Answer:
x ≈ 9.8
Step-by-step explanation:
using the cosine ratio in the right triangle
cos35° = \(\frac{adjacent}{hypotenuse}\) = \(\frac{x}{12}\) ( multiply both sides by 12 )
12 × cos35° = x , then
x ≈ 9.8 ( to the nearest tenth )
Solve the differential equation y'=1-y^2 Solve for y and explain your answer. Also state the equilibrium and nonequilibrium solutions.
y(x) = tan(x + C) where C is an arbitrary constant of integration. Thus, the equilibrium solutions are y = 1 and y = -1. The non-equilibrium solutions are the values of y that make y' not equal to 0.
EQUILIBRIUM AND NON-EQUILIBRIUMThe general solution to the differential equation y' = 1 - y² is:y(x) = tan(x + C)
Where C is an arbitrary constant of integration.
The equilibrium solutions are the values of y that make y' = 0, which occur when y² = 1. Thus, the equilibrium solutions are y = 1 and y = -1.The non-equilibrium solutions are the values of y that make y' not equal to 0. So the non-equilibrium solutions are the values of y that make y² different from 1, which are values of y that are not 1 or -1.The solution y(x) = tan(x + C) is a family of functions indexed by the arbitrary constant C. The constant C cannot be determined from the information given in the problem, and so the general solution contains all possible specific solutions.

Suppose a simple random sample of size nequals 150 is obtained from a population whose size is Upper N equals 30 comma 000 and whose population proportion with a specified characteristic is p equals 0.4 . (a) Describe the sampling distribution of ModifyingAbove p with caret . Choose the phrase that best describes the shape of the sampling distribution below. A. Approximately normal because n less than or equals 0.05 Upper N and np left parenthesis 1 minus p right parenthesis greater than or equals 10. Your answer is correct. B. Not normal because n less than or equals 0.05 Upper N and np left parenthesis 1 minus p right parenthesis greater than or equals 10. C. Not normal because n less than or equals 0.05 Upper N and np left parenthesis 1 minus p right parenthesis less than 10. D. Approximately normal because n less than or equals 0.05 Upper N and np left parenthesis 1 minus p right parenthesis less than 10. Determine the mean of the sampling distribution of ModifyingAbove p with caret . mu Subscript ModifyingAbove p with caret Baseline equals nothing (Round to one decimal place as needed.)
(a) Correct answer is Approximately normal because n less than or equals 0.05 Upper N and np left parenthesis 1 minus p right parenthesis greater than or equals 10.
(b) The value of P (X ≥ 770) is 0.0143.
(c) The value of P (X ≤ 720) is 0.0708.
Let X = number of elements with a particular characteristic.
The variable p is defined as the population proportion of elements with the particular characteristic.
The value of p is:
p = 0.74.
A sample of size, n = 1000 is selected from a population with this characteristic.
(a)
According to the Central limit theorem, if from an unknown population large samples of sizes n > 30, are selected and the sample proportion for each sample is computed then the sampling distribution of sample proportion follows a Normal distribution.
The mean of this sampling distribution of sample proportion is:
μ = p
The standard deviation of this sampling distribution of sample proportion is:
σ = \(\sqrt \frac{p(1-p)}{n}\)
The sample selected is of size, n = 1000 > 30.
Thus, according to the central limit theorem the distribution of is Normal, i.e. .
p~ N(μ = 0.74, σ =0.0139)
Thus the correct option is (A).
(b) We need to compute the value of P (X ≥ 770).
Apply continuity correction:
P (X ≥ 770) = P (X > 770 + 0.50)
= P (X > 770.50)
Then,
p > 770.5/1000 = 0.7705
Compute the value of P( p > 0.7705) as follows:
P( p > 0.7705) = P(p -μ/σ > 0.7705 - 0.74/0.0139)
= P( Z > 2.19)
= 1 - P( Z< 2.19)
= 1 - 0.98574
= 0.01426
≈ 0.0143
Thus, the value of P (X ≥ 770) is 0.0143.
(c)
We need to compute the value of P (X ≤ 720).
Apply continuity correction:
P (X ≤ 720) = P (X < 720 - 0.50)
= P (X < 719.50)
Then
Compute the value of as follows:
P( p < 0.7195) = P(p -μ/σ > 0.7705 - 0.74/0.0139)
= P(Z < - 1.47)
= 1 - P(Z < 1.47)
= 1 - 0.92922
= 0.07078
≈ 0.0708
Thus, the value of P (X ≤ 720) is 0.0708.

