From the statement, we know that there are two possible scenarios:

A) Kira rolls the die and gets a face with a 1, 2, 3, 4, 5 or 6.

• The probability of this event is P(A) = 1/12.

• Kira will write the number of the face in this case.

B) Kira rolls the die and gets an edge.

• The probability for this event is 1/24.

• Kira will write the sum of the numbers that share the top edge.

• There are multiple values for the result of the sum.

We must take into account that:

• 1 and 5 are on opposite faces,

• 2 and 3 are on opposite faces,

• 4 and 6 are on opposite faces.

The possible values of the sum and the forms to get it are:

0. 3, = 1 + 2 → P(B'_1) = 1/24

1. 4, = 1 + 3 → P(B'_2) = 1/24

2. 5, = 1 + 4 → P(B'_3) = 2/24

3. 6, = 2 + 4 → P(B'_4) = 2/24

4. 7, = 1 + 6 = 2 + 5 = 3 + 4 → P(B'_5) = 3/24

5. 8, = 2 + 6 = 3 + 5 → P(B'_6) = 2/24

6. 9, = 3 + 6 = 4 + 5 → P(B'_7) = 2/24

7. 11, = 5 + 6 → P(B'_9) = 1/24

We have 8 possible results for the sum.

---------------------

Now, we want to know the value of the expected value of the numbers recorded by Kira.

By definition, the expected value is calculated by multiplying each of the possible outcomes by the likelihood that each outcome will occur and then summing all of those values.

The expected value of the number recorded by Kira will be:

Where:

• A_i represents the result of event A_i and P(A_i) its probability,

• B_i represents the result of event B_i and P(B_i) its probability.

Using the data from above, we compute each of the sums.

A) For the first sum, we take into account that each event A_i has the same probability:

B) For the second sum, we use each of the values of the sum and the probabilities of each sum:

Summing the results of each sum, we get the following result for the expected value:

The expected value for the number recorded is 137/24 or approximately 5.71.

(a) Amount of water in the first pool (In liters) = (817 + 19x) liters

Amount of water in the second pool (in liters) = 39x liters

(b) An equation to show when the two pools would have the same amount of water is 817 + 19x = 38x.

Given:

For the First Pool :

Initial amount of water in the Pool = 817 liters

Water is being added to the first pool at a rate of 19 liters per minute.

Amount of water added after x minutes = 19x

So, Total amount of water after x minutes = (817 + 19x) liters

For the Second Pool:

It was empty initially.

Water is being added to the second pool at a rate of 38 liters per minute.

Amount of water added after x minutes = 38x

So, Total amount of water after x minutes = 38x liters

Now to determine an equation to show when the two pools would have the same amount of water.

817 + 19x = 38x

38x - 19x = 817

The water pressure on a submerged object is given by P = 64d, then the value d is 10.5 feet.

a. D = P/64 is the solution to the formula's "d" subject.

b. The depth of a submerged object at a pressure of 672 pounds per square foot is 10. 5 feet.

A function can be defined as an expression, law or rule that shows the relationship between two variables.

Given the role as;

P = 64d

Where;

P stands for pressure in pounds per square foot.

The object's depth, d, is expressed in feet.

Now let's center the formula on the variable "d."

Both sides of the equation are divided by the variable "d64-based "'s coefficient. This is carried out so that the variable can stand on its own.

We have.

P/64 = 64d/64

d = P/ 64

If there is pressure, P is equivalent to 672 pounds per square foot.

When the value of the variable is inserted into the formula, we obtain;

d = P/64

Then,

d = 672/64

Discover the quotient.

d = 10. 5 ft.

Therefore,

The water pressure on a submerged object is given by P = 64d, then the value d is 10.5 feet.

The value of composite function (f о g) (-1) will be -1.

What is Composite function?

A composite function is a function that is written inside with another function and composition of functions is done by substituting one function into another function.

