the circle's area is approximately 2173.22 mm².We can find the radius of the circle by dividing the diameter by 2
what is diameter ?
Diameter is a straight line passing through the center of a circle or sphere and connecting two points on the circumference. It is the longest chord of the circle.
In the given question,
The diameter of a circle is 52.6 millimeters.
We can find the radius of the circle by dividing the diameter by 2:
radius = diameter/2 = 52.6/2 = 26.3 mm
Now, we can use the formula for the area of a circle:
area = π × radius²
Plugging in the values we have:
area = 3.14 × 26.3² = 3.14 × 691.69 ≈ 2173.21 mm²
Rounding to the nearest hundredth, we get:
area ≈ 2173.21 ≈ 2173.22 mm²

If the federal reserve decreases the reserve rate from 5% to 4%, how does this affect the money supply from a $50,000 deposit after fractional-reserve banking has multiplied it?.
If reserve rate decreases from 5% to 4% then money supply of $50000
deposits increases .i.e bank can save $2000 and can lend $48000.
The reserve ratio is the percentage of reserves (or cash deposits) that a bank must keep and not lend out. The higher the reserve requirement, the less money a bank can potentially lend—but this extra cash also prevents a bank from failing and strengthens its balance sheet. Still, when the reserve ratio rises, monetary policy is considered contractionary, and when it falls, monetary policy is considered expansionary.
Given this, the reserve rate falls from 5% to 4%.
$50000 is the initial deposit.
If the reserve ratio is 5%, the bank must keep 50000*0.05 = $2500 in reserve and may make loans totaling 50000-2500=$47500.
If the reserve ratio is reduced to 4%, a bank with $50000 in deposits must save 50000*0.04 = $2000 before it can lend $48000.
Thus, if reserve ratio decreases then the money supply increases.

Step-by-step explanation:
You want the solution and some observations about it for the system of equations ...
y = 2x +1y = -x +7a) Solution
The graph shows the lines cross at the point (x, y) = (2, 5).
The solution to the equations is (x, y) = (2, 5).
b) Values of yi) For x=2, the value of y in the first equation is ...
y = 2(2) +1 = 4 +1 = 5
For x=2, the value of y in the second equation is ...
y = -(2) +7 = -2 +7 = 5
ii) The values of y are the same, and match the value we found in part (a).

Additional comment
The purpose of the exercise is to get you to see that the value of x that is the solution makes both equations have the same value of y, and that is the value of y that is the solution.
The graph is a plot of the y-value for each x-value. Where the lines cross, the y-values are the same for that x-value. That point of intersection of the lines is the solution to the system of equations: the values of x and y satisfy both equations at that point.

The amount owed is $10865, based on the given parameters
How to determine the amount owed in six years?The given parameters about the compound interest are
Principal Amount, P = $5300
Interest Rate, R = 8%
Time, t = 6 years
To calculate the amount owed, we make use of the following formula
A = P + CI
Where
Compound interest, CI = P(1 + R)^t - P
So, the equation becomes
A = P + P(1 + R)^t - P
Evaluate the like terms
A = P(1 + R)^t
In this question, the formula is given as
A = P(1 + r/n)^nt
Where
n = 12, i.e compounded monthly
Substitute the known values in the above equation
A = 5300 * (1 + 8%/12)^(6*12)
Express 8% as decimal
A = 5300 * (1 + 0.08/12)^(6*12)
Evaluate the sum
A = 5300 * (1.01)^(6*12)
Evaluate the exponent
A = 5300 * 2.05
Evaluate the product
A = 10865
Hence, the value of the amount after 6 years is $10865

y equals 2 thirds times x plus 7
y equals negative 2 thirds times x plus 7
y equals 1 third times x plus 7
y equals negative 1 third times x plus 7
Answer:
[tex]\textsf{D)} \quad y =-\dfrac{1}{3}x+7[/tex]
Step-by-step explanation:
The line of best fit of a scatter plot is a straight line that represents the general trend or pattern. It should pass as close as possible to the majority of the data points, minimizing the overall distance between the line and the points.
From observation of the given scatter plot, the line shows a negative association. Therefore, the slope of the line is negative. This means we can immediately discount the equations with positive slopes.
If we plot the line with the slope -2/3 (attachment 1 - blue line), we can see that the line passes through the first point, then has 3 points above the line but only 1 point below it. The distance between point (6, 7) and the line is much greater than the distance between the line and the other points.
If we plot the line with the slope -1/3 (attachment 2 - red line), we can see that the line passes as close as possible to the majority of the data points, and minimizes the overall distance between the line and the points.
Therefore, the equation that is the best model for the line of best fit for the data is:

