Answer:
Half of the under 30's are from 5 to 18 seconds
Step-by-step explanation:
Each section of the box plot is 25%
Under 30's From 5 to 12 is 25% and from 12 to 18 is 25%
so from 5 to 18 is 50%
Answer:
−7<x<3 or (-7,3)
Step-by-step explanation:
The rate at which Charles amount increased will be given by:
Amount owe=$390
Payment=$10
Number of payments=10
thus using the formula:
A=P(1+r)^n
plugging the values we get:
390=10(1+r)^10
solving for r we get
39=(1+r)^10
r=0.4425
thus the amount increased by 44.25%
Answer:
No
Step-by-step explanation:
In a geometric sequence there is a common ratio. The common ratio is the number that when multiplied by a number in the sequence gives you the next number. To find the common ratio, you divide any number by the previous number. Every division must give you the same answer, the common ratio.
Now try to find the common ratio of this sequence.
36/12 = 3
12/3 = 4
The ratios between terms are not equal. There is no common ratio.
Therefore, this sequence is not a geometric sequence.
