a) The total number of possible outcomes is n = 16 outcomes

b) The probability of selecting an orange ball and a blue ball in either order is given by P = 2/9

The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible

Probability = number of desirable outcomes / total number of possible outcomes

The value of probability lies between 0 and 1

Given data ,

Let the probability of selecting an orange ball and a blue ball in either order be represented as P

Now , the value of P is

The total number of balls in the bag = 4 balls

The number of blue balls = 2

The number of yellow balls = 1

The number of orange balls = 1

The total number of outcomes S = { ( blue , blue ) , ( blue , orange ) , ( orange , blue ) , ( yellow , blue ) , ( blue , yellow ) , ( yellow , orange ) , ( orange , yellow ) , ( yellow , yellow ) , ( orange , orange ) }

Now , the sample space of selecting 2 balls that are orange and a blue ball is A = { ( orange , blue ) , ( blue , orange ) }

So , the probability of selecting an orange ball and a blue ball in either order is P = 2/9

Hence , the probability is 2/9

27. W = V/LH

28.  B = (A - PH)/2

In algebra, to solve for any variable, we have to make the variable the subject of the formula by isolating the variable to one side of the algebraic equation.

21. Let the unknown number = x. The algebraic equation that would be used to find x is:

x - 6 = -11

Solve for x

x = -11 + 6

x = -5

23. Let the unknown number = x. Thus, the algebraic equation to be created to find x would be:

5x - 1 = -11

Solve for x

5x = -11 + 1

5x = -10

x = -10/5

x = -2

Answer:

21:x=17

23:x=-2

24:35,37,39

27:V/LH

28:B=(A-PH)/2

Step-by-step explanation:

21: To find the difference between 6 and -11, you can do 6-(-11). Since the two negatives cancel out into positive, it will become 6+11 which is 17.

23: So we know that -11 is 1 added to 5 times a number. Let's just use x for the number. So we have 5x+(-1)=-11 or 5x -1=-11. So we move the negative 1 to the other side and make the sign in front of it a positive. It would look like this: 5x=-11+1, which is also 5x=-10, so x=10/5 or -2.

24: You first do 111/3 which is 37. Then on the left side, you take away to from 37 since it wants it to be odd, and on the right side, you add 2 to get 39. So, it will look like: 35,37,39.

27: V=LWH, W=V/LH.

28: A - PH = PH + 2B - PH, A - PH = 2B, (A - PH)/2 = 2B/2, B = (A - PH)/2.

In order to divide these numbers, first let's start with a 0 in the unit place, since 9.2 is smaller than 52.063.

Then, we multiply 9.2 by 10, this way we will calculate the tenths place.

Now, dividing 92 by 52.063, we have 1 as the result.

The remainder will be 92 - 52.063 = 39.937.

Again, let's multiply the remainder by 10, so now we will calculate the hundredths of the result.

Dividing 399.37 by 52.063 we have 7.

The remainder is 399.37 - 7*52.063 = 34.929.

Multiplying by 10, we have 349.29, and now we calculate the thousandths.

Dividing 349.29 by 52.063 we have 6.

Until now, the result of the division is 0.176.

Rounding to the nearest hundredth, we have 0.18 as the result of the division.

A) x = 0

B) x = 1 or 0

Part A; (7²)ˣ = 1

From Laws of indices, we know that any number raised to the power of 0 equals 1.

Thus; 7⁰ = 1

We now have;

(7²)ˣ = 7⁰

Opening the bracket, 2 will multiply x to give;

= 7⁰

Both powers will be equal because their base numbers are equal.

Thus; 2x = 0

x = 0

Part B;

= 1

Like in Part A, 7⁰ = 1

Thus;

1ˣ = 1⁰

Equating both powers; x = 0

Again, x could also be gotten from;

1ˣ = 1¹

x = 1

This is because 1¹ is still equal to 1.

x = 1 or 0

If the forces of 20 newtons upward and 20 newtons downward are equal in magnitude and opposite in direction, the object is in a state of equilibrium.

