Adensity curve for all the possible ages between 0 years and 100 years is in the shape of a triangle. what is the height of the triangle?

a. 0.08
b. 0.04
c. 0.01
d. 0.02

Option D) 0.02 is the answer.

Step-by-step explanation:

Given that a density curve for all the possible ages between 0 years and 100 years is in the shape of a triangle.

We know that probability for any event A = favourable outcomes/total outcomes

Because probability is expressed as a ratio, probability of an event is always positive and lies between 0 and 1.

Hence total probability is always 1.

Under density curve the area represents the total probability and hence total area =1

Area = Area of triangle = 1/2 bh

=

Hence altitude = 0.02

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:
