Answer:
x=7.5
Step-by-step explanation:
To cancel out the sin function we need to mulitplly it by sin⁻¹ (you can usually access this button if you press 2nd-->sin)
so sin⁻¹(.5)=30
30=4x
x=7.5

The width of a rectangle is 3 units less than the length. The area of the rectangle is 4 Units What is the length, in units, of the rectangle?
Answer: 4 units
Step-by-step explanation: IT cant be 2x2 or else it would be a square
so it would have to be that the width is 1 unit and the lenght is 4 units.

Josephine is taking a college course, and her professor bases the course grade on the average of 2 tests taken in the semester. She wants to know what she needs to earn on the last test to maintain her grade. Rearrange the following equation for b, where C is the average of 2 test scores, a and b.
C equals the quantity a plus b all over two
b equals two times C over a
b = 2C + a
b = 2C − a
b = 2C(a)
Answer:
Hi i know im very late answering this question but i believe the correct option is: b = 2C - a
Step-by-step explanation:
I believe this is the answer because:
2C = the average of 2 test scores combined
A and B = the two scores
were trying to solve for b so what we would do to figure that out is have the average of both test scores and then subtract A which will leave you with only B. therefor the answer is B = 2C - a

When factoring the difference of two squares, what will the signs in the parenthesis be
Answer:
The signs will be + and -
Step-by-step explanation:
Required
The signs in the parenthesis of difference of two squares
Let the expression be:
[tex](x^2 - a^2)[/tex]
Expand
[tex]x^2 - a^2 = x^2 -ax + ax - a^2[/tex]
Factorize
[tex]x^2 - a^2 = x(x -a) + a(x - a)[/tex]
Factor out x - a
[tex]x^2 - a^2 = (x +a)(x - a)[/tex]
See that the sign in front of a is + and - in the parentheses

Suppose that 50% of the watches produced by a certain factory are defective. A store buys a box with 400 watches produced by this factory. Assume That this is a random sample.(a) Write an expression for the exact probability that at least 215 watches out ofthe 400 are defective. You do not need to numerically evaluate it.(b) Argue whether the normal or the Poisson approximation is appropriate to es-timate the above probability and then estimate it.
Answer:
[tex](a)\ P(x \ge 215)[/tex]
[tex](b)\ P(x \ge 214.5) = 0.07353[/tex]
Step-by-step explanation:
Given
[tex]p = 0.50[/tex] ---- proportion of watches with defects
[tex]n = 400[/tex] --- Number of watches
Solving (a): Represent at least 215 of 400 are defective
In inequalities, at least means: [tex]\ge[/tex]
So, the probability is represented as: [tex]P(x \ge 215)[/tex]
Solving (b): Calculate [tex]P(x \ge 215)[/tex]
Normal or Poisson: Normal distribution is characterized by 2 parameters [tex]\mu[/tex] and [tex]\sigma[/tex].
These two parameters can be easily calculated from the given parameters in the question. So, we solve using normal distribution
Start by calculating the mean
[tex]\mu =np[/tex]
[tex]\mu = 0.50 * 400[/tex]
[tex]\mu = 200[/tex]
Calculate standard deviation
[tex]\sigma = \sqrt{\mu (1 - p)[/tex]
[tex]\sigma = \sqrt{200 * (1 - 0.50)[/tex]
[tex]\sigma = \sqrt{200 * 0.50[/tex]
[tex]\sigma = \sqrt{100[/tex]
[tex]\sigma = 10[/tex]
By continuity correction, we have:
[tex]x \to x - 0.5[/tex]
[tex]x \to 215 - 0.5[/tex]
[tex]x \to 214.5[/tex]
So, we have:
[tex]P(x \ge 215) = P(x \ge 214.5)[/tex]
Calculating [tex]P(x \ge 214.5)[/tex], we have:
[tex]P(x \ge 214.5) = 1 - P(x < z)[/tex]
Calculate z score
[tex]z = \frac{x - \mu}{\sigma}[/tex]
[tex]z = \frac{214.5 - 200}{10}[/tex]
[tex]z = \frac{14.5}{10}[/tex]
[tex]z = 1.45[/tex]
So, we have:
[tex]P(x \ge 214.5) = 1 - P(x < 1.45)[/tex]
Using the z score probability table, we have:
[tex]P(x < 1.45) = 0.92647[/tex]
So, we have:
[tex]P(x \ge 214.5) = 1 - 0.92647[/tex]
[tex]P(x \ge 214.5) = 0.07353[/tex]