The state of the object can be described by considering the net force acting on it. The net force is the vector sum of all the individual forces acting on the object. In this case, we have a force of 20 newtons upward and a force of 20 newtons downward.

If the two forces are equal in magnitude and opposite in direction, they will cancel each other out and the net force will be zero. This means that the object is in a state of equilibrium, where the forces are balanced and there is no acceleration. In other words, the object is not moving and remains at rest.

Therefore, if the forces of 20 newtons upward and 20 newtons downward are equal in magnitude and opposite in direction, the object is in a state of equilibrium.

However, if the forces are not equal in magnitude or not opposite in direction, the net force will not be zero. In this case, the object will experience a resulting force in the direction of the greater force. The object will accelerate in that direction according to Newton's second law of motion (F = ma), where F is the net force and a is the acceleration of the object.

To summarize, if the forces of 20 newtons upward and 20 newtons downward are equal and opposite, the object is in a state of equilibrium. If they are not equal and opposite, the object will experience a resulting force and will accelerate in the direction of the greater force.

Answer:

number of Roses = 60

number of carnations = 80

number of Lilies = 75

Step-by-step explanation:

Roses = $3.00

carnations = $1.00

Lilies = $2.00

Total order = 215

Let

x = number of Roses

y = number of carnations

z = number of Lilies

There are 15 more lilies than roses.

z = x + 15

The total of the order came to $410.00.

x + y + z = 215

3x + y + 2z = 410

substitute z = x + 15

x + y + x + 15 = 215

3x + y + 2(x+15) = 410

2x + y + 15= 215

3x + y + 2x + 30 = 410

2x + y = 215 - 15

5x + y = 410 - 30

2x + y = 200 (1)

5x + y = 380 (2)

Subtract (1) from (2)

5x - 2x = 380 - 200

3x = 180

Divide both sides by 3

x = 180/3

= 60

x = 60

Recall

z = x + 15

z = 60 + 15

= 75

z = 75

Substitute the value of x into (1)

2x + y = 200

2(60) + y = 200

120 + y = 200

y = 200 - 120

= 80

y = 80

Therefore,

x = number of Roses = 60

y = number of carnations = 80

z = number of Lilies = 75

The curl of the vector field F =< 6ycos(x), 2xsin (y) >  is given by (2sin(y) - 6cos(x)).

To find the curl of the vector field F =< 6ycos(x), 2xsin(y)>, we can use the formula for the curl of a vector field in two dimensions, which is given by:

curl(F) = (∂Q/∂x - ∂P/∂y)

In this case, we have P(x,y) = 6ycos(x) and Q(x,y) = 2xsin(y), so we need to compute the partial derivatives of these functions with respect to x and y.

∂P/∂y = 6cos(x)

∂Q/∂x = 2sin(y)

The margin of error can be calculated using the formula:
Margin of error = (upper limit of the confidence interval - lower limit of the confidence interval) / 2

In this case, a margin of error of 9.55 suggests that the sample mean is quite precise, since it's relatively close to the true population mean (which we know to be 52.90).

In this case, the lower limit of the confidence interval is 43.85 and the upper limit is 61.95.
Margin of error = (61.95 - 43.85) / 2
Margin of error = 9.55
Therefore, the margin of error is 9.55. This means that if the sample size were to be repeated, we would expect the sample mean to be within 9.55 units of the true population mean 95% of the time.
It's worth noting that the confidence interval provides a range of values within which we can be reasonably certain that the true population mean lies. The margin of error, on the other hand, gives us an indication of the precision of our estimate. However, if the margin of error were larger, this would indicate that our estimate is less precise and that we need a larger sample size to obtain a more accurate estimate of the population mean.

Answer: d) v = 3.20 + 1.50n.

Step-by-step explanation:

Let 'v' be the price to pay in a 'n' kilometer.

Given: The price to be paid for a taxi ride includes a fixed parcel, called a flag, and a parcel that depends on the distance traveled.

