Answer:

58.43%

Step-by-step explanation:

The first thing we must do is calculate the probability of when both are equal, that is, take out two cookies of the same type, since we can calculate that they are not equal by means of their complement:

The probability that they are equal is:

P (plain, plain) = (12/20) (11/19)

= 132/380

P (chocolate, chocolate) = (5/20) (4/19)

 = 20/380

P (currant, currant) = (3/20) (2/19)

= 6/380

The final probability would be the sum of these:

P (equal) = 132/380 + 20/380 + 6/380

P (equal) = 158/380

P (equal) = 0.4157

The probability that they are different is the opposite of the probability that they are equal, that is, the complement. Therefore, the probability that they are different is:

P (different) = 1 - 0.4157

P (different) = 0.5843

In other words, the probability would be 58.43%

Unit conversion is the conversion of one unit to another unit with its standard conversion.

The distance traveled in 15 minutes at a speed of 12m/s is 10800 m.

It is the conversion of one unit to another unit with its standard conversion.

Example:

1 minute = 60 seonds

1 km = 100 m

1 m = 100 cm

We have,

Speed = 12 m/s

This means,

1 second = 12 m

Now,

1 minute = 60 seconds

15 minutes = 15 x 60 seconds

15 minutes = 900 seconds

So,

1 sec = 12 m

Multiply 900 on both sides.

900 x 1 sec = 900 x 12m

900 seconds = 10800 m

Thus,

The distance traveled in 15 minutes at a speed of 12m/s is 10800 m.

Answer:

input = 6 leads to output = 15

input = 9 leads to output = 21

==================================================

Explanation:

If the input is x = 6, then,

y = 2x+3

y = 2(6)+3

y = 12+3

y = 15 is the output

Repeat those steps for x = 9

y = 2x+3

y = 2(9)+3

y = 18+3

y = 21 is the output

Answer:

The coordinates of the point X:

Step-by-step explanation:

Let X be the point.

As the point X is in the directed line segment from (-2,-8) to (5,-1) into the ratio of 1 to 6

i.e.

\(\left(x_1,\:y_1\right)\:=\:\left(-2,-8\right)\)

\(\left(x_2,\:y_2\right)=\left(5,-1\right)\)

Rise = y₂ - y₁

       \(= -1 - (-8)\)

       \(= -1 + 8\)

       \(= 7\)

Run = x₂ - x₁

      \(= 5 - (-2)\)

      \(= 5 + 2\)

      \(= 7\)

1 : 6 ratio means the point X lies at

\(\frac{1}{6+1}=\frac{1}{7}=14\%\)

Thus,

rise for X \(=\:7\:\times \:14\%=1\)

run for X \(=\:7\:\times \:14\%=1\)

Thus, coordinates of X will be:

\(x = -2 + 1 = -1\)

\(y = -8 + 1 = -7\)

Therefore, we conclude that:

The coordinates of the point X:

The point (-1, -7) divide the segment from (-2,-8) to (5,-1). in the ratio 1:6.

If a point O(x, y) divides the line segment AB in the ratio of n:m, where the endpoints of the line is A(x₁, y₁) and B(x₂. y₂), the point O is at:

\(x=\frac{n}{n+m}(x_2-x_1)+x_1 \\\\y=\frac{n}{n+m}(y_2-y_1)+y_1\)

Given the ratio 1:6, let O(x, y) divide the segment from (-2,-8) to (5,-1). Hence:

\(x=\frac{1}{1+6}(5-(-2))+(-2)=-1\\\\y=\frac{1}{1+6}(-1-(-8))+(-8)=-7\)

O = (-1, -7)

The point (-1, -7) divide the segment from (-2,-8) to (5,-1) in the ratio 1:6.

Answer:

6 gallons per minute

Step-by-step explanation:

Let the function that models the quantities of water, Q (in gallons) in a pool over time, t (in minutes), is  

Q = a + bt ........... (1)

Now, Q(t = 0) is given to be 50 gallons.

So, a = 50 and b denotes the rate at which the quantity of water in the pool is decreasing and it is given by the slope of equation (1).

Now, two points on the graph are (0,50) and (1,44).

So, the slope = b =  = - 6 gallons per minute.

