Increase of 7% from February to march: 4100*107/100= 4387
The 500 increase from March to April: 4387+500= 4887
Formula of change: amount of change/ original amount *100.
500/4837*100= 11,397%

Answer: The percentage change is 16%.

Step-by-step explanation:

February:

4,100 water bottles.

March:

(4,100 + 7/100 x 4,100) water bottles

(4,100 + 287) water bottles.

4,387 water bottles.

April:

(500 + 4,387) water bottles.

4,887 water bottles.

= (4,887 - 4,100) / 4,887 x 100

= 787/4,887 x 100

= 16%

The percentage change is 16%.

running out of constant rate Gina ran 15 miles in a time of 150 minutes how many minutes does it take to run in 6 minutes?

Answers

Answer: 60 minutes

Step:

Divide by 15
X=60

Answer:

.6 or 6/10 of a mile

Step-by-step explanation:

Divide 150 by 15 which equals 10 which means that Gina was moving at 1 mile in 10 minutes. So now we know that Gina was moving at .1 or 1/10 mile a minute so 6 minutes is 6/10 or .6 of a mile.

Answer:

Step-by-step explanation:

You want the quotient of 2.85×10⁶ and 30,000 written in scientific notation.

Division

It is convenient to adjust the exponents of the operands so the coefficient of the quotient has a value between 1 and 10.

$\dfrac{2.85\times10^6}{30,\!000}=\dfrac{2.85\times10^6}{0.3\times10^5}=9.5\times10^{6-5}=\boxed{9.5\times10^1}$

Answer: Alligators

Step-by-step explanation: This entire paper is just about combining like terms.

I won't go too in depth about it since it's self-explanatory, but I'll explain it just a bit. Like terms are two terms that have the same variable. For example, 19 and 24 are like terms since they are both numbers. 15x and 18x are like terms since they are both the same variables. 2y and 5y are like terms since they are both the same variables. However, 3x and 4y are NOT like terms, they do not have the same variable.

Also, variables that have different exponential powers are also not like terms. For example, 5x^2 and 7x are not like terms as one is squares and one is to the 1st power. Similarly, 3x^3 is not the same variable as 2x^4.

When you have 5x and -2x, you subtract 5x and 2x. Thus, the combination would be 3x. When you have -4x - 2x, you would get -6x, and if you have -4x + 2x, you would get -2x.

What you were supposed to do is simplify the equations by combining like terms, and then crossing off the letters that correspond to what you have left in the expression. The remaining letters should spell out a joke.

Part A: Calculate the measures of center. Show all work. (2 points)

Part B: Calculate the measures of variability. Show all work. (1 point)

Part C: If you are interested in a smaller class size, which school is a better choice for you? Explain your reasoning. (1 point)

Answers

To calculate the measures of center, we need to find the mean and median for each school.

For Mountain View School:
Data: 0, 0, 0, 0, 1, 2, 3, 4, 4, 5, 5, 5, 5, 6, 7, 8, 8, 8, 9
Mean: (0 + 0 + 0 + 0 + 1 + 2 + 3 + 4 + 4 + 5 + 5 + 5 + 5 + 6 + 7 + 8 + 8 + 8 + 9) / 19
= 100 / 19
≈ 5.26

To find the median, we need to arrange the data in ascending order: 0, 0, 0, 0, 1, 2, 3, 4, 4, 5, 5, 5, 5, 6, 7, 8, 8, 8, 9.
The median is the middle value, which is the 10th value in this case.
Median: 5

For Seaside School:
Data: 0, 0, 0, 1, 1, 2, 2, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 9
Mean: (0 + 0 + 0 + 1 + 1 + 2 + 2 + 4 + 5 + 5 + 5 + 5 + 6 + 7 + 7 + 8 + 8 + 8 + 9) / 19
= 80 / 19
≈ 4.21

To find the median, we need to arrange the data in ascending order: 0, 0, 0, 1, 1, 2, 2, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 9.
The median is the middle value, which is the 10th value in this case.
Median: 5

Now let's calculate the measures of variability, specifically the range and interquartile range (IQR).

Range: The range is the difference between the largest and smallest values in the dataset.

For Mountain View School:
Range: 9 - 0 = 9

For Seaside School:
Range: 9 - 0 = 9

Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1) and measures the spread of the middle 50% of the data.

For Mountain View School:
Q1 = 3
Q3 = 7
IQR = Q3 - Q1 = 7 - 3 = 4

For Seaside School:
Q1 = 2
Q3 = 7
IQR = Q3 - Q1 = 7 - 2 = 5

To determine which school is a better choice for a smaller class size, we can consider both the mean and the median.

