The probability of a customer who gets one piece of fruit from the bowl randomly choosing an orange or a pear is 21/36

What is Probability ?

Probability can be defined as the ratio of number of favourable outcomes and total number of outcomes

Given ,

A bowl at a delicatessen contains a mix of 15 apples, 12 oranges, and 9 pears

so , we have to find  the probability of a customer who gets one piece of fruit from the bowl randomly choosing an orange or a pear.

Choosing orange or a pear ,

= 12c1 + 9c1

= 12+9

= 21

Total = 36.

Probability = 12 + 9 / 36

= 21 / 36 .

Therefore , The probability of a customer who gets one piece of fruit from the bowl randomly choosing an orange or a pear is 21/36

A cosine and sine function can be expressed in terms of an imaginary exponential using Euler's formula: e^(iθ) = cos(θ) + i*sin(θ).

This formula can be derived by using the Taylor series for e^x, and replacing x with iθ.

A cosine and sine function can be expressed in terms of an imaginary exponential using Euler's formula: e^(iθ) = cos(θ) + i*sin(θ).

Conversely, an imaginary exponential can be expressed in terms of cosine and sine by solving for θ in the above equation. This can be done by taking the inverse cosine and inverse sine of both sides to get θ = cos^(-1)(e^(iθ)) = sin^(-1)(i*sin(θ)). Combining these equations gives θ = sin^(-1)(i*(e^(iθ) - cos(θ))).

The linear function that models the graph is given as follows:

a) y = -2x/3 - 4.

The slope-intercept definition of a linear function is given as follows:

y = mx + b.

In which:

The graph crosses the y-axis at y = -4, hence the intercept b is obtained as follows:

b = -4.

When x increases by 6, y decays by 4, hence the slope m is obtained as follows:

True. The three numbers can be the measures of the sides of a triangle.

What is the triangle inequality theorem?

The triangle inequality theorem is a fundamental principle in Euclidean geometry that states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. This means that in any triangle, no side can be longer than the sum of the other two sides.

The three numbers 4, 7, and 8 can be the measures of the sides of a triangle. This is because of the triangle inequality theorem which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. In other words, for any triangle, the sum of two sides must always be greater than the third side.

For example, in this case,

4 + 7 = 11 > 8,

7 + 8 = 15 > 4,

4 + 8 = 12 > 7

Hence, 4, 7, and 8 can be the measures of the sides of a triangle, so the correct response would be "True".

Simple interest is an amount which is calculated for a certain period of time and for a certain rate, in simple interest calculation there are three factors which we consider: principal amount(P), rate(R) and time(T).

Every time we calculate simple interest the principal values will be the same unlike compound interest.

Formula;    Simple Interest(I) =  P × R × T/100

Given that,

Offer 1-  5.99% annual simple interest, with a total account balance of $32,487.50 after a 60-month term Offer

Offer 2-  3.75% annual interest compounded monthly for a 66-month term

In offer 1,

Total amount A  = $32487.50

In offer 2,

Total amount =

[tex]A = P[ 1 + r/n]^{nt}[/tex]

[tex]A = 25000[ 1 + 0.0375/12]^{12*5.5}[/tex]

A = $30,716.63

Difference = 32487.50 - 30716.63

Answer:

w = 0, z = − 2

Step-by-step explanation:

The solution for the given system of equations is: w = 0 and z = -2.

What is a system of equations?

A system of equations is a collection of two or more equations with the same set of unknowns. For a system to have a unique solution, the number of equations must equal the number of unknowns.

The equations are as follows:

[tex]3w-4z=8[/tex]-------- (1)

[tex]2w+3z=-6[/tex]-------(2)

The solution for the above equation,

Multiply the equation 1 by 2,

⇒([tex]3w-4z=8[/tex]  )*2 --------- (3)

Multiply the equation 2 by 3,

⇒([tex]2w+3z=-6[/tex] )*3 --------(4)

Now solve equations 3 and 4 to get,

⇒ [tex]-17z=34[/tex]

⇒ [tex]z= -2[/tex]

Now substitute the value of z in equation 1,

⇒  [tex]3w-4(-2)=8[/tex]

⇒ [tex]\\3w=0[/tex]

⇒ [tex]w=0\\[/tex]

Hence we can conclude that the solution for the given system of equations is w = 0 and z = -2.

The figure of the coterminal angle of 300° on a circle in standard position is attached in the solution.

Coterminal angles are angles in standard position (angles with the initial side on the positive x-axis) that have a common terminal side.

Coterminal angles are two angles in the standard position where one angle is a multiple of 360 degrees larger or smaller than the other. That is, if angle A has a measure of M degrees, then angle B is co-terminal if it measures M +/- 360n, where n=0,1,2,3, ...

Starting from that position, 300° is drawn by moving around the circle to the left "counter-clockwise" and ending at the 300° measure.

The negative coterminal angle is the angle that would end in the same place if we went to the right instead of right on the circle. It is equal to the original 300° minus 360°

Coterminal angles Ac to angle A may be obtained by adding or subtracting k⋅360° or k × (2π)

Hence, Ac = A + k⋅360°, if A is given in degrees.

Answer:

The two numbers are 17 and 7

Step-by-step explanation:

Translate this word problem into a math equation

If we let x and y be the two unknown numbers

One-half the sum of two numbers is 12 ==>

So one equation is 1/2(x + y) =12

Multiplying throughout by 2 gets rid of the denominator:
2 x 1/2 x (x + y) = 2 x 12

x + y = 24   (1)

One of the numbers is three more than two times the other number:
x = 2y + 3

or

x - 2y = 3  (2)

Equation (2) - Equation (1) =>

x + y - (x -2y) = 24 - 1
x + y - x + 2y = 21

3y = 21

y = 21/3

y = 7

With y = 7, substituting in equation 1 gives

x + y = 24

x + 7 = 24

x = 24-7

x = 17

The two numbers are 17 and 7

According to the Greek geocentric paradigm, a planet moves retrogradely when it actually goes backward in its orbit around Earth. So the option b is correct.

The geocentric paradigm, also known as geocentrism, which is frequently and particularly shown by the Ptolemaic system, is an outdated explanation of the cosmos that places Earth at its center. The Sun, Moon, stars, and planets all orbit Earth according to the majority of geocentric models.

Since humans have been gazing up at the stars for thousands of years, our perception of what the Universe looks like has undergone a significant transformation.

In time, humanity also realized that the Earth was a sphere and developed logical justifications for how other heavenly bodies behaved. By classical antiquity, scientists had developed theories about how the planets moved and how all the celestial bodies interacted. This led to the development of the now-defunct Geocentric model of the cosmos, which described how the Sun, Moon, and firmament revolved around our earth.
