equals the mass times acceleration, i.e. F = m x a.
Given here: A force acting on an object.
We know, The formula for force states that the force is equal to mass that is multiplied by the acceleration.
Thus we have the equation as F=m.a
Now in case 1 we have
20=m×5
m=4 kg
Again in case 2 we have
16 = 4×a
a=4 ms⁻²

a) The leash is 12.2 ft long.
b) The diagonal is 7.1m
c) The altitude is 6.1 in
How to find the length of the leash?
We can see a right triangle here, where the leash is the hypotenuse of that triangle.
Using the Pythagorean's theorem we can write:
leash = √( (10ft)² + (7ft)²)
leash = 12,2 ft
8) Remember that for a square of side length S, we have:
perimeter = 4*S
diagonal = √2*S
We know that the perimeter is 20 meters, then:
20m = 4*S
S = 20m/4 = 5m
Then the diagonal is:
D = √2*5m = 7.1m
9) For an equilateral triangle of sidelength S, the altitude is:
A = √( S² - (S/2)²)
In this case the side length is 7 inches, then:
A = √( (7in)² - (7in/2)²)
A = 6.1 in

The perimeter of a square must be greater than 96 inches but less than 124 inches. Find the range of possible side lengths that satisfy these conditions. (Hint: The
perimeter of a square is given by P= 4s, where a represents the length of a side).
Express your answer in interval notation. Use decimal form for numerical values.
The range of the side of the square is 24 to 31. The interval notation is (24,31).
What is interval notation?
An interval on a number line can be represented using interval notation. It is a method of representing subsets of the real number line, in other words.
Given that, the perimeter of a square must be greater than 96 inches but less than 124 inches.
Inequality form is
96 < P < 124
Where P is the perimeter.
The perimeter of a square is P = 4s, where s is the length of the side.
Putting P = 4s in 96 < P < 124
96 < 4s < 124
Divide by 4:
24 < s < 31
The interval notation is (24,31).
