A spinner and 4 cards are shown below: A spinner with 5 equal sectors is shown in the figure. The colors Green, Blue, Purple, Yellow, and Red are marked on it. The arrow points at the purple color. Four cards are shown on the right side. The colors Red, Yellow, Blue, and Pink are marked on them. Jane spins the spinner and selects a card without looking. What is the probability that the spinner stops at purple and a pink card is selected?
Answers
The probability of the spinner landing on purple and a pink card being selected is 1/20 or 5%.
Explanation:The subject of this question is probability, a branch of Mathematics. Let's determine the probability of the spinner landing on purple and choosing the pink card. There are 5 equal sectors in the spinner, which means every color has a 1/5 chance to be chosen on any spin. Therefore, the probability of it landing on purple is 1/5.
As for the cards, there are four of them, meaning each card also has a 1/4 chance of being selected. Therefore, the probability of selecting a pink card is 1/4.
Because these are independent events (one does not affect the outcome of the other) we can calculate the simultaneous probability by multiplying the individual probabilities. Thus, the total probability of the spinner landing on purple and a pink card being selected is (1/5) * (1/4), which equals 1/20 or 5%.

How many different arrangements of the letters in the word SCHOOL are there?
A) 1440
B) 720
C) 360
D) 120
Answers
If you don't consider the duplication of 2 O's, then the total cases are:
6! = 720
However, we should eliminate the duplication cases of 2 O's:
Since for each arrangement, you can always switch 2 O's to create a duplicated case, for example, SCHOOL, you can switch the 2 O's but they are duplicated
So the final answer will be 720 / 2 = 360

Answers
20x⁶/15y⁵ × 5y²/6x⁴
The first thing to do is to simplify the easiest terms: the constants. Just multiply all the constants on the numerator and all the constants on the denominator independently. The simplified constant becomes
(20*5)/(15*6) = 10/9
So, the equation to be solved now is
10x⁶y²/9y⁵ x⁴
So, I also multiplied all the variables in the numerator and denominator independently, just like the constants. Then, you apply the laws of exponents. When you divide terms with exponents of the same value of the base, you subtract the exponent on the numerator minus the denominator. It goes like this:
10/9 * x⁶⁻⁴*y²⁻⁵ = 10/9*x²y⁻³
Now, when the exponent as written to the power of a negative exponent, just simply take its reciprocal to make it positive. So, the final answer is
10x²/9y³ or that is letter D.

A hyperbola with center at (0, 0), with x-intercepts at (4, 0) and (-4, 0), with b = 1, and opening horizontally has the equation
Answers
Answer:
It´s x2/16-y2/1=1
Step-by-step explanation:
The equation of the hyperbola is x²/16 - y²/1 =1
What is a hyperbola?A symmetrical open curve formed by the intersection of a circular cone with a plane at a smaller angle with its axis than the side of the cone. A plane curve generated by a point so moving that the difference of the distances from two fixed points is a constant : a curve formed by the intersection of a double right circular cone with a plane that cuts both halves of the cone.
Given here: hyperbola with center at (0, 0), with x-intercepts at (4, 0) and (-4, 0), with b = 1 . Now we know The standard equation of the hyperbola is [(x²/a²) – (y²/b²)] = 1, where the X-axis is the transverse axis and the Y-axis is the conjugate axis.
Therefore the hyperbola opening horizontally has the equation with x-intercepts at (4, 0) and (-4, 0), with b = 1 is x²/16 - y²/1 =1
Hence, The equation of the hyperbola is x²/16 - y²/1 =1

Answers
To represent the elevations at which Aimee should fly her plane, the inequality h ≥ 500 is used, where h represents Aimee's elevation in meters. This indicates that Aimee must fly at an elevation of 500 meters or higher, as per the air traffic controller's instructions.
Explanation:The question asks for an inequality that represents elevations at which Aimee should fly her plane, according to the instructions given by the air traffic controller. Aimee is told to fly at 500 meters above the ground or higher. To write this inequality, we let h represent the elevation (in meters) at which Aimee should fly. Therefore, the inequality that only allows for elevations 500 meters or higher is: h ≥ 500.
This inequality means that Aimee's elevation, h, should be greater than or equal to 500 meters. This is a simple linear inequality in one variable, which is a fundamental concept in algebra. Understanding how to represent real-world scenarios with inequalities is crucial in solving problems related to constraints and conditions that have a range of possible values.

in 2006, the population of a certain country per square mile of land was 81. In 2014, the persons per square mile was 85.24. assume the relationship between years, x, and persons per square mile,y, is a linear relationship
Answers
The population density in the country increased at a rate of about 0.53 persons per square mile each year between 2006 and 2014, demonstrating a linear relationship.
Explanation:You are looking at a linear relationship between years and population density in a particular country. Years are represented by 'x' and persons per square mile are represented by 'y'. To find the relationship, we need to identify the slope of the line, which represents the rate of change in population density per year.
To find the slope, we subtract the y-values and divide by the change in x-values: (85.24 - 81) / (2014 - 2006) = 0.53 persons per square mile per year.
This tells us that, on average, the population density in this country increased by about 0.53 persons per square mile each year between 2006 and 2014.

