The probability of rolling an even number with a six-sided, equally weighted die is:_______
a. 3/6.
b. 1/3.
c. 1/2.
d. 1/6.
Answer:
The option that are correct is option a and option c
Step-by-step explanation:
From the question we are told that
The sample space is n = 6 (i.e six sides)
The number of even numbers in the sample space is k = 3 (i.e 2,4, 6)
Generally the probability of rolling an even number with a six-sided, equally weighted die is mathematically represented as
[tex]P(E) = \frac{3}{6}[/tex]
=> [tex]P(E) = \frac{1}{2}[/tex]

Ethan is planting flowers in flower boxes. Each flower box can hold 4 flowers. Ethan will plant 25 red flowers and 13 white flowers in the flower boxes. Part A Write and solve an equation to find the fewest number of flower boxes Ethan will need to plant all the flowers. Show your work.
Answer:
The fewest amount of boxes would be 10
Step-by-step explanation:
I added the 25 red flowers to the 13 flowers and got 38. I then divided 38 by 4 getting 9.5. 9.5 isn't a full box so I rounded to the decimal and got 10.
I hope this what you were looking for.
Using a arithmetic operations , the fewest number of boxes Ethan will need to plant all the flowers ls 10
Creating a
Number of flowers per box = 4 flowersTotal number of flowers to be planted :
Number of red + Number of white flowersTotal number of flowers = 25 + 13 = 38 flowers
Number of flower boxes = (total number of Flowers ÷ number of flowers per box)
Number of flower boxes = (38 ÷ 4) = 9.5 flower boxes
Therefore, the fewest number of boxes that will be needed is 10.

The function f given by f(x)=3x5−4x3−3x has a relative maximum at x?
Answer:
We have the function:
f(x) = 3*x^5 - 4*x^3 - 3*x
To find the maximum/minimums, we first need to look at the roots of the first derivative of f(x), this is:
f´(x) = 5*3*x^4 - 3*4*x^2 - 3
f´(x) = 15*x^4 - 12*x^2 - 3
We can do the change of variable:
u = x^2
Then we can rewrite:
f'(u) = 15*u^2 - 12*u - 3
This is a quadratic equation, the solutions will be obtained by the Bhaskara´s equation:
So the solutions are:
[tex]u = \frac{+12 +- \sqrt{(-12)^2 - 4*(-3)*15} }{2*15} = \frac{12 +- 18}{30}[/tex]
Then the two solutions are:
u = (12 + 18)/30 = 1
this leads to:
x^2 = 1, then we can have x = ± 1
the other solution is:
u = (12 - 18)/30 = -6/30 = -(1/5)
and x^2 = -(1/5), then:
x = ±√(1/5)*i
So those are the possible values for the minimum/maximums.
Now to see it, we need to look at the second derivative ad see iff:
f´´(x) > 0 then x is a minimum
f''(x) < 0, then x is a maximum.
We have that:
f´´(x) = 4*15*x^3 - 2*12*x
f´´(x) = 60*x^3 - 24*x
Notice that the two complex roots will lead to complex values of f(x), so these can be ignored here, then we have to try only with x = ± 1.
f´´(1) = 60*1^3 - 24*1 = 36
then x = 1 is a minimum.
f´´(-1) = 60*(-1)^3 -24*-1 = -36
then x = -1 is a maximum.
Then we can conclude that the relative maximum is at x = -1
The function f given by [tex]f(x) = 3x^5-4x^3-3x[/tex] has a relative maximum at
x = -1
The given function is:
[tex]f(x) = 3x^5-4x^3-3x[/tex]
Find the derivative of the function:
[tex]f'(x)=15x^4-12x^2-3[/tex]
Find the critical points by equation f'(x) to zero
[tex]15x^4-12x^2-3=0\\\\5x^4-4x^2-1=0[/tex]
By solving the equation above, the critical points are:
x = -1, x = 1
Find the second derivative of f(x)
[tex]f''(x)=60x^3-24x[/tex]
[tex]f''(-1)=60(-1)^3-24(-1)\\\\f''(-1)=-36[/tex]
Since f''(-1) < 0, x = -1 is a maximum point
[tex]f''(1)=60(1)^3-24(1)\\\\f''(1)=36[/tex]
Since f''(1) > 0, x = 1 is a minimum point
Therefore, the function [tex]f(x) = 3x^5-4x^3-3x[/tex] has a relative maximum at x = -1

Two triangles A B C and D F G. A B is 5 inches. B C is 6 inches. A C is 7 inches. D F is 15 inches. F G is 18 inches. Angle B is congruent to angle F.
I believe the answer is 5/7=15/DG.
Please, do correct me if the answer seems wrong, thank you.
The proportion which can be used to describe the value of DG is
15 x 7 = 5 x DG
What are similar triangles?
Two triangles are said to be similar if their sides are proportional and their angles are equal.
Given data ,
The two triangles are ΔABC and ΔDFG are similar
Length of AB = 5 inches
Length of BC = 6 inches
Length of AC = 7 inches
Length of DF = 15 inches
Length of FG = 18 inches
And , ∠B is congruent to ∠F
The two triangles are similar , so the ratio of
AB / DF = BC / FG = AC / DG
Therefore , 5 / 15 = 7 / DG
DG = 21 inches
Hence , the proportion used to find the value of DG is 15 x 7 = 5 x DG

If I had 4 eggs
A thief gives me 3 eggs
My farm rooster lays 5 eggs
How many eggs do I have?
Answer:
You have 3 eggs.
Step-by-step explanation:
You "had" 4 eggs, those do not count. A thief then gave you 3 eggs. And lastly, a rooster does not lay eggs. In conclusion, you have 3 eggs.
The total number of eggs he finally has as inferred from the riddle is 3 eggs.
Evaluating each sentence :
If I had 4 eggs ; This is an imagination, hence, the speaker was only imagining if he had. Hence, total here is 0
A thief gave out 3 eggs ; Hence, the total number of eggs = (0 + 3) = 3 eggs
Farm Rooster laying 5 eggs is impossible S Farm roosters do not lay eggs. Number of eggs here is 0.
Hence, the total number of eggs = (0 + 3 + 0) = 3 eggs.