Therefore, the equation of this situation is given by Q = 50 - 6t, where the slope is equal to - 6 gallons per minute. (Answer)

The slope of the line graph representing the data would be described as "negative" or "decreasing."

We have,

The slope of a line represents the rate of change between two variables.

In this case, the variables are "Time in minutes" and "Water in Pool in gallons.

" The slope of the line graph representing this data would be described as "negative" or "decreasing."

This is because as time increases (going from 0 to 5 minutes), the amount of water in the pool is decreasing (going from 50 gallons to 20 gallons).

When the slope of a line is negative, it indicates a decreasing trend or a decrease in the value of one variable as the other variable increases.

Thus,

The slope of the line graph representing the data would be described as "negative" or "decreasing."

Step-by-step explanation:

"An integer is the number 0 or any number obtained by repeatedly adding 1 to this number" is not entirely true.

True that integers can be represented by repeatedly adding or subtracting the number 1,

The fact that integers can also be negative and can be obtained by repeatedly subtracting 1 from 0 or another negative integer.

The definition does not account for the fact that integers can be represented using other operations, such as multiplication or division. The integer 12 can be represented as 4 x 3 or as 24 ÷ 2.

A more accurate definition of an integer is a whole number that can be positive, negative, or zero.

Integers can be represented using addition, subtraction, multiplication, or division, and can be used to represent quantities such as counts, distances, temperatures, and other measurable quantities.

The original definition is a useful way to understand how integers can be represented using addition and subtraction, it is not a complete or entirely accurate definition of what integers are.

Answer:

$1,015

Step-by-step explanation:

Given that:

Weekly earning = $625

Commission = 12% of sales

sales made last week = $3250

Last week earning = weekly earning + commision on sale

Commission on sale = 12% of sales

Commission on sale = (0.12 * 3250) = $390

Last week earning = weekly earning + commision on sale

Last week earning = $625 + $390 = $1,015

The minimum monthly payment to pay off a $5500 loan with a 5% interest rate for a term of 2 years is $247.49.

To calculate the minimum monthly payment to pay off a $5500 loan with a 5% interest rate for a term of 2 years, you can use the formula for calculating the monthly payment on a loan, which is:

P = (L[i(1 + i)ⁿ])/([(1 + i)ⁿ] - 1) where:

P = monthly payment

L = loan amount

i = interest rate per month

n = number of months in the loan term

Given:

L = $5500

i = 0.05/12 (5% annual interest rate divided by 12 months)

= 0.0041667

n = 2 years x 12 months/year

= 24 months

Plugging these values into the formula, we get:

P = ($5500[0.0041667(1 + 0.0041667)²⁴])/([(1 + 0.0041667)²⁴] - 1)

P = $247.49

Answer:

The yield of the stand if one-tenth of the trees are cut is 360000 board-feet.

Step-by-step explanation:

First, let is find the total amount of fir trees that occupies the area of 24 hectares. (1 hectare = 10000 square meters)

\(n = \sigma \cdot A\)

Where:

\(\sigma\) - Surface density, measured in trees per square meter.

\(A\) - Total area, measured in square meters.

Given that \(\sigma = \frac{1}{20}\,\frac{tree}{m^{2}}\) and \(A = 24\,h\), the total amount of fir trees is:

\(n = \left(\frac{1}{20}\,\frac{trees}{m^{2}} \right)\cdot (24\,h)\cdot \left(10000\,\frac{m^{2}}{h} \right)\)

\(n = 12000\,trees\)

It is known that one-tenth of the tress are cut, whose amount is:

\(n_{c} = 0.1 \cdot n\)

\(n_{c} = 0.1 \cdot (12000\,trees)\)

\(n_{c} = 1200\,trees\)

If each tree will yield 300 board-feet, then the yield related to the trees that are cut is:

\(y = S\cdot n_{c}\)

Where:

\(S\) - Yield of the tress, measured in board-feet per tree.

\(n_{c}\) - Amount of trees that will be cut, measured in trees.

If \(n_{c} = 1200\,trees\) and \(S = 300\,\frac{b-ft}{tree}\), then:

\(y = \left(300\,\frac{b-ft}{tree} \right)\cdot (1200\,trees)\)

\(y = 360000\,b-ft\)

The yield of the stand if one-tenth of the trees are cut is 360000 board-feet.
