what is neagtive four equal r over twenty minus five

Answer:

14/885 or 1.58%

Step-by-step explanation:

In total, there are 60 marbles. The probability of drawing a blue marble the first time is 8/60. If you keep the one blue marble that was drawn, the total number of marbles in the bag is 59, and there are now 7 blue marbles. The probability of drawing a blue marble now is 7/59.

In order to find out the total probability of drawing two blue marbles in a row, you need to multiply these two fractions.

(8/60) x (7/59) = 56/3540 = 14/885 (approx. 1.58%)

Hope this helps!

Answer:

See attached image.

Step-by-step explanation:

Since the number of termites in a colony starts out with 125 insects and increases by 75% each week we are looking for a graph where the line crosses the y-axis (vertical axis) at 125 and continues to increases by 75%.

From the screenshots given only one graph has a line that intersects at 125 on the y axis and continues upward (see attached image). The other graphs depict a beginning number of termites of 875, 0, and 250.

Answer: D

Step-by-step explanation: D because if your turn 1/2 into a decimal point it 0.5 (don't forgot to add the negative) and so i then divided -0.5 from x and just got x then you have to do the same for the other side. So i took 4 and divided it by -0.5 and got -8 to the expression would be x is greater then or equal to -8. you plot the dot at -8 and the line goes in front of it because it is lesser or equal to x (remember you reverse the problem if you say it back words so don't get confused), but after my long explanation just pick D

Variability in statistics is the degree to which data in a set varies, or how much difference there is in a single set of data. The variability definition also refers to the consistency of the pattern in a set of data.

There are many measures of variability to help researchers determine how much variability is contained within a set of data. A simple measure of variability is the range, the difference between the highest and lowest scores in a set.

A concern when using a simple range measure is the existence of outliers, individual scores that are not grouped with the rest of the scores.

Current statistical studies are modern and have a wealth of analysis tools and software to understand the data. Statistics has a wide range of objectives, which aim not only to understand the variability of the data, but also its origin and motivation. For example, if an election poll shows a variation from a previous poll, statisticians will seek to understand the causes of these variability and not just present the variation in the data.

5x=150

x=150/5

x=30

Answer:

The value of x=17.

Step-by-step explanation:

3(x-1) = 4(x-5)

=3x-3=4x-20

Subtract both sides by 4x.

=3x-3-4x=4x-20-4x

= −x−3=−20

Add 3 to both sides.

=−x−3+3=−20+3

−x=−17

Divide both sides by -1.

−x/-1=−17/-1

Option C. 3/4.

the slope is 3/4 for any two adjacent points.

Then use the point-slope formula y-y1=m(x-x1) where m slope and (x1, y1) point

y-1=(3/4)(x-11)

y=(3/4)x-(29/4), distributing and moving the 1 over.

A linear function is a function of the form f(x) = ax + b, where a and b are real numbers. Here, a represents the gradient of the line, and b represents the y-axis intercept (which is sometimes called the vertical intercept).

3 number of roots exist for the polynomial function.

Step-by-step explanation:

As we know that the polynomial can only have exact number of roots as high as the degree of that polynomial is.

We can also prove it. Assume there is a polynomial

(x+2)(x+3) =0

Here the degree of the polynomial is 2 and the number of possible solutions are also 2. As it is evident that x is either equal to -2 or -3.

From the given condition,

(9x + 7)(4x + 1)(3x + 4)

we know that the degree of the polynomial is 3 because after expansion it becomes,

108x^3 + 255 x^2 +169x + 28 =0

Since, highest power of the variable is 3. Its degree is 3.

Therefore, possible number of roots that exist for the polynomial function are 3.

Answer:

Price of each ticket = $70

The revenue generated from sales of 10 tickets = 70 x 10 = $700

After selling the 10 tickets, organization was still at loss of $800. This means total product cost of tickets = $800 + $700 = $ 1500

Net Profit = Revenue - Cost

Revenue from n tickets will be = 70n

Cost = $1500

So, net profit as a function of number of tickets sold = P(n) = 70n - 1500

While dealing with laws of exponents, exponents should be subtracted when splitting exponential formulas with the same base.

Use the Quotient of Powers Rule to reduce the number of terms when splitting like terms with exponents. According to this rule, to determine the solution while dividing terms with the same base, simply remove their exponents. The trick is to only take out exponents with matching bases.

Exponents are added when two powers of the same base are multiplied. Therefore, the exponents are subtracted when two powers of the same base are divided. To put it another way, abac=ab + c is true for all real numbers a, b, and c.

It is so established that any integer or phrase raised to the power of zero always equals 1. To put it another way, the outcome is 1 if the exponent is 0. A 0 = 1 and (a/b) 0 = 1 create the general version of the zero exponent rule.

Answer in interval notation is (3, 5.94].

Step-by-step explanation:

First find the time that the ball is level with the top of the building on its descent. You can do this by solving 280 = -16^2 + 48t + 280 for t. This gives t = 3 seconds .

Then when the ball reaches the ground the time t is obtained by solving 0 = -16t^2 + 48t + 280 This gives t = 5.94

seconds.

Answer in interval notation is (3, 5.94].

The resulting point's coordinates, G', are rotated 90° clockwise around in the origin are (-1 , -1 ).

A coordinate plane is a two-dimensional plane created by the intersection of the y-axis, a vertical line, and the x-axis, a horizontal line. These really are perpendicular lines that cross at zero, which is known as the origin.

Quadrant one (QI) is the upper right fourth of a coordinate plane, where all coordinates are positive. Quadrant two (QII) is the coordinate plane's upper left fourth. Quadrant three (QIII) is the fourth from the bottom left. Quadrant four (QIV) is the fourth from the bottom right.

Point G(1,1)

X= 1 ,Y = 1

We can see that the point lies in the first quadrant because the value of X and Y are the positive.

the coordinates of the resulting point, G'  is rotated 90° clockwise around the origin.

As we know that the quadrant plane is divided into 4 part but if the point G rotates at 90 clockwise the the point will shift to the 4 quadrant and in the 4 quadrant the value of X and Y change And it became negative.

So

The resulting point's coordinates, G', are rotated 90° clockwise around in the origin are (-1 , -1 ).
