Answer: 0.9927

Step-by-step explanation:

We assume that  the number of earthquakes that occur in Los Angeles follows normal distribution.

As per given , we have

\mu=36\\\\ \sigma= 3.6

Sample size : n= 35

Let \overline{x} be the sample mean.

Now ,

P(34

Hence, the probability that the mean of the sample is between 34 and 37.5. is 0.9927 .

A contractor is building the base of a circular fountain. On the blueprint, the base of the Fountain has a diameter of 18 centim
o-na [289]
The actual area is 454.1 ft.

You can use a ratio to find the actual diameter:
18cm/3cm = x/4ft.
x = 24 ft.

Then find the area using A=pi*r^2
A=pi*144
A=452.4 ft.

Answer:

 8.7 \times 10^{-5}

Step-by-step explanation:

Given that the diameter of a human hair

Given that the diameter of a spider's silk

Now we have to find how much greater is the diameter of a human hair than the diameter of a spider's silk. To find that we just need to subtract the given numbers. Since powers are not same so let's make them equal now we can easily subtract the coefficients that is 3 from 9  = (90-3) \times 10^{-6}

= 87 \times 10^{-6}

= 8.7 \times 10^{-5}
