**Answer:**

the answer is 25 degrees

**Answer:**

alpha = 25°

**Step-by-step explanation:**

The picture indicates a rectangle.

Alpha is in a straight corner of 90 °, so...

65 + alpha = 90

subtract 65 left and right of the = sign.

65 - 65 + alpha = 90 - 65

0 + alpha = 90 - 65

alpha = 25°

The **linear equation **that models this situation is y = 30x

An equation is an **expression** showing the **relationship **between numbers and variables.

The** slope intercept f**orm of a straight line is:

y = mx + b

Where m is the **slope a**nd b is the y intercept.

The** standard form **of a straight line is:

Ax + By = C

Where A, B and C are constants

**Answer with Step-by-step explanation:**

We are given two input A and B

**A AND B=**

If A=0 and B=0 then

If A=0 and B=1 then

If A =1 and B=0 then

If A=1 and B=1 then

**A OR B=A+B**

If A=0 and B=0 then A+B=0+0=0

If A=0 and B=1 then A+B=0+1=1

If A =1 and B=0 then A+B=1+0=1

If A=1 and B=1 then A+B=1+1=1

**If A=0 and B=1 or A=1 and B=0 then A AND B=0 but A OR B=1**

**This is the main difference A AND B and A OR B.**

a) The **probability **that a new municipal bond **issued **by a city will receive an A rating is 0.625 or 62.5%.

b) 56% of municipal **bonds **are issued by cities.

c) The **proportion **of municipal bonds **issued **by **suburbs **is 0.325 or 32.5%.

Let's solve each part of the problem:

a. If a new **municipal **bond is to be issued by a city, what is the probability that it will receive an A rating?

Use **conditional **probability here.

Using conditional probability notation, we have:

P(A | City)

To calculate this, use the following **formula**:

P(A | City) = P(A and City) / P(City)

We are given:

- P(A) = 0.70 (**probability **of an A rating)

- P(B) = 0.20 (probability of a B rating)

- P(C) = 0.10 (probability of a C rating)

For **bonds **issued in cities:

- P(City | A) = 0.50 (probability that it's a city if it's rated A)

- P(City | B) = 0.60 (probability that it's a city if it's rated B)

- P(City | C) = 0.90 (probability that it's a city if it's rated C)

Now, let's calculate:

P(A and City) = P(A) * P(City | A)

P(City) = P(A) * P(City | A) + P(B) * P(City | B) + P(C) * P(City | C)

**Substitute **the values:

P(A and City) = 0.70 * 0.50

= 0.35

P(City) = (0.70 * 0.50) + (0.20 * 0.60) + (0.10 * 0.90)

= 0.35 + 0.12 + 0.09

= 0.56

Now, calculate the **conditional **probability:

P(A | City) = P(A and City) / P(City)

= 0.35 / 0.56

= 0.625

So, the **probability **is 0.625 or 62.5%.

b. What proportion of municipal bonds are issued by cities?

56% of municipal **bonds **are issued by cities.

c. What proportion of municipal bonds are issued by suburbs?

To find the proportion of municipal bonds issued by suburbs, use a similar approach:

P(**Suburb**) = P(A) * P(Suburb | A) + P(B) * P(Suburb | B) + P(C) * P(Suburb | C)

We are given:

- P(Suburb | A) = 0.40

- P(Suburb | B) = 0.20

- P(Suburb | C) = 0.05

Now, calculate:

P(Suburb) = (0.70 * 0.40) + (0.20 * 0.20) + (0.10 * 0.05)

= 0.28 + 0.04 + 0.005

= 0.325

So, the **proportion **of municipal bonds **issued **by **suburbs **is 0.325 or 32.5%.

The probability that a municipal bond issued by a city will receive an A rating is 35%. The proportion of all municipal bonds issued by cities is 56%. The proportion of all municipal bonds issued by suburbs is 32.5%.

This question requires an understanding of **probability** and conditional probability.

**a)** To find the probability that a new municipal bond issued by a city will receive an A rating, we must first determine the likelihood that an A-rated municipal bond is issued by a city. Given that 50% of A-rated bonds are issued by cities and that 70% of all bonds receive an A rating, we can calculate this probability as (0.50)*(0.70) = 0.35, or 35%.

**b)** To find the proportion of municipal bonds issued by cities, we must add up the bonds issued by cities across all ratings. So, (0.70*0.50) + (0.20*0.60) + (0.10*0.90) = 0.35 + 0.12 + 0.09 = 0.56, or 56%.

**c)** To calculate the** proportion **of municipal bonds issued by suburbs, we do the same calculation as in part b) but for suburbs. So, (0.70*0.40) + (0.20*0.20) + (0.10*0.05) = 0.28 + 0.04 + 0.005 = 0.325, or 32.5%.

b. y = sin x

c. y = sec x

d. y = cos x

The **function **is **even **will be y = sec x and y = cos x. Then the **correct **options are **C** and **D**.

**Even Function **- A true function f(x) is said to be an **even **function if the **output **value of f(-x) is the **same **as the f(x) for all **values **of x in the **domain **of f.

The **equation **should be **stored **in an **even **function:

f(-x) = f(x)

**Check **all that apply.

a. y = csc x, then **replace **x with -x. Then we have

y = csc -x

y = 1/sin -x

y = - 1/ sin x

y = -csc x

b. y = sin x, then **replace **x with -x. Then we have

y = sin -x

y = - sin x

c. y = sec x, then **replace **x with -x. Then we have

y = sec-x

y = 1/cos -x

y = 1/ cos x

y = sec x

d. y = cos x, then **replace **x with -x. Then we have

y = cos -x

y = cos x

Thus, the **function **is **even **will be y = sec x and y = cos x.

Then the **correct **options are **C** and **D**.

**Answer:**

0.11

**Step-by-step explanation:**

The events are independent, so:

P(A and B) = P(A) × P(B)

P = 0.5 × 0.22

P = 0.11
