DENIUS [597]

Answer:

Diameter of the circle is $8\sqrt{2}$ units

Step-by-step explanation:

It is given that the vertices of the square fall on the circle.

So, the diagonal of the square is the diameter of the circle.

Also, the diagonal and the two sides of the square form a right angled triangle.

By Pythogoras theorem,

$hypotenuse^{2} =side^{2} +side^{2}$

= $8^{2} +8^{2}$

= $2(8^{2} )$

$hypotenuse=8\sqrt{2}$ units

Hence, the diameter of the circle is $8\sqrt{2}$ units

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.
