Answer:

63 = 3 × 3 × 7

Step-by-step explanation:

Start dividing by the smallest prime divisor till you reach 1

Which is 3

63/3 = 21

21/3 = 7

7/7 = 1

So the prime factors are: 3,3,7

Answer:

  • strong negative linear correlation
  • -0.986

Step-by-step explanation:

You need to notice that when altitude goes up, temperature goes down. That means the correlation is negative.

The table shows the temperature decrease to be monotonic (nowhere does it go up when altitude increases), so the correlation is strong.

The strong negative correlation number available to you is -0.986.

___

If you want confirmation, you can put the numbers into your favorite graphing calculator and tell it to compute the correlation for you.

A drainage basin bordering the sea has an area of 7500 km2 . The average precipitation for this drainage basin is 900 mm year-1
Alexxx [7]

Answer with Step-by-step explanation:

The basic water balance dictates that "Amount of water flowing into the basin should be equal to the amount of water flowing out of it".

Mathematically

Water_{in}=Water_{out}\\\\P=E+Q+I

where

P = precipitation

I = Infiltration losses in the basin

E = Evapotranspiration

Q = is outflow from the basin

Applying the given values we get

900=E+\frac{22.5\times 10^{8}}{7500\times 10^{6}}\times 1000+100\\\\900=E+300+100

Part b)

From the above equation we get

E=900-400=500mm/year

The evaporation in cubic meters per year is

E'=0.5\times 7500\times 10^{6}=3750\times 10^{6}m^3/year
