enter the letters of the points that satisfy the inequalities \[y > -\frac{1}{2} x 2 \quad \text{and} \quad 2x y \le 8.\]
An inequality is a mathematical statement that compares two expressions using an inequality symbol. In this case, we have two inequalities that involve the variables \(x\) and \(y\): \(y > -\frac{1}{2} x 2\) and \(2x y \le 8\).
To find the points that satisfy these two inequalities, we must first solve for both \(x\) and \(y\).
To find the points that satisfy the first inequality, we can solve for \(y\) and substitute it into the second inequality:
\[y > -\frac{1}{2} x 2 \implies y = -\frac{1}{2} x 2 + k \quad \text{where} \quad k > 0\]
\[2x (-\frac{1}{2} x 2 + k) \le 8 \implies x^2 - 4x + 8 \le 0\]
Solving for \(x\) yields two solutions: \(x = 2 \pm \sqrt{2}\). To find the points that satisfy both inequalities, we must test both of these solutions in the original inequalities. For \(x = 2 + \sqrt{2}\), we have:
\[y > -\frac{1}{2} \cdot (2 + \sqrt{2}) \cdot 2 \implies y > 4 - 4\sqrt{2}\]
\[2 \cdot (2 + \sqrt{2}) \cdot y \le 8 \implies 8 + 8\sqrt{2} \le 8 \quad \text{which is true}\]
Therefore, the point \((2 + \sqrt{2}, 4 - 4\sqrt{2})\) satisfies both inequalities. For \(x = 2 - \sqrt{2}\), we have:
\[y > -\frac{1}{2} \cdot (2 - \sqrt{2}) \cdot 2 \implies y > 4 + 4\sqrt{2}\]
\[2 \cdot (2 - \sqrt{2}) \cdot y \le 8 \implies 8 - 8\sqrt{2} \le 8 \quad \text{which is true}\]
Therefore, the point \((2 - \sqrt{2}, 4 + 4\sqrt{2})\) also satisfies both inequalities.

Answer: (i) 10% (ii) 60% (iii) 40%
Step-by-step explanation:
(i) Newar language = 65%
Gurung language = 45%
Total covers = 110 but to sum it up to base that is 100% then 110-100 is 10.
so, 10% of people speak both the language.

use the given information to complete the proof of the following theorem. the angles opposite the two congruent sides of an isosceles triangle are congruent.
The angle opposite to the two congruent sides of an isosceles triangle are congruent.
To prove that the angles opposite the two congruent sides of an isosceles triangle are congruent, we can use the following steps:
Draw a diagram of an isosceles triangle with two congruent sides and two corresponding angles opposite these sides. Label the vertices A, B, and C, with B being the vertex opposite the base of the triangle.Since the triangle is isosceles, AB = AC.Since the sides AB and AC are congruent, we can apply the SAS Congruence Theorem to triangles ABC and ACB. This states that if two sides of a triangle are congruent and the included angle is congruent, then the triangles are congruent.Therefore, triangles ABC and ACB are congruent.Since triangles ABC and ACB are congruent, the corresponding angles are congruent. In particular, ∠BAC is congruent to ∠CAB.Therefore, the angles opposite the two congruent sides of an isosceles triangle are congruent.This completes the proof of the theorem

Ratio is the relation between two amounts that shows the number of times one value contains within the other.
What is Ratio?
A ratio in mathematics illustrates how many times one number contains another. For example, if a dish of vegetables contains eight tomato and six carrots, the tomato-to-carrot ratio is eight to six (that is, 8:6, which is equivalent to the ratio 4:3). Similarly, the proportion of carrots to tomato is 6:8 (or 3:4), while the proportion of tomato to overall fruit is 8:14. (or 4:7). A ratio's numbers can be any quantity, such as a count of persons or things, or measures of lengths, weights, time, and so forth. In most situations, both numbers must be positive.

