Answers
Answer:
2682
Step-by-step explanation:
he walked 282 feet from below sea level and is now at ground level, so he increase by 282 then he continues 2400 feet, so he walked 282 in below sea level plus the 2400 feet above ground level, so 282 plus 2400 equals 2682

Y= mx + b
so Y = 1/3x + 2
just substitute
Now, we shall use points (3,2) as the substitutes for the solution for b, which 3 would be the input and 2 would be y.
Therefore, 2 = 1/3(3) + b
2 = 1 + b, therefore, one would be subtracted from 2 which would give us the answer of b equaling to one. Thus, y = 1/3x + 1

Multiply the pairs of numbers and match them with their products. Tiles (-5)(4.2) (-7)(-3) (4) (5) (2.5)(-9) Pairs 22.5 21 -22.5 -21 111
Answers
Here are the pairs matched with their products:
- (-5)(4.2) matches with -21
- (-7)(-3) matches with 21
- (2.5)(-9) matches with -22.5
Pairs (4) and (5) do not have corresponding products in the given options.
(-5)(4.2) = -21
(-7)(-3) = 21
(4)(5) = 20
(2.5)(-9) = -22.5
So, the pairs of numbers and their products are as follows:
(-5)(4.2) = -21 matches with -21.
(-7)(-3) = 21 matches with 21.
(4)(5) = 20 matches with 20.

you bought a magazine for $5 and four erasers. you spent a total of $25. how much did the eraser cost?
Answers
Answer:
1 eraser = $54 erasers = $20Step-by-step explanation:
Given that,
→ Magazine = $5
→ Total cost = $25
→ 1 eraser = x
The equation will be,
→ 4x + 5 = 25
Now the value of x will be,
→ 4x + 5 = 25
→ 4x = 25 - 5
→ x = 20/4
→ [ x = $5 ]
Hence, value of x is $5.
Total= $25- $5 magazine leaves you with $20. You bought 4 erasers so you do 20/4 which is $5

-A 6 inch x 9 inch rectangular cake ban that is 2 inches deep
Which of these pans has the larger volume? Justify your answer.
Answers
Answer:
114 in²
Step-by-step explanation:
The answer isround cake
- 82.42 in²rectangular cake - 114 in²
Round cake:
d = 7 inr =
d/2 = 7 in / 2 = 3.5 inh = 2 in
The surface are of a cylinder is:
A = 2πr² + 2πrh
The surface are of the round cake (which is actually a cylindrical cake) excluding the bottom is:
A = 2πr² + 2πrh - πr²A = πr² + 2πrh
A = 3.14 * 3.5² + 2 * 3.14 * 3.5 * 2 = 38.46 + 43.96 = 82.42 in²
Rectangular cake:w = 6 inl = 9 inh = 2 in
The surface are of a rectangle is:
A = 2wl + 2wh + 2lh
The surface are of the rectangular cake excluding the bottom is:A =
2wl + 2wh + 2lh - wlA = wl + 2wh + 2lhA = 6 * 9 + 2 * 6 * 2 + 2 * 9 * 2 = 54 + 24 + 36 = 114 in²

the volume of the right circular cylinder in 144π cubic yards. if h, the height of the cylinder is 4 yards, what is r, the radius of the base?
Answers
If the volume of the cylinder is 144π cubic yards and the height of the cylinder is 4 yards, you can set up the equation:
144π = πr^2 * 4
You can then solve for r by dividing both sides of the equation by 4π:
r^2 = 36
r = 6
Thus, the radius of the base of the cylinder is 6 yards.
Answer:
r = 6
Step-by-step explanation:
The formula for the volume of a cylinder is V = πr^2h,
If the volume of the cylinder is 144π cubic yards and the height of the cylinder is 4 yards it can be written as 144π = πr^2 * 4
You can then solve for r by dividing both sides of the equation by 4π:
r^2 = 36
r = 6

Three research departments have 8 ,10 , and 7 members, respectively. Each department is to select a delegate and an alternate to represent the department at a conference. In how many ways can this be done?
Answers
We can conclude that exists 211680 ways.
How many ways can this be done?We know that the three research department is have 8, 10, and 7 members.
We choose a delegate and an alternate to represent the department.
First case: department have 8 members.
So, for a delegate, we have 8 options, and for a alternate 7, so a total of
\(8 \times 7 = 56 \ \text{options}\)
Second case: department have 10 members.
So, for a delegate, we have 10 options, and for a alternate 9, so a total of
\(10\times 9 =90 \ \text{options}\)
Third case: department have 7 members.
So, for a delegate, we have 7 options, and for a alternate 6, so a total of
\(7\times6 = 42 \ \text{options}\)
Therefore, we get:
\(56 \times 90 \times 42 = \bold{211680}\)
Hence, we conclude that exists 211680 ways.
For a similar problem about this, please click the link below:
https://brainly.com/question/30958797
For the first department with 8 members, there are 8 choices for selecting a delegate. After choosing a delegate, there remain 7 members, so there are 7 choices for selecting an alternate. Therefore, there are 8 × 7 = 56 ways to select a delegate and an alternate from the first department.
Similarly, for the second department with 10 members, there are 10 choices for selecting a delegate and 9 choices for selecting an alternate. Hence, there are 10 × 9 = 90 ways to select a delegate and an alternate from the second department.
For the third department with 7 members, there are 7 choices for selecting a delegate and 6 choices for selecting an alternate. Thus, there are 7 × 6 = 42 ways to select a delegate and an alternate from the third department.
To find the total number of ways to select delegates and alternates from all three departments, we multiply the number of choices for each department together:
56 × 90 × 42 = 211,680.
Therefore, there are 211,680 ways to select a delegate and an alternate from each department.

Answer:
Mean = 16
Step-by-step explanation:
MEAN can be find bg the sum of all score divided by the amount of the score.
Mean = total amount / number of amount
Total amount = 2 + 3 + 5 + 9 + 17+ 22 + 31 + 39
= 128
number of amount = 2, 3, 5, 9, 17, 22, 31, 39
= 8
Then we can calculate mean as
Mean = 128/8
Mean = 16
2+3+5+9+17+22+31+39=128
128/8=16

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.
