Answer:
(c*6)/b
Step-by-step explanation:
in plain and short, if the number inside the parentheses is less than 1, that's a flag is a decay, if it's more than 1, is growth.
3/5 is less than 1
12 is clearly more than 1
3/4 is less than 1
2.1 is more than 1
0.6 is less than 1
6 is more than 1.
1. the mean is 16
2. the mean is 22.5
the formula that can be used to calculate the mean is
= sum of terms/number of terms
for the first question the mean can be calculated as follows
sum of terms= 20+15+19+16+10
= 80
number of terms= 5
mean= 80/5
= 16
for the second question the mean can be calculated as follows
sum of terms= 19+23+11+30+27+27+22+26+16+24
= 225
number of terms= 10
mean= 225/10
= 22.5
Hence the mean for the first expression is 16 and the mean for the second expression is 22.5

Answer:
The answers are :
1. 5%.
2. 467.50 DKK.
Step-by-step explanation:
Given:
Discount on Monday of a good at 10 percent.
Increase discount on Friday would be 15 percent.
1. Difference between the percentage = .
So, the percentage increase in discount is .
2. First, the actual price means the price without discount should be calculated.
So,let the actual price be :
According to question,
of
=
Multiplying both sides by 100
=
Dividing both sides by 90
=.
And, now the price after the announcement of the discount
of
=% of
=
=
=.
So, the price after the announcement of the percent discount is DKK.
Therefore, the answers are :
1. 5%.
2. 467.50 DKK.
Y=2x+0.5
4.5=2x+0.5
4.5-0.5=4
4=2x
4÷2=2
x=2
so
