Michael has an average daily balance on his credit card of $327.50. His credit card charges 11.99% annual interest. What will his monthly finance charge be?
Answer:
First, we need to calculate Michael's daily interest rate:
0.1199 / 365 = 0.0003282
Then, we can calculate his daily finance charge:
327.50 x 0.0003282 = 0.1075
To find his monthly finance charge, we multiply his daily finance charge by the number of days in a month:
0.1075 x 30 = 3.225
So Michael's monthly finance charge will be $3.23 (rounded to the nearest cent).
The Karns Recreation Hall needs to build a ramp. The height of the ramp must be 2 feet. The ramp will start 6 feet from the door. To the nearest tenth of a foot, how long will the ramp be?
Using the Pythagorean's theorem we can see that the length of the ramp is 6.32ft
How long the ramp will be?We know that the ramp is a right triangle whose legs are 2 ft and 6 ft. Remember that by Pythagorean's theorem we know that the square of the hypotenuse is equal to the sum of the squares of the legs.
Then the length of the ramp L will be:
L² = (2ft)² + (6ft)²
L = √((2ft)² + (6ft)²)
L = 6.32ft

PLEASE HELP ME PLEASE LOOK AT THE PICTURE BELOW
Answer:
162 square units
Step-by-step explanation:
You want the surface area of the trapezoidal prism.
Base areaThe triangle at the top of each base is a right triangle with leg 3 units and hypotenuse 5 units. This tells you it is a 3-4-5 right triangle and the width of the prism is 4 units.
The area of each trapezoidal base is ...
A = 1/2(b1 +b2)h = 1/2(3 +6)(4) = 18 . . . . . square units
Lateral areaThe lateral area is the product of the height of the prism (7) and the perimeter of the base. The vertical edges of the base are 3 and 6, the horizontal edge is 4 (see above), and the slant edge is shown as 5. This means the perimeter is 3+6+4+5 = 18 units.
The lateral area of the prism is ...
LA = Ph = (18)(7) = 126 . . . . . square units
Total surface areaThe total surface area of the prism is the sum of the areas of the two bases and the lateral area:
2(18) +126 = 162 . . . . . . square units
The surface area of the composite solid is 162 square units.

5. (10 points) The fill volume of an automated filling machine used for filling cans of carbonated beverage is normally distributed with a mean of 367 ml and a standard deviation of 3 ml. If all cans less than 358 or greater than 373 ml are scrapped, what proportion of cans is scrapped? Solution:
The proportion of cans that are scrapped is approximately 0.0241.
We know that the fill volume of cans follows a normal distribution with a mean of 367 ml and a standard deviation of 3 ml. Let's define X as the fill volume of a single can. Then we can write:
X ~ N(367, 3)
We want to find the proportion of cans that are scrapped, i.e., the proportion of cans with a fill volume less than 358 ml or greater than 373 ml. Let's call this proportion p:
p = P(X < 358 or X > 373)
To solve this problem, we can use the standard normal distribution and the z-score formula:
z = (X - μ) / σ
where μ is the mean and σ is the standard deviation of the distribution. We can standardize the values 358 and 373 using this formula:
z1 = (358 - 367) / 3 = -3
z2 = (373 - 367) / 3 = 2
Now we can find the probabilities of the two events separately using the standard normal distribution table or a calculator:
P(X < 358) = P(z < -3) ≈ 0.0013
P(X > 373) = P(z > 2) ≈ 0.0228
The probability of either event happening is the sum of the probabilities:
P(X < 358 or X > 373) = P(X < 358) + P(X > 373) ≈ 0.0241

It can be concluded that there exists ‘insufficient evidence’ depicting that the ‘new mean GPA is more than 2.75’.
Therefore, X= 2.7532; T = 0.1203; P = 0.4524.
How to solveH0: ‘The mean class GPAs for a given course’ is equal to 2.75.
H1: ‘The mean class GPAs for a given course’ exceeds 2.75.
Our 'sample size' n = 50 and we calculate the ‘sample mean and sd’ with 'Excel', through its respective code ‘AVERAGE()’.
The resultant ‘sample mean’ xbar equals to 2.7532, while implementing the code ‘STDEV.S()’ gives us the ‘sample sd’ s being 0.188164.
The ‘hypothesized mean’ μ0 is again fixed at 2.75. Given that the ‘population sd is unknown’, we are obliged to perform a ‘t-test’ in order to receive our data.
Evaluating this test statistic provides us with-
T = (xbar-μ0)/(s/√n)
= (2.7532-2.75)/(0.188164/√50)
= 0.0032/0.0266
= 0.1203
Also, taking into account the 'degrees of freedom', which is (n-1), we figure out that it sums up to 49.
After conjuring a 'students t distribution', we get a P-value of 0.4524. Hereby, as the ‘P-value surpasses the significant level of 0.05’, the ‘null hypothesis fails to be dismissed’.
Consequently, it can be concluded that there exists ‘insufficient evidence’ depicting that the ‘new mean GPA is more than 2.75’.
Therefore, X= 2.7532; T = 0.1203; P = 0.4524.

