Answer:
The answer is 48 square meters
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 teacher select a sample of n =15 students. And he wanted to know if teaching a smaller class was more effective and students performed better, that means if
and he obtaind a sample mean of
.
Based on this the correct system of hypothesis are:
Null hypothesis: 
Alternative hypothesis: 
And the best option for this case is:
a. H0:
vs. H1:
.
Step-by-step explanation:
For this case we have the following previous info given:
represent the true mean
represent the true deviation
