A new computer graphics company employs 10 programmers. The company decides to expand into digital animation and needs to transfer 3 of the programmers into the new department. How many different combinations of 3 programmers can be chosen to transfer to the new department?
A. 3
B. 30
C. 120
D. 840
Answers
There are 120 different combinations of 3 programmers that can be chosen to transfer to the new department
How to determine the ways of selection?From the question, we have
Total number of programmers, n = 10
Numbers to programmers to select, r = 3
The number of ways of selection could be drawn is calculated using the following combination formula
Total = ⁿCᵣ
Where
n = 10 and r = 3
Substitute the known values in the above equation
Total = ¹⁰C₃
Apply the combination formula
ⁿCᵣ = n!/(n - r)!r!
So, we have
Total = 10!/(7! * 3!)
Evaluate
Total = 120
Hence, the number of ways is 120

Last week, a dairy farm produced m kg of cheese. The dairy farm also produced 28 kg more yoghurt than cheese and 3 times as much ice cream as cheese. The dairy farm produced more kilograms of ice cream than yoghurt last week. Write and solve an inequality to work out the possible values of m.
Answers
Answer:
Hence the possible values of m are m > 14
So, the dairy farm produced greater than 14 kg of cheese
Step-by-step explanation:
We have m = kg of cheese,
let y = yogurt
and i = ice cream,
The dairy farm also produced 28 kg more yoghurt than cheese
y = m + 28
3 times as much ice cream as cheese
i = 3m
The dairy farm produced more kilograms of ice cream than yoghurt last week
i > y
so we have,
y = m + 28 (i)
i = 3m (ii)
i > y (iii)
Now, using (i) and (ii) in (iii),
i > y
3m > m + 28 (i = 3m, y = m + 28)
subtracting m from both sides,
3m - m > m - m + 28
2m > 28
dividing by 2 on both sides,
m > 28/2
m > 14

In the circle below, segment AB is a diameter. if the length of are ACB is 6, what is the length of the radius of the circle?
Answers
If AB is the diameter, it means the arc ACB is a semicircle (arc of 180°).
So, to calculate the radius of the circle, we can use the following rule of three:
\(\begin{gathered} \text{arc}\to\text{length} \\ 360\degree\to2\pi r \\ 180\degree\to x \\ \frac{360}{180}=\frac{2\pi r}{x} \\ 2=\frac{2\pi r}{x} \\ 2x=2\pi r \\ x=\pi r \end{gathered}\)The length of a semicircle is given by πr. If this arc measures 6π, we have:
\(\begin{gathered} \pi r=6\pi \\ \frac{\pi r}{\pi}=\frac{6\pi}{\pi} \\ r=6 \end{gathered}\)So the radius of this circle is equal 6 units.

What the meaning of statement this?
Answers
This statement essentially establishes a relationship between the sets X, Y, and z, stating that there exists a subset Y for each element x in X such that the elements in Y are present in some subset z of X.
The given statement is a symbolic representation of a logical proposition involving quantifiers and logical connectives. Let's break down its meaning:
∀ X ∃ Y ∀u(u ∈ Y ↔ ∃z(z ∈ X ∧ u ∈ z))
The symbol ∀ (universal quantifier) indicates that the statement applies to all elements in the set X.
The symbol ∃ (existential quantifier) indicates that there exists at least one element in the set Y.
The statement can be interpreted as follows:
"For all elements x in the set X, there exists a set Y such that for every element u in Y, u is an element of Y if and only if there exists a set z in X such that u is an element of z."
In simpler terms, the statement asserts that for every element x in the set X, there is a set Y that contains elements u if and only if there exists a set z in X that also contains u.
It is important to note that the precise meaning and implications of this statement may depend on the context and interpretation of the sets X, Y, and their elements.

Answers
Using chain rule, the derivative of f(x) = 4√(8x³ + 2x⁴) is
f'(x) = (2/√(8x³ + 2x⁴)) * (24x² + 8x³)
What is the derivative of the function?To find the derivative of the function f(x) = 4√(8x³ + 2x⁴), we can use the chain rule.
Let's break down the function into its components:
u(x) = 8x³ + 2x⁴ (inside function)
v(u) = 4√u (outer function)
To find the derivative, we apply the chain rule, which states:
(f(g(x)))' = f'(g(x)) * g'(x)
In this case, f(g(x)) = v(u(x)), and g(x) = u(x).
First, let's find the derivative of the inner function u(x):
u'(x) = 24x² + 8x³ (using the power rule for differentiation)
Next, let's find the derivative of the outer function v(u):
v'(u) = 4 * (1/2) * 1/√u = 1/√2u = 2/√u
Now, we can apply the chain rule:
f'(x) = v'(u(x)) * u'(x)
f'(x) = (2/√u) * (24x² + 8x³)
f'(x) = (2/√(8x³ + 2x⁴)) * (24x² + 8x³)
The derivative of the function is (2/√(8x³ + 2x⁴)) * (24x² + 8x³)