Consider the probability that exactly 91
out of 153
registered voters will vote in the presidential election. Assume the probability that a given registered voter will vote in the presidential election is 59%
.
Step-by-step explanation:
We can use the binomial distribution to compute the probability that exactly 91 out of 153 registered voters will vote in the presidential election, assuming that the probability that any given registered voter will vote in the presidential election is 59%.
The probability mass function of the binomial distribution is:
P(X = k) = (n choose k) * p^k * (1 - p)^(n - k)
where:
- n is the number of trials (in this case, the number of registered voters)
- k is the number of successes (in this case, the number of registered voters who will vote in the election)
- p is the probability of success on any individual trial (in this case, the probability that a given registered voter will vote in the election)
Using this formula, we can calculate:
P(exactly 91 out of 153 voters will vote) = (153 choose 91) * 0.59^91 * (1 - 0.59)^(153 - 91)
= 0.037
Therefore, the probability that exactly 91 out of 153 registered voters will vote in the presidential election is approximately 0.037, or about 3.7%.

to find the probability of exactly 3

arrivals in one thousandth of a minute, what are the values of y, ×, and e that would be used in that formula?
The values we used in the Poisson probability formula are:
μ = λ = 0.4168
x = 3
e ≈ 2.718
What is Poisson probability?The Poisson probability distribution is a statistical distribution that models the probability of a certain number of events occurring in a fixed interval of time or space, given the average rate of occurrence of the events.
The Poisson distribution has a mean and variance of λ. Therefore, in this case, the mean and variance of the number of Internet traffic arrivals in one thousandth of a minute are equal to λ.
We can find the value of μ by dividing the total number of arrivals (7000) by the total time period (16,780):
μ[tex]= 7000/16,780 = 0.4168[/tex]
We can use μ as the value of λ in the Poisson distribution since they are equal.
To find the probability of exactly 3 arrivals in one thousandth of a minute, we use the Poisson probability formula:
P(x=3) = (e^(-λ) * λ^x) / x!
where x = 3.
Substituting the values we have:
[tex]P(x=3)[/tex][tex]= (e^(-0.4168) * 0.4168^3) / 3![/tex]
Using a calculator, we can evaluate e^(-0.4168) to be 0.6596, and simplify the denominator:
[tex]P(x=3) = (0.6596 * 0.0287) / 6[/tex]
[tex]P(x=3) ≈ 0.000305[/tex]

The equation of the transformed function is y = -f(x + 6)
Given data ,
Let the function be represented as f ( x )
Now , the value of f ( x ) is
f ( x ) = x
On simplifying , we get
Reflecting over the x-axis: To reflect a function over the x-axis, we multiply the function by -1. This changes the sign of the y-coordinate of each point on the graph of the function. So, the function after reflection over the x-axis would be y = -f(x).
Translating 6 units left: To translate a function 6 units to the left, we replace x with (x + 6). This shifts the graph of the function horizontally to the left by 6 units. So, the function after translation 6 units left would be y = -f(x + 6)

Curly’s Life Insurance Co. is trying to sell you an investment policy that will pay you and your heirs $25,000 per year forever. A representative for the company tells you the policy costs $500,000. At what discount rate would this be a fair deal?
Provide the formula through excel
Answer:
a discount rate of 5%
Step-by-step explanation:
The formula to calculate the present value of a perpetuity is:
PV = PMT / r
Where PV is the present value, PMT is the constant payment, and r is the discount rate.
In this case, the PMT is $25,000 and the PV is -$500,000 (negative because it represents a cash outflow). So we can rearrange the formula to solve for r:
r = PMT / PV
r = $25,000 / -$500,000
r = -0.05 or -5%
Therefore, at a discount rate of 5%, the policy would be a fair deal.
To calculate this in Excel, you can use the following formula in a cell:
=r(-25000/500000)
This will give you a result of -0.05, or -5%, which represents the fair discount rate.
Hope this helps!

