Question

Farmer Jim keeps 12 hens in every cooper if farmer Jim has 20 coops

a) how many hens does she have ?

b) if every hens lays 9 eggs on Monday how many eggs will farmer Jim collect on Monday

Answer:

a) 240 hens

b) 2160 eggs

Step-by-step explanation:

a) Farmer Jim keeps 12 hens in every cooper if farmer Jim has 20 coops

Hence,

1 coop = 12 hens

20 coops = y hens

Cross Multiply

y hens = 20 coops × 12 hens/1 coop

y hens = 240 hens

Therefore Farmer Jim has 240 hens

b) We are told in question b that: if every hens lays 9 eggs on Monday how many eggs will farmer Jim collect on Monday?

From question a) we determine that the number of hens that Farmer Jim has:

240 hens

Hence,

1 hen = 9 eggs

240 hens = z eggs

z eggs = 240 hens × 9 eggs/1 hen

z eggs = 2160 eggs

Therefore, on Monday Farmer Jim will collect 2160 eggs

It is not possible to provide a complete answer without the specific values of the length, width, and height of each prism. However, in general, the prism with the greatest volume is typically the one with the largest dimensions.

This is because volume is calculated by multiplying the length, width, and height together, so a prism with larger dimensions will have a greater volume than one with smaller dimensions.

As for the prism with the smallest volume, this would likely be the one with the smallest dimensions. Again, without the specific values, it is difficult to determine which prism has the smallest volume.

In order to predict which prism will have the greatest volume, one would need to know the dimensions of each prism. By comparing the dimensions of each prism, one can determine which one has the greatest volume. The prism with the largest dimensions will have the greatest volume, as volume is directly proportional to the dimensions of the prism.

The angle x in the circle is 12 degrees.

The angles at the circumference subtended by the same arc are equal. In other words, the angles at the circumference subtended by the same arc are congruent.

Therefore,

3x = 36°

divide both sides of the equation by 3

x = 36 / 3

x = 12

Therefore,

x = 12 degrees

Based on probability calculations, approximately 7% of the people in the large group should obtain counts in the range of 20 to 30 aces when rolling a die 150 times.

When rolling a fair six-sided die, the probability of getting an ace (a single dot) is 1/6. Therefore, the probability of not getting an ace in a single roll is 5/6. To calculate the probability of obtaining a specific number of aces in 150 rolls, we can use the binomial distribution. In this case, the number of trials is 150, and the probability of success (getting an ace) in each trial is 1/6.

Using statistical calculations, we can determine the probability of obtaining counts between 20 and 30 aces. This involves summing the probabilities of getting 20, 21, 22, ..., 30 aces individually. This range of counts corresponds to a relatively small portion of the entire distribution. By calculating these probabilities and summing them, we find that the percentage of people who should obtain counts in the range 20 to 30 is approximately 7% of the total group size.

It's important to note that these calculations assume a fair six-sided die and independent rolls. The actual outcomes may vary due to chance, but on average, about 7% of the individuals in the large group would be expected to have counts in the specified range.

Answer:

problem 2

Step-by-step explanation:

The feeding time constraint for cats can be written symbolically as:

12 minutes/day * number of cats <= 8 hours/day

The feeding time constraint for dogs can be written symbolically as:

20 minutes/day * number of dogs <= 8 hours/day

The pampering time constraint for cats can be written symbolically as:

16 minutes/day * number of cats <= 8 hours/day

The pampering time constraint for dogs can be written symbolically as:

20 minutes/day * number of dogs <= 8 hours/day

Thus, the value of f6 using a 3-day weighted moving average with w1 is 60.

To calculate the 3-day weighted moving average with w1 for the value of f6, we need to first calculate the weighted average for the past three days.

The formula for weighted moving average is:

WMAt = [(P1 * w1) + (P2 * w2) + (P3 * w3)] / (w1 + w2 + w3)

where:
- WMAt is the weighted moving average for time t
- P1, P2, P3 are the values of the variable for the three time periods being averaged
- w1, w2, w3 are the weights assigned to each period (in this case, w1 = 1 and w2 = w3 = 0)

For the past three days, we have:

- Day 4: 60 rolls sold
- Day 5: 53 rolls sold
- Day 6: 60 rolls sold

Using the formula above with w1 = 1 and w2 = w3 = 0, we get:

WMA6 = [(60 * 1) + (53 * 0) + (60 * 0)] / (1 + 0 + 0) = 60

Therefore, the value of f6 using a 3-day weighted moving average with w1 is 60.

Answer:

A. 140

Step-by-step explanation:

The angle symbol on angles 1 and 2 indicates they are equal. Since angle 2 is 40 degrees, angle 1 is as well. Angles 1 and 4 are also equal because they are vertical angles. Angle 1+Angle 4 is 40+40=80. The sum of all of the angles is 360. 360-80=280. Since angles 3 and 5 are also vertical angles, 280/2=140. Therefore angle 5 is 140 degrees.

Answer:

54

Step-by-step explanation:

We'll call the number "ab".

From left to right, the value of this number will be \(10a+b\).

From right to left, the value of this number will ve \(10b+a\).

From the question,

\(10a+b=1.2(a+10b)\\10a+b=1.2a+12b\\8.8a=11b\)

For a and b to be whole numbers,

\(\left \{ {{a=5} \atop {b=4}} \right.\)

So the number is 54.

The value of the yakubu and bello business is N80,000.

Let's start by determining the original value of Yakubu and Bello's shares in the business before the sale took place.

The ratio of their shares is given as 3:5, which means Yakubu owns 3 parts and Bello owns 5 parts out of a total of 3+5 = 8 parts.

Now, let's assume the value of the business is represented by "V" (to be determined).

Since Yakubu later sold 3/4 of his share to Bello, this means he sold 3/4 * 3 = 9/4 parts of the business to Bello.

The value of 9/4 parts of the business is N180,000, so we can set up the following equation:

(9/4) * V = N180,000

To solve for V, we multiply both sides of the equation by 4/9:

V = (4/9) * N180,000

V = N80,000

Therefore, the value of the business is N80,000.

None of these sets are equal to one another.

Set A is given as {6, 8, 10, 14}. This is a listing of specific numbers in ascending order.

Set B is defined as {x | x is an even number from 6 through 14}. In this set, the elements are described using a rule or condition. The set includes all even numbers between 6 and 14, inclusive.

Set C is defined as {x | x is a number from 6 through 14 and is divisible by 2}. Similar to set B, set C also uses a rule or condition to describe its elements. The set includes all numbers between 6 and 14 that are divisible by 2, i.e., all even numbers between 6 and 14.

Now, let's analyze the equality of the sets:

Set A contains the specific elements {6, 8, 10, 14}.

Set B contains the even numbers from 6 through 14, which are {6, 8, 10, 12, 14}.

Set C also contains the even numbers from 6 through 14, which are {6, 8, 10, 12, 14}.

Comparing the sets, we can see that Sets B and C have the same elements, {6, 8, 10, 12, 14}. Therefore, Sets B and C are equal.

However, Set A only contains the elements {6, 8, 10, 14}, which is not the same as the elements in Sets B and C. Therefore, Set A is not equal to Sets B and C.

In summary:

- Sets A and B are not equal.

- Sets A and C are not equal.

- Sets B and C are equal.

The picture presented is relevant to corresponding angles because it exemplifies what a corresponding angle is.

To have a corresponding angle the first condition is to have two or more parallel lines. Parallel lines are those that are equidistant. Now, if these two or more parallel lines are crossed by another line, an angle will be created in each line and because the lines are parallel the angle will be the same for the liens involved.
