Sylvia is considering investing in one of two bond packages offered to her by different brokers. Broker U suggests that Sylvia buy two par value $1,000 bonds from Franklin County, three par value $500 bonds from Enam Telecom, and two par value $1,000 bonds from the city of Iligs. Franklin County bonds are selling at 96. 674, Enam Telecom bonds are selling at 109. 330, and Iligs bonds are selling at 103. 851. Broker V suggests that Sylvia buy four par value $500 bonds from Trochel Office Supplies, one par value $500 bond from Okaloosa county, and three par value $1,000 bonds from Globin Publishing. Bonds from Trochel Office Supplies are selling at 105. 142, Okaloosa county bonds are selling at 85. 990, and Globin Publishing bonds are selling at 97. 63. If Broker U charges a commission of 2. 8% of the market value of the bonds sold and Broker V charges a fee of $65 for each bond sold, which bond package will cost Sylvia less, and by how much? a. Broker V’s bond package will cost Sylvia $366. 00 less than Broker U’s. B. Broker V’s bond package will cost Sylvia $205. 77 less than Broker U’s. C. Broker U’s bond package will cost Sylvia $156. 02 less than Broker V’s. D. Broker U’s bond package will cost Sylvia $361. 79 less than Broker V’s.
The bond package that will cost Sylvia less will be C. broker U's package costs $156.02 less money than broker V's package.
How to calculate the bond packageBroker U: 2.8% commission
2 par value bonds $1,000 x 96.674% = $1,933.48
3 par value bond $500 x 109.330% = $1,639.95
2 par value bonds $1,000 x 103.851% = $2,077.02
Silvia's total investment:
= ($1,933.48 + $1,639.95 + $2,077.02) x 1.028
= $5,808.66
Broker V: $65 per bond plus
4 par value bonds $500 x 105.142% = $2,102.84
1 par value bond $500 x 85.990% = $429.95
3 par value bonds $1,000 x 97.063% = $2,911.89
Silvia's total investment will be:
= $2,102.84 + $429.95 + $2,911.89 + (8 x $65)
= $5,964.68
Broker V's offer - broker U's offer:
= $5,964.68 - $5,808.66
= $156.02

The MPC's and MPS's
The tax multipliers is calculated using
Tax multiplier = -MPC / (1 - MPC) or
Tax multiplier = - (1 - MPS) / MPS
Using the above as a guide, we have the following:
MPC = 0.90
Tax multiplier = -0.90/(1 - 0.90)
Tax multiplier = -9
MPS = 0.20
Tax multiplier = -(1 - 0.20)/0.20
Tax multiplier = -4
MPC = 0.75
Tax multiplier = -0.75/(1 - 0.75)

let 'm' be mid value of class and 'L' be upper limit in frequency table. The lower limit of class is ? Please prove and answer
Answer:
Lower Limit = 2m-L
Step-by-step explanation:
Given that,
The mid value of class = m
Upper limit in the frequency table = L
We need to find the lower limit of the class.
The mid value of a class is given by :
\(\text{mid-value}=\dfrac{\text{lower limit + upper limit}}{2}\\\\m=\dfrac{L+\text{lower limit}}{2}\\\\2m=L+\text{lower limit}\\\\\text{lower limit}=2m-L\)
Hence, the lower limit of the class is 2m-L.
two cars start moving from the same point. one travels south at 64 mi/h and the other travels west at 48 mi/h. at what rate is the distance between the cars increasing four hours later?
One car travel South at 64 mi/h and the other travels west at 48 mi/h. The distance between the cars increases with rate at 80 mi/h.
To find the rate of change, we need to find the derivative of the variables with respect to time.
Let:
p = distance between 2 cars
q = distance between car 1 and the start point
r = distance between car 2 and the start point
Using the Pythagorean Theorem:
p² = q² + r²
Take the derivative with respect to time:
2p dp/dt = 2q dq/dt + 2r dr/dt
dq/dt = speed of car 1 = 64 mi/h
dr/dt = speed of car 2 = 48 mi/h
The distance of car 1 and car 2 from the start point after 4 hours:
q = 64 x 4 = 256 miles
r = 48 x 4 = 192 miles
Using the Pythagorean theorem:
p² =256² + 192²
p = 320 miles
Hence,
2p dp/dt = 2q dq/dt + 2r dr/dt
p dp/dt = q dq/dt + r dr/dt
320 x dp/dt = 256 x 64 + 192 x 48
dp/dt = 80
Hence, the distance between the cars increases with rate at 80 mi/h

Bill rented a truck for one day. There was a base fee of $16.95 , and there was an additional charge of 83 cents for each mile driven. Bill had to pay $248.52 when he returned the truck. For how many miles did he drive the truck?
Answer:
279 miles
Step-by-step explanation:
First, subtract the base fee from his total charge:
248.52 - 16.95
= 231.57
Divide this by 0.83 to find how many miles he drove:
231.57/0.83
= 279
So, he drove 279 miles

When using the simple exponential smoothing forecasting method, which of the following is the major reason to use a = 0.1 rather than a = 0.5?
The major reason to use a value of 0.1 rather than 0.5 in the simple exponential smoothing forecasting method is to place more emphasis on recent data points.
In simple exponential smoothing, the forecasted value for the next period is calculated by combining the actual value from the current period with a weighted average of the forecasted value from the previous period. The weighting factor, represented by 'a', determines the level of importance given to the most recent data points.
By choosing a smaller value of 'a' (e.g., 0.1), more weight is placed on recent observations, resulting in a forecast that is more responsive to recent changes in the data. This is particularly useful when the underlying pattern in the data is changing rapidly or when there is a need to capture short-term fluctuations or trends.
On the other hand, choosing a larger value of 'a' (e.g., 0.5) would give equal weight to all data points, making the forecast more stable and less sensitive to recent changes. This is appropriate when the underlying pattern is relatively stable and there is a desire to smooth out short-term fluctuations in the data.

When do scientists use math in an experiment? How do you know?
Scientists use math in experiments when they make measurements, analyze quantitative data, and make predictions based on this data.
This is known because Math is an integral part of Science which is why both subjects ( Science and Math ) are considered STEM subjects.
How do scientists use math ?Scientists use math in an experiment to make measurements, analyze data, and make predictions.
For example, scientists use math to make precise measurements of physical quantities such as length, weight, and temperature. They also use math to perform calculations such as determining the concentration of a substance in a solution or the rate of a chemical reaction.
Scientists also use mathematical models and statistical analysis to analyze data and make predictions about the outcome of an experiment. They use mathematical equations to describe the relationships between different variables and to test hypotheses. They also use statistical techniques to determine the significance of their results and to make inferences about a larger population from a smaller sample of data.

Sam has worn a green shirt o 10 of the last 20 days. Considering this data,how many times would you expect sam to wear a green shirt in the next 12 days?
PLEASE GIVE AN EXPLANATION STEP BY STEP
THANKS
Answer: 6
Step-by-step explanation:
So, he wears the shirt 10 out of 20 days.
10 days is half of 20 days.
This means he wears the shirt approximately half of the time, by the logic of 10/20 days.
So, now we apply this to 12 days.
What's half of 12? 6.
This means that he most likely wears the green shirt on 6 out of the 12 days.
