Review the data and calculate the probability that someone with a credit score of 650 or below defaulted on the loan.

The trigonometric identity has been proven as 1 in the space below

Given the identity:

tan(1/2x) (2cot(x) + tan(1/2x)) = 1

To prove this identity, let's start by expressing cot(x) in terms of tan(x):

cot(x) = 1 / tan(x)

Now, replace cot(x) in the given identity:

tan(1/2x) (2(1/tan(x)) + tan(1/2x)) = 1

Now, let's use the double angle formula for tan(x):

tan(x) = 2 * tan(1/2x) / (1 - tan^2(1/2x))

Replace tan(x) in the equation:

tan(1/2x) (2(1/(2 * tan(1/2x) / (1 - tan^2(1/2x))) + tan(1/2x)) = 1

Simplify the equation:

tan(1/2x) ((1 - tan^2(1/2x)) + tan(1/2x) * tan(1/2x)) = 1

Now, notice that the expression in the parentheses is equal to 1:

(1 - tan^2(1/2x)) + tan^2(1/2x) = 1

So, we can simplify the equation further:

tan(1/2x) * 1 = 1

This directly leads us to the original identity:

tan(1/2x) = 1

Thus, the trigonometric identity is proven.

Therefore, a sharpening costs Dollar 1.85.

The US, Canada, Australia, and some nations in the Pacific, Caribbean, Southeast Asia, Africa, and South America all use the dollar as their primary unit of exchange. The word "$" is used to denote it.

Let's use $a for the sharpener's price. We can state that the price of a book is $a + 1.95 because it costs $1.95 more than a sharpening.

We are aware of the $26.10 total cost of 10 sharpeners and 2 books. This can be expressed as an equation:

10a + 2(a + 1.95) = 26.10

If we simplify this equation, we get:

12a + 3.90 = 26.10

3.90 less from each side results in:

12a = 22.20

By multiplying both sides by 12, you get:

a = 1.85

Therefore, a sharpening costs $1.85.

The expression for the velocity is v(t) = 30m/s

(a) x(t) = 30t

The velocity is the derivative of the position function with respect to time:

v(t) = dx/dt

Since x(t) = 30t, we have:

v(t) = d/dt (30t)

= 30

So the expression for velocity is v(t) = 30 m/s.

(b) x(t) = 7sin(30)

The velocity is the derivative of the position function with respect to time:

v(t) = dx/dt

Since x(t) = 7sin(30), we have:

v(t) = d/dt (7sin(30))

= 7cos(30) * d/dt (30t)

= 3.5cos(30)

So the expression for velocity is v(t) = 3.5cos(30) m/s.

(c) x(t) = ecos(701)

The velocity is the derivative of the position function with respect to time:

v(t) = dx/dt

Since x(t) = ecos(701), we have:

v(t) = d/dt (ecos(701))

= -e sin(701) * d/dt (701t)

= -701e sin(701t)

So the expression for velocity is v(t) = -701e sin(701t) m/s.

The solution set of f(x) > 0 is x ∈ (-2, 8).

To find the solution set of f(x) > 0, we need to first determine the critical values of x where f(x) changes sign.

Let's start by finding the domain of the function:

x² - 6x - 16 ≠ 0

We can solve for x by using the quadratic formula:

x = [6 ± √(6² + 4(16))]/2 = [6 ± √52]/2 = 3 ± √13

So the domain of f(x) is (-∞, 3 - √13) U (3 + √13, ∞).

Now let's factor the numerator and denominator of f(x):

f(x) = (x + 10)/[(x - 8)(x + 2)]

what is percent  ?

A percent is a way of expressing a number as a fraction of 100. The symbol for percent is %, which means "per hundred".

In the given question,

Let's assume that there are 100 people in Math town.

60% of them are males, so there are 60 males and 40 females.

Out of the 60 males, 30% have brown eyes, so there are 18 males with brown eyes.

28% of the entire population have brown eyes, so there are 28 people with brown eyes.

To find the number of females with brown eyes, we need to subtract the number of males with brown eyes from the total number of people with brown eyes:

28 - 18 = 10

So, there are 10 females with brown eyes.

Out of the 40 females in Math town, what percentage have brown eyes?

The Probability that a marble selected at random from the bag will NOT be green is 1/3

Step-by-step explanation:

The probability of selecting a green bag

                                           =8/12

Then the probability not of selecting a green bag  

                                                = 1 - The probability of selecting a green bag

                                                 = 1-(2/3)

The inequality that represents all possible values for the amount of money that Joann has is 21 ≤ J ≤ 50.

Let's call the amount of money that Joann has in her wallet "J" and the amount of money that Shana has in her wallet "S".

We know that the total amount of money they have is at least $56 and at most $85. Therefore, we can write two inequalities:

J + S ≥ 56 (the total is at least $56)

J + S ≤ 85 (the total is at most $85)

We also know that Shana has only $35 in her wallet. We can substitute this value for S in the inequalities to get an inequality that represents all possible values for the amount of money that Joann has:

J + $35 ≥ 56 (substituting S = $35 in the first inequality)

J + $35 ≤ 85 (substituting S = $35 in the second inequality)

Simplifying these inequalities by subtracting $35 from both sides, we get:

J ≥ 21 (the amount of money Joann has is at least $21)

J ≤ 50 (the amount of money Joann has is at most $50).

In the first triangle, the angle x = 45°

In the second triangle, the angle y = 75°

In the second triangle, the angle x = 45°

To find the angles in the triangles, we proceed as folows.

a. In the first triangle, let the base angle to the left be p. We know that we have a parallelogram there.

Now, in the parallelogram,

102° + p = 180°sum of (interior angles of a parallelogram)

So, p = 180° - 102°

= 78°

Now, in the larger triangle,

x + p + 57° = 180° (sum of angles in a triangle)

Since p = 78°, we have that

x + 78° + 57° = 180°

x + 135° = 180°

x = 180° - 135°

= 45°

So, x = 45°

b. In figure 2, we have two isoceles triangles.

i. In the first triangle, both base angles are y.

So, y + y + 30° = 180° (sum of angles in atriangle)

2y + 30° = 180°

2y = 180° - 30°

2y = 150°

y = 150°/2

y = 75°

So, y = 75°

ii. In the second triangle also, both base angles are x and the other angle is a right angle which is 90°.

So, x + x + 90° = 180° (sum of angles in a triangle)

2x + 90° = 180°

2x = 180° - 90°

2x = 90°

x = 90°/2

x = 45°

So, x = 45°

Probability is simply the possibility that something will happen. When we don't know how something will turn out, we can talk about the possibility of one outcome or the likelihood of several.

The study of events that fit into a probability distribution is known as statistics.

So, the likelihood that the average clock life would exceed 12.5 years:

This is the p-value of Z when X = 12.5 subtracted by 1.
