The percent increase in the annual student fees at the University of California between 2000 and 2014 is 125%.

What is percentage?

Percentage is a way of expressing a number or proportion as a fraction of 100. It is represented by the symbol "%".

To find the percent increase, we need to calculate the difference between the two amounts and then divide that difference by the original amount, and finally multiply by 100 to express the result as a percentage.

The difference between the final amount ($9,000) and the initial amount ($4,000) is $5,000.

So the percent increase can be calculated as follows:

Percent increase = (difference / original amount) x 100%

= ($5,000 / $4,000) x 100%

= 125%

Therefore, the percent increase in the annual student fees at the University of California between 2000 and 2014 is 125%.

To determine the weight of the soccer balls the coach bought, we need

to analyze the given line plot. The line plot shows the weight of each of

the 11 soccer balls bought by the coach.

The first step is to find the scale of the line plot. In this case, the scale is

in pounds, and the plot ranges from 0 to 8 pounds. Each "x" on the plot

represents one soccer ball, and the height of the "x" shows the weight of

that ball in pounds.

To find the total weight of the soccer balls bought by the coach, we

simply need to add up the weights of all the balls. Looking at the line

plot, we can see that there are:

2 balls that weigh 1 pound each

1 ball that weighs 3 pounds

1 ball that weighs 2 pounds

1 ball that weighs 5 pounds

1 ball that weighs 3.7 pounds

1 ball that weighs 8 pounds

2 balls that weigh 4 pounds each

The effect of the Rule of 78s when a borrower repays an add-on method loan early may result in higher interest charges and potential prepayment penalties due to the uneven allocation of interest throughout the loan term.

The Rule of 78s is a method used by some lenders to allocate interest charges in add-on method loans, particularly for consumer loans. When a borrower repays an add-on method loan early, the Rule of 78s may affect how the prepayment is handled and the amount of interest charged.

Under the add-on method, the interest is calculated upfront based on the original loan amount and term. With the Rule of 78s, the interest is allocated to the loan payments in a manner that assigns more interest to the earlier payments in the loan term. This means that during the initial period of the loan, the borrower is primarily paying off interest rather than the principal.

When a borrower repays an add-on method loan early, the Rule of 78s may result in a higher amount of interest being charged compared to a simple interest loan. As the early payments have been disproportionately allocated more interest, the borrower may have paid off less of the principal than they would have under a simple interest method. Consequently, the borrower may face a higher prepayment penalty as they have not paid as much towards the principal balance as anticipated.

Answer:

Step-by-step explanation:

Fractions represent a division problem where the numerator is divided by the denominator. For example, the fraction 3/4 represents the division of 3 by 4, which can be written as 3 ÷ 4. This is why it makes sense that fractions are about division.

Furthermore, fractions are used to represent parts of a whole or a group. When we divide a whole into equal parts, we are essentially dividing the whole into groups, with each group having the same size. For example, if we divide a pizza into 8 equal slices, each slice represents 1/8th of the pizza. We can also think of this as dividing the pizza into 8 equal groups, with each group having one slice.

Therefore, fractions are a natural way to represent division, as they allow us to express how many parts we have out of a whole or a group, and how big each part is relative to the whole or group.

The total number of revolutions per minute tire makes when the car is traveling at a speed of 90 mi/hr and the tire has a diameter of 22 inches is equal to approximately 1375.09.

Diameter of a car tire = 22 inches

Speed of a car = 90mi/hr

Let us first convert the speed from miles per hour to inches per minute,

Since the diameter of the tire is given in inches.

90 mi/hr

= 90 × 5280 ft/hr

= 475200 ft/hr

= 475200 × 12 in/hr

= 5,702,400 in/hr

= 95,040 in/min

Number of revolutions the tire makes per minute,

Distance the tire travels in one revolution.

The circumference of a circle is given by,

C = πd

where C is the circumference and d is the diameter.

So the distance the tire travels in one revolution is,

d = π(22 in)

  = 69.115 in

Now, the number of revolutions per minute  is ,

=distance traveled per minute / distance traveled in one revolution

⇒ revolutions per minute = 95,040 in/min / 69.115 in/rev

⇒revolutions per minute ≈ 1375.09 rev/min

Therefore, the tire makes approximately 1375.09 revolutions per minute with tire of diameter of 22 inches.

To find the smallest total number of hot dogs that Yadira's mom can purchase, we need to find the least common multiple (LCM) of 12 and 9, since she wants the same number of hot dogs as hot dog buns.

The multiples of 12 are: 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, ...

The multiples of 9 are: 9, 18, 27, 36, 45, 54, 63, 72, 81, 90, ...

The least common multiple of 12 and 9 is 36, since it is the smallest number that appears in both lists. Therefore, Yadira's mom should purchase 36 hot dogs (3 packs of 12) and 36 hot dog buns (4 packs of 9) for the family barbecue.

If the test is normally distributed, then the probability of a score greater than 115 is (a) 1.62%.

In order to find probability of a score greater than 115 in a normally distributed test with a mean of 100 and standard deviation of 7,

First, We have to calculate z-score for 115, and

The z-score formula is ⇒ z = (x - μ)/σ,

where x = score of interest, μ = mean, and σ = standard-deviation.

