The shaded area is 157.1 square cm

From the question, we have the following parameters that can be used in our computation:

Diameter = 10 cm

So, the area of the small semicircles is

Area = 1/2π(d/2)²

This gives

Area = 1/2π(10/2)²

Evaluate

Area = 25/2π

For the big semicircle, we have

Area = 1/2π(D/2)²

Area = 1/2π(20/2)²

So, we have

Area = 50π

i.e.

Area =50 * 3.142 = 157.1

The probability of ordering meat is 0.7 and the probability of ordering fish is 0.3.

P(+ | M) = 0.8 and P(- | M) = 0.2,

P(+ | F) = 0.95 and   P(- | F)  = 0.05.

P(M and +) = 0.56 and P(M and -) = 0.14,

P(F and +) = 0.285 and P(F and -) = 0.015.

C: the probability that the customer ordered fish is 0.3.

Probability is a way to gauge how likely something is to happen. According to the probability formula, the likelihood that an event will occur is equal to the proportion of positive outcomes to all outcomes. The probability that an event will occur P(E) is equal to the ratio of favorable outcomes to total outcomes.

Given The Humber, Room advertises two types of entrée, meat and fish,

70% of all customers order meat, and 30% order fish,

M represents the event of ordering meat, F is the event of ordering fish,

probability of M and F,

p(M) = 70% = 0.7

p(F) = 30% = 0.3

and 80% of those who ordered meat and 95% of those who ordered fish were satisfied,

+ is the event of being satisfied, and − is the event of not being satisfied,

probability of satisfied customers with meat,

p(+) = 80% = 0.8

not satisfied with meat,

p(-) = 1 - 0.8 = 0.2

probability of satisfied customers with fish,

p(+) = 95% = 0.95

not satisfied with fish,

p(-) = 1 - 0.95 = 0.05

B: calculating the joint probabilities,

P (M and +) = P(M ∩ +) = p(M)*p(+)

P (M and +) = 0.7*0.8

P (M and +) = 0.56

P (M and -) = P(M ∩ -) = p(M)*p(-)

P (M and -) = 0.7*0.2 = 0.14

P (F and +) = P(F ∩ +) = p(F)*p(+)

P (F and +) = 0.3*0.95

P (F and +) = 0.285

P (F and -) = P(F ∩ -) = p(F)*p(-)

P (F and -) = 0.3*0.05

P (F and -) = 0.015

C:  Determine the conditional probabilities,

P (+ | M) = P(M ∩ +)/p(M)

substitute the values

P (+ | M) = 0.56/0.7

P (+ | M) = 0.8

P (- | M) = P(M ∩ -) /p(M)

P (- | M) = 0.14/0.7

P (- | M) = 0.2

P (+ | F) = P(F ∩ +)/p(F)

substitute the values

P (+ | F) = 0.285/0.3

P (+ | F) = 0.95

P(- | F) = P(F ∩ -)/p(F)

P(- | F) = 0.015/0.3

P(- | F)  = 0.05

D: If a randomly selected customer was satisfied with his/her meal, what is the probability that the customer ordered fish,

to find P (F | +) = P(F ∩ +)/p(+)

Step 1: Setup

Set up your multiplication problem like this:

             9 3

     x       2 6

Step 2: Multiply

3 x 6 = 18. Put 8 below the line and 1 as a reminder on top:

             1  

             9 3

     x       2 6

               8

Step 3: Multiply

6 x 9 = 54. Take 54 and add 1 from the previous step to get 55. Enter 55 at the bottom:

             9 3

     x       2 6

           5 5 8

Step 4: Add 0

Enter a 0 at the bottom right as a place holder, because you now move over one digit:

             9 3

     x       2 6

           5 5 8

     +         0

Step 5: Multiply

2 x 3 = 6. Put 6 below the line and 0 as a reminder on top:

             0  

             9 3

     x       2 6

           5 5 8

     +       6 0

Step 6: Multiply

2 x 9 = 18. Take 18 and add 0 from the previous step to get 18. Enter 18 at the bottom:

             9 3

     x       2 6

           5 5 8

     +   1 8 6 0

Step 7: Add to get an answer

Add up the bottom two numbers (558 + 1860 = 2418) to get the answer:

             9 3

     x       2 6

           5 5 8

     +   1 8 6 0

     =   2 4 1 8

The bottom line is the answer. Therefore, 93 times 26 equals:

Answer: [tex]230[/tex]

Step-by-step explanation:

To find coterminal angles, add/subtract integer multiples of [tex]360^{\circ}[/tex].

[tex]-490^{\circ}+360^{\circ}=-130^{\circ}\\\\-130^{\circ}+360^{\circ}=230^{\circ}[/tex]

An angle θ that is coterminal with −490∘ and lies between 0∘ and 360∘ is 130∘.

To find an angle θ that is coterminal with −490∘ and lies between 0∘ and 360∘, we can use the concept of coterminal angles.

Coterminal angles are angles that have the same initial and terminal sides when drawn in standard position. To find a positive coterminal angle with a negative angle, we can add 360 degrees to the negative angle until we get an angle within the desired range (0∘ to 360∘).

Let's find the positive coterminal angle:

θ = -490∘ + 360∘

θ = -130∘

So, an angle θ that is coterminal with −490∘ and lies between 0∘ and 360∘ is 130∘.

Answer: Let's call the number of gallons of regular gas sold "x". Then, the number of gallons of premium gas sold would be 300 - x.

The total revenue from regular gas would be 2.15 * x dollars. The total revenue from premium gas would be 2.90 * (300 - x) dollars.

We know that the total receipts for the day were $690, so we can set up the following equation:

2.15x + 2.90(300 - x) = 690

Expanding the second term, we get:

2.15x + 870 - 2.90x = 690

Combining like terms, we get:

0.25x = -180

Dividing both sides by 0.25, we get:

x = 720

So, 720 gallons of regular gas and 300 - 720 = -420 gallons of premium gas were sold. However, since it is not possible to sell a negative number of gallons of gas, this solution is not valid.

If we try another value of x that is less than 300, we will find a valid solution. Let's try x = 200:

2.15 * 200 + 2.90 * (300 - 200) = 690

Expanding and simplifying, we get:

430 + 90 = 520

So, 200 gallons of regular gas and 300 - 200 = 100 gallons of premium gas were sold.

The length of side p of the triangle rounded to the nearest tenth is 7.5.

The cosine rule relates the lengths of the sides of a triangle to the cosine of one of its angles.

It is expressed as;

p = √( n² + m² - ( 2nm × cosθ ) )

Given the figure in the diagram;

Plug the values into the above formula and simplify.

p = √( n² + m² - ( 2nm × cosθ ) )

p = √( (11)² + (13)² - ( 2 × 11 × 13 × cos( 35 ) ) )

p = √( 121 + 169 - ( 286 × cos( 35 ) ) )

p = √( 290 - ( 286 × cos( 35 ) ) )

p = √( 290 - 234.27748  )

p = √( 290 - 234.27748  )

p = √55.72252