Find the prime factors of 60 by dividing by prime numbers.
Let's start with the smallest prime number 2
60/2 = 30
Divide that result over 2
30/2 = 15
We can't divide this by 2 because 15/2 = 7.5 isn't a whole number
Let's move onto 3
15/3 = 5
The result is a prime number, so we stop.
The values we divided as denominators were: {2, 2, 3}
We add the result 5 to the set to completely list all of the prime factors of 60
The prime factorization would be
60 = 2*2*3*5which is the same as saying
60 = 2^2*3*5A bakery sells two types of cakes, chocolate and vanilla. The chocolate cakes sell for $5 each, and the vanilla cakes sell for $3 each. If the bakery sold a total of 50 cakes and earned $200 in total sales, how many of each type of cake did they sell?
Step-by-step explanation:
Let's use "x" to represent the number of chocolate cakes sold and "y" to represent the number of vanilla cakes sold.
From the problem statement, we know that the bakery sold a total of 50 cakes, so we can set up an equation:
x + y = 50
We also know that the total sales were $200. If the chocolate cakes sold for $5 each and the vanilla cakes sold for $3 each, we can set up another equation for the total sales:
5x + 3y = 200
We can use the first equation to solve for one of the variables in terms of the other. For example, we can solve for y in terms of x:
y = 50 - x
Substituting this expression for y into the second equation, we get:
5x + 3(50 - x) = 200
Simplifying this equation, we get:
2x + 150 = 200
2x = 50
x = 25
So the bakery sold 25 chocolate cakes. To find the number of vanilla cakes sold, we can substitute x = 25 into the equation y = 50 - x:
y = 50 - 25
y = 25
So the bakery also sold 25 vanilla cakes.
Therefore, the bakery sold 25 chocolate cakes and 25 vanilla cakes.

Compute the z score for the applicant. Applicant's score 21.0; Mean 18.0; Standard Deviation - 3.0 O2.0 O-10 10 O-20 O None of these
To compute the z-score for the applicant, we can use the formula:
z = (x - μ) / σ
Where:
x is the applicant's score
μ is the mean
σ is the standard deviation
Given that the applicant's score is 21.0, the mean is 18.0, and the standard deviation is -3.0, we can substitute these values into the formula to calculate the z-score.
z = (21.0 - 18.0) / (-3.0)
z = 3.0 / -3.0
z = -1.0
Therefore, the z-score for the applicant is -1.0.
The correct option is O-10.

A registered golden retriever has a litter of 11 puppies. Assume that the probability of a puppy being male is 0.5. What is the probability at least 7 of the puppies will be male?
The probability at least 7 of the puppies will be male is approximately 0.0805 or 8.05%.
To determine the probability that at least 7 of the puppies will be male, we will have to use the binomial probability formula.
P(X ≥ k) = 1 - P(X < k)
where X is the number of male puppies, P is the probability of a puppy being male and k is the minimum number of male puppies required.
We can solve this problem by finding the probability that 0, 1, 2, 3, 4, 5, or 6 of the puppies are male, and then subtracting that probability from 1. We use the binomial distribution formula to find each of these individual probabilities.
P(X=k) = nCk * pk * (1-p)n-k
where n is the total number of puppies, p is the probability of a puppy being male (0.5), k is the number of male puppies, and nCk is the number of ways to choose k puppies out of n puppies. We'll use a calculator to compute each probability:
P(X < 7) = P(X=0) + P(X=1) + P(X=2) + P(X=3) + P(X=4) + P(X=5) + P(X=6)
P(X = 0) = 11C0 * 0.5⁰ * (1-0.5)¹¹ = 0.00048828125
P(X = 1) = 11C1 * 0.5¹ * (1-0.5)¹⁰ = 0.00537109375
P(X = 2) = 11C2 * 0.5² * (1-0.5)⁹ = 0.03295898438
P(X = 3) = 11C3 * 0.5³ * (1-0.5)⁸ = 0.1171875
P(X = 4) = 11C4 * 0.5⁴ * (1-0.5)⁷ = 0.24609375
P(X = 5) = 11C5 * 0.5⁵ * (1-0.5)⁶ = 0.35595703125
P(X = 6) = 11C6 * 0.5⁶ * (1-0.5)⁵ = 0.32421875
P(X < 7) = 0.00048828125 + 0.00537109375 + 0.03295898438 + 0.1171875 + 0.24609375 + 0.35595703125 + 0.32421875 = 1 - P(X < 7) = 1 - 1.08184814453 = -0.08184814453 ≈ 0.0805
Therefore, the probability that at least 7 of the puppies will be male is approximately 0.0805 or 8.05%.

