Since an arithmetic sequence is a sequence of numbers and the difference of any two successive members of the sequence is a constant
So this question is arithmetic because it keep minus by 7
from 19 - 7 = 12
12 - 7 = 5
5 - 7 = -2
so common difference is -7
or you can check with arithmetic formular as
= 
+ (n−1)d
I will just put in the 4th term which is -2 and n will equal to 4
and is the 1st term which is 19
-2 = 19 + (4−1)d
-2 - 19 = 3d
d = 
d = -7
-- Take a piece of paper
-- Take a pencil or a pen
-- Write the first nine or ten terms of the sequence:
Term Value
#1 0
#2 0.5
#3 1
#4 1.5
#5 2
#6 2.5
#7 3
#8 3.5
#9 4
#10 4.5
-- Now, find the graph of that sequence of numbers.
Hint: It's Graph-D .
Answer:
b. Shift left 3 units
Step-by-step explanation:
You're given
y = √(x + 3)
y = √(x - (-3))
y = √(x - <em>amount_shifted</em>)
amount shifted = -3
so shifted 3 units and the negative means it's shifted to the left
Answer:
(A)12-19
Step-by-step explanation:
To construct a frequency distribution, we follow the steps below.
1. Find the largest and smallest values.
91 and 12 respectively
Compute the Range = Maximum - Minimum=91-12=79
2. Determine the number of classes desired.
In this case, we desire 10 classes
3. Next, we find the class width by dividing the range by the number of classes and rounding up.
79÷10 = 7.9
Rounded Up, Class Width=8
4. Pick a suitable starting point less than or equal to the minimum value.
Since our minimum value is 12, we pick a class starting with 12 and give a class width of 8.
Therefore the upper and lower limits of the first class is given as:
12-19.
