Answer: 109 years old
Step-by-step explanation:
2009-1900=109
Step-by-step explanation:
Next term is - 51
Use formula Tn=a+(n-1)d
a=the first term of the sequence which is - 15
d=the difference between the terms which is - 9
Substitute
Tn=-15+(n-1)(-9)
Tn=-15+9-9n
Tn=-9n-6
From this you will be able to generate all the terms in the pattern
If they say determine the 50th term just substitute 50 by n
Tn=-9(50)-6
Tn=-450-6
Tn=-456
Answer:
Products Repaired Frequency
DVD Player 7
TV 3
Radio 3
MP3 Player 5
Blu-ray Player 7
Total = 25
Step-by-step explanation:
Frequency distribution table represent the information of a data in a tabular form telling us about the items present in the sample and the number of times it occur.
Each item was picked from the list and written under 'Products repaired' then the number of times each item appeared is the frequency.
Answer:
15
Step-by-step explanation:
|-7|=7
|8|=8
7+8=15
A pentagon is a closed 5 sided polygon.
A regular polygon has all sides equal as well as all angles equal.
°The formula to find the sum of all angles of a polygon is = (n-2) ×180
So for a pentagon, n= 5
So the sum of all the angles must be (5-2)× 180= 3 × 180 = 540.
Now as it is a pentagon, it shall have 5 vertices.
So there are 5 angles in a pentagon and all must be equal.
Hence each interior angle must be 540/5 = 108
So for a regular polygon with 5 sides must have each interior angle = 108
