Jeanine baker makes floral arrangements. she has 18 different cut flowers and plans to use 7 of them. how many different selections of the 7 flowers are possible?
Jeanine can create 43758 different floral arrangements using 7 flowers out of the 18 available. This was calculated using the mathematical concept of combinations.
Explanation:To find the number of different selections of 7 flowers Jeanine can make out of 18, we need to use the mathematical concept of combinations. In this context, the combination formula is used, which is: C(n, k) = n! / [k!(n-k)!]
Where n is the total number, k is the number chosen, and '!' stands for factorial, which is the product of all positive integers less than or equal to the number. Thus, the number of ways Jeanine can choose 7 flowers out of 18 is calculated as follows: C(18, 7) = 18! / [7!(18-7)!] = 43758. Therefore, there are 43758 different ways Jeanine can create floral arrangements using 7 flowers out of the 18 available.
It should be noted that the color of the flowers does not influence the number of combinations if she intends to select any 7 flowers irrespective of their color.

Find one pair of real numbers, $(x,y),$ such that $x + y = 6$ and $x^3 + y^3 = 144.$
[tex]\[\{(3 + \sqrt{5}, 3 - \sqrt{5})}\][/tex] is the one pair of real numbers [tex]\((x, y)\)[/tex] that satisfies the given equations.
Given the system of equations:
[tex]\[x + y = 6\][/tex]
[tex]\[x^3 + y^3 = 144\][/tex]
We can use the identity for the sum of cubes:
[tex]\[x^3 + y^3 = (x + y)(x^2 - xy + y^2)\][/tex]
Substitute [tex]\(x + y = 6\):[/tex]
[tex]\[x^3 + y^3 = 6(x^2 - xy + y^2)\][/tex]
Given [tex]\(x^3 + y^3 = 144\)[/tex], we substitute this into the equation:
[tex]\[144 = 6(x^2 - xy + y^2)\][/tex]
Divide both sides by 6:
[tex]\[24 = x^2 - xy + y^2\][/tex]
Next, we use the square of the sum:
[tex]\[(x + y)^2 = x^2 + 2xy + y^2\][/tex]
Substitute [tex]\(x + y = 6\):[/tex]
[tex]\[6^2 = x^2 + 2xy + y^2\][/tex]
[tex]\[36 = x^2 + 2xy + y^2\][/tex]
We already have [tex]\(x^2 - xy + y^2 = 24\)[/tex]. Let’s denote the first and second equations:
1. [tex]\(x^2 - xy + y^2 = 24\)[/tex]
2. [tex]\(x^2 + 2xy + y^2 = 36\)[/tex]
Subtract the first equation from the second equation:
[tex]\[(x^2 + 2xy + y^2) - (x^2 - xy + y^2) = 36 - 24\][/tex]
[tex]\[3xy = 12\][/tex]
[tex]\[xy = 4\][/tex]
Now, we have two equations:
1. [tex]\(x + y = 6\)[/tex]
2. [tex]\(xy = 4\)[/tex]
We solve these equations using the quadratic formula. Consider the quadratic equation:
[tex]\[t^2 - (x+y)t + xy = 0\][/tex]
[tex]\[t^2 - 6t + 4 = 0\][/tex]
Solve for [tex]\(t\)[/tex] using the quadratic formula [tex]\(t = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}\):[/tex]
[tex]\[t = \frac{6 \pm \sqrt{36 - 16}}{2}\][/tex]
[tex]\[t = \frac{6 \pm \sqrt{20}}{2}\][/tex]
[tex]\[t = \frac{6 \pm 2\sqrt{5}}{2}\][/tex]
[tex]\[t = 3 \pm \sqrt{5}\][/tex]
Thus, the solutions for [tex]\(x\)[/tex] and [tex]\(y\)[/tex] are:
[tex]\[x = 3 + \sqrt{5}, \quad y = 3 - \sqrt{5}\][/tex]
or
[tex]\[x = 3 - \sqrt{5}, \quad y = 3 + \sqrt{5}\][/tex]

