Answer: Yes it is rational
Any rational number is of the form p/q where p, q are integers. The value of q cannot be 0.
In this case, p = 333 and q = 106.
Answer:
Option C.
Step-by-step explanation:
It is given that the first term of the arithmetic sequence is 8 and second term is 5.
We know that the explicit equation of an AP is
, where n is an integer greater than or equal to 1.
where, a is first term and d is common difference.
So, domain of this explicit equation is all integers where n ≥ 1.
Therefore, the correct option is C.
Answer:
Variance = 1,227.27
Standard deviation = 35.03
Step-by-step explanation:
To calculate these, we use the following formulas:
Mean = (sum of the values) / n
Variance = ((Σ(x - mean)^2) / (n - 1)
Standard deviation = Variance^0.5
Where;
n = number of values = 20
x = each value
Therefore, we have:
Sum of the values = 29 + 32 + 36 + 40 + 58 + 67 + 68 + 69 + 76 + 86 + 87 + 95 + 96 + 96 + 99 + 106 + 112 + 127 + 145 + 150 = 1,674
Mean = 1,674 / 20 = 83.70
Variance = ((29-83.70)^2 + (32-83.70)^2 + (36-83.70)^2 + (40-83.70)^2 + (58-83.70)^2 + (67-83.70)^2 + (68-83.70)^2 + (69-83.70)^2 + (76-83.70)^2 + (86-83.70)^2 + (87-83.70)^2 + (95-83.70)^2 + (96-83.70)^2 + (96-83.70)^2 + (99-83.70)^2 + (106-83.70)^2 + (112-83.70)^2 + (127-83.70)^2 + (145-83.70)^2 + (150-83.70)^2) / (20 - 1) = 23,318.20 / 19 = 1,227.27
Standard deviation = 1,227.27^0.5 = 35.03
Answer:
angles 6 and 8
Step-by-step explanation:
angles 7 and 9
angles 1 and 4
what grade r u in btw ?
So find out how many ones there are
15/15=1 so find out how many 15's are in 32
32=15+15+2
32/15=15/15+15/15+2/15=1+1+2/15=2+2/15=2 and 2/15
answer is 2 and 2/15
