Answer:
336
Step-by-step explanation:
The total number of ways to order your favorite 3 desserts from a menu of 8 is 336, the correct option is D.
How many ways k things out of m different things (m ≥ k) can be chosen if order of the chosen things doesn't matter?We can use combinations for this case,
Total number of distinguishable things is m.
Out of those m things, k things are to be chosen such that their order doesn't matter.
This can be done in total of
[tex]D ^mC_k = \dfrac{m!}{k! \times (m-k)!} ways.[/tex]
If the order matters, then each of those choice of k distinct items would be permuted k! times.
So, total number of choices in that case would be:
[tex]^mP_k = k! \times ^mC_k = k! \times \dfrac{m!}{k! \times (m-k)!} = \dfrac{m!}{ (m-k)!}\\\\^mP_k = \dfrac{m!}{ (m-k)!}[/tex]
This is called permutation of k items chosen out of m items (all distinct).
We are given that;
The number of ways to order 3 desserts from a menu of 8 is given by the combination formula:
C(8,3) = 8! / (3! * (8-3)!) = 56
This means there are 56 different ways to choose 3 desserts from the menu of 8. Once the desserts are chosen, there are 3! = 6 ways to order them.
For 3 desserts from a menu of 8
56 * 6 = 336
Therefore, by combinations and permutations answer will be 336.

The radius of a circle is 5 cm. Find its area to the nearest tenth.
Answer:
A = 78.5 cm²
Step-by-step explanation:
Area of Circle = πr²
A = (3.14)(5)²
A = (3.14)(25)
A = 78.5 cm²
The area formula of a circle is r² x π.
With that being said, we can now substitute in our radius value.
(5)² x π
From there, we can find the square root of the radius.
(25) x π
And then we can multiply by pi to solve.
78.539816..
Finally, we'll round to the nearest tenth to get our answer.
78.5
Therefore, the area of the circle is 78.5 cm.

Find the upper bound for the following lengths:
a) 60 cm measured to the nearest cm.
b) 96.3 cm measured to the nearest tenth of a cm.
Answer:
60cm=60.5cm
96.3cm=96.35cm
The upper bound lengths are 60.4 cm and 96.34 cm for the given lengths of 60 cm and 96.3 cm.
What are the upper and lower bounds of an approximation?The upper bound for the given value is the numerical value that is rounded for the next value of the given value.
the Lower bound for the given value is the numerical value that is rounded for the previous value or the estimated value of the given value.
Approximation of the given lengths:a) 60 cm - this is rounded off for the values,
Lower bound - 59.5 cm and Upper bound - 60.4 cm
b) 96.3 cm - this is rounded off for the values,
Lower bound - 96.25 cm and Upper bound - 96.34 cm (rounded to the nearest tenth)

What is the rectangular equivalence to the parametric equations?
x(θ)=3cosθ+2
y(θ)=2sinθ−1 ,
where 0≤θ<2π .
Answer:
For x(θ) = 3cosθ + 2
y² = [9x²/(x - 2)²] - x²
For x(θ) = 3cosθ + 2
x² = [4y²/(y - 1)²] - y²
Step-by-step explanation:
Given the following equivalence:
x² + y² = r²
r = √(x² + y²)
x = rcosθ
cosθ = x/r
y = rsinθ
sinθ = y/r
Applying these to the given equations,
x(θ) = 3cosθ + 2
x = 3(x/r) + 2
xr = 3x + 2r
(x - 2)r = 3x
r = 3x/(x - 2)
Square both sides
r² = 9x²/(x - 2)²
(x - 2)²r² = 9x²
(x - 2)²(x² + y²) = 9x²
(x² + y²) = 9x²/(x - 2)²
y² = [9x²/(x - 2)²] - x²
y(θ) = 2sinθ - 1
y = 2y/r - 1
yr = 2y - r
(y - 1)r = 2y
r = 2y/(y - 1)
Square both sides
r² = 4y²/(y - 1)²
x² + y² = 4y²/(y - 1)²
x² = [4y²/(y - 1)²] - y²

The box plot compares the number of events that Mrs. Cai’s and Mr. Roland’s classes won over the last 10 years on the school’s field day.
A number line goes from 0 to 10. Mrs. Cai's class's whiskers range from 0 to 8, and the box ranges from 2 to 4. A line divides the box at 3. Mr. Roland's class's whiskers range from 1 to 8, and the box ranges from 4 to 7. A line divides the box at 5.
Based on the data in the box plots, what is the best evidence to show which class has had greater success on field day over the last 10 years?
Mrs. Cai’s class was more successful because her interquartile range was less spread out.
Mrs. Cai’s class was more successful because she had the greater total spread.

4

4/3
-4/3

Answer:
Hi Gracie pretty sure the answer is 4/3, -2
Step-by-step explanation:
The zeroes of the function f(x) = (3x − 4)(x + 2) is 4/3, -2 option (3) and option (5) are correct.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a function:
f(x) = (3x - 4)(x +2)
To find the zeroes of the function:
Applying zero product property:
(3x - 4)(x +2) = 0
The above equation represents a quadratic equation,
As we know, Any equation of the form[tex]\rm ax^2+bx+c=0[/tex] where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.
3x - 4 = 0
3x = 4
x = 4/3
or
x + 2 = 0
x = -2
Thus, the zeroes of the function f(x) = (3x − 4)(x + 2) is 4/3, -2 option (3) and option (5) are correct.

The quotient of two numbers is 4, and the difference is 3. What are the two numbers
Answer:
The numbers are 4 and 1
Step-by-step explanation:
Let x and y be the numbers
Quotient is division
x/y = 4
x-y =3
Taking the first equation and multiplying each side by y
x = 4y
Replacing into the second equation
4y -y = 3
3y = 3
Divide by 3
3y/3 = 3/3
y=1
Now we can find x
x -y =3
x-1 =3
Add 1 to each side
x= 4

Which expression represents the distance between point (0, a) and point (a, 0) on a coordinate grid?
2a1
Answer:
[tex]\sqrt{2} a[/tex]
Step-by-step explanation:
The distance between point (x1,y1) and (x2,y2) on a coordinate plane is given by expression [tex]\sqrt{(x1-x2)^2+(y1-y2)^2}[/tex]
In the problem given coordinate points are
(0, a) and (a, 0).
Thus, distance between these points are given by
[tex]distance = \sqrt{(x1-x2)^2+(y1-y2)^2}\\=>distance = \sqrt{(0-a)^2+(a-0)^2}\\=>distance = \sqrt{(a)^2+(a)^2}\\\\=>distance = \sqrt{2a^2}\\=>distance = \sqrt{2} a[/tex]
Thus , expression [tex]\sqrt{2} a[/tex] gives the distance between point (0, a) and point (a, 0) on a coordinate grid.
