The probability that someone who tests negative does not have the disease is 0.8451

Given that,

The information shows the outcomes of a test for a specific illness. Assume a member of the group is chosen at random.

From given data table,

N = 144+ 22 + 14+ 120 = 300

n(not disease) = 22 + 120 = 142

n( negative And not disease) = 120

P( Not disease) = 142/300

P( Negative and not disease) = 120/300

Therefore,

P(Negative/ not ..disease) =[tex]\frac{P(Negative and not,.disease)}{P(Not ,.disease)}[/tex]

                                                                 =[tex]\frac{120/300}{142/300}[/tex]

                                                                  =[tex]\frac{120}{142}[/tex]

                                                                   =0.8451

Hence, The probability approximately is 0.8451

Hence, the probability that someone who tests negative does not have the disease is 0.8451

The measure of the angle I= is 50 degree

A triangle has three sides and a total interior angle of 180 degrees. Four-sided shapes like a square, rectangle, or quadrilateral have a total interior angle of 360 degrees. Other polygons have different angles and different numbers of sides, such as the pentagon, hexagon, heptagon, and octagon.

Compared to algebra, geometry requires less math, and the math that is needed is simpler. Geometry, on the other hand, necessitates the memorization of numerous rules and formulas, which for some students can be more challenging than fundamental algebra. Ask your teacher for assistance if you need it in a math class.

The ratio of the respective sides is proportional when two triangles are comparable to one another.

Additionally, the corresponding angles coincide.

Given in this case are B= 35° and C= 95°

the angle sum property now

A + B + C = 180°

A + 35 + 95 = 180

A + 130 = 180

130 is subtracted from both sides, giving us

A = 180 - 130

A = 50°.

Now

ABC and LMN

Consequently, in terms of similarity

A = L

But A = 50°.

Thus, L = 50°.

The interest rate is -42.3%, where the negative sign indicates depreciation.

The percentage that a lender adds to the amount of money lent to them is called an interest rate.

Given that, the investment of $1800 in the stock market is $278 in two years.

Therefore, the amount depreciated is:

278 - 1800

= -1522

Since 1522 is depreciated in 2 years, the amount depreciated in one year is:
1522/2

= 761

The rate at which the amount depreciated is:

(761/1800)×100%

= 42.3%

Hence, the interest rate is -42.3%, where the negative sign indicates depreciation.

A 15 square metres sector will have a radius of 8.1 m and a central angle of 26.04 degrees.

The region of a disk encompassed by two radii and an arc is called a circular sector, also known as a circle sector or disk sector. The smaller area is referred to as the minor sector, and the larger area as the major sector. A sector is referred to as a component of a circle made up of the circle's arc and its two radii. It is a section of the circle made up of the arc's circumference and the radii of the circle at its ends. A slice of pizza or a pie can be used as an analogy for the form of a circle's sector.

Step-by-step explanation:

remember, an exponent n just means that the base is multiplied by itself n times.

so, e.g.

a³ = a×a×a = (a×a)×a

a⁶ = a×a×a×a×a×a = (a×a)×(a×a)×(a×a)

as you can see, any even exponent can be written as products of squares.

and any odd (uneven) exponent can be written as product of squares multiplied by one base.

a square of a real number is always positive. therefore, an even exponent of a real number is always positive.

and an odd exponent has the sign of the base (as the result of these multiplications is the product of the squares, that are always positive and one instant of the base, and +×+ = +, +×- = -).

and 1^n = 1

no matter how often I multiply 1 by 1, I get 1 as result.

also : -×- = +

1.

f(x) = x^n, n is even

f(1) = 1^n = (1×1)×(1×1)×...×(1×1) = 1×1×1×...×1 = 1

f(-1) = (-1)^n = (-1×-1)×(-1×-1)×...×(-1×-1) = 1×1×1×...×1 = 1

2.

g(x) = x^n, n is odd

g(1) = (1×1)×(1×1)×...(1×1)×1 = 1×1×1×...×1×1 = 1

g(-1) = (-1×-1)×...×(-1×-1)×-1 = 1×1×...×1×-1 = -1

What do you mean by probability?

Mathematical explanations of the likelihood that an event will occur or that a statement is true are referred to as probabilities. A number between 0 and 1 represents the likelihood of an event, with 0 generally denoting impossibility and 1 denoting certainty.

