The measures of the unknown angles are

x = 46

and

y = 88

From the question, we are to determine the measures of the unknown angles in the triangle.

From the diagram, we can observe that the triangle is an isosceles triangle as the legs of the triangle are congruent to each other.

Since the triangle is an isosceles triangle, the base angles of the triangle must be equal

The base angles are 46° and x°

Thus,

x = 46

Also,

We can write that

y° + 46° + x° = 180° (Sum of angles in a triangle)

y° + 46° + 46° = 180°

y° + 92° = 180°

y° = 180° - 92°

y° = 88°

Thus,

y = 88

Hence, x = 46 and y = 88

The income plainness of demand for eatery reflections is Income plainness = 200/ 20 = 10

Chance is a way of expressing a volume as a bit of 100. It's frequently denoted using the percent symbol(), which represents" per hundred". For illustration, 25 is original to25/100 or0.25 as a numeric.

By question-

The income plainness of demand measures the responsiveness of the volume demanded of a good or service to a change in income, all other effects being equal .However, it means that the good is a normal good, and the volume demanded increases as income increases, If the income plainness is positive. However, it means that the good is an inferior good, and the volume demanded diminishments as income increases, If the income plainness is negative.

In this case, John's pay increased by 20 percent, and the average number of eatery reflections he consumed increased from one a week to three a week. We can calculate the income plainness of demand for eatery reflections as follows

Income plainness = chance change in volume demanded/ chance change in income

The chance change in volume demanded is

( 3 reflections per week- 1 mess per week)/ 1 mess per week) x 100 = 200

The chance change in income is 20

thus, the income plainness of demand for eatery reflections is

Income plainness = 200/ 20 = 10

Since the income plainness is positive and lesser than 1, we can conclude that eatery reflections are a luxury good for John. Option( b) is the correct answer.

The solution set of the system of linear inequalities is the shaded region.

What is the system of linear inequalities?

A system of linear inequalities is a set of two or more linear inequalities that involve the same variables. Linear inequalities are mathematical statements that compare two expressions using the inequality symbols (<, >, ≤, or ≥) and indicate that one expression is less than or greater than another.

A system of linear inequalities can be represented graphically as a collection of shaded regions on a coordinate plane. The solution set of the system is the intersection of all shaded regions that satisfy all the inequalities in the system.

To find the solution set of the system of linear inequalities:

y < 3 + (1/2)x

y > 6 - (2/3)x

We can start by graphing each inequality on the same coordinate system. To do this, we can start by finding the x and y-intercepts of each inequality.

For the first inequality, y < 3 + (1/2)x, we can set x = 0 to find the y-intercept:

y < 3

So the y-intercept is at (0, 3).

Next, we can set y = 0 to find the x-intercept:

0 < 3 + (1/2)x

-3 < (1/2)x

-6 < x

So the x-intercept is at (-6, 0).

We can plot these points and draw a dashed line connecting them, since the inequality is strict (y < 3 + (1/2)x):

Attachment 1

For the second inequality, y > 6 - (2/3)x, we can set x = 0 to find the y-intercept:

y > 6

So the y-intercept is at (0, 6).

Next, we can set y = 0 to find the x-intercept:

0 > 6 - (2/3)x

6 > (2/3)x

9 > x

So the x-intercept is at (9, 0).

We can plot these points and draw a dashed line connecting them, since the inequality is strict (y > 6 - (2/3)x):

Attachment 2

Now, we need to determine which region of the graph satisfies both inequalities. We can do this by testing a point in each region. For example, we can test the point (0,0):

y < 3 + (1/2)x is true, since 0 < 3 + (1/2)(0)

y > 6 - (2/3)x is false, since 0 > 6 - (2/3)(0)

Therefore, the region below the first line but above the second line satisfies both inequalities. We can shade this region:

Attachment 3

So the solution set of the system of linear inequalities is the shaded region.

The dolphin traveled a total vertical distance of 17 feet during its jump. Note that the negative sign for the second and third parts of the jump indicates that the dolphin was descending during those parts.

