Answer:
The cost of a manicure set in Nina's store is $12.30.
Step-by-step explanation:
To find the cost of the manicure set in Nina's store, you can use the following formula:
Selling price = Cost + Cost * Markup percentage
Substituting the given values into this formula, you get:
Selling price = $8.36 + $8.36 * 47%
To find the value of the markup percentage, you can convert 47% to a decimal by dividing it by 100: 47/100 = 0.47
Then you can use this value in the formula to find the selling price:
Selling price = $8.36 + $8.36 * 0.47

What is a function ?Each element of X receives precisely one element of Y when a function from one set to the other is used. The sets X and Y are collectively referred to as the function's domain and codomain, respectively.
The collection of all potential inputs for a function is its domain. Think of this box as the f(x) = 2x function. The domain is only the collection of natural numbers when the input values are x = 1,2,3,4,..., and the values that are returned are referred to as the range.
The collection of all a function's outputs is its range. Example: Let's have a look at the function f: A->B, where f(x) = 2x and A and B each represent a "collection of natural numbers." The domain in this instance is A, and the co-domain is B. The range then appears as the function's output.

the average number of wins for a team is 7.6 for the season with a standard deviation of 1.3. What is the probability that the team will win more the 9 games this season?
The probability that the team will win more than 9 games this season, given the average number of wins for the team, is 4 %
How to find the probability ?The Z-score formula is:
Z = (x - mean) / standard deviation
Where x is the number of wins we're interested in (9), mean is the average number of wins (7.6), and standard deviation is the standard deviation of the number of wins (1.3)
Z = (9 - 7.6) / 1.3
= 2.3 / 1.3
= 1.77
This means that 9 wins is 1.77 standard deviations above the mean. The result is the probability of a team winning more than 9 games this season, which is around 0.04 or 4% from the standard normal distribution table.

Answer:
7/8 = 87.5%
Step-by-step explanation:
You have only one of eight (1/8) evenly divided sections that is orange. The rest is not orange (1 - 1/8 = 7/8).
Therefore, spinning once will yield 7/8 odds of not landing on orange, or 0.875 or 87.5%.
The probability of not getting orange is 87.5%. The correct option is C.
What is probability?Probability is a number that indicates the likelihood of an event occurring. Probability is defined as the ratio of favourable outcomes to all outcomes.
Probability = Number of favourable outcomes / Number of samples
Given that a spinner with repeated colours numbered from 1 to 8 is shown. Sections 1 and 8 are purple. Sections 2 and 3 are yellow. Sections 4, 5, and 6 are blue. Section 7 is orange.
You only have one of eight (1/8) evenly divided orange sections.
The rest is not orange,
P = (1 - 1/8

The fourth term of an arithmetic sequence is 20. The common difference is -1/5 times the first term. Graph the sequence.
Answer:
To graph an arithmetic sequence, you can start by plotting the first few terms of the sequence on the coordinate plane. The x-axis represents the term number, and the y-axis represents the value of the term.
In this case, we are given that the fourth term is 20 and the common difference is -1/5 times the first term. Let's say the first term is x. Then, the second term is x - (1/5)x = 4/5x, the third term is 4/5x - (1/5)x = 3/5x, and the fourth term is 3/5x - (1/5)x = 2/5x.
Therefore, the first four terms of the sequence are x, 4/5x, 3/5x, and 2/5x. If we plot these terms on the coordinate plane, we get the following graph:
(0, x)
(1, 4/5x)
(2, 3/5x)
(3, 2/5x)
This graph represents the first four terms of the arithmetic sequence. To find the fifth term, we can use the formula for the nth term of an arithmetic sequence: a_n = a_1 + (n - 1)d, where a_1 is the first term, d is the common difference, and n is the term number.
For this sequence, the fifth term is x + (-1/5)x = 4/5x. To find the sixth term, we can use the same formula: a_6 = x + (-1/5)x = 3/5x.
By continuing this process, we can plot the rest of the terms of the arithmetic sequence on the coordinate plane.