3. Create a Venn diagram or Table with numbers for:
A group of 80 students were asked if they were taking science or art.
10 were taking neither, 50 were taking science, 30 were taking art.
Answer:
10 students were taking science and art at the same time.
Step-by-step explanation:
Given that a group of 80 students were asked if they were taking science or art, of which 10 were taking neither, 50 were taking science, and 30 were taking art, to determine how many students take both science and art, the following calculation must be done:
80 - 10 = 70
50 - 30 - 70 = X
80 - 70 = X
10 = X
Therefore, 10 students were taking science and art at the same time.

A=
Answer:
a] Radius of circle = 10 feet
Circumference of circle = 94.2 feet (Approx.)
Area of circle = 314 feet² (Approx.)
b] Radius of circle = 6 cm
Circumference of circle = 37.68 cm (Approx.)
Area of circle = 113.04 cm² (Approx.)
Step-by-step explanation:
Given:
a] Radius of circle = 10 feet
b] Radius of circle = 6 cm
Find:
Circumference an area for both circle
Computation:
Circumference of circle = 2πr
Area of circle = πr²
a] Radius of circle = 10 feet
Circumference of circle = 2(3.14)(10)
Circumference of circle = 94.2 feet (Approx.)
Area of circle = (3.14)(10)²
Area of circle = 314 feet² (Approx.)
b] Radius of circle = 6 cm
Circumference of circle = 2(3.14)(6)
Circumference of circle = 37.68 cm (Approx.)
Area of circle = (3.14)(6)²
Area of circle = 113.04 cm² (Approx.)

Answer:
B. 4
Step-by-step explanation:
∠4 is an alternate exterior angle with ∠2 because both angles are on the exterior of the lines, and lie on opposite ends on the transversal.
The angle that is an alternate exterior angle with angle 2 is angle 4.
What are Parallel lines?Parallel lines are those lines that are equidistance from each other and never intersect each other.
Given that;
The figure is shown in figure.
Now,
Since, ∠4 is an alternate exterior angle with ∠2 because both angles are on the exterior of the lines, and lie on opposite ends on the transversal.
Hence, ∠4 is an alternate exterior angle with angle 2.
Thus, The angle that is an alternate exterior angle with angle 2 is angle 4.

Find the circumference of circle with a radius of 17 yards
Round to the nearest hundredth (Use 2 decimal places)
QUESTION 3
in that has a diameter of 10
Answer: 106.76yards
Step-by-step explanation:
Circumference of a circle is given as:
= 2πr
where,
π = 3.14
r = 17 yards
Circumference = 2πr
= 2 × 3.14 × 17.
= 106.76yards
Therefore, the circumference of the circle will be 106.76yards
Hi, i need to calculate roots x1 and x2 using the vieta theorem, can anyone help me?

I have left a similar equation that i did. The only thing why i cant do the equation, because in front of x2 there’s an number, so i don’t understand.

Step-by-step explanation:
You can put the domain values into the function and evaluate to find the corresponding range values. Here, we'll do them "all at once."
y = 3{-4, -1, 2, 5} +5
= {-12, -3, 6, 15} +5
= {-7, 2, 11, 20} . . . . . matches choice d

To save yourself some arithmetic, you can observe that the answer choices differ in the 2nd and 4th values, so you only need to evaluate the function for x=-1 or x=5 to determine the correct answer choice.
