Answer: -1/2
Step-by-step explanation:
Because the degrees given is greater than 360, we must find out what its simplest degree is. The easiest way to do this is to find the remainder of the argument divided by 360.
So let's start by doing 930 / 360. This will give you a remainder of 210 degrees. So now we are finding sin 210 degrees.
Remember that sin is the y-values of the unit circle. From 0 < θ < 180, sin θ is positive, so we automatically know it must be a negative answer. Now, 210 is 30 degree below the x-axis, meaning that coordinate pair of (cos 210 degrees, sin 210 degrees) is (-sqrt(3)/2 , -1/2). Tje y-value, -1/2, is your answer.

The value of x is 19 and the measure of angles in triangle ABC are 75°, 75° and 30° respectively.
What is a triangle?triangle is a three-sided polygon that consists of three edges and three vertices. The most important property of a triangle is that the sum of the internal angles of a triangle is equal to 180 degrees. This property is called angle sum property of triangle.
If ABC is a triangle, then it is denoted as ∆ABC, where A, B and C are the vertices of the triangle. A triangle is a two-dimensional shape, in Euclidean geometry, which is seen as three non-collinear points in a unique plane.
The sum of ∠A + ∠B + ∠C = 180°( sum of angles in a triangle )
3x + 18 + 7x - 58 + 2x - 8 = 180°
12x -48° = 180°
12x = 228
x = 228/12
x = 19
but ∠A = 3x + 18, but x = 19
∠A = 3(19) + 18 which is 75°
Also ∠B = 7x -58
∠B = 7(19) - 58 which is 75°
∠C = 2x -8
∠C = 2(19) - 8 which is 30°
In conclusion, the value of x = 19, ∠A = 75°, ∠B = 75° ∠C = 30°

Answers
The responses for the confidence intervals of the 45 lbs weight and the set of data are;
3. D. (45.0472, 45.0928); The exercise equipment company can be 95% confident the population mean of their 45 lb weights lies between 45.0472 and 45.0928
4. C. The size of the confidence interval would increase because Raul would be multiplying by a larger z-score and dividing by a smaller sample size.
What is a confidence interval?The confidence interval is the likelihood of a parameter of a population can be found within a range of values during a specified percentage or proportion of the time.
3. The confidence interval can be found using the formula;
[tex]CI = \overline x \pm z\cdot \dfrac{s}{\sqrt{n} }[/tex]
Where;
[tex]\overline x[/tex] = The mean of the sample = 45.07 lbs
s = The standard deviation of the sample = 0.09 lbs
n = The sample size
z = The confidence level = 1.96 at 95% confidence level
Therefore;
[tex]CI = 45.07 \pm 1.96\times \dfrac{0.09}{\sqrt{60} }[/tex]
45.0472 < μ < 45.0928
The correct option is therefore, option D
Therefore;
The company can be 95% sure that the mean of the population of the 45 lb weights are between 45.0472 and 45.0928 lbs4. Decreasing the sample size, n, will decrease the value by which the term on the right of the ± is being divided, increasing the confidence interval.
Increasing the level of confidence will increase z, thereby also increasing the confidence interval.

A function, according to a technical definition, is a relationship between a set of inputs and a set of potential outputs, where each input is connected to precisely one output.
This means that a function f will map an object x to exactly one object f(x) in the set of potential outputs if the object x is in the set of inputs (referred to as the domain) (called the codomain).
The metaphor of a function machine, which accepts an object as its input and produces another object as its output based on that input, makes the concept of a function simple to understand.

Cindy is attempting to calculate how much her car payment would be for a car that costs $27,000 to be repaid with monthly payments in 4 years at 4% APR.
Answers
Cindy's monthly payment of $609.63 will cost her $29,262.24 in 4 years at a 4% APR.
How is the total cost determined?The total cost that Cindy will spend on the car which costs $27,000 is computed by multiplying the monthly payment by 48 months (the payment period).
The monthly payment can be determined using an online finance calculator that compounds the interest rate monthly for four years.
Cost of car = $27,000
Annual Percentage Rate (APR) = 4%
Payment period = 4 years (monthly)
N (# of periods) = 48 months (4 years x 12)
I/Y (Interest per year) = 4%
PV (Present Value) = $27,000
FV (Future Value) = $0
Results:
PMT = $609.63
Sum of all periodic payments = $29,262.24
Total Interest = $2,262.45
Thus, Cindy will spend $29,262.24 for a car that costs $27,000, if she repays monthly for 4 years.