consider two medical tests, a and b, for a virus. test a is 90% effective at recognizing the virus when it is present, but has a 5% false positive rate (indicating that the virus is present, when it is not). test b is 95% effective at recognizing the virus, but has a 10% false positive rate. the two tests use independent methods of identifying the virus. the virus is carried by 2% of all people.Say that a person is tested for the virus using only one of the tests, and that test comes back positive for carrying the virus.Which test returning positive is more indicative of someone really carrying the virus? Justify your answer mathematically (i.e. writing down your calculations).
P(V|B)>P(V|A)
P(V|B)>P(V|A), so Bob is more likely to have virus, however is is still very small probability (only 15%), so in order to confirm illness, he should make one more test.
P(A/V) = 0.95
From the text we can also conclude, that
P(A| V) = 0.1
P(B|V) = 0.9
P(B| V) = 0.5
P(V)= 0.1
What we need to calculate and compare is P( V |A) and P(V|B)
P(V∩A) = P(A) . P(V|A) => P(V|A)
P(V∩A) / P(A)
P(V∩A) means, that Joe has a virus and its detected so.,
P(V∩A) = P(A) . P(V|A) = 0.01 × 0.95
= 0.0095
P(A) is sum of two options: "Joe has virus and it is detected" and "Joe has no virus, but it was mistakenly detected", therefore:
P(A) = P(A) . P(V|A) + P(≈V)
P(A|≈V) = 0.01 . 0.95 + 0.99 . 0.1
= 0.1085
Dividing those 2 numbers we obtain
P(V|A) = 0.0095 / 0.1085
= 0.0875576036
Analogically,
P(V|B) = P(V∩B) / P(B)
= 0.01 . 0.9 / 0.01 . 0.9 + 0.99 . 0.1
= 0.1538461we observe that P(V|B) > P(V|A) ,
so Bob is more likely to have virus, however is is still very small probability (only 15%), so in order to confirm illness, he should make one more test.

If another teacher with an age of 45 is added to the data, how would the mean be impacted?
THANKS! ANSWER FAST!
Answer: To find the mean of the number of students who left school early, we must add all of the numbers together and then divide the sum by the number of days.
48 + 62 + 75 + 43 + 32 + 52 + 70 + 63 + 81 + 40 + 38 + 67 = 671
The mean of the number of students who left school early is 56.75 (671 / 12).
This mean represents the average number of students who left school early each day over the 12-day period. It tells us that on average, about 56.75 students left school early each day.
Step-by-step explanation: 2. The mean of the group of teachers' ages is currently (25+32+33+35+41+43+45+48+52+55+60+62)/12=45.5. If another teacher with an age of 45 is added to the data, the mean will be (25+32+33+35+41+43+45+45+48+52+55+60+62)/13=44.5. The mean will be slightly lower, as the additional value of 45 is being added to the sum, but the number of values being averaged is also increasing by 1.

kari is thinking about buying a laptop that cost $750 on sale if the sales tax is 7.5% how much money will she need in total to buy the computer
Answer: 806.25
Step-by-step explanation: First, we need to find how much the sales tax is worth in dollars. Recall the formula:
Worth = Wole number x part percent / 100
Now, plug in the numbers:
Worth = 750 x 7.5 / 100
So, 750 x 7.5 = 5625
So, 5625 / 10 = 56.25
But remember, $56.25 is the amount of the SALES TAX. To find the total, we need to add 56.25 to 750. So,
750 + 56.25 = 806.25
Therefore, $806.25 is the TOTAL AMOUNT she needs to pay.

