The central angle is approximately 51.6 degrees.
How to find the Arc length of a central angle?To solve this problem, we can use the formula for arc length of a circle:
arc length = θ × r
where θ is the central angle in radians, and r is the radius of the circle.
We know that the arc length is 4.5 feet and the radius is 5 feet. So we can rearrange the formula to solve for θ:
θ = arc length / r
θ = 4.5 / 5
θ = 0.9 radians
To find the central angle in degrees, we can convert radians to degrees by multiplying by 180/π:
θ = 0.9 × (180/π)
θ ≈ 51.6 degrees
Therefore, the central angle is approximately 51.6 degrees.

A farmer goes to the market to sell a box of eggs. A clumsy horse steps on the box of eggs and breaks a lot of them. The horse’s rider offers to pay for all of the eggs in the box and asks the farmer how many eggs there were. The farmer does not remember the exact number, but when she took them out of the box two at a time, there was 1 egg left. The same thing happened when she took them out three, four, five and six eggs at a time, but when she took them out 7 at a time, there were no eggs left
The smallest number of eggs that could have been in the box is 1134
The problem is to find the smallest number of eggs that could have been in the box, given the remainder when taking them out by different numbers. Here are the moves toward tackling it:
Allow n to be the quantity of eggs in the container. Then we have the accompanying arrangement of congruences:
n ≡ 1 (mod 2)
n ≡ 1 (mod 3)
n ≡ 1 (mod 4)
n ≡ 1 (mod 5)
n ≡ 1 (mod 6)
n ≡ 0 (mod 7)
For this problem, we have k = 6 k = 6, a i = {1,1,1,1,1,0} a_i = {1,1,1,1,1,0}, M i = {1260,840,630,504,420,720} M_i = {1260,840,630,504,420,720}, and y i = {−1,−2,−3,-4,-5,-6} y_i = {-1,-2,-3,-4,-5,-6}.
Plugging these values into the formula and simplifying modulo 5040, we get:
n = (−1260 + −1680 + −1890 + −2016 + −2100 + 0) mod 5040
n = (−8946) mod 5040
n = (−3906) mod 5040
n = 1134 mod 5040
Therefore, the smallest number of eggs that could have been in the box is 1134

playing cards. what is the probability that the card will be a spade or a club? express your answer as a fraction or a decimal number rounded to four decimal places.
The probability of getting a spade, P(Spade), is 13/52 or 0.2500.
The probability of getting a club, P(Club) = 13/52 or 0.2500.
What is probability?Simply put, the probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of several outcomes. Statistics is the study of events that follow a probability distribution.
For instance, if you flip a coin 100 times, you have a 50% chance of getting heads, thus you should anticipate 50 heads. But when we actually test it, we may get 48 heads, 55 heads, or anything else at all, though it will typically be a figure close to 50.
We have a total of 52 cards in the deck.
So, the total number of outcomes = 52
Total number of spades cards = 13
Total number of clubs = 13
So, the sample space would be 13
The probability of getting a spade P(Spade) =13/52 = 0.2500
Similarly, The probability of getting a club P(Club) =13/52 = 0.2500

In order to get to work, Lindsay takes access roads that require a toll for drivers to use. She pays $4 each day to use the access roads. She also pays $5 each day to park her car at the company lot. Assuming the toll payments are used to plot the x-coordinate and the parking lot payments are used to plot the y-coordinate, which ordered pair represents how much money Lindsay spends during a 5-day work week?

C.
(

D.

)
The ordered pair that represents how much she spends on a 5-day week is (20,25)
The rates are given as:
\(Access\ Roads = \$4\)
\(Parking\ Lot= \$5\)
From the question, x represents the access to roads, and y represents the number of days she parked her car.
So, her daily expense is:
\(Daily = Access\ Roads \times x + Parking\ Lot \times y\)
This gives
\(Daily = 4\times x + 5\times y\)
\(Daily = 4x + 5y\)
For a 5-day work week, her daily expense is:
\(Daily = 4 \times 5 + 5 \times 5\)
\(Daily = 20 + 25\)
Express as ordered pair
\(Daily = (20 , 25)\)
Hence, the ordered pair that represents how much she spends is (20,25)

