Rewrite the expression in terms of sine and cosine, and simplify as much as possible. (sec w(1+ csc^2 w))/(csc^2 w)
Answer:
(sin^2 w + 1) / cos w.
Step-by-step explanation:
Note: sec w = 1 / cos w and csc w = 1/ sin w.
So we have:
(sec w(1 + csc^2 w)) / (csc^2 w)
= 1/cos w ( 1 + 1/ sin^2 w) / (1 / sin^2 w)
= ( 1/ cos w + 1 / sin^2 w cos w) * sin^2 w
= sin^2 w/ cos w + sin^2 w / (sin^2 w cos w)
= sin^2 w / cos w + 1 / cos w
= (sin^2 w + 1) / cos w.
Jason is cutting a roll of sausage into pieces that are 1/2 inches thifk if the roll is 6 inchew long how many pieces of sausage can he. Cut use tiles to hlep to solve
Final answer:
Jason can cut 12 pieces of sausage from the 6-inch roll, since dividing the roll's length by the thickness of each piece (6 inches ÷ 1/2 inch) yields 12 pieces.
Explanation:
To determine how many pieces of sausage Jason can cut from a roll that is 6 inches long, where each piece is 1/2 inches thick, one would perform a simple division.
The length of the sausage roll (6 inches) is divided by the thickness of each piece (1/2 inch) to find out how many pieces can be cut.
This is a basic fraction division problem that we solve by multiplying the length of the roll by the reciprocal of the thickness of the pieces to be cut.
Calculation
To calculate:
6 inches × 2/1 (which is the reciprocal of 1/2) equals 12.
So, Jason can cut 12 half-inch-thick pieces from the 6-inch roll.
Alex doesn't remember what the Zero Product Property is used for. Explain to Alex what the property is and how it is used.
The Zero Product Property in mathematics states that if the product of two numbers is zero, then at least one of the numbers must be zero. You typically use this property when solving quadratic equations by setting each factored term equal to zero and then solving for every variable.
Explanation:The Zero Product Property is an essential concept in algebra, particularly when it comes to solving quadratic equations. The Zero Product Property states that if the product of two numbers, terms, or factors is zero, then at least one of the factors must be zero. In simple terms, if a * b = 0, then a has to be zero, or b has to be zero, or both.
To use the Zero Product Property, you usually start by setting an equation equal to zero. For example, let's solve the quadratic equation x^2 - 5x = 0. First, you would factor the equation to (x)(x-5) = 0. Now, using the Zero Product Property, we can set each factor equal to zero and solve for x. This gives us x = 0 and x = 5.

Which of the following is the correct radical form of this expression
ANSWER
The correct answer is A.
EXPLANATION
The given expression is
[tex]( \frac{ {p}^{12} {q}^{ \frac{3}{2} } }{64} ) ^{ \frac{5}{6} } [/tex]
Recall that:
[tex] {a}^{ \frac{m}{n} } = (\sqrt[n]{a} ) ^{m} [/tex]
For the given expression,
[tex]m = 5[/tex]
[tex]n = 6[/tex]
and
[tex]a = \frac{ {p}^{12} {q}^{ \frac{3}{2} } }{64} [/tex]
We substitute all these values to obtain the radical form:
[tex]( \frac{ {p}^{12} {q}^{ \frac{3}{2} } }{64} ) ^{ \frac{5}{6} } = ( \sqrt[6]{( \frac{ {p}^{12} {q}^{ \frac{3}{2} } }{64} ) })^{5} [/tex]

The sum of two integers is 23 and the positive difference of the same two integers is 13. What is the product of these two integers?
A) 90 B) 75
C) 46 D) 299
Answer:
A) 90
Step-by-step explanation:
"The sum of two integers is 23" becomes
a + b = 23
"the positive difference of the same two integers is 13" becomes
a - b = 13 (difference means subtract)
Now solve the system..
a + b = 23
a - b = 13 *use addition or elimination method, since b has opposite coefficients...
2a = 36 ( we add the two equations together)
a = 18 (divide by 2 on both sides)
Since a = 18, 18 + b = 23, gives us b = 5. (18 + 5 = 23)
ab = (18)(5) = 90
Answer: A) 90
Let one integer is = x.
Sum of them is 23. So the other integer is (23 - x).
Given: Difference = 13.
So,
[tex]x-(23-x)=13\\ x-23+x=13\\ 2x=36\\ x=18[/tex]
So the other number is = 23 - x = 23 - 18 = 5.
So the product = 18*5=90