What is the division property or something like that?
The division property refers to a fundamental principle in mathematics that allows us to divide both sides of an equation or inequality by the same non-zero value without changing the truth of the statement.
The division property is a fundamental concept in mathematics that stems from the symmetric property of equality. It states that if we have an equation or inequality, we can divide both sides by the same non-zero value to maintain equality or inequality.
For example, if we have the equation 2x = 8, we can apply the division property by dividing both sides by 2. This yields x = 4, which is the solution to the equation. Similarly, in the inequality 3y < 9, we can divide both sides by 3 to obtain y < 3, preserving the direction of the inequality.
The division property is a powerful tool that allows us to simplify equations and inequalities, isolate variables, and solve mathematical problems. However, it is crucial to remember that the division property is only valid when dividing by a non-zero value. Dividing by zero is undefined in mathematics and can lead to errors and contradictions. Therefore, we must exercise caution and ensure we are dividing by a non-zero value when applying the division property.

Answer:
F) 1, -1
Step-by-step explanation:
You want the real solutions to |x|² +2|x| -3 = 0.
SolutionWe can let z = |x|. Then the equation becomes ...
z² +2z -3 = 0
(z +3)(z -1) = 0 . . . . . factored
The solutions will be the values of z that make the factors zero:
z +3 = 0 ⇒ z = -3
z -1 = 0 ⇒ z = 1
Z = -3Substituting our definition of z, we have ...
|x| = -3
The absolute value is never negative, so there are no values of x that satisfy this equation.
Z = 1Substituting our definition of z, this is ...
|x| = 1
This is true for x = ±1.
The real solutions to the equation are 1, -1.

a. Will this function have a maximum or a minimum? How can you tell?
b. According to this model, in what year will the percent of homes with broadband Internet access be at its maximum or minimum?
c. What is the predicted maximum/minimum percent of homes with broadband Internet access?
Answer:
a) The function has a maximum at x = 29,59
b) 99,32 %
Step-by-step explanation:
f(x) = -0,11*x² + 6,51*x + 3
Then:
f´(x) = -0,22*x + 6,51
If f´(x) = 0 then - 0,22*x + 6,51 = 0
0,22*x = 6,51
x = 6,51/0,22 ⇒ x = 29,59
if we get the second derivative
f´´(x) = - 0,22 f´´(x) < 0 then we have a maximun at x = 29,59
a) the function has a maximum
b) 29,59 years after 2000 ( in 2030 )
c) f(x) = - 0,11*x² + 6,51*x + 3
f(29,59) = - (0,11)* (29,59)² + 6,51*29,59 + 3
f(29,59) = 99,32 %

Let's denote the cost of a large pizza as CC and the number of toppings as TT. From the given information, we have the following two scenarios:
A large pizza with 2 toppings costs $13.50.
This can be represented as the ordered pair (2,13.50)(2,13.50).
A large pizza with 5 toppings costs $17.75.
This can be represented as the ordered pair (5,17.75)(5,17.75).
To find the equation representing the situation, we need to determine the additional charge per topping. Let's denote this charge as AA
From the given information, we can set up two equations:
C+2A=13.50C+2A=13.50 (for the first scenario)
C+5A=17.75C+5A=17.75 (for the second scenario)
Solving this system of equations, we find that C=10C=10 and A=1.75A=1.75.
