A movie studio keeps 240 dresses in its wardrobe for historical films. Three-fifths of them can be used for movies that take place in the 1700s and 15% of them can be used for movies in the civil war era.
What percent of the dresses are for films set in the 1700s or during the civil war era? Explain how you found your answer
The percent of the dresses that are for films set in the 1700s or during the civil war era is; 75%
How to find the percentage?Percentage is normally calculated by dividing the value by the total value, and then multiplying the result by 100. It is given by the expression; Percentage = (value / total value) * 100%
Now, we are told that;
Number of movie dresses kept = 240 dresses
Fraction used for movies that take place in the 1700s = 3/5
Percentage used for movies in the civil war era = 15%
Thus;
Number of dresses in the 1700 = 3/5 * 240 = 144
Number of dresses for the civil era = 15% * 240 = 36
Thus;
Total for civil era and in the 1700s = 144 + 36 = 180
Thus;
Percentage for either period = 180/240 * 100% = 75%

8-2. Skills Practice. Multiplying a Polynomial by a Monomial.
To multiply a polynomial by a monomial, you must first identify the terms in the polynomial, as well as the factors in the monomial. Once you have identified the components, use the distributive property to multiply each term of the polynomial by the monomial. Then, combine like terms and simplify the resulting polynomial.
For example:
To multiply 3x2 + 2x - 5 by 2x, you would use the distributive property to multiply each term of the polynomial by the monomial: 3x2 * 2x = 6x3, 2x * 2x = 4x2, and -5 * 2x = -10x. The resulting polynomial is 6x3 + 4x2 - 10x.Learn more about Polynomial: https://brainly.com/question/24662212

How many palindromes greater than 10000 and less than 100000 are multiples of 18?
Let \(n=abcba\) be such a number. If 18 divides \(n\), then both 2 and 9 divide \(n\).
To be divisible by 2, we must have \(a\in\{2,4,6,8\}\). Meanwhile we can have \((b,c)\in\{0,1,2,\ldots,9\}^2\).
To be divisible by 9, we the sum of the digits of \(n\) must itself be divisible by 9, or
\(2a+2b+c=9k\)
for some integer \(k\).
The largest value of \(2a+2b+c\) is 2•8 + 2•9 + 9 = 43, so we must have \(k\in\{1,2,3,4\}\).
I'm not sure what the best way to get the final count may be, but there are 44 such numbers. It's rather tedious to do by hand.
• If \(k=1\), then \(2a+2b+c=9\), and we can do this in 4 ways.
For example,
2•2 + 2•0 + 5 = 9 \((n = 20502)\)
• If \(k=2\), then \(2a+2b+c=18\) and can be done in 16 ways.
2•2 + 2•3 + 8 = 18 \((n = 23832)\)
• If \(k=3\), then \(2a+2b+c=27\) and can be done in 18 ways.
2•2 + 2•7 + 9 = 27 \((n = 27972)\)
• If \(k=4\), then \(2a+2b+c=36\) and can be done in 6 ways.
2•6 + 2•8 + 8 = 36 \((n = 68886)\)

Is it possible to design a pair of nonstandard dice, with positive integers on the faces (not necessarily all distinct), so that the probability of rolling any given total on those two dice is the same as the probability of rolling that total on two standard dice
you can reduce it to factors of degree 2 or less).
The two dice do not need to be identical. If it is possible, do it. If it is not possible, prove that it is not possible.
Some hints I got were to try to construct a pair of nonstandard dice such that the generating function for their sum matches the corresponding g.f. for a pair of standard dice and to note that the g.f. for a pair of standard dice can be factored quite a bit (you can reduce it to factors of degree 2 or less).