Select each correct answer. When a card is chosen at random with replacement five times, X is the number of times a prime number is chosen. When a card is chosen at random without replacement three times, X is the number of times an even number is chosen. When a card is chosen at random with replacement six times, X is the number of times a 3 is chosen. When a card is chosen at random with replacement multiple times, X is the number of times a card is chosen until a 5 is chosen.
Answer:
When a card is chosen at random with replacement five times, X is the number of times a prime number is chosen; When a card is chosen at random with replacement six times, X is the number of times a 3 is chosen.
Step-by-step explanation:
In a binomial distribution, there are only two outcomes, or outcomes that can be reduced to 2. In the first choice, we either draw a prime number or do not draw a prime number. In the third choice, we either draw a 3 or do not draw a 3.
There must be a fixed number of trials. In the first choice, we have 5 trials; in the third option, we have 6 trials.
The trials must be independent of each other. Since the cards in the first and third options are drawn with replacement, the outcome of one trial does not influence the probability of the next trial.
The probability must be the same for every trial. This is true of the first and third options.

Select all of the following true statements if R = real numbers, Z = rational numbers, and W = {0, 1, 2, ...}.
WZ
RZ
-1 W
R
{0, 1, 2, ...} W
0 Z
Answer:
We can start solving this problem by first identifying what the elements of the sets really are.
R is composed of real numbers. This means that all numbers, whether rational or not, are included in this set.
Z is composed of integers. Integers include all negative and positive numbers as well as zero (it is essentially a set of whole numbers as well as their negated values).
W on the other hand has 0,1,2, and onward as its elements. These numbers are known as whole numbers.
W ⊂ Z: TRUE. As mentioned earlier, Z includes all whole numbers thus W is a subset of it.
R ⊂ W: FALSE. Not all real numbers are whole numbers. Whole numbers must be rational and expressed without fractions. Some real numbers do not meet this criteria.
0 ∈ Z: TRUE. Zero is indeed an integer thus it is an element of Z.
∅ ⊂ R: TRUE. A null set is a subset of R, and in fact every set in general. There are no elements in a null set thus making it automatically a subset of any non-empty set by definition (since NONE of its elements are not an element of R).
{0,1,2,...} ⊆ W: TRUE. The set on the left is exactly what is defined on the problem statement for W. (The bar below the subset symbol just means that the subset is not strict, therefore the set on the left can be equal to the set on the right. Without it, the statement would be false since a strict subset requires that the two sets should not be equal).
-2 ∈ W: FALSE. W is just composed of whole numbers and not of its negated counterparts.
Step-by-step explanation:
Certain elements and sets are examined for their relationships with the sets of real numbers, integers, and whole numbers; identifying which elements belong to which sets and if one set is a subset of another.
When comparing different sets of numbers, we analyze whether one set is a subset of another and whether certain elements belong to specific sets. The given question involves the sets R (real numbers), Z (integers), and W = {0, 1, 2, ...}, also known as the set of whole numbers or non-negative integers.
→ W ⊂ Z: This is true because all elements of W are non-negative integers, which are a subset of Z, the set of all integers including negative, zero and positive whole numbers.
→ R ⊂ W: This is false because the set of real numbers includes irrational numbers as well as negative numbers, which are not included in W.
→ 0 ∈ Z: This is true because zero is an integer and, therefore, is an element of Z.
→ ∅ ⊂ R: This is true because the empty set is a subset of all sets, including the set of real numbers.
→ {0, 1, 2, ...} ⊆ W: This is true because this set is exactly W itself, and a set is always a subset of itself.
→ -2 ∈ W: This is false because W contains only non-negative integers, and -2 is a negative number.

Step-by-step explanation:
The given logarithmic expression is:
[tex]\log_2(\sqrt[5]{16} )[/tex]
We rewrite the radical as an exponent to obtain;
[tex]\log_2(\sqrt[5]{16} )=\log_2(16^{\frac{1}{5}} )[/tex]
Recall and use the power rule; [tex]\log_a(M^n)=n\log_a(M)[/tex]
[tex]\log_2(\sqrt[5]{16} )=\frac{1}{5}\log_2(16 )[/tex]
We write 16 as an index number to base 2.
[tex]\log_2(\sqrt[5]{16} )=\frac{1}{5}\log_2(2^4)[/tex]
We apply the power rule again;
[tex]\log_2(\sqrt[5]{16} )=\frac{4}{5}\log_2(2)[/tex]
We simplify to get;