According to data in the given question,

We have the given information:

The number of sports magazines = 25

The number of news magazines = 11

The number of travel magazines = 2

Now, we will calculate the probability of the magazine is a sports magazine,

Total number of magazine = 25+11+2 = 38

To find the probability that the random selected magazine is a sports magazine divide the amount of sports magazines by the total amount of magazines:

P( sports magazine ) = Number of sports magazine/Total number of magazine

Answer:

The answer is -x^2-4x

Step-by-step explanation:

Random variable

a. E (X+ Y) = 14.10

   E|(X – Y)| = 5.1

b. E[max(X ,Y )] = 9.60

   E[min(x, y)] = 4.5

Conversely, once Y=y is observed, we would more likely be interested in the quantity E(X∣Y=y)=ρy which is a scalar.

Maybe this seems like needless complication, but regarding E(X∣Y) as a random variable in its own right is what makes things like the tower-law E(X)=E[E(X∣Y)] make sense - the thing on the inside of the braces is random, so we can ask what its expectation is, whereas there is nothing random about E(X∣Y=y).

a. E (X+ Y)

=∑∑( x +y)p(x ,y)

= (0+0)(0+2) + (0 + 5)(.06) + … + (10 + 15)(.01)

= 14.10

E|(X – Y)| = ∑∑ |x – y| p(x,y)

= |(0-0)|(0.02) + |(0-5)|(0.06) + ……+ |(10-15)|(0.01)

= 5.1

b.

E[max(X ,Y )] = ∑∑max(x+y).p (x ,y)

= (0)(.02) + (5)(.06) +…+(15)(.01)

E[min(x, y)] = ∑∑ min (x,y) p(x,y)

Step-by-step explanation:

If $10,000 is invested at x percent simple annual interest for n years, the total amount of interest would be F = 10,000n(x/100)

Simple interest is calculated based on the principle of a loan or the initial deposit into a savings account. Simple interest doesn't compound, so a creditor will only charge interest on the principal sum, and a borrower will never be required to pay interest on interest that has already accrued.

F = P(1+rt), formula for simple rate of interest

Here,

=> Future value is F

=> Present value is P

=> Rate is R

=> Time is t

Substituting x for r

And, n for t

Also, 10,000 in for P

F = 10,000(1+xn)

The formula tells us principal + interest,

F = 10,000(xn)

Now, to get the x into terms of a percentage,

F = 10,000(n * x/100)

F = 10,000n(x/100)

The point in which the three medians of the triangle intersect is known as the centroid of a triangle. It is also defined as the point of intersection of all the three medians. The median is a line that joins the midpoint of a side and the opposite vertex of the triangleCentroid theorem: the distance between the centroid and its corresponding vertex is twice the distance between the barycenter and the midpoint of the opposite side. That is, the distance from the centroid to each vertex is 2/3 the length of each median. This is true for every triangleThe centroid of a triangle is the intersection of the three medians of the triangle (each median connecting a vertex with the midpoint of the opposite side).

The sales price of the coat is 67.5% of the original price

From the question, we have the following parameters that can be used in our computation:

Markdown rate = 10%

Second discount = 25%

The retail price of the coat can be calculated using the following equation

Retail price = original price * (1 - Markdown rate) * (1 - discount)

Substitute the known values in the above equation, so, we have the following representation

Retail price = original price * (1 - 10%) * (1 - 25%)

Evaluate the products

Retail price = original price * 0.675

Rewrite as

Retail price = 67.5% of the original price

Hence, the sales price is 67.5% of the original price

The required maximum volume of the box would be 85184 cube units.

The surface area of a box is the total area of all of the box's faces. For a box with a square base and no top, the surface area is equal to the sum of the areas of the four sides and the bottom.

To find the maximum volume of such a box, we can first find the length of one side of the square base. We can do this by dividing the given surface area by the number of sides of the box.

In this case, the box has 4 sides plus the bottom, so the length of one side is 220 / 5 = 44.

We can now use the length of one side to find the maximum volume of the box. The volume of a box with a square base and no top is equal to the length of one side cubed.

The length of one side is 44, so the maximum volume of the box is :

⇒ 44 × 44 × 44  = 85184.

Therefore, the maximum volume of the box is 85184 cube units.
