There are twelve marbles in a bag (7 green, 4 yellow, and 1 blue). What is the probability that you pull a green marble (and keep it) and then pull another green marble?

The equation of the circle can be given by: (x - 8)² + (y - 5)² = 9.

The equation for a circle in standard form is (x - x1)² + (y - y1)² = r², where (x, y) denotes arbitrary coordinates on the circle's perimeter, r denotes the circle's radius, and (x1, y1) denotes the coordinates of the circle's center.

Now,

=> (x - 8)² + (y - 5)² = 9

Hence, the equation that describe the circle of radius 3 centered at (8, 5, 6) that is parallel to the xy-plane is given by: (x - 8)² + (y - 5)² = 9

The calculated mean age of Regina's brothers is 7. This is being attained by using the concept of measure of central tendency i.e. mean.

What is a mean?

Mean is interpreted as the total of all values divided by the total number of values. It is also called a mathematical average. There are three types of mean namely, arithmetic, geometric and harmonic mean.

Calculation of the mean age of Regina's brothers

Total number of Regina's brothers = 5

Sum of their ages = 4 + 6 + 6 + 9 + 10

= 35

Mean age = sum of their ages / total number

= 35 / 5

= 7

Hence, the calculated mean ages of Regina's brothers is 7

The age of Bashir is 15 years.

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

let the consecutive age be x, x+1, x+2 and x+3.

Now, sum of their ages is 66

So, x+ x+1 + x+2 + x+3 = 66

Simplifying for x, we get

4x+6=66

subtract 6 from both sides

4x=60

divide both sides by 4

4x /4 = 60/4

x= 15

Hence, Bashir age is 15 years.

The equation will be: 4.65r + 4.95p = 874.80

The total cost of gas will be sum of the individual costs of both the types of gas. Firstly, calculating cost of regular and premium gas followed by forming the equation.

The total cost of regular gas = Amount of regular gas × Cost of regular gas per gallon

The total cost of regular gas = 4.65 × r

The total cost of premium gas = Amount of premium gas × Cost of premium gas per gallon

The total cost of regular gas = 4.95 × p

We are given overall spending = 874.80

Forming the equation -

Total cost of regular gas + total cost of premium gas = overall spending on gas

4.65r + 4.95p = 874.80

Hence, the equation that models the situation is 4.65r + 4.95p = 874.80.

In a heptagon, the sum of all seven angles is 900 degrees. If you add up the four given angles you will get 600 degrees. In the question it says, "the remaining interior angles are EQUAL" so therefore, the only way to get from 600 to 900 from the remaining three angles is 100. Each remaining angle is 100 degrees

Answer:

Heptagons are known to have seven interior angles that add up to 900°, so we must find the last 3. First, add the first four they gave us.

[tex]160\circ + 130\circ = 290\circ\\= 290\circ + 170\circ + 140\circ\\170\circ + 140\circ = 310\circ\\= 290\circ + 310\circ\\= 600\circ[/tex]

We now know that the remaining angles are all 100°, because the question mentions the rest of the interior angles being equal. The only reasonable 3 equal numbers to add up to 900° would be three 100s in this case.

The correct symbols that complete the statements are

From the question, we are to determine the correct symbols that complete the given statements

The given statements are

h(0) ___ g(0)

and

To complete the statements, we will find the values of the given functions from the graph

From the graph of h(x), we can observe that

h(0) = 4

and

From the graph of g(x), we can observe that

g(0) = 4

Thus,

The two functions are equal

h(0) = g(0)

Also,

From the graph of h(x),

h(1) = 3

and

From the graph of g(x),

g(1) = 2

That is, h(1) is greater than g(1)

Using proportions, it is found that the cost of the 5 t-shirts would be of 564.83 Kronas.

A proportion is a fraction of a total amount, and equations can be built to find the desired measures in the problem using a rule of three, that can be either direct(cross multiplication) or inverse(line multiplication), deriving from proportional relationships. One example of application of proportions is for currency conversion problems, as multiplication or division operations are applied according to the rates of each coin.

For this problem, we have that 7 t-shirts cost $90.93, hence the cost of a t-shirt in U.S. dollars is given applying the proportion to find the unit rate as follows:

$90.93/7 = $12.99.

The cost of 5 t-shirts will be given by:

5 x 12.99 = $64.95.

Applying the proportion 1 U.S. Dollar = 8.6964 Krona, the cost in Kronas is:

64.95 x 8.6964 = 564.83 Kronas.

The cost of the 5 t-shirts would be of 564.83 Kronas.

Answer:

Step-by-step explanation:

If Katie invested a total of $8000, part at 5% simple interest and  part at 6% simple interest and at the end of one year the investments had earned $454 interest, then she invested $2600 at 5% and $5400 at 6% simple interest

Given,

The total invested amount = $8000

Consider the amount invested at 5% simple interest as x and the amount invested at 6% simple interest as y

Then, the equations will become

x + y= 8000

x = 8000-y

At the end of one year the investment = $454

0.05x + 0.06y =454

Substitute the value of x in the equation

0.05(8000-y) + 0.06y =454

400-0.05y+0.06y =454

0.01y+400=454

0.01y =54

y = 5400

Substitute the value of x in

x + y = 8000

x+5400=8000

x=8000-5400

x=2600

Hence, if Katie invested a total of $8000, part at 5% simple interest and  part at 6% simple interest and at the end of one year the investments had earned $454 interest, then she invested $2600 at 5% and $5400 at 6% simple interest