For 1 and 2, state whether the numbers are parameters or statistics, and use the appropriate notation to describe each number. 1. a random sample of female college students has a mean height of 64.5 inches, which is greater than the 63-inch mean height of all adult american women.
Answer:
x-bar 64.5 is a statistic because it describes a sample.
Mu 63 is a parameter because it describes a population.
The symbol for mu is a Greek m
Step-by-step explanation:
Final answer:
A random sample mean, like the 64.5 inches height for female college students, is a statistic denoted as \( \bar{x} \), while the mean height of all adult American women is a parameter denoted as \( \mu \). Determining whether a number is a parameter or statistic informs how it is used in hypothesis testing and confidence interval construction.
Explanation:
When identifying whether the numbers are parameters or statistics, it's important to distinguish between data collected from a population or a sample. In the scenarios mentioned, such as when a random sample of female college students has a mean height of 64.5 inches, we are dealing with a statistic. This is because it is a measure obtained from a sample. The appropriate notation for this sample mean would be \( \bar{x} \). This contrasts with the information such as the mean height of all adult American women, which is a parameter because it relates to the entire population. The notation for a population mean is \( \mu \). Considering other examples provided, when we calculate a p-value or when we undertake a study and calculate the difference in mean heights between groups, we are dealing with statistics.
In practice, the difference between statistics and parameters is essential for hypothesis testing, constructing confidence intervals, and making inferences about the population based on sample data. For example, if the p-value is close to zero in a test related to the mean height of high school basketball players, it suggests that there is strong evidence against the null hypothesis \( H_0 \), which posits no effect or no difference. The alternative hypothesis \( H_1 \) would be that there is a significant difference.

Do you think that a 270° clockwise rotation is the same as a 90° counterclockwise rotation? Explain why or why not.
Answer: This would equal the same distance
Explanation: Think of a clock if it rotates 90 degrees counter clockwise it would stop at the number 9. If it rotates 90 clockwise it would stop at 3, then rotate that hand clockwise by 90 degrees one more time it will stop at 6, then 9 at 270 degrees.
Answer:
sorry if im late but this is the answer:
Step-by-step explanation:
Yes, I think they are the same. One revolution is 360 degrees. A 180-degree clockwise rotation is the same as a 180-degree counterclockwise rotation. The sum of the measures is 360. So, moving in a clockwise direction for 270 degrees would end at the same place as moving 90 degrees in a counterclockwise direction.

Jody practiced a piano piece for 500 seconds bill practiced a piano piece for 8 minutes who practiced longer explain
Answer:
Jody
Step-by-step explanation:
You can either convert 500 seconds to minutes or 8 minutes to seconds to compare. I'll do both.
There is 60 seconds in a minute. To find the total minutes of 500 seconds, divide 500 by 60 → 8.3, which means that Jody practiced for 8.3 minutes.
To find the total seconds of 8 minutes, multiply 60 seconds per minute by 8 minutes → 60 * 8 = 480 seconds which means that Bill practiced for 480 seconds.
Now you can compare. Jody practiced for 500 seconds, or 8.3 minutes. Bill practiced for 480 seconds, or 8 minutes. Jody practiced longer.

Thirty Mercedes and Audi participated in a 30 mile race. The average driving speed of the Mercedes and Audi were recorded. A random sample (Sample 1) of the Mercedes's average driving speed (km/h) is: 120, 142, 142, 165, 132, 130, 156, 136, 167, 139, 144. A random sample (Sample 2) of the Audi's average driving speed (km/h) is: 112, 145, 146, 165, 163, 141, 112, 134, 113, 114, 125. What is the median of Sample 1? What is the median of Sample 2?
Answer:
Median for sample 1 = 142
Median for sample 2 = 134
Step-by-step explanation:
For Sample 1:
For finding median, the data is first arranged into ascending or descending order. We are arranging the data in ascending order.
120, 130, 132, 136, 139, 142, 142, 144, 156, 165, 167
The formula for calculating the term which will be median is:
Median= ((n+1)/2)
Here in sample 1, n=11
So, putting n=11 in the formula
= ((11+1)/2)
= (12/2)
=6th term
The sixth term is 142, so
Median of sample 1=142
For Sample 2:
For finding median, the data is first arranged into ascending or descending order. We are arranging the data in ascending order.
112, 112, 113, 114, 125, 134, 141, 145, 146, 163, 165
The formula for calculating the term which will be median is:
Median= ((n+1)/2)
Here in sample 2, n=11
So, putting n=11 in the formula
=((11+1)/2)
=(12/2)
=6th term
The sixth term is 134, so
Median of sample 2=134