Both the mean and median for Mountain View School are higher than those for Seaside School. This suggests that, on average, the class sizes at Mountain View School are larger than those at Seaside School. Therefore, if you are interested in a smaller class size, Seaside School would be a better choice

Part A:

For Mountain View School:
- Median: The median class size is the middle value, which is 25.
- Mean: The mean class size is the sum of all the class sizes divided by the total number of classes, which is (29 + 28 + 28 + 27 + 25 + 24 + 24 + 23 + 21 + 20 + 19 + 18 + 15 + 13 + 10) / 15 = 21.27.

For Seaside School:
- Median: The median class size is the middle value, which is 20.
- Mean: The mean class size is the sum of all the class sizes divided by the total number of classes, which is (25 + 25 + 27 + 27 + 28 + 28 + 28 + 30 + 31 + 35 + 36 + 38 + 40 + 43 + 45) / 15 = 31.13.

Part B:

For Mountain View School:
- Range: The range is the difference between the largest and smallest values, which is 29 - 10 = 19.
- Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). From the stem-and-leaf plot, we can see that Q1 is 20 and Q3 is 28. Therefore, the IQR is 28 - 20 = 8.

For Seaside School:
- Range: The range is the difference between the largest and smallest values, which is 45 - 25 = 20.
- Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). From the stem-and-leaf plot, we can see that Q1 is 27 and Q3 is 38. Therefore, the IQR is 38 - 27 = 11.

Part C:

If you are interested in a smaller class size, Mountain View School is a better choice for you because it has a lower mean and median class size than Seaside School.

To estimate the mean number of vehicles owned using a sample, Theo needs to randomly select the people he will survey so that his sample represents the population well.

a committee consisting of 4 faculty members and 5 students is to be formed. every committee position has the same duties and voting rights. there are 7 faculty members and 13 students eligible to serve on the committee. in how many ways can the committee be formed?

Answers

C(7, 4) = 7! / (4!(7-4)!) = (7 * 6 * 5) / (3 * 2 * 1) = 35

and

C(13, 5) = 13! / (5!(13-5)!) = (13 * 12 * 11 * 10 * 9) / (5 * 4 * 3 * 2 * 1) = 1287

Multiply these two combinations since the faculty members and students are selected independently:

Total number of ways to form the committee = C(7, 4) * C(13, 5) = 35 * 1287 = 45,045

Therefore, there are 45,045 ways to form the committee consisting of 4 faculty members and 5 students.

To determine the number of ways to form the committee with 4 faculty members and 5 students, we need to calculate the combinations of faculty members and students separately and then multiply them together.

For faculty members:
There are 7 eligible faculty members, and we need to select 4 of them for the committee. This can be done using the combination formula:

C(7, 4) = 7! / (4!(7 - 4)!) = 35.

So, there are 35 ways to select 4 faculty members from the 7 eligible ones.

For students:
There are 13 eligible students, and we need to select 5 of them for the committee. Using the combination formula again:

C(13, 5) = 13! / (5!(13 - 5)!) = 1287.

Therefore, there are 1287 ways to select 5 students from the 13 eligible ones.

To form the committee, we multiply the number of ways to select faculty members by the number of ways to select students:

35 * 1287 = 44,895.

Hence, there are 44,895 ways to form the committee consisting of 4 faculty members and 5 students from the eligible candidates.

Answer:

x = 7.5, y = 8.5

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

The two angles with the variable x form a linear pair and therefore:

16x - 18 + 10x + 3 = 18026x - 15 = 18026x = 195x = 195/26x = 7.5

Angles 16x - 18 and 12y are congruent as vertical angles:

16*7.5 - 18 = 12y102 = 12yy = 102/12y = 8.5

Answer:

x = 7.5

y = 8.5

Step-by-step explanation:

Linear Pair

Two adjacent angles that sum to 180° (two angles which when combined together form a straight line).

To find x, equate the sum of the two angles with the variable x to 180° and solve:

⇒ (16x - 18)° + (10x + 3)° = 180°

⇒ 16x - 18 + 10x + 3 = 180

⇒ 26x - 15 = 180

⇒ 26x = 195

⇒ x = 7.5

Vertical Angles Theorem

When two straight lines intersect, the opposite vertical angles are congruent.

Therefore:

⇒ (16x - 18)° = 12y°

Substitute the found value of x into the equation and solve for y:

⇒ 16x - 18 = 12y

⇒ 16(7.5) - 18 = 12y

⇒ 120 - 18 = 12y

⇒ 102 = 12y

⇒ y = 8.5