(a) twenty-eight ninths, square root of nineteen, cube root of eighty-eight
Step-by-step explanation:
When ordering a list of numbers by hand, it is convenient to convert them to the same form. Decimal equivalents are easily found using a calculator.
OrderThe attachment shows the ordering, least to greatest, to be ...
\(\dfrac{28}{9}.\ \sqrt{19},\ \sqrt[3]{88}\)
__
Additional comment
We know that √19 > √16 = 4, and ∛88 > ∛64 = 4, so the fraction 28/9 will be the smallest. That leaves us to compare √19 and ∛88, both of which are near the same value between 4 and 5.
One way to do the comparison is to convert these to values that need to have the same root:
√19 = 19^(1/2) = 19^(3/6) = sixthroot(19³)
∛88 = 88^(1/3) = 88^(2/6) = sixthroot(88²)
The roots will have the same ordering as 19³ and 88².
Of course, these values can be found easily using a calculator, as can the original roots. By hand, we might compute them as ...
19³ = (20 -1)³ = 20³ -3(20²) +3(20) -1 = 8000 -1200 +60 -1 = 6859
88² = (90 -2)² = 90² -2(2)(90) +2² = 8100 -360 +4 = 7744
Then the ordering is ...
28/9 < 19³ < 88² ⇒ 28/9 < √19 < ∛88
Answer:
the ordering is
28/9 < 19³ < 88² ⇒ 28/9 < √19 < ∛88

you roll a standard cube. find p(number greater than 3)
Answers
The probability of rolling a number greater than 3 is 1/2 or 0.5.
When rolling a standard cube, there are six possible outcomes, corresponding to the six faces of the cube. Each face has a number from 1 to 6.
To find the probability of rolling a number greater than 3, we need to determine the number of favorable outcomes (rolling a number greater than 3) and divide it by the total number of possible outcomes (rolling any number from 1 to 6).
The favorable outcomes for rolling a number greater than 3 are: 4, 5, and 6. So, there are three favorable outcomes.
The total number of possible outcomes is six since there are six faces of the cube.
Therefore, the probability of rolling a number greater than 3 is:
Probability = Number of favorable outcomes / Total number of possible outcomes
Probability = 3 / 6
Probability = 1/2
Hence, the probability of rolling a number greater than 3 is 1/2 or 0.5.

For each function, find f(−x) and −f(x) and then determine whether it is even, odd, or neither. Justify your answer. f(x)=2x^2-7x+10
Answers
The function f(x) = 2x² - 7x + 10 is an odd function.
f(-x) = 2(-x)² - 7(-x) + 10
= 2x² + 7x + 10
-f(x) = -[2x²- 7x + 10]
= -2x² + 7x - 10
To determine whether the function f(x) = 2x² - 7x + 10 is even, odd, or neither, we compare f(-x) and -f(x).
1. f(-x) = 2x² + 7x + 10
2. -f(x) = -2x² + 7x - 10
To determine if f(-x) = -f(x) (even function), we substitute -x for x in f(x) and check if the equation holds.
1. f(-x) = 2x² + 7x + 10
= f(x) (not equal to -f(x))
Since f(-x) is not equal to -f(x), the function is not even.
Next, to determine if f(-x) = -f(x) (odd function), we substitute -x for x in f(x) and check if the equation holds.
2. -f(x) = -2x² + 7x - 10
= -(2x² - 7x + 10)
= -(f(x))
Since -f(x) is equal to -(f(x)), the function is odd.

The area of a segment of a circle is (12π-9√3) square inches.
We have to determine the area of a segment of a circle.
The formula for the area of the sector that:
Arc length = πr² (θ/360)
Where r = the radius of the circle,
θ = the angle (in degrees) subtended by an arc at the center of the circle.
As per the shown figure, it is given that:
Central angle θ = 120°
The radius of a circle r = 6 in.
The area of the sector A₁ = π(6)² (120/360)
The area of the sector A₁ = 12π in²
The area of the triangle within the sector:
A₂ = 1/2 × (6√3)(3) = 9√3 in²
Now, the area of the segment is:
A₁ - A₂ = (12π - 9√3) in²

Answers
Answer:
2/3
Step-by-step explanation:
P(b1) = probability of bottle 1 = 1/2
P(b2) = probability of bottle 2 = 1/2
Bottle 1 = 2 green, 1 red ; total = 3
P(red ball1) = 1/3
Bottle 2 : red balls = 2, total balls = 2
P(red ball2) = 2/2 = 1
P(red ball) = [p(b1) * p(redball1)] = 1/2 * 1/3 = 1/6
P(red ball) = [p(b2) * p(redball2)] = 1/2 * 1 = 1/2
1/6 + 1/2 = (1 + 3) / 6 = 4/6 = 2/3