In order to solve for the variable in the equation
We want to apply the distributive property to the given expression.
1 - x - 2 + 2x = 10x - 25 - x is the result of this step.
Let's see how to solve this:
Remember that the distributive property says that:
A*(B + C) = A*B + A*C.
Here we have the expression:
1 - (x + 2) + 2x = 5*(2x - 5) - x
We can apply the distributive property to the first term in the right side, we will get:
1 - (x + 2) + 2x = 5*(2x - 5) - x
1 - (x + 2) + 2x = 5*2x - 5*5 - x
1 - (x + 2) + 2x = 10x - 25 - x
Now we can also apply the distribute property to the second term in the left side:
1 - (x + 2) + 2x = 10x - 25 - x
1 - x - 2 + 2x = 10x - 25 - x

It is proved that every non-empty finite set has the same number of subsets of even size as it has subsets of odd size
The set's members are numbered 1, 2, 3, 4,..., n.
There is a set with an odd number of items that corresponds to every subset with an even number of elements in the following manner:
Delete 1 from the set to create one with an odd number of elements if it is a member of the set with an even number of elements.
Add 1 to the set to create a set with an odd number of items if it isn't already a member of the set with an even number of elements.
Let's say the set has the numbers 1, 2, 3, and 4. The relationship between sets with even numbers of elements and sets with odd numbers of elements is as follows:

Betty finishes and leaves the bank. Carol goes to the available teller. What's the probability Alice leaves before carol?
The probability that Alice leaves before Carol is 0.5 according to the given information.
What is meant by probability?Probability is a branch of mathematics that deals with numerical descriptions of how likely an event or statement is to occur.
If X1 and X2 are both exponential distributions with parameters 1 and 2, respectively, then
P(X₁< X₂)= λ₁/(λ₁+λ₂ )
And P(X>s+t/x>s)=P(X>t), if X≈exp(μ)
Here, Let [tex]X_{A}[/tex], [tex]X_{C}[/tex] denote the service times for Alice and Carol
And also given that,
E[ [tex]X_{A}[/tex]]=1/μ
E[ [tex]X_{A}[/tex]]=4
E[ [tex]X_{C}[/tex]]=4
E[ [tex]X_{A}[/tex]]=E[ [tex]X_{C}[/tex]]=4
So, [tex]X_{A}[/tex], [tex]X_{C}[/tex] ≈exp(1/4)
Now, when Betty completes his service, Alice is still being served, and the remaining time required to complete his service is exp(1/4).
Because the exponential distribution has no memory.
So, P( [tex]X_{A}[/tex]< [tex]X_{C}[/tex] )= λ₁/ λ₁+ λ₂

The equation is written and interpreted as y is directly to x. At option 3,
y = kx
when y = 6 and x = 4, we would have 6 = 4k.
then k = 6/4
= 1.5
To confirm, we have to put the input values to see if they correspond with their y values.
1.5 x 6 = 9
1.5 x 8 = 12
Hence option 3.

what is the correct setup to finding the slope of a line that passes through the points (6,-3),(-2,7)
Answer:
slope = - [tex]\frac{5}{4}[/tex]
Step-by-step explanation:
calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (6, - 3 ) and (x₂, y₂ ) = (- 2, 7 )
m = [tex]\frac{7-(-3)}{-2-6}[/tex] = [tex]\frac{7+3}{-8}[/tex] = [tex]\frac{10}{-8}[/tex] = - [tex]\frac{5}{4}[/tex]
The slope of a line that passes through the points (6,-3),(-2,7) is -5/4.
What is a slope?In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction.
If a line passes through two points (x₁ ,y₁) and (x₂, y₂) ,
then the equation of line is
y - y₁ = (y₂- y₁) / (x₂ - x₁) x (x - x₁)
To find the slope of a line that passes through the points (6,-3),(-2,7):
To find the slope;
m = (y₂- y₁) / (x₂ - x₁)
m = (7+3)/(-2-6)
m = -10/8
m = -5/4
Therefore, the slope is -5/4.

Divide:
Repetitive subtraction is the process of division. It is the multiplication operation's opposite. It is described as the process of creating equitable groups. When dividing numbers, we divide a larger number down into smaller ones such that the larger number obtained will be equal to the multiplication of the smaller numbers. One of the four fundamental mathematical operations, along with addition, subtraction, and multiplication, is division. Division is the process of dividing a larger group into smaller groups so that each group contains an equal number of things. It is a mathematical operation used for equal distribution and equal grouping.
