Answer:
D (Alicia did 5 more jumping jacks per minute than Melissa.)
Step-by-step explanation:
Alicia's rate is 30 jumping jacks per minute. You can use the formula m=(y2-y1)/(x2-x1) to find the slope/rate. The two points in the table you can use are (1,30) and (2,60). You can plug those coordinates into the slope formula. (60-30)/(2-1)=30/1= 30 jumping jacks per minute. To find the rate of change/slope for Melissa, you can use the same formula m=(y2-y1)/(x2-x1). The two points you could plug in are (0,0), and (4,100). (100-0)/(4-0)=100/4=25. Melissa does 25 jumping jacks per minute.

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.

Ginny bought 2.2 pounds of bananas at a cost of $0.49 per pound and 1.3 pounds of grapes at a cost of $1.29 per pound. What was the total cost of the bananas and grapes Ginny purchased?
Answers
Answer:
$2.76
Step-by-step explanation:
Price per pound times the number of pounds Ginny bought
Bananas:
2.2*0.49 = 1.078 -> 1.08
Grapes:
1.3*1.29 = 1.677 -> 1.68
Now, to find the total cost of both, add the prices together
1.08 + 1.68 = 2.76
Answer:
$2.76
Step-by-step explanation:
one pound of bananas cost $0.49 , multiply this cost by 2.2 to find the cost at this weight.
2.2*0.49=1.078=1.08
1.3*1.29=1.677=1.68
1.08+1.68=2.76

How can I find the cube root of 64?
Answers
Answer:
4
Step-by-step explanation:
The cube root of 64 is the number which when multiplied by itself three times gives the product as 64. Since 64 can be expressed as 2 × 2 × 2 × 2 × 2 × 2. Therefore, the cube root of 64 = ∛(2 × 2 × 2 × 2 × 2 × 2) = 4.
The cube root of 64 is 4.
Before solving the question, let's understand the concept of cube root.
The cube root of a number is the value obtained by multiplying it by itself three times or thrice. When we multiply 3 by itself three times, we get 3 x 3 x 3 = 27 = 3³, so the cube root of 27 is 3. Thus, we can say that the cube root gives a value that is basically cubed.
The cube root is denoted by ∛
Now, we will find the cube root of 64.
Firstly, we have to find factor 64.
64 = 2 × 2 × 2 × 2 × 2 × 2.
64 = ∛4³
64 = 4
Therefore, the cube root of 64 is 4.

Answer:
y= (-2/3)x+5
Step-by-step explanation:
We can use slope-intercept form to figure this out. y=mx+b
First, the y-intercept is given (0,5). y-int=5
To find the slope, we need any 2 points.
\(slope=\frac{y_2-y_1}{x_2-x_1}\)
If we use (0,5) and (3,3)
\(\frac{3-5}{3-0} =\frac{-2}{3}\)
Put into slope-intercept form y=mx+b
\(y=\frac{-2}{3}x+5\)
Answer:
y = -⅔x +5Step-by-step explanation:
y = -0.666666667x+5
or
y = -⅔x +5
how?
well as you can see on the first box (0,5)
we can already know by this the equation will look like
y = _x +5
since if x is 0, we will already have +5
now onto the next box to help us
(1.5,4)
lets subtract 5 from 4 to find out what the slope will be
4-5=-1 and then divide that by our x
1 / 1.5 = -0.666666667
so our equation is
y = -0.666666667x+5
or
y = -⅔x +5

using the two points (2,2) and (6,10), the slope is 4/8. simplified, it is 1/2.
We can conclude -
slope of the line [m] = 2equation of the line → y = 2x - 2a = 5 and b = 6At x = 0, y = -2.What is the general equation of a Straight line?The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.
The equation of a straight line can be also written as -
Ax + By + C = 0
By = - Ax - C
y = (- A/B)x - (C/A)
Given is a graph in the image.
The slope of the line will be -m = (10 - 2)/(6 - 2) = 8/4 = 2
Assume the equation to be y = 2x + c. We can write the equation for point (2, 2) as → 2 = 2 x 2 + c → c = - 2. Now, the equation of the line will be y = 2x - 2(8 - 2)/(a - 2) = 2 → 6 = 2(a - 2) → 2a = 10 → a = 5(b - 2)/(4 - 2) = 2 → (b - 2)/2 = 2 → b - 2 = 4 → b = 6At x = 0, y = -2.Therefore, we can conclude -
slope of the line [m] = 2equation of the line → y = 2x - 2a = 5 and b = 6At x = 0, y = -2.To solve more questions on straight lines, visit the link below-

An object has a mass of 17 grams.
What is its weight in ounces?
Use 1 ounce=28.35 gram to write the conversion facto
Answers
Step-by-step explanation:
In order to determine the weight of an object in ounces, we need to convert its mass from grams to ounces using the conversion factor of 1 ounce = 28.35 grams. Since the mass of the object is 17 grams, we can use the conversion factor to calculate its weight in ounces as follows:
17 grams * (1 ounce / 28.35 grams) = 0.6 ounces
Therefore, the weight of the object in ounces is 0.6 ounces. The conversion factor used in this calculation is 1 ounce = 28.35 grams.

The volume of a box can be found using the following equation:
Volume of box = width x length x height.
It is given to us that:
length = 1 ft.
width = 2/3 ft.
height = 1/4 ft.
Multiply the 3 measurements together:
V (volume) = 1 x 2/3 x 1/4
V = (1 * 2 * 1)/(3 * 4) = 2/12 ft³ , or if simplified 1/6 ft³
1/6 ft³ is your answer.
