Mrac [35]

Answer:

$2016 more

Step-by-step explanation:

Borrowed amount = $12000
Interest rate = 4.2% per year simple

Interest in 1 year:

$12000*4.2/100 = $504

Interest in 5 years:

$12000*4.2*5/100 = $2520

The difference between 1-year interest and 5-year interest:

$2520 - $504 = $2016

spayn [35]

Answer:

There was 32.5mm of rainfall on the seventh day.

Step-by-step explanation:

Mean of a data-set:

The mean of a data-set is the sum of all values of a data-set divided by the number of values in the data-set.

The mean daily rainfall for a week was 5.5mm.for the first six days the mean rainfall was 1mm.

This means that during the week(7 days), the total amount of rain was of:

$6*1 + x = 6 + x$

How much rainfall on the seventh day ?

This is x. We have that:

$\frac{6 + x}{7} = 5.5$

$6 + x = 7*5.5$

$6 + x = 38.5$

$x = 38.5 - 6 = 32.5$

There was 32.5mm of rainfall on the seventh day.