Part D: If Lucky continues to grow at the rate of 9 pounds per month beyond the expected six months, how much will Lucky weigh by the time he is one year old?
The table is given below.
The graph is given below.
The linear model that represents lucky's current weight in pounds as a function of his age in months is
f(x) = 9x - 15.
Lucky's weight in one year is 93 pounds.
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
Lucky current age and weight = 2 months and 3 pounds.
The growth rate of lucky per month = 9 pounds.

The coordinates on the graph from the table are:
(2, 3), (3, 12), (4, 21), (5, 30), (6, 39), (7, 48), and (8, 57).
The graph of the table is given below.
Now,
The function for the weight of the lucky in x months.
f(x) = mx + c
m = 9
(2, 3) = (x, f(x))
So,
3 = 9 x 2 + c
c = 3 - 18
c = -15
So,
f(x) = 9x - 15
Where x is the number of months.
Now,
The weight of lucky in one year i.e 12 months.
This means,
x = 12 months
f(12) = 9 x 12 - 15 = 108 - 15 = 93
Thus,
The table is given above.

The Board of Education (DOE) claims that the average salary of substitute teachers in school
district in Nassau County, NY, is about $175 per day. A random sample of 6 school districts is
selected, and the daily salaries (in dollars) are collected into calculation with sample mean is $80
and sample standard deviation is 6.3. Calculate at α = .05 significance level whether the true
mean greater than $175.
Please explain step by step and as clear as possible
The null hypothesis is rejected.
The mean is not greater than $175.
What is the hypothesis?An assumption or concept is given as a hypothesis for the purpose of debating it and testing if it might be true.
Given:
Sample size (n) = 6
Sample mean ([tex]\bar x[/tex]) = $80
Sample standard deviation(s)=6.3
Significance level(α)=0.05
We have to test the claim that the true mean greater than $175.
The null and alternative hypotheses:
H₀ : μ = 175
H₁ : μ > 175
Here, Population Standard deviation is unknown and sample size is less than 30.
So we will use t- distribution.
Test Statistic t,
t = ([tex]\bar x[/tex] - μ) / {s/√n}
t = (80−175) / (6.3 /√6)
t = (80−175) / (6.3 / 2.45)
t = − 95 / 2.57196423
t = −36.937
degree of freedom (df) = n−1
= 6−1
= 5
p-value at t = −36.937, df = 5 and α = 0.05
Absolute value of −36.937 = 36.937
Notice that 36.937 does not show up in the table, but it does fall between the two values 31.821 and 63.657.
So, p-value = 1
Since, p-value > α
That means, we fail to reject the null hypothesis (H₀).
Therefore, the true mean is not greater than $175.

the inaugural attendance of an annual film festival is 20,000. The attendance y increases by 5% each year
1. about how many people will attend the festival in the fifth year?
Answer:
24,241 people
Step-by-step explanation:
To determine the attendance at the festival in the fifth year, we need to calculate the cumulative increase in attendance over five years.
1st year: 20,000
2nd year: 20,000 * 1.05 = 21,000 (5% increase from the first year)
3rd year: 21,000 * 1.05 = 22,050 (5% increase from the second year)
4th year: 22,050 * 1.05 = 23,127.50 (5% increase from the third year)
5th year: 23,127.50 * 1.05 = 24,241.38 (5% increase from the fourth year)
So, in the fifth year the festival will be attended by approximately 24,241 people.

The length of y in the triangle is 18.55 units.
How to find the side of a triangle?A triangle is a polygon with three sides. The sum of angles in a triangle is 180 degrees. The side y of the triangle can be found using sine law.
Therefore,
a / sin A = b / sin B = c / sin C
Applying the sine law,
y / sin 106 = 15 / sin 51
cross multiply
y sin 51° = 15 sin 106°
divide both sides by sin 51°
y sin 51° / sin 51° = 15 sin 106° / sin 51°
y = 15 sin 106° / sin 51°
Therefore,
y = 15 × 0.96126169593 / 0.77714596145
y = 14.4189254391 / 0.77714596145
