The equation that will be used to determine the population, y, of Log Village x years after 2010 is y= 1800(1.09)ˣ
What is equation?
An equation is a mathematical statement which is made by two expressions connected by an equal sign. For example, 3x – 8 = 16 is an equation. Solving this equation, we get the value of the variable x as x = 8.
The population of Log Village is 1800 in 2010, and the population increases each year by 9%.
Initial population(p)= 1800
rate of increase(r)= 9%
Time(t)= x years.
The formula for the population after n years is p(1+r/100)ⁿ.
To determine the equation for the population after x years we have to put the values in the above expression.
So putting all the values we get,
The population, y, of Log Village x years after 2010 is
y= 1800( 1+9/100)ˣ
y= 1800(1.09)ˣ
Hence, The equation that will be used to determine the population, y, of Log Village x years after 2010 is y= 1800(1.09)ˣ

Sue and 4 friends share half a pizza. Each piece of pizza is the same size. Sue believes each piece of pizza has an angle measure of 30º. Is Sue correct? Explain.
Sue statement that each piece of pizza has an angle measure of 30º is incorrect
Stating if Sue's statement is correctAssuming the pizza is circular, we know that the total angle measure of a circle is 360 degrees.
If we cut the pizza into halves, we have two equal pieces, each with an angle measure of 180 degrees.
If Sue and her 4 friends share half a pizza, they are sharing one of these equal pieces.
If we divide the 180 degree angle of the piece of pizza by 5 (Sue and her 4 friends plus Sue herself), we get an angle measure of 36 degrees, which is what Sue believes.

Shipping terms were FOB shipping point. ACME prepaid the $91 freight. Terms were 5/10 EOM. When Century received the goods, 3 sets were defective. Century returned these sets to ACME. On April 08, Century sent a $275 partial payment. Century will pay the balance on May 06. What is Century’s final payment on May 06? Assume no taxes
Century's final payment will be on May 06 is $4,028.
Total cost of televisions:
51 TVs at $100 each = $5,100
8% discount = $100 x 8% x 10 = $80
5% discount = $100 x 5% x 10 = $50
5% discount = $100 x 5% x 31 = $155
Total discount = $80 + $50 + $155 = $285
Cost after discount = $5,100 - $285 = $4,815
Shipping cost: no additional cost
Returned sets:
3 *$100 = $300
ACME will issue a credit to Century for $300
Total cost:
$4,815 + $0 - $300 = $4,515

The highest point of a normal curve occurs at Group of answer choices the mean. two standard deviations to the right of the mean. approximately three standard deviations to the right of the mean. one standard deviation to the right of the mean.
The highest point of a normal curve, also known as a Gaussian distribution or bell curve, always occurs at the mean. This is because the normal curve is symmetrical around the mean, with the same number of values on either side of the mean. Therefore, the peak of the curve must be directly above the mean.
The standard deviation is a measure of how spread out the values in a distribution are. For a normal distribution, approximately 68% of the values fall within one standard deviation of the mean, 95% fall within two standard deviations of the mean, and 99.7% fall within three standard deviations of the mean. Therefore, while the highest point of the normal curve occurs at the mean, the curve does extend out to both sides of the mean, with the height of the curve gradually decreasing as the distance from the mean increases.
Specifically, the point at which the curve begins to flatten out on either side of the peak is approximately one standard deviation away from the mean. At two standard deviations away from the mean, the curve has flattened out significantly, and at three standard deviations away from the mean, the curve is almost entirely flat. This is known as the empirical rule, or the 68-95-99.7 rule.
Understanding the normal curve and its characteristics is important in statistics and data analysis, as many real-world phenomena can be approximated using a normal distribution. By knowing the mean and standard deviation of a distribution, we can make predictions about the likelihood of various outcomes occurring.

Find two numbers having a difference of 16 such that the result of adding their sum and their product is a minimum
Answer:
-8.5 and 7.5
Step-by-step explanation:
Let's call the two numbers x and y. We know that their difference is 16, so we can write:
x - y = 16 or x = y + 16
We want to find the values of x and y that minimize the expression:
x + y + xy
Substituting x = y + 16, we get:
(y + 16) + y + (y + 16)y
Simplifying and expanding, we get:
y^2 + 17y + 16
To minimize this expression, we can take its derivative with respect to y and set it equal to 0:
d/dy (y^2 + 17y + 16) = 2y + 17 = 0
Solving for y, we get:
y = -8.5
Substituting y = -8.5 into x = y + 16, we get:
x = 7.5
Therefore, the two numbers with a difference of 16 such that the result of adding their sum and their product is a minimum are -8.5 and 7.5.

Is ΔABC ~ ΔDEF? Explain.
Answer:
ΔABC and ΔDEF are similar by (AA).
option (2)
Step-by-step explanation:
Here to test if the two triangles are similar based on the information given I will attempt to see if they are similar using
Angle-Angle (AA) Similarity Theorem: If two angles of one triangle are congruent to two angles of another triangle, then the two triangles are similar.
Δ = 180°
therefore using the givens:
m∠CAB = 18°
m∠ABC = 110°
m∠ACB = 180°-110°-18° = 52°
now for ΔDEF
because we know corresponding parts of similar triangles are proportional
∠DEF ≅ ∠CAB
and because m∠ACB = 52° and m∠FDE = 52°
∠FDE ≅ ∠ACB
Therefore by AA, we have proven that these two triangles ΔABC and ΔDEF are similar.
so option (2)