Flag costs = $ 3.20 and

Each kilometre run costs = $ 1.50

Then, the amount of 'v' to pay in a 'n' kilometer race = Flag costs +   (n)× (Each kilometre run costs )

⇒ v= 3.20 + 1.50n

Hence, the correct option is  d) v = 3.20 + 1.50n.

The diver collected water samples at every 3 meters, starting from 5 meters below the water surface, up to a final depth of 35 meters.

We can find the number of samples collected by dividing the total depth range by the distance between each sample and then adding 1 to include the first sample.

The total depth range is:

35 m - 5 m = 30 m

The distance between each sample is 3 m, so the number of samples is:

(30 m) / (3 m/sample) + 1 = 10 + 1 = 11

Therefore, the diver collected a total of 11 water samples.

Taking into account definition of probability, the probability of those who like both is 0.07 or 7%.

Probability is the greater or lesser possibility that a certain event will occur.

In other words, the probability is the possibility that a phenomenon or an event will happen, given certain circumstances. It is expressed as a percentage.

The union of events, AUB, is the event formed by all the elements of A and B. That is, the event AUB is verified when one of the two, A or B, or both occurs. AUB is read as "A or B".

The probability of the union of two compatible events is calculated as the sum of their probabilities subtracting the probability of their intersection:

P(A∪B)= P(A) + P(B) -P(A∩B)

where the intersection of events, A∩B, is the event formed by all the elements that are, at the same time, from A and B. That is, the event A∩B is verified when A and B occur simultaneously.

A complementary event, also called an opposite event, is made up of the inverse of the results of another event. That is, That is, given an event A, a complementary event is verified as long as the event A is not verified.

The probability of occurrence of the complementary event A' will be 1 minus the probability of occurrence of A:

P(A´)= 1- P(A)

In first place, let's define the following events:

Then you know:

In this case, considering the definition of union of events, the probability that a chef likes carrots and broccoli is calculated from:

P(C∪B)= P(C) + P(B) -P(C∩B)

Then, the probability that a chef likes carrots and broccoli is calculated as:

P(C∩B)= P(C) + P(B) -P(C∪B)

In this case, considering the definition of the complementary event and its probability, the probability that a chef likes NEITHER of carrots and broccoli is calculated as:

P [(C∪B)']= 1- P(C∪B)

In this case, the probability of those who like neither is 0.22

0.22= 1 - P(C∪B)

Solving

0.22 - 1= - P(C∪B)

-0.78= - P(C∪B)

- (-0.78)= P(C∪B)

0.78= P(C∪B)

Now, remembering that P(C∩B)= P(C) + P(B) -P(C∪B), you get:

P(C∩B)= 0.13 + 0.72 -0.78

Solving:

P(C∩B)= 0.07=  7%

The diameter of circle C is \(x\), which is \(5\).

A circle is the collection of all points on a plane that are at a specified distance from another point (the radius) (the centre). A radius is any distance separating a point on a circle from its center. Any two radii are equal in length under the concept of a circle.

A semicircle is a half circle produced by splitting a circle into two equal parts. It is created when a line pierces the circle's center and touches its two ends.

Since \(CE\) is a radius of the circle and the diameter is \(30\) units long, we know that \(CE\)is half the length of the diameter:

\(CE = 1/2\)(diameter)\(= 1/2(\)30 units)\(= 15\) units

We are given that \(CE = 6x\), so we can solve for \(x\):

\(CE = 6x = 15\)

\(x = 15/6\)

\(x = 2.5\)

Now, we can use the fact that angle \(CED\), where \(D\) is the center of the circle, is a central angle that intercepts arc \(CD\), to find the measure of angle \(CED\).

Since the diameter of the circle is a straight line, it forms a \(180\) degree angle at its endpoints. Therefore, angle \(CED\) is half of this angle, which is:

angle \(CED = 1/2(180 degrees) = 90\)degrees

We are given that angle \(CED\) is \(30\) degrees, so we can set up an equation:

angle \(CED = 30 = 6x\)

Simplifying and solving for \(x\):

\(6x = 30\)

\(x = 30/6\)

\(x = 5\)

Therefore, \(x\) is equal to \(5\).