The average child in elementary school brings home 13 pieces of paper to show their parents each week. Students at Little Kids Elementary School are in a program that is supposed to be more focused on digital work than paperwork. In one week, five students brought home to following number of papers: 14, 12, 18, 8, 11
Conduct the steps of hypothesis testing to determine whether there is a different amount of papers brought home by the kids at Little Kids Elementary School compared to normal.
The steps of "hypothesis-testing" for papers bought home are stating the Null and Alternate Hypothesis, find level-of-significance, collecting data, determining p-value, and making decision.
The "Hypothesis-Testing" is defined as a statistical method used to make inferences about a population based on a sample of data. It involves making a assumption about a population parameter (such as its mean or proportion) and then collecting data to test whether the hypothesis is likely to be true or false.
The steps of hypothesis testing are:
Step 1: State the "Null-Hypothesis"
The null hypothesis (H₀) is = average number of papers brought home by the kids at Little Kids Elementary School is the same as the average for the general population, which is 13.
⇒ H₀: µ = 13,
Step 2: State the alternative hypothesis
The "Alternative-Hypothesis" (Hₐ) is = average number of papers brought home by the kids at Little Kids Elementary School is different from 13.
⇒ Hₐ: µ ≠ 13,
Step 3: Determine the level of significance
Let "significance-level" be "α = 0.05". This means we accept a 5% chance of making a "Type I Error"
Step 4: Collect the data and calculate test-statistic
The sample mean of the number of papers brought home by the kids at Little Kids Elementary School is:
⇒ x' = (14 + 12 + 18 + 8 + 11)/5 = 12.6,
The sample standard deviation is:
⇒ s = √[((14-12.6)² + (12-12.6)² + (18-12.6)² + (8-12.6)² + (11-12.6)²)/4] ≈ 3.71
The "test-statistic" ⇒ t = (x' - µ)/(s/√n);
where n = sample size = (5),
⇒ t = (12.6 - 13)/(3.57/√5) = -0.25,
Step 5: Determine of "p-value",
The "degrees-of-freedom" = 4, ..because 5 - 1 = 4,
We know that "p-value" for t = -0.63 with 4 "degrees-of-freedom" is approximately 0.8103.
Step 6: Making decision and interpreting results
The p-value is 0.8103 which is greater than "significance-level" of (0.05),
So we fail to reject the null hypothesis. and say that there is not enough evidence to conclude that the average number of papers brought home by the kids at Little Kids Elementary School is different from the population mean of 13.
Therefore, we can say that the digital work program did not have a statistically significant effect on the amount of papers brought home by the students at Little Kids Elementary School.

Lily took a survey of 80 students on 7th grade and 150 students in 8th grade she found that 80% of the 7th graders like country music while only 60% of the 8th graders like it. Which statement is true
If Lily took a survey of 80 students of 7th grade and 150 students of 8th grade, then there are 64 "7th" grade students, and 90 "8th" grade students who like music.
First we find the the number of students who like music in "7th-grade".
Number of 7th grader students that are being surveyed = 80,
Percent of 7th graders who like country music = 80%,
So, Number of 7th graders who like country music are
⇒ 80% of 80 = 0.8 × 80 = 64
So, 64 out of the 80 students in 7th grade like country music.
For 8th graders;
Number of "8th-grader" students that are being surveyed = 150,
Percent of 8th graders who like country-music = 60%,
So, Number of 8th graders who like country music
⇒ 60% of 150 = 0.6 × 150 = 90,
Therefore, 90 out of the 150 students in 8th grade like country music.

2) Percent of time that customers at the new store bought milk shakes is:
26%
3) Percent of total sales that were ice cream is: 78%
4) Percent of new store sales of both shops is: 35%
How to find the percentage?We are given the following parameters:
Number of Servings of Icecream in Old store = 52100
Number of milk shakes in old store = 13400
Number of Servings of Icecream in New store = 25800
Number of milk shakes in new store = 9200
1) Percent of time that customers at the old store bought milk shakes is:
Percentage = [13400/(52100 + 13400)] * 100%
≈ 20%
2) Percent of time that customers at the new store bought milk shakes is:
Percentage = [9200/(25800 + 9200)] * 100%
≈ 26%
3) Percent of total sales that were ice cream:
Percentage = [(52100 + 25800)/(52100 + 25800 + 13400 + 9200)] * 100%
≈ 78%
4) Percent of new store sales of both shops is:
Percentage = (25800 + 9200)/(52100 + 25800 + 13400 + 9200)] * 100%
