Answer:

mean for data set 1 is 41

data set 1 MAD is 16.4

data set 2 MAD is 16.8

mean for data set 2 is 38

Step-by-step explanation:

Finding the mean:

formula: sum of the data set / total number of terms

sum of the data set: 18 + 29 + 35 + 58 + 65 = 205

total number of terms: there is 5 numbers in the data set

mean = 205 / 5

mean = 41

MAD (Mean Absolute Value):

step 1: Find the mean of the data (above)

step 2: Find the distance between each data and mean.

18, 29, 35, 58, 65

Distance between 18 and 41 is 23 (41 - 18 = 23)

Distance between 29 and 41 is 12 (41 - 29 = 12)

Distance between 35 and 41 is 6 (41 - 35 = 6)

Distance between 58 and 41 is -17 (41 - 58 = -17)

Distance between 65 and 41 is -24 (41 - 65 = -24)

step 3: take the absolute value of any negative numbers

|-17| and |-24| is 17 and 24

step 4: add all the distances

23 + 12 + 6 + 17 + 24 = 82

step 5: divided it by the number of data

82 / 5 = 16.4

formula: sum of the data set / total number of terms

sum of the data set: 19 + 26 + 27 + 45 + 73 = 190

total number of terms: there is 5 numbers in the data set

mean = 190 / 5

mean = 38

MAD (Mean Absolute Value):

step 1: Find the mean of the data (above)

step 2: Find the distance between each data and mean.

19, 26, 27, 45, 73

Distance between 19 and 38 is 19 (38 - 19 = 19)

Distance between 26 and 38 is 12 (38 - 26 = 12)

Distance between 27 and 38 is 11 (38 - 27 = 11)

Distance between 45 and 38 is -7 (38 - 45 = -7)

Distance between 73 and 38 is -35 (38 - 73 = -35)

step 3: take the absolute value of any negative numbers

|-7| and |-35| is 7 and 35

step 4: add all the distances

19 + 11 + 12 + 7 + 35 = 84

step 5: divided it by the number of data

84 / 5 = 16.8

What is the length of side c

Nutka1998 [239]

c ≈ 16.7 ( to 1 dec. place ) → d

since triangle ABC is right use the cosine ratio to find c

cos33° = $\frac{adjacent}{hypotenuse}$ = $\frac{14}{c}$

multiply both sides by c

c × cos33° = 14 ( divide both sides by cos33° )

x = $\frac{14}{cos33}$ ≈ 16.7 ( to 1 dec. place )

Students in a school were asked to collect old bottles as part of a recycling drive. Some of the data recorded at the drive is s

Basile [38]

Answer:

The number of students who collected exactly 9 bottles.

Step-by-step explanation:

The given histogram shows the number of students who participated in the recyling drive & their old bottle waste collection.

We can find out the total number of students who participated just by looking at the histogram (students = 10), the number of students who colected bottles below 7 or 3 bottles etc.

But since the number of bottles is given in the form of grouped data, one cannot infer the exact number of bottles collected by students.

Hence, out of the given statements, 'The number of students who collected exactly 9 bottles' is the incorrect one.

A rectangle initially has dimensions 3 cm by 6 cm. All sides begin increasing in length at a rate of 3 cm divided by s 3 cm/s. A

Setler [38]

Answer:

405 cm²/s

Step-by-step explanation:

The dimensions are increasing at the rate of 3 cm/s, so the dimensions in cm can be described as a function of time by ...

3 + 3t

and

6 + 3t

Then the area is the product of these, or ...

A = (3 +3t)(6 +3t)

A = 9t² +27t +18

and the rate of change of area is given by its derivative with respect to t:

A' = 18t +27

When t=21, the value of this is ...

A'(21) = 18·21 +27 = 405 . . . . cm²/s
