Answer:
σ =2√2 .....
Step-by-step explanation:
Lets find the mean first
mean = 2+4+6+8+10/5
m = 30/5
m = 6
σ =√1/5[(2-6)²+(4-6)²+(6-6)²+(8-6)²+(10-6)²]
σ = √1/5[(-4)²+(-2)²+(0)²+(2)²+(4)²]
σ=√1/5[(16+4+0+4+16)]
σ = √1/5(40)
σ = √8
Take the square root of 8.
σ =2√2 .....
7/1 would be your answer. :)
Therefore the reminder is 3 when 5n is divided by 7.
Step-by-step explanation:
we know that
Dividend = quotient × Divisor +Reminder
⇔ n = Q(n) × 7 + 2 [ let Q(n) is quotient]
multiplying by 5 both sides
5n = 5 Q(n) ×7 + 2×5
⇔5n = 5 Q(n) ×7 +10
⇔5n= 5 Q(n) ×7 +7 +3
⇔ 5n = (5Q(n) +1) × 7 +3
Therefore the reminder is 3 when 5n is divided by 7.
Answer:
The slope is 2/3
Step-by-step explanation:
The line crosses through the blue grid lines leaving gaps on each. Find two points which cross at an intersection such as (0,30) and (30,50). Find the slope by substituting these points into the slope formula:
