Answer 2
Answer:

The property that allows the statement 10 = y to be written y = 10 is:

                       Symmetric

Step-by-step explanation:

We know that for any set A. if a and b are two elements of the set A.

Then if a is related to b by some relation then by the symmetric property b must be related to a by the same property.

Here 10 is related to y by the equality relation.

i.e. 10=y

Hence, by the symmetric property we have that y must be related to 10 by the same equality relation.

i.e.   y=10

The local weather report states that the probability that it will snow today is 20% and the probability that it will snow tomorrow is 40%. Which of the following is a true statement?
A.
It is not very likely that it will snow both today and tomorrow.

B.
It is very likely that it will snow both today and tomorrow.

C.
It is impossible that it will snow both today and tomorrow.

D.
It is certain that it will snow both today and tomorrow.

Answers

Final answer:

The probability of it snowing both today and tomorrow is 8%, based on the given probabilities for individual days. Therefore, the most accurate statement is that it's not very likely for it to snow on both days.

Explanation:

The question revolves around understanding the concept of probability. In the context of probability, you multiply the probabilities of two independent events (like it snowing on two different days) to get the probability of both occurring.

To find out if it will snow both today and tomorrow, we multiply the probability it will snow today (20% or 0.2) by the probability it will snow tomorrow (40% or 0.4). This gives us a probability of 0.08 or 8%, which means that it's not very likely that it will snow both today and tomorrow.

So, the correct answer would be Option A: It is not very likely that it will snow both today and tomorrow.

What is the area of this polygon?
units²

5-sided polygon on a coordinate plane with vertices F, N, S, C, W. Point f is at (negative 4, negative 2), point N is at (2, 4), point s is at (5, negative 2), point c is at (5, negative 4), and point w is at (negative 4, negative 4)

Answers

Step 1) Draw a line from point F to point S. A rectangle forms (rectangle FSCW)

Step 2) Find the area of this rectangle. The area is 18 square units because it is 2 units high and 9 units across (9*2 = 18). You can count out the spaces or you can note how we go from x = -4 to x = 5 so subtracting the values gives -4-5 = -9 which has an absolute value of 9. 

Step 3) Find the area of triangle FSN. The base is 9 units and the height is 6 units (count out the spaces or subtract y values). So the area is A = b*h/2 = 9*6/2 = 54/2 = 27

Step 4) Add up the area of the rectangle to the area of the triangle: 18+27 = 45

Final Answer: 45 square units

note: another way to find the answer is to find the area of rectangle WABC where point A is at (-4,4) and point B is at (5,4). Then subtract off the triangular areas of AFN and BNS

In this exercise we have to use the knowledge of polygon area to calculate the area of ​​a trapezoid, in this way we find that:

[tex]45 units[/tex]

So find the area of this rectangle,  this area will be:

[tex]9*2 = 18[/tex]

Find the area of triangle FSN, this area will be:

[tex]A = b*h/2 = 9*6/2 = 54/2 = 27[/tex]

Sum all the areas will be:

1.) 4/5
2.) 4/25
3.) 3/100

Answers

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]

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?

Answers

Final answer:

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.

QS is the perpendicular bisector of PR solve for x

Answers

2x - 20 = 70 - x

3x - 20 = 70

3x = 90

x = 30
Final answer:

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'.

Write an equation of te circle with the center (0,0) and radius square root of 15

Answers

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.

A certain number of bacteria are in a petri dish. If the growth rate is 2.7 percent per hour, how many hours will it take the bacteria to double in number?

Answers

Final answer:

Using the rule of 70, which states that the doubling time in hours is equal to 70 divided by the growth rate percentage, it will take approximately 25.93 hours for the bacteria to double in number at a growth rate of 2.7 percent per hour.

Explanation:

To calculate the time it will take for the bacteria to double in number with a growth rate of 2.7 percent per hour, we can use the rule of 70. The rule of 70 states that we can find the doubling time by dividing 70 by the percentage growth rate.

Doubling time = 70 ÷ growth rate percentage = 70 ÷ 2.7 ≈ 25.93

Therefore, it will take approximately 25.93 hours for the bacteria to double in number.

Answer:

10 mile per hour = 16.1 kilometers per h our

Step-by-step explanation:

We know that  

1 mile = 1.61 kilometers

We are supposed to convert speed given in miles per hour (mph) to kilometers per hours (kmph)

In order to do so ,  

1 mile = 1.61 kilometers

1 mile per hour = 1.61 kilometers per hour

Multiplying both sides by 10 we get

10 miles per hour = 1.61 *10 kilometers per hour  

10 miles per hour = 16.1 kilometers per hour

Hence our speed in kilometers per hour is 16.10 kmph

Answers

For this case we have the following equation:
 h = -16t ^ 2 + 184t + 20
 Deriving we have:
 h '= -32t + 184
 We equal zero and clear t:
 -32t + 184 = 0
 32t = 184
 t = 184/32
 t = 5.75 s
 Then, the maximum height is given by:
 h (5.75) = -16 * (5.75) ^ 2 + 184 * (5.75) + 20
 h (5.75) = 549 feet
