There is a proportional relationship between your distance from a thunderstorm and the time from when you see the lightning and
eimsori [14]

Answer:

Yes.

Step-by-step explanation:

The relation would be 3 = k*9  as there is a direct proportional relationship.

So k = 3/9 = 1/3  and we can write the relation as d = 1/3 t   where d=distance and t = time.

So if we double the time t we have:-

d = 1/3 * 18

= 6 kilometers.

So the distance is doubled.

What is the range for this set of data? 7, 15, 12Mrs. Juarez graded ten English papers and recorded the scores. 92, 95, 100, 62,
ra1l [238]

Answer:

Following are the solution to the given question:

Step-by-step explanation:

Please find the complete question in the attached file.

Arrange the value into the ascending order:

62, 88, 89, 90, 92, 95, 96, 98, 100, 100

Calculating the Range:

= Greatest - Lowest\\\\= 100 - 62\\\\ = 38

Outlier =  This might be the value "far" from other data values= 62

The range of scores would be, sans outlier,

 88, 89, 90, 92, 95, 96, 98, 100, 100

Calculating the range without outlier = 100 - 88 = 12

Inter Quartile Range = Q_3 - Q_1

IQR = 98 - 89 = 11

Calculating the IQR without outlier = 99 - 89.5 = 9.5

Therefore,

Option a is "True".

Option b is "True".

Option c is "True".

Option d is "False".

Option e is "False".

Option f is "True".

PLEASE HELP ASAP!!!
Elan Coil [88]

Answer:

The number is 5

Step-by-step explanation:

6+3n = 5n-4

Subtract 3n from each side

6+3n-3n = 5n-3n-4

6 = 2n-4

Add 4 to each side

6+4 = 2n-4+4

10= 2n

Divide by 2

10/2 =2n/2

5=n
