Seema likes to grow bright flowers, so she buys 32 daffodil bulbs. She plants 12 bulbs in her front yard. Then Seema evenly divides the rest of the bulbs into 4 pots.

The ratio of the rainbow fish to guoramis to corydoras is 5:2:3

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other. For example, if there is 1 boy and 3 girls you could write the ratio as: 1 : 3 (for every one boy there are 3 girls) 1 / 4 are boys and 3 / 4 are girls.

Rainbow fish is half, this means that the percentage of rainbow fish is 100×1/2 = 50%

percentage of guoramis is 20%

therefore the percentage corydoras = 100-(20+50) = 30%

therefore the ratio of rainbow fish to guoramis to corydoras = 50:20:30

divide through by 10 = 5:2:3

PRE and POC.

Hence the equivalent side lengths are given as follows:

Then the proportional relationship among the equivalent side lengths is given as follows:

x/165 = (x + 125)/255.

Applying cross multiplication, the length PR, represented by x, is obtained as follows:

255x = 165(x + 125).

225x = 165x + 20625

60x = 20265

The bearing of the airport from the plane is calculated as; 245 degrees

The parameter given is that the bearing from the airport to the plane is 65 degrees.

From the the diagram I have attached, since the bearing from airport to plane is 65 degrees, we see that the bearing is calculated from North.

Thus, the 360° covering the North to the south in the clockwise direction is 180°

When the bearing required is from plane to bearing , the angle will be;

180 + 65 = 245 degrees

The probability of each team winning the tournament is A= 0,2 B= 0,2     C= 0,4 D=0,2

We know that only one team can win, so the sum of each probability of winning  is one

P(A)+P(B)+P(C)+P(D)=1

then we know that the probability of Team A and B are the same, so

P(A)=P(B)

And that the probability that either team A or team C wins the tournament is 0.6, so P(A)+Pc)= 0,6, then P(C)= 0.6-P(A)

Also, we know that team C is twice as likely to win the tournament as team D, so P(C)= 2 P(D) so P(D) = P(C)/2= (0.6-P(A))/2

Now if we use the first formula:

P(A)+P(B)+P(C)+P(D)=1

P(A)+P(A)+0.6-P(A)+(0.6-P(A))/2=1

0,5 P(A)+0.9=1

The number of permutations for the remaining hours is 6 hours.

Permutation is a mathematical concept that refers to the arrangement of objects or elements in a specific order. It is used to find the number of possible combinations of a given set of elements.

Let's assume that she takes exactly three hours of classes on Monday, two on Thursday, and one on Friday. Now, we have three hours left for Tuesday, Wednesday, and the rest of the week.

To find the number of permutations for the remaining hours, we can use the permutation formula, which is:

P(n, r) = n! / (n-r)!

Where n is the total number of items and r is the number of items being selected. In this case, n = 3 (hours left for Tuesday, Wednesday, and the rest of the week) and r = 3 (hours being selected).

So, the number of permutations for the remaining hours is:

P(3, 3) = 3! / (3-3)! = 6

Above 700: 5%, Above 550: 34%, Between 400 and 550: 26%, Below 400: 16%, Below 550: 55%.

To calculate the fraction of students who scored above 700, we can use the z-score formula, which is (x - μ) / σ, where x is the score, μ is the mean, and σ is the standard deviation. In this case, μ = 500 and σ = 100. Plugging in 700 for x, we get (700 - 500) / 100 = 2. This corresponds to a z-score of 2, which is .9772, meaning that 97.72% of the scores are below 700. This means that 5% are above 700. To calculate the fraction of students who scored above 550, we can use the same formula, but with 550 for x. This gives us (550 - 500) / 100 = .5, which corresponds to a z-score of .5, meaning that 84% of the scores are below 550. This means that 34% are above 550. To calculate the fraction of students who scored between 400 and 550, we can subtract the z-score of 400 from that of 550. This gives us .84 - .2 = .64, meaning that 64% of the scores are below 550.

To find the value of x, we need to solve the equation:

5x - (x + 3) = 3(2 - 2x) + x

Expanding the right-side expression:

5x - (x + 3) = 6 - 6x + x

Combining like terms on both sides:

6x - 3 = 6 - 5x

Adding 5x and 3 to both sides:

11x = 9

Dividing both sides by 11:

x = 9/11

So the value of x is approximately 0.818181818.

If they want to make a profit of $1,725 or more, then they need to sell at least 101 tickets.

We know that each ticket costs $25, then if they sell t tickets the revenue is:

R(t) = 25t

We know that the band has a cost of $800, and they want to make a profit of at least $1,725, then we can write the inequality below:

25t - 800 ≥ 1,725

(remember that the profit is the difference between the revenue and the cost).

Now we can solve that for t.

25t  ≥ 1,725 + 800

25t  ≥ 2,525

Probability is an area of mathematics that deals with numerical representations of how probable an event is to occur or how likely a statement is to be true. The probability of an occurrence is a number between 0 and 1, where 0 denotes the event's impossibility and 1 represents certainty. A probability is a number that represents the possibility or chance that a specific event will occur. Probabilities can be stated as proportions ranging from 0 to 1, as well as percentages ranging from 0% to 100%.
