How many degrees greater is the mean temperature in week 2than in week 1

18 degrees

Step-by-step explanation:

To get the mean add up all of the values that you are given and divided it by how many there are.

Week One:

The values added up to 364 I then divided 364 by 7 to get a mean value of 52.

Week Two:

The values added up to 490, I then divided 490 by 7 to get a mean value of 70.

(In the above problems, I divided by 7 because there are 7 temperatures given)

I then subtracted 70 and 52 and got 18 degrees greater during week two.

the answer is su.k.my? ? co.kc

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:
