A weather report said there is a 60% chance of rain on Monday, and a 30% chance of rain on Tuesday. Based on the report, what is
sergey [27]

Answer:

The answer is 18 percent, or 9/50.

Step-by-step explanation:

We first convert the chance of rain on Monday into a fraction.

60%=60/100=3/5.

We then convert the chance of rain on Tuesday into a fraction.

30%=30/100=3/10.

Because the two events are independent(i.e. If it rains on Tuesday doesn't depend on if it rains on Monday) we multiply them together to get the probability they both happen. That chance is:

3/5 * 3/10=(3*3)/(5*10)=9/50(fraction form)=18/100=18%(percent form)

The intensity of light bulb measured in watts per square meter (w/m^2), varies inversely as the square of the distance d from th
krek1111 [17]

Answer:

I(7)   =  22.96 W/m²

Step-by-step explanation:

Let intensity of light, be  I(d)   where d is distance. There must be a proportionality factor K such as

I(d)  = K /d²

Now for d = 5 m    I(d)  =  K* 1/d²

then  45 * 25 = K

K =  1125

To find the intensity when the distance from the light bulb is 7 m away

I(7)   =  K / 49

I(7)   =  1125/49   W/m²

I(7)   =  22.96 W/m²