In this case, we have x = 115, μ = 100, and σ = 7.

The z-score for 115 is ⇒ z = (115 - 100)/7 = 2.14

By using the normal table :

⇒ P(Z > 2.14) = 0.0162

Therefore, the required probability is 0.0162 or 1.62%, the correct option is (a) 1.62%.

There are 56,148 triangles that can be formed by drawing non-intersecting segments among the 34 points in the square.

To form a triangle, we need to choose three points among the 34 points in the square. There are 34C3 = 5984 ways to do this.

However, not all combinations of three points will form a triangle. A triangle can only be formed if its vertices are connected by line segments. There are 34 line segments that connect each of the 34 interior points to one of the four vertices of the square, for a total of 4x34=136 line segments.

Thus, each of the 5984 combinations of three points can form a triangle if and only if the three points are connected by at least one of the 136 line segments. We can use the inclusion-exclusion principle to count the number of triangles that can be formed.

Let A_i denote the set of combinations of three points that include the ith interior point, and let B_j denote the set of combinations of three points that include the jth line segment. Then, the number of triangles that can be formed is

|A_1 ∪ A_2 ∪ A_3 ∪ A_4 ∪ B_1 ∪ B_2 ∪ ... ∪ B_136|,

where |S| denotes the cardinality of set S.

By the inclusion-exclusion principle, this is:

|A_1| + |A_2| + |A_3| + |A_4| + |B_1| + |B_2| + ... + |B_136|

|A_1 ∩ A_2| - |A_1 ∩ A_3| - ... - |A_3 ∩ A_4| - |B_1 ∩ B_2| - ... - |B_135 ∩ B_136|

|A_1 ∩ A_2 ∩ A_3| + |A_1 ∩ A_2 ∩ A_4| + ... + |A_2 ∩ A_3 ∩ A_4| + ... + |B_1 ∩ B_2 ∩ B_3| + ... + |B_134 ∩ B_135 ∩ B_136|

|A_1 ∩ A_2 ∩ A_3 ∩ A_4| - ... - |B_1 ∩ B_2 ∩ ... ∩ B_136|.

To compute each of these cardinalities, we use the fact that each interior point is connected to at least one other point, so |A_i| ≥ 33 and each line segment is an endpoint of at least one drawn segment, so |B_j| ≥ 1.

Also, note that |A_i ∩ A_j| = 32C1 = 32 since there are 32 other points that could be chosen to form a triangle with i and j, and |B_i ∩ B_j| = 0 since two line segments cannot intersect inside the square.

Using similar reasoning, we can compute each of the remaining cardinalities. After doing so, we obtain:

33 x 34C2 + 136 x 33 - 32C2 x 6 - 32C2 x 3 + 32C3 x 4

= 56148.

 h - 130 = 75 demonstrates that h = 205 is a legitimate solution to the equation of height of hot air balloon.

We must discover the solution to the equation h - 130 = 75 for h, where h is the height of the balloon in feet, in order to determine its height before it started to descend.

We can increase both sides of the equation by 130 to isolate h:

h - 130 + 130 = 75 + 130

Simplifying:

h = 205

As a result, the hot air balloon reached a height of 205 feet before starting to descend. By substituting h = 205 into the original equation and confirming that it is satisfied, we may confirm this:

h - 130 = 75

205 - 130 = 75\s75 = 75

This demonstrates that h = 205 is a legitimate solution to the equation and, consequently, the hot air balloon's actual height.

The distribution of U is 0.8634.

The distribution of for this selection of numbers ~ n is 2.7.

The probability that the average of 39 numbers will be less than 2.7 is 80.69%.

Let X be the random variable that represents the number selected by the computer. Since the computer selects a number from 0 to 5 uniformly, the distribution of X is a discrete uniform distribution. This means that each number from 0 to 5 has an equal probability of being selected, which is 1/6 or approximately 0.1667

Population standard deviation = (5-0)/(12) = 1.4434

Therefore, the standard deviation of the sample mean for a sample size of 39 is:√

Standard deviation of sample mean = 1.4434/√(39) = 0.2319

To calculate the probability that the average of 39 numbers will be less than 2.7, the population mean (in this case, 2.5), σ is the population standard deviation, and n is the sample size.

Using the values we have calculated, we get:

z = (2.7 - 2.5) / (0.2319) = 0.8634

To find the probability of the sample mean being less than 2.7, we need to find the area under the standard normal distribution curve to the left of z = 0.8634.

The distribution of the sample mean for a sample size of 39, and the probability of the average of 39 numbers being less than 2.7.

B. The value for k in the transformation is -6.

C. The equation for transforming is g (x) = f (x) - 6.

What is transformation?

Shapes on a coordinate plane can be translated, rotated, and reflected using transformations. You can rotate, translate, or reflect any line, point, or vector.

A. The two types of transformations that can be used to transform f(x) to g(x) are translation and reflection.

Translation means shifting the graph left, right, up or down.

Reflection means creating a mirror image over x - axis or y - axis.

B. Both the transformations will have the same k value.

The graph g (x) is the translation of f (x) towards left with 6 units.

So, the value of k is -6.
