A circle has a diameter of 3 m which statement about the circumference and area is true a comparison of the area and circumferen
Sveta_85 [38]

We conclude that the numerical value for the circumference is larger than the numerical value for the area.

<h3>What can we conclude about the area and the circumference?</h3>

Remember that for a circle of diameter d, the circumference is:

C = pi*d

And the area is:

A = pi*(d/2)^2

Where pi = 3.14

Here we know that d = 3m, replacing that in the above equations we get:

C = 3.14*3m = 9.42m\\\\A = 3.14*(3m/2)^2 = 7.065 m^2

While the units are different, we conclude that the numerical value for the circumference is larger than the numerical value for the area.

Find the solution of the system of equations<br> shown on the graph,<br> Enter the correct answer
MissTica

Answer: (0,4)

Explanation: What you're looking for is their point of intersection.

The point where the two lines intersect is the solution to the system.

In this case, the to lines intersect at the point (0,4).

So (0,4) is the solution to the system.

PLEASE HELP WILL GIVE BRAINLIEST IF CORRECT
rusak2 [61]

Answer:

To find the simple interest, we multiply 40000 × 0.12 × 10 to get that:

The interest is: $48000.00

Usually now, the interest is added onto the principal to figure some new amount after 10 year(s),

or 40000.00 + 48000.00 = 88000.00. For example:

If you borrowed the $40000.00, you would now owe $88000.00

If you loaned someone $40000.00, you would now be due $88000.00

Step-by-step explanation:

hope this helps!

g In American roulette, the wheel has the 38 numbers, 00, 0, 1, 2, ..., 34, 35, and 36, marked on equally spaced slots. If a pla
earnstyle [38]

Answer:

The expected value for the player to play one time is -$0.05.

Step-by-step explanation:

The expected value of a random variable <em>X</em> is given by the formula:

E(X)=\sum x\cdot P(X)

The American roulette wheel has the 38 numbers, {i = 00, 0, 1, 2, ..., 34, 35, and 36}, marked on equally spaced slots.

The probability that the ball stops on any of these 38 numbers is same, i.e.

P (X = i) = \frac{1}{38}.

It is provided that a a player bets $1 on a number.

If the player wins, the player keeps the dollar and receives an additional $35.

And if the player losses, the dollar is lost too.

So, the probability distribution is as follows:

<em>     X </em>: $35      -$1

P (<em>X</em>) :   \frac{1}{38}         \frac{37}{38}  

Compute the expected value of the game as follows:

E(X)=\sum x\cdot P(X)

         =[\$35\times \frac{1}{38}]+[-\$1\times \frac{37}{38}]\\\\=\frac{\$35-\$37}{38}\\\\=-\frac{\$2}{38}\\\\=-\frac{1}{19}\\\\=-0.052632\\\\\approx -\$0.05

Thus, the expected value for the player to play one time is -$0.05.

Here is a scale drawing of a window frame that uses a scale of 1 cm to 6 inches.Create another scale drawing of the window frame
Tresset [83]

Answer:

Step-by-step explanation:

Below is the rectangle in the attachment.

Current scale:

1 cm : 6 inches

If the dimensions of the rectangle is:

Length = a cm

Width = b cm

Using the scale:

Length = a × 6 inches

Width = b × 6 inches

Using the same dimensions of the rectangle is:

Length = a cm

Width = b cm

Using the scale:

Length = a × 12 inches

Width = b × 12 inches

Note that there is an enlargement of the rectangle to form the new rectangle. The length and width of new rectangle drawn will be 2 × the length and width of the rectangle seen below.