Spotify charges $0.98 for individual song and $10 for entire album
According to the question,
Spotify charges "x" dollars for individual songs and "y" for entire album
Also, Person A pays $14.9 to download 5 individual songs and 1 album
Which can be written as
=> 5x + y = 14.9 --------------(1)
Person B pays $22.95 to download 3 individual songs and 2 albums
=> 3x + 2y = 22.95 ---------(2)
Solving these two linear equations by elimination method
Multiplying equation (1) by 2
=> 10x + 2y = 29.8
Now, subtracting these equation
10x + 2y - 3x - 2y = 29.8 - 22.95
=> 7x = 6.85
=> x = 0.98
Replacing value of x in equation (1),
=> 5(0.98) + y = 14.9

The minimum value, the first quartile (Q1), the median, the third quartile (Q3), and the maximum value must all be calculated before we can create a box plot for the rating points data.
The median of the lower and upper halves of the data must be determined in order to determine the first and third quartiles, respectively. The numbers from the minimum to the median make up the lower half of the data, while the values from the median to the highest make up the upper half.
We must first organize the numbers in numerical order: 93.5, 96.3, 97.9, 98.9, 99.3, 101.1, 103.9, 104.8, 105.1, 109.5. This will help us determine the median of the lower half of the data. The lower half's mean, which is (99.3 + 101.1) / 2 = 100.2, is then the average of the fifth and sixth values.
Again, the numbers must be arranged in numerical order to determine the median of the upper half of the data: 93.5, 96.3, 97.9, 98.9, 99.3, 101.1, 103.9, 104.8, 105.1, and 109.5. The average of the sixth and seventh numbers, or (101.1 + 103.9) / 2, equals 102.5, which is the median of the top half.

Hi i need help with this question.
The perimeter of the state of Wyoming, given the rectangle ABCD and the vertices, is 1, 282 miles
How to find the perimeter?The perimeter is the distance around the shape so to find the perimeter of the shape, you need to find the distance between the sides of the rectangle and then add them up.
The distance between vertices can be found by the formula :
= ((x2 – x1)² + (y2 – y1)²)
The distance between AB is therefore 3.65 miles.
The distance between BC is 2.76 miles
The distance between CD is 3.65 miles.
The distance between AD is 2.76 miles
The perimeter of Wyoming is therefore :

What is a variable?
Any qualities, quantity, or number that can be gauged or tallied qualifies as a variable. A data item is another name for a variable. Examples of variables include age, sex, company income and expenses, country of birth, capital expenditures, class grades, eye color, and vehicle kind.
Given equation is y = 2x + 24
24 is represents the entry fee in the amusement park.
where y represents the total amount of money, in dollars and cents, and a represents the number of rides Carlos goes on.
Putting x = 0 in the equation to find the total amount of money Carlos will spend if he goes on o rides:
y = (2 × 0) + 24
y = 24
Putting x = 1 in the equation to find the total amount of money Carlos will spend if he goes on 1 rides:
y = (2 × 1) + 24
y = 2 + 24
y = 26
The change in the total amount of money he will spend for every additional ride he goes on is $26 - 24 = $2
Putting x = 100 in the equation to find the total amount of money Carlos will spend if he goes on 100 rides:
y = (2 × 100) + 24
y = 200 + 24
y = 224

Find the inverse of y = 5x² - 6.
Answer:
The correct answer is the 3rd option
Solve the problem by finding x. I don’t know how to? Do you.
The solution of the logarithmic equation:
ln(x - 7) = 3
Is x = 27.09
How to solve the logarithmic function?Here we have the following logarithmic function:
ln(x - 7) = 3
And we want to solve this for x.
Remember that the logarithmic function is the inverse of the exponential function, so now we can use the exponential function in both sides so we get:
exp( ln(x - 7) ) = exp(3)
x - 7 = exp(3)
Now we can add 7 in both sides so we isolate x, we will get:
x = exp(3) + 7
x = 27.09
That is the solution of the logarithmic equation.

