The following are the preening times (sec) for 20 flies:54 34 24 10 16 52 76 33 31 46 24 18 26 57 32 25 48 22 48 29 19 (a) Determine the mode (s). (b) Calculate the range. (c) Construct a dotplot of the data
Answers
Answer:
Step-by-step explanation:
The raw data given can be properly expressed by a frequency table. The frequency table formed from the data given is attached to this answer.
From the frequency table,
(a) The modes of the data are 24 and 48. Thus, the data is said to be bimodal.
(b) Range = height value - least value
= 76 - 10
= 66
Range = 66
(c) A dot plot is a pictorial graph of the plot of the given data. The plot of the given data is attached to this answer.

The graph of a function and a set of input values
The input values are given as
–2, 0, and 4
Next, we read the above input values from the graph
Using the above as a guide, we have the following:
f(-2) = 2
f(0) = 3
f(4) = -1
Hence, the values are f(-2) = 2, f(0) = 3 and f(4) = -1

Consider a sample with data values of 27, 24, 19, 14, 30, 35, 28, and 24. Compute the 20th, 25th, 65th, and 75th percentiles.
Answers
Answer:
20th percentile = 19
25th percentile = 21.5
65th percentile = 28
75th percentile = 30
Step by Step Explanation:
Computation for the 20th, 25th, 65th, and 75th percentiles
First step is to arrange sample with data values of 27, 24, 19, 14, 30, 35, 28, and 24 in Ascending order
Ascending order of given data
14,19,24,24,27,28,30,35
Now let Compute for the 20th, 25th, 65th, and 75th percentiles
Using this formula
I=P/100*n
Where,
n =8 given data values
Let plug in the formula
1. 20th PERCENTILE
20th PERCENTILE = (20/100) * 8
20th PERCENTILE= 1.6
20th PERCENTILE = 2 (rounded up to the nearest integer)
The 20th percentile is the 2th value in the given date that was arranged in ascending order which is 19
Therefore the 20th percentile is 19.
2. 25th PERCENTILE
25th PERCENTILE = (25/100) * 8
25th PERCENTILE= 2
To get the 25th percentile of 2 we would take the average of 2nd and 3rd value
25th PERCENTILE = (19 + 24)/2
25th PERCENTILE=43/2
25th PERCENTILE= 21.5
Therefore the 25th percentile is 21.5
3. 65th PERCENTILE
65th PERCENTILE = (65/100) * 8
65th PERCENTILE= 5.2
65th PERCENTILE= 6 (rounded up to the nearest integer)
The 65th PERCENTILE is the 6th value which is 28
Therefore 65th percentile is 28
4. 75th PERCENTILE
75th PERCENTILE = (75/100) * 8
75th PERCENTILE = 6
To get the 75th PERCENTILE of 6 we would take the average of 6th and 7th value
75th PERCENTILE = (28+30) / 2
75th PERCENTILE =58/2
75th PERCENTILE = 29
Therefore the 75th percentile is 30
Therefore the 20th, 25th, 65th, and 75th percentiles are:
20th percentile = 19
25th percentile = 21.5
65th percentile = 28
75th percentile = 30

Answers
Answer:
Distributive Property = 5y+2(y+3)+2
combining like terms = 5y+2+6+2y
Commutative Property = 6y-y+2y+10-4+2
Step-by-step explanation:
The correct matching of the properties will be:
Distributive Property = 5y+2(y+3)+2
combining like terms = 5y+2+6+2y
Commutative Property = 6y-y+2y+10-4+2
Original expression: 5y + 2(y + 3) + 2
How to match the valueApply the distributive property by multiplying 2 to the terms inside the parentheses:
5y + 2y + 6 + 2
Combine like terms:
(5y + 2y) + (6 + 2)
7y + 8
Rearrange the terms using the commutative property:
(7y + 2y) + (6 + 2)
9y + 8 + 8
Simplifying further, we have:
9y + 16
Therefore, the simplified expression is 9y + 16.

Initial temperature = 74°
After some time, the new temperature = 91°
We need to find the percent increase in the temperature.
The formula for the percentage increase is given by :
[tex]\%=\dfrac{|\text{final value-initial value}|}{\text{initial value}}\times 100\\\\=\dfrac{91-74}{74}\times100\\\\=22.97\%[/tex]

Nancy and Linda go to their favorite restaurant. Nancy has a $5 off coupon to use for her purchase of $30. Linda has a 10% off coupon to use for her purchase of $25. What is the difference between the total the friends will pay individually
Answers
Answer:
Step-by-step explanation:
2.50
The percentage is calculated by dividing the required value by the total value and multiplying it by 100.
If Nancy has to buy an item that cost $30 with a 5% off and Ninda has to buy an item that cost $25 with a 10% off.
The difference between individual pay is $6.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying it by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
We have,
Nancy:
Coupon = 5% off
Cost of the purchase = $30
Amount to pay:
= 30 - (5/100) x 30
= 30 - 30/20
= 30 - 1.5
= $28.5
Linda:
Coupon = 10% off
Cost of the purchase = $25
Amount to pay:
= 25 - (10/100) x 25
= 25 - 2.5
= $22.5
The difference between individual pay:
= 28.5 - 22.5
= $6
Thus
The difference between individual pay is $6.
