The probability of selecting 2 red marbles in a row is 1/12.

A bag contains 6 blue marbles, 5 red marbles, 3 green marbles, and 2 yellow marbles. Two marbles are removed from the bag one at a time without being replaced. We need to find the probability of selecting 2 red marbles in a row. Let the probability be represented by the variable "P".

The probability that the first selected marble will be red is given below :

P1 = 5/(6 + 5 + 3 + 2) = 5/16

The probability that the second selected marble will be red is given below :

P2 = 4/(6 + 4 + 3 + 2) = 4/15

The probability that both of the selected marbles will be red is given below :

P = P1*P2 = (5/16)*(4/15) = 1/12.

Answer:

12100

Step-by-step explanation:

If the number B of federally insured banks could be approximated by B ( t ) = − 329.4 t + 13747 from 1985 to 2007 where t = 0 correspond to year 1985

In order to determine the amount of federally insured banks that were there in 1990, we will first calculate the year range from initial time 1985 till 1990

The amount of time during this period is 5years. Substituting t = 5 into the modeled equation will give;

B ( t ) = − 329.4 t + 13747

B(5) = -329.4(5) + 13747

B(5) = -1647+13747

B(5) = 12100

This shows that there will be 12100 federally insured banks are there in the year 1990.

The height of a can of fruit juice used as a prop, if it's actual height is 7 inches, should be of:

3.85 inches.

A proportional relationship is a linear function that has intercept of zero and hence it has the output variable y as the multiplication of the input variable x and the constant of proportionality k, as follows:

y = kx.

The input and the output variables in this problem are given as follows:

From the table given at the end of the answer, the constant is given as follows:

k = 44/80

k = 0.55.

Hence the equation is:

y = 0.55x.

Then the height on the set when the actual height is of 7 inches is given by:

y = 0.55(7) = 3.85 inches.

The table is given by the image at the end of the answer.

Linear equations are mathematical equations of the type y = mx + b, with   and x and y being variables. These equations represent a straight line on a graph and are referred to be "linear" since the maximum power of the variable is 1. For example, the equation y = 2x + 3 is a linear equation since the maximum power of the variable x is 1. Linear equations are useful for representing a broad range of real-world events, such as the link between the distance an object travels and the time it takes to traverse that distance. They are a common tool in many disciplines, including physics, engineering, and economics. They are also quite simple to answer.

Answer:y

=5/4x+-3

Step-by-step explanation:

first you find the slope which is 5/4 then you do y=mx+b but replace the y and the x with points on the line giving you 2=5/4•4+b then you solve for b and get -3 giving you your answer.

Answer: -5/4x+7

Step-by-step explanation:

1)First find the slope passing through (8,-3) (4,2) using this formula

y2-y1/x2-x1 (this: 2--3/4-2) to get -1.25 or -5/4. this is your slope.

2) Then to get the y-intercept choose one of your points (doesn't matter which I chose (8,3) but you can choose any of the two) and create this formula y=mx+b.

3) Input your x and y from the point you chose and your slope (m) to create this -3=(8)+b.

4) Now solve for b. This should get you Postitve 7 (REMEMBER it is VERY IMPORTANT if you result is negative or positive. One mess up could make the whole thing wrong.)

5) Finally take your slope and y-intercept and put it together to get:

y=-5/4x+7

The probability of getting 3 on both of the dice is 1/36.

What is probability?

Mathematical explanations of the likelihood that an event will occur or that a statement is true are referred to as probabilities. An event's possibility is a number between 0 and 1, where, practically speaking, 0 denotes the event's impossibility and 1 denotes certainty.

Main Body:

The probability of getting 3 on a dice = 1/6

As Jemmy throws the dice twice

P( 3 on both dice) =(1/6)*1/6

P ( 3 on both dice) = 1/36.

Hence the probability of getting 3 on both dice = 1/36.

10 blocks are the shortest distance between Caroline and Mattie's homes.

Given data,

Caroline steps outside and makes a 6 block trek to the north. To go to Mattie's house, she does a turn and travels 8 blocks to the east.