6x-15=90-9×
6x+9x=90+15
15x=105
×=7
Answer:
x = 7
Step-by-step explanation:
1. Distribute
3(2x - 5) = 9(10 - x)
6x - 15 = 9(10 - x)
2. Rearrange Terms
6x - 15 = 9(10 - x)
6x - 15 = 9(-x + 10)
3. Distribute
6x - 15 = 9(-x + 10)
6x - 15 = -9x + 90
4. Add 15 to both sides
6x - 15 = -9x + 90
6x - 15 + 15 = -9x + 90 + 15
5. Simplify
Add the numbers:
6x - 15 + 15 = -9x + 90 + 15
6x = -9x + 90 + 15
Add the numbers:
6x = -9x + 90 + 15
6x = -9x + 105
6. Add 9x to both sides
6x = -9x + 105
6x + 9x = -9x + 105 + 9x
7. Simplify
Combine like terms:
6x + 9x = -9x + 105 + 9x
15x = -9x + 105 + 9x
Combine like terms:
15x = -9x + 105 + 9x
15x = 105
8. Divide both sides by the same factor
15x = 105
15x/15 = 105/15
9. Simplify
Cancel terms that are in both the numerator and denominator:
15x/15 = 105/15
x = 105/15
Divide the numbers:
x = 105/15

Divide the numerator and denominator by the GCF to reduce a fraction. (This is also referred to as "writing a fraction in the simplest terms.") The common factors are sometimes shown to be "cancelled." It is worth noting that the result is an equivalent fraction in its simplest form.
How do you divide the numerator to the denominator by GCF?To put it simply, we must divide the numerator (x) by the denominator (y) to simplify it. For example, after simplifying 3 6, represent it as a fraction and identify the numerator and denominator. 3 6 can be written as 3/6. Further simplification yields 1/2.
Let's pretend the fraction is a proper fraction. The denominator is the numerator. We want to reduce the fraction to its simplest form.
a) Use Numerator =Remainder* as the denominator.

d) When the Remainder equals zero, the Divisor is the GCD (or GCF, as you say). GCF is a misnomer because it only deals with numbers. Only the term GCF applies to variables (with numerical values, as in algebraic expression).
Let us look at an example.
407/3367 is the fraction.
As evident, the numbers407 ,3367 does not appear to have share Divisors 2 or 3 or 5 or 7 or 11 from prima facie considerations. So we may take recourse of successive division method.
3367 ÷407 =Remainder 111 (quotient 8)
407 ÷ 111 =Remainder 74 (quotient 3)
111 ÷74=Remainder 37 (quotient 1)
74 ÷37 =Remainder 0 (ZERO )
Here 37 divides leaving Remainder zero. Therefore the GCD is 37

what is the fourth term of d 4b3
Answers
The fourth term of the polynomial (d - 4b)³ is D. -64d³.
What is a polynomial?A polynomial is an expression involving the operations of addition, subtraction, multiplication of variables.
Given the expression (d - 4b)³, we need to open the bracket, hence:
(d - 4b)³ = d³ + 3(d²)(-4b) + 3(d)(-4b)²
= d³ - 12bd² + 48b²d - 64d³
Therefore, the fourth term of (d - 4b)³ is D. -64d³

Gert invested all of her money at the end of 2000. At the end of each year, she checks the value of her investment. At the end of what ear will she first find she's doubled her money if gert invested all of her money at 5% simple interest?
Answers
The year in which Gert will find that she has doubled her money is year 20.
What year will the amount have doubled?
Simple interest is when the interest earned on an investment increases linearly each year.
The formula that can be used to determine simple interest is:
Simple interest = amount invested x duration of the investment x interest rate.
When the amount of money in the account is double what it is now, it means that the interest earned would be $2000 and the value of the account would $4000 (2000 + 2000).
Year when investment would have doubled = simple interest / (amount invested x interest rate)
Year when investment would have doubled = $2000 / (0.05 x 2000)
Year when investment would have doubled = $2000 / 100 = 20 years
