Answer:

The height appear to be reported because there are disproportionately more 0s and 5s.

Step-by-step explanation:

Given the data :

0 0 0 0 0 0 0 0 0 1 2 3 3 3 4 5 5 5 5 5 5 5 5 5 5 5 6 8 8 8 9

Creating a frequency table :

Last digit ______ Frequency

0 ______________ 9

1 _______________ 1

2 _______________1

3 _______________3

4 _______________ 1

5 _______________11

6 _______________ 1

8 _______________ 3

9 ________________1

From the frequency distribution table, it could be seen that the volumeof 5's and 0's are far more than the volume of the other digits. We could infer from this numbers were reported and not measured.

Solve the rational equation. If an equation has no solution, so state.<br>x+6/x=-7​
kupik [55]

Answer:

x=−1 or x=−6

Step-by-step explanation:

Multiply all terms by x and cancel:

xx+6=−7x

x2+6=−7x(Simplify both sides of the equation)

x2+6−−7x=−7x−−7x(Subtract -7x from both sides)

x2+7x+6=0

(x+1)(x+6)=0(Factor left side of equation)

x+1=0 or x+6=0(Set factors equal to 0)

x=−1 or x=−6

Check answers. (Plug them in to make sure they work.)

x=−1(Works in original equation)

x=−6(Works in original equation)

The following data points represent the number of animal crackers in each kid's lunch box.
OLga [1]

Answer:

IQR = 7

Step-by-step explanation:

To get the interquartile range of the set of data, the following steps must be followed:

Datas 4, 4, 6 , 7, 10 , 11 , 12, 14 ,15

Step 1: Rearrange the datas in ascending or descending order if not arranged.

4, 4, 6 7, 10, 11, 12, 14, 15

Step 2:

We will locate the (N+1/4)the cumulative value of the data where N is the total frequency of the data.

N = 4 + 4 + 6 + 7 + 10 + 11 + 12 + 14 + 15

N = 83

N+1/4 = 83+1/4

= 84/4

= 21st cumulative value

On cumulating the values up to the 21st value or more:

4 + 4 + 6 + 7

= 21

Since the 21st value falls on 7, then the interquartile range of the set of data is 7