To get the shortest distance between Caroline and Mattie's houses we need to it as a triangle and apply the Pythagorean theorem.

Pythagorean theorem:

The well-known geometric axiom is that the hypotenuse (the side across from the right angle) of a right triangle is equal to the sum of the squares on its legs. Or, in popular algebraic form, a² + b² = c².

The shortest distance (c);

Let, a = 6

      b = 8

⇒ a² + b² = c²

   6² + 8² = c²

   36 + 64 = c²

What is consecutive interior angles?

Pairs of angles that are between two lines and on the same side of the line that cuts through the lines are referred to as consecutive internal angles.

The "consecutive interior angle theorem" asserts that each pair of consecutive interior angles is supplementary, meaning that the sum of the consecutive interior angles equals 180°, if a transversal intersects two parallel lines.

Here to make m ║n  the angles x and 2x are consecutive interior angles.

Since consecutive interior angles are supplementary.

So,

x + 2x = 180

3x = 180

x = 180/3

x = 60 degree.

Therefore, the value of x is 60 degree that makes m ║n.

[tex]\left(sec(x) = \dfrac{1}{cos(x)}\right)[/tex]  and [tex]\left(csc(x) = \dfrac{1}{sin(x)}\right)[/tex] to give the following

trigonometric identity;

Trigonometric identities are equations of trig functions which are valid for all values of the input variable at which the expressions on both sides of the equality are defined.

The trigonometric expression in the question is simplified as follows;

[tex]\dfrac{tan( x)}{1+sec( x)} +\dfrac{1+sec( x)}{tan( x)} = \dfrac{tan( x)}{1+\dfrac{1}{cos(x)} } +\dfrac{1+\dfrac{1}{cos(x)}}{tan( x)}[/tex]

[tex]\dfrac{tan( x)}{1+\dfrac{1}{cos(x)} } +\dfrac{1+\dfrac{1}{cos(x)}}{tan( x)} = \dfrac{cos(x)\times tan( x)}{cos(x)+1} } +\dfrac{cos(x)+1}{cos(x)\times tan( x)}}[/tex]

[tex]\dfrac{cos(x)\times tan( x)}{cos(x)+1} } +\dfrac{cos(x)+1}{cos(x)\times tan( x)}} = \dfrac{sin(x)}{cos(x)+1} } +\dfrac{cos(x)+1}{sin( x)}}[/tex]

[tex]\dfrac{sin(x)}{cos(x)+1} } +\dfrac{cos(x)+1}{sin( x)}} = \dfrac{sin^2(x)+(cos(x)+1)^2}{sin( x)\cdot (cos(x)+1)} }[/tex]

[tex]\dfrac{sin^2(x)+(cos(x)+1)^2}{sin( x)\cdot (cos(x)+1)} }=\dfrac{sin^2(x)+cos^2(x)+2\cdot cos(x)+1}{sin( x)\cdot (cos(x)+1)}[/tex]

[tex]\dfrac{2\cdot cos(x)+2}{sin( x)\cdot (cos(x)+1)} =\dfrac{2\cdot (cos(x)+1)}{sin( x)\cdot (cos(x)+1)} = \dfrac{2}{sin( x)}[/tex]

[tex]\dfrac{2}{sin( x)} = 2\cdot csc(x)[/tex]

The answer, Arianna's battery, as a percentage, 3.75t hours after Arianna left her house.

What is percentage?

A percentage that represents a tenth of a quantity. One percent, denoted by the symbol 1%, is equal to one-hundredth of something; hence, 100 percent denotes the full thing, and 200 percent designates twice the amount specified. A portion per hundred is what the percentage denotes. Percentage refers to one in a hundred. The % sign is used to denote it.

The initial charge of Arianna's phone = 45%

now the charge remaining in Arianna's battery = 15%

If after 4 hours of leaving her house, the battery had 15% remaining battery life, then the battery is discharging at the rate of ( 15% / 4 hours)

=3.75% per hour.

Thus, the charge remaining in Arianna's battery after she left her house will be, B = 3.75t