How do science and math relate to each other?
Final answer:
Mathematics and science are foundational to engineering, providing the tools and understanding necessary for the engineering design process. They enable engineers to create models, solve design problems, and innovate, thus influencing education and daily life through engineered products.
Explanation:
Science and mathematics are intimately related, especially in fields such as engineering. Mathematics provides the language and tools for abstract reasoning and quantitative analysis, which are fundamental in engineering. Math is used to create mathematical models that describe physical phenomena and to evaluate the merit of different possible solutions. Science, on the other hand, offers understanding of natural phenomena and constraints that inform engineering solutions. Together, math and science are essential throughout the engineering design process, from conceptualization to detailed design implementation, and in team decision-making.
In high school and college, a strong foundation in math and science courses is crucial for success in engineering education. For instance, courses like thermodynamics, circuits, and fluids—commonly referred to as engineering science courses—are grounded in these basic disciplines. The role of science and mathematics in engineering extends beyond educational prerequisites; they are operational tools that engineers use in their work every day to innovate and create products that improve our lives, such as the pocket radio, cell phones, and computers.
The connections between math, science, and engineering are dynamic and multidimensional. They enable engineers to navigate through the iterative steps of the engineering design process, which include analyzing problems, developing solutions, and optimizing products, often moving nonlinearly as real-world complexities dictate adjustments and refinements.
When Mr. Peters drives from Boston to Worcester it takes him 30 minutes travelling at a speed of 60 miles per hour. Mrs. Peters drives from Boston to Worcester and leaves 5 minutes after Mr. Peters but travels at a speed of 90 miles per hour. Who will arrive first? By how many minutes?
Mrs. Peter arrives 5 minutes before Mr. Peter
To find who arrives first we first need to find the speed and time they require to arrive.
Given : From Boston to Worcester
Mr. Peter takes [tex]\rm time=30 \; minutes \; and \;speed= 60 miles /hr[/tex]
Mrs. Peter takes [tex]\rm speed=90 miles/hr[/tex]
We will now calculate Mr. Peters speed,
[tex]\rm 60 \dfrac{miles}{h} \times \dfrac{h}{60minutes}=\dfrac{mile}{min}[/tex]
How to find distance from Boston to Worecester?To find the distance, we will use distance formula
[tex]\rm Distance=speed\times time[/tex]
Here,given that the Mr Peters speed is [tex]\rm 60 miles /hr[/tex] and time is [tex]\rm 30 minutes[/tex]so by distance formula we will find distance of Mr. Peter
[tex]\rm Distance=\dfrac{mile}{min} \times 30 minutes[/tex]
[tex]\rm Distance= 30 miles[/tex]
Similarly, we will now calculate Mrs. Peters speed,
[tex]\rm \dfrac{90miles}{h} \times \dfrac{h}{60minutes}=1.5\times \dfrac{miles}{min}[/tex]
by the given informations we know both covers the same distance
[tex]\rm ie. \;30 miles[/tex]
we will now find distance of Mrs. Peter
[tex]\rm Distance=speed\times time\\ 30miles=1.5\dfrac{miles}{min} \times time\\ time=\dfrac{30miles}{1.5\dfrac{miles}{min}}\\\\ time=20 minutes[/tex]
Here, we know that Mrs.Peter leaves from Boston to Worcester 5 minutes after Mr.Peter so we will add 5 minutes to Mrs. Peters time.
[tex]\rm time=20 minutes+ 5 minutes\\ time=25 minutes[/tex]
Therefore, it is clear that Mrs.Peter arrive before Mr Peter by 5minutes.

Answer:
Ruth was out of Portland at 35mph at 7:00 am
so at 9 am, she was 70 miles ahead of Michael
but Michael was 20 miles ahead by 3 pm.
so in 6 hours, he went past Ruth by 90 miles which is 90/6 = 15mph
Michael speed = ruth speed + 15. = 35 + 15 = 50mph

1.) 4/5
2.) 4/25
3.) 3/100
The answer is actually the second choice 4/25 hope this helps...
Answer: The correct option is (2) [tex]\dfrac{4}{25}.[/tex]
Step-by-step explanation: Given that there are 3 green, 4 yellow, 5 blue and 8 pink marbles in a bag. Fernando is going to draw a marble from the bag, replace it, and then draw another marble.
We are to find the probability that Fernando will get a green or blue marble on the first draw and a pink on the second draw.
Let, S be the sample space for the experiment of drawing a marble from the bag.
Then, n(S) = 3 + 4 + 5 + 8 = 20.
Let E denotes the event of drawing a green or blue marble and F denote the event of drawing a pink marble.
Then, we have
n(E) = 3 + 5 = 8 and n(F) = 8.
Since the second marble is drawn after replacing the first marble,
so the required probability of Drawing a green or blue marble on the first draw and a pink marble on the second draw is
[tex]P\\\\=P(E)\times P(F)\\\\\\=\dfrac{n(E)}{n(S)}\times \dfrac{n(F)}{n(S)}\\\\\\=\dfrac{8}{20}\times\dfrac{8}{20}\\\\\\=\dfrac{4}{25}.[/tex]
Thus, the required probability is [tex]\dfrac{4}{25}.[/tex]

QS is the perpendicular bisector of PR solve for x
The term 'perpendicular bisector' means QS cuts PR into two equal parts at a 90-degree angle. If PR is '2x', then each half is 'x'. To solve for x, we would need data about the lengths of the line segments.
Explanation:Given that QS is the perpendicular bisector of PR, it implies two things. Firstly, QS intersects PR at a 90-degree angle. Secondly, QS splits PR into two equal segments. So, if PR is represented as '2x', then PQ and QR are both 'x'.
Unfortunately, missing information prevents a specific solution for x. We'd need additional data about the lengths of these line segments to solve the equation for x. For instance, if PR = 10, then '2x = 10' which gives us 'x = 5'.

Step-by-step explanation:
Write an equation of te circle with the center (0,0) and radius square root of 15
Answer:
x² + y² = 15
Explanation:
The formula for the equation of a circle is (x - h)² + (y - k)² = r², where the center of the circle is ordered pair (h, k) and r represents the radius (in units).
Now, we plug the given information into the circle equation and simplify.
radius = √15
center (0, 0), h = 0, k = 0
(x - 0)² + (y - 0)² = (√15)²
(x)² + (y)² = (√15)²
x² + y² = 15
The equation of the circle is x² + y² = 15
The equation of the circle with a center at (0,0) and a radius of the square root of 15 is x² + y² = 15. The standard form of the circle equation, (x - h)² + (y - k)² = r², is used with h and k set to 0 to represent the origin.
To write an equation of a circle with the center at the origin (0,0) and a radius of the square root of 15, we use the standard form of the circle equation:
(x - h)² + (y - k)² = r²
Here, (h, k) represents the center of the circle and r is the radius. Since the center of the circle in question is at the origin, h = 0 and k = 0. The given radius is the square root of 15, so we have r = √15. Substituting these values into the standard form gives us the equation:
x² + y² = ( √15 )²
Which simplifies to:
x² + y² = 15
This is the equation for the desired circle centered at the origin with radius √15.