cars: an Escort, a Lexus, a Nissan, a Taurus, and a Volvo. O1 will not drive an
Escort or a Nissan; O 2 will not drive a Taurus; O3 will not drive a Lexus or a
Volvo; O 4 will not drive a Lexus; and O5 will not drive an Escort or a Nissan. If
a feasible assignment of cars is chosen randomly, what is the probability that
(a) O1 gets the Volvo?
(b) O2 or O5 get the Volvo? (Hint: Model this constraint with an altered board.)
(a) The probability that O1 gets the Volvo is 3/10 .
(b) The probability that O2 or O5 will get the Volvo is 1/2 .
In the question ,
it is given that ,
the five officials : O1, O2, O3 , O4 , O5 are to be assigned five different city cars: a Escort, Lexus, Nissan, the Taurus, and the Volvo .
From the given data , the table formed is shown below .
From the table , we can observe that ,
O1 will not drive the Escort or a Nissan . So, he has chance of getting one car among Lexus, Taurus & Volvo = 3 possibilities
O2 will not drive the Taurus . So, he has chance of getting one car among Escort , Nissan ,Lexus, & Volvo = 4 possibilities
O3 will not drive the Lexus or Volvo . So, he has chance of getting one car among Escort , Nissan ,Taurus = 3 possibilities
O4 will not drive the Lexus so he has chance of getting one car among Escort , Nissan ,Taurus, Volvo = 4 possibilities
O5 will not drive the Escort or a Nissan . So, he has chance of getting one car among Lexus, Taurus & Volvo = 3 possibilities .
The 20 possible arrangements for E,L,N,T,V are :
{ (O2, O1, O3, O4, O5), (O2, O1, O3, O5, O4), (O2, O1, O4, O3, O5),
(O2, O5, O3, O1, O4), (O2, O5, O3, O4, O1),(O2, O5, O4, O3, O1),
(O3, O1, O2, O4, O5), (O3, O1, O2, O5, O4), (O3, O1, O4, O5, O2),
(O3, O2, O4, O1, O5), (O3, O2, O4, O5, O1), (O3, O5, O2, O1, O4),
(O3, O5, O2, O4, O1), (O3, O5, O4, O1, O2), (O4, O1, O2, O3, O5),
(O4, O1, O3, O5, O2), (O4, O2, O3, O1, O5), (O4, O2, O3, O5, O1),
(O4, O5, O2, O3, O1), (O4, O5, O3, O1, O2) }
Part(a) : The probability that O1 gets the Volvo is = 6/20 = 3/10 .
and
Part(b) :
Probability of O2 or O5 gets the Volvo = (Probability of O2 getting Volvo
) + (Probability of O5 getting Volvo) .
= 4/20 + 6/20
= 10/20 = 1/2 .
Therefore , the required probability for (a) is 3/10 and for (b) is 1/2 .

Sophie kicks a football. It’s height in feet is given by h(t) = -16t^2 + 16t where t represents the time in seconds after kick. How many seconds have give by when the football is at it highest point?
Answer:
The time at which the football reaches its highest point is 0.5 seconds.
Step-by-step explanation:
The height of an object thrown into the air is determined by the formula h(t) = -16t^2 + vt + h, where t represents the time in seconds after the object is thrown, v is the initial velocity with which the object is thrown, and h is the initial height from which the object is thrown. In this case, the initial velocity of the object is 16 feet per second and the initial height is 0 feet.
To find the time at which the football reaches its highest point, we need to find the value of t that makes the value of h(t) maximum. This value of t can be found by taking the derivative of the equation h(t) and setting it equal to 0. The derivative of h(t) is given by h'(t) = -32t + 16. Setting h'(t) equal to 0, we get -32t + 16 = 0, which can be solved to get t = 0.5 seconds.
Therefore, the time at which the football reaches its highest point is 0.5 seconds.
Which inequality is true when z = 9
When x = 9, the inequality - 4 + x ≤ 9 has the necessary value.
What is meant by inequality?In mathematics, an inequality displays the connection between two values in an unbalanced algebraic statement. One of the two variables on the two sides of the inequality may be greater than, greater than or equal to, less than, or less than or equal to another value, according to inequality signals.
Mathematics that contains at least two terms with variables or integers that are not equal is referred to as being unequal.
Inequality, two integers or algebraic expressions with a declared order link (greater than, greater than, or equal to, less than, or less than or equal to).
As per option (B),
When substituting the values the equation -4 + 9 is less than or equal to 5.
-4 + 9 is 5 so this equation is true
