Step-by-step explanation:
Jorge invested a total of $5000. He invested some of his money at 4% and the rest at 7%. If the total return at the end of the year was $320, how much was invested at each rate?
Answers
Step-by-step explanation:
Let's solve this problem using a system of equations.
Let's assume that Jorge invested x dollars at 4% interest and (5000 - x) dollars at 7% interest.
The interest earned from the 4% investment can be calculated as (4/100) * x.
The interest earned from the 7% investment can be calculated as (7/100) * (5000 - x).
According to the problem, the total return at the end of the year was $320. Therefore, we can set up the following equation:
(4/100) * x + (7/100) * (5000 - x) = 320
Simplifying and solving for x:
(4/100) * x + (7/100) * 5000 - (7/100) * x = 320
0.04x + 0.07(5000 - x) = 320
0.04x + 350 - 0.07x = 320
-0.03x = -30
x = -30 / -0.03
x = 1000
Jorge invested $1000 at 4% interest and the remaining amount, $5000 - $1000 = $4000, at 7% interest.
Therefore, Jorge invested $1000 at 4% and $4000 at 7%.
The stem-and-leaf plot displays data collected on the size of 15 classes at two different schools.

Key: 2 | 1 | 0 means 12 for Mountain View and 10 for Seaside
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
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
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.

so the value is 32
The value of the expression for m = 6 and n = 18 is 16,79,600.
What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given is the expression as -
m⁸ - (34 - n)
The expression given is -
m⁸ - (34 - n)
Now, for m = 6 and n = 18, we can write -
6⁸ - 34 + 18
6⁸ - 16
(6 x 6) x (6 x 6) x (6 x 6) x (6 x 6) - (16)
36 x 36 x 36 x 36 - 16
16,79,616 - 16
16,79,600
Therefore, the value of the expression for m = 6 and n = 18 is 16,79,600.

A water well drilling rig has dug to a height of -60 feet after one full day of continuous use.
Assuming the rig drilled at a constant rate, what was the height of the drill after 15 hours?
Answers
Answer:
-3.75 feetStep-by-step explanation:
If the water well drilling rig dug to a depth of -60 feet after one full day of continuous use, we can assume that the rig drilled at a constant rate throughout the day.
To determine the height of the drill after 15 hours, we need to calculate the average rate of drilling per hour.
PLEASE MARK AS BRAINLIEST
The rate of drilling can be calculated by dividing the total depth (-60 feet) by the total time (24 hours):
Rate of drilling = Total depth / Total time
= -60 feet / 24 hours
= -2.5 feet per hour
Now we can calculate the height of the drill after 15 hours using the rate of drilling:
Height of the drill after 15 hours = Rate of drilling × Time
= -2.5 feet per hour × 15 hours
= -37.5 feet
Therefore, the height of the drill after 15 hours is -37.5 feet.

A line passes through the point (2,-6) and has an initial value of 6. What is the rate of change for this line?
A. -12
B. -6
C. -1/6
D. 6
Answers
Just did the question
-6
We assume "initial value" means the y-intercept is (0, 6). The rate of change is the "rise" divided by the "run" between the two points.
rise = -6 -6 = -12 . . . . difference of y-values
run = 2 -0 = 2 . . . . . . difference of corresponding x-values
rate of change = rise/run = -12/2 = -6
The rate of change of this line is -6.