A survey was conducted to investigate whether alcohol consumption and smoking are related. In a random
sample of 300 smokers, 196 said they had consumed alcohol at least once in the past week. In an
independent random sample of 300 non-smokers, 159 said they had consumed alcohol in the past week. If
P, is the proportion of smokers in the population who have had a drink in the past week and P is the
corresponding proportion of non-smokers, then a test of the hypotheses H, P, -P-0 against the two-sided alternative produces a test statistic of z=3.07 and a P-value of 0.002. If we had instead analyzed these results with a chi-square test of homogeneity, which of the following would be the test statistic and P-value?
a-942, P-value = 0.002
b. -942, P-value-0.004
-3.07, P-value - 0.004
d. -1.75, P-value = 0.002
e-1.75, P-value=0.004
e) The test statistic and P-value for the chi-square test of homogeneity would be -1.75 and 0.004, respectively.
A chi-square test of homogeneity is a useful tool for comparing two or more categorical variables. In this case, the two variables are smoking (smokers and non-smokers) and alcohol consumption (those who had consumed alcohol in the past week and those who hadn't).
The chi-square statistic is calculated by finding the difference between the observed and expected frequencies of the two groups and squaring it. The expected frequencies are found by multiplying the sample size by the overall probability of success (in this case, drinking alcohol).
The P-value is then calculated based on the chi-square statistic and the degrees of freedom (in this case, one). In this case, the chi-square statistic is -1.75 and the P-value is 0.004.

The relative density of steel is 7.8. Find: 1. the mass of a solid steel cube of side 10cm.
2. the volume of the steel that has a mass of 8kg
a) The mass of the solid steel is M = 7800 kg
b) The volume of the steel is V = 1.0256 cm³
Given data ,
The relative density of steel is 7.8
Now , Mass = Density x Volume
a)
The side length of the solid steel is s = 10 cm
So , the volume of solid is V = 10³ = 1000 cm³
The mass of the solid is M = 7.8 x 1000
M = 7800 kg
b)
The mass of steel is M = 8 kg
So, the volume of steel is V = M / D
V = 8 / 7.8
V = 1.0256 cm³

Part B: Solve the equation showing all work. (4 points)
Part C: Explain what the value of the variable represents. (2 points)
Answer:
Alex has 3x dollars and an extra 15 dollars in his coat pocket. He buys a new Nike shoe for 84 dollars. How much money did Alex spend that was not in his pocket.
Step-by-step explanation:
Answer:
Part A: Word problem
Maria went to the store and purchased some books for her book club. Each book cost $3, and she also bought some bookmarks at $15 each. Maria's total purchase, including tax, amounted to $84. If Maria bought x books, write an equation to represent the situation.
Part B: Solution
To solve the equation 3x + 15 = 84, we need to isolate the variable x on one side of the equation.
Step 1: Subtract 15 from both sides of the equation to eliminate the constant term on the left side:
3x + 15 - 15 = 84 - 15
3x = 69
Step 2: Divide both sides of the equation by 3 to isolate x:
3x/3 = 69/3
x = 23
So, the solution to the equation is x = 23.
Part C: Explanation
In the given equation 3x + 15 = 84, the variable x represents the number of books Maria purchased. The equation states that the cost of x books at $3 each, represented by 3x, plus the cost of $15 for bookmarks, totals to $84. Thus, the value of x represents the number of books Maria bought in this scenario. In the solution, x = 23, it means Maria purchased 23 books for her book club.

Use one of De Morgan's Laws to write the negation of the statement. I said no, while she said yes. What is the negation? A. I did not say no while she did not say yes. B. I said yes while she said no. C. I said yes or she said no. D. I did not say no or she did not say yes.
The correct answer is B. De Morgan's Laws state that the negation of a conjunction is the disjunction of the negations of the individual statements.
In this case, the original statement is a conjunction ("I said no and she said yes"), so we can use De Morgan's Laws to get the negation as a disjunction ("I did not say no or she did not say yes").
De Morgan's laws are two rules in Boolean algebra that relate to the negation of logical expressions.
However, we also need to switch the individual statements and negate them, which gives us "I said yes and she said no."
Therefore, option B is the correct negation of the original statement.

A jet ski rental charges a flat rate of $75, plus an additional $10 per hour. You only have $200 to spend. How many hours can you rent the jet ski?
PLS HELP ME
Answer:
12.5 hours
Step-by-step explanation:
The flat rate is the base, in which no matter how long you rent it for, they'll still charge you that much. You have 200 dollars, and negative 75 is 125 dollars, which you can spend on the hours. Assuming you can rent the jet ski for half an hour, you can divide 125 by 10 for the amount of hours, and the answer is 12.5 hours. However, if you can't rent the jet skis for half an hour, the answer is 12 hours.