Eric walks around a triangular path. At each corner, he records the measure of the angle he creates. He makes one complete circuit around that path. What is the sum of three angle measures that he wrote down
Answer:
180 degrees
Step-by-step explanation:
What we simply want to do here is to find the sum of all the angles marked by Eric as he walks around the triangular path.
From the question, we are told that he walks around and made a complete circuit, marking a specific angle at each corner. So what this translates to is that at each corner, we have an angle, with the three angles marked forming a triangle.
And from preliminary trigonometry, we know that the sum of angles in a triangle is 180. So by adding each of the angles in the triangular part together, we have a total of 180 degrees

two six sided dice are rolled and the sum of the tow dice equals 7. what is the probability that one die is a 3
The probability that one die is a 3 is 0.167.
The concept of the conditional probability formula is one of the quintessential concepts in probability theory. The conditional probability formula gives the measure of the probability of an event, say B given that another event, say A has occurred.
The Bayes' theorem is used to determine the conditional probability of event A, given that event B has occurred, by knowing the conditional probability of event B, given that event A has occurred, also the individual probabilities of events A and B.
Note: In case P(B)=0, the conditional probability of P(A | B) is undefined. (the event B did not occur).
Number of ways to roll out two dice = 6 x 6 = 36
Let A be the event in which the sum of the two dice is 7.
∴ P(A) = 6/36
Let B be the event in which one die is 3.
∴ P(B) = 10/36
Let P(B∩A) be the event in which the sum of the dice is 7 and one die is 3.
P(B∩A) = 1/36
Applying the formula of conditional probability,
P (B|A) = P (A ∩ B)⁄P (A)
= 1/36 * 6/36 = 1/6 = 0.167
Thus, the probability that one die is a 3 is 0.167.

A bank has determined that the monthly balances of the checking accounts of its customers are normally distributed with an average balance of $1,200 and a standard deviation of $250. What is the probability that a randomly selected bank balance will be less than $1,000?
The probability that a randomly selected bank balance will be less than $1,000 is 0.2119, or approximately 21.2%.
To solve this problem, we need to use the normal distribution formula:
z = (x - μ) / σ
where:
x = the value we are interested in (in this case, $1,000)
μ = the mean (average) balance, which is $1,200
σ = the standard deviation, which is $250
z = the z-score, which tells us how many standard deviations the value is from the mean
First, we need to calculate the z-score:
z = (1,000 - 1,200) / 250
z = -0.8
Next, we need to find the probability of a z-score of -0.8 using a standard normal distribution table or calculator. The table or calculator tells us that the probability of a z-score of -0.8 is 0.2119.
Therefore, the probability that a randomly selected bank balance will be less than $1,000 is 0.2119, or approximately 21.2%.

The correct answer is: 3 premises and 1 conclusion.
A syllogism is a logical argument that consists of three parts: two premises and one conclusion. The premises are statements that provide evidence or reasons, while the conclusion is the logical outcome or deduction based on those premises. In a hypothetical syllogism, the premises and conclusion are based on hypothetical or conditional statements. By analyzing the premises and applying logical reasoning, we can determine the validity or soundness of the argument. It is important to note that the number of conclusions in a syllogism is always one, as it represents the final logical deduction drawn from the given premises.

Leon is 55 years old and plans to contribute $19,500 to his retirement account this year. About how much of this money should Leon allocate to stocks if he is using the Rule of 110?
Using the Rule of 110, Leon should allocate a portion of his $19,500 retirement contribution to stocks based on his age.
The Rule of 110 is a general guideline used to determine the percentage of an individual's investment portfolio that should be allocated to stocks based on their age. According to this rule, the percentage of stocks in the portfolio should be approximately equal to 110 minus the person's age.
In this case, Leon is 55 years old. Therefore, he should allocate approximately 55% (110 - 55) of his $19,500 contribution to stocks.
To calculate the amount Leon should allocate to stocks, we can multiply the contribution amount by the stock allocation percentage:
Stocks allocation = $19,500 x 0.55 = $10,725
Based on the Rule of 110, Leon should allocate approximately $10,725 to stocks for his retirement account this year.

Step-by-step explanation:
okay so first you make it so that the negative sign of the first part is on the outside because a negative base raised to an odd power equals a negative. next, you distribute the little 3 exponent outside of it, making it -8/27 x^6 y^3 for the left. next, distribute the exponent 2 outside of the parenthesis of the right part, making the whole thing -8/ 27 x^6 y^3 x 9/16 x^2 y^4. reduce the numerator 8 and denominator 16, making it -1/27 x^6 y^3 x 9/2 x^2 y^4, and afterward, reduce denominator 27 and numerator 9, making it -1/3 x^6 y^3 x 1/2 x^2 y^4. (to reduce, you just divide but GCF). then just calculate the product. -1/3 x 1/2=-1/6, x ^6 x x^2 is just x^6+2, which is x^8. finally, y^3 x y^4 is just y^3+4, which is y^7. therefore, the answer is -1/6 x^8 y^7