Given that;

The value of functions are;

f (x) = - 3x -1

And, g (x) = x² - 1

Now, All values of functions are;

f (x) = - 3x -1

And, g (x) = x² - 1

Composition of functions is calculated as;

Since, (f о g) (x) = f (g(x))

Substitute the value of function f(x) and g(x) in above equation;

(f о g) (x) = f (g(x))

              = f (x² - 1)

              = - 3(x² - 1) - 1

              = -3x² + 3 - 1

              = -3x² + 2

Put x = -1 in above equation we get;

(f о g) (-1) = - 3 (-1)² + 2

              = - 3 + 2

              = -1

So,  (f о g) (-1) = -1

Figure out how many times 8 can fit into 24.(That would be 3 times) Then multiply 3 by the number of times 8 fit into 24 and get to your answer! (Please let me know if I am wrong)

Answer:

[C] 9

Step-by-step explanation:

Given:

Roland has a basket of 24 fruits. If 3 out of 8 of these fruits are oranges, how many oranges are in Roland's basket?

Solve:

" 3 out of 8 " is the same things as "⅜"

Therefore,

24 × ⅜

Now solving 24 × ⅜:

24 is the same as 24/1 since 24 divided by 1 is 24.

Hence, the problem will be like this:

[tex]\frac{24}{1}\times\frac{3}{8}[/tex]

Multiply the numerators together (24 x 3 = 72) and multiply the denominators together (1 x 8 = 8) and make it into one fraction like so:

[tex]\frac{72}{8}[/tex]

Now we have to find the GCF: GCF = Greatest Common Factor;

The greatest common factor of 72 and 8 is 8.

Dividing the numerator and the denominator by its greatest common factor to get:

[tex]\frac{9}{1}[/tex]

Convert the improper fraction above to a whole number to get the answer:

Okay, here we have this:

Considering the provided information, we are going to find the x- and y- intercepts and explain its meaning. So we obtain the following:

Since the x-intercept is the point where the Graph intersects the x-axis (y=0) and the y-intercept is the point where the Graph intersects the y-axis (x=0), we have that:

x-intercept=(300, 0)

y-intercept=(0, 16)

Since the y-axis represents the number of gallons, and the x-axis time, then the y-intercept indicates that when filling the tank it was left with 16 gallons, and the x-intercept indicates that when emptying the tank had traveled 300 miles.

The size of the shift from function f to function g is 12 units down

The table of values is given as

g(x) -11 -10 -8 -4 4

From the question, we understand that the function g(x) is an exponential function

The parent function of an exponential function in this case, is represented as

f(x) = 2^x

When represented on a table of values, we have

x 0 1 2 3 4

f(x) 1 2 4 8 16

So, we have

x 0 1 2 3 4

f(x) 1 2 4 8 16

g(x) -11 -10 -8 -4 4

Notice that the difference between the values of f(x) and g(x) is 12

This means that

g(x) = f(x) - 12

So, we have

g(x) = 2^x - 12

Hence, the size of the shift is 12 units down

Answer: x=10

Step-by-step explanation:

1/5(x-2)=1/10(x+6)

Distribute and multiply first

(1/5*x) -(1/5*2)=(1/10*x) +(1/10*6)

1/5x-2/5=1/10x+6/10

We do not have the same denominators on both sides. 5 goes into 10 two times so we will multiply everything on the left by 2 to get a common denominator.

2/10x-4/10=1/10x+6/10

Subtract 1/10x from both sides

1/10x-4/10=6/10

Add 4/10 to both sides

1/10x=10/10

1/10x= 1

Multiply both sides by 10/1 (the fraction inverse) to get rid of the fraction.

(10/1)(1/10x) =(1)(10/1)

In this problem we find a line segment whose endpoints are known and we need to determine the equation of the line perpendicular such that the segment is partitioned into two segments of equal length. Now we present the procedure. First, determine the coordinates of the midpoint:

M(x, y) = 0.5 · (8, - 1) + 0.5 · (4, - 9)

M(x, y) = (6, - 5)

Second, determine the slope of the line segment:

m = [- 9 - (- 1)] / (4 - 8)

m = (- 8) / (- 4)

m = 2

Third, calculate the slope of the bisector:

m' = - 1 / m

m' = - 1 / 2

Fourth, determine the intercept of the bisector:

b = y - m' · x

b = - 5 - (- 1 / 2) · 6

b = - 5 + 3
