Which numbers are solutions of 4p+6<3p? Choose exactly two answers that are correct ​

To solve this problem, we will use the conditional probability definition: Given events A,B such that P(B)>0 we have that

Where P(A|B) means the probability of A given B occurred. This also leads to the following

Now, let us define two events. Let M1 be the event that we select a male first and let F2 be the event that we select a female second. We want to calculate the following probabilty

Using the definition of conditional probability, this is the same as

Now, we will calculate P(M1). At the beginning, when we have not picked anyone yet, we have 37 people (21 Female and 16 Male). So the probability of picking a male first is simply

Now, we will calculate the second probability. Since we already picked one male, we have now 36 people (21 female and 15 male). Then the probability of picking a female is

the two triangles have a bisetor that makes the adjacent side equal, so based on this 25 = 5x- 10

25+ 10 = 5x

meaning your x = 7

but on the equation 5x-10 =0

we get that x = 10/5

x >2

so the range would be 2

Answer:

The small box price is 6.5 and The large box price is 16.5

Step-by-step explanation:

I did the question with a simultaneous equation

let's say the price of the small box = x and the price of the large box = y

Then, I just subtract downward;

18x+25y=529.50

- 18x+10y=282.00

_____________

0+15y=247.50

15y=247.50

— ————

15 15

I just canceled 15 by 15:

Then, y=247.50÷15=16.5

so I just find the value of Y which is 16.5, then I insert it into the second equation:

18x+10y=282

18x+10(16.5)=282

18x+165=282

18x=282-165

18x=117

The system of equations for the given conditions in question includes equation: 3.40 = 0.05x + 0.1y + 0.25z, and 2x = z. and we have 2 nickels, 23 dimes, and 4 quarters.  

What is system of equations?

A system of equations is a collection of some equations with one or more numbers of variables. Systems of equations have solutions that are either the variable mappings that satisfy each component equation or the intersections of all of these equations.

Let the quantities of nickels, dimes, and quarters are x, y, and z respectively.

We know that, 1 nickel = $0.05, 1 dime = $0.1, and 1 quarter = $0.25

So, the values of nickels, dimes, and quarters would be value of one times total quantity.

Nickels = 0.05x, dimes = 0.1y, and quarters = 0.25z

As given in the question, the total value is 3.40

So, we get equation:

3.40 = 0.05x + 0.1y + 0.25z

Also it is given that there are twice as many nickels than quarters.

2x = z

Combining above two equations

3.40 = 0.05x + 0.1y + 0.25(2x)

3.40 = 0.05x + 0.1y + 0.5x

3.40 = 0.55x + 0.1y

Lets put 2 in place of x, we get y

(3.40 - 1.1)0.1 = y

y = 23.

Now, putting values of x, y in equation to get value of z

3.40 = 0.05(2) + 0.1(23) + 0.25z

3.40 = 0.1 + 2.3 + 0.25z

(3.40 - 2.4)/0.25 = z

z = 4

Therefore, we have 2 nickels, 23 dimes, and 4 quarters.

Using probability we can calculate that the company must charge $697 for an expected return of 400 .

Probability is a branch of mathematics that deals with numerical representations of the likelihood of an event occurring or of a proposition being true. The probability of an event is a number between 0 and 1, with 0 approximately denoting impossibility and 1 denoting certainty.

The probability that a 30 year old female lives throughout the year

= 0.99967

Death benefit = $900,000

Expected amount the company would pay = probability that a person dies × insurance amount.

Expected amount = (1 - 0.99967) × 900000 = $297

Now Company wants a profit of $400

Cost charged by company =$( 297 + 400 ) = $ 697

The coordinates of the vertices of the image triangle A'B'C' after a rotation 90° counterclockwise about the origin are: A' (10, 5), B' (-4, -8), C'(0, 2)

A rotation simply refers to a type of transformation which moves every point of the object through a number of degrees around a given point, which can either be clockwise or counterclockwise (anticlockwise) direction.

In Geometry, rotating a point 90° about the origin in a counterclockwise (anticlockwise) would produce a point that has the coordinates (-y, x).

By applying a rotation of 90° counterclockwise to triangle ABC, the coordinates of the vertices of the image triangle A'B'C' include the following:

(x, y)                    →            (-y, x)

Point A = (5, -10)   →  Point A' = (-(-10), 5) = (10, 5)

Point B = (-8, 4)   →    Point B' = (-4, -8)

The features of the graphs are

Function 1

The equation of the function is given as

f(x) = 3(x - 4)^2 + 3

A quadratic equation can be represented as

f(x) = a(x - h)^2 + k

Where, the vertex is

Vertex = (h, k)

And the axis of symmetry is

x = h

By comparing the equations, we have

Vertex = (4, 3)

Axis of symmetry: x = 4

See attachment 1 for the graph of the function

Function 2

The equation of the function is given as

f(x) = 5x^2 + 4x - 1

Differentiate the function

f'(x) = 10x + 4

Set to 0

10x + 4 = 0

This gives

x = -0.4

Substitute x = -0.4 in f(x) = 5x^2 + 4x - 1

f(-0.4) = 5(-0.4)^2 + 4(-0.4) - 1

Evaluate

f(-0.4) = -1.8

This means that

The volume of a right cone is one-third of the product of the area of the base B and the

Since the area of the base and the height is already given, substitute the values in to the equation and then simplify.

We may also find the exact value by substituting the given values into the equation below.

where V is the volume, r is the radius, and h is the height.

To obtain the exact value of the height, we use the Pythagorean theorem.

where a and b are the legs of the formed right triangle while c is its hypothenuse.

From the figure, the slant height is the hypothenuse while the radius, 9 ft, serve as one of the legs. Thus, the other leg, which is the height of the cone can be solved as follows.

Therefore, the height of the cone is as stated above.

Substitute the obtained height and the radius into the second formula that was stated.

Simplify the right side of the equation. Evaluate the exponential expression.

Multiply the numerator and then divide it by 3.

Note that the value that we obtain at first, 1415,603, is slightly different from the one that we obtained, which is 1419.36, since there are values that we already rounded off before substituting the values in the equation.

Therefore, to be more exact, it is best to indicate that the volume of the given cone is approximately 1419.36 ft³.

The principal amount is $693.33.

Simple interest is a quick and simple approach to figure out how much money has accrued interest. Interest is always applied to the original principal amount and is calculated at the same rate for each period of time. Any bank where we deposit money will pay us interest on that amount.

The formula is

Simple Interest = P x R x T/100

Given:

Interest = 78

Rate= 7.5%

Time= 1 and half year = 1.5 year

Now, Simple Interest= P x R x T / 100

                             78 = P x 7.5 x 1.5 / 100

                             7800= P x 11.25

                             P = 7800/11.25

                              P = 693.33
