Step-by-step explanation:
Range is the least number (50) subtracted from the greatest number (90)
90-50 = 40 (range)
The most dots is at 70 and the chart is symmetrical.
3wx^2 it is the same as 5-2
A right angle = 90 degree
BOC = 3/5 of the right angle
= 3/5 x 90
= 54 degree

Step-by-step explanation:
Answer:
B. 
Step-by-step explanation:
We have,
The first term of the series,
.
The common difference is given by,
i.e.
.
Since, the given series is an infinite series, then,
Sum of an infinite series = 
i.e. Sum the series = 
i.e. Sum the series = 
i.e. Sum the series = 
i.e. Sum the series = 
i.e. Sum the series = 
Thus, the sum of the series is
.