Describe Probability?Probability is a branch of mathematics that deals with the study of random events and the likelihood of their occurrence. It is used to quantify the uncertainty associated with a particular event or outcome. In simpler terms, probability is a measure of the likelihood that a certain event will occur, expressed as a number between 0 and 1, where 0 indicates that the event is impossible and 1 indicates that the event is certain.
There are different types of probability, including classical probability, empirical probability, and subjective probability. Classical probability is based on the assumption of equally likely outcomes, while empirical probability is based on actual observations or experiments. Subjective probability, on the other hand, is based on personal judgment or belief.
The probability of getting tails on any single flip of a fair coin is 1/2. Since we are flipping the coin three times, the probability of getting exactly two tails is given by the binomial probability formula:
P(exactly 2 tails) = (number of ways to get 2 tails out of 3) * (probability of getting tails)² * (probability of getting heads)¹
The number of ways to get 2 tails out of 3 is given by the binomial coefficient "3 choose 2", which is 3. So we have:
P(exactly 2 tails) = 3 * (1/2)² * (1/2)¹ = 3/8
This means that the probability of getting exactly 2 tails in one trial of flipping the coin 3 times is 3/8.
To predict the number of repetitions out of 200 that will result in exactly 2 tails, we can multiply the probability of getting exactly 2 tails in one trial by the total number of trials:
Number of repetitions with exactly 2 tails = P(exactly 2 tails) * total number of trials
Number of repetitions with exactly 2 tails = (3/8) * 200
Number of repetitions with exactly 2 tails = 75
Therefore, we can predict that out of 200 repetitions of the experiment, approximately 75 of them will result in exactly 2 of the 3 flips landing on tails.

The Results:
a) The measure of ∠BDC = 67°
b) The measure of arc DAC = 46°
How to measure angles?a) The measure of ∠BDC
Since DC ⊥ AB, ∠DCB is a right angle, which means it measures 90°. Also, given that m∠DCB = 23, we can use the fact that the angles in a triangle sum to 180° to find ∠DBC.
∠DBC + ∠DCB + ∠B = 180 (angles in a triangle sum to 180)
∠DBC + 90 + 23 = 180 (substituting values)
∠DBC = 180 - 90 - 23 = 67°.
Thus, the measure of ∠BDC = 67°
b) The measure of arc DAC:
Since AB = AC, it implies that ∠ABC = ∠ACB (angles opposite to equal sides of an isosceles triangle are equal). Therefore, ∠ACB is also 23°.
Now, since ∠ACB is an inscribed angle that intercepts the arc DAC, the measure of the arc DAC is twice the measure of ∠ACB.
Arc DAC = 2 × ∠ACB = 2 × 23 = 46°.
Therefore, the measure of arc DAC is 46°.

Claire spins two spinners, each divided into equal sections labeled 1-8.
What is the probability that Claire spins a sum of 8? State what strategy you will use to answer the question, explain your choice, and then find the answer.
The probability that Claire spinning an 8 is around 0.078, or 7.8%.
How to calculate the favorable outcomes?We may use the strategy of calculating favorable results over total outcomes to get the likelihood that Claire spins a sum of 8. We must specifically determine how many possibilities there are to reach a sum of 8 when spinning the two spinners and divide that number by the total number of possible outcomes.
To illustrate, we can use a table to display all of the possible results for spinning two spinners labeled 1-8, and then compute the sum of each outcome:
There are 64 possible outcomes (8 spinners 1 choice times 8 spinner 2 choices), and we can see that there are 5 methods to reach a sum of 8: (2,6), (3,5), (4,4), (5,3), and (6,2). As a result, the likelihood of getting an 8 is:
P(sum of 8) = number of favorable outcomes / total number of outcomes
= 5 / 64
= 0.078125
So the likelihood of Claire spinning an 8 is around 0.078, or 7.8%.

The volume of a cone is a third of the volume of a cylinder, hence:
V = πr²h/3.
For both cases, the height variable h has an exponent of one, hence:
If the height of a cone is halved, the volume of the cone is halved.If the height of a cylinder is tripled, the volume of the cylinder is tripled.If we had doubled the radius for example, the volume would be multiplied by 2² = 4, as the radius is squared.

What is the unit price for a piece of cheese if 1. 24 pounds costs $11. 25
The unit price for a piece of cheese is $0.11 per pound.
To find the unit price, we need to divide the total cost by the total weight. In this case, we have 1.24 pounds of cheese that costs $11.25.
So, we can set up a proportion
1.24 pounds / $11.25 = x pounds / $1
To solve for x, we can cross-multiply
1.24 pounds * $1 = $11.25 * x pounds
1.24 = $11.25 * x
x = 1.24 / $11.25

Answer:
A. 2
Step-by-step explanation:
Let's interpret the function.
First, let's look at the top section:
[tex]f(x)=x+2[/tex] if [tex]x < 1[/tex]
So, if the value of x is less than 1, to find f(x), we should add 2 to x.
Let's check if x is less than 1:
[tex]x=3\\x < 1\\3 < 1[/tex]
3 is not less than one, so to find f(x), we cannot add 2 to x.
The second part of the function is:
[tex]f(x)=x-1[/tex] if [tex]x\geq 1[/tex]
So, if the value of x is greater than or equal to 1, to find f(x), we should subtract 1 from x.
Let's check if x is greater than or equal to 1:
[tex]x=3\\x\geq 1=\\3\geq 1[/tex]
3 is greater than or equal to 1, so to find f(x), we should use x-1.
[tex]x-1=\\3-1=\\2[/tex]
Thus, f(3) = 2; the answer is A.