The population density of the country increased at a linear rate of around 0.53 persons per square mile each year between 2006 and 2014.
Explanation:In this problem, we are dealing with a linear relationship between years(x) and persons per square mile(y). Here, we need to find the slope of the line to understand the rate at which the population density is increasing per year. The slope of a line in a linear relationship is given by the formula slope = (y2 - y1) / (x2 - x1). Here, (x1, y1) refers to the year and population density in 2006 which are (2006, 81) respectively, and (x2, y2) refer to the year and population density in 2014 which are (2014, 85.24) respectively.
Substitute these values into the formula:
Slope = (85.24 - 81) / (2014 - 2006)= 0.53 (approx).
So, the population density increase was about 0.53 persons per square mile per year between 2006 and 2014.

For the following true conditional statement, write the converse. If the converse is also true, combine the statements as a biconditional. If x = 3, then x2 = 9.
Answers
Answer: The converse of the given statement is if [tex]x^2=9[/tex] ,then x=3.→ which is not true.
We cannot form a biconditional statement for the given statement because the converse is not true.
Step-by-step explanation:
Given statement: If x = 3, then [tex]x^2=9[/tex]
The converse statement of conditional statement that "if p then q" is "if q then p".
therefore, the converse of the given statement is if [tex]x^2=9[/tex] ,then x=3.
But the converse is not true since if [tex]x^2=9[/tex] then x can be 3 or -3 .
∵ [tex]3^2=9[/tex] and [tex](-3)^2=9[/tex]
A biconditional statement is true if and only if both the conditional statement and its converse are true.
Therefore, we cannot form a biconditional statement for the given statement because the converse is not true.
The converse of the conditional statement 'If x=3, then x²=9' is 'If x²=9, then x=3'. As both these statements are true, they can be combined into a biconditional statement 'x=3 if and only if x²=9'.
Explanation:
In your question, you asked how to write the converse of a given conditional statement and then combine them if the converse is also true. The original conditional statement is 'If x = 3, then x² = 9.' The converse of this statement would be 'If x² = 9, then x=3.' In this case, the converse is also true because if x² equals 9 then x does indeed equal 3. Therefore, we can combine the conditional statement and its converse into a biconditional statement: 'x = 3 if and only if x² = 9.'

Andre owned a 1/4 acre lot. he wanted to construct a 120’ x 80’ tennis court on the lot. what approximate percentage of the lot will be left over, if any, when he has completed the construction?
Answers
A = 120' x 80'
A = 9600 ift
Then, we convert the area in ft² to acres,
A = (9600 in²)(2.3 x 10^-5/ 1 in²)
A = 0.24 acre
The portion of land remaining is,
A of remaining = 0.25 acre - 0.24 acre
= 0.1 acre
The remaining portion is for Andre's studies.
This, 0.1 ft² is equal to the 4% of the given area of the court.
Answer:
Answer is approx 12%
Step-by-step explanation:
Total land owned by Andre = [tex]\frac{1}{4}=0.25[/tex] acres
He wants to construct a 120 feet x 80 feet tennis court on the lot.
Means the area of the court will be = [tex]120\times80=9600[/tex] square feet.
9600 square feet = 0.22 acres (divide the area value by 43560 as 1 acre has 43560 sq feet)
Area left in acres = [tex]0.25-0.22=0.03[/tex] Acres
Hence, the approximate percentage left over will be = [tex]\frac{0.03}{0.25}\times100= 12[/tex]%
Δ abc is isosceles. angles b and c are congruent. the m∠a = 40°, m∠b = (3x + 1)°. find x.
a.13
b.23
c.46.3
d.70
Answers
Final answer:
In an isosceles triangle with angles B and C congruent, and with m∠A equal to 40°, the equation to find x is 40° + 2(3x + 1)° = 180°. Solving this equation yields x = 23°, which corresponds to option b.
Explanation:
Since ΔABC is an isosceles triangle and angles B and C are congruent, m∠B = m∠C. Given that m∠A = 40°, we can set up an equation to find x since the sum of all angles in a triangle equals 180°.
Equation: 40° + (3x + 1)° + (3x + 1)° = 180°
Combining like terms:
40° + 2(3x + 1)° = 180°
40° + 6x + 2° = 180°
6x + 42° = 180°
6x = 180° - 42°
6x = 138°
x = 23°
Therefore, the value of x is 23°, which corresponds to option b.