Distance is the total amount of space traveled by an object or a person, regardless of the direction taken. It is a scalar quantity and is usually measured in units such as meters (m), kilometers (km), feet (ft), or miles (mi). Distance is different from displacement, which is the shortest distance between the starting and ending points in a particular direction.

The total vertical distance the dolphin traveled is the sum of the distances it traveled during each part of the jump:

Distance traveled during the first part of the jump (underwater to the surface): 27 feet - (-35 feet) = 62 feet

Distance traveled during the second part of the jump (out of the water to the surface): 0 feet - 27 feet = -27 feet

Distance traveled during the third part of the jump (surface to underwater): -18 feet - 0 feet = -18 feet

Total vertical distance traveled: 62 feet + (-27 feet) + (-18 feet) = 17 feet

Therefore, the dolphin traveled a total vertical distance of 17 feet during its jump. Note that the negative sign for the second and third parts of the jump indicates that the dolphin was descending during those parts.

THE minimum score required to be in the top 4% of exam scores is 87.08 points, which is option A. To determine the minimum score required to be in the top 4% of exam scores, we can use the standard normal distribution and the Z-score formula.

First, we need to find the Z-score associated with the top 4% of exam scores. The Z-score represents the number of standard deviations above or below the mean a particular value falls. We can use a standard normal distribution table or calculator to find that the Z-score corresponding to the top 4% is approximately 1.75.

Next, we can use the Z-score formula to find the minimum score required to achieve a Z-score of 1.75:

Z = (X - μ) / σ

where X is the minimum score required, μ is the mean of exam scores, and σ is the standard deviation of exam scores.

Rearranging the formula to solve for X, we get:

X = Z {multiply} σ + μ

Plugging in the values we have, we get:

X = 1.75 {multiply}6.1 + 76.4

X = 87.08

Therefore, the minimum score required to be in the top 4% of exam scores is 87.08 points, which is option A.

(a) Let X be the number of people out of 20 who have the XBB.1.5 variant. X follows a binomial distribution with parameters n=20 and p=0.7. We need to find the probability that at most 12 out of 20 randomly chosen people in NYC who have COVID have this specific variant, which can be expressed as P(X ≤ 12).

Using a binomial distribution table or a calculator, we can calculate:

P(X ≤ 12) = ΣP(X=k), for k=0 to 12

P(X ≤ 12) =  0.2277

Therefore, the probability that at most 12 out of 20 randomly chosen people in NYC who have COVID have the XBB.1.5 variant is approximately 0.2277.

(b) Let Y be the number of patients tested until exactly 5 are found to have the XBB.1.5 variant. Y follows a negative binomial distribution with parameters r=5 and p=0.7. We need to find the probability that one must test 8 or more COVID patients in order to find exactly 5 that have the new variant, which can be expressed as P(Y ≥ 8).

Using the negative binomial distribution formula, we can calculate:

P(Y ≥ 8) = ΣP(Y=k), for k=8 to infinity

P(Y ≥ 8) = Σ [(k-1) choose (r-1)] p^r (1-p)^(k-r), for k=8 to infinity

This is a tedious calculation to do by hand, but we can use a calculator or software to find that P(Y ≥ 8) ≈ 0.99872

Completing the square is a mathematical technique used to manipulate quadratic equations into a standard form that makes them easier to solve

The general form of a quadratic equation is:

ax^2 + bx + c = 0

To complete the square, you need to add and subtract (b/2a)^2 to the left side of the equation. This is because (b/2a)^2 is equal to (b/2a) times itself, which means it is a perfect square.

Here is the formula for completing the square:

ax^2 + bx + c = 0

ax^2 + bx = -c

a(x^2 + (b/a)x) = -c

a(x^2 + (b/a)x + (b/2a)^2 - (b/2a)^2) = -c

a(x + b/2a)^2 = -c + (b/2a)^2

The equation is now in the standard form:

a(x + b/2a)^2 = (4ac - b^2)/4a

By taking the square root of both sides, you can solve for x:

x = (-b +/- sqrt(b^2 - 4ac))/2a

This is the quadratic formula, which gives you the values of x that make the equation equal to zero.
